Talk Title: Opportunities in High Voltage Power Module Packaging with Additive Manufacturing

Abstract: Electrification is an ongoing trend to mitigate the contribution of the aviation industry to the global carbon emissions. As a result, the onboard power systems are increasing in terms of the total power, and the specific power densities of the various power distribution and power electronic components must also increase to make this trend economically viable. One solution to increase the onboard power system specific power density is to increase the distribution voltage. However, operation at high voltages at high altitude poses significant packaging issues for the various power electronic components. In this talk, the role of the power module package for highly integrated power converters is established, and the challenges at > 1 kV operation are highlighted for modern power module packages. Elements of the power module package suitable for additive manufacturing are addressed from the state of the art to establish the various areas of opportunity motivated by these application challenges. Lastly, a mixed material additive manufacturing technique is presented to achieve a thin power substrate with high thermal performance with low electric field stress at the triple points within the power module.

Talk Title: Leveraging Implicit Geometry and Iterative Design Techniques to Maximize Heat Transfer

Abstract: In the aerospace industry, the transport of heat is critical to meeting the system’s performance requirements. In many applications, the current generation of thermal management systems is insufficient to meet future applications due to the increased thermal output of advanced avionic systems and the high weight and lower heat rejection capabilities of these decades-old thermal management systems. A new approach to heat exchanger design using implicit geometry allows a user to encapsulate shape, physics, and manufacturing processes in a single unified environment. Engineers can now overlay CAD geometry, simulated and empirical engineering data, and manufacturing process knowledge to design advanced, knowledge-driven, thermal solutions that scale from the lab to production. Implicit modeling technology enables a step-change improvement in speed & complexity utilizing an advanced platform that gives thermal design engineers control over their data and integrations so that they can deliver high-performance products over short timelines to meet the demands of these advanced aerospace systems. Utilizing implicit modeling and advanced manufacturing it is now possible to generate geometry with incredibly high surface areas for a given volume and large increases in thermal performance. Further, by coupling implicit modeling with advanced design exploration tools, like machine learning and artificial intelligence, it is possible to design optimal thermal solutions in timelines and configurations that were previously unimaginable. This presentation will demonstrate how this new approach to heat exchanger design has been currently demonstrated on an advanced heat exchanger with application to the aerospace, oil and gas, and chemical industries.

Talk Title: Flow Boiling in Microchannels for Cooling Small-Scale High Heat Flux Devices

Abstract: Spatially non-uniform and unsteady dissipative heat generation in high heat flux devices used in a number of applications is detrimental to their performance and lifetime constituting, at the same time, a bottleneck for further development. Flow boiling in microchannels constitutes one of the best options for cooling such devices, promising to meet requirements >1 MW/m2 since it can (i) yield very high heat transfer coefficients due to the dissipation of latent heat; (ii) maintain a uniform surface temperature, vital for the correct operation of components; and (iii) respond passively to alleviate localised “hot-spots”, as the heat transfer coefficient increases with heat flux. The presentation will include latest research findings in this area, highlighting both fundamental and practical aspects of the use of microchannels.

Professor David Huitink

Professor David Huitink, University of Arkansas

Talk Title: Additive Manufacturing for Electronics Thermal Management

Abstract: With the increase of electronic device power density, thermal management and reliability are increasingly critical in the design of power electronic systems. First, increased density challenges the capability of conventional heat sinks and cold plates to adequately dissipate heat. Secondly, higher frequency switching in high voltage, high current, wide bandgap power modules is creating intensified electromagnetic interference challenges, in which metallic heat removal systems will couple and create damaging current ringing. Furthermore, mobile power systems (such as in electrified aircraft) require lightweight heat removal methods that satisfy the heat loads dissipated during operation. In this effort we introduce an additive manufacturing pathway to produce custom heat removal systems using non-metallic materials, which take advantage of impinging fluid heat transfer to enable efficient thermal management. Herein, we leverage the precision of additive manufacturing techniques in the development of 3D optimized flow channels for achieving enhanced effective convective heat transfer coefficients. The experimental performance of convective heat removal due to liquid impingement is compared with conventional heat sinks, with the requirement of simulating the heat transfer needed by a high voltage inverter. Thermal and hydraulic performances will be discussed, along with the demonstration of this cooling approach in a high frequency T-type inverter intended for electrically driven aircraft propellers. The implementation of non-metallic materials manufacturing is aimed to reduce electromagnetic interference in a low weight and reduced cost package, which are presented using modeling and experimental validation of common mode noise induced by high voltage switching characteristics.

Biography: Professor Huitink's research portfolio spans the intersection of materials and thermal sciences, where fundamental thermophysical material behaviors can be leveraged for engineered applications. Herein, the interplay between atomic bonding, polymorphism, & nanoscale interactions with thermal transport, generation and storage have important implications in energy sciences, thermally active and functional materials, and materials processing. In particular, the Huitink lab works closely with Electrical Engineering collaborators in developing next generation, high density power electronics for electrified transportation and power conversion systems, and leverages advances in materials and thermal technologies for enabling High-Reliability electronics packaging. Recent efforts include use of additive manufacturing for hot-spot thermal management and transient temperature abatement, as well as interconnect fabrication technology development for enhanced lifetimes of electronic packaging through thermal cycling events. Moreover, the reliability efforts include developing novel methods for observing and isolating the physical mechanisms behind material degradation and failure in materials used in high power, high voltage electronic assemblies. Prior to joining Academia, Professor Huitink spent more than 5 years in industry, working in microelectronics technology development and manufacturing at Intel Corporation, where he served as Quality & Reliability Engineering Program Manager for Intel's Custom Foundry Division. There he pioneered the development of advanced methods of predicting reliability of silicon-based flip chip microelectronic packages, as well as developed testing protocols and FEA methods for governing Design for Reliability (DfR) guidance.

Talk Title: Atomic Layer Deposited Nanomaterials for Energy Conversion and Storage Devices

Abstract: With the increase of electronic device power density, thermal management and reliability are increasingly critical in the design of power electronic systems. First, increased density challenges the capability of conventional heat sinks and cold plates to adequately dissipate heat. Secondly, higher frequency switching in high voltage, high current, wide bandgap power modules is creating intensified electromagnetic interference challenges, in which metallic heat removal systems will couple and create damaging current ringing. Furthermore, mobile power systems (such as in electrified aircraft) require lightweight heat removal methods that satisfy the heat loads dissipated during operation. In this effort we introduce an additive manufacturing pathway to produce custom heat removal systems using non-metallic materials, which take advantage of impinging fluid heat transfer to enable efficient thermal management. Herein, we leverage the precision of additive manufacturing techniques in the development of 3D optimized flow channels for achieving enhanced effective convective heat transfer coefficients. The experimental performance of convective heat removal due to liquid impingement is compared with conventional heat sinks, with the requirement of simulating the heat transfer needed by a high voltage inverter. Thermal and hydraulic performances will be discussed, along with the demonstration of this cooling approach in a high frequency T-type inverter intended for electrically driven aircraft propellers. The implementation of non-metallic materials manufacturing is aimed to reduce electromagnetic interference in a low weight and reduced cost package, which are presented using modeling and experimental validation of common mode noise induced by high voltage switching characteristics.

Talk Title: Fundamental Challenges to Structured Surface Implementation with Real Thermal Systems

Abstract: Almost a century ago, the concept of ‘dropwise condensation’ was proposed, which states that steam condensation on hydrophobic surfaces can enhance heat transfer by up to 10 times compared to traditional 'filmwise condensation'. The potential of dropwise condensation has driven researchers to design thin (≈100 nm-thick) hydrophobic coating materials. However, the lack of long-term (>5 year) durability has been the main hindrance to coating utilization over the past century. In this talk, I will present our most recent progress in designing thin and durable hydrophobic coating materials for stable dropwise condensation. I will then cover design guidelines and challenges of creating durable and scalable surface structures for stable pool and flow boiling. Next, I will briefly discuss how micro/nanoengineered materials can be scaled up and applied to real life meter-scale industrial equipment through rational nanomanufacturing considerations. For anti-icing heat exchanger applications, we show that nanostructuring of the aluminum surface can delay frosting by 3x and increase overall heat pump system efficiency by 50%. Finally, I end my talk by briefly discussing novel approaches and use cases for structured surfaces, including: high temperature braze flow control in manufacturing, low and high temperature fouling, and advanced thermal management of power electronics.

Talk Title: Impact of 5G on Thermal Management of Telecommunications Networks

Abstract: Network operators are beginning the buildout of 5G wireless networks, with the enhanced bandwidth and extremely low latency of 5G networks anticipated to enable a range of applications, including self-driving cars, industrial automation, and digital health, to name a few. The demands that 5G applications will place on network infrastructure require continued innovations in wireless and wireline technologies. As one example, the low latency requirements of 5G-enabled applications is resulting in the emergence of so-called “edge” computing, where compute and data resources are located in small-scale data centers that are near the end user or application, with high-speed radio access networks (RANs) providing the needed application bandwidth. In this talk, I will discuss telecom industry trends brought on by 5G, how such trends are impacting the design of networks and devices, and the associated implications for thermal management in telecommunications networks.

Talk Title: Microfluidic Thermal Management for Heterogeneously Integrated Microsystems

Abstract: Heterogeneous integration is bringing in several thermal challenges. Two examples will be presented to illustrate these and some potential solutions. Power delivery to high performance computing hardware requires internal voltage regulators (IVR), which employ package embedded passive elements such as inductors. Close proximity of the passives and IVR requires independent thermal management of the passives. The passives are embedded within the packaging structure and do not have direct access to thermal management. The second example considers glass interposer based packaging of 5G and beyond mm wave wireless modules. Embedding of components within the interposer is a promising technology for compact heterogeneous integration. Thermal management of components such as power amplifiers for glass interposer based packaging presents significant challenges. As discussed, microfluidics presents promising solutions for both applications.

Talk Title: Low Thermal Resistance 3D Stacked IC Using WOW Technology

Abstract: Recently stacked DRAM is commercialized in response to the demand for increasing DRAM capacity, and it uses microbump technologies for stacking. When using microbump method, the thermal resistance in interlayer and in BEOL are large, so that total thermal resistance is larger. As the result total the temperature rise between top layer and bottom layer of stacked dies is large. At this point Tokyo institute of Technology reports the bumpless stacking technologies. When this method is used via last technology and the total thermal resistance is small, the temperature rise is also small. The total thermal resistance in microbump method is 1.54 K/W and the temperature rise at 22.6 W input power is 19.9 C. On the other hand, the total thermal resistance method in bumpless method is only 0.46 K/W and the temperature rise at 22.6 W input power is only 5.8 C.

Talk Title: Distributed Intelligence for Online Situational Awareness and Resilience in Electric Power Grids

Abstract: The electricity grid is constantly exposed and vulnerable to fast- and slow-dynamic threats ranging from unpredictable faults, weather-driven natural disasters, malicious cybersecurity attacks, and other random disruptions. With the growing demand to ensure higher quality electricity to end customers and mission critical systems and services, there is an urgent need to enrich the power delivery infrastructure resilience against disruptive events while reducing and mitigating such threatening risks. This calls for derivation and fundamental advancements of new, fast, and efficient analytical frameworks embedded in modular and localized solutions for online situational awareness and real-time decision making. This presentation seeks to provide analytical foundations to design, develop, and test next-generation smart sensors embedded with artificial intelligence and signal processing algorithms for online situational awareness in cyber-physical smart grids. Going beyond the traditional centralized monitoring paradigms, which are vulnerable to communication failures, delays, and cyber-attacks, the proposed solution for system monitoring and control paradigms enables fusing the online measurements in a distributed manner, translating the data to valuable information closer to where it is generated, i.e., distributed intelligence. Enabling a paradigm shift from sensing-only to sensing-and-actuating apparatus at the grid edge, the proposed solution would prepare the smart grids for a wide range of slow and fast-dynamic events while minimizing the disastrous consequences of such threats and maximizing its resilience to emergencies.

Talk Title: Don't Forget About 'Good, Old-Fashioned' Statistics

Abstract: As computing power becomes ubiquitous and incorporating machine learning (ML) and artificial intelligence methods becomes more convenient, it is easy to forget about statistical methods. However, these methods are powerful. Markov chains can enable efficient modeling of system operational regimes and application conditions; Monte Carlo methods can help us model and reproduce parametric and non-parametric data distributions, leading to e.g., better estimation of component/system parameters; and hypothesis testing is invaluable to generating useful features for application in AI/ML modeling. While it is blissful to believe that we can throw data at a deep neural network and let it sort out the modeling, this is ultimately naïve. Success demands that we use all tools at our disposal, and traditional statistical tools often have the edge when it comes to computational efficiency and interpretability.
