Infineon Technologies partners with Boyd for Next Generation Electric Vehicle Inverter Cooling Systems

Infineon Technologies continues to partner with Boyd to develop improved systems and solutions for cooling electronics in hybrid and electric vehicles (HEV/EV). We see that EV and HEV production and consumer adoption is exponentially growing and will continue to as environmental standards push for cleaner, more compact, and less expensive transportation.

Customer demands require greater connectivity and more powerful internal electronics and vehicle operating systems in addition to already increased power requirements. New technologies and improved electronics ultimately result in additional waste heat. Without adequate thermal management, electronic reliability and lifetime required for vehicles running safely is significantly impaired to the point of device and system failure. Solutions like liquid cold plates and heat sinks safely remove heat from these crucial electronics to ensure reliable performance.

The Infineon/Boyd partnership enables our team to jointly design and produce fully optimized, highly effective cooling solutions for Infineon’s high-performance electronics for electric vehicles and hybrids.

Thermal Characterization of Infineon’s Double Side Cooled (DSC) MOSFETs and Boyd’s Dual Sided Liquid Cold Plates

The latest efforts of the Infineon/Boyd partnership produced a paper detailing the manufacturing of Boyd’s dual sided liquid cold plates, its thermal and hydraulic characteristics, and its impact on Infineon’s DSC Module. Engineers at both Infineon and Boyd collaborated in explaining the manufacturing process of the liquid cold plates, modeling and testing the DSC modules with a lab cooler and with Boyd’s DSC liquid cold plates, and comparison of a Si-IGBT DSC versus a SiC-MOSFET DSC module.

The Introduction of the HybridPACK™ and HybridKIT™

Boyd previously collaborated with Infineon to develop liquid cold plates for Infineon’s Double Side Cooled MOSFETS, the HybridPACK™ specifically designed for electric vehicles. Additionally, Boyd helped introduce the HybridKIT™, an all in one test kit ideal for research & development and initial prototyping. Due to excessive heat loads, sufficient cooling is necessary even for initial testing. Boyd’s specialty liquid cold plates dissipate large amounts of heat in a compact, lightweight form factor and offer greater design flexibility for developing prototype systems.

The HybridKIT™ includes electric drive modules, evaluation boards and drivers, and Boyd’s DSC liquid cold plate, which was designed specifically for this kit to represent production manufacturing performance and envelope.

The HybridKIT™ DSC

Additionally, Boyd is proud to help introduce the HybridKIT™ DSC, an all in one test kit ideal for research and development and initial prototyping. Due to high heat loads, sufficient cooling is necessary even for initial testing. The HybridKIT™ DSC includes 3 HybridPACK™ DSC power semiconductor modules, gate driver and logic board, DC-link capacitor, and an Boyd DSC liquid cold plate designed specifically for this kit to fully represent the specifications and requirements for faster prototype to production and scalable higher volume manufacturing.

What’s Next?

You have done your research and started running tests with the Infineon HybridPACK™ and HybridKIT™, what is the next step? Boyd is ready to work with your team to modify and design optimized DSC liquid cold plates for prototypes designed specifically for your system and ready for scalable manufacture. Boyd utilizes a number of manufacturing capabilities, including controlled atmospheric brazing (CAB), to hasten the cycle from prototype to high volume production of cost-effective, lightweight, high performance solutions ideal for electric and hybrid vehicles. Boyd can provide you with liquid cold plates, but can reduce landed costs by providing seals, gaskets, O-rings, custom moldings, and hoses to provide a more complete solution.  Still not sure about your next steps?
