Insulated-gate bipolar transistors (IGBTs) improve the energy efficiency and battery range for electrical vehicles (EVs) and the market for them is rapidly expanding. High-power IGBTs generate a significant amount of heat during operation and must be adequately cooled to ensure good electrical performance and reliability. This is typically accomplished by mounting the IGBTs to "cold plates" through which a liquid cooling fluid (typically water-glycol) is circulated. This technology faces a challenge: heat transfer within these cold plates should be maximized while maintaining a low pressure drop.NUCAP has developed a novel surface enhancement which significantly increases convective heat transfer. There is an opportunity implement these surface enhancements into a new class of GRIPMetal (a patented technology where metal hooks are distributed on metal surfaces) IGBT cold plates which have superior thermal-hydraulic performance. This has the potential to yield a technology that is low-profile and lightweight making it an attractive commercial offering for the growing EV and renewable energy sectors.The objective of this project is to support NUCAP in their development of GRIPMetal IGBT cold plates by performing the thermal-hydraulic design, optimization, and full performance characterization and validation of this technology. This will be accomplished through a combination of experimental characterization, numerical modelling, and reliability testing. The outcomes will include accurate quantification of GRIPMetal cold plate performance and comparisons to existing commercially available offerings. The project will also yield thermal-hydraulic models for GRIPMetal cold plates and cold-plate specific design tools which will allow NUCAP to design and optimize other sizes of cold plates for further applications.

绝缘栅极双极晶体管（IGBT）提高电动车辆（EV）的能源效率和电池范围，它们的市场正在迅速扩展。高功率IGBT在操作过程中会产生大量的热量，并且必须充分冷却以确保良好的电性能和可靠性。这通常是通过将IGBT安装到“冷板”上来实现的，通过该板循环液体冷却液（通常是水 - 甘油）。这项技术面临着一个挑战：在这些冷板中的传热应最大化，同时保持低压下降。NUCAP开发了一种新型的表面增强，可显着增加对流传热。有机会将这些表面增强功能实施到新的夹层式握把技术（一种在金属表面上分布在金属表面上的专利技术）IGBT冷板，这些板具有出色的热功能性能。这有可能产生一种低调和轻巧的技术，使其成为不断增长的EV和可再生能源领域的吸引人的商业产品。该项目的目的是通过执行热 - 杂种设计，优化，优化和完整的性能表征和验证该技术来支持其固定型IGBT冷板的发展。这将通过实验表征，数值建模和可靠性测试的结合来实现。结果将包括准确量化握把冷板性能以及与现有的市售产品的比较。该项目还将产生用于手柄冷板和冷板特定设计工具的热湿道模型，这些模型将使Nucap可以设计和优化其他尺寸的冷板，以进行进一步的应用。
