This paper presents a detailed cooling approach for traction motors which are mounted in hybrid electric vehicle (HEV) or battery electric vehicle (BEV). There are specific guidelines for the design of a traction motor in hybrid drives, such as the small and restricted packing area and on the other side, the need for a high power — and torque — density. For this vehicle powertrain application the...
Accurate prediction of operating temperatures in electronic parts at the component, package, board and system level computational fluid dynamics simulations, has engaged the engineering community for several years. The primary challenge was the difficulty of implementing accurate operating temperature predictions directly into system designs using near-exact physical models (known as detailed thermal...
The present work aims at studying the cooling performance of a thermoelectric device that integrated with integrated heat spreader (IHS) on a flip-chip plastic ball grid array (FC-PBGA) package. The new thermoelectric device herein is fabricated on the metal substrates by flip-chip assembly process. Thermal performance of the new package was comprehensive studied. The thermal resistances of IHS with/without...
