| Summary |
In a typical power electronics package for a vehicle, a grease layer forms the interface between the direct bond copper layer or a baseplate and the heat sink. This grease layer has the highest thermal resistance of any layer in the package. Reducing the thermal resistance of the grease or other thermal interface material (TIM) can help to achieve Department of Energy FreedomCAR goals to use a glycol water mixture at 105 deg. C or even air cooling. This paper describes progress in characterizing the thermal performance of some conventional and novel TIMs. Experimental results for thermal resistance, in the context of automotive power electronics cooling, indicate that the thermal resistance of the TIM layer has a dramatic effect on maximum temperature in the power electronics package. |
