Abstract:This paper builds a numerical model of calculating the contact thermal resistance between IGBT and cooling substrate in drive-motor controller. And it analyses the influence degree of four factors on contact thermal resistance based on the model: the substrate material, the pressure, the surface roughness and the filling radiating material. As the core element in drive-motor controller, the heat radiation of IGBT is the most important problem, and the contact thermal resistance is a large part of thermal resis… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
