Thermal design is necessary to use electronic equipment under a severe environment like inside the car. In the thermal design, we analyze the thermal resistance of each part, and consider the cost, manufacturability, reliability, etc., and reduce the thermal resistance so that each part becomes lower than the maximum operating temperature. Although thermal resistance is an important parameter of thermal design, there are few reports on thermal resistance measurement of the mounted state of electric components.
We focused on coils with large heat generation in the main components of power electronics circuits. We studied the thermal resistance of the coil when dissipating into a cabinet via a silicon sheet from both experimental and numerical analysis.
