The outlet temperature of the inverter (HST) enters the radiator, and the radiator cools the hot inlet fluid using the fins that are in direct contact with the surrounding air. Fig. 10 illustrates the temperature distribution of the radiator system with an inlet temperature of 65 °C and inlet velocity of 0.2 m/s.
The main heat generating devices of the inverter are the power switch tube and the filter inductor, and the transformer. The efficiency of transformers and inductors can be customized by consultation with manufacturers. The loss of the power switch tube can be calculated by software simulation.
A. Thermal Analysis of the Air-Cooled Inverter In order to compare the performance of the immersion cooling with a conventional cooling design, an air-cooled inverter with heat sink is considered as the baseline model. The heat transfer coefficient of the aluminum heat sink is considered as 30 W/(m2K).
One of the most promising cooling techniques is indirect liquid cooling using cold plates. This paper studies the performance of a liquid cooling system on the junction temperature of a high-power inverter drive utilizing three legs of half-bridge modules (CAS120M12BM2 Silicon Carbide CREE MOSFET).
Its basic working principle is to utilize the heat expansion and contraction of coolants, generating an upward buoyancy force, which carries the thermal energy from the electronic device immersed in the immersion coolant to the top. Eventually, the heat is cooled by the condenser installed at the top through an external loop cooling source.
