Computational Fluid Analysis and Experiment Verification of a Liquid Cooling System for an Array Radar’s Transmit-Receive Module

The present research aims to analyze the performance of a liquid cooling plate for an array radar’s transmit-receive module by using computational fluid dynamics (CFD) and measurement experiments. Firstly, a model of the purchased cold plate was built in SolidWorks. Simulation parameters of the heat dissipation of the liquid cooling system were considered, which provide the basis for high-accuracy numerical simulation. In particular, the temperature measurement experiment was carried out in order to verify the results of the simulation. The comparison results have proved that a thickness of 0.7 mm of thermally conductive glue between high-power electronic equipment and the cold plate’s surface in the model is usable. The results in this article can be used as a reference for designing heat dissipation systems in high-power electronic equipment.
