Thermal Analysis and Test of IGBT Water-cooling Radiator with Pin-fins
摘要
Abstract
In order to analysis the heat transfer performance of water-cooling radiator with pin-fins for insulated gate bipolar transistor (IGBT) module, the high quality grid of IGBT devices and complete radiator were generated by using HyperMesh software. The velocity distribution of water-cooling radiator’s internal channel, the temperature field distribution of IGBT devices and water-cooling radiator were calculated by FLUENT software. For verify the feasibility of the simulation method, a water-cooling test system for temperature rise experiment was built up. Because IGBT device cannot work in extreme condition for long time, loss characteristics and junction temperature influences each other, and the internal chip junction temperature is difficult to measure, a man-made simulated heat source is used to replace the IGBT device in experiment. The grid model of simulated heat source and water-cooling radiator were generated and calculated based on the experiment condition as input parameters. By the comparative analysis between the simulation result of measuring points and the experimental data on water-cooling radiator’s mounting surface, it indicate the relative error is less than 4%.关键词
