摘要
在450kW大功率电子束熔炼炉高压电源在冶炼以及提纯钛等难熔金属的过程中,IGBT等功率器件发热严重,如果不能及时将大量的热量散发出去,会造成高压电源运行不稳定,甚至烧毁IGBT等功率器件,造成较大的经济损失。针对传统的强迫风冷散热设计体积大,散热效果差等问题,提出了一种W型水冷板散热设计方式。通过对热源的发热量进行定量分析计算,并对水冷板的传热特性进行理论分析和公式计算,最终采用热管理和电子设备散热分析专业软件ANSYS ICEPAK,对散热系统进行了仿真。对比计算和仿真结果,验证了设计的正确性,进而得到进水流速的最优量。
In the process of melting and purifying titanium and other refractory metal, a lot of heat is emitted by IGBT and other power device of 450kW high-power electron beam melting furnace high voltage power supply. If these heat are not promptly dissipated, it will make the power supply unstable, and even burn IGBTs and other power de- vices, which may cause great economic losses. For the volume of traditional forced air cooling design is larger and the cooling effect is not good, a W-type water cooling design is presented. First, the heat loss is analyzed and calculated. Then the heat transfer characteristics of water-cooled panels are analyzed theoretically and calculated. And the professional thermal management and electronics cooling analysis software ANSYS ICEPAK is used to simulate the cooling system. By comparing the calculation results and simulation results, the design is verified to be correct and then get the optimal amount of water flow.
