The invention relates to the technical field of heat dissipation of power electronic transformers, particularly to a pump-driven phase-change cooling load system based on a power electronic transformer, and solves the problems that in the prior art, the cooling performance of pump drive phase change is poor, the integration degree of modules in the system is not high, and graded utilization of load loss cannot be realized. The system comprises a cooling device, a liquid supply device, a load device and a steam return device which are sequentially connected to form a loop, wherein a supercooledliquid working medium is output to the liquid supply device by the cooling device, is shunted and output to the load device by the liquid supply device, and is subjected to phase change into a gas-liquid two-phase working medium by the load device to realize cooling of the load device, and then the gas-liquid two-phase working medium is returned to the cooling device by the steam return device, is condensed and enters the next circulation, so that the efficient circulating cooling of the load is realized. The system has high module array expansion performance and pump drive phase change cooling performance.
Description
technical field [0001] The invention relates to the technical field of heat dissipation of power electronic transformers, in particular to a pump-driven phase-change cooling load system based on power electronic transformers. Background technique [0002] Power electronic transformers are power equipment that use power electronic conversion technology and electromagnetic induction principles to transmit electric energy. With the demand for light weight and miniaturization, the power consumption density of power electronic transformers has greatly increased. Traditional single-phase liquid cooling methods for power electronic transformers, such as silicone oil cooling, water cooling, etc., are increasingly difficult to meet their application requirements. In the single-phase liquid cooling method, due to the high viscosity of silicone oil and deionized water, when flowing through the transformer coil, the flow resistance is also large, so a high-power circulating pump is requ...
