A heat dissipation system is used for conducting heat dissipation on a power module of an alternating current/direct current conversion module and comprises an ice water machine, a heat exchanger, a first circulation pipeline, a second circulation pipeline, a first throttling valve and a control module. The ice water machine, the heat exchanger and the first circulation pipeline form a first circulation loop so as to circulate the low-temperature cooling liquid. The second circulation pipeline is arranged on one side of the power module to form a second circulation loop, and the heat source generated by the power module is absorbed by circulating the high-temperature cooling liquid. The control module opens the first throttle valve to introduce the low-temperature cooling liquid into the second circulation loop based on the temperature of the high-temperature cooling liquid greater than a temperature threshold so as to control the temperature to be less than or equal to the temperature threshold. The invention further relates to a solid-state transformer power supply device.

    一种散热系统,用以对交流/直流转换模块的功率模块进行散热,且散热系统包括冰水机、热交换器、第一循环管路、第二循环管路、第一节流阀及控制模块。冰水机、热交换器及第一循环管路形成第一循环回路,以循环低温冷却液。第二循环管路配置于功率模块的一侧而形成第二循环回路,且通过循环高温冷却液来吸收功率模块所产生的热源。控制模块基于高温冷却液的温度大于温度阈值,开启第一节流阀而将低温冷却液引入第二循环回路,以控制温度小于等于温度阈值。本公开还涉及一种固态变压器供电装置。
