摘要： A heat dissipation is used to dissipate heat for a power module (102A) of an AC-to-DC conversion module (10,10A,10B). The heat dissipation system (14) includes a chiller (162), a heat exchanger (182), a first circulation pipeline (164), a second circulation pipeline (166), a first throttle valve (168), and a control module (5). The chiller (162), the heat exchanger (182), and the first circulation pipeline (164) form a first circulation loop (L1) to circulate a low-temperature coolant (Lc). The second circulation pipeline (166) is disposed on one side of the power module (102A) to form a second circulation loop (L2), and absorbs a heat source generated by the power module (102A) by circulating a high-temperature coolant (Lh). The control module (5) opens the first throttle valve (168) to introduce the low-temperature coolant (Lc) into the second circulation loop (L2) based on a temperature of the high-temperature coolant (Lh) being greater than a temperature threshold so as to control the temperature to be less than or equal to the temperature threshold.
