Abstract
The invention discloses a power electronic device cooling system, which includes an air conditioning unit, a coolant pump (), a bypass throttling element () and a cooler. The coolant pump () takes liquid from a first condenser () of the air conditioning unit, a liquid coolant enters the cooler after being throttled by the bypass throttling element (), the low-temperature coolant cools a power electronic device at the cooler, and the coolant enters an evaporator () of the air conditioning unit to finish a cooling cycle after flowing out of the cooler. The power electronic device cooling system has a good cooling effect, and is high in cooling efficiency, small in equipment size and low in noise, and moreover, the power electronic device may be located in a sealed environment and prevented from influence of dust, and is internally clean and long in operation life.
