摘要：The invention discloses a power electronic device cooling system, which includes

an air conditioning unit, a coolant pump (31), a bypass throttling element (32) and acooler. The coolant pump (31) takes liquid from a first condenser (13) of the air

conditioning unit, a liquid coolant enters the cooler after being throttled by the bypassthrottling element (32), the low-temperature coolant cools a power electronic device atthe cooler, and the coolant enters an evaporator (11) of the air conditioning unit to finisha cooling cycle after flowing out of the cooler. The power electronic device coolingsystem has a good cooling effect, and is high in cooling efficiency, small in equipment sizeand low in noise, and moreover, the power electronic device may be located in a sealedenvironment and prevented from influence of dust, and is internally clean and long inoperation life.
