Cooler of intercooler

The utility model provides a chiller of a charge air cooler, which mainly solves the problems that the noise is heavy, the vibration is great, the cooling effect is affected by outside climatic factors and the device can not be suitable for different engines when the prior high-power fan cools the heat radiation of the charge air cooler in a blow-through way. The chiller is characterized in that the charge air cooler (2) is fixed inside a sealed chiller box body (1), an air inlet (9) and an air outlet (10) pass through the chiller box body (1) to be separated from the inner part of the box body and communicated with the outside world, a water inlet pipe (3) is provided with a water inlet control electromagnetic valve (5) and is connected with a water outlet pipe (4) through a bypass valve (6) and a bypass hose (7), and one side of the chiller box body (1) is provided with a temperature sensor (8). The chiller of the charge air cooler cools the charge air cooler by the circulating water, adjusts and controls the cooling temperature, provides the high pressure gas at a temperature necessary to the test for the engine operation, and has wide range of application.
