Impact fin plate type precooler

The invention discloses an impact fin plate type precooler. An air inlet is formed in one side of a machine body, and an air filter is arranged in the air inlet; the spraying device sprays water in the water tank into a plurality of cold flow channels of the heat exchange plate bundle from top to bottom, water vapor is evaporated from environment air flowing from bottom to top, and the water temperature and the air temperature are reduced. The other path of environment incoming air horizontally flows through the hot runner alternately adjacent to the cold runner, the impact fins arranged on the wall face of the hot runner bend against the wind, dividing wall heat exchange between air in the hot runner and a water film in the cold runner is enhanced, the environment incoming air in the hot runner is cooled in an equal-humidity mode, and in other words, inlet air pre-cooling is achieved before the air enters indirect evaporation cooling. 本申请公开了一种冲击翅板式预冷器，机身的一侧设置有进风口且进风口内设置有滤风器；喷淋装置把水箱内的水自上而下喷淋到换热板束的多个冷流道内，向自下而上
