Therefore, a cooling box for heat treatment is proposed. Utility Model Content

At the same time, the locking nut 304 is tightened to fix the upper frame 302 and the lower frame 301, thereby clamping and fixing the metal casting.

The return pipe 8 is arranged in the water collecting tank 7 and has a filter plate 10 installed at one end thereof through threads; the filter plate 10 can filter impurities in the water collecting tank 7 to prevent impurities from entering the heat exchanger 4 and the spray pipe 5 through the return pipe 8 and causing blockage.

[0023] The air drying pipe 6 is fixedly installed on the inner wall of the cooling box 1, and an air outlet is provided on the air drying pipe 6. The air inlet pipe 601 is connected to the air drying pipe 6. The end of the air inlet pipe 601 away from the air drying pipe 6 is connected to a fan.
