[0002] As is well known, the development of plastic pipes in China is very fast, and the quality is constantly improving. A plastic pipe industry mainly composed of polyvinyl chloride pipes, polyethylene pipes and polypropylene pipes has been initially formed. Among them, polyethylene pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas transmission pipes, electrical and telecommunications protection sleeves, industrial pipes, and agricultural pipes. They are mainly used in urban water supply, urban gas supply and farmland irrigation. Polyethylene pipes need to be cooled and formed before molding.

[0003] In the existing PE pipe cooling device, a number of spray heads are arranged in a cooling box, and a large amount of water is sprayed by the spray heads to cool the PE pipes. The temperature of the cooling pipes is relatively high before they enter the cooling device. The internal air flow of the existing cooling device is not easy to circulate, resulting in a large amount of high-temperature gas and water vapor inside, thus affecting the cooling rate of the PE pipes.
