The HDPE double-wall corrugated pipe cooling device uses a water pump to pump water out of the water tank, and sprays it into the cooling pipe through the water spray pipe nozzle for water cooling, so that uniform cooling can be achieved. The corrugated pipe blows air into the drying nozzle through a blower, lifts up the work table through a hydraulic press, and pulls the fixed block to a fixed position through a fixed tension spring.

[0004] However, the above device cannot effectively cool both the inside and outside of the device as a whole during cooling, and lacks internal and external cooling structures, resulting in inefficient cooling. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
