Connecting components are provided on the upper and lower sides of the front surface of the support plate 2.

[0028] In this embodiment, the connecting component includes mounting plates 306 fixed to the upper and lower sides of the front surface of the support plate 2. Hollow water outlet plates 307 are fixed to the opposite sides of the upper and lower support plates 2. On the opposite sides of the upper and lower hollow water outlet plates 307, there are connected no less than two spray heads 308. The left sides of the upper and lower hollow water outlet plates 307 are connected by a pipeline. On the right side of the upper surface of the upper support plate 2, a water pump 309 is fixed.

Water is added to the interior of the water filling frame 1 through the filter screen 5, and then the water pump 309 can be turned on. The water pump 309 transports the water in the water filling frame 1 to the interior of the upper and lower hollow water outlet plates 307 through the input pipe 310, and sprays it through no less than two spray heads 308 on the upper and lower sides, cooling the PVC-U solid wall spiral pipe between the opposite sides of the upper and lower hollow water outlet plates 307. After cooling, the water flows back to the interior of the water filling frame 1 for collection. The water in the water filling frame 1 can be cooled by the heat dissipation fins 305 on the left side of the water filling frame 1. By starting the motor 302 to drive no less than two stirring paddles 304 to stir the water in the water filling frame 1, the uniformity of heat dissipation can be improved. By circulating and cooling the heat-dissipated water again, the cooling and forming effect can be improved.

[0036] (2) After the PVC-U solid wall spiral pipe is cooled by water, one end of the PVC-U solid wall spiral pipe passes through the hollow air outlet cylinder 403. The fan 405 is turned on, and the air blown by the fan 405 is transported to the interior of the hollow air outlet cylinder 403 through the pipeline, and then blown out through no less than two air outlet holes 404, so that the PVC-U solid wall spiral pipe can be air-dried, improving the practicability.
