Because the cable still can be stained with the drop of water on the insulating layer surface behind foam-rubber cushion 431, blow to the insulating layer, under the effect of drop of water, can enough effectively improve the cooling rate to the insulating layer, can blow off the drop of water from the insulating layer surface again, do benefit to and carry out the rolling to the cable and store. Wind can circulate between the notch of the fixing groove 463 and the first connection plate 461, further accelerating the cooling of the insulating layer, and also making it difficult for the falling water drops to fall to the through hole. Under the connection effect of first connecting plate 461 and second connecting plate 462 for the cable can wear to establish in fixed slot 463 always, and the second connecting plate 462 of vertical setting can avoid the rivers that drop to first connecting plate 461, thereby forms the protection to fan 465, prolongs fan 465's life.

In actual use, with reference to fig. 9 and 12, since the wind force of the fan 465 is large, the wind blows from the through hole and finally blows the water in the water tank 42 under the redirection action of the fixing groove 463, especially the end of the water tank 42 close to the fixing groove 463, and the water in the water tank 42 cannot completely cover the insulating layer after fluctuating, thereby reducing the cooling effect on the insulating layer. To this end, a cover plate 47 is provided on the water tank 42, and two ribs 471 are fixedly attached to the same plate surface of the cover plate 47. When the cover plate 47 is placed on the water tank 42, the two ribs 471 can be in contact with the longitudinal inner bottom of the water tank 42. After the cover plate 47 is covered on the water tank 42, the water in the end of the water tank 42 close to the fixing groove 463 is not easy to fluctuate, thereby ensuring that the insulating layer can be completely covered by the water. The cover plate 47 is not easy to fall off from the water tank 42 under the limiting action of the two ribs 471, and the cover plate 47 is simple in structure and beneficial to cooling the insulating layer.
