When the gas is ejected, it is around the heat-conducting long sheet 72, which accelerates the cooling of the gas. At the same time, it can also accelerate the gas during the jetting process. The flow of gas in the cabin cabinet 1 is improved, and the fluidity of the gas in the cabin cabinet 1 is improved. During the rotation of the connecting long rod 92, the rotating boss 16 is driven to rotate through the connecting belt 15, and then the wind driving slot plate 17 is driven to rotate, so that the gas at the bottom of the cabin cabinet 1 can be stirred, and the flow of gas in the cabin cabinet 1 is accelerated, and the cooling effect is further improved. The cooled water finally flows into the water receiving box 81 through the water outlet pipe 10, and then is cooled through multiple cold water long pipes 83, and finally falls back into the cold water tank 82 to realize water circulation. While the wind driving slot plate 17 rotates, the driving gear 22 is driven to rotate through the outer gear ring 21, and the driving gear 22 drives the second worm 23 to rotate, the second worm 23 drives the second worm wheel 24 to rotate, and the second worm wheel 24 drives the third worm 26 to rotate.The third worm 26 drives the vertical long rod 810 to rotate through the third worm gear 25, and the vertical long rod 810 drives the fan long piece 88 to rotate. The fan long piece 88 can accelerate the air flow around the cold water long tube 83 and the heat dissipation fins 89, thereby accelerating the heat dissipation of the water inside the cold water long tube 83. The vertical long rod 810 drives the first gear 84 and the dispersion piece 87 to rotate, and the first gear 84 drives the second gear 85 and the cold water stirring piece 86 to rotate, so as to stir the water in the cold water tank 82 and accelerate the cooling of the water. The dispersion piece 87 can disperse the water flowing out of the cold water long tube 83 to improve the cooling effect of the water. Through multiple cold water treatments, the cooling effect of the water is guaranteed, and the cooling efficiency inside the cabin cabinet 1 is improved while saving water resources.
