The semiconductor refrigerating fin 22 will cool the surface of the water tank 21, so that the water inside the water tank 21 exchanges heat with the inner wall of the water tank 21 when it is in contact with the inner wall, thereby reducing the temperature. When the pressure in the water tank 21 reaches a certain value, the spring 27 connected with the piston plate 28 on the circular ring frame 26 will be pulled away from one side of the circular ring frame 26, so that the spring 27 is stretched, and the water in the water tank 21 will enter the cooling pipe 25, thereby reducing the temperature of the surface of the cooling pipe 25. When the pressure container tank 1 contacts the cooling pipe 25, heat exchange occurs, the temperature of the surface of the pressure container tank 1 is reduced, and the effect of heat dissipation and cooling is achieved. The safety of the pressure container tank 1 during use is improved. The water after heat exchange is discharged from one end of the cooling pipe 25. When the medium needs to be used, the electromagnetic valve in the outlet pipe 5 can be opened to transport and use it.
