[0026] Working principle: When the utility model is in use, the cooling circulating water is divided into two parts, the external circulation and the internal circulation. The operation of the external circulation cooling circulating water system is that the circulating water of the cooling tower 1 first passes through the external circulation water tank 3 and then enters the refrigerator 11, and then passes through the heat exchanger 13 and flows into the cooling tower 1 for buffer cooling. When the water inside the cooling tower 1 flows out, it will detect the water temperature when passing through the first detection group 9. When the circulating water passes through the refrigerator at a temperature higher than the set temperature, the refrigerator will work to cool down the internal circulation water. When the circulating water passes through the refrigerator at a temperature lower than the set temperature, the refrigerator will not work, and the heat exchanger 13 will cool down the internal circulation water. The operation of the internal circulation cooling circulating water system is divided into There are two cycles. When the temperature is higher than the set temperature, the operation of the internal circulation cooling water system is that the internal water of the internal circulation water tank 23 passes through the second control group 22 in the upper part of the U-shaped tube and runs to the equipment 21 to cool the equipment. Then the fifth valve in the second restriction group 27 is closed and the valve in the first restriction group 16 is opened. The internal circulation water will enter the refrigerator for cooling and then re-enter the internal circulation water tank 23 to cool the equipment 21 with the cooled water. When the temperature is lower than the set temperature, the operation of the internal circulation cooling water system is that the internal water of the internal circulation water tank 23 passes through the second control group 22 in the lower part of the U-shaped tube and runs to the equipment 21 to cool the equipment. Then the fifth valve in the second restriction group 27 is opened and the fifth valve in the first restriction group 16 is closed, and the internal circulation water will enter the heat exchanger 13, and the heat exchanger will cool the internal circulation water. Then the internal circulation water will re-enter the internal circulation water tank 23, and the cooled water will be used to cool the equipment 21. When the water temperature in the cooling tower 1 fluctuates due to weather temperature, the cooling circulation water system will determine whether the water circulation system cools the internal circulation water through the refrigerator 11 or the heat exchanger 13 according to the detection group.
