[0002] The closed cooling tower is a deformation and development of the traditional cooling tower. It is actually an evaporative cooling tower, a combination of a cooler and a wet cooling tower. It is a horizontal evaporative cooling tower. The process fluid flows through the pipe, and the air flows outside the pipe, and the two do not contact each other. The water in the bottom water storage tank is pumped by a circulation pump and then evenly sprayed down outside the pipe. It does not contact the process fluid hot water or refrigerant and the outside air, becoming a closed cooling tower, and enhancing the heat transfer and mass transfer effect through the sprayed water.
