[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature. It uses the heat exchange between water and air to produce steam, which evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower. The water collection device of a cooling tower is divided into a water collection tank and a return water tank.
