[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the vaporization of the steam takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature.

[0003] The existing environmental protection and energy-saving technology of cooling towers often adopts an environmental protection and energy-saving closed cooling tower disclosed in the announcement number CN220380315U, which sets a condensation hood so that the air discharged through the exhaust port contacts the inner wall of the condensation hood, and the water vapor in the air condenses into water droplets on the inner wall of the condensation hood, and then falls into the interior of the closed cooling tower body through the exhaust port to participate in the circulation. However, the condensation column is set outside the tower body, and some hot air will be lost, which will cause waste of cooling water.
