[0002] A closed cooling tower is a heat dissipation device used for cooling and temperature reduction of circulating media, and is commonly used for cooling circulating water in industrial production or civil air conditioners. It can cool high-temperature water to a temperature close to the atmospheric temperature, or more precisely, close to the wet-bulb temperature. Since it is a closed cycle, it can prevent water quality from being polluted, well protect the operation of the main equipment, and improve the service life. However, the current closed cooling towers still have the following deficiencies:
[0003] For example, the patent document with the application number 202220077308.6 discloses a closed cooling tower. This closed cooling tower solves the problem that when the existing closed cooling tower is in use, water deposits at the bottom of the cooling tower after heat exchange, and the temperature of the upper and lower layers of the water body is inconsistent, affecting the natural heat dissipation of the water body. In order to further improve the heat exchange efficiency between water and air and increase the cooling rate of the water body, but when it is used in winter, due to the too low temperature, the cooling water is easily frozen, thus affecting its normal use.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a closed cooling tower with an anti-freezing structure is proposed. Content of the Utility Model

[0024] The specific operation is as follows. When in use, start the warm air blower 504, so that the warm air blower 504 conveys warm air into the heating chamber 503 through the warm air duct 505. At the same time, the gas will be discharged from the exhaust port 506, so that the hot air in the heating chamber 503 circulates, maintaining continuous heating to prevent the water in the water collecting tank 2 from freezing. If the water freezes due to too low temperature, the heating coil 502 can be electrified to continuously heat the water collecting tank 2, so as to quickly thaw.
[0025] Please refer to Figure 4 Inside the air inlet frame 3, a filtering component 6 for filtering is arranged. The filtering component 6 includes a primary filter screen 601, a dust removal net 602 and an activated carbon filter screen 603. The primary filter screen 601 is arranged inside the air inlet frame 3, and the dust removal net 602 is installed inside the primary filter screen 601. The activated carbon filter screen 603 is arranged inside the dust removal net 602. The filtering component 6 further includes a microporous waterproof membrane 604 and a sealing frame 605. The microporous waterproof membrane 604 is arranged on the inner surface of the activated carbon filter screen 603.

[0026] The specific operation is as follows. When in use, start the exhaust fan 17, so that the exhaust fan 17 draws air through the air inlet frame 3. After the outside air enters the air inlet frame 3, the large particle impurities in the air are filtered by the primary filter screen 601. After the air passes through the dust removal net 602, the smaller impurities are intercepted and filtered. The activated carbon filter screen 603 can adsorb the harmful substances in the air. The microporous waterproof membrane 604 can prevent water from adhering to the surface of the filter screen without affecting the passage of gas, avoiding affecting the normal use of the filter screen. The sealing frame 605 can prevent the water sprayed down from entering the inside of the filter screen.
[0027] Please refer to Figures 1 to 2, at the upper end of the left surface of the main tower body 4, a water inlet 7 is installed, and a cooling coil 8 is arranged at the inner end of the water inlet 7. A water outlet 9 is arranged at the water outlet end of the cooling coil 8. On the left side of the upper surface of the fixed bottom plate 1, a drainage pump 10 is installed, and a drainage pipe 11 is connected to the front end of the drainage pump 10. The upper end of the drainage pipe 11 is connected to the outer end of the water outlet 9. On the right side of the upper surface of the fixed bottom plate 1, a water extraction pump 12 is installed, and a water extraction pipe 13 is connected to the front end of the water extraction pump 12. The front end of the water extraction pipe 13 is connected to the right end of the front surface of the water collection tank 2. A water delivery pipe 14 is arranged at the rear end of the water extraction pump 12. The upper end of the water delivery pipe 14 penetrates through the upper end of the right surface of the main tower body 4 and extends into the main tower body 4. A multi-way water collection pipe 15 is installed at the upper end of the water delivery pipe 14. A spray head 16 is installed on the lower surface of the multi-way water collection pipe 15. An exhaust fan 17 is installed on the upper surface of the main tower body 4, and two groups of exhaust fans 17 are symmetrically arranged;
[0028] The specific operation is as follows. During use, hot water is conveyed into the cooling coil 8 through the water inlet 7. The water extraction pump 12 is started, so that the water extraction pump 12 extracts the water in the water collection tank 2 through the water extraction pipe 13 and conveys it into the multi-way water collection pipe 15 through the water delivery pipe 14. Then, the multi-way water collection pipe 15 sprays the water onto the cooling coil 8 through the spray head 16 to form a water film. At the same time, the exhaust fan 17 is started, so that the exhaust fan 17 sucks air inward, and heat exchange is realized by contacting the water film. After the gas becomes hot, it is discharged, and the hot water in the cooling coil 8 will become cold. The drainage pump 10 is started to discharge the cooled water through the drainage pipe 11.
[0029] In summary, as Figures 1 to 4As shown, when the closed cooling tower with an anti-freezing structure is in use, first, hot water is transported into the cooling coil 8 through the water inlet 7. At the same time, the water pump 12 is started, so that the water pump 12 pumps out the water in the water collecting tank 2 through the water suction pipe 13 and transports it into the multi-way collecting pipe 15 through the water delivery pipe 14. Then, the multi-way collecting pipe 15 sprays the water onto the cooling coil 8 through the spray head 16 to form a water film. At the same time, the exhaust fan 17 is started, so that the exhaust fan 17 sucks air through the air inlet frame 3. After the outside air enters the air inlet frame 3, the large particle impurities in the air are filtered through the primary filter screen 601. After the air passes through the dust removal net 602, the smaller impurities are intercepted and filtered. The activated carbon filter screen 603 can adsorb the harmful gas substances in the air. The outside gas realizes heat exchange by contacting the water film, and the gas is discharged after getting hot. The hot water in the cooling coil 8 will become cold. Then, the drain pump 10 is started, so that it pumps out the cooled water through the drain pipe 11 and discharges it through the water outlet 9. During the use of this device, the warm air blower 504 is started, so that the warm air blower 504 transports warm air into the heating chamber 503 through the warm air pipe 505. At the same time, the gas will be discharged from the exhaust port 506, so that the hot air in the heating chamber 503 circulates and keeps heating continuously to prevent the water in the water collecting tank 2 from freezing. If the water freezes due to too low temperature, the heating coil 502 can be electrified, so that the heating coil 502 continuously heats the water collecting tank 2 to quickly thaw the ice.
