Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a stable cooling fan. Background Art

[0002] The primary function of a fan is to convert mechanical energy into kinetic and pressure energy of a fluid, thereby achieving functions such as conveying, pressurizing, ventilating, and removing heat from air or gas. A cooling fan is a special type of fan designed specifically for heat dissipation and cooling. It generates airflow to accelerate air flow over the surface of an object, removing heat and achieving a cooling effect.

[0003] Chinese utility model patent CN221096901 U discloses a cooling fan comprising a base, an air supply tube, a dust screen, an auxiliary cooling mechanism, and a blower mechanism. The air supply tube is mounted on the upper side of the base, an air outlet is provided on the right side of the air supply tube, a dust screen is detachably mounted on the left side of the air supply tube, and the blower mechanism is mounted within the air supply tube. The auxiliary cooling mechanism is mounted on the base and extends into the interior of the air supply tube, located to the right of the blower mechanism. This utility model facilitates cooling of the airflow and achieves improved cooling effects.

[0004] In order to facilitate the movement of the fan, the above-mentioned cooling fan is provided with universal wheels at the bottom of the base.

[0021] Specifically, one end of the return pipe 311 passes through the outer wall of the top side of the water storage tank 301 and extends to the inner wall of the top side of the water storage tank 301 .

[0022] In this embodiment, by setting up a water storage tank 301 and a return pipe 311, the cold water in the heat exchange pipe 310 is converted into warm water through heat exchange and flows into the return pipe 311, and then enters the water storage tank 301, and the used warm water is collected for recycling.

[0023] Specifically, the heat exchange tube 310 is in a zigzag shape.

[0024] In this embodiment, by providing the heat exchange tube 310, the meandering heat exchange tube 310 can increase the contact area with the cooling water, thereby improving the cooling efficiency.

[0025] Specifically, fixing columns 401 are fixedly provided on both sides of the top of the base 1 , and an air supply tube 402 is fixedly provided on the top of the fixing columns 401 .

[0026] In this embodiment, by providing the fixing column 401 and the air supply tube 402 , the fixing column 401 provides a firm support for the air supply tube 402 , thereby improving the stability of the air supply tube 402 .

[0027] Specifically, a dustproof net 403 is movably provided on one side of the air supply tube 402 .

[0028] In this embodiment, by providing a dustproof net 403 , the dustproof net 403 can filter dust in the air and prevent dust from entering the air supply tube 402 .

[0029] Specifically, a bracket 404 is fixedly provided on one side of the inner wall of the air supply tube 402 , a driving motor 405 is fixedly provided on the top of the bracket 404 , and an impeller 406 is fixedly provided on the output shaft of the driving motor 405 .

[0030] In this embodiment, by providing a bracket 404, a driving motor 405 and an impeller 406, after the driving motor 405 is started, the impeller 406 rotates along with the rotation of the output shaft of the driving motor 405, thereby promoting the circulation of airflow.

[0031] When in use, after using the universal wheel 204 to move the device to the place where the operation is required, the electric push rod 202 is started, and the telescopic end of the electric push rod 202 drives the movable plate 203 to move vertically. When the bottom of the support column 201 is in contact with the ground, the universal wheel 204 is limited, which improves the stability of the cooling fan. After the fixing is completed, the water pump 308 and the drive motor 405 are started. The water in the water tank 301 is pumped into the delivery pipe 309 through the pumping pipe 307 under the action of the water pump 308, and then enters the heat exchange pipe 310. At the same time, the impeller 406 moves along with the drive motor 405. The motor 405 rotates with the output shaft, and the air flows in from one side of the air supply tube 402. The dustproof net 403 filters the dust therein. When the filtered air flows through the heat exchange tube 310, the cold water in the heat exchange tube 310 absorbs heat and cools the air flow. The low-temperature air flow is finally discharged from the air outlet, and the used warm water flows from the heat exchange tube 310 into the return pipe 311 and finally enters the water storage tank 301. The filter net 304 filters the impurities in the circulating water for the next use, thereby realizing the recycling of cooling water and saving water resources.

After the operation is completed, the filter 304 is inserted into the water tank 301 by aligning it with the installation slot and closing the sealing door 305, thereby realizing the rapid disassembly and assembly of the filter 304, providing convenience for the staff and helping to improve the filtration efficiency and effect of the filter 304.

[0033] In summary, the stable cooling fan is provided with a support column 201, an electric push rod 202 and a movable plate 203. When the electric push rod 202 is started, the telescopic end of the electric push rod 202 drives the movable plate 203 to move vertically. When the bottom of the support column 201 is in contact with the ground, the universal wheel 204 is limited to ensure that the cooling fan can stay stably in the specified position when needed, thereby improving the stability of the cooling fan and reducing the risk of accidental movement or tipping of the cooling fan, thereby improving the cooling effect of the cooling fan. By providing the mounting block 303, the filter screen 304, the sealing door 305 And handle 306. During use, the circulating cooling water will continuously absorb and carry various impurities such as suspended matter, microorganisms, oxides and corrosive substances. The filter 304 can filter the impurities in the circulating water to maintain the stability of the circulating water quality, thereby better performing heat exchange and improving heat exchange efficiency. Pull the handle 306 to open the sealed door 305, and then pull out the filter 304 to facilitate the staff to clean or replace the filter 304, thereby avoiding the decrease in the filtering effect of the filter 304 due to clogging of the mesh of the filter 304, and helping to improve the filtering efficiency and effect of the filter 304.
