Description

Technical Field

[0001] This utility model relates to the technical field of screw air compressors, specifically a cooling device for screw air compressors. Background Technology

[0002] When a screw air compressor is in use, the temperature of the air will continue to rise after compression. If it operates at high temperatures for a long time, the service life of the equipment will be shortened. Therefore, the compressor needs to be cooled. A cooling device for a screw air compressor, disclosed in CN216044428U, includes a cylinder and a screw disposed within the cylinder. The cylinder has an air outlet at one upper end and an air inlet at one lower end. A cooling chamber is formed in the side wall of the cylinder. A water inlet valve and a circulating pump are respectively disposed on the upper and lower sides of the cylinder. A cooling box is disposed on one side of the cylinder. Fans are disposed at both ends of the cooling box. A cooling water pipe is disposed between the water inlet valve and the circulating pump. The cooling pipe is disposed within the cooling box and has heat dissipation fins. The aforementioned document improves compressor heat dissipation through an external cooling pipe and fan, while also facilitating disassembly and maintenance. This avoids the need to disassemble the entire compressor in case of cooling system failure, effectively extending equipment lifespan and reducing maintenance costs. However, the document uses water cooling, which generates water droplets that affect compressor performance. Therefore, we propose a screw air compressor cooling device to address the aforementioned issues. Utility Model Content

One end of the first water pump 11 is connected to the water supply tank 13 fixed below the mounting frame 3 via the water pumping pipe 12.

A semiconductor cooling chip 14 is installed on one side inside the water supply tank 13. A drive motor 15 is installed on the surface of the water supply tank 13 away from the semiconductor cooling chip 14. The output end of the drive motor 15 is fixed with an agitator 16 located inside the water supply tank 13. There are three sets of drive motors 15. The use of the drive motors 15 and agitator 16 on the side of the water supply tank 13 facilitates the cooling of the water inside the water supply tank 13. Please refer to Figures 1-5. An evaporator 9 and a micro compressor 10 are installed on the surface of the water pipe 8. A water droplet assembly 17 is installed at one end of the interior of the mounting frame 3. The water droplet assembly 17 includes a servo motor 1701, which is fixed inside the support block 2. The output end of the servo motor 1701 is fixed with a rotating screw 1702 rotatably connected inside the mounting frame 3. A scraper 1703 is connected to the rotating screw 1702. The scraper 1703 and the rotating screw 1702 are connected by a threaded connection. The upper end face of the scraper 1703 is in contact with the lower end face of the heat-conducting plate 4. The scraper 1703 can be driven to move by the rotating screw 1702, so that the scraper 1703 can slide under the heat-conducting plate 4, which is convenient for scraping the water droplets adhering to the lower end of the heat-conducting plate 4. Please refer to Figures 1-5. A water receiving assembly 18 is installed inside the fixed plate 6. The water receiving assembly 18 includes a second water pump 1801. The second water pump 1801 is installed inside the fixed plate 6, and one end of the second water pump 1801 is connected to the lower surface of the mounting frame 3 via a water receiving pipe 1802, passing through the fixed plate 6.

This, in conjunction with the water inlet pipe 1805, allows for efficient water collection. The use of this facilitates the drainage of water from inside the 1804 water storage tank.

[0015] Working principle: First, during use, the first water pump 11 inside the fixed plate 6 is turned on. The pump pipe 12 draws condensate from the water supply tank 13 into the condenser pipe 5, and then the condensate is discharged back into the water supply tank 13 through the connecting pipe 7. This facilitates the circulating water cooling at the bottom of the compressor body 1. During water cooling, the servo motor 1701 on the water droplet assembly 17 is turned on, causing the screw 1702 to drive the scraper 1703 to move in a threaded motion. This allows the scraper 1703 to scrape the water droplets at the bottom of the heat-conducting plate 4 above the mounting frame 3, making it easier to remove the water droplets at the bottom of the heat-conducting plate 4. Then, by turning on the second water pump 1801 on the water receiving assembly 18, the water receiving pipe 1802 absorbs the dripping water inside the mounting frame 3, and discharges the water into the water storage tank 1804 through the drain pipe 1803 for water collection. A water inlet pipe 1805 is installed on one side of the water storage tank 1804 to facilitate water discharge and improve the performance of the device. This is the operating principle of the screw air compressor cooling device. The evaporator 9 is model BC-93TMPF, and the micro compressor 10 is model Panasonic 6MS020ZBB41.
