Description

A compact water curtain fresh air device Technical Field

[0001] This utility model relates to the field of fresh air equipment, and in particular to a compact water curtain fresh air equipment. Background Technology

[0002] In data centers and server rooms, equipment generates a significant amount of heat during operation, requiring effective cooling systems to maintain the operating temperature. Water curtain ventilation systems are a common cooling method, employing isenthalpic humidification cooling technology to cool fresh air before delivering it into the server room, thus lowering the internal temperature.

[0003] Traditional water curtain fresh air systems mostly adopt a vertical column layout, which occupies a large area. Installation is often limited due to narrow channels. The planar water curtain structure results in a short contact path between air and water film, a small heat exchange area, and low utilization efficiency of natural cold source. To solve the above problems, we propose a compact water curtain fresh air device. Summary of the Invention

[0004] The purpose of this utility model is to provide a compact water curtain fresh air device, which has the advantages of small footprint and large heat exchange area.

[0035] Example 2:

[0036] Referring to Figures 1, 2, 3, and 4, a fixing frame 12 is bolted to the inner wall of the housing 1. A medium-efficiency filter 13, a primary filter 14, and a nylon filter 15 are slidably connected sequentially from the inside to the outside of the inner walls of the fixing frame 12. A retaining frame 16 is provided between each of the medium-efficiency filter 13, primary filter 14, and nylon filter 15. An outer frame 17 is provided on the surface of the fixing frame 12, and the nylon filter 15 is located inside the outer frame 17. A fixing pin 18 is provided through the inner walls of the outer frame 17 and the fixing frame 12. A sliding rod 19 is slidably sleeved on the inner wall of the fixing pin 18. The surface of the sliding rod 19 is open. A trapezoidal groove 20 is provided. A spring 21 is provided between one end of the slide rod 19 and the inner wall of the fixing pin 18. A steel ball 22 is provided on the inner wall of the fixing pin 18.

[0040] Brief description of the operation: Water pump 9 delivers water to water distributor 11 through connecting pipe 10. Water distributor 11 evenly sprays water onto evaporative wet film 3. Then, fan 6 draws air into the device from the side and through the evaporative wet film 3. The water on the evaporative wet film 3 evaporates, humidifying and cooling the air, thereby achieving the purpose of cooling the computer room. This technology fully utilizes the natural cold source of dry air for cooling, using the difference between the dry-bulb and wet-bulb temperatures of unsaturated air as the driving force, and water as the medium to humidify and cool the air. It adopts a compact V-shaped layout, with two water curtain components tilted towards each other. The installation part extending outward at the top facilitates fixing to walls and other structures, significantly reducing the equipment's footprint and effectively solving the installation limitations caused by narrow spaces. It can better adapt to the limited space environment such as computer rooms. To meet the installation requirements, the contact area and contact path between air and the evaporative wet film 3 are increased, thereby improving the effective heat exchange area. Pressing the pressing block 26 moves the trapezoidal groove 20, causing the steel ball 22 to enter the trapezoidal groove 20 and disengage from the fixing groove 23. Remove the fixing pin 18, and then take out the outer frame 17, nylon filter 15, primary filter 14, and secondary filter 13 in sequence for maintenance. After maintenance, put the outer frame 17, nylon filter 15, primary filter 14, and secondary filter 13 into the fixing frame 12, insert the fixing pin 18, and release the pressing block 26. The sliding rod 19, under the action of the spring 21, drives the trapezoidal groove 20 to reset. The reset of the trapezoidal groove 20 causes the steel ball 22 to engage with the fixing groove 23, fixing it and completing the maintenance, thus achieving the purpose of convenient maintenance.
