Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation technology for chiller units, and in particular to a ventilation structure for chiller units. Background Technology
[0002] Water-cooled units remove heat generated by the equipment through the circulation of cooling water. However, the cooling water's temperature rises after absorbing heat, requiring the radiator to release this heat into the environment. The ventilation structure provides the necessary airflow to the radiator, accelerating heat exchange. External airflow enters through side vents driven by a fan and then exits through the top vent, ensuring the radiator's cooling.
[0003] To prevent large dust particles from entering the ventilation openings, small-hole ventilation openings are mostly used, such as the ventilation structure for chiller units disclosed in public technical solution CN222231029U. Alternatively, a dust filter is installed on the outside of the ventilation opening to filter the incoming airflow.
[0004] However, because both the ventilation holes and the dustproof mesh have small apertures, dust, insects, catkins and other foreign objects are easily trapped inside the holes, leading to increased clogging rates after long-term use and making cleaning inconvenient. Summary of the Invention
[0005] The purpose of this utility model is to provide a ventilation structure for a chiller unit, which can meet the normal ventilation of the chiller unit when the axial flow fan is rotating forward, and when it is rotating in reverse, the backflow will drive the spring plate more violently, so that the rubber ball at the bottom of the spring plate will impact the dust filter screen more significantly, generating a stronger local impact force. This, together with the axial flow fan, can achieve efficient cleaning of the dust filter screen, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a ventilation structure for a chiller unit, including a chiller side plate, a ventilation component for ventilation is provided on the side of the chiller side plate, a dust collection component for dust collection is provided at the air inlet of the ventilation component, and an auxiliary component is provided inside the ventilation component.
[0007] The ventilation assembly includes air ducts fixed to the left and right sides of the chiller side panel, and air vents are provided at the connection between the air ducts and the chiller side panel. An axial flow fan is installed inside the air duct, and a dust filter screen is provided on one side of the axial flow fan.
[0008] The auxiliary component includes a spring sheet welded inside the air duct, and the end of the spring sheet is wrapped with a rubber ball.
[0009] Preferably, when the spring sheet bends, the rubber ball collides with the dust filter screen, and the dust filter screen is a metal mesh.
[0010] Preferably, the ventilation assembly further includes a fan mounting bracket that is installed inside the air duct by external bolts, and the axial flow fan is installed inside the fan mounting bracket.
[0011] Preferably, the dust collection assembly includes a dust collection hood that is detachably installed outside the air inlet of the air duct, a corrugated pipe is fixed to one side of the dust collection hood, and a dust collection box is fixed to the end of the corrugated pipe, and a dust collection pump is installed on the side of the dust collection box.
[0012] Preferably, a connecting pipe is fixed between the vacuum pump and the vacuum box, and a filter plate is embedded inside the connecting pipe. An exhaust pipe for exhausting air is fixed to the top of the vacuum pump.
[0013] Preferably, the bottom of the dust collection box is threaded with a sealing cover, and the upper and lower sides of the dust collection hood and the air duct are welded with fixing ears.
[0014] Preferably, the fixing ear plate has a connecting hole inside, and the fixing ear plate can be detachably connected by external bolts.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The axial flow fan can provide normal ventilation for the chiller unit when rotating forward, and when rotating in reverse, the backflow will drive the spring plate more violently, so that the rubber ball at the bottom of the spring plate will hit the dust filter screen more violently, generating a stronger local impact force, which, together with the axial flow fan, can achieve efficient cleaning of the dust filter screen.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 4 A ventilation structure for a chiller unit includes a chiller side plate 1, a ventilation component 3 for ventilation is provided on the side of the chiller side plate 1, a dust collection component 2 for dust collection is provided at the air inlet of the ventilation component 3, and an auxiliary component 4 is provided inside the ventilation component 3.
[0028] The ventilation assembly 3 includes air ducts 301 fixed to the left and right sides of the chiller side plate 1, and air vents are provided at the connection between the air ducts 301 and the chiller side plate 1. An axial flow fan 302 is installed inside the air ducts 301, and a dust filter screen 304 is provided on one side of the axial flow fan 302.
[0029] The auxiliary component 4 includes a spring sheet 402 welded inside the air duct 301, and the end of the spring sheet 402 is wrapped with a rubber ball 401.
[0030] When the spring sheet 402 bends, the rubber ball 401 collides with the dust filter screen 304, and the dust filter screen 304 is a metal mesh. The ventilation assembly 3 also includes: a fan mounting bracket 303 that is installed inside the air duct 301 by external bolts. The axial flow fan 302 is installed inside the fan mounting bracket 303. The dust filter screen 304 can be installed by existing snap-fit installation or bolt installation methods, so as to realize the disassembly of the dust filter screen 304.
[0031] By adopting the above technical solution, an air vent is opened on the side plate 1 of the chiller, and air ducts 301 are set on both sides of the air vent. The air ducts 301, in which the axial flow fan 302 is installed, are located inside the chiller unit. When ventilating the chiller unit, the axial flow fan 302 rotates forward. The external airflow passes through the dust filter screen 304 and enters the air duct 301, thus ventilating the chiller unit. Dust is intercepted on the surface of the dust filter screen 304. When it is necessary to clean the dust filter screen 304, the dust collection component 2 is installed outside the air duct 301. At this time, the axial flow fan 302 rotates in reverse and can blow air back onto the dust filter screen 304. When the airflow passes through, it can drive the spring plate 402. When the filter bends, the rubber ball 401 at the bottom impacts the dust filter screen 304, loosening the initially adhered, light, and dry dust. The backflow of the axial flow fan 302 then peels off the deeper, firmly adhered particles and covers the entire filter screen surface, thus cleaning the dust filter screen 304. The axial flow fan 302, when rotating forward, can meet the normal ventilation needs of the chiller unit. When rotating in reverse, the backflow will drive the spring plate 402 more violently, causing the rubber ball 401 at the bottom of the spring plate 402 to impact the dust filter screen 304 more significantly, generating a stronger local impact force. This, combined with the axial flow fan 302, achieves efficient cleaning of the dust filter screen 304.
[0032] Specifically, such as Figure 4 As shown, the vacuuming assembly 2 includes a vacuum hood 201 that is detachably installed outside the air inlet of the air duct 301. A corrugated pipe 202 is fixed to one side of the vacuum hood 201, and a vacuum box 203 is fixed to the end of the corrugated pipe 202. A vacuum pump 205 is installed on the side of the vacuum box 203. A connecting pipe 208 is fixed between the vacuum pump 205 and the vacuum box 203, and a filter plate 207 is embedded inside the connecting pipe 208. An exhaust pipe 204 for exhausting is fixed to the top of the vacuum pump 205. A sealing cap 206 is threaded to the bottom of the vacuum box 203. Fixing ear plates 305 are welded to the upper and lower sides of the vacuum hood 201 and the air duct 301. A connecting hole 306 is opened inside the fixing ear plate 305, and the fixing ear plate 305 is detachably connected by external bolts.
[0033] By adopting the above technical solution, the filter plate 207 is disposed between the vacuum pump 205 and the vacuum chamber 203. The filter plate 207 can be a HEPA filter to prevent dust and impurities from entering the vacuum pump 205 and protect the internal structure of the vacuum pump 205. After the gas enters the vacuum pump 205 through the connecting pipe 208, it can be discharged to the outside through the exhaust pipe 204, making the air output by the vacuum pump 205 clean. At the same time, when the vacuum pump 205 is working, the dust on the dust filter 304 can pass through the vacuum hood. Dust enters the bellows 202 through 201 and then enters the dust collection box 203. After rotating the sealing cover 206, the dust inside the dust collection box 203 can be discharged, preventing secondary pollution caused by the axial flow fan 302 reversing and blowing dust off the dust filter screen 304. Through the set dust collection component 2, the dust collection cover 201 is detachably installed on the outside of the air duct 301. When cleaning dust, the dust collection pump 205 works, and the dust collection can ensure the immediate removal of dust and eliminate secondary pollution.
[0034] Working principle: An air vent is opened on the side panel 1 of the chiller, and air ducts 301 are set on both sides of the air vent. The air ducts 301, in which the axial flow fan 302 is installed, are located inside the chiller unit. When ventilating the chiller unit, the axial flow fan 302 rotates forward. The external airflow passes through the dust filter screen 304 and enters the air duct 301, thus ventilating the chiller unit. Dust is intercepted on the surface of the dust filter screen 304. When it is necessary to clean the dust filter screen 304, the dust suction hood 201 is installed outside the air duct 301. At this time, the axial flow fan 302 rotates in reverse and blows back towards the dust filter screen 304. When the airflow passes through, it can drive the spring plate 402, causing the spring plate 402 to bend. The rubber ball 401 at the bottom impacts the dust filter screen 304, loosening the initially adhered, light, and dry dust. Meanwhile, the backflow of the axial flow fan 302 can peel off the deep, firmly adhered particles and cover the entire filter screen surface, thus cleaning the dust filter screen 304. At the same time, the dust pump 205 works, and the dust on the dust filter screen 304 can enter the bellows 202 through the dust suction hood 201 and then enter the dust collection box 203. After rotating the sealing cover 206, the dust inside the dust collection box 203 can be discharged, preventing secondary pollution caused by the axial flow fan 302 reversing and blowing the dust off the dust filter screen 304.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
