Description

Technical Field

[0001] The utility model relates to the field of air compressors, in particular to an air compressor hood type negative pressure cooling device in a confined space. Background Technique

[0002] When an air compressor operates in a confined space, a series of problems will be encountered, including safety hazards such as temperature rise, pressure instability, and noise problems. Since the air compressor generates a large amount of heat during operation, poor air circulation in the confined space will cause heat accumulation, increase the equipment temperature, and affect its performance and service life. At the same time, the pressure in the confined space may become unstable due to poor air circulation, thereby affecting the normal operation of the air compressor. In addition, the noise generated during the operation of the air compressor may be more obvious in the confined space, causing interference to the surrounding environment.

[0003] In terms of safety, if the air compressor fails, such as overheating or abnormal pressure, the confined space may increase the safety risk. To solve these problems and ensure that the air compressor is installed in a well-ventilated environment, if it must be installed in a confined space, in the prior art, generally, ventilation and exhaust equipment is installed to maintain air circulation; the air compressor is regularly inspected and maintained to ensure its stable operation; sound insulation materials or sound insulation covers are used to reduce noise transmission; and sufficient operating space is ensured for maintenance and repair work.

[0004] However, simply adding ventilation equipment to the confined space has a poor effect on reducing the heat generated by the air compressor. Therefore, a device is needed to efficiently cool the air compressor in the confined space. Summary of the Utility Model

[0005] To solve the problems existing in the prior art, the purpose of the utility model is to disclose an air compressor hood type negative pressure cooling device in a confined space, which can effectively perform negative pressure ventilation on the air compressor placed in the confined space, assist it in quickly dissipating heat, and avoid performance and service life problems of the air compressor caused by its own overhigh temperature.

[0006] To achieve the above effect, the present application discloses an air compressor hood type negative pressure cooling device in a confined space. The air compressor includes a housing, and a heat dissipation port is provided at the top of the housing. It is characterized in that: it includes an upper hood, the upper hood is communicated with an external fan unit through an air duct passing through the confined space, the upper hood is arranged above the heat dissipation port, the upper hood has a gradually shrinking section that tapers upward and a short straight mounting edge, and a rubber sheet is fixed to the mounting edge through bolts and a pressing plate on the mounting edge, and the rubber sheet extends downward along the mounting edge and abuts against the upper surface of the housing.

[0007] Further, the fan unit includes a fan power-connected to a motor, and a flange connection is provided between the air inlet of the fan and the air duct.

[0008] Furthermore, a support connecting plate is provided between the contraction section and the mounting edge of the upper cover, and the support connecting plate is fixedly connected to the bracket.

[0009] Furthermore, the bracket includes legs that support the outer frame, and an inner beam is arranged inside the outer frame. The support connecting plate is fixedly connected to the outer frame and the inner beam.

[0010] Furthermore, the legs of the bracket are arranged on the outer side of the housing.

[0011] Furthermore, the air compressor is arranged inside the housing.

[0012] The beneficial effects of the present utility model include:

[0013] This application discloses an air compressor hood-type negative pressure cooling device in a confined space. By arranging an upper cover capable of covering the heat dissipation opening at the heat dissipation opening position of the housing of the air compressor and connecting it to a fan unit outside the confined space through an air duct, negative pressure active cooling of the air compressor is achieved, thereby avoiding various problems caused by insufficient heat dissipation of the air compressor.

[0014] In addition, by arranging rubber sheets at the edge of the upper cover, sealing of the edge is achieved, and the heat dissipation and cooling effect is improved as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] The following will further elaborate on the detailed implementation manners of the present utility model in the form of combining with the attached drawings. However, the following embodiments only list the relatively preferred embodiments, which only play an explanatory role to help understand the present utility model and cannot be construed as a limitation to the present utility model.

[0022] Refer to Figures 1-3 , an air compressor hood-type negative pressure cooling device in a confined space. The air compressor includes a housing 1, and a heat dissipation opening 2 is provided at the top of the housing. It is characterized in that: it includes an upper hood 3, the upper hood is communicated with an external fan unit 5 through an air duct 4 passing through the confined space, the upper hood 3 is arranged above the heat dissipation opening, the upper hood has a converging section 31 that tapers upward and a short straight mounting edge 32, and a rubber sheet 8 is fixed to the mounting edge through bolts 6 and a pressing plate 7, and the rubber sheet 8 extends downward along the mounting edge and abuts against the upper surface of the housing 1.

[0023] The above-mentioned air compressor hood-type negative pressure cooling device in a confined space is used to improve the cooling efficiency of the air compressor. First, a heat dissipation opening is provided at the top of the housing of the air compressor to dissipate the heat generated inside. The upper hood directly covers above the heat dissipation opening and is communicated with the external fan unit through the air duct to form a negative pressure, guiding the external air into the confined space. The converging section design of the upper hood helps to concentrate the hot air flow, and the rubber sheet is fixed to the mounting edge of the upper hood through bolts and a pressing plate, and tightly abuts against the upper surface of the housing, ensuring that the hot air flow can be effectively guided and discharged.

[0024] The working process is as follows: When the air compressor is running, heat is generated, the heat rises to the heat dissipation opening, the converging section of the upper hood concentrates these heats, and through the negative pressure effect, the fan unit sucks in the external air and at the same time extracts the hot air from the confined space. The sealing effect of the rubber sheet prevents air leakage, ensuring that the hot air flow is effectively guided, thereby realizing the cooling of the air compressor.

[0025] Preferably, the fan unit 5 includes a fan 52 that is power-connected to a motor 51, and a flange connection is provided between the air inlet 53 of the fan and the air duct 4. A support connecting plate 33 is arranged between the converging section 31 and the mounting edge 32 of the upper hood 3, and the support connecting plate 33 is fixedly connected to a bracket 9.

[0026] More preferably, the bracket 9 includes a leg 91, the leg 91 supports an outer frame 92, an inner beam 93 is arranged inside the outer frame, and the support connecting plate is fixedly connected to the outer frame and the inner beam. The leg 91 of the bracket 9 is arranged on the outside of the housing. The air compressor is arranged inside the housing.

[0027] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
