Description

Technical Field

[0001] This utility model relates to the field of fresh air conditioning cabinet technology, specifically a fresh air conditioning cabinet for fresh air cooling engineering. Background Technology

[0002] From an air quality perspective, traditional building ventilation relies heavily on natural ventilation or simple exhaust fans. However, in urban environments, outdoor air pollution is becoming increasingly severe, with frequent intrusions of pollutants such as smog, dust storms, and industrial exhaust gases, making it difficult for natural ventilation to guarantee the cleanliness of the incoming air. Simultaneously, indoor human activity, renovation residues, and the operation of various equipment continuously generate pollutants such as dust, formaldehyde, and odors, necessitating an effective air purification device to ensure healthy indoor air.

[0003] When existing fresh air conditioning cabinets are in use, their external filtration mechanisms are not good at filtering small dust particles entering the cabinet, which can lead to blockage of the heat dissipation fins inside the cabinet and reduce air exchange efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fresh air conditioning cabinet for fresh air cooling projects, which has the advantage of good filtration effect and solves the problem that the current fresh air conditioning cabinet has poor filtration effect, which leads to blockage of the heat dissipation fins inside the air conditioning cabinet and reduces the air exchange efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fresh air conditioning cabinet for fresh air cooling engineering, including a ventilation mechanism, a filter mechanism at the top of the ventilation mechanism, two exhaust mechanisms symmetrically arranged at the top of the filter mechanism, the ventilation mechanism including a cabinet for housing a compressor, condenser, and evaporator refrigeration devices, a plurality of heat dissipation holes symmetrically opened on the side of the cabinet, and a connecting plate at the top of the cabinet, two frames symmetrically arranged at the top of the connecting plate, and a plurality of heat dissipation fins equidistantly arranged inside the two frames.

[0006] Preferably, a gap is provided between the plurality of heat dissipation fins, the gap spacing is 3mm, and an electrostatic dust removal plate is inclinedly provided at the bottom end of the frame. The top end of the electrostatic dust removal plate is connected to the side of the bottom end of the frame away from the connecting plate, and the bottom end of the electrostatic dust removal plate is connected to the bottom end of the side of the connecting plate.

[0007] Preferably, the filtration mechanism includes a housing, with two through slots at the top of the housing, and openings on both sides of the housing near the frame, with filter plates installed at both openings.

[0008] Preferably, the inner side of the housing is attached to the side of the connecting plate, and the filter plate is provided with a plurality of filter holes at equal intervals, and the mesh size of the filter plate is between 16 and 20.

[0009] Preferably, each of the exhaust mechanisms includes a base, and the outer edge of the base is provided with several supports arranged in a ring array at equal intervals. The inner edges of the four supports are connected to several rings, and the spacing between the rings is between 5-8 mm.

[0010] Preferably, a rotary motor is provided at the top of the base, the output end of the rotary motor faces the base and extends to the bottom of the base, and a fan is connected to the output end of the rotary motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model comprises a housing, filter plates, and filter holes. The filter plates, located at both ends of the housing, filter dust from the air through a number of filter holes. The filter plates, with a mesh size of 16-20, can filter dust particles with a diameter between 0.9-1.25mm. Furthermore, a new type of nanofiber filter is used, which has a smaller pore size compared to traditional filter screens, enabling it to capture tiny particles in the air more efficiently and improve the filtration performance of the air conditioning unit.

[0013] 2. This utility model, by setting a connecting plate, a frame, heat dissipation fins and an electrostatic dust removal plate, improves the heat dissipation effect by setting the frame at both ends of the connecting plate and setting heat dissipation fins with a spacing of 3mm inside the frame. The inclined electrostatic dust removal plate can charge the particles in the air and then be attracted to the electrode plate with the opposite charge, which can further remove those fine dusts that are difficult to be intercepted by the filter and greatly improve the air purification accuracy.
