Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning condenser technology, specifically to a condenser structure for a heat dissipation type automotive air conditioner. Background Technology

[0002] The heat-dissipating automotive air conditioning condenser is one of the important components of the automotive air conditioning system. Its core function is to cool and condense the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into a medium-temperature, high-pressure liquid refrigerant, and release the heat absorbed by the refrigerant in the evaporator and the heat generated by the compressor into the outside air. A search revealed an existing technology (Announcement No.: CN202322659157.2) describing a heat-dissipating automotive air conditioning condenser structure. The description states that "a movable brush is slidably connected to a dust cover covering the condenser surface. The inertia and elasticity of the vehicle's start-stop cycle drive the movable brush along a groove, cleaning the heat dissipation mesh of the dust cover, forming a dust-cleaning structure for the automotive air conditioning condenser. This effectively removes dirt or dust adhering to the mesh, facilitating smooth heat dissipation and ensuring the heat dissipation performance of the heat-dissipating automotive air conditioning condenser." However, the existing technology's elastically sliding movable brush is prone to jamming due to foreign objects or environmental factors, hindering the normal dissipation of localized heat from the automotive condenser. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a condenser structure for a heat-dissipating automotive air conditioner is provided to solve the problem that the movable brush, which slides elastically, is easily jammed by foreign objects, environmental factors, etc., thus hindering the normal dissipation of local heat from the automotive condenser.

[0004] To achieve the above objectives, a condenser structure for a heat-dissipating automotive air conditioner is provided, comprising: an automotive condenser body, wherein heat dissipation fins are mounted on the pipe surface of the automotive condenser body. The vehicle condenser body is covered with a top protective frame and a bottom protective frame. Ventilation protruding mesh is welded at equal intervals on the surface of the top protective frame, and ventilation concave mesh is welded at equal intervals on the lower end face of the bottom protective frame. The front and rear sides of the top protective frame are screwed to the bottom protective frame by fixing bolts. Upper air guide hoods are welded to the left and right sides of the top protective frame, and lower air guide hoods are welded to the left and right sides of the bottom protective frame. The outer end faces of the upper and lower air guide hoods are respectively provided with semi-circular mesh openings and arc-shaped mesh openings.

[0005] Furthermore, the vehicle condenser body is provided with a liquid inlet pipe at the left end and a liquid outlet pipe at the right end.

[0006] Furthermore, an mounting plate is welded to the side end plate of the vehicle condenser body, and an upper air guide shroud and a lower air guide shroud are respectively attached to the upper and lower surfaces of the vehicle condenser body.

[0007] Furthermore, the ventilation convex mesh and ventilation concave mesh are distributed on the corrugated plate surface of the top and bottom protective frames.

[0008] Furthermore, the inner side of the top protective frame is in contact with the heat dissipation fins through rubber vibration damping pads.

[0009] Furthermore, the inner wall of the upper end of the bottom protective frame is attached to the heat dissipation fins through a shock-absorbing support plate.

[0010] Furthermore, both the upper and lower air guide hoods have flow guiding cavities inside, which are respectively connected to the semi-circular mesh opening and the arc-shaped mesh opening.

[0011] The beneficial effects of this utility model are as follows: the condenser structure of the heat dissipation type vehicle air conditioner utilizes a protective ventilation structure composed of a top protective frame, a bottom protective frame, an upper air guide shroud, and a lower air guide shroud, which is installed on the outside of the condenser heat dissipation fins. Through the ventilation protruding mesh and ventilation concave mesh of the top and bottom protective frames, heat is dissipated from the inside to the outside. The particulate impurities attached to the mesh surface are more easily dropped or detached by gravity or vehicle operation factors, which facilitates the protection of the vehicle air conditioner condenser heat dissipation fins from dirt accumulation affecting normal heat dissipation. This effectively reduces the clogging of the dustproof mesh surface of the vehicle condenser, reduces the cleaning frequency, and improves the protection and stable filtration and heat dissipation effect of the vehicle air conditioner condenser.

[0017] 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.

[0018] Please refer to Figures 1 to 4 As shown, this utility model provides a condenser structure for a heat dissipation type automotive air conditioner, including: an automotive condenser body 1, with heat dissipation fins 13 installed on the pipe surface of the automotive condenser body 1. The upper and lower end faces of the automotive condenser body 1 are covered with a top protective frame 2 and a bottom protective frame 3. Ventilation protruding mesh 21 is welded at equal intervals on the surface of the top protective frame 2, and ventilation concave mesh 32 is welded at equal intervals on the lower end face of the bottom protective frame 3. The front and rear sides of the top protective frame 2 are screwed to the bottom protective frame 3 by fixing bolts 31. The upper air guide shroud 4 is welded to the left and right sides of the top protective frame 2, and the lower air guide shroud 41 is welded to the left and right sides of the bottom protective frame 3. The outer end faces of the upper air guide shroud 4 and the lower air guide shroud 41 are respectively provided with a semi-circular mesh opening 43 and an arc-shaped mesh opening 44.

[0019] The heat dissipation fins 13 of the vehicle condenser body 1 are covered and fixed with a top protective frame 2, a bottom protective frame 3, an upper air guide shroud 4, and a lower air guide shroud 41. The ventilation protruding mesh 21 and ventilation concave mesh 32 of the top protective frame 2 and the bottom protective frame 3 allow heat to dissipate from the inside to the outside. The particles and impurities attached to the mesh surface are more likely to fall off or detach due to gravity or vehicle operation. The semi-circular mesh opening 43 and arc-shaped mesh opening 44 on the side of the upper air guide shroud 4 and the lower air guide shroud 41 guide the external airflow into the protective frame. The mesh opening at the upper end helps to reduce the blockage of dust and impurities, making it easier to prevent dirt from adhering to the heat dissipation fins of the vehicle air conditioner condenser from affecting normal heat dissipation. This effectively reduces the blockage of the dustproof mesh surface of the vehicle condenser, reduces the cleaning frequency, and improves the protection and stable filtration and heat dissipation effect of the vehicle air conditioner condenser.

[0020] In this embodiment, a liquid inlet pipe 11 is provided at the left end of the vehicle condenser body 1, and a liquid outlet pipe 12 is provided at the right end of the vehicle condenser body 1. A mounting plate 14 is welded to the side plate of the vehicle condenser body 1, and an upper air guide shroud 4 and a lower air guide shroud 41 are respectively attached to the upper and lower surfaces of the vehicle condenser body 1. Ventilation protruding mesh 21 and ventilation concave mesh 32 are distributed at the corrugated plate surfaces of the top protective frame 2 and the bottom protective frame 3. The inner side of the top protective frame 2 is in contact with the heat dissipation fins 13 through rubber vibration damping pads 22. The upper inner wall of the bottom protective frame 3 is attached to the heat dissipation fins 13 through a shock-absorbing support plate 33.

[0021] In a preferred embodiment, the automotive condenser body 1 introduces and discharges liquid refrigerant through the inlet pipe 11 and outlet pipe 12, allowing the liquid refrigerant to be cooled and then transported to the compressor. The rubber vibration damping pad 22 and the shock-absorbing support plate 33 facilitate buffering and support of the top protective frame 2 and the bottom protective frame 3, preventing impacts to the inner heat dissipation fins 13. The ventilation protruding mesh 21 and ventilation concave mesh 32 of the top and bottom protective frames 2 and 3 have an arc-shaped structure, allowing airflow to pass more evenly across the entire filter surface. Dust adhesion is also more uniform, ensuring normal and stable heat dissipation of the automotive condenser body 1. Simultaneously, it protects against impacts from external particulate impurities that could deform or damage the heat dissipation fins 13. Furthermore, larger dust particles adhering to the arc-shaped mesh surface are more easily slid off the curved surface due to gravity, reducing mesh clogging, extending filter life, and decreasing cleaning frequency.

[0022] In this embodiment, both the upper air guide shroud 4 and the lower air guide shroud 41 have flow guiding cavities 42 inside, and the flow guiding cavities 42 are connected to the semi-circular mesh opening 43 and the arc-shaped mesh opening 44, respectively.

[0023] As a preferred implementation, the upper air guide shroud 4 and the lower air guide shroud 41 facilitate the guidance of the rapidly flowing airflow during vehicle operation, allowing the airflow to flow along the arc surfaces of the semi-circular mesh opening 43 and the arc-shaped mesh opening 44 into the air guide cavity 42, and then flow from the air guide cavity 42 into the protective frame, thereby promoting the airflow speed inside the protective frame and accelerating the heat dissipation efficiency.

[0024] The condenser structure of this utility model for a heat-dissipating automotive air conditioner effectively solves the problem in the prior art where the elastic sliding movable brush is easily jammed by foreign objects, environmental factors, etc., hindering the normal dissipation of local heat in the automotive condenser. It facilitates the protection of the heat dissipation fins of the automotive air conditioner from dirt accumulation, which affects normal heat dissipation, effectively reduces the clogging of the dustproof mesh of the automotive condenser, reduces the cleaning frequency, and improves the protection and stable filtration and heat dissipation effect of the automotive air conditioner condenser. It is suitable for the condenser structure of heat-dissipating automotive air conditioners.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
