[ Detailed description ] of the invention
Referring to fig. 1 to 4, the present application is an air conditioner outdoor unit 100 for a vehicle, and in particular, the present embodiment is an air conditioner outdoor unit 100 for a vehicle mounted outside a cabin (not shown) of a truck. The vehicle air conditioner external unit 100 comprises a compressor 10, a condenser 20 and a fan 30, wherein the fan 30 is provided with a rotating shaft X and a wind surface 301 which is formed by rotation and is perpendicular to the rotating shaft X, the vehicle air conditioner external unit 100 is further provided with a mounting surface 40 of an air inlet 401, the condenser 20 is arranged between the air inlet 401 and the wind surface 301, and an included angle alpha of 0-60 degrees is formed between the wind surface 301 and the mounting surface 40. The design that the air inlet 401 of the vehicle air conditioner external unit 100 is provided on the installation surface 40 utilizes the large-area air inlet space of the installation surface 40 and the smooth air inlet route and angle between the air surface 301 and the installation surface 40, thereby improving the air flow and compact design of the vehicle air conditioner external unit 100. In addition, the vehicle air conditioner outdoor unit 100 further includes an electric control assembly 50, and the mounting surface 40 is provided with a heat dissipation port 402 at a position corresponding to the electric control assembly 50. The heat dissipation port 402 also effectively utilizes the mounting surface 40 to enhance the heat dissipation effect. Further, the electronic control unit 50 is provided with heat dissipation fins (facing the heat dissipation port, not shown) at positions corresponding to the heat dissipation port 402, so that heat dissipation can be achieved more directly and purposefully. The condenser 20 is plate-shaped parallel to the wind surface 301. Also, the condenser 20 covers 80% -100% of the air intake side of the fan 30. Based on the wide coverage of the condenser 20 to the air intake side, sufficient suction is ensured to assist in heat dissipation.
With continued reference to the drawings, the vehicle air conditioner outdoor unit 100 further includes a mounting bracket 70 assembled to the mounting surface 40 and capable of spacing the mounting surface 40 from an automobile mounting portion (not shown). Due to the design of the mounting bracket 70, the bottom of the mounting surface 40 is overhead and a sufficient air circulation gap is left, so that the air fluidity of the air inlet 401 and the heat dissipation port 402 is further improved. In addition, since the vehicle air conditioner outdoor unit 100 generates a large noise during operation, the design of the mounting bracket 70 can effectively absorb vibration, and avoid direct conduction to the automobile cab. The mounting bracket 70 comprises at least two groups of parallel bracket assemblies, each group of bracket assemblies comprises a cross beam 701 and fixing seats 702 positioned at two ends of the cross beam 701, and the cross beam 701 is made of steel pipes or aluminum alloy sections. Because the steel pipe or the aluminum alloy section bar is common in the market, a user can purchase freely and intercept different lengths according to different cab sizes. The air inlet 401 and the heat dissipation port 402 are arranged in parallel at the front part of the mounting surface 40, the external air conditioner 100 for a vehicle further comprises a dc-ac conversion module 60, and the compressor 10 and the dc-ac conversion module 60 are assembled at the rear part of the mounting surface. In the main structure of the vehicle air conditioner external unit 100, the compressor 10 and the dc-ac conversion module 60 are the heaviest, and are carried by the bracket assembly in this embodiment, and at the same time, the cross beam 701 is fixed to the mounting surface 40 of the vehicle air conditioner external unit 100, so as to produce reinforcement effect similar to a reinforcing rib. Moreover, as a source of gravity and a source of vibration, the geometric center of gravity G of the compressor 10 is designed to pass through one of the cross beams 701 for better load bearing and shock absorbing. The strength of the center of the top of the automobile cab is relatively weak, and the fixing base 702 for supporting the whole automobile air conditioner outdoor unit 100 is arranged at the left edge and the right edge with better strength, so that the stress of the automobile cab is optimized and dispersed. In this embodiment, the cross beam 701 is perpendicular to the advancing direction of the truck, the fixing base 702 is assembled on the left and right edges of the top of the automobile cab, and the fixing base 702 is mounted on the left and right sides of the automobile cab, so that the damage to the strength and the tightness of the automobile cab caused by the mounting structure such as the perforation on the top can be avoided.
In summary, the above description is only of the preferred embodiments of the present application, and is not limited thereto. For example, the fixing base in the above embodiment is assembled on the left and right edges of the top of the automobile cab, and in other embodiments, the fixing base may be assembled on the left and right edges of the back of the automobile cab or the upper and lower edges of the back of the automobile cab; in addition, in the above specific embodiment, the fixing seat is L-shaped, one surface is attached to the beam, the other surface is attached to the left and right sides of the automobile cab, and in other embodiments, the fixing seat may also be C-shaped, one surface is attached to the beam, and the other surface is attached to the top surface of the automobile cab, which can also achieve the technical effects of the present application. All simple and equivalent changes and modifications made in accordance with the claims and the specification of this application shall fall within the scope of the patent covered by this application.
