[0016] 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.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] The following describes the embodiments in conjunction with the appendix. Figure 1-3 This utility model will be described in further detail.

[0019] A heat dissipation structure for an outdoor unit of an air conditioner includes a housing 1, an air inlet plate assembly 2, a condenser 3, and a fan 4.

[0020] The enclosure 1 is typically made of corrosion-resistant galvanized steel sheet, aluminum alloy, or engineering plastics. It has a cubic structure and is used to install the various components of the outdoor unit of the air conditioner.

[0021] The air intake panel assembly 2 includes an air intake panel 21, a rain shield 22, and a dustproof net 23. The dustproof net 23 is located between the air intake panel 21 and the rain shield 22. The air intake panel 21, the rain shield 22, and the dustproof net 23 form an easily detachable module.

[0022] The air inlet plate 21 is provided with multiple air guide units 211. These units are formed by protrusions or recesses on the surface of the air inlet plate 21. Specifically, in this embodiment, the air guide units 211 are shaped like a quadrangular prism, a hemisphere, or a cone, or any combination thereof. Multiple air inlets 212 are provided on the sides and bottom surface of the air guide units 211, while no air inlets 212 are provided on the top surface, thus forming an "eaves" structure. Figure 3 As shown, when the flow guiding unit 211 is a quadrangular pyramid, the air inlet 212 is located on the lower three inclined surfaces of the quadrangular pyramid. When the flow guiding unit 211 is a hemispherical shape, the air inlet 212 is located on the side and lower half of the hemisphere. When the flow guiding unit 211 is a cone shape, the cone protrudes from the surface of the air inlet plate 21, and the air inlet 212 is located on the side and lower half of the cone. When water droplets splash onto the surface of the flow guiding unit 211, the water droplets hang at the farthest end of the flow guiding unit 211 along the convex structure of the flow guiding unit 211, preventing the water droplets from flowing down the air inlet plate 21 along the flow guiding unit 211.

[0023] Multiple air inlets 212 are arranged on the air guiding unit 211 at different ventilation angles. The ventilation angles of the air inlets 212 on different air guiding units 211 are not parallel to each other. The air inlets 212 on the same air guiding unit 211 will be slightly offset in the four directions of up, down, left and right. Specifically, in this embodiment, the multiple air inlets 212 have different shapes. The shape of the air inlets 212 is one of the following: circular, elliptical, and elongated, or any combination thereof.

[0024] The distribution density of the airflow guiding unit 211 can be adjusted according to the heat dissipation requirements, with a higher density in areas with high heat dissipation requirements; the air inlet plate 21 is made of a metal thermally conductive material. In this embodiment, the air inlet plate 21 is made of galvanized sheet, which facilitates heat exchange with the outside environment and improves heat dissipation efficiency.

[0025] The rain shield 22 is equipped with a ventilation window 221 for introducing air into the housing 1. The rain shield 22 also includes rain shields 222, which are installed at an angle to the ventilation window 221. Multiple rain shields 222 are arranged in parallel. The angle of inclination of the rain shields 222 forms an acute angle with the ventilation angle of the ventilation window 221. Specifically, in this embodiment, the downward tilt angle of the rain shields 222 ranges from 45° to 60°. The cross-section of the rain shields 222 is designed as an airfoil or S-shape, with the upper edge facing outward and the lower edge facing inward. This allows rainwater to slide off the outer surface of the rain shields 222 under gravity, preventing it from accumulating on the inner surface, thus achieving rain-wind separation and reducing rainwater intrusion. A hydrophobic coating is sprayed onto the surface of the rain shields 222 to accelerate rainwater sliding off.

[0026] The condenser 3 is a finned tube heat exchanger, consisting of coiled tubes and metal fins passing through copper tubes. In this embodiment, the condenser 3 is configured as an L-shape, and the L-shaped condenser 3 includes both sides of the fan 4.

[0027] The structural relationship and working process of a heat dissipation structure for an air conditioner outdoor unit: The condenser 3 and fan 4 are mounted on the internal frame of the housing 1. The condenser 3 is positioned around the fan 4 on its air inlet side. An air inlet plate assembly 2 is mounted on one or more sides of the housing 1, forming an air inlet channel. The air inlet plate assembly 2 is positioned adjacent to the condenser 3, allowing gas to enter the housing 1 and contact the condenser 3. The sides of the condenser 3 are parallel to the air inlet plate assembly 2, with a distance of 15-30mm between them to ensure uniform airflow distribution and prevent excessive wind resistance due to insufficient distance. When the outdoor unit of the air conditioner is working, the fan 4 starts, creating negative pressure in the housing 1, drawing in outside air. When the airflow passes through the air inlet plate 21 of the air inlet plate assembly 2, most raindrops and large impurities are blocked by the rain shield 222 of the rain shield 22. Subsequently, the air passes through the dust filter 23, where the dust is filtered out. Then, after the airflow reaches the air inlet plate 21, it enters the housing 1 through multiple air inlets 212 at different angles on the air guide unit 211, causing the airflow, which was originally in the same direction, to be diverted by multiple air inlets at different angles. The air vent 212 disperses and breaks up the airflow into turbulent airflow from different directions and angles. This turbulent airflow blows onto the fins of the Xixiang condenser 3, which can effectively move the stagnant air on the fin surface, so that the cold air can have more full contact with the fins and pipes of the condenser 3, enhance the convective heat transfer effect, improve the heat exchange efficiency between the condenser 3 and the outside airflow, and enhance the heat dissipation capacity of the outdoor unit of the air conditioner. Finally, the heated air is exhausted from the casing 1 by the fan 4, and the rain baffle 22 and dust screen 23 also prevent rainwater and dust from entering.

[0028] The advantages of this utility model are: through the air inlet 212 with the air inlet angle on the air guide unit 211, while the air inlet plate group 2 protects the components inside the box 1, the airflow is guided to enter the inside of the box 1 at multiple angles and in a more turbulent manner to contact the condenser 3, thereby increasing the contact speed between the airflow and the condenser 3 and improving the heat exchange efficiency.

[0029] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
