[0043] In order to make the purpose and implementation of this application clearer, the exemplary implementation of this application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only part of the embodiments of this application, not all of the embodiments.

[0044] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "v-connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. A person of ordinary skill in the art will be able to understand the specific meanings of the above terms in this application based on the specific circumstances.

[0047] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0048] The compressor compresses low-temperature, low-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0049] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0050] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0051] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0052] The outdoor and indoor units of an air conditioner can be integrated into a single unit or separated into two units. When the outdoor and indoor units are two-unit units, the outdoor unit is also called the outdoor unit of the air conditioner, and the indoor unit is also called the indoor unit of the air conditioner.

[0053] Reference Figure 1 and Figure 2 According to the embodiment of the present application, the outdoor unit of the air conditioner can be a top-outlet type structure.

[0054] The air conditioner outdoor unit includes a housing assembly 10 .

[0055] The housing assembly 10 forms the overall framework of the air conditioner's outdoor unit. It is generally rectangular in shape, with an air inlet 101 positioned on its side and an air outlet 102 positioned at its top. The air inlet 101 allows outdoor air to flow into the housing assembly 10, while the air outlet 102 allows air inside the housing assembly 10 to flow out.

[0056] The air conditioner outdoor unit includes a heat exchanger 20. The heat exchanger 20 can be arranged in the housing assembly 10 corresponding to the air inlet 101. The heat exchanger 20 is located inside the air inlet 101 and is used to absorb heat from the air introduced into the air inlet 101 or transfer heat to the air.

[0057] The air conditioner outdoor unit may include a fan 30. The fan 30 may be disposed above the heat exchanger 20 corresponding to the air outlet 102. The fan 30 is configured to blow air so that the air flows from the air inlet 101 to the air outlet 102. The fan 30 may be an axial flow fan.

[0058] When the fan 30 is working, outdoor air enters through the air inlet 101 on the side of the housing assembly 10, exchanges heat with the heat exchanger 20, and is blown out through the air outlet 102 at the top.

[0059] The air conditioner outdoor unit may include refrigeration components located on the refrigerant circuit, such as a compressor, a gas-liquid separator, an expansion valve, and a four-way valve. These refrigeration components are installed in the housing assembly 10.

[0060] The air conditioner outdoor unit may include an electrical box 40 for realizing the electrical control function of the air conditioner outdoor unit. The electrical box 40 may be connected to a front panel (described below) of the housing assembly 10.

[0061] The housing assembly 10 is described in detail below:
