[0052] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0053] Reference is made below Figures 1-5 to describe the outdoor unit 100 and the air conditioning equipment according to an embodiment of the present utility model.

[0054] Referring to Figures 1-2 , for the outdoor unit 100 according to an embodiment of the first aspect of the present utility model, the outdoor unit 100 includes: an outdoor unit housing 1, an outdoor heat exchanger 2, an outdoor fan, a compressor assembly 3, an electric control box component 4, and a heat dissipation pipe disposed inside the outdoor unit housing 1. A middle partition 11 is provided inside the outdoor unit housing 1, and the middle partition 11 divides the space inside the outdoor unit housing 1 into a blower chamber 12 and a compressor chamber 13 arranged in the left-right direction. The outdoor heat exchanger 2 and the outdoor fan are disposed in the blower chamber 12, the compressor assembly 3 is disposed in the compressor chamber 13, and at least a part of the electric control box component 4 is located in the compressor chamber 13.

[0055] Among them, at least a part of the electric control box component 4 being located in the compressor chamber 13 may include the following several situations: for example, a part of the electric control box component 4 is located in the compressor chamber 13, and another part of the electric control box is located in the blower chamber 12; for another example, the electric control box component 4 is entirely located in the compressor chamber 13.

[0056] An air inlet 14 and an air outlet 15 communicating with the blower chamber 12 are formed on the outdoor unit housing 1. During the operation of the outdoor fan, the outdoor fan can drive air to enter the outdoor unit housing 1 from the air inlet 14, exchange heat with the outdoor heat exchanger 2, and then be discharged to the outside of the outdoor unit housing 1 through the air outlet 15 after heat exchange.

[0057] The compressor assembly 3 includes a compressor, and the compressor assembly 3 can play a role in compressing and driving the refrigerant in the refrigerant circulation loop of the outdoor unit 100.

[0058] The electric control box component 4 includes a box body 41 and an electric control module 42 disposed inside the box body 41. The box body 41 has an air inlet 411 and an air outlet 412. The air inlet 411 communicates with the compressor chamber 13, and the air outlet 412 communicates with the blower chamber 12. The electric control module 42 can be electrically connected to the outdoor fan, the compressor assembly 3, etc. disposed inside the outdoor unit housing 1, and can be used to control the operation of components such as the outdoor fan and the compressor assembly 3. During the operation of the outdoor unit 100, the operation of the outdoor fan drives air to enter the box body 41 through the air inlet 411, and the air flows through the electric control module 42 to cool it by air cooling.

[0059] The heat pipe 7 has a heat dissipation channel for the flow of heat exchange medium, and the heat pipe 7 is thermally connected to the electric control module 42. The heat exchange medium takes away the heat from the electric control module 42 by flowing in the heat dissipation channel to achieve heat dissipation of the electric control module 42.

[0060] According to the outdoor unit 100 of the embodiment of the utility model, by making the box body 41 of the electric control box component 4 have an air flow inlet 411 and an air flow outlet 412 and setting a heat dissipation pipe 7, during the operation of the outdoor unit 100, the operation of the outdoor fan drives the air flow to enter the box body 41 through the air flow inlet 411, and the air flow flows through the electric control module 42 to cool it, and the heat exchange medium takes away the heat on the electric control module 42 by flowing in the heat dissipation channel of the heat dissipation pipe 7. In this way, the air flow entering the box body 41 through the air flow inlet 411 and the heat exchange medium in the heat dissipation pipe 7 dissipate heat to the electric control module 42 at the same time, which is beneficial to improve the heat dissipation efficiency and heat dissipation effect of the electric control module 42, reduce or avoid the adverse effect of the electric control box component 4 being in a high temperature condition on the operation of the outdoor unit 100, and further reduce or avoid the adverse effect on the air conditioning capacity of the air-conditioning equipment.

[0061] refer to Figures 1-2 According to some embodiments of the present invention, the outdoor housing 1 is formed with an air inlet 16, which is located on the side wall of the compressor cavity 13, and the air inlet 16 connects the airflow inlet 411 with the external space of the outdoor unit 100. During the operation of the outdoor unit 100, the operation of the outdoor fan causes an air pressure difference between the fan cavity 12 and the external space of the outdoor unit 100, so that the airflow in the external space can enter the box body through the air inlet and the airflow inlet 411 under the action of the air pressure difference, and then flow through the electric control module 42 in the box body 41 and fully exchange heat with the electric control module 42 to achieve heat dissipation of the electric control module 42, and then the airflow can flow out of the box body 41 through the airflow outlet 412 and enter the fan cavity 12.

[0062] During the operation of the outdoor unit 100, the temperature of the air flow inside the outdoor casing 1 is relatively high. If the air flow inside the outdoor casing 1 is used to dissipate the heat of the electric control module 42 of the electric control box component 4, the heat dissipation effect is relatively poor. In this way, dissipating the heat of the electric control module 42 through the air flow in the external space of the outdoor casing 1 is beneficial to improving the heat dissipation effect, further reducing or avoiding the electric control box component 4 being in a high temperature condition, thereby reducing or avoiding the normal operation of the electric control box component 4 being affected by the high temperature, thereby avoiding affecting the normal operation of the outdoor unit 100.

[0063] For example, when the outdoor unit 100 is applied to a variable-frequency air-conditioning device, the heat dissipation effect can be improved by dissipating heat from the electronic control module 42 through the airflow in the external space of the outdoor unit housing 1, which can effectively prevent the outdoor unit 100 from self-limiting frequency protection due to the heat generated by the electronic control box component 4 under high-temperature working conditions, so that the air-conditioning device can achieve a good air-conditioning effect.

[0064] By forming an air inlet 16 on the outdoor unit housing 1 that communicates the air inlet 411 with the external space, it is convenient for the airflow in the external space to smoothly enter the box body 41 through the air inlet 411 via the air inlet 16; in addition, by making the air inlet 411 communicate with the external space of the outdoor unit 100, during the operation of the outdoor unit 100, the operation of the outdoor fan will create a pressure difference between the fan chamber 12 and the external space of the outdoor unit 100, so that the airflow in the external space can enter the box body 41 through the air inlet 411 to dissipate heat from the electronic control module 42, and then flow out of the box body 41 through the air outlet 412 to the fan chamber 12. The temperature of the airflow in the external space of the outdoor unit 100 is lower than the temperature of the airflow inside the outdoor unit 100. Therefore, dissipating heat from the electronic control module 42 through the airflow in the external space of the outdoor unit 100 is beneficial to improving the heat dissipation effect.

[0065] Reference Figures 1-2 , according to some optional embodiments of the present invention, an intake space 5 is defined between the electronic control box component 4 and the side wall of the compressor, and the intake space 5 communicates the air inlet 16 with the air inlet 411. By defining an intake space 5 between the electronic control box component 4 and the side wall of the compressor that communicates the air inlet 16 and the air inlet 411, it is convenient for the airflow to smoothly enter the box body 41 through the air inlet 411 to dissipate heat from the electronic control module 42.

[0066] During the operation of the outdoor unit 100, the operation of the outdoor fan creates a pressure difference between the inside of the fan chamber 12 and the external space of the outdoor unit 100, so that the airflow in the external space enters the outdoor unit housing 1 through the air inlet 16 under the action of this pressure difference, then flows towards the air inlet 411 through the intake space 5 and can enter the box body 41 through the air inlet 411 of the box body 41, and flows through the electronic control module 42 in the box body 41 to fully exchange heat with the electronic control module 42 to achieve heat dissipation of the electronic control module 42. Then, the airflow can flow out of the box body 41 through the air outlet 412 and enter the fan chamber 12.

[0067] Reference Figures 1-2, according to some alternative embodiments of the present utility model, in the left - right direction, the air inlet 16 is located on the side of the compressor chamber 13 away from the blower chamber 12. By making the air inlet 16 located on the side of the compressor chamber 13 away from the blower chamber 12 in the left - right direction, the distance between the air inlet 16 and the blower chamber 12 is relatively far. Thus, it is beneficial to reduce the influence of the air flow flowing out of the blower chamber 12 on the temperature of the air flow at the air inlet 16, and it is beneficial for the air flow entering the box body 41 through the air inlet 16 to effectively dissipate heat from the electronic control module 42.

[0068] Reference Figures 1-2 , according to some alternative embodiments of the present utility model, at least part of the air flow inlet 411 is opposite to the air inlet 16 in the left - right direction. For example, part of the air flow inlet 411 is opposite to the air inlet 16 in the left - right direction; for example, the whole air flow inlet 411 is opposite to the air inlet 16 in the left - right direction. At least part of the air flow outlet 412 is opposite to the air flow inlet 411 in the left - right direction. For example, part of the air flow outlet 412 is opposite to the air flow inlet 411 in the left - right direction; for example, the whole air flow outlet 412 is opposite to the air flow inlet 411 in the left - right direction. By making at least part of the air flow inlet 411 opposite to the air inlet 16 in the left - right direction and at least part of the air flow outlet 412 opposite to the air flow inlet 411 in the left - right direction, when the air flow in the external space flows from the air inlet 16 towards the direction of the air flow outlet 412, the air flow encounters less resistance, more air flow can pass through the electronic control module 42, wind loss is reduced, and thus the wind speed is guaranteed and an effective air - cooling effect is achieved.

[0069] Reference Figures 1-2 , according to some alternative embodiments of the present utility model, the air inlet 16 includes a plurality of sub - air inlets arranged side by side in the up - down direction. By forming the air inlet 16 to include a plurality of sub - air inlets arranged side by side in the up - down direction, it is beneficial to improve the structural strength of the side wall of the compressor chamber 13.

[0070] Reference Figures 1-2 , according to some alternative embodiments of the present utility model, a waterproof cover 17 is provided on the outer surface of the side wall. By providing the waterproof cover 17, rainwater and the like can be prevented from entering the electronic control box component 4 through the air inlet 16, thus avoiding safety accidents such as electric leakage. There are a plurality of waterproof covers 17 covering the outside of the sub - air inlets. The number of the waterproof covers 17 is the same as and corresponds to the number of the sub - air inlets one by one. By making the waterproof covers 17 be a plurality and corresponding to the number of the sub - air inlets, it is beneficial to improve the protection performance of the waterproof cover 17. The waterproof cover 17 protrudes from the side wall and defines a wind - guiding cavity between the waterproof cover 17 and the side wall. The wind - guiding cavity communicates the air inlet 16 with the external space. By making the waterproof cover 17 define a wind - guiding cavity communicating the air inlet 16 with the external space between the waterproof cover 17 and the side wall, the obstructive effect of the waterproof cover 17 on the air flow at the air inlet 16 can be reduced.

[0071] ReferenceFigures 1-2 According to some alternative embodiments of the present utility model, a diversion surface 171 is formed on the outer surface of the waterproof cover 17, and the diversion surface 171 extends obliquely away from the air inlet 16 in the direction from top to bottom. By forming the diversion surface 171 on the outer surface of the waterproof cover 17 and making the diversion surface 171 extend obliquely away from the air inlet 16 in the direction from top to bottom, the diversion surface 171 can guide rainwater and the like to flow in a direction away from the air inlet 16, which is beneficial to optimizing the waterproof effect of the waterproof cover 17.

By forming the air flow outlet 412 in the part of the box body 41 located in the fan cavity 12, an effective air pressure difference can be formed between the air flow outlet 412 and the air flow inlet 411 during the operation of the outdoor fan, so that the air flow in the external space can smoothly enter the box body 41 through the air flow inlet 411 to dissipate heat from the electronic control module 42.

By making the first projection and the second projection spaced apart, the part of the box body 41 located in the fan cavity 12 can be prevented from blocking the air outlet 15 and affecting the air outlet effect of the air outlet 15.
