[0038] Please refer to Figure 1 , Figure 1 A schematic structural diagram of an air-conditioning outdoor unit 300 provided in an embodiment of the present utility model.

[0039] An embodiment of the utility model provides an air-conditioning system (not shown), which includes an air-conditioning indoor unit and an air-conditioning outdoor unit 300, which are connected by a pipeline to transfer indoor heat to the outdoors, or absorb heat from the outdoors to the indoors, thereby adjusting the indoor temperature and humidity.

[0040] Please refer to Figure 1-Figure 3 , Figure 2 A schematic diagram of the structure of the air guide cover 120 and the electric control box 140 provided in the embodiment of the utility model from a first viewing angle; Figure 3 This is a schematic structural diagram of the air guide cover 120 and the electric control box 140 provided in an embodiment of the utility model from a second viewing angle.

[0041] The air conditioner indoor unit in this embodiment includes an air conditioner unit 200 and a heat dissipation device 100, wherein the heat dissipation device 100 includes a housing 110 and an air guide cover 120; the housing 110 is provided with a receiving cavity 111, and the air conditioner unit 200 is located in the receiving cavity 111. The air guide cover 120 is connected to the housing 110 and is spaced apart from the air conditioner unit 200. It can be understood that the air conditioner unit 200 includes but is not limited to structures such as a compressor, a condenser, an evaporator, and a connecting pipe.

[0042] The air guide cover 120 is provided with a channel 121, and a driver 130 is installed in the channel 121, and the driver 130 is used to drive the air conditioning unit 200 to operate. The channel 121 is connected to the outside, and the channel 121 is isolated from the accommodating chamber 111, so that the accommodating chamber 111 is isolated from the driver 130, so that the substances and structures in the accommodating chamber 111 cannot contact with the driver 130.

[0043] It should be noted that, since the air conditioner outdoor unit 300 needs to take the indoor heat out or bring the outdoor heat into the indoor through the refrigerant; and during the operation of the air conditioner, the compressor in the air conditioner outdoor unit 300 needs to compress the refrigerant, and the refrigerant needs to exchange heat in the condenser and the evaporator, and the connecting pipe is used to transport the refrigerant. It can be understood that the compressor, the condenser, the evaporator and the connecting pipe all contain refrigerant.

[0044] However, some refrigerants are flammable refrigerants. If the compressor, condenser, evaporator and connecting pipes are damaged and cause flammable refrigerant leakage, the flammable refrigerant will come into contact with the driver, causing a safety accident or even an explosion. Therefore, in this embodiment, the driver 130 is isolated from the air conditioning unit 200 by the air guide cover 120, thereby improving the safety of the driver 130.

[0045] In this embodiment, the wind guide cover 120 can allow external gas to flow through the channel 121, so that the air flow can take away the heat of the driver 130 by utilizing the flow of gas in the channel 121 of the wind guide cover 120, thereby dissipating the heat of the driver 130 and improving the heat dissipation effect of the driver 130.

[0046] For further information, please refer to Figure 1-Figure 4 , Figure 4 The schematic diagram of the structure of the air guide cover 120 and the electric control box 140 provided in the embodiment of the utility model from the third perspective. The channel 121 includes an air inlet 125 and an air outlet 126. It can be understood that the gas enters from the air inlet 125, flows through the driver 130, absorbs the heat of the driver 130, and then is discharged through the air outlet 126. As a result, the gas can circulate in the channel 121, thereby driving the heat of the driver 130, dissipating the heat of the driver 130, and improving the heat dissipation effect.

[0047] According to the above structural arrangement, in this embodiment, the channel 121 is a straight channel 121, so that the flow of gas will not be blocked by obstacles, thereby accelerating the flow rate of the gas.

[0048] In other embodiments, the channel 121 may extend in a curved manner, thereby increasing the contact area between the gas and the driver 130 .

[0049] For further information, please refer to Figure 1-Figure 5 , Figure 5 The schematic diagram of the structure of the air guide cover 120 and the electric control box 140 provided in the fourth perspective of the embodiment of the utility model. The heat dissipation device 100 also includes a first pipe 122 and a second pipe 123, and the first pipe 122 and the second pipe 123 are respectively connected to the two ends of the channel 121. It can be understood that the first pipe 122 is connected to the air inlet 125; the second pipe 123 is connected to the air outlet 126.

[0050] The first pipe 122 and the second pipe 123 are both trumpet-shaped. Specifically, the cross-sectional area of ​​the first pipe 122 in a preset direction gradually decreases along the flow direction of the gas; the cross-sectional area of ​​the second pipe 123 in a preset direction gradually increases along the flow direction of the gas. Moreover, the preset direction is perpendicular to the flow direction of the gas.

[0051] Therefore, in this embodiment, by providing the first duct 122 and the second duct 123 , the gas flow rate of the air guide cover 120 is increased, thereby improving the heat dissipation effect on the driver 130 .

[0052] Based on the above, please refer to Figure 1-Figure 5In this embodiment, the heat dissipation device 100 further includes a mounting member 124, which is located at one end of the channel 121. Specifically, the mounting member 124 is located at the air outlet 126. The mounting member 124 is connected to the air guide cover 120 and is used to install a fan, so that the rotation of the fan can accelerate the flow rate of the gas, thereby improving the heat dissipation efficiency.

[0053] In other embodiments, the number and shape of the mounting members 124 can be adjusted according to actual application conditions.

[0054] For further information, please refer to Figure 1-Figure 5 The air conditioner outdoor unit 300 further includes an electric control box 140, which is connected to the housing 110 and the air duct 120; the electric control box 140 is used to accommodate electrical components. It should be noted that the electric control box 140 and the air conditioner unit 200 are respectively located on opposite sides of the air duct 120, and the electrical components are electrically connected to the driver 130, that is, the electrical components are used to control the driver 130, thereby controlling the operation of the refrigeration endurance unit.

[0055] In this embodiment, the length of the electric control box 140 is less than or equal to the distance from the air inlet 125 to the air outlet 126. It can be understood that in this embodiment, the contact area between the air guide cover 120 and the electric control box 140 is large, and the electric control box 140 can be shielded, thereby preventing the flammable refrigerant leaking from the compressor, condenser, evaporator and connecting pipelines from contacting the electrical components in the electric control box 140, thereby improving the safety of the device.

[0056] Based on the above settings, please refer to Figure 1-Figure 7 , Figure 6 A schematic diagram of the structure of the air guide cover 120 provided in an embodiment of the utility model; Figure 7 The schematic diagram of the internal structure of the electric control box 140 provided in the embodiment of the utility model. In the present embodiment, the air guide cover 120 is provided with a first conduction hole 127; the electric control box 140 is provided with a second conduction hole 141; the first conduction hole 127 is directly opposite to the second conduction hole 141; the heat dissipation device 100 further includes a heat dissipation member 150, the heat dissipation member 150 is connected to the electrical component, and at least a part of the heat dissipation member 150 passes through the first conduction hole 127 and the second conduction hole 141 and is located in the channel 121.

[0057] Specifically, the portion of the heat sink 150 located in the electric control box 140 is connected to the electrical components, so that the heat generated by the electrical components during operation can be transferred to the heat sink 150. Subsequently, the heat is transferred from the portion of the heat sink 150 located in the electric control box 140 to the portion located in the air scoop 120, and the heat of the heat sink 150 is taken away by the gas flowing in the air scoop 120, thereby dissipating the heat of the electrical components in the electric control box 140.

[0058] It should be noted that the electric control box 140 includes a support frame, which is connected to the inner wall of the electric control box 140 and the heat sink 150, and is used to support and fix the heat sink 150. In this embodiment, the heat sink 150 is a heat sink.

[0059] Furthermore, in this embodiment, the electric control box 140 also includes a reinforcing rib 142, which is arranged on one side where the electric control box 140 is connected to the air guide cover 120, thereby improving the connection stability between the electric control box 140 and the air guide cover 120, thereby improving the heat dissipation effect on the electrical components.

[0060] In summary, the heat dissipation device 100 protects the driver 130 by arranging the driver 130 in the channel 121 of the air duct 120. In addition, since the channel 121 is isolated from the accommodating chamber 111, the driver 130 will not contact the material or structure in the accommodating chamber 111. The compressor, condenser, evaporator, and connecting pipes in the air conditioner outdoor unit 300 contain flammable refrigerant. When the compressor, condenser, evaporator, and connecting pipes are damaged and cause the flammable refrigerant to leak, the air duct 120 can prevent the leaked flammable refrigerant from contacting the driver 130, thereby avoiding safety accidents and improving safety. The channel 121 of the air duct 120 is connected to the outside world to allow air flow, thereby improving the heat dissipation effect on the driver 130.

[0061] The electric control box 140 contains electric components, which are connected to the part of the heat sink 150 located in the electric control box 140; thus, the electric components can transfer their own heat to the heat sink 150, and the airflow flowing in the air guide cover 120 takes away the heat of the heat sink 150, thereby dissipating the heat of the electric components. In addition, the air conditioner outdoor unit 300 can also use the air guide cover 120 to prevent the flammable refrigerant from contacting the electric components, thereby improving the heat dissipation effect and the safety of the air conditioner outdoor unit 300.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
