[0040] Air cooling is typically used to dissipate heat from the electronic components of an air conditioner's outdoor unit. The electronic component's heat sink is placed within the unit's air duct. Airflow passes through the unit's heat exchanger before passing through the electronic component's heat sink, removing heat from the heat sink. When the air conditioner is in cooling mode, the airflow through the heat exchanger is heated, resulting in a higher temperature at the electronic component's heat sink. This poor heat dissipation from the heat sink results in limited heat dissipation from the electronic components of the outdoor unit.

[0041] The present invention provides an air-conditioning outdoor unit 100 .

[0042] See also Figures 1 to 10 In one embodiment of the present utility model, the air-conditioning outdoor unit 100 includes a shell 10, a heat exchanger 50, an electronic control component 30 and a fan 20; the electronic control component 30 is arranged in the shell 10, and the electronic control component 30 has a first air inlet 301, a first air outlet 302 and a heat dissipation duct 310 connecting the first air inlet 301 and the first air outlet 302, the first air inlet 301 is connected to the outside, and the first air outlet 302 is connected to the heat exchange chamber 101; the fan 20 is arranged in the heat exchange chamber 101, and the fan 20 is used to introduce external air into the heat exchange chamber 101 through the heat dissipation duct 310.

[0043] In the present invention, the housing 10 can be formed by sequentially enclosing a front panel, a left panel, a right panel, a top panel, a bottom panel, and a back panel. The housing 10 can be provided with a heat exchange chamber 101 and a compression chamber 102. A compressor 40 is provided in the compression chamber 102, and a fan 20 and a heat exchanger 50 are provided in the heat exchange chamber 101. The heat exchanger 50 is a condenser, which is used to release heat absorbed by the air conditioner indoor unit to the outside. A main air inlet can be provided on the side of the housing 10 away from the compression chamber 102, and a second air outlet 1011 can be provided at the front end of the housing 10. The main air inlet and the second air outlet 1011 can be respectively connected to the heat exchange chamber 101 for the intake and exhaust of air from the heat exchange chamber 101. The fan 20 can be provided as an axial flow impeller. When the air conditioner outdoor unit 100 is operating, the fan 20 creates a negative pressure within the heat exchange chamber 101, drawing air from outside the heat exchange chamber 101 into the heat exchange chamber 101. The air then flows through the heat exchanger 50, removes heat from the heat exchanger 50, and delivers it to the external environment. When the negative pressure draws in the external air into the heat exchange chamber 101, the first air outlet 302 of the electronic control assembly 30 is connected to the heat exchange chamber 101, and the air inside the electronic control assembly 30 flows into the heat exchange chamber 101 under the action of the negative pressure. Since the first air inlet 301 is connected to the external environment, under the action of the negative pressure in the heat exchange chamber 101, the electronic control assembly 30 draws in air from the external environment through the first air inlet 301 and discharges it into the heat exchange chamber 101 through the first air outlet 302. This creates a heat dissipation duct 310 within the electronic control assembly 30, forming an air flow path from the external environment to the heat exchange chamber 101, dissipating heat from the electronic control assembly 30.

[0044] The technical solution of the present invention is to set up an electric control component 30 independent of the heat exchange chamber 101, set a first air inlet 301 and a first air outlet 302 on the electric control component 30, and a heat dissipation duct 310 connecting the first air inlet 301 and the first air outlet 302, and connect the first air inlet 301 with the external environment by connecting the first air outlet 302 with the heat exchange chamber 101. When the fan 20 is running and a negative pressure is formed in the heat exchange chamber 101, an air flow path from the first air inlet 301 to the first air outlet 302 can be formed in the heat dissipation duct 310 of the electric control component 30, and external normal temperature air is introduced to dissipate heat from the interior of the electric control component 30, thereby increasing the heat dissipation effect of the electric control component 30 and avoiding interference of the heat exchanger 50 in the heat exchange chamber 101 with the heat dissipation of the electric control component 30, resulting in poor heat dissipation effect of the electric control component 30.

[0045] See Figure 6 、 Figure 7 、 Figure 8As shown, in an embodiment of the present utility model, the electronic control component 30 includes an electronic control box 31 and an electronic control unit 32 arranged in the electronic control box 31, the electronic control box 31 is provided with the first air inlet 301 and the first air outlet 302, and the heat dissipation duct 310 is formed in the electronic control box 31, and the heat dissipation duct 310 is used to dissipate heat for the electronic control unit 32.

[0046] The electrical control box 31 may include a first half shell and a second half shell, which may be connected by snapping. The first half shell and the second half shell are joined to form a heat dissipation duct 310. The electrical control unit 32 is installed within the electrical control box 31 and placed within the heat dissipation duct 310, where air flow within the heat dissipation duct 310 directly dissipates heat from the electrical control unit 32.

[0047] Of course, in order to improve the heat dissipation effect of the electrical control 32, a radiator 33 can be added to the electrical control 32 to conduct heat from the electrical control 32 by utilizing the better heat conduction performance of the radiator 33. The radiator 33 can be arranged in the heat dissipation duct 310, and the heat from the radiator 33 can be conducted by utilizing the air flow in the heat dissipation duct 310. The specific configuration is as follows:

[0048] Optionally, the electronic control component 30 further includes a heat sink 33 disposed in the heat dissipation duct 310 , and the heat sink 33 is used to dissipate heat from the electronic control component 32 .

[0049] The radiator 33 may be a finned radiator having a heat conducting end and a heat dissipating end. The heat conducting end of the finned radiator is connected to the electrical control unit 32 and is used to dissipate heat generated by the electrical control unit 32. The heat dissipating end of the finned radiator is positioned within the heat dissipation duct 310 and comprises a plurality of spaced fins, with air gaps formed between adjacent fins. The air gaps extend along the length of the heat dissipation duct 310. During operation, the radiator 33 dissipates operating heat from the electrical control unit 32. When a flow path is formed within the heat dissipation duct 310 from the first air inlet 301 to the first air outlet 302, the heat on the radiator 33 is dissipated into the heat exchange chamber 101. Following this, the operating heat of the heat exchanger 50 in the heat exchange chamber 101 is dissipated out of the air conditioner outdoor unit 100.

[0050] In addition, the heat dissipation of the radiator 33 of the electronic control component 30 is performed through the independent heat dissipation duct 310, rather than directly placing the radiator 33 in the compression chamber 102. This can prevent the compressor 40 in the compression chamber 102 from heating up and indirectly heating the radiator 33. In addition, the independent heat dissipation duct 310 can reduce the length of the air flow path passing through the radiator 33, reduce air flow loss, and improve heat dissipation efficiency.

[0051] Continue reading Figure 6 、 Figure 7 、 Figure 8 The electric control box 31 is further provided with a second air inlet 303 communicating with the external environment, and the second air inlet 303 faces the radiator 33 .

[0052] With such a configuration, external air can enter the heat dissipation duct 310 through the second air inlet 303, increasing the air flow in the heat dissipation duct 310. When the second air inlet 303 is directed toward the radiator 33, the air flow passing through the radiator 33 per unit time can be increased, thereby improving the heat dissipation effect of the radiator 33.

[0053] In this embodiment, when the radiator 33 is a finned radiator, the air gaps formed between adjacent fins of the finned radiator 33 face the second air inlet 303. This allows the air flowing into the heat dissipation duct 310 from the second air inlet 303 to flow directly through the air gaps, thereby increasing the contact area between the air entering from the second air inlet 303 and the radiator 33, thereby improving the heat dissipation effect of the air entering from the second air inlet 303.

[0054] Among them, the second air inlet 303 can be towards one end of the radiator 33 close to the first air inlet 301, the second air inlet 303 can also be towards one end of the radiator 33 close to the first air outlet 302, or the second air inlet 303 is set between the two ends of the radiator 33.

[0055] See Figure 6 、 Figure 8 、 Figure 10 As shown, the radiator 33 is extended along the length direction of the heat dissipation duct 310, and the radiator 33 has a first heat dissipation area 331, a second heat dissipation area 332 and a third heat dissipation area 333. The first heat dissipation area 331, the second heat dissipation area 332 and the third heat dissipation area 333 are distributed in sequence from the first air inlet 301 to the first air outlet 302, and the second air inlet 303 faces the second heat dissipation area 332.

[0056] It is understood that when the normal-temperature airflow entering the first air inlet 301 passes through the first heat dissipation zone 331, it removes heat from the first heat dissipation zone 331. The temperature of the normal-temperature airflow entering from the first air inlet 301 increases and flows to the second heat dissipation zone 332. At this time, the normal-temperature airflow entering from the second air inlet 303 mixes with the high-temperature airflow flowing into the second heat dissipation zone 332. The temperature of the mixed airflow decreases compared to the temperature of the high-temperature airflow. The mixed airflow flows through the second heat dissipation zone 332 and the third heat dissipation zone 333, removing heat from the second and third heat dissipation zones 332 and 333, and is discharged from the first air outlet 302. This arrangement allows the entire radiator 33 from the first air inlet 301 to the first air outlet 302 to be blown through, effectively cooling the radiator 33, and thus improving the heat dissipation efficiency of the radiator 33.

[0057] See Figure 10 As shown, optionally, an acceleration channel 311 is further formed in the electric control box 31 , and the acceleration channel 311 connects the second air inlet 303 and the heat dissipation duct 310 , and the inner diameter of the acceleration channel 311 is reduced from the second air inlet 303 to the heat dissipation duct 310 .

[0058] The inner diameter of the acceleration channel 311 can be configured to decrease gradually or in a stepped manner from the second air inlet 303 to the heat dissipation duct 310. Since a stepped decrease in the inner diameter of the acceleration channel 311 increases the wind resistance of the air flowing through the acceleration channel 311, the present invention preferably adopts a gradually decreasing inner diameter of the acceleration channel 311. This configuration allows air to enter the second air inlet 303 through the larger diameter position and then flow into the heat dissipation duct 310 through the smaller diameter position. This accelerates the air as it enters the heat dissipation duct 310, increasing the air flow rate through the radiator 33 and improving the heat dissipation efficiency of the radiator 33.

[0059] Optionally, a compression chamber 102 is further provided in the housing 10, and the compression chamber 102 is provided with a compressor 40 and the electronic control component 30. With this arrangement, by disposing the electronic control component 30 in the compression chamber 102, which is independent of the heat exchange chamber 101, the electronic control component 30 can be independent of the heat exchange chamber 101, and there is no need to provide an additional cavity in the housing 10 for disposing the electronic control component 30, thereby reducing the processing cost of the housing 10.

[0060] Optionally, the shell 10 is provided with a first air port 1021 and a second air port 1022 communicating with the compression chamber 102 , wherein the first air port 1021 is connected to the first air inlet 301 , and the second air port 1022 is connected to the second air inlet 303 .

[0061] Among them, the first air port 1021 can be opened on the side of the shell 10 where the compression chamber 102 is provided, and the second air port 1022 can be set at the top of the shell 10 or at the front end of the shell 10. In this way, the first air inlet 301 can be connected to the first air port 1021, and the second air inlet 303 can be connected to the second air port 1022, so that the compression chamber 102 maintains relative sealing with the external environment, thereby reducing the possibility of dust entering the compression chamber 102.

[0062] See Figure 2 、 Figure 3As shown, the air-conditioning outdoor unit 100 also includes a partition 11 arranged in the shell 10, and the partition 11 is used to separate the heat exchange chamber 101 and the compression chamber 102. The partition 11 is provided with a third air outlet 1023, and the third air outlet 1023 connects the heat exchange chamber 101 and the compression chamber 102, and the first air outlet 302 is connected to the third air outlet 1023.

[0063] The housing 10 has a cavity within it, and a partition 11 is disposed within the cavity, separating the cavity into a compression chamber 102 and a heat exchange chamber 101. This arrangement allows the compression chamber 102 and the heat exchange chamber 101 to be completely separated by the partition 11, with communication between them only through the third air port 1023. This prevents high-temperature airflow within the heat exchange chamber 101 from entering the compression chamber 102, heating the electronic control component 30 and affecting its heat dissipation process.

[0064] The first air vent 1021, the second air vent 1022, and the third air vent 1023 are provided with grilles. This arrangement prevents foreign matter from entering the heat dissipation duct 310 when the air conditioning outdoor unit 100 takes in air through the first air vent 1021 and the second air vent 1022. Furthermore, the grilles provided at the first air vent 1021, the second air vent 1022, and the third air vent 1023 increase the structural strength of the first air vent 1021, the second air vent 1022, and the third air vent 1023, thereby ensuring the overall structural strength of the air conditioning outdoor unit 100.

[0065] Optionally, the grille is detachably mounted on the first air outlet 1021, the second air outlet 1022, and the third air outlet 1023. This allows for easy removal of the grille from the first air outlet 1021, the second air outlet 1022, and the third air outlet 1023 for cleaning. Alternatively, in other embodiments, the grille is integrally formed and mounted on the first air outlet 1021, the second air outlet 1022, and the third air outlet 1023. This is not specifically limited herein.

[0066] See Figure 2 As shown, in this embodiment of the present invention, the compressor 40 is located below the electrical control box 31. This arrangement allows the compressor 40 and heat exchanger 50 to be separated from each other, preventing interference with the operation of the compressor 40 during heat exchange with the heat exchanger 50. Furthermore, the independent placement of the compressor 40 and the electrical control box 31 prevents heat generated by the compressor 40 from affecting the heat dissipation of the radiator 33 within the electrical control box 31.

[0067] See Figure 1 、 Figure 2As shown, the shell 10 is also provided with a main air inlet and a second air outlet 1011 respectively connected to the heat exchange chamber 101, the heat exchanger 50 is located between the main air inlet and the second air outlet 1011, and the fan 20 is located on the side of the heat exchanger 50 close to the second air outlet 1011.

[0068] In the above embodiment, the main air inlet can be provided on the side of the housing 10 away from the compression chamber 102, as well as on the top and bottom of the housing 10. Thus, when the fan 20 is in operation, the fan 20 draws air from the periphery of the housing 10, allowing the heat dissipation duct 310 located on one side of the heat exchange chamber 101 to draw air from the external environment into the heat exchange chamber 101. The air entering the heat exchange chamber 101 flows through the heat exchanger 50 and then flows out through the second air outlet 1011, removing heat from the heat exchanger 50 and achieving heat dissipation in the air conditioner outdoor unit 100. A mesh cover can be provided at the second air outlet 1011 to prevent foreign matter from entering the heat exchange chamber 101.

[0069] The present invention also provides an air conditioner comprising an indoor air conditioner unit and an outdoor air conditioner unit 100. The specific structure of the outdoor air conditioner unit 100 is similar to the above-described embodiments. Since the present air conditioner adopts all the technical solutions of all the above-described embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-described embodiments, which will not be described in detail here. The indoor air conditioner unit is connected to the outdoor air conditioner unit 100 via a refrigerant pipe.

[0070] The air conditioner also includes a throttle valve, and the indoor unit also includes an evaporator. When the air conditioner is operating in cooling mode, the refrigerant in the indoor unit's evaporator absorbs heat from the indoor environment at low pressure and evaporates into gas. This gas then flows through the refrigerant pipe into the compressor 40, where it is compressed by the compressor 40 to form a high-temperature, high-pressure gas. This high-temperature, high-pressure gas then enters the heat exchanger 50 of the outdoor unit 100, where it exchanges heat with the outside air entering the heat exchange chamber 101. It condenses into a high-pressure liquid and then passes through the throttle valve into the indoor unit's evaporator. The refrigerant's pressure decreases at the throttle valve, turning it into a low-pressure mixed gas and liquid state. This process further reduces the refrigerant's temperature. After entering the evaporator, the low-temperature, low-pressure refrigerant absorbs heat from the indoor environment and flows back to the outdoor unit 100, completing the refrigeration cycle.

[0071] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
