[0038] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0039] Reference below Figure 1-Figure 14 An air conditioner outdoor unit 100 according to an embodiment of the present invention is described.

[0040] The air conditioner outdoor unit 100 is installed outdoors and cooperates with the air conditioner indoor unit to achieve a heat exchange function.

[0041] like Figure 1-Figure 6 As shown, the air conditioner outdoor unit 100 includes: a casing 11, a middle partition 12, a compressor 14, a fan assembly and a heat exchanger 13.

[0042] The casing 11 forms the main appearance of the air conditioner outdoor unit 100. The casing 11 includes: a base 111 and a panel 112. The panel 112 is located on the front side of the air conditioner outdoor unit 100 (the front side refers to the side facing away from the wall when the air conditioner outdoor unit 100 is installed and used, and the side close to the wall is the back). The base 111 and the panel 112 are fixedly connected. The base 111 and the panel 112 can define a storage space for accommodating the compressor 14, the fan assembly and the heat exchanger 13.

[0043] The housing 11 is provided with an outdoor air inlet, which can be provided at the rear side of the housing 11 and at both sides of the housing 11 in the left-right direction. The panel 112 is located on the side of the housing 11 away from the heat exchanger 13, and the panel 112 is provided with an outdoor air outlet. Outdoor air enters the housing 11 from the outdoor air inlet and then enters the room from the outdoor air outlet. The heat exchanger 13 and the fan assembly are located in the housing 11. Outdoor air enters the housing 11 and enters the room from the outdoor air outlet after heat exchange at the heat exchanger 13.

[0044] The panel 112 is connected with an air guide ring 17 , which is arranged opposite to the outdoor air outlet. The air guide ring 17 guides the airflow driven by the fan assembly.

[0045] The middle partition 12 is arranged in the casing 11, the lower side of the middle partition 12 is fixedly connected to the base 111, and the upper side of the middle partition 12 is fixedly connected to the panel 112. The middle partition 12 is arranged in the casing 11, and divides the interior of the casing 11 into a first chamber and a second chamber, the compressor 14 is arranged in the first chamber, and the fan assembly is arranged in the second chamber. The middle partition 12 separates the compressor 14 and the fan assembly so that the compressor 14 and the fan assembly do not interfere with each other.

[0046] The heat exchanger 13 is located in the housing 11. The heat exchanger 13 can be arranged opposite to the outdoor air inlet. Air enters the housing 11 from the outdoor air inlet and exchanges heat with the refrigerant at the heat exchanger 13. Part of the heat exchanger 13, the middle partition 12 and the panel 112 form a first chamber, and another part of the heat exchanger 13, the other side of the middle partition 12 and another part of the panel 112 form a second chamber.

[0047] The compressor 14 is disposed in the first chamber. The compressor 14 is provided with an exhaust port and an air return port. The compressor 14 compresses the refrigerant so that the low-pressure refrigerant becomes a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor 14 from the air return port. After the compressor 14 compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor 14 from the air return port.

[0048] A refrigerant circuit is formed between the compressor 14 and the heat exchanger 13. The airflow outside the casing 11 is introduced into the casing 11 from the outdoor air inlet through the fan assembly, and is output to the outside from the outdoor air outlet after heat exchange in the heat exchanger 13.

[0049] The heat exchanger 13 exchanges heat between the outdoor air and the refrigerant transmitted in the heat exchanger 13. The outdoor air entering the second chamber from the outdoor air inlet flows to the heat exchanger 13 to exchange heat with the refrigerant. The outdoor air enters the casing 11 from the outdoor air inlet and flows to the heat exchanger 13. Since the refrigerant circulates in the heat exchanger 13, the outdoor air exchanges heat with the refrigerant when passing through the heat exchanger 13. The outdoor air after heat exchange flows to the outdoor air outlet and is discharged to the outside from the outdoor air outlet.

[0050] For example, the heat exchanger 13 works as a condenser in cooling mode, so that the decompressed refrigerant absorbs heat from the indoor air and evaporates through the heat exchanger 13. The heat exchanger 13 works as a condenser in heating mode, so that the refrigerant condenses by dissipating heat to the indoor air through the heat exchanger 13.

[0051] The fan assembly is disposed in the second chamber, and the airflow outside the housing 11 is introduced into the second chamber from the outdoor air inlet through the fan assembly, and is output to the outside from the outdoor air outlet after heat exchange through the heat exchanger 13. Driven by the fan assembly, outdoor air enters the housing 11 from the outside and flows to the heat exchanger 13. After the outdoor air exchanges heat with the refrigerant at the heat exchanger 13, the refrigerant is discharged to the outside under the drive of the fan assembly.

[0052] like Figure 2 and Figure 4As shown, the fan assembly includes: a blower and a fan 15, the blower and the fan 15 are transmission connected, the blower drives the fan 15 to rotate, so that outdoor air continuously enters the shell and flows to the heat exchanger 13, so that the outdoor air exchanges heat with the refrigerant at the heat exchanger 13, so as to realize the operation of the air conditioner outdoor unit 100.

[0053] Combination Figure 2-Figure 12 As shown, the air conditioner outdoor unit 100 further includes: an electrical box 21, and the electrical box 21 is fixedly connected to the middle partition 12. The electrical box 21 is transversely arranged inside the casing 11, and the electrical box 21 is located at the inner upper part of the casing 11, and the electrical box 21 can also be fixedly connected to the middle partition 12, and the electrical box 21 can be fixedly connected to the casing 11 and the middle partition 12 by screwing, so as to complete the installation and fixation of the electrical box 21.

[0054] The electrical box 21 is provided with a heat dissipation air inlet 25 and a heat dissipation air outlet 26. Air flows into the electrical box 21 from the heat dissipation air inlet 25 and then flows out from the heat dissipation air outlet 26, which can dissipate heat for the components in the electrical box 21 and facilitate ventilation and heat dissipation of the components in the electrical box 21.

[0055] like Fig. 9 As shown, the air conditioner outdoor unit 100 further includes a circuit board 22, which is disposed in the electrical box 21. The circuit board 22 is connected to the electrical box 21 to fix the circuit board 22 to the electrical box 21.

[0056] The air conditioner outdoor unit 100 further includes a heat sink 23, which is disposed in the electrical box 21, and the heat sink 23 is connected to the circuit board 22, and the heat sink 23 is opposite to the heat dissipation air inlet 25. Specifically, the heat sink 23 is connected to the circuit board 22, and the heat sink 23 is used to dissipate heat from components on the circuit board 22. The heat sink 23 is disposed in the electrical box 21, and the heat sink 23 is opposite to the heat dissipation air inlet 25.

[0057] The air conditioner outdoor unit 100 further includes: a heat dissipation duct 31, one end of which is connected to the air guide ring 17 and the other end of which is connected to the heat dissipation air inlet 25. Specifically, the heat dissipation duct 31 is connected to the air guide ring 17 and the heat dissipation air inlet 25. Under the rotation of the fan 15, the airflow enters the air guide ring 17, flows through the heat dissipation duct 31 and flows to the heat dissipation plate 23. The airflow takes away the heat after passing through the heat dissipation plate 23 under the action of pressure. The high airflow speed dissipates the heat on the surface of the heat dissipation plate 23 in time; the high temperature airflow dissipated is blown into the air again by the fan 15, forming a continuous and strong airflow cycle.

[0058] Specifically, during the rotation of the fan 15, the airflow is blown into the air guide ring 17 from the inside of the housing 11, part of the airflow enters the outdoors from the outdoor air outlet, and the other part of the airflow enters the heat dissipation duct 31 through the connection between the heat dissipation duct 31 and the air guide ring 17. The other part of the airflow flows through the heat dissipation duct 31 to the heat dissipation outlet 26, and then flows to the heat dissipation plate 23. Under the action of wind speed and wind pressure, the airflow passes through the heat dissipation fins on the heat dissipation plate 23 to take away the heat, and forms a continuous heat dissipation airflow, thereby achieving the purpose of continuous cooling.

[0059] Compared with the prior art, the air conditioner outdoor unit 100 has an ideal heat dissipation effect and strong reliability. It is not affected by the ambient temperature and can ensure the cooling effect of the air conditioner for users without attenuation of the cooling capacity, effectively solving the problem of module heating in high temperature environments.

[0060] Therefore, the airflow blown by the fan 15 flows along the heat dissipation duct 31 to the heat dissipation plate 23, dissipates the heat of the heat dissipation plate 23, forms a continuous heat dissipation airflow, realizes continuous cooling of the heat dissipation plate 23, and solves the heating problem of components such as the circuit board 22 in a high temperature environment.

[0061] according to Fig. 9 As shown, the electrical box 21 includes: a box body 211 and a box cover 212. The box body 211 is fixedly connected to the middle partition 12. The box cover 212 is connected to the box body 211 to form a storage space, and the circuit board 22 is arranged in the storage space. Specifically, the box cover 212 is located above the box body 211, and the box cover 212 is covered on the box body 211. The box body 211 and the box cover 212 are connected to form a storage space between the box body 211 and the box cover 212 to accommodate the circuit board 22 and the heat sink 23.

[0062] The box body 211 is provided with a mounting groove 24, the heat sink 23 is arranged in the mounting groove 24, and the mounting groove 24 is connected with the other end of the heat dissipation air duct 31. That is, the mounting groove 24 is located on the side of the box body 211 adjacent to the second chamber, the heat sink 23 is arranged in the mounting groove 24, and the heat sink 23 includes: a plate body and heat dissipation fins, and the plate body and the heat dissipation fins are connected. The plate body is in a rectangular plate shape, and the plate body cover is arranged on the upper edge of the mounting groove 24, and the plate body and the mounting groove 24 form a heat dissipation cavity.

[0063] The heat dissipation fins are connected to the lower side of the plate body, and the heat dissipation fins are accommodated in the heat dissipation cavity. The mounting groove 24 is connected to the other end of the heat dissipation air duct 31, that is, the heat dissipation cavity is connected to the other end of the heat dissipation air duct 31. During the rotation of the fan 15, the airflow blows into the air guide ring 17 from the inside of the housing 11, and a part of the airflow enters the heat dissipation air duct 31 through the connection between the heat dissipation air duct 31 and the air guide ring 17, and enters the heat dissipation cavity. Under the action of wind speed and wind pressure, the airflow passes through the heat dissipation fins on the heat dissipation plate 23 to take away the heat, and forms a continuous heat dissipation airflow, thereby achieving the purpose of continuous cooling.

[0064] Combination Figure 9-12 As shown, the mounting groove 24 includes: a bottom wall 241, the bottom wall 241 is provided with a heat dissipation air inlet 25, and the heat dissipation air inlet 25 extends in the front-to-back direction. Specifically, the box body 211 includes: a bottom plate and a plurality of side plates, and the plurality of side plates are connected to the peripheral side of the bottom plate. The bottom plate is arranged horizontally, and a part of the bottom plate constitutes the bottom wall 241 of the mounting groove 24. The heat dissipation air inlet 25 is provided on the bottom wall 241, and the length direction of the heat dissipation air inlet 25 is the front-to-back direction, and the heat dissipation air inlet 25 corresponds to the other end of the heat dissipation air duct 31.

[0065] The mounting groove 24 also includes: a plurality of side walls 242, the plurality of side walls 242 are connected to the peripheral side of the bottom wall 241, one of the side walls 242 is provided with a heat dissipation outlet 26, and the heat dissipation outlet 26 is connected to the second chamber. Specifically, the plurality of side walls 242 are connected to the peripheral side of the bottom wall 241, so that the mounting groove 24 can form a heat dissipation cavity with the heat dissipation plate 23. A heat dissipation outlet 26 is provided on one of the plurality of side walls 242, and the heat dissipation outlet 26 is located on the side of the mounting groove 24 facing the second chamber, and the heat dissipation outlet 26 is connected to the second chamber, so that the airflow flows from the mounting groove 24 to the second chamber under the rotation of the fan, and finally flows to the outside.

[0066] In some embodiments, a plurality of heat dissipation outlets 26 are disposed on one of the side walls 242, and the plurality of heat dissipation outlets 26 extend in the height direction and are spaced apart in the front-to-back direction. Specifically, the heat dissipation outlets 26 extend in the height direction, and the plurality of heat dissipation outlets 26 are spaced apart in the front-to-back direction on one of the side walls 242.

[0067] In some embodiments, the other side wall 242 is arranged opposite to one of the side walls 242 and is inclined relative to the vertical plane, so that the mounting groove 24 is tapered in the direction away from the heat dissipation air inlet 25. Specifically, the other side wall 242 is arranged on the side of one of the side walls 242 away from the second chamber, and the other side wall 242 is arranged opposite to one of the side walls 242. The vertical plane is a plane composed of the height direction and the front-to-back direction. The length direction of the other side wall 242 is the front-to-back direction, and the width direction is inclined relative to the height direction, that is, the plane where the other side wall 242 is located is inclined relative to the vertical plane.

[0068] Since the other side wall 242 and one of the side walls 242 are arranged opposite to each other, the distance between the other side wall 242 and one of the side walls 242 gradually decreases from bottom to top, so that the mounting groove 24 is tapered in the direction away from the heat dissipation air inlet 25, and the opening 171 of the mounting groove 24 in the direction away from the heat dissipation air inlet 25 gradually decreases. After the airflow flows into the mounting groove 24 from the heat dissipation air duct 31, the opening 171 of the mounting groove 24 near the heat dissipation air inlet 25 is the largest, and the air inlet range of the mounting groove 24 is increased as much as possible, thereby improving the heat dissipation efficiency; after the airflow blows through the heat dissipation plate 23, the mounting groove 24 is tapered, guiding the airflow to flow out from the heat dissipation air outlet 26, improving the fluidity of the airflow, thereby improving the heat dissipation efficiency.

A sub-outlet is provided on the front side of the waterproof part in the front-to-back direction, and the extension plane of the sub-outlet is perpendicular to the extension plane of the heat dissipation outlet 26 to prevent water droplets from entering the electrical box 21 when the fan 15 is pumping water.
