Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to a heat dissipation structure of an air conditioner outdoor unit and an air conditioner. Background Art

[0002] When the outdoor temperature is high and the air conditioner outdoor unit is in cooling operation, the temperature of the controller components and the compressor will be very high, affecting the normal operation of the air conditioner, so it is necessary to dissipate heat and cool the controller components and the compressor.

[0003] At present, there are several structures on the market that reduce the temperature of controller components or compressor cavity: 1. Heat dissipation holes are opened on the partition of the air conditioner outdoor unit. The fan forces convection air into the compressor cavity through the heat dissipation holes and discharges the heat through the wiring port. However, the air pressure in the chamber where the fan is located is lower than that in the compressor cavity, so the heat discharge effect is very poor. 2. The structure of heat dissipation holes is designed next to the electronic controller components, but this structure can only reduce the temperature of a single controller component, and cannot reduce the temperature of the entire electrical box and the compressor cavity, and the cooling efficiency is low. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide an air conditioner outdoor unit heat dissipation structure and an air conditioner, by arranging a deflector on the front panel, so as to lead the wind at the air outlet of the mesh cover into the compressor cavity, forming air circulation and greatly reducing the temperature of the compressor cavity.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A heat dissipation structure of an air conditioner outdoor unit, comprising:

[0007] The outer casing has a front panel at the front, a mesh cover is installed on the front panel, and an air inlet is opened on the front panel;

[0008] A middle partition plate is arranged in the outer casing so as to divide the outer casing into a fan chamber and a compressor chamber, and a plurality of exhaust holes for connecting the fan chamber and the compressor chamber are arranged on the middle partition plate. A fan is arranged in the fan chamber, and the wind blown by the fan is discharged through the mesh cover. An electric control box and a compressor are arranged in the compressor chamber, and an air inlet is communicated with the compressor chamber;

[0009] The air deflector is installed on the front panel, and an air inlet and an air outlet are respectively arranged at two ends of the air deflector, the air inlet is arranged opposite to the mesh cover, and the air outlet is communicated with the air inlet of the front panel.

[0010] In this way, part of the high-speed airflow blown out from the fan cavity of the air conditioner outdoor unit is guided into the compressor cavity through the deflector cover. When the air entering the compressor cavity flows through the electronic control box, it takes away part of the heat, thereby achieving cooling of the compressor cavity.

[0011] Preferably, it further comprises a base, which is fixedly mounted on the front panel, and has an opening corresponding to the air inlet therein, and the air deflector is mounted on the base, and the air outlet of the air deflector is connected to the opening of the base.

[0012] Preferably, a filter screen is provided in the base, and the filter screen is installed at the opening of the base. By providing the filter screen, the air flowing into the compressor cavity is filtered to prevent dust, leaves, mosquitoes, etc. from entering the compressor cavity.

[0013] Preferably, the aperture of the mesh on the filter is not greater than 2.5 mm, so as to achieve a better mosquito-proofing effect.

[0014] Preferably, a rib is protruding from the base, and a plurality of buckles are provided on the rib; a plurality of slots matching the buckles are provided on the cover shell of the air deflector, and the air deflector is installed on the base through the cooperation of the slots and the buckles.

[0015] Preferably, a second partition is provided inside the air deflector, and a channel for connecting the air inlet and the air outlet is provided between the second partition and the cover shell of the air deflector. When a buckle is provided on the side of the rib close to the second partition, a slot matching the buckle is provided on the second partition.

[0016] Preferably, the compressor is installed at the lower part of the compressor cavity, the electric control box is installed at the upper part of the compressor cavity, and the air inlet is located between the compressor and the electric control box. This can prevent heat dissipation failure caused by the silent cotton wrapped outside the compressor blocking the air inlet, and on the other hand, it is more conducive to the air entering the compressor cavity to pass through the electric control box completely.

[0017] Preferably, a heat exchanger is further included, the heat exchanger is arranged inside the outer casing and located at the rear of the outer casing, the electric control box is located in front of the heat exchanger, and the exhaust hole of the middle partition is located between the electric control box and the heat exchanger. In this way, after the air enters the compressor cavity from the air inlet, it first contacts the outer shell of the front of the electric control box. Therefore, the water vapor and dust carried in the air are mainly blocked by the outer shell of the electric control box, and then the air flows around to the rear of the electric control box and flows out through the exhaust hole on the middle partition, thereby preventing the corrosion of the components in the electric control box and improving the life of the components; moreover, the negative pressure near the heat exchanger is relatively large, and setting the exhaust hole near the heat exchanger is more conducive to the discharge of hot air in the compressor cavity.

[0018] Preferably, the air deflector is connected with arc transitions on all sides, thereby reducing the attenuation of air in the air deflector due to turning.

[0019] An air conditioner comprises the above-mentioned heat dissipation structure of an air conditioner outdoor unit.

[0020] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: the utility model, through the air deflector provided on the front panel of the air-conditioning outdoor unit, guides part of the high-speed airflow blown out from the fan cavity of the air-conditioning outdoor unit into the compressor cavity through the air deflector; when the air entering the compressor cavity flows through the electronic control box, part of the heat is taken away, thereby effectively reducing the temperature of the compressor cavity, increasing the upper limit of the high-temperature operation of the machine, and increasing the life of components, especially the life of the components and the compressor in the electronic control box, thereby improving the reliability of the whole machine.

[0035] For the sake of clarity, when placing the air conditioner outdoors, the side close to the wall is the back, and the opposite side is the front.

[0036] like Figures 1 to 7 The heat dissipation structure of an air conditioner outdoor unit shown in the figure comprises:

[0037] The outer casing has a front panel 11 at the front, a mesh cover 12 is mounted on the front panel 11, and an air inlet 13 is opened on the front panel 11;

[0038] A middle partition 2 is arranged in the outer casing so as to divide the outer casing into a fan chamber 101 and a compressor chamber 102. The middle partition 2 is provided with a plurality of exhaust holes 21 for connecting the fan chamber 101 and the compressor chamber 102. A fan 3 is arranged in the fan chamber 101, and the wind blown by the fan 3 is discharged through a mesh cover 12. An electric control box 4 and a compressor 5 are arranged in the compressor chamber 102, and an air inlet 13 is communicated with the compressor chamber 102.

[0039] The air deflector 6 is installed on the front panel 11, and an air inlet 61 and an air outlet 62 are respectively provided at both ends of the air deflector 6. The air inlet 61 is arranged opposite to the mesh cover 12, so that the air deflector 6 is closer to the mesh cover 12, the length of the air deflector 6 is reduced, the air flow loss is reduced, and the heat dissipation effect is improved. The air outlet 62 is connected to the air inlet 13 of the front panel 11.

[0040] When the outdoor unit of the air conditioner is running, the air in the fan cavity 101 is discharged through the mesh cover 12, and part of the air discharged from the fan cavity 101 is guided by the guide cover 6 and enters the compressor cavity 102. When the air entering the compressor cavity 102 flows through the electronic control box 4, part of the heat is taken away, thereby achieving cooling. Because when the outdoor unit of the air conditioner is turned on, the compressor cavity 102 is at a positive pressure relative to the fan cavity 101, therefore, the high-temperature gas in the compressor cavity 102 is discharged to the fan cavity 101 through the exhaust hole 21 of the middle partition 2, thereby achieving air circulation in the compressor cavity 102 and cooling of the compressor cavity 102. The test results show that the peak temperature of the components in the electronic control box 4 is reduced from 93°C to 82°C, and the cooling benefit is obvious.

[0041] In one embodiment, the air deflector 6 is directly fixedly mounted on the front panel 11 .

[0042] In another embodiment, it also includes a base 7, which is fixedly mounted on the front panel 11, and an opening 71 corresponding to the air inlet 13 is provided in the base 7, and the air deflector 6 is mounted on the base 7, and the air outlet 62 of the air deflector 6 is connected to the opening 71 of the base 7.

[0043] In order to prevent dust, leaves, mosquitoes, etc. from entering the compressor chamber 102, Figure 3 As shown, a filter screen 72 is further provided in the base 7 to filter the air flowing into the compressor chamber 102, and the filter screen 72 is installed at the opening 71 of the base 7. Generally speaking, the aperture of the mesh hole of the filter screen 72 is not greater than 2.5 mm, and more preferably, the mesh hole of the filter screen 72 can be set in the form of a shutter.

[0044] In the present invention, the base 7 is provided with a rib 73, and the rib 73 is provided with a plurality of buckles 74; the housing of the air deflector 6 is provided with a plurality of slots 63 adapted to the buckles 74, and the air deflector 6 is installed on the base 7 through the cooperation of the slots 63 and the buckles 74. Of course, the air deflector 6 can also be installed on the base 7 through other detachable forms such as buckles / slots, fasteners, etc. In this way, when a lot of dust and other foreign matter accumulates at the filter 72, the air deflector 6 can be removed and the filter 72 of the base 7 can be cleaned to avoid affecting the air circulation.

[0045] like Figure 4 and Figure 5 As shown, the air deflector 6 is provided with a second partition 64 inside, and a passage 65 for connecting the air inlet 61 and the air outlet 62 exists between the second partition 64 and the cover of the air deflector 6. When a buckle 74 is provided on the side of the rib 73 close to the second partition 64, a slot 63 matching the buckle 74 is provided on the second partition 64. In this way, the second partition 64 and the three surfaces of the upper cover of the air deflector 6 are respectively fitted with the surroundings of the rib 73 on the base 7, and a buckle 74 is respectively provided on the surroundings of the rib 73 on the base 7, and a slot 63 corresponding to the buckle 74 is respectively provided on the second partition 64 and the upper cover of the air deflector 6, so that the air deflector 6 can be stably installed on the base 7.

[0046] like Figure 5 As shown, the air deflector 6 is connected by arc transitions on all sides, thereby reducing the attenuation of air in the air deflector 6 due to turning.

[0047] like Figure 6 As shown, the compressor 5 is installed at the lower part of the compressor cavity 102, the electric control box 4 is installed at the upper part of the compressor cavity 102, and the air inlet 13 is located between the compressor 5 and the electric control box 4. This can prevent the heat dissipation failure caused by the silent cotton wrapped outside the compressor 5 blocking the air inlet 13, and on the other hand, it is more conducive to the air entering the compressor cavity 102 to pass through the electric control box 4 completely.

[0048] like Figure 6 and Figure 7As shown, it also includes a heat exchanger 8, which is arranged in the outer casing and located at the rear of the outer casing, the electric control box 4 is located in front of the heat exchanger 8, and the exhaust hole 21 of the middle partition plate 2 is located between the electric control box 4 and the heat exchanger 8. In this way, after the air enters the compressor chamber 102 from the air inlet 13, it first contacts the outer shell of the front part of the electric control box 4. Therefore, the water vapor and dust carried in the air are mainly blocked by the outer shell of the electric control box 4. Then the air goes around to the rear of the electric control box 4 and flows out through the exhaust hole 21 on the middle partition plate 2, thereby preventing the corrosion of the components in the electric control box and improving the life of the components; moreover, the negative pressure near the heat exchanger 8 is relatively large, and setting the exhaust hole 21 near the heat exchanger 8 is more conducive to the discharge of hot air in the compressor chamber 102
