Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a wind-shielding vertical plate, an outdoor unit and an air conditioner that are beneficial to the heat dissipation of a compressor. Background Art

[0002] The windproof plate is a structure used to separate the compressor from other components in the air conditioner. The compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit.

[0003] In the prior art, when the air conditioner is running, the exhaust temperature is often high, and the compressor lubricating oil is easily degraded due to high temperature, which affects the service life of the compressor. In order to increase the service life of the compressor, designers often intentionally control the compressor exhaust temperature during development, but this affects the performance of the air conditioner.

[0004] Usually, the outdoor unit condenser of the air conditioner adopts forced heat exchange by air cooling to take away the heat of the condenser. The compressor adopts refrigerant heat dissipation, which has limited heat dissipation capacity. The compressor and the surrounding air adopt natural heat exchange, which has poor heat exchange effect. Summary of the invention

[0005] The purpose of the present application is to provide a wind-shielding vertical plate, an outdoor unit and an air conditioner that are beneficial to the heat dissipation of a compressor, so as to solve the problem of poor heat dissipation effect of the compressor when working in the prior art.

[0006] Therefore, in the first aspect of the present application, a wind shielding plate is provided that is beneficial to the heat dissipation of the compressor, and an air inlet and an air outlet are provided on the wind shielding plate; the wind shielding plate is bent and semi-encloses the compressor, a part of the wind shielding plate is located on the left side of the compressor, and the other part of the wind shielding plate is located on the rear side of the compressor; the air inlet is arranged on the rear surface of the wind shielding plate, and the air outlet is arranged on the left surface of the wind shielding plate.

[0007] The present application provides a wind-shielding vertical plate that is beneficial to the heat dissipation of the compressor. During use, the compressor generates heat and transfers the heat to the air in the cavity where the compressor is located, and the temperature of the air in the cavity where the compressor is located increases; when the fan is running, the air inside the cavity where the fan is located is discharged to the outdoors, and the air pressure in the cavity where the fan is located decreases. The air pressure in the cavity where the fan is located is lower than the air pressure in the cavity where the compressor is located. The hot air in the cavity where the compressor is located is sucked into the cavity where the fan is located from the air outlet, and the air pressure in the cavity where the compressor is located also decreases accordingly; the air pressure in the cavity where the compressor is located is lower than the air pressure near the condenser. The temperature of the air decreases after contacting the condenser, and a part of the cooled air is directly sucked into the cavity where the fan is located after being cooled. The other part of the cold air is sucked into the cavity where the compressor is located from the air inlet; after the cold air enters the cavity where the compressor is located, it contacts the compressor, absorbs the temperature of the compressor, realizes heat exchange with the compressor, reduces the temperature of the working environment of the compressor, and thus reduces the temperature of the compressor when working; the cold air entering the cavity where the compressor is located absorbs the heat of the compressor and is sucked into the cavity where the fan is located from the air outlet, and the fan then discharges the air sucked from the air outlet to the outdoors, and such a cycle can continuously renew the cold air in the cavity where the compressor is located, realize continuous cooling of the compressor, and enhance the heat dissipation effect of the compressor when working; compared with the prior art, this embodiment does not need to intentionally control the exhaust temperature of the compressor, so as to avoid negative impact on the performance of the air conditioner.

[0008] In a possible implementation manner of the first aspect of the present application, the height difference between the air inlet and the air outlet is 0 to 10 cm.

[0009] Through the above-mentioned possible implementation manner of the first aspect of the present application, the air inlet and the air outlet are located at approximately the same height, cold air flows in from the air inlet, absorbs the heat of the compressor and heats up after contacting the compressor, and the heated hot air flows out from the air outlet to form a heat exchange channel. Compared with the situation where the height difference between the air outlet and the air inlet is large, this implementation manner can reduce the turbulence of the air flow inside the cavity where the compressor is located, and the air flow between the air inlet and the air outlet can be smoother and more stable, and the flow direction is not easily deflected, thereby reducing the retention of cold air in the cavity where the compressor is located after contacting the compressor, and continuously and timely updating the cold air in the cavity where the compressor is located, thereby improving the heat exchange efficiency, and reducing the air temperature in the cavity where the compressor is located, thereby reducing the temperature of the compressor when it is working. When the height of the air inlet and the air outlet are equal, cold air flows in from the air inlet, absorbs the heat of the compressor and heats up after contacting the compressor, and the heated hot air flows out from the air outlet to form a heat exchange channel. The heat exchange channel is almost parallel to the horizontal plane. Compared with the situation where the air outlet and the air inlet are at different heights, this embodiment can reduce the turbulence of the air flow inside the cavity where the compressor is located, and the air flow between the air inlet and the air outlet can be smoother and more stable, and the flow direction is not easily deflected, thereby reducing the retention of cold air in the cavity where the compressor is located after contacting the compressor, and continuously and timely updating the cold air in the cavity where the compressor is located, thereby improving the heat exchange efficiency, and reducing the air temperature in the cavity where the compressor is located, thereby reducing the temperature of the compressor when it is working.

[0010] In a possible implementation manner of the first aspect of the present application, the wind-shielding vertical plate is provided with heat dissipation holes, and the heat dissipation holes are located at the top of the compressor and / or the bottom of the compressor.

[0011] In a possible implementation manner of the first aspect of the present application, the air inlet and the air outlet are located in the middle of the compressor and / or the upper middle part of the compressor and / or the lower middle part of the compressor.

[0012] Through the above possible implementation methods of the first aspect of the present application, the heat emitted by the compressor causes the air in the cavity where the compressor is located to heat up, and the heated hot air forms convection with the cold air outside the cavity where the compressor is located through the heat dissipation holes. At the same time, the heat radiation generated by the compressor transmits the heat to the outside of the cavity where the compressor is located through the heat dissipation holes, thereby enhancing the heat dissipation effect of the compressor. The air inlet and the air outlet are arranged in the lower middle part and / or the middle part and / or the upper middle part of the compressor. When multiple groups of air inlets and air outlets are respectively arranged in the middle, lower middle part and upper middle part of the compressor, multiple groups of air flow channels can be formed in the middle, lower middle part and upper middle part of the compressor respectively. The airflow formed between the air inlet and the air outlet cools the area between the upper and lower ends of the compressor. The top and bottom of the compressor are far away from the air inlet and the air outlet. The airflow formed between the air inlet and the air outlet cannot drive the air flow at the top and bottom of the compressor, and the top and bottom of the compressor will also generate heat. Since the heat dissipation holes are distributed at the top and bottom of the compressor, therefore, The hot air at the top and bottom of the compressor convects with the cold air outside the cavity where the compressor is located through the heat dissipation holes. The heat dissipation holes form a ventilation hole group at the top or bottom of the wind-proof vertical plate, forming multiple groups of heat exchange channels to achieve simultaneous heat exchange at multiple locations, reduce the air temperature at the top and bottom of the compressor, and thus cool the top and bottom of the compressor; at the same time, it can also increase the flow rate of air entering the cavity where the compressor is located, so that more air flows into the cavity where the compressor is located, increase the air renewal efficiency inside the cavity where the compressor is located, reduce the amount of heated air retained in the cavity where the compressor is located, and shorten the retention time of heated air in the cavity where the compressor is located. The air inlet and the air outlet form a continuous circulating airflow channel near the middle of the compressor to achieve heat exchange in the middle of the compressor. When the pressure difference near the two ports of the heat dissipation hole changes, the cold and hot air flows reciprocate through the heat dissipation hole for heat exchange, thereby exchanging heat at the bottom of the compressor.

[0013] In a possible implementation manner of the first aspect of the present application, the area of ​​the air inlet and / or the area of ​​the air outlet is 4 to 50 cm 2 .

[0014] Through the above-mentioned possible implementation methods of the first aspect of the present application, an area of ​​the air inlet and / or the air outlet that is too small or too large will affect the flow rate and smoothness of the air flow in the heat exchange channel. For example, if the area of ​​the air outlet is too small, only the air near the air outlet will be sucked into the cavity where the fan is located, and the air flowing from the air inlet into the cavity where the compressor is located cannot be quickly sucked away and diffused to fill the entire space of the cavity where the compressor is located, resulting in the air in the cavity where the compressor is located being still distributed at various positions after being heated up, and the hot air located far away from the air outlet cannot be sucked away in time, and a continuous and smooth airflow cannot be formed between the air inlet and the air outlet, which prolongs the residence time of the hot air in the cavity where the compressor is located, thereby reducing The heat exchange efficiency is improved; if the air inlet area is too small, the velocity of the cold air sucked into the cavity where the compressor is located from the air inlet is large but the flow rate is small, and a stable airflow cannot be formed inside the cavity where the compressor is located. The cold air diffuses to other positions in the cavity where the compressor is located, resulting in the cold air being unable to be discharged in time after being heated, and a continuous and stable airflow cannot be formed between the air inlet and the air outlet, which prolongs the residence time of the hot air in the cavity where the compressor is located, thereby reducing the heat exchange efficiency; therefore, in this embodiment, the area of ​​the air inlet and / or the area of ​​the air outlet are appropriately set to 4-50cm according to the relationship between the cavity where the fan is located, the cavity where the compressor is located, and the air pressure outside the casing when the outdoor unit is in the working state. 2 , which can effectively improve the continuity and stability of the airflow between the air inlet and the air outlet.

[0015] In a possible implementation manner of the first aspect of the present application, the rear surface of the wind-blocking vertical plate has a curved surface portion, and the air inlet is arranged on the curved surface portion.

[0016] In a possible implementation manner of the first aspect of the present application, the air inlet and / or the air outlet is polygonal or circular.

[0017] In the second aspect of the present application, an outdoor unit of an air conditioner is provided, comprising a casing, a fan and a compressor, and also comprising the wind-blocking plate that facilitates heat dissipation of the compressor as described in the first aspect of the present application, the wind-blocking plate dividing the internal space of the casing into a first cavity and a second cavity, the compressor being located in the first cavity, and the fan being located in the second cavity.

[0018] In a third aspect of the present application, an air conditioner is provided, comprising an outdoor unit of the air conditioner in the second aspect of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] As described in the background technology, in the prior art, when the air conditioner is running, the exhaust temperature is often high, and the lubricating oil of the compressor 300 is easily degraded due to high temperature, which affects the service life of the compressor 300. In order to increase the service life of the compressor 300, the designers often intentionally control the exhaust temperature of the compressor 300 during development, but this affects the performance of the air conditioner. Usually, the condenser 200 of the air conditioner outdoor unit adopts air-cooled forced heat exchange to take away the heat of the condenser 200. The compressor 300 adopts refrigerant heat dissipation, and the heat dissipation capacity is limited. The compressor 300 and the surrounding air adopt natural heat exchange, and the heat exchange effect is poor.

[0038] In order to solve the above technical problems, in the first embodiment of the present application, a wind-shielding vertical plate is provided to facilitate the heat dissipation of the compressor, such as Figure 1 and Figure 2 As shown, an air inlet 110 and an air outlet 120 are provided on the wind-shielding plate 100; an air inlet 110 and an air outlet 120 are provided on the wind-shielding plate 100; the wind-shielding plate 100 is bent and semi-encloses the compressor 300, a part of the wind-shielding plate 100 is located on the left side of the compressor 300, and another part of the wind-shielding plate 100 is located on the rear side of the compressor 300; the air inlet 110 is arranged on the rear surface of the wind-shielding plate 100, and the air outlet 120 is arranged on the left surface of the wind-shielding plate 100. During use, the compressor 300 generates heat and transfers heat to the air in the cavity where the compressor 300 is located, and the temperature of the air in the cavity where the compressor 300 is located increases; when the fan 400 is running, the air in the cavity where the fan 400 is located is discharged to the outside, and the air pressure in the cavity where the fan 400 is located is reduced. The air pressure in the cavity where the fan 400 is located is lower than the air pressure in the cavity where the compressor 300 is located. The hot air in the cavity where the compressor 300 is located is sucked into the cavity where the fan 400 is located from the air outlet 120, and the air pressure in the cavity where the compressor 300 is located also decreases accordingly; the air pressure in the cavity where the compressor 300 is located is lower than the air pressure near the condenser 200, and the temperature of the air decreases after contacting the condenser 200. A part of the cooled air is directly sucked into the cavity where the fan 400 is located, and another part of the cooled air is sucked out from the air inlet 1 10 is sucked into the cavity where the compressor 300 is located; after the cold air enters the cavity where the compressor 300 is located, it contacts the compressor 300, absorbs the temperature of the compressor 300, realizes heat exchange with the compressor 300, reduces the temperature of the working environment of the compressor 300, and thus reduces the temperature of the compressor 300 when it is working; the cold air entering the cavity where the compressor 300 is located absorbs the heat of the compressor 300 and is sucked into the cavity where the fan 400 is located from the air outlet 120, and the fan 400 then discharges the air sucked from the air outlet 120 to the outdoors, and in this way, the cold air in the cavity where the compressor 300 is located is continuously renewed, the compressor 300 is continuously cooled, and the heat dissipation effect of the compressor 300 is enhanced when it is working; compared with the prior art, the present embodiment does not need to intentionally control the exhaust temperature of the compressor 300, so as to avoid negative impact on the performance of the air conditioner.

[0039] Figure 2The arrow marked with S in the middle indicates the air flow path. The air flow S100 flows through the condenser 200 and enters the cavity where the fan 400 is located. Under the rotation of the fan 400, S100 is divided into S110 and S130. S130 is directly blown out to the outside. S110 is sucked into the cavity where the compressor 300 is located from the air inlet 110. S110 is divided into S111 and S112 in the cavity where the compressor 300 is located. S111 and S112 bypass the compressor 300 respectively and then merge at the air outlet 120 to form S120. S120 is sucked into the cavity where the fan 400 is located from the air outlet 120 and merges with S130. S120 sucked into the cavity where the fan 400 is located is blown out to the outside under the rotation of the fan 400.

[0040] In a possible implementation of Example 1 of the present application, as Figure 3 and Figure 4 As shown, the height difference between the air inlet 110 and the air outlet 120 is 0 to 10 cm. The air inlet 110 and the air outlet 120 are located at approximately the same height. The height refers to the vertical distance between the structure and the ground when the outdoor unit is in working condition. For example, the height of the air outlet 120 is h1, and the height of the air inlet 110 is h2. The absolute value of h1-h2 is 0 to 10 cm. Cold air flows in from the air inlet 110, and after contacting with the compressor 300, it absorbs the heat of the compressor 300 and heats up. The heated hot air flows out from the air outlet 120, forming a heat exchange channel (channel refers to the path through which the air flows). Relative to the air outlet 120, the air inlet 110 is located at a height of 0 to 10 cm. 0 and the air inlet 110 have a large height difference, the present embodiment can reduce the turbulence of the air flow inside the cavity where the compressor 300 is located, and the air flow between the air inlet 110 and the air outlet 120 can be smoother and more stable, and the flow direction is not easily deflected, thereby reducing the retention of cold air in the cavity where the compressor 300 is located after contacting the compressor 300, and continuously and timely updating the cold air in the cavity where the compressor 300 is located, thereby improving the heat exchange efficiency, and reducing the temperature in the cavity where the compressor 300 is located, thereby reducing the temperature of the compressor 300 when it is working.

[0041] In a possible implementation of the first embodiment of the present application, the height of the air inlet 110 is equal to that of the air outlet 120, that is, h1=h2. The height of the air inlet 110 is equal to that of the air outlet 120, and the cold air flows in from the air inlet 110, absorbs the heat of the compressor 300 after contacting with the compressor 300, and the heated hot air flows out from the air outlet 120 to form a heat exchange channel, and the heat exchange channel is almost parallel to the horizontal plane. Compared with the case where the air outlet 120 and the air inlet 110 are at different heights, this implementation can reduce the turbulence of the air flow inside the cavity where the compressor 300 is located, and the air flow between the air inlet 110 and the air outlet 120 can be smoother and more stable, and the flow direction is not easily deflected, reducing the retention of the cold air in the cavity where the compressor 300 is located after contacting the compressor 300, and continuously and timely updating the cold air in the cavity where the compressor 300 is located, improving the heat exchange efficiency, and reducing the temperature in the cavity where the compressor 300 is located, thereby reducing the temperature of the compressor 300 when it is working.

[0042] In a possible implementation of Example 1 of the present application, as Figure 5 As shown, a heat dissipation hole 130 is provided on the wind-blocking vertical plate 100. The heat emitted by the compressor 300 heats up the air in the cavity where the compressor 300 is located, and the heated hot air forms convection with the cold air outside the cavity where the compressor 300 is located through the heat dissipation hole 130. At the same time, the heat radiation generated by the compressor 300 transmits the heat to the outside of the cavity where the compressor 300 is located through the heat dissipation hole 130, thereby enhancing the heat dissipation effect of the compressor 300.

[0043] In a possible implementation manner of the first embodiment of the present application, the heat dissipation hole 130 is located at the top of the compressor 300 and / or the bottom of the compressor 300. The air inlet 110 and the air outlet 120 are arranged in the lower middle part and / or the middle part and / or the upper middle part of the compressor 300. When multiple groups of air inlets 110 and air outlets 120 are respectively arranged in the middle, lower middle part and upper middle part of the compressor 300, multiple groups of air flow channels can be formed in the middle, lower middle part and upper middle part of the compressor 300 respectively. The airflow formed between the air inlet 110 and the air outlet 120 cools down the area between the upper and lower ends of the compressor 300. The top of the compressor 300 and the bottom of the compressor 300 are far away from the air inlet 110 and the air outlet 120. The airflow formed between the air inlet 110 and the air outlet 120 cannot drive the air flow at the top and the bottom of the compressor 300, and the top and the bottom of the compressor 300 will also heat up. Due to the heat dissipation hole 130 0 is distributed at the top and the bottom of the compressor 300, so the hot air at the top and the bottom of the compressor 300 convects with the cold air outside the cavity where the compressor 300 is located through the heat dissipation holes 130, forming multiple groups of heat exchange channels, realizing simultaneous heat exchange at multiple locations, reducing the air temperature at the top and the bottom of the compressor 300, thereby cooling the top and the bottom of the compressor 300; at the same time, it can also increase the flow rate of air entering the cavity where the compressor 300 is located, so that more air flows into the cavity where the compressor 300 is located, increasing the air renewal efficiency inside the cavity where the compressor 300 is located, reducing the amount of heated air retained in the cavity where the compressor 300 is located, and shortening the retention time of heated air in the cavity where the compressor 300 is located. The air inlet 110 and the air outlet 120 form a continuous circulating airflow channel near the middle of the compressor 300 to achieve heat exchange in the middle of the compressor 300. When the air pressure difference near the two ends of the heat dissipation hole 130 changes, the cold and hot air flows reciprocally through the heat dissipation hole 130 to perform heat exchange, thereby performing heat exchange on the bottom of the compressor 300.

[0044] In a possible implementation of the first embodiment of the present application, the area of ​​the air inlet 110 and / or the area of ​​the air outlet 120 is 4 to 50 cm 2If the area of ​​the air inlet 110 and / or the air outlet 120 is too small or too large, it will affect the flow rate and smoothness of the air flow in the heat exchange channel. For example, if the area of ​​the air outlet 120 is too small, only the air near the air outlet 120 will be sucked into the cavity where the fan 400 is located, and the air flowing from the air inlet 110 into the cavity where the compressor 300 is located cannot be quickly sucked away and diffused to fill the entire space of the cavity where the compressor 300 is located, resulting in the air in the cavity where the compressor 300 is located still being distributed at various positions after being heated up, and the hot air far away from the air outlet 120 cannot be sucked away in time, and a continuous and smooth airflow cannot be formed between the air inlet 110 and the air outlet 120, which prolongs the time that the hot air stays in the cavity where the compressor 300 is located, thereby reducing the heat exchange efficiency; If the area is too small, the velocity of the cold air sucked from the air inlet 110 into the cavity where the compressor 300 is located is large but the flow rate is small, and a stable airflow cannot be formed inside the cavity where the compressor 300 is located. The cold air diffuses to other positions in the cavity where the compressor 300 is located, resulting in the cold air being unable to be discharged in time after being heated, and a continuous and stable airflow cannot be formed between the air inlet 110 and the air outlet 120, which prolongs the residence time of the hot air in the cavity where the compressor 300 is located, thereby reducing the heat exchange efficiency. Therefore, in this embodiment, the area of ​​the air inlet 110 and / or the area of ​​the air outlet 120 are appropriately set to 4 to 50 cm according to the relationship between the cavity where the fan 400 is located, the cavity where the compressor 300 is located, and the external air pressure of the casing 500 when the outdoor unit is in the working state. 2 , which can effectively improve the continuity and stability of the airflow between the air inlet 110 and the air outlet 120.

[0045] In a possible implementation of the first embodiment of the present application, the circumferential angle of the air inlet 110 and the air outlet 120 around the compressor 300 (eg Figure 2 The angle indicated by α in the figure is greater than or equal to 90 degrees. The circumferential length of the contact surface between the heat exchange channel and the compressor 300 can be increased, the area of ​​the airflow scouring the outer surface of the compressor 300 can be increased, more positions of the compressor 300 can be heat-absorbed, the temperature of the compressor 300 can be reduced, and the heat exchange efficiency can be improved. It should be understood that, in fact, the circumferential angle of the air inlet 110 and the air outlet 120 around the compressor 300 can also be less than 90 degrees.
