[0035] Unless otherwise stated, the term "plurality" means two or more.

[0036] In the prior art, an air conditioner outdoor unit includes a housing and a radiator located in the housing. The radiator includes a base and a plurality of fins arranged on the base. Airflow enters the radiator from one end of the radiator and flows out of the radiator through the other end of the fin after heat exchange with the fin to dissipate heat from the radiator. However, after the air conditioner outdoor unit is installed, the housing is in a closed state and the space is relatively small. After heat exchange with the fin, the airflow cannot flow out from the air outlet of the fin in time. The airflow will partially reflux or even trap the wind, resulting in reduced heat dissipation efficiency of the fin and the radiator.

[0037] Based on this, an embodiment of the present application provides a radiator, including a heat sink and a plurality of fins arranged on the heat sink, and the plurality of fins are arranged to increase the heat dissipation area of ​​the radiator, thereby improving the heat dissipation efficiency of the radiator. At least some of the fins with different heights are arranged in a stepped manner, and the fins with smaller heights are close to the fan of the air conditioner outdoor unit to avoid interference between the fins and the fan of the air conditioner outdoor unit, thereby ensuring the heat dissipation efficiency of the radiator. At the same time, under the premise that the radiator and the fan of the air conditioner outdoor unit do not interfere with each other, the distance between the radiator and the fan of the air conditioner outdoor unit can be made closer, and the air flow blown out by the fan of the air conditioner outdoor unit has a higher flow rate when flowing to the air inlet end of the fin, thereby making the flow rate of the air flow on the fin higher, improving the heat exchange efficiency of the fin, and reducing the backflow of the air flow. At least one guide is provided on the fin to guide the air flow from the air inlet end of the fin to the air outlet end, avoiding the backflow or wind trap of the air flow on the fin, improving the heat exchange efficiency of the air flow and the fin, thereby improving the heat dissipation efficiency of the radiator.

[0038] The embodiments of the present application are described below with reference to the accompanying drawings.

[0039] Reference Figures 1 to 6 As shown, the embodiment of the present application provides a radiator for an outdoor unit of an air conditioner, wherein the radiator 100 comprises: a heat sink 110 and a plurality of fins 120, wherein each fin 120 is arranged at intervals on the heat sink 110, and the heat sink 110 is used to connect with a heating element of the outdoor unit of the air conditioner. At least some of the fins 120 have different heights, and the fins 120 of different heights are arranged in a stepped manner, and the fins 120 of smaller height are close to the fan 200 of the outdoor unit of the air conditioner.

[0040] At least one guide member 121 is disposed on the fin 120 , and the guide member is used to guide the airflow blown out by the fan 200 to flow from the air inlet end of the fin 120 to the air outlet end of the fin 120 .

[0041] The heating element in the outdoor unit of the air conditioner may be an electric control box assembly, and the electric control box assembly includes a computer board bracket 300 and a computer board arranged on the computer board bracket 300 .

[0042] The air inlet end of the fin 120 is arranged on the air outlet side of the fan 200 in the air conditioner outdoor unit. The airflow blown out by the fan 200 of the air conditioner outdoor unit enters the radiator 100 through the air inlet end of the fin 120, and flows out of the radiator 100 through the air outlet end of the fin 120 after heat exchange with the surface of the fin 120 to dissipate heat. The radiator 100 includes a plurality of fins 120, so that the heat exchange area of ​​the radiator 100 is larger, thereby improving the heat dissipation efficiency of the radiator 100. It can be understood that the more the number of fins 120, the larger the heat dissipation area, and the higher the heat dissipation efficiency of the radiator 100. Specifically, the airflow is along the fins 120. Figure 1 Flows in the direction shown by Y.

[0043] For example, the fins 120 are parallel to each other so that the spacing between two adjacent fins 120 is equal everywhere, thereby making the air flow smoother when flowing between two adjacent fins 120. Figure 1 The directions indicated by X are arranged in parallel.

[0044] It is understandable that, since some of the fins 120 are close to the fan 200 of the air conditioner outdoor unit, in order to avoid interference between some of the fins 120 and the fan 200 of the air conditioner outdoor unit, some of the fins close to the fan 200 of the air conditioner outdoor unit are set in a stepped shape, and the fins 120 with smaller heights are close to the fan 200 of the air conditioner outdoor unit, and there is a gap between the fins 120 with smaller heights and the fan 200 of the air conditioner outdoor unit, so as to avoid interference between the fins 120 and the fan 200 of the air conditioner outdoor unit and affect the operation of the fan 200 of the air conditioner outdoor unit. Among them, the height of the fin 120 is the height of the fin 120 at Figure 1 The projection length in the direction shown by Z.

[0045] It should be noted that the guide member 121 can be disposed between two adjacent fins 120 or on the surface of the fin 120 to guide the airflow between two adjacent fins 120 to flow in one direction, and this embodiment does not make any limitation thereto.

[0046] The radiator provided in the embodiment of the present application is arranged in a stepped manner by arranging at least part of the fins 120 near the fan 200 of the air conditioner outdoor unit, and the fins 120 with a smaller height are close to the fan 200 of the air conditioner outdoor unit to avoid interference between the fins 120 and the fan 200 of the air conditioner outdoor unit, thereby ensuring the heat dissipation efficiency of the radiator 100. At the same time, the distance between the fins 120 of the radiator 100 and the fan 200 of the air conditioner outdoor unit can be reduced under the premise that the radiator and the fan of the air conditioner outdoor unit do not interfere with each other. The airflow blown out by the fan 200 of the air conditioner outdoor unit has a higher flow rate when flowing to the air inlet end of the fins 120, thereby making the flow rate of the airflow on the fins 120 higher, improving the heat exchange efficiency of the fins 120, and reducing the airflow backflow. By arranging a plurality of fins 120, the heat dissipation area of ​​the radiator 100 is increased, thereby improving the heat dissipation efficiency of the radiator 100. At least one guide member 121 is provided on the fin 120 to guide the airflow from the air inlet end to the air outlet end of the fin 120, thereby avoiding backflow or wind trapping of the airflow on the fin 120, improving the heat exchange efficiency between the airflow and the fin 120, and thus improving the heat dissipation efficiency of the radiator.

[0047] In some embodiments, the guide member 121 is a groove formed on the fin 120 .

[0048] In this way, by providing the grooves on the fins 120 , the weight of the fins 120 can be reduced while avoiding the backflow of the airflow, and the material required for the fins 120 can be reduced, thereby reducing the cost of the fins 120 .

[0049] In a specific implementation, the flow guide 121 is a Tesla valve channel, which extends along the length direction of the fin 120 , and includes at least two Tesla valves connected end to end.

[0050] The Tesla valve channel runs through the entire fin 120, and the conduction direction of the Tesla valve channel is consistent with the airflow direction on the fin 120, that is, the conduction direction of the Tesla valve channel is Figure 1 The direction shown by Y in the figure is to facilitate the air flow in the Tesla valve channel.

[0051] Specifically, the air inlet end of the Tesla valve slot is connected to the air inlet end of the fin 120, and the air outlet end of the Tesla valve slot is connected to the air outlet end of the fin 120, so that the Tesla valve slot runs through the entire fin 120, so that the airflow can only flow in one direction when flowing through the entire fin 120.

[0052] Reference Figure 4As shown, the airflow enters from the left side of the Tesla valve and is divided into a first branch and a second branch at the first fork 122. The first branch flows from the upper arc branch to the second fork 123, and the second branch flows from the lower straight branch to the second fork 123. The first branch meets the second branch at the second fork 123. At this time, the flow direction of the first branch and the flow direction of the second branch are both toward the right, and the flow directions of the first branch and the second branch are approximately the same. Therefore, the first branch and the second branch will merge at the second fork 123 and continue to flow to the right.

[0053] Reference Figure 5 As shown, the airflow enters from the right side of the Tesla valve and is divided into a third branch and a fourth branch at the third fork 124. The third branch flows from the upper arc branch to the fourth fork 125, and the fourth branch flows from the lower straight branch to the fourth fork 125. The third branch and the fourth branch meet at the fourth fork 125. At this time, the flow direction of the third branch is toward the right, and the flow direction of the fourth branch is toward the left. The flow direction of the third branch is almost opposite to that of the fourth branch. Therefore, the third branch and the fourth branch will generate greater resistance to each other at the fourth fork 125, making it difficult for the third branch and the fourth branch to continue to flow. As a result, the airflow can flow forward in the Tesla valve but is difficult to flow in the reverse direction, so that the airflow can only flow forward in the Tesla valve channel, but cannot flow in the reverse direction.

[0054] In this way, by setting at least one Tesla valve channel on the fin 120, the airflow can only flow along the flow direction of the Tesla valve channel when passing through the fin 120, that is, the airflow can only flow in one direction when passing through the fin 120, thereby avoiding the backflow of the airflow after heat exchange through the fin 120 and avoiding the occurrence of wind traps, thereby improving the heat exchange efficiency between the airflow and the fin 120, and further improving the heat dissipation efficiency of the radiator 100.

[0055] Reference Figure 2 As shown, in some embodiments, the heat sink 110 includes a first heat sink section 111 and a second heat sink section 112 connected to the first heat sink section 111, the first heat sink section 111 is used to face the fan 200, and the second heat sink section 112 is used to connect to the heating element. At least two fins 120 are provided on the first heat sink section 111 and the second heat sink section 112.

[0056] Among them, the heating element of the air conditioner outdoor unit transfers heat to the second heat dissipation section 112, the second heat dissipation section 112 transfers part of the heat to the fins 120 on the second heat dissipation section 112, and the rest of the heat is transferred to the first heat dissipation section 111, the first heat dissipation section 111 transfers the heat to the fins 120 on the first heat dissipation section 111, and the heat is dissipated through the fins 120 on the first heat dissipation section 111 and the fins 120 on the second heat dissipation section 112.

[0057] Exemplarily, the second heat dissipation segment 112 covers at least a portion of the first heat dissipation segment 111 to improve the heat dissipation efficiency of the second heat dissipation segment 112 .

[0058] Specifically, the number of the fins 120 on the first heat dissipation section 111 and the second heat dissipation section 112 is multiple, so as to improve the heat dissipation efficiency of the first heat dissipation section 111 and the second heat dissipation section 112 .

[0059] In this way, the heat of the heating element of the air conditioner outdoor unit is absorbed by setting the second heat dissipation section 112. The first heat dissipation section 111 is set, and the first heat dissipation section 111 is connected to the second heat dissipation section 112, so that the first heat dissipation section 111 absorbs the heat on the second heat dissipation section 112. At least two fins 120 are set on the first heat dissipation section 111 and the second heat dissipation section 112, and the heat is dissipated by the fins 120 to improve the heat dissipation efficiency of the first heat dissipation section 111 and the second heat dissipation section 112.

[0060] In a specific implementation, the first heat dissipation segment 111 and the second heat dissipation segment 112 are integrally formed so that the second heat dissipation segment 112 transfers heat to the first heat dissipation segment 111 .

[0061] Furthermore, the first heat dissipation section 111 , the second heat dissipation section 112 and the fins 120 are integrally formed, so that the structural strength of the heat sink 100 is high and not easily deformed, and at the same time it is beneficial to the heat transfer between the first heat dissipation section 111 , the second heat dissipation section 112 and the fins 120 .

[0062] Reference Figure 1 and Figure 2 As shown, in a specific implementation, the fins 120 arranged in a stepped manner are located on the first heat dissipation section 111 .

[0063] Among them, the first heat dissipation section 111 is close to the fan 200 of the air conditioner outdoor unit, and at least part of the fins 120 on the first heat dissipation section 111 are arranged in a stepped manner to avoid interference between the fins 120 on the first heat dissipation section 111 and the fan 200 of the air conditioner outdoor unit.

[0064] Reference Figure 2 As shown, in some embodiments, the height of at least some of the fins 120 on the second heat dissipation segment 112 is greater than or equal to the height of the largest fin 120 on the first heat dissipation segment 111 .

[0065] Among them, the second heat dissipation section 112 is connected to the heating element of the air-conditioning outdoor unit, and the fins 120 on the second heat dissipation section 112 are far away from the fan 200 of the air-conditioning outdoor unit, and the possibility of interference with the fan 200 of the air-conditioning outdoor unit is small. Therefore, the height of the fins 120 on the second heat dissipation section 112 is set to be greater than or equal to the height of the fins 120 on the first heat dissipation section 111 to increase the heat exchange area of ​​the fins 120 on the second heat dissipation section 112, thereby increasing the heat dissipation area of ​​the second heat dissipation section 112, improving the heat dissipation efficiency of the second heat dissipation section 112, and then improving the heat dissipation efficiency of the radiator 100.

[0066] Reference Figure 2 and Figure 3 As shown, in a specific implementation, the height of the partial fins 120 on the first heat dissipation section 111 close to the second heat dissipation section 112 and the fins 120 on the second heat dissipation section 112 is relatively large. Therefore, at least two spaced-apart guide members are provided on the partial fins 120 on the first heat dissipation section 111 close to the second heat dissipation section 112 and the fins 120 on the second heat dissipation section 112, so that the coverage area of ​​the guide member 121 on the fin 120 is relatively large, further ensuring that the airflow does not flow back when passing through the fin 120.

[0067] Exemplarily, two Tesla valve grooves are provided on the partial fins 120 on the first heat dissipation section 111 close to the second heat dissipation section 112 and the fins 120 on the second heat dissipation section 112. The two Tesla valve grooves are respectively provided on the upper and lower parts of the fins 120, further increasing the heat exchange area of ​​the fins 120 on the second heat dissipation section 112.

[0068] Reference Figure 2 As shown, in a specific implementation, the spacing between adjacent fins 120 on the first heat dissipation segment 111 is less than or equal to the spacing between adjacent fins 120 on the second heat dissipation segment 112 .

[0069] Among them, the height of the fin 120 with the largest height on the first heat dissipation section 111 is less than or equal to the height of the fin 120 on the second heat dissipation section 112. The height of the fin 120 on the first heat dissipation section 111 is smaller, and the heat exchange area of ​​the fin 120 on the first heat dissipation section 111 is smaller. Therefore, the spacing between adjacent fins 120 on the first heat dissipation section 111 is set to be smaller to increase the number of fins 120 on the first heat dissipation section 111, thereby increasing the heat exchange area of ​​the fin 120 on the first heat dissipation section 111 and ensuring the heat dissipation efficiency of the first heat dissipation section 111.

[0070] Reference Figure 1 and Figure 2As shown, in a specific implementation, the heat sink 110 has a heat absorbing surface 113 and a heat dissipating surface 114 that are arranged opposite to each other, each fin 120 is arranged on the heat dissipating surface 114, and part of the heat absorbing surface 113 is used to abut against the heating element.

[0071] Part of the heat absorbing surface 113 performs heat exchange with the heating element of the air conditioner outdoor unit, absorbs the heat of the heating element of the air conditioner outdoor unit, and then dissipates the heat of the heating element of the air conditioner outdoor unit. The heat dissipation surface 114 is arranged opposite to the heat absorbing surface 113, and the heat absorbing surface 113 can transfer heat to the heat dissipation surface 114, and then transfer heat to each fin 120 through the heat dissipation surface 114.

[0072] In a specific implementation, the guide member 121 is located on at least one side of the fin 120 facing toward or away from the fan 200 .

[0073] The airflow flows between two adjacent fins 120 and performs heat exchange with two adjacent surfaces of the two adjacent fins 120. A guide is provided on at least one of the two opposite surfaces of the fin 120, so that the airflow can only flow in one direction along the guide direction when flowing between the two fins 120, thereby avoiding the airflow from flowing back between the two adjacent fins 120.

[0074] Exemplarily, the flow guide is a Tesla valve channel, the Tesla valve channels on each fin 120 are parallel, and the center line of at least one Tesla valve channel on each fin 120 is located on the same plane.

[0075] Reference Figure 6 As shown, based on the above embodiment, this embodiment provides an air-conditioning outdoor unit, including a shell, an electric control box assembly located in the shell, and a radiator 100 connected to the electric control box assembly.

[0076] The structure of the heat sink 100 has been described in detail in the above embodiments, and will not be described again here.

[0077] Exemplarily, the electrical control box assembly includes a computer board and a computer board bracket 300. The computer board is used to monitor the operating status of the air-conditioning outdoor unit, such as temperature, pressure, current, etc., and control the operation of the air-conditioning outdoor unit according to the monitored data. By monitoring and controlling each component in the air-conditioning outdoor unit, the operating efficiency of the air-conditioning outdoor unit is maximized, thereby reducing the energy consumption of the air-conditioning outdoor unit, reducing operating costs, and extending the life of the air-conditioning outdoor unit.

[0078] The computer board bracket 300 is used to fix the computer board, and the heat sink 110 is connected to the computer board bracket 300. The heat sink 110 and the computer board bracket 300 can be connected by screw connection, snap connection or other connection methods, which is not limited in this embodiment.

[0079] Specifically, the computer board generates heat when it is running. If the temperature of the computer board is too high, the working efficiency of the computer board will decrease, affecting the performance of the air conditioner outdoor unit. Therefore, the radiator 100 is connected to the computer board bracket 300, so that the heat generated by the operation of the computer board can be transferred to the radiator 100 through the computer board bracket 300, thereby reducing the heat of the computer board and preventing the computer board from being too high in temperature.

[0080] The indoor unit of the air conditioner further includes a fan 200, which is located in the housing, and the radiator 100 is located at the air outlet side of the fan 200. The fan 200 delivers the airflow to the air inlet end of the radiator 100, and the airflow enters the radiator 100 from the air inlet end of the radiator 100, and flows out of the radiator 100 through the air outlet end of the radiator 100. In the process of the airflow flowing through the radiator 100, the airflow exchanges heat with the radiator 100 to absorb the heat on the radiator 100, dissipate the heat from the radiator 100, and reduce the temperature of the radiator 100. After the heat is dissipated, the temperature of the radiator 100 is lower than the temperature of the computer board, so that the heat on the computer board can continue to be transferred to the radiator 100, thereby continuously reducing the heat of the computer board and ensuring the working efficiency of the computer board.

[0081] The air conditioner outdoor unit provided in the embodiment of the present application is provided with a radiator 100 on the computer board bracket 300 so as to absorb the heat generated by the operation of the computer board through the radiator 100, thereby ensuring the normal operation of the computer board and avoiding affecting the performance of the air conditioner outdoor unit. By providing a fan 200 on the air inlet side of the radiator 100, a relatively low-temperature airflow is delivered to the radiator 100 through the fan 200, and the radiator 100 is cooled by heat exchange between the airflow and the fins 120 on the radiator 100, thereby ensuring that the temperature of the radiator 100 is always lower than the temperature of the computer board, so that the radiator 100 can continuously absorb the heat of the computer board. By providing at least part of the fins 120 on the radiator 100 in a stepped shape, interference between the fins 120 and the fan 200 is avoided, thereby avoiding affecting the operation of the fan 200 and ensuring the heat dissipation efficiency of the radiator 100. By setting at least one Tesla valve channel on the fin 120 of the radiator 100, the airflow can only flow along the direction of the Tesla valve channel when passing through the fin 120, that is, the airflow can only flow in one direction when passing through the fin 120, thereby avoiding the backflow of the airflow after heat exchange through the fin 120 and avoiding the occurrence of wind traps, thereby improving the heat exchange efficiency between the airflow and the fin 120 and further improving the heat dissipation efficiency of the radiator 100.
