In order to solve the problem of poor heat dissipation capability of the heat generating device 2 in the air conditioner external unit, an air conditioner external unit is proposed in the present utility model, fig. 1 is a schematic structural diagram (a part of a housing is not shown) of the air conditioner external unit under one angle in the embodiment of the present utility model, fig. 2 is a schematic structural diagram (a part of a housing is not shown) of the air conditioner external unit under another angle in the embodiment of the present utility model, fig. 3 is a cross-sectional view at a in fig. 2, as shown in fig. 1 to 3, the air conditioner external unit may include: a housing 1; a heat generating device 2; a heat radiating unit 3 for radiating heat from the heat generating device 2; the fan 4 and the flow guiding unit 5 are arranged in the shell 1, and the fan 4 can introduce air outside the shell 1 into the shell 1 and enable the air to flow from the surface of the heating device 2 and from the surface of the heat radiating unit 3 under the action of the flow guiding unit 5.

In the present application, the heat radiating unit 3 is used to radiate heat from the heat generating device 2, so that the temperature of the heat generating device 2 is reduced. Secondly, the air outside the shell 1 is introduced into the shell 1 by utilizing the fan 4 in the air conditioner outside machine, so that the temperature of the air introduced from the outside of the shell 1 is far lower than that of the air inside the original shell 1, and the air flows through the surface of the heating device 2 and the surface of the heat radiating unit 3 under the action of the flow guiding unit 5, so that the air with lower temperature introduced from the outside of the shell 1 can exchange heat with the heating device 2 and also can exchange heat with the heat radiating unit 3, thereby further improving the heat radiating effect of the heating device 2. Finally, because the air introduced from outside the shell 1 flows through the surface of the heating device 2 and flows through the surface of the heat radiating unit 3, the heat exchange area between the heat radiating unit 3 and the heating device 2 can be increased, the heat exchange effect is effectively improved, and finally the temperature of the heating device 2 is reduced.

In order to better understand the outdoor unit of the air conditioner of the present application, it will be further explained and described below. As shown in fig. 1 to 3, the air conditioner external unit may include a housing 1, a heat generating device 2, a heat radiating unit 3, a blower 4, a flow guiding unit 5, and the like. Wherein, shell 1 is used for holding heating device 2, radiating element 3, fan 4, water conservancy diversion unit 5 and other spare part etc. and plays certain protection and rain-proof effect. The heat generating device 2 may be a device that generates heat when the air conditioning system is in operation, and may be, for example, a control unit in an external machine of the air conditioner, a frequency converter that controls the compressor 8, or the like. Correspondingly, the air conditioner external unit may include: a compressor 8; and a frequency converter electrically connected with the compressor 8.

The heat radiating unit 3 is used to radiate heat to the heat generating device 2, so that the temperature of the heat generating device 2 is lowered. The heat dissipation unit 3 may be a radiator with various structures, and may be closely attached to the heat generating device 2 to achieve efficient heat conduction, or may be a heat conducting material and the heat generating device 2 to achieve efficient heat conduction, and the heat conducting material may be a heat conducting silicone grease or a heat conducting plate with a high heat conductivity coefficient, such as a metal plate, spaced between the heat generating device 2 and the heat dissipation unit 3.

As shown in fig. 1 and 2, a blower 4 is provided inside a housing 1. The air conditioner external unit may include: a heat exchanger capable of communicating with the compressor 8. The fan 4 is used for blowing air to the heat exchanger so as to improve the heat exchange efficiency between the refrigerant and the air in the heat exchanger. Since the blower 4 can generate suction force when operating, the blower 4 can introduce air outside the housing 1 into the interior of the housing 1 and cause the air to flow from the surface of the heat generating device 2 and from the surface of the heat radiating unit 3 by the flow guiding unit 5.

As a possibility, as shown in fig. 1 and 3, the flow guiding unit 5 and the housing 1 can form a bent first flow channel 6, and the fan 4 can introduce air outside the housing 1 into the housing 1 through the first flow channel 6. The heat dissipation unit 3 and the heat generation device 2 are arranged in the first flow channel 6, so that air with low temperature introduced from the outside of the shell 1 can exchange heat with the heat generation device 2 and also can exchange heat with the heat dissipation unit 3, and the heat dissipation effect of the heat generation device 2 is further improved. The end of the first flow passage 6 communicating with the first space 71 is located upstream of the blower 4. With this structure, the suction force generated by the blower 4 when in operation can introduce air outside the housing 1 into the first space 71 upstream of the blower 4 through the first flow passage 6.

The direction in which the air flows at the heat radiating unit 3 is substantially the same as the extending direction of the heat radiating unit 3, as shown in fig. 3, specifically, flows in the vertical direction. The direction in which the air flows at the heat generating device 2 is substantially the same as the extending direction of the heat generating device 2, as shown in fig. 3, specifically, flows in the vertical direction. That is, the air introduced from the first flow path 6 flows through the surface of the heat generating device 2 under the action of the blower 4, is bent under the action of the flow guiding unit 5, and flows through the surface of the heat radiating unit 3. As shown in fig. 1, the air is bent by the deflector unit 5 by an angle of approximately 180 degrees.

As a possibility, the flow guiding unit 5 may comprise a dividing unit, as shown in fig. 1. The partition unit divides the inside of the housing 1 into a first space 71 and a second space 72. The housing 1 forming the second space 72 is provided with an air inlet 11, the second space 72 forms part of the first flow passage 6 communicating with the air inlet 11, the heat generating device 2 is disposed in the second space 72, and the blower 4 is disposed in the first space 71. The first space 71 and the second space 72 communicate through the first flow passage 6. When the blower 4 is operated, air outside the housing 1 is sucked from the air inlet 11, passes through a part of the first flow passage 6 formed by the second space 72, and then enters into the first space 71.

As a possibility, as shown in fig. 1, a substantial part of the heat exchanger may be arranged in the first space 71. The compressor 8 may be disposed in the second space 72. Air outside the housing 1 is sucked from the air inlet 11 and can also dissipate heat from the compressor 8 when passing through the second space 72.

As a possibility, as shown in fig. 1 to 3, the heat generating device 2 and the heat radiating unit 3 may be mounted on a partition unit, and heat exchange between the heat radiating unit 3 and the heat generating device 2 is enabled. The partition unit forms part of the first flow passage 6, and the heat dissipation unit 3 is located in the part of the first flow passage 6 formed by the partition unit. Therefore, the air flowing into the second space 72 outside the housing 1 may enter the first space 71 through a portion of the first flow passage 6 formed by the partition unit, and during this process, the air may flow through the heat dissipation unit 3 to cool the heat dissipation unit 3.

Since the heat generating device 2 and the heat radiating unit 3 are mounted on the partition unit, the heat generating device 2 and the heat radiating unit 3 may be disposed opposite to each other. Specifically, the partition unit has a flow guide member 51 and a plate body 52 at a portion of the first flow passage 6, and a portion of the first flow passage 6 is formed between the flow guide member 51 and the plate body 52, and air flowing between the flow guide member 51 and the plate body 52 flows toward the heat dissipation unit 3 and enters the first space 71 by the flow guide member 51. The plate body 52 has a first opening 521, and a portion of the first flow passage 6 communicates with the second space 72 through the first opening 521. The heating device 2 and the heat dissipation unit 3 may be fixedly connected to the plate 52 of the separation unit, the heating device 2 is fixedly connected to a surface of the plate 52 facing the second space 72, and the heat dissipation unit 3 is fixedly connected to a surface of the plate 52 facing the flow guide member 51. The plate 52 may have a hollow structure, so that the heat dissipating unit 3 directly contacts the heat generating device 2 to conduct heat through the hollow structure, or the heat dissipating unit 3 conducts heat with the heat generating device 2 through a heat conducting material. This reduces a layer of the heat-conducting medium, i.e., the plate body 52, and improves the heat-conducting efficiency between the heat-generating device 2 and the heat-radiating unit 3.

As shown in fig. 1, the air inlet 11 and the first opening 521 may be staggered in the vertical direction, so that the heat generating device 2 is located between the first opening 521 and the air inlet 11 in the vertical direction, so that the air flowing through the air inlet 11 and the first opening 521 can be ensured to flow through the heat generating device 2 to the greatest extent, so as to improve the heat dissipation effect of the heat generating device 2.

As a possibility, as shown in fig. 3, the heat generating device 2 may include a circuit board in a plate shape with a gap between the circuit board and the heat dissipating unit 3 or with the board body 52, and by this gap, the surface of the circuit board facing the heat dissipating unit 3 may also be efficiently dissipated. Meanwhile, the part of the surface of the circuit board facing the heat radiating unit 3 can adopt a heat conducting material to conduct efficient heat transfer with the heating device 2, so that the heat of the circuit board is transferred to the heat radiating unit 3. The portion may be the most heated area of the circuit board.

As a possible implementation, fig. 4 is a schematic structural diagram of a heat dissipating unit in a first embodiment of the present utility model, fig. 5 is a schematic structural diagram of a heat dissipating unit in a second embodiment of the present utility model, fig. 6 is a schematic structural diagram of a heat dissipating unit in a second embodiment of the present utility model, the fin portions of the heat dissipating unit are not shown in the second embodiment, fig. 7 is a schematic structural diagram of a heat dissipating unit in a third embodiment of the present utility model, and as shown in fig. 4 to 7, the heat dissipating unit 3 may include: a heat sink 31. The heat sink 31 may include a bottom plate 311 and a plurality of fin portions 312 having intervals between adjacent ones, and passages for air to flow through are formed between the adjacent fin portions 312, and extend in the same direction as the first flow passage 6 at the heat radiating unit 3. Through the above structure, when the air flows through the first flow passage 6, the air can flow through the passage, so that the heat exchange efficiency between the air and the fin portion 312 can be improved, thereby improving the cooling degree of the air to the heat dissipation member 31.

Wherein the bottom plate 311 can be thermally conductive to the heat generating device 2. The bottom plate 311 may also be thermally conductive with the heat generating device 2 via a thermally conductive material. The bottom plate 311 may be attached to the plate 52, and the plate 52 may be attached to the heat generating device 2 for heat conduction, or the plate 52 may be attached to the heat generating device 2 for heat conduction via a heat conducting material.

As a practical matter, a plurality of fin portions 312 with spaces between adjacent ones are located on the bottom plate 311 side. Under the action of the flow guiding structure, air flowing through the interval between the flow guiding piece 51 and the plate body 52 flows towards one end of the fin portion 312, which is close to the bottom plate 311, and the bottom plate 311 in the heat radiating unit 3, so that the flow speed of the air can be increased, the heat radiating capacity of the area, which is relatively higher in temperature, of the bottom plate 311 and one end of the fin portion 312, which is close to the bottom plate 311, is increased, and the overall heat radiating effect of the heat radiating unit 3 is further improved.

As a possibility, the heat dissipation unit 3 may include: at least one heat pipe 32.

In one possible embodiment, as shown in fig. 4 and 6, at least one first groove 3111 is provided on the other side (the side where the fin portion 312 is not provided) of the bottom plate 311, and the heat pipe 32 is provided in the first groove 3111. The heat pipe 32 can rapidly spread the received heat locally at the other side of the bottom plate 311 to the area covered by the other heat pipe 32 at the other side of the bottom plate 311, thereby improving the heat dissipation capacity of the heat dissipation unit 3. Further, at least part of the heat pipe 32 may be in thermal conduction with the heat generating device 2, or at least part of the heat pipe 32 may be in thermal conduction with the heat generating device 2 through a heat conducting material. By the structure, the heat on the heating device 2 can be quickly and efficiently transferred to the heat pipe 32, so that the heat pipe 32 can quickly diffuse the received heat to the area covered by other heat pipes 32 on the other side of the bottom plate 311.

In another possible embodiment, as shown in fig. 5 to 7, at least one second groove 3112 is formed at the bottom plate 311, or at least one first opening is formed at an end of the fin portion 312 near the bottom plate 311, at least one second opening 3121 is formed at an end of the fin portion 312 far from the bottom plate 311, one end of the heat pipe 32 is disposed in the second groove 3112 or the first opening, and the other end of the heat pipe 32 is inserted into the second opening 3121. When heat is dissipated by the heat dissipating unit 3, heat is generally exchanged between the bottom plate 311 and the heat generating device 2, and therefore, the temperature at the bottom plate 311 is highest. The fin portions 312 exchange heat with the bottom plate 311, thereby helping the bottom plate 311 to dissipate heat. Since the temperature of the region of the fin portion 312 away from the bottom plate 311 is relatively low compared to the temperature of the region close to the bottom plate 311, the heat dissipation amount of the region of the fin portion 312 away from the bottom plate 311 is low, and thus, it is not fully utilized. Since the heat pipe 32 has a strong heat conduction property, it can transfer a large amount of heat at the bottom plate 311 or at the end of the fin portion 312 close to the bottom plate 311 to the area of the fin portion 312 away from the bottom plate 311 to reduce the temperature at the bottom plate 311 or at the end of the fin portion 312 close to the bottom plate 311, the heat dissipation capacity of the area of the fin portion 312 away from the bottom plate 311 can be greatly improved, and in general, the heat dissipation performance of the entire heat dissipation unit 3 can be further improved, so that the heat generating device 2 can be reduced to a lower temperature.

In the above embodiment, as shown in fig. 5 to 7, the first opening or the second groove 3112 is opened in the arrangement direction of the fin portions 312, the second opening 3121 is opened in the arrangement direction of the fin portions 312, and the other end of the heat pipe 32 is inserted into the second opening 3121 of the plurality of fin portions 312. With the above structure, the contact area between the heat pipe 32 and the fin portion 312 can be ensured, so that the heat exchange efficiency between the heat pipe 32 and the fin portion 312 can be improved. In addition, the heat pipe 32 can be easily bent, and the heat pipe can be ensured to transfer a large amount of heat at the bottom plate 311 or at one end of the fin portion 312 close to the bottom plate 311 to the region of the fin portion 312 far from the bottom plate 311 only by being bent into a U shape.

When the heat pipes 32 are plural, as shown in fig. 5 to 7, the heat pipes 32 may be concentrated at one end of the second groove 3112 or the first opening, and the heat pipes 32 may be dispersed at one end of the second opening 3121. The heat pipe 32 is located in the area of the bottom plate 311 corresponding to the area where one end of the second groove 3112 or the first opening is intensively distributed and is attached to the heat generating device 2 for heat conduction, or is thermally conducted with the heat generating device 2 through a heat conducting material, so that the temperature of the area of the corresponding bottom plate 311 is highest, and heat in the area needs to be efficiently transferred to other areas for heat dissipation.

The application also provides an air conditioning system which can comprise the air conditioner external unit. The air conditioning system can also comprise an air conditioning inner machine, and the air conditioning inner machine is used for receiving the refrigerant compressed by the compressor 8 in the air conditioning outer machine and conveying the utilized refrigerant back to the air conditioning outer machine.
