[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0035] The present disclosure provides a heat exchanger, which is used in an outdoor unit of an air conditioner. Figures 1 to 4 As shown, the heat exchanger includes a plurality of heat exchange components 100, each heat exchange component 100 includes a heat exchange tube 102 and a heat sink 101, the heat exchange tube 102 is inserted into the heat sink 101, and along the horizontal direction of the air conditioner outdoor unit, the plurality of heat exchange components 100 are connected in sequence, and a fold angle is provided between two adjacent heat exchange components 100, and the angle of the fold angle is adjustable.

[0036] In this optional embodiment, the heat exchange assembly 100 includes a heat exchange tube 102 and a heat sink 101. The heat exchange tube 102 is inserted into the heat sink 101. The heat exchange tube 102 is used to allow the refrigerant to flow. The heat in the refrigerant can be transferred to the outside through the heat exchange tube 102 and the heat sink 101 to achieve heat exchange. There are multiple heat exchange assemblies 100, and a folding angle is provided between two adjacent heat exchange assemblies 100. In this way, the heat sink in the heat exchange assembly 100 can be arranged along the horizontal direction of the air-conditioning outdoor unit, so as to increase the heat exchange area of ​​the heat exchange assembly 100 in the limited horizontal space of the air-conditioning outdoor unit and improve the heat exchange efficiency of the heat exchanger. The folding angle between two adjacent heat exchange assemblies 100 is adjustable. In this way, by setting the folding angle with an adjustable angle, the heat exchanger can be adjusted according to the specifications and shapes of different air-conditioning outdoor units, and the length of the heat exchanger along the horizontal direction of the air-conditioning outdoor unit can be increased or decreased, so as to adapt to different types of air conditioners, improve the versatility of the heat exchanger between different air-conditioning outdoor units, and reduce the production cost of the heat exchanger and the air-conditioning outdoor unit.

[0037] This embodiment reduces the complexity of the shape of each heat exchange component 100 through the design of adjustable folding angle, simplifies the production and manufacturing process, and reduces the production cost compared with the special-shaped heat exchanger. Along the horizontal direction of the air-conditioning outdoor unit, multiple heat exchange components 100 are connected in sequence, so that each heat exchange component 100 can be supported at the bottom of the air-conditioning outdoor unit, reducing the occurrence of stacked installation of multiple heat exchange components 100, simplifying the production and manufacturing process, reducing production costs, and improving the installation stability and reliability of the heat exchange component 100. In addition, multiple heat exchange components 100 are connected in sequence along the horizontal direction of the air-conditioning outdoor unit, reducing the stacked installation of multiple heat exchange components 100, which also facilitates the flow of condensed water on the heat exchange component 100, reduces the accumulation of condensed water on the heat exchange component 100, and even causes frost, thereby improving the stability and reliability of the heat exchanger.

[0038] In some optional embodiments, the heat exchange tube 102 includes multiple sub-tube segments and multiple connecting tube segments. The sub-tube segments are arranged in the heat dissipation plate 101, and the two ends of each connecting tube segment are respectively connected to two adjacent sub-tube segments. The sub-tube segments extend vertically along the air conditioner outdoor unit.

[0039] In this embodiment, the heat exchange tube 102 is inserted into the heat sink 101. The heat exchange tube 102 includes multiple sub-tube segments and multiple connecting tube segments. The sub-tube segment is arranged in the heat sink 101, and the two ends of the connecting tube segment are respectively connected to two adjacent sub-tube segments. In this way, the two ends of the sub-tube segment located in the middle of the heat exchange tube 102 can be connected to the two connecting tube segments respectively, and the two ends of the sub-tube segment can be connected to the corresponding sub-tube segments through the two connecting tube segments, so that multiple connecting tube segments and multiple sub-tube segments are connected in series. The sub-tube segment extends vertically along the outdoor unit of the air conditioner. In this way, multiple sub-tube segments can be inserted back and forth in the heat sink 101 to increase the length of the heat exchange tube 102 in the heat exchange assembly 100 and improve the heat exchange effect of the heat exchange assembly 100.

[0040] A plurality of heat exchange components 100 are connected in sequence along the horizontal direction of the air conditioner outdoor unit, and the sub-pipe section extends vertically along the air conditioner outdoor unit, that is, the heat sink 101 extends vertically along the air conditioner outdoor unit. The connecting pipe section is arranged at the end of the sub-pipe section, that is, at the upper and lower ends of the heat sink 101. This reduces the occurrence of heat exchange pipes 102 interfering with the connection of a plurality of heat exchange components 100, and improves the convenience of heat exchanger production and assembly. The heat exchange component 100 extends vertically along the air conditioner outdoor unit, further facilitating the flow of condensed water along the heat exchange component 100, thereby reducing the occurrence of condensed water remaining on the heat exchange component 100 or even freezing, and improving the stability and reliability of the heat exchanger operation.

[0041] For example, in this embodiment, the vertical direction of the air-conditioning outdoor unit is parallel to the direction of the plumb line, that is, the up and down direction of the air-conditioning outdoor unit, and the transverse direction of the air-conditioning outdoor unit is parallel to the horizontal plane. The transverse direction of the air-conditioning outdoor unit can be the front and back direction of the air-conditioning outdoor unit, or the left and right direction of the air-conditioning outdoor unit. No specific limitation is made here, as long as the heat exchange component 100 can be extended vertically.

[0042] In some optional embodiments, such as Figures 1 to 3 As shown, the plurality of heat exchange components 100 include a first heat exchange component 110 and a second heat exchange component 120. The first heat exchange component 110 includes a first heat dissipation plate 111. The second heat exchange component 120 includes a second heat dissipation plate 121, and along the lateral direction of the air conditioner outdoor unit, a first side wall 1111 of the first heat dissipation plate 111 and a second side wall 1211 of the second heat dissipation plate 121 are arranged opposite to each other, a first side edge portion of the first side wall 1111 is connected to a second side edge portion of the second side wall 1211, and the first side edge portion and the second side edge portion can rotate relative to each other.

[0043] In this embodiment, the first side wall 1111 of the first heat sink 111 is arranged opposite to the second side wall 1211 of the second heat sink 121, and the first side edge of the first side wall 1111 is connected to the second side edge of the second side wall 1211. In this way, during the relative rotation of the first heat sink 111 and the second heat sink 121, the situation where the middle part of the first side wall 1111 and the middle part of the second side wall 1211 hinder the rotation of the second heat sink 121 and the first heat sink 111 can be reduced, thereby improving the working stability of the heat exchanger.

[0044] The first side portion and the second side portion can rotate relative to each other. When the heat exchanger is installed in the casing of the air-conditioning outdoor unit, the first side portion and the second side plate portion can be rotated relative to each other to adjust the inclination angle of the first heat dissipation plate 111 and / or the second heat dissipation plate 121 relative to the air-conditioning outdoor unit, thereby adjusting the lateral width of the entire heat exchanger, so that the heat exchanger can be adapted to air-conditioning outdoor units of different specifications and sizes, thereby improving the versatility of the heat exchanger.

[0045] Optionally, a first connecting hole is provided on the first side portion, and a second connecting hole is provided on the second side portion. A connecting pin is synchronously provided in the first connecting hole and the second connecting hole, and the connecting pin can rotate relative to the first connecting hole and the second connecting hole, so that the first heat dissipation plate 111 can rotate relative to the second heat dissipation plate 121.

[0046] Optionally, the heat exchange assembly 100 further includes a connecting plate, which is connected to the lower end of the heat dissipation plate 101 and is used to be fixedly connected to the bottom wall of the air conditioner outdoor unit.

[0047] For example, when the heat exchange assembly 100 is not fixedly connected to the air conditioner outdoor unit, the angle of the folding angle between two adjacent heat exchange assemblies 100 is adjustable, so that when the heat exchanger is installed in the air conditioner outdoor unit, the heat exchanger can be adapted to air conditioner outdoor units of different specifications. When the heat exchange assembly 100 is fixedly connected to the air conditioner outdoor unit, the angle of the folding angle between two adjacent heat exchange assemblies 100 is fixed, so as to reduce the movement of the heat exchange assembly 100 during the transportation or operation of the air conditioner outdoor unit, and improve the stability and reliability of the operation of the air conditioner outdoor unit.

[0048] Furthermore, if Figures 1 to 3 As shown, the plurality of heat exchange assemblies 100 further include a third heat exchange assembly 130, and the third heat exchange assembly 130 includes a third heat sink 131. Along the lateral direction of the air conditioner outdoor unit, the first heat exchange assembly 110, the second heat exchange assembly 120 and the third heat exchange assembly 130 are sequentially connected.

[0049] The third side wall 1212 of the second heat dissipation plate 121 is arranged opposite to the fourth side wall 1311 of the third heat dissipation plate 131, the third side wall 1212 is arranged opposite to the second side wall 1211, the third side edge portion of the third side wall 1212 is connected to the fourth side edge portion of the fourth side wall 1311, and the third side edge portion and the fourth side edge portion can rotate relative to each other.

[0050] In this embodiment, the first heat exchange assembly 110, the second heat exchange assembly 120 and the third heat exchange assembly 130 are sequentially connected along the horizontal direction of the air conditioner outdoor unit, the third side wall 1212 of the second heat sink 121 is arranged opposite to the fourth side wall 1311 of the third heat sink 131, and the third side edge of the third side wall 1212 is connected to the fourth side edge of the fourth side wall 1311. In this way, during the relative rotation of the second heat sink 121 and the third heat sink 131, the situation that the middle part of the third side wall 1212 and the middle part of the fourth side wall 1311 hinder the rotation of the third heat sink 131 and the second heat sink 121 can be reduced, thereby improving the working stability of the heat exchanger.

[0051] The second side wall 1211 is opposite to the third side wall 1212, the first side wall 1111 is opposite to the second side wall 1211, and the third side wall 1212 and the fourth side wall 1311 are opposite to each other, that is, the first heat exchange component 110 and the third heat exchange component 130 are respectively arranged on two opposite sides of the second heat exchange component 120.

[0052] The first side portion and the second side portion can rotate relative to each other, and the third side portion and the fourth side portion can rotate relative to each other. When the heat exchanger is installed in the casing of the air-conditioning outdoor unit, the first side portion and the second side portion can be rotated relative to each other, and / or the third side portion and the fourth side portion can be rotated relative to each other to adjust the inclination angle of the first heat dissipation plate 111 and / or the second heat dissipation plate 121 and / or the third heat dissipation plate 131 relative to the air-conditioning outdoor unit, thereby adjusting the lateral width of the entire heat exchanger, so that the heat exchanger can be adapted to air-conditioning outdoor units of different specifications and sizes, thereby improving the versatility of the heat exchanger.

[0053] Furthermore, if Figure 3 As shown, there is a first fold angle between the first heat dissipation plate 111 and the second heat dissipation plate 121, a second fold angle between the second heat dissipation plate 121 and the third heat dissipation plate 131, and the second side edge portion and the third side edge portion are diagonally arranged so that the opening direction of the first fold angle is opposite to the opening direction of the second fold angle.

[0054] In this embodiment, the second side edge of the second heat sink 121 is arranged diagonally with the third side edge, and the first angle between the first heat sink 111 and the second heat sink 121 and the second angle between the second heat sink 121 and the third heat sink 131 have opposite opening directions. In this way, the inclination direction of the first heat sink 111 can be the same as the inclination direction of the third heat sink 131. When multiple heat sinks 101 are arranged obliquely, compared with the angle opening directions between multiple heat sinks facing the same direction, this embodiment can reduce the overall extension width of the heat exchanger, reduce the space occupied by the heat exchanger in the air conditioner outdoor unit, and improve the compactness of the structural layout in the air conditioner outdoor unit.

[0055] In some optional embodiments, such as Figure 4 As shown, the heat exchanger further includes a liquid inlet pipe 400 and a liquid outlet pipe 500, and the liquid inlets of the plurality of heat exchange components 100 are respectively connected to the liquid inlet pipe 400. The liquid outlets of the plurality of heat exchange components 100 are respectively connected to the liquid outlet pipe 500.

[0056] For example, when the plurality of heat exchange assemblies 100 include a first heat exchange assembly 110 and a second heat exchange assembly 120 connected in sequence, the liquid inlet of the second heat exchange assembly 120 can also be connected to the liquid outlet of the first heat exchange assembly 110 .

[0057] In this embodiment, the liquid inlets of the plurality of heat exchange components 100 are respectively connected to the liquid inlet pipe 400, and the liquid outlets of the plurality of heat exchange components 100 are respectively connected to the liquid outlet pipe 500. In this way, the refrigerant in the liquid inlet pipe 400 can flow into the heat exchange tube 102 of the heat exchange component 100 through the liquid inlet of the heat exchange component 100, and the refrigerant in the heat exchange tube 102 can flow into the liquid outlet pipe 500 through the liquid outlet of the heat exchange component 100. Optionally, the liquid outlet of the heat exchange component 100 includes the liquid outlet of the heat exchange tube 102, and the liquid inlet of the heat exchange component 100 includes the liquid inlet of the heat exchange tube 102.

[0058] Taking a plurality of heat exchange components 100 including a first heat exchange component 110 and a second heat exchange component 120 connected in sequence as an example, the liquid outlet of the first heat exchange component 110 can also be connected to the liquid inlet of the second heat exchange component 120, and the refrigerant flowing out of the first heat exchange tube 112 of the first heat exchange component 110 can also flow into the second heat exchange tube 122 of the second heat exchange component 120.

[0059] When the liquid outlet of the first heat exchange component 110 and the liquid outlet of the second heat exchange component 120 are respectively connected to the liquid outlet pipe 500, the liquid outlet of the first heat exchange component 110 is not connected to the liquid inlet of the second heat exchange component 120, and the liquid inlets of the first heat exchange component 110 and the second heat exchange component 120 are respectively connected to the liquid inlet pipe 400, the first heat exchange tube 112 of the first heat exchange component 110 and the second heat exchange tube 122 of the second heat exchange component 120 are arranged in parallel.

[0060] When the liquid outlet of the first heat exchange assembly 110 is connected to the liquid inlet of the second heat exchange assembly 120, and the liquid inlet of the second heat exchange assembly 120 is not connected to the liquid inlet pipe 400, the first heat exchange tube 112 and the second heat exchange tube 122 are arranged in series. In this way, the first heat exchange tube 112 and the second heat exchange tube 122 can be switched between parallel arrangement and series arrangement to change the flow length of the refrigerant in the heat exchange tube 102, thereby changing the heat exchange capacity of the heat exchanger, so that the heat exchanger can be adapted to air conditioner outdoor units of different specifications, or the heat exchange capacity of the air conditioner outdoor unit can be changed, thereby improving the versatility of the heat exchanger.

[0061] It should be noted that, in the present embodiment, the first heat exchange component 110 and the second heat exchange component 120 refer to the preceding heat exchange component 100 and the succeeding heat exchange component 100 of two adjacent heat exchange components 100. When the number of heat exchange components 100 is greater than two, the same heat exchange component 100 is the second heat exchange component 120 for the preceding heat exchange component 100 and is the first heat exchange component 110 for the succeeding heat exchange component 100.

[0062] Furthermore, if Figure 4As shown, the heat exchanger further includes a liquid outlet three-way valve 200 and a liquid inlet three-way valve 300. The first end of the liquid outlet three-way valve 200 is connected to the liquid outlet of the first heat exchange component 110, and the second end of the liquid outlet three-way valve 200 is connected to the liquid outlet pipeline. The first end of the liquid inlet three-way valve 300 is connected to the liquid inlet pipeline 400, the second end of the liquid inlet three-way valve 300 is connected to the third end of the liquid outlet three-way valve 200, and the third end of the liquid inlet three-way valve 300 is connected to the liquid inlet of the second heat exchange component 120.

[0063] Among them, the second end of the liquid outlet three-way valve 200 and the third end of the liquid outlet three-way valve 200 can be selectively connected to the first end of the liquid outlet three-way valve 200, and the first end of the liquid inlet three-way valve 300 and the second end of the liquid inlet three-way valve 300 can be selectively connected to the third end of the liquid inlet three-way valve 300.

[0064] In this embodiment, the second end of the liquid outlet three-way valve 200 and the third end of the liquid outlet three-way valve 200 can be selectively connected to the first end of the liquid outlet three-way valve 200, and the first end of the liquid inlet three-way valve 300 and the second end of the liquid inlet three-way valve 300 can be selectively connected to the third end of the liquid inlet three-way valve 300. When the first heat exchange tube 112 and the second heat exchange tube 122 are arranged in parallel, the first end of the liquid outlet three-way valve 200 and the second end of the liquid outlet three-way valve 200 can be connected, and the first end of the liquid inlet three-way valve 300 and the third end of the liquid inlet three-way valve 300 are connected. When the first heat exchange tube 112 and the second heat exchange tube 122 are arranged in series, the first end of the liquid outlet three-way valve 200 and the third end of the liquid outlet three-way valve 200 can be connected, and the second end of the liquid inlet three-way valve 300 can be connected to the third end of the liquid inlet three-way valve 300.

[0065] In this way, the first heat exchange tube 112 and the second heat exchange tube 122 can be switched between a parallel setting and a series setting through the liquid inlet three-way valve 300 and the liquid outlet three-way valve 200 to change the flow length of the refrigerant in the heat exchange tube 102, thereby changing the heat exchange capacity of the heat exchanger, so that the heat exchanger can be adapted to air-conditioning outdoor units of different specifications, or the heat exchange capacity of the air-conditioning outdoor unit can be changed, thereby improving the versatility of the heat exchanger.

[0066] In some optional embodiments, such as Figures 1 to 3 As shown, among the heat dissipation plates 101 of the plurality of heat exchange assemblies 100 , at least two heat dissipation plates 101 have different lateral widths.

[0067] In this embodiment, among the heat sinks 101 of the plurality of heat exchange assemblies 100, at least two heat sinks 101 have different transverse widths, and when the heat sinks 101 have the same inclination angle, the transverse lengths of the heat sinks 101 along the air conditioner outdoor unit may also be different. This can increase the flexibility of adjusting the position of the heat sink 101, thereby increasing the flexibility of setting the length of the heat exchanger and improving the versatility of the heat exchanger.

[0068] Furthermore, among the heat exchange tubes 102 of the multiple heat exchange assemblies 100, at least two heat exchange tubes 102 have different lengths. The transverse widths of the heat exchange plates 101 are different, and the number of sub-tube segments that can be set in the heat exchange tubes 102 is also different, that is, the lengths of the heat exchange tubes 102 in one heat exchange assembly 100 can also be different. In this way, the heat dissipation efficiency of the heat exchange plates 101 is different. By adjusting the parallel and series settings of different heat exchange tubes 102, the heat exchanger can have a variety of different heat exchange efficiencies, thereby improving the versatility and adaptability of the heat exchanger.

[0069] Exemplarily, in the case where the multiple heat exchange assemblies 100 include a first heat exchange assembly 110, a second heat exchange assembly 120 and a third heat exchange assembly 130 connected in sequence, the lateral width of the first heat exchange plate 111 of the first heat exchange assembly 110 is greater than or equal to the lateral width of the second heat exchange plate 121 of the second heat exchange assembly 120, and the lateral width of the second heat exchange plate 121 is greater than or equal to the lateral width of the third heat exchange plate 131 of the third heat exchange assembly 130.

[0070] In this embodiment, the lateral width of the heat sink 101 of the multiple heat exchange components 100 can be gradually reduced, and the heat sink 101 with reduced lateral width occupies a smaller width of the air-conditioning outdoor unit when it is set at an angle, so as to increase the flexibility of adjusting the position of the heat sink 101, improve the flexibility of setting the length of the heat exchanger, and improve the versatility of the heat exchanger.
