[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention will be described in detail below.

[0042] See also Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the heat exchanger provided in an embodiment of the present application along the first direction, Figure 2 This is a schematic diagram of the structure of the heat exchanger provided in an embodiment of the present application along the second direction, Figure 3 for Figure 1 The schematic diagram of the structure of the first sheet metal plate in the heat exchanger shown in FIG. Figure 4 for Figure 1Schematic diagram of the structure of the second sheet metal plate in the heat exchanger shown. The embodiment of the present application provides a heat exchanger 100, which is applied to an air conditioner. The heat exchanger 100 includes an air pipe module 10, a heat exchange module 20, a connecting pipe module 30 and a liquid pipe module 40 connected in sequence. The air pipe module 10 includes a first air pipe unit 110 and a second air pipe unit 120 arranged opposite to each other. The heat exchange module 20 includes a first heat exchange unit 210 and a second heat exchange unit 220 arranged opposite to each other. The connecting pipe module 30 includes a first connecting pipe unit 310 and a second connecting pipe unit 320 arranged opposite to each other. The liquid pipe module 40 includes a first liquid pipe unit 410 and a second liquid pipe unit 420 arranged opposite to each other. The first air pipe unit 110, the first connecting pipe unit 310, the first heat exchange unit 210 and the first liquid pipe unit 410 are arranged on the first sheet metal plate 50 in sequence. The second air pipe unit 120, the second connecting pipe unit 320, the second heat exchange unit 220 and the second liquid pipe unit 420 are arranged on the second sheet metal plate 60 in sequence. The first sheet metal plate 50 and the second sheet metal plate 60 are connected opposite to each other. The present application directly sets the first air pipe unit 110, the first connecting pipe unit 310, the first heat exchange unit 210 and the first liquid pipe unit 410 on the first sheet metal plate 50, sets the second air pipe unit 120, the second connecting pipe unit 320, the second heat exchange unit 220 and the second liquid pipe unit 420 on the second sheet metal plate 60, and connects the first sheet metal plate 50 and the second sheet metal plate 60 to form an air pipe module 10, a liquid pipe module 40, a heat exchange module 20 and a connecting pipe module 30. The heat exchanger 100 greatly reduces the number of parts, thereby reducing the installation process and saving time. In addition, by making modular settings on the sheet metal plate, some modules can be replaced separately, reducing the cost of repeated mold opening.

[0043] The connecting pipe module 30 includes a plurality of adjustable flow tubes, one end of each adjustable flow tube is connected to the heat exchange module 20 , and the other end is connected to the liquid pipe module 40 , so as to allow the refrigerant in the liquid pipe module 40 to flow into the heat exchange module 20 .

[0044] It is understandable that the capacity of each adjustable flow tube can be set according to actual conditions, so that the heat exchanger 100 can control the refrigerant flow entering the heat exchange module 20 by replacing the adjustable flow tubes of different capacity sizes. In addition, after selecting the corresponding adjustable flow tube, the flow parameters are fixed and die-casting is performed to form the adjustable flow tube, which can effectively reduce the development time of the refrigerant distribution of the internal unit regulating flow path.

[0045] In some embodiments, the first air pipe unit 110, the first heat exchange unit 210 and the first liquid pipe unit 410 are integrally formed. The integral forming setting can be performed by sheet metal die-casting, which reduces production complexity and greatly improves assembly efficiency.

[0046] In some embodiments, the second air pipe unit 120, the second heat exchange unit 220 and the second liquid pipe unit 420 are integrally formed. The integral forming setting can be performed by sheet metal die-casting, which reduces production complexity and greatly improves assembly efficiency.

[0047] At least one first positioning hole 510 is provided on the first sheet metal plate 50, and at least one second positioning hole 620 is provided on the second sheet metal plate 60. One first positioning hole 510 is provided corresponding to one second positioning hole 620, and the first sheet metal plate 50 and the second sheet metal plate 60 are positioned by the first positioning hole 510 and the second positioning hole 620. Through the provision of the first positioning hole 510 and the second positioning hole 620, precise positioning can be completed, thereby achieving precise welding between the first sheet metal plate 50 and the second sheet metal plate 60. Exemplarily, the external welding tool can insert a cylindrical positioning rod into the first positioning hole 510 and the second positioning hole 620, so as to facilitate mutual welding of the first sheet metal plate 50 and the second sheet metal plate 60 and improve assembly efficiency.

[0052] It can be understood that the number of the third positioning interfaces 250 is consistent with the number of the first positioning interfaces 240, that is, one third positioning interface 250 is set in a one-to-one correspondence with one first positioning interface 240, so that the refrigerant in the liquid pipe module 40 flows to the heat exchange through the first positioning interface 240, and the formed gas flows to the air pipe module 10 through the third positioning interface 250 of the heat exchange.

[0053] The relative position between the third positioning interface 250 and the first positioning interface 240 can be set according to actual needs and is not specifically limited here.

A plurality of second positioning interfaces 430 are provided on the side of the liquid pipe module 40 close to the heat exchange, and the first positioning interface 240 and the second positioning interface 430 are used to connect the connecting pipe module 30, that is, one end of the adjustable flow pipe is connected to the first positioning interface 240, and the other end is connected to the second positioning interface 430.
