[0003] In related technologies, bendable heat exchangers are often formed using a press brake. However, as the heat exchanger's dimensions change, the bending difficulty of the press brake also varies. For example, to ensure performance, the heat exchanger is often taller. This height easily causes the heat exchanger's dimensions to exceed the processing range of conventional press brakes, making the bending process more difficult and increasing the processing cost.

[0007] In one embodiment, there are multiple connecting members, and the multiple connecting members are arranged at intervals along the extension direction of the heat exchange unit.
[0008] In one embodiment, the heat exchanger further includes foam, which is installed between two adjacent heat exchange units, and the two opposite side surfaces of the foam are respectively fitted with the two adjacent heat exchange units; wherein one side surface of the main body is fitted with the foam.
[0009] In one embodiment, at least one side surface of the foam is bonded to the corresponding heat exchange unit.
[0010] In one embodiment, the thicknesses of two adjacent heat exchange units are the same or different.

[0027] Bent heat exchangers are currently commonly used in air-conditioning systems to exchange heat with the outside world due to their compact structure, easy installation, and more efficient heat exchange efficiency.
[0028] In related technologies, bendable heat exchangers are often formed using a press brake. However, as the heat exchanger's dimensions change, the bending difficulty of the press brake also varies. For example, to ensure performance, the heat exchanger is often taller. This height easily causes the heat exchanger's dimensions to exceed the processing range of conventional press brakes, making the bending process more difficult and increasing the processing cost.
[0029] See also Figure 1-Figure 3 In order to solve the problem that existing heat exchangers are difficult to process using a bending machine when they are relatively tall, the present application provides a heat exchanger 100, which includes a connector 10 and a plurality of heat exchange units 20. The plurality of heat exchange units 20 are arranged side by side along the height direction of the heat exchanger 100, and at least a portion of the planar projection of the heat exchange units 20 along the height direction of the heat exchanger 100 is in the shape of an arc. In other words, the heat exchange units 20 are a structure that is bent around a straight line parallel to the height direction of the heat exchange units 20. It should be noted that the height direction of the heat exchanger 100 is the arrangement direction of the plurality of heat exchange units 20, the extension direction of the heat exchanger 100 is the extension direction of the internal heat exchange tube 22, and the thickness direction of the heat exchanger 100 is perpendicular to the height direction and the extension direction of the heat exchanger 100.
[0030] Furthermore, the connecting member 10 is arranged between two adjacent heat exchange units 20, and a first U-shaped groove 101 and a second U-shaped groove 102 are provided on the connecting member 10. The groove openings of the first U-shaped groove 101 and the second U-shaped groove 102 are oriented in opposite directions, and the first U-shaped groove 101 is sleeved and clamped on the outer side surface of one of the heat exchange units 20, and the second U-shaped groove 102 is sleeved and clamped on the outer side surface of the other adjacent heat exchange unit 20.
[0031] It is understandable that by dividing the heat exchanger 100 into multiple heat exchange units 20, the present application can reduce the height of each heat exchange unit 20 accordingly, thereby reducing the difficulty of bending each heat exchange unit 20. In this way, when multiple heat exchange units 20 are arranged and combined to form the heat exchanger 100, the overall height of the heat exchanger 100 can be increased, thereby improving the heat exchange effect, and the overall processing difficulty and cost of the heat exchanger 100 can be reduced. In addition, adjacent heat exchange units 20 are connected by limited locking through the connector 10, which can effectively fix the heat exchange units 20, thereby greatly improving the structural stability of the heat exchanger 100 and facilitating the processing and transportation of the heat exchanger 100.
[0032] Specifically, if Figure 1 As shown, the heat exchange unit 20 in this embodiment is U-shaped. In other embodiments, the heat exchange unit 20 can also be bent into an L-shape, a G-shape, or a circular shape. In other words, the structure of the split heat exchange unit 20 and the connector 10 in this application can be applied to various different types of heat exchangers 100.
[0033] Typically, the heat exchange unit 20 includes fins 21 and heat exchange tubes 22. The fins 21 are arranged along the extension direction of the heat exchange tubes 22 and connected to the heat exchange tubes 22. Here, the extension direction of the heat exchange tubes 22 corresponds to the extension direction of the heat exchange unit 20, and the width direction of the fins 21 corresponds to the thickness direction of the heat exchange unit 20. The fins 21 can be connected to multiple rows of heat exchange tubes 22 along the thickness direction of the heat exchange unit 20.
[0034] For example, Figure 1 and Figure 2 As shown, this embodiment specifically includes two heat exchange units 20, defined herein as a first unit 20a and a second unit 20b. The fins 21 of the first unit 20a are provided with three rows of heat exchange tubes 22, while the fins 21 of the second unit 20b are provided with two rows of heat exchange tubes 22. In other embodiments, the heat exchange units 20 may also be provided with four, five, or even more rows of heat exchange tubes 22. To facilitate transportation and reduce the risk of damage from collisions, the outer sides of the multiple heat exchange units 20 are preferably flush.
[0035] In one embodiment, if Figure 2As shown, the thickness of two adjacent heat exchange units 20 can be the same or different. It is understood that each heat exchange unit 20 can achieve different heat exchange effects by varying the width of the internal fins 21 and the number of rows of corresponding heat exchange tubes 22. Furthermore, the dimensions of the first U-shaped groove 101 and the second U-shaped groove 102 on the connector 10 can be flexibly adjusted based on the thickness of the corresponding heat exchange unit 20, enabling a fixed connection between heat exchange units 20 of the same or different thicknesses, making the configuration of the heat exchanger 100 more flexible.
[0036] Furthermore, in one embodiment, Figure 1 As shown, the heat exchanger 100 further includes sleeve plates 40, which are disposed at opposite ends of the heat exchange unit 20 in the extension direction and are connected to the plurality of heat exchange units 20. The sleeve plates 40 are used to integrally fix the plurality of heat exchange units 20, thereby further improving the reliability of the overall connection of the heat exchanger 100.
[0037] In one embodiment, if Figure 3 As shown, the connector 10 includes a main body 11, a first fixing portion 12, and a second fixing portion 13. The two opposite side surfaces of the main body 11 are respectively in contact with the side surfaces of two adjacent heat exchange units 20. One end of the first fixing portion 12 is connected to one side surface of the main body 11, and the other end extends away from the main body 11. One end of the second fixing portion 13 is connected to the other side surface of the main body 11, and the other end extends away from the first fixing portion 12. The first fixing portion 12 forms a first U-shaped groove 101, and the second fixing portion 13 forms a second U-shaped groove 102. In this way, the connector 10 has a simple structure and is easy to process. The first fixing portion 12 and the second fixing portion 13 can reasonably set the size of the U-shaped groove according to the size of the heat exchange unit 20, thereby achieving a clamping effect on the heat exchange unit 20 and improving the stability of the overall connection.
[0038] Taking the first U-shaped groove 101 and the first unit 20a, and the second U-shaped groove 102 and the second unit 20b as an example, in order to further improve the reliability of the connection, in one embodiment, the number of the first fixing part 12 and / or the second fixing part 13 can be set to one or more.
[0039] For example, Figure 2 and Figure 3 As shown, in this embodiment, one first fixing portion 12 and two second fixing portions 13 are specifically provided. Of course, other numbers of first fixing portions 12 and second fixing portions 13 may also be used. The lengths of the first fixing portion 12 and the second fixing portion 13 may also be selected as appropriate according to the actual clamping effect, and are not limited here.
[0040] Furthermore, in one embodiment, there are multiple connectors 10, and the multiple connectors 10 are arranged at intervals along the extension direction of the heat exchange unit 20. In this way, the connection reliability of adjacent heat exchange units 20 is further improved.
[0041] In one embodiment, if Figure 1 As shown, the heat exchanger 100 is defined as having two opposite ends along its height direction, namely a first end and a second end. The heat exchanger 100 further includes a clamping member 50, which can be inserted into the outer side surface of the first end, or the outer side surface of the second end. Of course, the clamping member 50 can also be inserted into the outer side surfaces of both the first and second ends to clamp the corresponding heat exchange unit 20.
[0042] Since each heat exchange unit 20 is composed of multiple rows of fins 21, and connectors 10 are provided between adjacent heat exchange units 20, the connectors 10 can simultaneously clamp the fins 21 while connecting the adjacent heat exchange units 20. However, the multiple rows of fins 21 at the first and second ends are not secured by connectors 10 and have poor stability. Therefore, the present application further improves the installation stability between the fins 21 at both ends of the height of the heat exchanger 100 by providing clamping members 50 at the first and second ends.
[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the heat exchanger 100 also includes foam 30, which is installed between two adjacent heat exchange units 20, with the opposite sides of the foam 30 respectively attached to the two adjacent heat exchange units 20. One side of the main body 11 is attached to the foam 30. The foam 30 has a certain degree of elasticity, which can act as a buffer, reducing the probability of damage due to vibration and collision during transportation, making the transportation process more convenient.
[0044] Furthermore, in one embodiment, at least one side surface of the foam 30 is bonded to the corresponding heat exchange unit 20. In this way, the connection between the foam 30 and the heat exchange unit 20 is more secure.
[0045] The present application also provides an air-conditioning system, which includes the heat exchanger 100 described in any one of the above embodiments.
[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
