[0027] Referring to Fig. 1, the embodiment discloses a heat exchanger, which comprises a flat tube 1, a fin 2, a header 3, a connecting pipe 4 and a side plate 5. Figures 1 to 6

[0028] ​​For the convenience of the description of the embodiment of the utility model, through the first direction, the second direction and the third direction to assist the explanation, the first direction, the second direction and the third direction are perpendicular two by two, wherein D1 in the drawing indicates the first direction, D2 indicates the second direction, and D3 indicates the third direction.

[0029] The flat tubes 1 are arranged along the first direction, the fins 2 are fixedly arranged on the outer surfaces of the flat tubes 1, two collecting tubes 3 are arranged on the two sides of the flat tubes 1 along the second direction, a connecting pipe 4 is connected to the two collecting tubes 3, and two side plates 5 are arranged on the two sides of the flat tubes 1 along the first direction.

[0030] The two collecting tubes 3 are respectively provided with a plurality of insertion holes 33 on the sides close to each other, which are matched with the end portions of the flat tubes 1, the two ends of the flat tubes 1 along the second direction are respectively inserted into the insertion holes 33 of the two collecting tubes 3, so as to connect the flat tubes 1 and the collecting tubes 3, and the connection between the flat tubes 1 and the collecting tubes 3 is sealed, so as to prevent internal medium from leaking.

[0031] The two collecting tubes 3 are respectively provided with an insertion hole 32 on the sides close to each other, which is matched with the end portion of the connecting pipe 4, the two ends of the connecting pipe 4 along the second direction are respectively inserted into the insertion holes 32 of the two collecting tubes 3, so as to connect the connecting pipe 4 and the collecting tubes 3, and the connection between the connecting pipe 4 and the collecting tubes 3 is also sealed, so as to prevent internal medium from leaking.

[0032] The two side plates 5 are respectively abutted to the two flat tubes 1 on the two sides along the first direction, the two ends of the side plates 5 along the second direction are respectively abutted to the two collecting tubes 3, and the connecting pipe 4 is at least partially located in the side plates 5. Further, the side plates 5 are provided with arc-shaped portions 501 which are matched with the collecting tubes 3 and abutted thereto. In this way, the side plates 5 are connected to the collecting tubes 3 and the flat tubes 1, the structural stability and integrity are improved, and the connecting pipe 4 is wrapped in the side plates 5, so that heat loss can be reduced.

[0033] Further, the abutted portions of the side plates 5 and the collecting tubes 3 are welded and fixed, and the abutted portions of the side plates 5 and the flat tubes 1 are also welded and fixed, so as to strengthen the fixation between the side plates 5, the collecting tubes 3 and the flat tubes 1, and improve the strength and integrity of the heat exchanger.

[0034] The side plates 5 of the embodiment include a first plate 51 and a second plate 52, the two second plates 52 are arranged in parallel along the third direction, the two second plates 52 are perpendicularly extended from the two sides of the first plate 51 along the third direction and towards the side close to the flat tubes 1, and the arc-shaped portions 501 are arranged on the two sides of the first plate 51 along the second direction, so as to be matched with and abutted to the outer peripheral walls of the collecting tubes 3. The two sides of the first plate 51 along the second direction and the two sides of the second plate 52 along the second direction are all abutted to the collecting tubes 3. In this way, the installation precision of the heat exchanger is improved, and the sealing performance of the connection between the side plates 5 and the collecting tubes 3 is also improved.

[0035] Further, the second plate 52 abuts the flat tube 1 on the outer side, i.e. on both sides of the first direction, away from the first plate 51. In this way, when the heat exchanger is assembled, the side plate 5 can be accurately positioned by the manifold 3 and the flat tube 1, facilitating the bundling and fixing of the entire heat exchanger product.

[0036] The connecting pipe 4 is located between the first plate 51 and the flat tube 1 in the first direction, between the two second plates 52 in the third direction, and between the two manifolds 3 in the second direction. The flat tube 1, the side plate 5, and the two manifolds 3 together enclose a space, and the connecting pipe 4 is located in the space. In this way, the side plate 5 can shield the gap between the connecting pipe 4 and the flat tube 1, preventing air from leaking out of the gap and reducing the heat exchange efficiency.

[0037] In some embodiments, the side plate 5 further comprises a third plate 53, and the two third plates 53 extend from the side of the two second plates 52 away from the first plate 51, respectively. There is a gap between the two third plates 53, and the third plate 53 abuts the flat tube 1. In this way, the contact area between the side plate 5 and the flat tube 1 is increased, thereby improving the structural stability.

[0038] Further, the abutting part of the third plate 53 and the flat tube 1 is welded and fixed.

[0039] The manifold 3 is also provided with a pipe opening 31 for connecting the heat exchanger with other devices. In this embodiment, one of the manifolds 3 is provided with three pipe openings 31, and the other manifold 3 is not provided.

[0040] Since the strength of the pipe opening 31 of the manifold 3 is higher, the side plate 5 at least partially abuts the pipe opening 31. Specifically, the side plate 5 and the pipe opening 31 are located at the same height position in the first direction, one of the second plates 52 of the side plate 5 abuts the pipe opening 31, and the other second plate 52 abuts the outer wall of the manifold 3. Since the pipe opening 31 is thickened, the length of the second plate 52 abutting the pipe opening 31 in the second direction is less than the length of the second plate 52 abutting the outer wall of the manifold 3 in the second direction. In this way, the structural stability and strength of the heat exchanger are further improved.

[0041] In some embodiments, the heat exchanger further comprises a partition plate 6, which can be inserted and fixed in the manifold 3 to block the internal passage of the manifold 3 and limit the flow of the internal medium.

[0042] The side plate 5 is provided with a mounting hole 54 for fixing the entire heat exchanger product. Specifically, the mounting hole 54 is provided on the side plate 5 located on the upper side, and is provided on the first plate 51 of the side plate 5.

[0043] In summary, compared with the prior art, the heat exchanger has the following advantages: a heat exchanger with a novel structure is provided, arc-shaped portions are arranged at both ends of the side plate, the side plate is adapted to abut against the header through the arc-shaped portions in the transverse direction (i.e., the second direction), and the side plate abuts against the flat tube in the longitudinal direction (i.e., the first direction), and the connecting pipe is arranged in the side plate, compared with the prior art in which the side plate and the fin are welded together, the heat exchanger has higher structural stability and integrity, is simple to assemble, has high installation precision, can reduce the gap between the flat tube and the connecting pipe, reduces the heat loss taken away by the wind, and thus improves the heat exchange efficiency.
