[0008] In some embodiments, the notch extends along the thickness direction of the main body;

[0009] And / or, along the thickness direction of the main body, the length of the notch is less than or equal to the length of the connecting plate.

[0010] In some embodiments, the notch extends along the thickness direction of the main body, and along the thickness direction of the main body, the notch penetrates through one end face of the connecting plate away from the main body and communicates with one side.

[0011] In some embodiments, the number of the straight portions is two. Along the width direction of the main body, the two straight portions are disposed on both sides of the arc portion, and the distance between the connection positions of the two straight portions and the arc portion is less than the width of the connecting plate.

[0012] In some embodiments, along the thickness direction of the main body, the length of the connecting plate is X1;

[0013] Wherein, 5mm ≤ X1 ≤ 8mm.

[0014] In some of these embodiments, a blocking portion is provided at one end of the main body close to the connecting plate.

[0015] In some of these embodiments, the blocking portion extends along the width direction of the main body;

[0016] and / or, the blocking portion and the main body are of an integrally formed structure.

[0017] In some of these embodiments, the length of the straight portion along the width direction of the main body is T, the thickness of the main body of the side plate is t, and the relational expression is satisfied: T > t.

[0018] According to a second aspect of the present invention, there is also provided a heat exchanger, including a header pipe, flat tubes, fins, and the side plate as described above.

[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present utility model will be thorough and complete and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0042] This embodiment provides a heat exchanger, as Figures 1 - 2 shown. The heat exchanger includes a header 200, flat tubes 300, and side plates 100. The side plates 100 and the flat tubes 300 are arranged in parallel at intervals and are perpendicular to the header 200. The header 200 is arranged at the end of the side plates 100 along the length direction of the side plates 100 and is communicated with the flat tubes 300. The header 200 is used to accommodate a medium. Among them, the medium includes, but is not limited to, media with heat exchange functions such as water and coolant.

[0043] Exemplarily, the number of the headers 200 is two, and the two headers 200 are respectively arranged at both ends of the side plate 100 along the length direction of the side plate 100. The number of the side plates 100 is two, and the number of the flat tubes 300 is multiple. The two side plates 100 are arranged at both ends of the header 200 along the axial direction of the header 200, and the multiple flat tubes 300 are arranged in parallel at intervals between the two side plates 100, that is, the two side plates 100 are located outside the multiple flat tubes 300, playing a role in protecting the flat tubes 300. At this time, both ends of the multiple flat tubes 300 along the length direction of the side plate 100 are respectively communicated with the two headers 200, forming a plurality of microchannel structures and improving the heat exchange efficiency.

[0044] In one embodiment, the heat exchanger further includes fins (not shown in the figure), and at least part of the fins are arranged between the side plate 100 and the flat tube 300 adjacent to the side plate 100. The fins can increase the contact area and improve the heat exchange effect.

[0045] Exemplarily, the fin can be a single-piece structure, and the cross-section of the fin can also be a wavy structure to increase the contact area.

[0046] Of course, it can be understood that the fins can also be arranged between two adjacent flat tubes 300, so that the multiple flat tubes 300 and the multiple fins are arranged in a staggered manner, that is, heat dissipation can be carried out through the fins on both sides of the flat tube 300, further improving the heat exchange effect.

[0047] This embodiment also provides a side plate 100, as Figures 2 - 3 shown, the side plate 100 includes a main body 1. The main body 1 is a plate-like structure, and the outer shape of the main body 1 is similar to a cuboid structure. The main body 1 and the flat tube 300 are arranged in parallel at intervals, and the two headers 200 are respectively arranged at both ends of the main body 1 along the length direction of the main body 1.

[0048] Wherein, the length direction of the main body 1 is defined as L, the width direction of the main body 1 is defined as B, and the thickness direction of the main body 1 is defined as D. The length direction, width direction and thickness direction of the main body 1 are perpendicular to each other pairwise. The length direction, width direction and thickness direction of the main body 1 only represent the spatial directions and have no substantial meaning.

[0049] If the side plate 100 and the header 200 are directly fixed, since the contact area between the side plate 100 and the header 200 is relatively small, there will be a situation where the side plate 100 and the header 200 are disengaged.

[0050] For this reason, as Figures 2 - 5As shown in the figure, the side plate 100 provided in this embodiment further includes a connecting plate 2. The connecting plate 2 is arranged at at least one end of the main body 1 along the length direction of the main body 1 and extends along the thickness direction of the main body 1. The connecting plate 2 includes an arc portion 21 and a straight portion 22. The straight portion 22 is arranged at at least one side of the arc portion 21 along the width direction of the main body 1. An installation groove 211 is provided in the arc portion 21, and the installation groove 211 is used for installing the manifold 200.

[0051] In the side plate 100 provided in this embodiment, the connecting plate 2 extends along the thickness direction of the main body 1. When installing the manifold 200, the contact area between the side plate 100 and the manifold 200 is increased, thereby improving the connection strength between the side plate 100 and the manifold 200. The arc portion 21 of the connecting plate 2 is adapted to the outer side wall of the manifold 200, reducing the occupied space and facilitating full contact and cooperation between the connecting plate 2 and the manifold 200. At the same time, the straight portion 22 is arranged at at least one side of the arc portion 21 along the width direction of the main body 1. The straight portion 22 actually serves to increase the thickness of the edge of the arc portion 21, avoiding the risk that the manifold 200 is likely to split open the installation groove 211 during installation, and improving the overall structural strength of the connecting plate 2.

[0052] Specifically, the manifold 200 and the installation groove 211 are connected by welding. The arc segment is fixed to the outer wall of the manifold 200 by welding, increasing the welding area and improving the connection strength between the side plate 100 and the manifold 200. Specifically, before the side plate 100 passes through the furnace, it can be welded by argon arc welding, or argon arc welding may not be required, and it can be welded in a brazing furnace.

[0053] Among them, the installation groove 211 is an arc-shaped structure, and the outer wall of the manifold 200 fits with the arc-shaped structure. That is, the inner wall contour shape of the installation groove 211 is adapted to the manifold 200, and at least part of the manifold 200 is accommodated in the installation groove 211, increasing the fixing effect between the installation groove 211 and the manifold 200. It can be understood that the installation groove 211 is a through groove structure along the thickness direction of the main body 1, and the manifold 200 can penetrate through the installation groove 211, so that one manifold 200 can be connected to two side plates 100 and multiple flat tubes 300 at the same time.

[0054] It can be understood that the structure of the flat tube 300 is similar to that of the side plate 100, and the flat tube 300 can also have an installation groove 211 with an arc-shaped structure, which is convenient for the installation and fixation between the side plate 100 and the manifold 200.

[0055] Among them, the number of the straight portions 22 is two. Along the width direction of the main body 1, the two straight portions 22 are arranged on both sides of the arc portion 21.

[0056] In this way, the arc portion 21 is arranged between the two straight portions 22, and the two straight portions 22 achieve double-sided protection of the arc portion 21, and at the same time, the balance effect of the connecting plate 2 can also be achieved.

[0057] Wherein, the distance between the connection positions of the two straight portions 22 and the arc portion 21 is less than the width of the connecting plate 2.

[0058] In other words, the distance between the two end points of the projection of the installation groove 211 on the reference plane along the width direction of the main body 1 is less than the width of the connecting plate 2, and the reference plane is the plane where the length direction and the width direction of the main body 1 are located.

[0059] Adopting this method can increase the structural strength of the connecting plate 2 along the width direction of the main body 1, thereby improving the stability of the overall structure of the heat exchanger.

[0060] During the brazing process in the brazing furnace, part of the composite material on the header 200 will flow onto the two outermost side plates 100 after melting, resulting in two fins being welded to the corresponding side plates 100. Therefore, when the fins are subsequently separated from the corresponding side plates 100, it is very difficult to clean the solder between the fins and the side plates 100.

[0061] To solve this problem, as Figures 2 - 5 shown, a blocking portion 11 is provided at one end of the main body 1 close to the connecting plate 2.

[0062] By processing and forming the blocking portion 11 on the side plate 100, the blocking portion 11 can block the flow of the composite material on the header 200 to the middle part of the side plate 100. During the brazing process in the brazing furnace, the blocking portion 11 is used to block the melted composite material on the header 200 from flowing to the position of the fins, reducing the risk of the melted composite material on the header 200 flowing to the fins. Furthermore, it reduces the risk of adhesion caused by the fins being welded to the side plates 100. At the same time, it can also reduce the risk of the fins bouncing open and contacting the header 200, resulting in the erosion of the fins.

[0063] Wherein, the blocking portion 11 extends along the width direction of the main body 1 to interrupt the flow path of the melted composite material from the end of the side plate 100 to the middle part of the side plate 100.

[0064] Wherein, the blocking portion 11 is integrally formed with the corresponding side plate 100, so as to facilitate the addition and formation of the blocking portion 11 on the side plate 100, reducing the processing and assembly links of parts and saving production costs.

[0065] Specifically, as Figures 4 - 5 shown, the blocking portion 11 is a groove, and the melted composite material can enter the groove. The groove serves to accommodate the composite material and actually functions as an overflow groove. At the same time, one side of the main body 1 along the thickness direction of the main body 1 is a groove, and the other side will form a complementary structure. The end of the fin abuts against the complementary structure on the corresponding side plate 100, increasing the fixing effect of the fin.

[0066] Specifically, asFigure 6 As shown, the blocking portion 11 is a rib, and it is difficult for the melted composite material to exceed the rib, achieving the isolation of the composite material and restricting the overflow range of the composite material between the manifold 200 and the rib.

[0067] Among them, as Figure 7 shown, the projection of the blocking portion 11 on the reference plane is at least one of a polygonal structure and an arc; wherein, the reference plane is the plane where the length direction and the width direction of the main body 1 are located. Exemplarily, the projection of the blocking portion 11 on the reference plane can be regular shapes such as a triangle, a quadrilateral, a pentagon, a star, a circle, an ellipse, a kidney shape, or other irregular shapes.

[0068] Specifically, the blocking portion 11 is a through hole (not shown in the figure), so that the melted composite material on the manifold 200 can be drained into the through hole, thereby achieving the blocking effect on the melted composite material on the manifold. Among them, the through hole is a round hole, an oval hole, a kidney hole, a square hole or a hole with other irregular shapes.

[0069] Specifically, as Figure 8 shown, the blocking portion 11 may also not be a continuous structure. For example, the blocking portion 11 includes a plurality of spaced-apart protrusions, and the plurality of protrusions are arranged along the width direction of the main body 1.

[0070] The plurality of protrusions are spaced apart, and the number of protrusions and the spacing between two adjacent protrusions can be freely adjusted. Exemplarily, the shape of the protrusion can be an arc, for example, a hemispherical structure, and the blocking portion 11 can be called a positioning bubble. Of course, other square protrusions, pentagram protrusions and other structures are also within the protection scope of this patent.

[0071] It can be understood that there are a plurality of blocking portions 11 in this embodiment, some of the blocking portions 11 are ribs, and some of the blocking portions 11 are through holes. Of course, it should be noted that the blocking portion 11 can be set in any combination form of ribs, grooves and through holes according to the usage requirements, and its specific form can be adjusted according to the actual production situation.

[0072] Exemplarily, along the thickness direction of the main body 1, the length of the connecting plate 2 is X1; wherein, 5mm ≤ X1 ≤ 8mm. By adopting this method, the contact area between the arc portion 21 and the manifold 200 can be guaranteed, the improvement effect can be increased, and the length of the connecting plate 2 is not too long, which will not affect the assembly of the heat exchanger and can save material costs.

[0073] Exemplarily, the length of the straight portion 22 along the width direction of the main body 1 is T, and the thickness of the main body 1 of the side plate is t, and the relational expression: T > t is satisfied. By adopting this method, the structure of the connecting plate 2 is more stable.

[0074] In one embodiment, the arc portion 21 is provided with a notch 212, and the notch 212 communicates with the mounting groove 211.

[0075] When welding the mounting groove 211 of the arc portion 21 and the manifold 200, the solder can enter the notch 212 through the mounting groove 211. By using the notch 212 of the arc portion 21, the filling of the solder can be achieved, which is convenient for welding processing. At the same time, it can also provide a certain deformation margin for the welding process, effectively preventing excessive welding deformation.

[0076] Wherein, the notch 212 extends along the thickness direction of the main body 1, that is, the extending direction of the notch 212 is the same as the depth direction of the mounting groove 211. The notch 212 can cover the contact area between the mounting groove 211 and the manifold 200, increasing the connection strength between the mounting groove 211 and the manifold 200.

[0077] Specifically, along the thickness direction of the main body 1, the length of the notch 212 is less than or equal to the length of the connecting plate 2.

[0078] During processing, the notch 212 can extend along the thickness direction of the main body 1 from the side of the connecting plate 2 away from the main body 1, which is convenient for processing. The notch 212 can extend along the thickness direction of the main body 1 to the side surface of the main body 1 facing the connecting plate 2, avoiding affecting the structural strength of the main body 1.

[0079] In one embodiment, the notch 212 extends along the thickness direction of the main body 1. Along the thickness direction of the main body 1, the notch 212 penetrates through the end face of the connecting plate 2 on the side away from the main body 1. That is, the end face of the connecting plate 2 on the side away from the main body 1 is recessed towards the direction close to the main body 1 to form the notch 212, so as to improve the deformation ability of the connecting plate 2.
