Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 6 together, in the side plate 1 for a heat exchanger provided in this embodiment, the side plate 1 has a bending portion (not shown in the drawings), the bending portion is formed by bending the side plate 1 along the width direction (i.e., the Y direction in fig. 4), and the bending portion is provided with a notch 2 for releasing a partial stress generated by bending the side plate, so as to prevent the side plate from being deformed due to too large stress or too concentrated stress during the deformation process, which may not reach the standard, and damage the collecting pipe, the flat pipe, the fins, and the like, thereby ensuring the normal installation and use of the heat exchanger.

In this embodiment, in order to avoid the edge plate 1 from being deformed due to bending along the width direction, the notches 2 are disposed on the long side of the edge plate 1, the notches 2 are spaced along the length direction (i.e., the X direction in fig. 4) of the edge plate 1, and the center distance between two adjacent notches 2 and the size of the notch can be adjusted accordingly according to the width and length of the edge plate 1 and the bending radius of the bending portion.

In this embodiment, in order to better reduce or release the bending stress of the edge plate and ensure the strength of the edge plate, the center distance between two adjacent notches 2 may be set to be greater than or equal to the width of the edge plate 1. The plurality of notches 2 may be arranged at the bending portions of the side plate 1 at equal intervals, or may be arranged at the bending portions of the side plate 1 at different intervals.

In addition, in order to ensure the strength of the side plate, the notch 2 can be arranged on one long edge of the side plate 1, the long edge can be the long edge on the inner side of the bending part of the side plate 1, and the opening direction of the notch 2 faces to the inner side of the bending part of the side plate 1; the long side may be a long side outside the bent portion of the side plate 1, and the opening direction of the notch 2 may face the outside of the bent portion of the side plate 1.

In this embodiment, a specific structure of the edge plate will be described by taking as an example that the notch 2 is provided on the long side of the inner side of the bent portion of the edge plate 1, and the opening direction of the notch 2 is directed toward the inner side of the bent portion of the edge plate 1.

Referring to fig. 4 and 5, in the embodiment, the notch 2 has an arc section 21 and a straight section 22 extending from the end of the arc section 21 toward the opening of the arc section 21, and the straight section 22 extends to the long side of the side plate 1. So set up, when the sideboard was bent along width direction, breach 2 was drawn close to the center, because of the existence of breach 2 to can avoid the sideboard to bend and produce stress.

In addition, the notches 2 can be arranged in an axial symmetry mode, and the axes of the notches 2 are parallel to the width direction of the side plate 1.

It should be noted that the arc section 21 disposed in the notch 2 can prevent a sharp part from occurring at a local part of the notch 2, so that the edge plate does not introduce extra stress due to the notch.

In addition, in the preferred scheme, the breach can be the horn shape setting, guarantees that the inboard of the portion of bending can not take place to extrude and lead to stress to produce when the sideboard is bent.

It should be noted that the notch 2 may be configured in other shapes as long as it can satisfy that when the edge plate is bent, the side edge of the notch has enough space to approach to the middle, and stress is not generated due to contact extrusion.

In order to reduce or release the bending stress of the edge plate, in this embodiment, the depth of the notch 2 is greater than half of the width of the edge plate body.

In another embodiment, the sideboard 1 may further comprise a first rib 4 and/or a second rib 5 protruding towards the flat tube 3. Wherein, first fin 4 is located the both ends of sideboard 1 and is close to the position of pressure manifold 6, and just first fin 4 runs through sideboard 1 along the width direction of sideboard 1, and the length of first fin 4 is more than or equal to the width of sideboard 1. Thus, when the edge plate 1 is welded to the header 6, the first protruding rib 4 can effectively block the composite layer on the header 6 from flowing to the edge fin (not shown), so as to prevent the fin on the edge fin close to the header 6 from being corroded. The second convex rib 5 is arranged between the bending parts of the first convex rib 4 and the side plate 1 or is far away from the bending part of the side plate 1, the second convex rib 5 extends along the length direction of the side plate 1, and the second convex rib 5 can be used for preventing the side fin and the side plate from being subjected to cold joint, so that the welding quality of the side fin and the side plate is ensured.

It should be noted that the length of the second rib 5 is determined according to the length of the side plate 1, and when the length of the side plate 1 is longer, the length of the second rib 5 can be set to a larger value; or a plurality of second ribs 5 having a shorter length may be arranged at intervals along the length direction of the edge plate 1.

The utility model also provides a heat exchanger, including pressure manifold, flat pipe and above-mentioned sideboard, the sideboard is installed in the side of heat exchanger and is on a parallel with flat pipe, and the sideboard tip carries out welded fastening with the pressure manifold. When the heat exchanger is bent and installed, the arrangement of the notch in the bending part of the side plate can prevent the side plate from generating stress concentration when the side plate is bent, so that the conditions that the side plate is too large in stress or excessively concentrates to lead to deformation not reaching the standard, damage the collecting pipe, the flat pipe, the fins and the like in the deformation process are avoided, and the normal installation and use of the heat exchanger are further ensured.
