Problems solved by technology
[0006] However, the disadvantages of traditional fins are: the arc section is composed of a single arc surface with a relatively small radius, so the contact surface between the arc section and the flat tube is small, resulting in poor heat transfer, that is, finning of the fins low efficiency
Traditional fins cannot solve the problem of water accumulation in the above three parts well, resulting in a decrease in the performance of the heat exchanger

Embodiment Construction
[0051] The present invention will be described in detail below by taking a parallel flow heat exchanger as an example. Here, it should be pointed out that the embodiments of the present invention are only illustrative, which are only used to illustrate the principle of the present invention rather than limit the present invention. It is obvious to those skilled in the art that the fins of the present invention are not limited to use in parallel flow heat exchangers, but can also be used in various other heat exchangers using fins.
[0052] In the following description, structural components that are the same as or similar to those of the related art will be given the same reference numerals, and descriptions thereof will be simplified.
[0053] see first Figure 4 ,in Figure 4 A is a partial schematic diagram, illustrating a heat exchanger using fins according to an embodiment of the present invention, and illustrating the specific composition of an arc segment.

The present invention discloses a fin for a heat exchanger, the fin comprises a plurality of fin plates (10) which are adjacent to one another, each of the fin plates (10) is formed with louvers (20); and a connecting portion which connects adjacent fin plates at an end of the adjacent fin plates. The connecting portion comprises a middle curved section (31) and side curved sections (32) located on the sides of the middle curved section (31), and the curvature radius of the middle curved section (31) is larger than the curvature radius of the side curved sections (32). With the technical solution of the invention, since the contact area between the flat tubes and the fin increases, the fin efficiency is increased and thus the heat exchange performance of the heat exchanger is enhanced.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a fin used for the heat exchanger. Background technique [0002] Heat exchangers are common components used in refrigeration systems and air-conditioning systems. They can be divided into condensers and evaporators according to their functions. In order to improve the heat transfer performance of the heat exchanger, among other things, the heat exchanger is usually provided with fins. [0003] Figure 1A and 1B A conventional fin used in a parallel flow heat exchanger is illustrated, where Figure 1A is the planar view of the fin, Figure 1B is along Figure 1A Sectional view taken along line B-B in . [0004] The fins are made of materials with good thermal conductivity, such as aluminum alloy, and are formed by bending the aluminum alloy plate. Such as Figure 1A As shown, the fin 1 of the heat exchanger includes a plurality of straight plate segments 10 adjacent to each other (for simpl...
