Description

Technical Field

[0001] This utility model relates to the field of heat dissipation fin technology, and in particular to a corrugated integral heat dissipation fin. Background Technology

[0002] Heat sink fins are heat transfer elements used in heat exchangers. They typically work in conjunction with heat exchange tubes. A low-temperature medium flows through the heat exchange tubes, exchanging heat with a high-temperature medium outside the tubes to achieve a cooling effect. The heat sink fins are metal sheets used to increase thermal conductivity during heat transfer, thereby increasing the surface area for heat exchange and improving efficiency. However, current industry demands for higher heat exchange efficiency from heat sink fins are constantly increasing, and simple heat sink fins are no longer sufficient to meet these requirements. Utility Model Content

[0003] This utility model discloses a corrugated integral heat dissipation fin, which mainly solves the problem that the heat exchange efficiency of traditional heat dissipation fins cannot meet the requirements.

[0004] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0005] This utility model provides a corrugated integral heat dissipation fin, comprising multiple fin bodies stacked on top of each other. The fin bodies are provided with multiple inclined first corrugated areas and second corrugated areas. The first corrugated areas and the second corrugated areas form a continuous corrugated structure. Along the direction of the first corrugated area or the second corrugated area, the fin bodies have multiple pitted areas, and the fin bodies are provided with multiple protrusions at the positions corresponding to the pitted areas.

[0006] In one embodiment, the thickness of the protrusion is smaller than the thickness of the fin body.

[0007] In one embodiment, along the direction of the first corrugated area, a plurality of heat exchange tube holes are penetrating the fin body, and the heat exchange tube holes are staggered with the pitted area along the second corrugated area.

[0008] In one embodiment, a plurality of water film holes are provided through the fin body along the direction of the second corrugated region.

[0009] In one embodiment, the water film pores and the pitted areas are arranged alternately.

[0010] In one embodiment, the first corrugated area and the second corrugated area are arranged alternately.

[0011] In one embodiment, the upper and lower edges of the fin body are a third corrugated area, the third corrugated area is a continuous corrugated structure, and the amplitude of the corrugated structure of the third corrugated area is greater than the corrugated structure formed by the first corrugated area and the second corrugated area.

[0012] The advantages or beneficial effects of the above technical solution include at least the following: by setting a first corrugated area and a second corrugated area with a continuous corrugated structure on the fin body, setting a pitted area on the first corrugated area or the second corrugated area, and setting protrusions on the pitted area, the surface area of ​​the fin body can be increased, thereby increasing the heat exchange efficiency of the fin body; at the same time, it can form corrugated gaps between adjacent fin bodies to prevent blockage between the gaps, so as to facilitate cleaning.

[0022] It should be noted that the terms "a" and "a plurality of" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0023] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0024] See Figure 1 and Figure 2 This utility model provides a corrugated integral heat dissipation fin, comprising multiple stacked fin bodies 1. Each fin body 1 has multiple inclined first corrugated areas 11 and second corrugated areas 12, forming a continuous corrugated structure. Along the direction of the first corrugated area 11 or the second corrugated area 12, each fin body 1 has multiple pitted areas 13, and each fin body 1 has multiple protrusions 131 corresponding to the positions of the pitted areas 13. Adjacent fin bodies 1 can be stacked in the same direction or in opposite directions.

[0025] By adopting the above structure, by setting a first corrugated area 11 and a second corrugated area 12 with a continuous corrugated structure on the fin body 1, setting a pitted area 13 on the first corrugated area 11 or the second corrugated area 12, and setting a protrusion 131 on the pitted area 13, the surface area of ​​the fin body 1 can be increased, thereby increasing the heat exchange efficiency of the fin body 1; at the same time, it can form corrugated gaps between adjacent fin bodies 1 to prevent blockage between the gaps and facilitate cleaning.

[0026] The thickness of the protrusion 131 is smaller than the thickness of the fin body 1. In practical applications, the protrusion 131 is formed by stamping, so that the thickness of the protrusion 131 is smaller than the thickness of the fin body 1, thereby improving the heat exchange efficiency of the protrusion 131.

[0027] Along the direction of the first corrugated region 11, a plurality of heat exchange tube holes 14 are penetrating the fin body 1. The heat exchange tube holes 14 and the pitted region 13 are staggered along the second corrugated region 12. The heat exchange tube holes 14 are used to install heat exchange tubes. In practical applications, the staggered arrangement of the heat exchange tube holes 14 and the pitted region 13 can make the pitted region 13 and the heat exchange tube holes 14 evenly distributed in the first corrugated region 11, thereby making the heat exchange of the fin body 1 more uniform.

[0028] Along the direction of the second corrugated zone 12, multiple water film holes 15 are provided on the fin body 1. In practical applications, the water film holes 15 enable the medium to form a water film and evaporate when it passes through the water film holes 15, thereby improving the cooling effect.

[0029] The water film holes 15 and the pitted area 13 are staggered (not shown in the figure). In practical applications, staggering the water film holes 15 and the pitted area 13 allows the pitted area 13 and the water film holes 15 to be evenly distributed in the second corrugated area 12, thereby making the heat exchange of the fin body 1 more uniform.

[0030] The first corrugated area 11 and the second corrugated area 12 are arranged alternately. In practical applications, the alternating arrangement of the first corrugated area 11 and the second corrugated area 12 can make the heat exchange of the fin body 1 more uniform.

[0031] The upper and lower edges of the fin body 1 are the third corrugated areas 16. The third corrugated areas 16 have a continuous corrugated structure, and the amplitude of the corrugation structure in the third corrugated areas 16 is greater than that of the corrugated structure formed by the first corrugated areas 11 and the second corrugated areas 12. In practical applications, the continuous corrugated structure of the third corrugated areas 16 allows the medium to enter the corrugated gaps between adjacent fin bodies 1 more smoothly, thus facilitating heat exchange in the fin bodies 1.

[0032] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
