Description

Technical Field

[0001] The utility model relates to the technical field of building exterior walls, in particular to a spliced heat dissipation fin. Background Technique

[0002] The heat dissipation fin structure is a heat dissipation element used for a radiator. Its main structural feature is composed of a series of thin sheets. By the shape and arrangement of the fins, the surface area of the radiator is increased and the heat conduction is accelerated. The heat dissipation fin structure is usually made of thin sheets of aluminum or copper. These thin sheets are curled and shaped into fins with certain elasticity and thermal conductivity. These fins are often shaped and processed in various ways according to various different specifications and requirements to meet different needs.

[0003] A heat dissipation fin structure with the Chinese authorized publication number of CN 220755321 U can fix the heat dissipation fin body on the heat conduction tube through fixing bolts, thus simplifying the production process, eliminating the bonding process, avoiding increasing the thermal resistance between the heat dissipation fin body and the heat dissipation base due to bonding, and improving the connection reliability.

[0004] However, there are still some deficiencies in the use of this patent. During the long-term use of the heat dissipation fins, dust and other impurities will accumulate between the heat dissipation fins, resulting in a reduction in the heat dissipation effect. The inability to dissipate heat will cause damage to electronic components. In this device, the connection of the heat dissipation fins is carried out by bolts. When it is necessary to replace and clean the heat dissipation fins, all the fins on the top of the fins to be replaced need to be removed for replacement, which is rather troublesome. Moreover, after the bolts are screwed and unscrewed many times, the bolts are prone to slipping threads. The bolt interfaces are exposed to the air for a long time and are also prone to oxidation and rust. In addition, most of the existing heat dissipation fins are rectangular in shape. During the convective heat dissipation process, the heat dissipation area is mainly determined by the size of the surface area of the heat dissipation fins. The larger the surface area, the better the heat dissipation effect. Therefore, heat dissipation fins with a larger surface area should be designed to increase their heat dissipation effect.

[0024] For the embodiments, please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] A spliced heat dissipation fin, including a base assembly 1, a fin assembly 2 is arranged on the side of the gasket 111. The thickness of the limiting plate 108 is set to 6 mm. The material of the limiting plate 108 is stainless steel. The material of the gasket 111 is silica gel. The inner wall of the limiting groove 105 fits with both sides of the fin body 201. The shape of the fin body 201 is set to a T shape. The material of the fin body 201 is set to copper.

[0026] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , it includes a base assembly 1. The base assembly 1 includes a base body 101. Ventilation grooves 109 are opened on both sides of the base body 101. A dust-proof net 110 is fixedly connected in the ventilation grooves 109. Two limiting plates 108 are fixedly connected to the inner bottom wall of the base body 101. A limiting hole 112 is opened on the side of the base body 101. A sliding rod 102 is slidably connected in the limiting hole 112. A reinforcing plate 103 is fixedly connected to the side of the sliding rod 102. A spring 106 is arranged on the side of the reinforcing plate 103. One end of the spring 106 is elastically connected to the reinforcing plate 103, and the other end of the spring 106 is elastically connected to the inside of the base body 101. A damping rod 107 is arranged inside the spring 106. A clamping strip 104 is fixedly connected to the side of the reinforcing plate 103. A limiting groove 105 is arranged on the side of the clamping strip 104. A gasket 111 is fixedly connected in the limiting groove 105.

[0027] Among them, by setting the base assembly 1, the installation and disassembly of the heat dissipation fin are realized, and the problem of inconvenient replacement and cleaning of the heat dissipation fin is solved. When it is necessary to disassemble and clean the heat dissipation fin, only need to gently pull the sliding rods 102 on both sides of the base body 101 to the two sides, so that the fin body 201 can move. Then pull the handle 204 to pull out the fin body 201, so as to realize the cleaning of the dust on its surface, avoid directly cleaning the dust on the heat dissipation fin body 201, improve the cleaning effect and cleaning efficiency of the heat dissipation fin body 201 with a large amount of dust, and at the same time ensure that the heat dissipation fin body 201 will not be damaged, and extend the service life of the heat dissipation fin body 201.

Grooves 203 are formed on both sides of the fin body 201. The setting of the grooves 203 increases the surface area of the heat dissipation fins.

Grooves 203 are formed on both sides of the fin body 201. The setting of the grooves 203 increases the surface area of the heat dissipation fins. In addition, the setting of the grooves 203 broadens the air flow channel, thereby further improving the heat dissipation effect of the entire heat dissipation fin structure. Moreover, the handle 204 provided at the top enables easy extraction of the fin body 201. When it is necessary to disassemble and clean the heat dissipation fins, only need to gently pull the sliding rods 102 on both sides of the base body 101 to both sides, so that the fin body 201 can move. Then pull the handle 204 to extract the fin body 201, so as to clean the dust on its surface, avoid directly cleaning the dust on the heat dissipation fin body 201, improve the cleaning effect and efficiency of the dust on the heat dissipation fin body 201, and at the same time ensure that the heat dissipation fin body 201 will not be damaged, and extend the service life of the heat dissipation fin body 201.
