Abstract

The utility model relates to a radiator technical field refers in particular to a buckled fin. The radiating fin structure is formed by overlapping and combining a plurality of radiating fin units, and each radiating fin unit is simultaneously provided with a buckling point and a buckling part buckled with the buckling point on the other radiating fin unit. After adopting above-mentioned structure, the fin adopts buckled combination, and is simple and convenient, can make up the size and the specification of fin according to actual need, and moreover, because the knot point itself is very thin, little, after buckle portion is buckled, the knot point directly forms the screens with the checkpost on another fin flat board, and the knot point need not inwards buckle promptly, keeps the knot point outside the radiating air duct, and this has just solved the windage problem that causes because of knot point buckle, makes the wind duct unblocked, strengthens the radiating effect of fin.

Description

A snap-fit heat sink

Technical field:

The utility model relates to the technical field of radiators, in particular to a snap-fit radiator.

Background technique:

The commonly seen heat sink is an integrally formed fin assembly, such as the CPU fan heat sink commonly used on computers and the heat sink on the motherboard. That is to say, at present, the specifications and sizes of general heat sinks are fixed, that is, the size of heat sinks and the number of fins cannot be changed according to needs, so the occasions or ranges used are relatively narrow and cannot meet certain the needs of specific occasions.

Utility model content:

The purpose of this utility model is to overcome the above-mentioned shortcomings of the existing products, and provide a new type of heat sink and heat sink unit, which adopts a fastening method, and the heat sink unit can be superimposed and combined into the required size, specification, etc. The heat sink makes the heat sink more widely used, and the assembly of the heat sink is also convenient and quick.

The utility model adopts the following technical scheme: the snap-fit heat sink is composed of several heat sink units superimposed and combined, and each heat sink unit is provided with buckle points at the same time and is interlocked with the buckle points on another heat sink unit The buckle part that fits.

The buckle point on the heat sink unit is located on the buckle part of the heat sink unit.

Specifically, the heat sink unit is a rectangular flat plate, the buckle part is formed on the outside of the side of the flat plate, and the buckle part forms a space, and the flat plate protrudes into the space, and the buckle The part can be bent around the side of the plate at a certain angle; there are buckle points extending outside the buckle parts, and the buckle points coincide with the spaces, that is, when the buckle parts on the two heat sink units are bent 90 degrees respectively, one cooling The buckle point on the fin unit can coincide with the space on another heat sink unit, and the card position is formed by the protruding card point of the flat plate.

The number of the buckle parts is four, which are symmetrically located on both sides of the flat plate, and the two buckle parts on one side are also connected as a whole by a rib. Similarly, the rib is also bent with the buckle part. fold. This is conducive to increasing the stability of the heat sink unit and the stability of the entire heat sink, so that the heat sink will not be easily deformed, and at the same time a fixed gap is formed between the heat sink units to better dissipate heat.

When making the heat sink unit and combination of the utility model, a certain number of heat sink units are designed in advance, put into the mold for stamping, bending, and fastening to directly form the finished heat sink combination, which greatly improves the production efficiency and effectively reduces the production cost.

After the utility model adopts the above-mentioned structure, the heat sink adopts a snap-fit combination, which is simple and convenient, and the size and specification of the heat sink can be combined according to actual needs. Moreover, because the buckle itself is very thin and small, after the buckle part is bent, the buckle point It directly forms a clamping position with the clamping point on another heat sink plate, that is, the clamping point does not need to be bent inward, and the clamping point is kept outside the cooling air duct, which solves the problem of wind resistance caused by the bending of the clamping point, making the wind The channel is unblocked, and the heat dissipation effect of the heat sink is enhanced.

Description of drawings:

Fig. 1 is the plane expansion diagram of the heat sink unit of the present utility model;

Fig. 2 is the three-dimensional schematic view of the heat sink unit of the present invention;

Fig. 3 is a three-dimensional structure schematic diagram of the utility model after assembly.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 3, the heat sink unit of the present invention is a rectangular flat plate 1, with four buckle parts 2 divided into two groups symmetrically formed on the outside of the side of the flat plate 1, and one group is connected by ribs 4 It is formed as a whole, and each buckle part 2 is formed with a rectangular space 20, and the plate 1 protrudes into the rectangular space 20 with a locking point 11, and the buckle part 2 can be bent at a certain angle around the side of the plate 1 There are buckle points 3 extending outside the buckle part 2 respectively, and the buckle point 3 coincides with the space 20, that is, when the buckle parts 2 on the two heat sink units are respectively bent by 90 degrees, the buckle point on one heat sink unit 3 can coincide with the space 20 on another heat sink unit, and form a locking position through the protruding locking point 11 of the plate 1.

When making the heat sink unit and the combination of the utility model, a certain number of heat sink units will be designed in advance, put into the mold for punching, bending, and fastening to directly form the finished heat sink combination.

To sum up, the utility model has the advantages of simple structure, convenient manufacture, high production efficiency, low cost, and good heat dissipation effect of the heat sink.

Of course, any obvious changes or equivalent modifications based on the principle and structure of the utility model shall fall within the protection scope of the utility model.
