The utility model relates to the technical field of heat sink structures, in particular to a heat sink that can be formed by overlapping and combining several identical heat sink units, and each heat sink can achieve the effect of tightly interlocking each other, and a certain heat sink can be formed between the stacked heat sinks. To form a good heat dissipation gap, and then form a new snap-fit type of heat sink that is stable and can continuously extend the heat dissipation area.

Background technique:

Generally known heat sinks are mostly integrally formed by aluminum alloy by extrusion or die-casting, so that the overall heat sink has several heat sinks arranged at appropriate intervals, so that the heat dissipation area is formed by the panels of each heat sink, so as to achieve The effect of heat dissipation; however, the integrated heat sink has a special shape and specification, which reduces its scope of application, and the fineness (number) of the heat sink of the overall heat sink is limited, which relatively directly affects the heat dissipation effect of the heat sink. Therefore, there are currently assembled radiators in the market. The overall radiator is formed by stacking and assembling heat sinks formed by metal plates. Increase the heat dissipation area of the radiator; however, because the heat dissipation fins of the assembled heat sink are almost stacked in a state of close contact, the heat dissipation space between the heat dissipation fins is insufficient, and the expected heat dissipation effect cannot be achieved. , can not meet the needs of customers.

To sum up, there are some areas that need to be improved in the current heat sink structure, and it is precisely for this purpose that the applicant created and designed the utility model.

Utility model content:

The technical problem to be solved by the utility model is to overcome the deficiencies of the current products, and to provide a combination of several identical heat sink units, and each heat sink is connected to each other, and a certain heat sink can be formed between the stacked heat sinks. To form a good heat dissipation gap, and then form a new snap-fit type of heat sink that is stable and can continuously extend the heat dissipation area.

The heat sink structure of the utility model is directly processed by stamping, and the structure of the buckle part, buckle point, fin and positioning groove of the heat sink is formed, so that the entire heat sink can be integrally processed and formed.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the new snap-fit heat sink is composed of several identical heat sink units, and each heat sink unit is provided with a buckle that can be bent The buckle part is provided with a buckle point, and the buckle part is provided with a buckle hole for the buckle point of a heat sink unit to fasten. The heat sink unit is also provided with a positioning groove for fixing buckle points.

The heat sink unit is a flat plate, and the buckle parts are formed at both ends of the plane, and the buckle parts can be bent at a certain angle around the two ends of the flat plate, and holes are provided along the bends, and the buckle parts are located at At the bending place, two convex points extend outward from the flat plate, and a positioning groove is formed between the two convex points; Pass the positioning groove of the previous heat sink unit, and its buckle part forms a positioning conflict with the two convex points of the previous heat sink unit, and the buckle point of the latter heat sink is bent to the inside of the clamping hole to meet the flat plate of the previous heat sink unit Form a slot.

The number of said buckle parts is 2, which are respectively symmetrically located at two ends of the flat plate.

A plurality of fins are also provided on the side of the flat plate. On the one hand, the stability of the heat sink unit is enhanced, and on the other hand, the heat dissipation effect is enhanced.

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 point itself is very thin and small, it is close to the other after bending 90 degrees. The inner side of the flat plate of the heat sink unit solves the problem of wind resistance caused by the buckle point bending, makes the air passage unblocked, and enhances the heat dissipation effect of the heat sink.
