Therefore, both sides of the radiating fin group form a complete plane, and the radiating fin group has a larger radiating area so as to increase the heat radiation, and all the radiating fins are more stably combined and can not be separated randomly.

Description

Combination structure of heat sink

technical field

The utility model provides a heat sink structure, especially the heat sink can exert a better heat dissipation effect, and the heat sink combination can effectively improve the joint stability.

Background technique

As shown in Figure 1, the structure of conventional heat sink 10 is mostly a thin sheet, and its top 11 is provided with several gaps 111, and the bottom 12 is provided with a horizontal sheet 121 at the moderate position, and at the top and bottom 11, 12 two parts Angle pieces 13 protrude from the front and rear edges respectively, and are used to connect the angle piece 13 of the previous heat sink 10 to the angle piece 13 of the next heat sink 10 when the heat sink 1 is assembled with the heat sink 1 .

As mentioned above, after the conventional heat sink 10 is assembled, although it can achieve the effect of heat dissipation, the number of gaps 111 and the horizontal fins 121 and the corner fins at the top, bottom 11, and 12 of the assembled heat sink 10 will The structural design of 13 makes the overall heat sink group present an uneven state up and down, forming a number of pores, making the air flow unsmooth, resulting in a reduction in the contact heat dissipation area of the heat sink 10, increasing the wind resistance, and affecting the installation on the heat sink. The air volume of the heat dissipation fan on the group, thereby reducing the heat dissipation effect of the heat sink 10.

Furthermore, the stability of the aforementioned combined design is very weak, when the two ends of the heat sink are pulled towards the opposite direction. For the heat sink 10 where the stress is concentrated, the corner piece 13 at one end will be separated from the corner piece 13 of the adjacent heat sink 10, and when one end is separated, the corner piece 13 at the other end will also be separated from the corner piece 13 of the adjacent heat sink 10 13, so that the heat sink 10 is immediately dismembered and separated.

Therefore, in view of the lack of the combination structure of the above-mentioned conventional heat sinks, the inventor has worked out a more practical and wide-ranging application with years of experience and expertise in related industries, and with the spirit of research, innovation and excellence. A combination structure of heat sinks that is wider and in line with industrial application value.

Contents of the invention

The purpose of the present invention is to provide a combination structure of heat sinks, which overcomes the above-mentioned defects of the traditional structure, enables the heat sinks to exert a better heat dissipation effect, and effectively improves the combination of heat sinks with stability.

In order to achieve the above-mentioned purpose, the utility model provides a combination structure of heat sinks, which is composed of several heat sinks, each of which has a body plate and a relative vertical portion extending from both sides of the body plate, and It is vertically intersected with the body plate, and its feature is that the vertical part includes one or more slots, and there is a convex part in the slot, the length of the convex part is equal to the length of the vertical part, and the front end of the convex part faces outwards on both sides The expansion has a buckle for being folded into the draw-in groove of the adjacent heat sink to form a fastening connection.

Wherein, the length of the convex portion is the same as the length of the vertical portion extending from both sides of the body plate.

Beneficial effects of the utility model: To sum up the above, the combination structure of the cooling fins of the utility model obviously has a better heat dissipation effect than the conventional combination structure of cooling fins, and effectively improves the bonding stability between adjacent cooling fins.

In order for the examiner to have a better understanding of the purpose, features, and functions of the present utility model, a preferred embodiment is hereby given in detail with reference to the drawings as follows:

Detailed ways

Please refer to Fig. 2 and shown in Fig. 3, the utility model is mainly made up of several cooling fins 20, and its each cooling fin 20 has a body plate 2 and a relative vertical portion 3, and this vertical portion 3 is formed by the body plate 2, extending from both sides, and perpendicular to the body plate 2, wherein the vertical part 3 includes two card slots 31, and a convex part 32 is formed in each of the card slots 31, and the front ends of the convex parts 32 expand outward to both sides. A buckle 321 is defined, so that when the heat sinks 20 are combined, the buckle 321 of the protrusion 32 is punched to be folded into the slot 31 of the adjacent heat sink 20 to form a buckled heat sink group.

As shown in Fig. 3 and Fig. 4, because the length extending from the two sides of the body plate 2 by the vertical portion 3 is equal to the length of the convex portion 32, when the cooling fins 20 are connected to each other, the vertical portions 3 are abutted against each other. A distance of 4 is formed, and the buckle 321 that expands the protrusion to both sides is correspondingly located on the slot 31 of the adjacent heat sink 20, so when the buckle 321 of the protrusion 32 is punched, the buckle 321 is folded Inserting into the slots 31 of the adjacent heat sinks 20 to form buckles, so that the heat sinks 20 can be stacked together stably.

Continuing from the above, after the fins 20 of the present utility model are snapped and connected to each other, the two sides of the fins 20 form a relatively complete plane, and have a larger heat dissipation area to increase heat dissipation. Taking the structure shown as an example, there are four sets of protrusions 32 on two adjacent heat sinks 20, which provide eight buckling points, thereby strengthening the joint stability between adjacent heat sinks 20 and greatly improving the external force. resistance.
