Abstract

The utility model relates to a combined heat dissipation fin, which is a plate body cut from heat-conducting materials such as aluminum, copper or graphite. One side of the plate body is punched with a plurality of spaced openings, and the other side of the plate body is provided with a connecting portion. The surplus material of the plurality of openings is bent upward to form a plurality of heat dissipation fins. The openings of the plate body are interlaced with the openings of another plate body so that the two plates can be inserted into each other to form an integral heat dissipation fin. The connecting portion can also be enlarged in size so as to be directly placed on different photoelectric heating components for use, thereby improving the heat dissipation applicability of the integral heat dissipation fin. The complete heat dissipation fin formed by inserting the two plates into each other can effectively reduce the manufacturing cost, and can be bent and attached according to the appearance of the electronic heating component, thereby greatly improving the heat dissipation efficiency.

Description

Combined cooling fins

technical field

The utility model relates to a combined heat dissipation fin, in particular to a heat dissipation fin which can increase the contact area with an electronic heating component and can also be bent and changed according to the shape of the photoelectric heating component.

Background technique

With the advancement of technology, the execution speed of electronic devices (such as computer hosts, personal digital assistants, etc.) is getting faster and faster, but the temperature generated in electronic devices is also getting higher and higher. The temperature is effectively dissipated outside the system to maintain the operation of each component in the electronic device below the allowable temperature. The heat dissipation system has become an indispensable main part of the current electronic device.

Please refer to shown in Fig. 1, it is a stereogram of a kind of known radiator, it punches the radiator 10 that several roads are bent shape by metal materials such as aluminum or copper, and this radiator 10 can be combined with an electronic heating element ( Figure omitted) gluing, so as to help the temperature generated by the electric heating components to be effectively dissipated outside the system, so as to maintain the operation of the electronic heating components under the allowable temperature.

However, the above-mentioned known heat sink 10 is separated by several grooves 101 , so the area glued to the electronic heating element is reduced, thereby reducing the heat dissipation effect of the heat sink 10 .

Please refer to Fig. 2, which is a three-dimensional exploded view of another known radiator, which is punched out of metal materials such as aluminum or copper into several pieces of "匚"-shaped boards 111 and concave and convex matching buckles. 112 combined radiator 11, the radiator 11 can be glued with an electronic heating component (not shown), so as to help the temperature generated by the electronic heating component to be effectively dissipated outside the dry system, so as to maintain the electronic heating component within the allowable temperature down operation.

However, although the above-mentioned known heat sink 11 increases the bonding area with the electronic heating component, because the concave and convex buckle parts 112 are engaged with each other, the overall heat sink 11 cannot be bent. With more and more diversification, the heat sink 11 cannot be bent due to electronic heating components such as heat pipes, which reduces the usability of the heat sink 11 .

Therefore, it can be seen from the above that the above-mentioned known combined heat dissipation fins obviously have inconvenience and disadvantages in actual use, and can be improved.

Contents of the invention
