In the heat sink, it plays a very important role is its heat sink. The heat sink part of the radiator is usually formed by stacking multiple heat sinks at intervals. Generally, each heat sink is in the shape of a flat plate, and is connected in series by using heat pipes, or vertically arranged on a heat conduction base. This type The number of heat sinks is often limited by the distance between each other, so the number of heat sinks cannot be increased, so that the heat dissipation area cannot be increased, and because the heat sinks are only connected by heat pipes or heat conduction bases, the heat is not easy to be evenly distributed.

Detailed ways

In order to enable your examiner to further understand the features and technical content of the utility model, please refer to the following detailed description and drawings of the utility model. be restricted.

Please refer to Fig. 1, which is a schematic plan view of the present utility model. The utility model provides a laminated heat sink set, the heat sink set 1 includes a first heat sink 10 and a second heat sink 11 formed by two continuous meandering bends; wherein:

The first heat sink 10 is a flat piece, which can be made of metal materials with good thermal conductivity such as copper and aluminum, and has two large-area flat surfaces on the upper and lower sides of the flat-lying state. 100, for the two second heat sinks 11 to bear respectively.

Based on the above, the two second heat sinks 11 are respectively fixed on the two surfaces 100 of the first heat sink 10, and each second heat sink 11 is a flexible metal sheet, and Wrinkles are formed in a continuous meandering manner; therefore, each second heat sink 11 has a plurality of heat sink portions 110 adjacent to each other at intervals due to bending, and between any two adjacent heat sink portions 110, that is, Connecting a bent portion 111, and by making each heat sink portion 110 in an upright position, each bent portion 111 on one side of the second heat sink 11 is in contact with the surface 100 of the first heat sink 10 Contact, and then glued with solder paste or thermal paste, or welded with solder, so that the two second heat sinks 11 are respectively fixed on the two surfaces 100 of the first heat sink 10, and constitute a described Heat sink set 1.

Therefore, by virtue of the above-mentioned structural composition, the laminated heat sink assembly of the present invention can be obtained.

Accordingly, as shown in FIGS. 2 and 3 , the utility model can be further applied to a heat pipe radiator 2. The radiator 2 includes a base 20 and a plurality of heat pipes erected on the base 20. 21. And a plurality of groups of the aforementioned cooling fin groups 1 pierced on each heat pipe 21, and each cooling fin group 1 is further separated by a first cooling fin 10 and stacked; wherein, each cooling fin group On the first heat sink 10 of 1, there are preset through holes 101 for the heat pipe 21 to penetrate, and the second heat sink 11 also cooperates with the through holes 101 on the first heat sink 10 to reserve a space for penetration 112, so that each heat sink group 1 can be inserted on the heat pipe 21, thus the heat dissipation of the heat sink 2 can be composed of each horizontal first heat sink 10 and each vertically arranged second heat sink 11. The fins have more heat dissipation area to help heat dissipation, so they have better heat dissipation efficiency. At the same time, if a side-blowing fan (not shown) can be further assembled, the wind flow field blown by the fan can also be changed, thereby greatly increasing its heat dissipation performance.
