Method for compositing cooling tube and fin piece and composition thereof

Abstract

The invention relates to a combining method of cooling tubes and fins and an assemblage thereof, wherein, the method mainly combines a plurality of fins and at least one cooling tube; the fins are mutually superimposed and provided with at least one through hole corresponding to each other; one side of each fin extends outside to form an extension wall along the circumference of the through hole; one side of each extension wall forms a first opening; furthermore, each fin forms a holding part provided with a second opening corresponding to the first opening; solder is injected into the holding part; the cooling tube is penetrated into the through hole; then, the fins are turned over so as to cause the first opening to turn upward; heating is carried out to melt the solder which flows to the first opening from the second opening and flows to a clearance between the cooling tube and the extension wall; combination is finished after cooling and the assemblage is formed.

Description

technical field [0001] The present invention relates to a heat dissipation device, in particular to a combination method of a heat dissipation pipe and a fin and its composition. Background technique [0002] In the heat dissipation device, taking the heat sink as an example, it is generally composed of a base and several upright fins arranged on the base, and the area in contact with the air is increased by these fins, thereby achieving better cooling effect. [0003] In addition, there is also a heat dissipation device that uses a combination of heat dissipation pipes and several fins. The main reason is that the heat dissipation pipes pass through the fins, and the heat from the heat source is quickly transferred to the heat dissipation device through the high temperature uniformity of the heat dissipation pipes. and other fins, and using the fins to increase the area in contact with the air can achieve an excellent heat dissipation effect. [0004] However, the combina...

Problems solved by technology

[0005] In the above method, the fins are stacked after the tin material is placed. In fact, the fins are in a hot melt state when the tin material is placed (Fig. 3 (b)). In order to prevent the tin material from running around when stacking, Usually, the stacking is started after the tin material is solidified. This situation will prolong the manufacturing time. In addition, the tin material is placed first before stacking and passing through the heat pipe, which may cause the tin material to fall out. According to the case According to Figure 3(d) of Fig. 3, when passing through the heat pipe, the solder material is located above the heat pipe, that is, the opening of the solder guide part is facing downward, and the solder material may fall out

If the tin material falls out, it will also affect the production yield
