Above-mentioned commonly using has its problem to exist on the implementation, because around these tin cream 13 solids such as grade must be coated in the open-work 111 of each radiating fin 11 and the protuberance 112 in advance, or coat on the heat pipe 12 in advance, and when heat pipe 12 runs through the open-work 111 of radiating fin 11, be subjected to the crowded of engaging space, make part tin cream 13 solids such as grade be extruded, and be covered in a slice radiating fin 11 outer surfaces of outermost, and the tin cream 13 that part is not extruded is when fusion, then be difficult for evenly being covered with between the open-work 111 of heat pipe 12 and radiating fin 11, cause part tin cream 13 to overflow protuberance 112 outsides (showing) as Fig. 3 a in each radiating fin 11, cause the driving fit situation between radiating fin 11 and the heat pipe 12 poor, and produce and loosening both to be integrated, cause heat conduction usefulness not good, and not attractive in appearance.

When fluid is flowed through 11 of this each radiating fins, increase the flow resistance of fluid because of this protuberance 112, and then reduce amount of flow and radiating effect is had a greatly reduced quality, it is required not to be inconsistent present high-power electronic building brick in fact.

Because above-mentionedly commonly use every shortcoming that product are derived, the inventor of this case exhausts its intelligence then, is innovated improvement to be engaged in the sector experience for many years, to concentrate on studies, finally successfully this part heat radiation fin structure case is finished in research and development, is the utility model that a tool effect is promoted.

Summary of the invention

For effectively solving the above problems, main purpose of the present utility model provides a kind of depressed part that is formed with at least one toward side depression at least one radiating fin, this depressed part structure is established one and is inserted the space for the heat-conducting medium setting, and in depressed part, offer a perforation that is slightly larger than the heat pipe caliber, wear for heat pipe, the utility model is able to ccontaining heat-conducting medium by this depressed part, and the heat-conducting medium that adds this fusing in man-hour evenly is covered with between this heat pipe outer surface and perforation inner edge.

The utility model relates to a kind of heat radiation fin structure, this radiating fin body forms at least one depressed part toward side depression, this depressed part structure is established one and is inserted the space, for a heat-conducting medium setting, and in this depressed part, offer a perforation that is slightly less than this depressed part and wear at least one heat pipe, one flanging is to extend around this perforated edge and toward same side, is evenly filled up via fusing by this heat-conducting medium to be covered with between heat pipe outer surface and perforation inner edge and flanging.

The beneficial effect that the utlity model has: owing to insert the external diameter of the radial extension in space greater than heat pipe, so this inserts crowded can not be subjected to heat pipe and run through this perforation time of heat-conducting medium that the space is provided with, therefore can be complete remain in inserted in the space, being melted mobile uniformly perforation inner edge and the heat pipe outer surface that is covered with in each radiating fin, having been strengthened radiating effect greatly.
