Abstract

The invention relates to a method for combining a fastening type fin set and heat pipes and a structure thereof. The method comprises the following steps of: providing at least one heat pipe and a plurality of fins, wherein all the fins are respectively provided with a through hole and a fastening structure; providing a press tool with raised lines; sequentially pressing and sleeving the heat pipes in the through holes of the fins; and finally, pressing the overlapped fastening structures of all the fins by the raised lines so as to ensure that the fastening structures of two adjacent fins are mutually clamped to achieve the combination of the fins and the heat pipes and prevent the fins sleeved at the tail ends of the heat pipes from loosening or falling off. The manufacture process of the invention cannot generate pollution and conforms to environmental protection requirement.

Description

Fastening type fin group and heat pipe associated methods and structure thereof

Technical field

The present invention is relevant with radiator, is particularly to the associated methods of a kind of heat pipe and fin.

Background technology

General electronic building brick all can produce heat when operating, particularly recent progress along with science and technology, after the function of electronic product and performance greatly promote, its inner heat that produces increases especially significantly, for this reason, big multiple electronic modules all need set heat abstractor, keeps the normal operation of electronic building brick so as to the Control work temperature; Moreover, be assemblied in the heat abstractor of computer module now, generally by the combination of different radiating subassemblies, as mutually combining between the assemblies such as radiating fin, heat pipe and temperature-uniforming plate, radiator fan and heat-conducting seat, so that the performance of the efficient of radiating subassembly is to ultimate attainment; Wherein, be equipped with the radiator of heat pipe in the radiating fin that multi-disc is repeatedly put layer by layer, be common a kind of heat abstractor.

The associated methods of heat pipe and radiating fin is broadly divided into two kinds, and the mode that the one utilization is forced into after establishing a perforation on each radiating fin, is overlapped several dissipation fins seriatim and to be against the heat pipe periphery; Yet, because the end of heat pipe is generally a draw section, the caliber of this draw section is less than this piercing aperture, so the end of heat pipe is not closely to amplexiform mutually with radiating fin, cause the radiating fin that is sheathed on the heat pipe end easily loosening or come off, and then can't keep the outward appearance and the integrality thereof of radiator.

Please join Fig. 1, show the combination of another kind of heat pipe and radiating fin; Each radiating fin 11a is provided with fastening structure 12a and perforation 13a, the periphery of this perforation 13a is provided with a connecting hole 14a in addition, with the mutual fastening of adjacent radiating fin 11a to form this radiating fin group 10a, after penetrating this heat pipe 20a among this perforation 13a, because the combination that this radiating fin group 10a and heat pipe 20a join for pine, so need in this connecting hole 14a, to insert welding rod 30a in addition, treat after processing such as soldering and reprocessing, promptly to finish the processing that heat pipe 20a is incorporated into this radiating fin group 10a; Yet under the requirement of processing usefulness and cost, known soldering processing not only takes takes a lot of work, and its manufacturing process produced pollution, also environment is caused burden and is not inconsistent required.

In view of this, the inventor is for improving and solving above-mentioned disappearance, is that the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the present invention of above-mentioned disappearance finally.

Summary of the invention

A main purpose of the present invention, be to provide a kind of fastening type fin group and heat pipe associated methods, earlier heat pipe is forced in the fin, press each fin fastener structure again, the fastening structure that makes wantonly two adjacent fins is clip mutually, reach the combination of fin and heat pipe whereby, it is loosening or come off to prevent to be sheathed on the fin of heat pipe end.

In order to reach above-mentioned purpose, the present invention is a kind of fastening type fin group and heat pipe associated methods, and its step system comprises: at least one heat pipe a) is provided; B) provide plurality of fins, respectively this fin has a perforation and a fastening structure respectively; C) provide a pressing element with a raised line; D) will be respectively this fin with urgent in regular turn this heat pipe that is sheathed on of its perforation, and make respectively that this fin repeatedly connects mutually with its fastening structure; E) in this d) after the step, press the respectively fastening structure of this fin with the raised line of this pressing element, and the mutual clip of wantonly two adjacent fins is connected.

A further object of the present invention is to provide a kind of fastening type fin group and heat pipe associated methods and structure thereof, consumption worker's soldering processing when not costing, and its processing do not produce pollution, and environment is not caused and can bear and compliance with environmental protection requirements.

In order to reach above-mentioned purpose, the present invention is the structure that a kind of fastening type fin group combines with heat pipe, comprising: at least one heat pipe; And plurality of fins, respectively this fin has a perforation and a fastening structure respectively, urgent this heat pipe that is combined with in this perforation, these fastening structures are for repeatedly connecing mutually and having a lug respectively, this lug offers a draw-in groove and is formed with the folder limit of pulling in the side of this fin, and this lug clip is pulled between the limit in two folders of the first two adjacent fin.

Compared to known technology, because fin of the present invention has fastening structure, be sheathed on the heat pipe plurality of fins is urgent earlier, after pressing fastening structure with pressing element again, can make the mutual clip of wantonly two adjacent fins, can make whereby that the fin that is incorporated into heat pipe end (draw section) is unlikely to be become flexible, come off, and its manufacturing process need not use scolding tin processing, not only simple material saving and do not produce environmental contaminants increases the practicality of the present invention and the feature of environmental protection.
