Description
Technical field
The present invention is about the press formation method of heat pipe and radiating fin, especially refer to that the urgent and packing active force of a kind of tool side pressure is on average with the forming method of consolidation in conjunction with heat pipe and radiating fin one, use the urgent combination of improvement and make yield, make heat abstractor with high associativity and heat transfer efficiency.
Background technology
Known, the heat abstractor of the present electronic building brick that is applied to, especially require the heat abstractor of better cooling efficiency, it all is the heat abstractor that sees through heat pipe and radiating fin composition, do large-area thermal transpiration with the heat energy that quick transmission electronic building brick produces, heat pipe and radiating fin combine design and preparation method with direct reaction heat transfer efficiency and thermal transpiration speed, so good binding tight ness rating and preparation method are arranged, will promote the heat abstractor heat dissipation of composition.
As " associated methods of heat pipe and fin " patent of invention case of No. the 449514th, present Taiwan patent gazette, the emphasis of this patent case institute demand is to be coated with the last layer scolder on the composition surface that pipes such as heat are connected with fin; Heat pipe with after fin engages, is put into the vacuum furnace heating, make scolder produce the composition surface that capillarity is infiltrated pipe such as heat and fin, reach combination closely in the heating process fusing.
Again, " heat pipe and radiating fin manufacturing process " patent of invention case that the Taiwan patent gazette is I236337 number, the focusing on of this patent case institute's demand:
One, in the position that the heat pipe desire engages with radiating fin, plates the metal conductive medium layer;
Two, radiating fin being engaged in this heat pipe is coated with on the position of heat-conducting medium layer; And
Three, this heat-conducting medium layer heating after making it be melted between heat pipe and the radiating fin, is gone and cooled off.
Again, " radiating fin of minitype radiator and the associated methods of heat pipe and integrated structure " patent of invention case that No. the 518927th, the Taiwan patent gazette, the emphasis of this patent case institute demand is to solidify glue in the periphery coating of the heat pipe of minitype radiator; Before above-mentioned curing adhesive curing, utilize two groups of pressing sheets of two pressing moulds to insert two spaces between the radiating fin respectively, and simultaneously to the heat pipe direction near cramping, the bead of radiating fin is closely engaged with the heat pipe periphery.
But above-mentioned each patent case is all utilized heat-conducting medium or the curing glue of establishing with hot melt between heat pipe and radiating fin, after cooperating heating or pressuring method to reach heat pipe and radiating fin combines, all because of heat-conducting medium is covered with uniformly between heat pipe and radiating fin, or glue together uniformly, easily form gap affects combination and heat transfer effectiveness, moreover more there is chemical substance in heat-conducting medium and curing glue, easily causes the harm of human body and environment.
In addition, " associated methods of heat pipe and radiating fin " patent of invention case that the Taiwan patent gazette is I241156 number, the emphasis of this patent case institute demand is that an opening is set on radiating fin; Heat pipe is rotated, and makes radiating fin to the heat pipe translation; Behind the opening contact conductane pipe of radiating fin, keep the rotation of heat pipe, make to produce friction between heat pipe and the radiating fin, fricative heat makes friction surface be the plasticity molten state; Press the opening of heat pipe and radiating fin is welded together.But though the method does not have the harm of above-mentioned chemical substance to human body and environment, the plasticity that its different metal friction produces melts, and still has the uniformity problem of plasticity melt portions, easily forms gap affects combination and heat transfer effectiveness.
Moreover, the dealer is heat pipe other actual combination on the preparation method with radiating fin, be to adopt to wear the pressure combination, as shown in Figure 1, 2, mainly be that heat pipe 11 is installed in a heat-conducting plate 12 1 surfaces, and obtain a plurality of radiating fins 13 that are provided with through hole 14 at end face, promptly utilize this through hole 14 that radiating fin 13 is sheathed on the heat pipe 11 piecewise, to cooperate stamping parts and automatic facility (figure does not show), utilize piecewise and wear the compacting journey, make radiating fin 13 corresponding heat pipe 11 external diameters produce the combination of tight bundle; But aforementioned wearing compresses urgent preparation method, the compacting of wearing that removes is one by one done quite consuming time, what is more, every radiating fin 13 is in wearing the compacting journey, be subjected to facility punching press vibration and through hole thereof and make tolerance, all can influence the alignment and the packing effect of radiating fin 13 and heat pipe 11, easily each produces unconjugated gap 15 at diverse location, cause and make the fraction defective height, problem such as hot transfer efficiency and radiating effect are not good.
Summary of the invention
Main purpose of the present invention, be to solve above-mentioned tradition disappearance, avoid disappearance to exist, the present invention is with the press formation method redesign of heat pipe and radiating fin, utilization is in radiating fin surface through hole and the prominent wall design of ring thereof, cooperate simple tools framework, side pressure technology and assembly distortion combination process, heat pipe is combined with the urgent of radiating fin, improve its urgent combination and make yield, make heat abstractor, with the practical heat abstractor that the cheaper but high heat transfer efficient of user is provided and combines really with high associativity and heat transfer efficiency.
For reaching above-mentioned purpose, the press formation method of heat pipe of the present invention and radiating fin, this method comprises:
A plurality of radiating fins are provided;
Be formed into the few one prominent wall of ring that is provided with through hole in above-mentioned each radiating fin surface mirror, perhaps be provided with through hole, and have axially and/or the prominent wall of ring of profile groove radially, and be provided with fastener at two side end edges;
