Abstract
The invention relates to a method for tightly combining a heat radiation fin with a heat pipe. A groove is formed on one side edge of the fin, positioning parts are further convexly arranged on two sides of the groove respectively, the heat pipe is combined after being placed into the groove, and a pressing die is used for pressing the fin so as to enable the two positioning part to bend and deform inwards, enable a notch of the groove to deform slightly and contract and further press and clamp the heat pipe; and another embodiment is that, a guide trench is further molded on the outer edge of each positioning part, the pressing die is also provided with convex parts corresponding to the guide trenches, when the pressing die is used for pressing, and the convex pars can be just embedded in the guide trenches, thereby enabling the parts between the positioning parts and the groove to deform and contract, further pressing and clamping the heat pipe, simplifying the procedure for fixing the heat pipe with the fin, and ensuring the close joint between the heat pipe and the fin.
Description
Technical field
The present invention relates to relevant with radiator, particularly relevant with the radiator that contains heat pipe and fin, with and method for tightening.
Background technology
Continuous lifting along with semiconductor subassembly and electronic equipment speed and usefulness; Its caloric value also is and the day multiplication that also when the river rises the boat goes up for the radiating requirements of relative semiconductor subassembly or light-emitting diode (LED) light fixture etc., on the other hand; Electronic equipment is invariably towards compact development; The accommodation space that makes radiator to occupy is further limited, and therefore, the usefulness of radiator faces great challenge.
For in limited volume, bringing into play maximum heat dissipation, radiating fin is many must to be made up with heat pipe, conducts with accelerated heat through the quick conductive force of heat pipe.Heat pipe needs and each fin fluid-tight engagement, and performance conductive force really only can only form contacting of wire between heat pipe and the fin; The practice of general convention is used the composition surface of scolder welding heat pipe and fin; But the not only not environmental protection and very loaded down with trivial details of this kind welding method for making not only must apply the scolder welding on each fin, need heat again to make solder fusing; Moreover flowing of liquid solder also is difficult to keep evenly; Often cause the scolder thickness to differ, in addition can be gapped situation take place, be difficult to guarantee tight contact the between heat pipe and fin.So for the producer, make the radiator utmost point with this kind method for tightening and do not meet economic benefit.
Again, commonly use the combining structure of the fin and the heat pipe of radiator, like Taiwan novel M268111 patent case; Mainly form the through hole that the heat supply conduit is implanted in fin; Heat pipe inserts in the through hole, through the deformation of a molding tool punching press heat pipe, and tightly ties one with fin; In the preceding paragraph structure,, when the mould punching press, this copper platinum lamination is come off and influence heat and pass usefulness because the inwall of heat pipe is a copper platinum lamination.
Summary of the invention
Main purpose of the present invention promptly is to provide a kind of radiating fin and heat pipe method for tightening, and the completion heat pipe that it can be quick and easy engages with closely fixing the reaching of fin, significantly promotes production efficiency.
Another object of the present invention promptly is to provide a kind of radiating fin and heat pipe method for tightening, and it can guarantee tight contact the between heat pipe and fin, and the homogeneity of engagement state obtains effectively to promote.
For reaching above-mentioned purpose, a preferred embodiment of the present invention is to offer a groove in a side of fin, and the adaptive space of corresponding heat pipe two inwalls of groove is not more than heat pipe; Heat pipe is inserted in the groove packing engages, or further be convexly equipped with a location division respectively in the both sides of groove, treat that heat pipe is inserted groove after; With pressing mold to the fin punching press; Make the deformation that curves inwardly of this two location division, and the notch place of groove is out of shape a little and in contract and then urgent strangulation heat pipe.Another kind of embodiment then is in further moulding one guide channel of this location division outer rim; And pressing mold also is provided with the protuberance corresponding to this guide channel, and when with the pressing mold punching press, its protuberance just embeds in the guide channel; Make in the part distortion between location division and groove and contract; And then urgent strangulation heat pipe, with the fixed routine of simplification heat pipe and fin, and can guarantee fluid-tight engagement therebetween.
