Abstract
A heat radiator with better parallelism features that a supporting unit (auxiliary fixture) is arranged in the heat radiator and its making method, and multiple locating slots are arranged at bottom edge of said supporting unit for clamping the top edges of multiple fins.
Description
Technical field
The present invention relates to a kind of manufacture method that produces heat abstractor, auxiliary fixture and the heat abstractor of preferred parallel degree, especially finger is a kind of can provide fin apical margin good supporting, make fin can not produce deflection, make the fin regularity good, and the depth of parallelism is good, and then make air-flow average, the manufacture method of heat abstractor, auxiliary fixture and heat abstractor that radiating efficiency is preferable.
Background technology
Along with computer industry develops rapidly; the execution speed of chip, CPU pyrotoxins such as (CPU) is more and more fast; the caloric value of relative pyrotoxin is also more and more high; for the high temperature that pyrotoxin produced is discharged in the external world; make pyrotoxin can in the permission temperature under normal operation; usually can be attached on the excessive hot surface of pyrotoxin to have the larger area radiator, utilize a plurality of fins of radiator to assist heat radiation.
Known radiator mostly has a tabular pedestal and a plurality of fin, pedestal and a plurality of fin are to make with copper material or aluminium, pedestal and a plurality of fin desire in conjunction with the time, must with modes such as soldering welding one by one the fin root edge is fixed in base top surface, make a plurality of fins being arranged on the pedestal at interval.In addition, known radiator is also arranged, in advance fin fastener is linked together, in modes such as soldering weldings the fin root edge is fixed in base top surface again.The manufacture method of above-mentioned known radiator is because suitable time-consuming of the combination of pedestal and fin causes the increase of manufacturing cost.
Other has a kind of manufacture method of known radiator, be to mold a pedestal and a plurality of fin respectively, this pedestal has a plurality of parallel grooves, these a plurality of fins then are plates, and pedestal bestowed the high-temperature heat treatment operation, so that pedestal is softening fully, then these a plurality of fins are placed in softening each groove of pedestal, again the weight of level to uniform pressure is bestowed at the pedestal two ends simultaneously, clamped these a plurality of fins so that these a plurality of grooves are out of shape.Therefore, can reach the purpose that processing procedure is simple, cost reduces.As announce tw Taiwan patent tw569660 number " manufacture method of radiator and structure thereof " patent case January 1 2004 Christian era, promptly disclosing has above-mentioned technology contents.
Though above-mentioned prior art (tw Taiwan patent tw569660 number) can reach the purpose that processing procedure is simple, cost reduces, but in its processing procedure, must carry out weight is bestowed at the pedestal two ends, make the groove distortion and the step of clamping fin, if be applied to highly higher radiator, because the fin apical margin does not have the strong point, therefore fin can produce deflection, make the fin regularity poor, and the depth of parallelism is not good, when especially the fin height is high more, problem is serious more, and then cause heat abstractor in use, and air-flow is unequal, and radiating efficiency reduces.
Summary of the invention
