The heat dissipation technology of efficiency.
Background technology
By the electronically or mechanically element or component of current known many, heat can be all generated in its operation process, in order to keep away
Exempting from them reduces its efficiency because of heat in operation process or causes damage, can all be installed additional in manufacture or design radiator or
Heat transfer is first dissipated by radiator or heat dissipation element from electronic component or mechanical organ, recycles circulation by heat dissipation element
Fluid does heat exchange and removes the heat that electronic component or mechanical organ are given birth to from working environment, and then reaches cooling to improve
The working efficiency of element and the purpose for avoiding damage.The radiator for being most commonly used for electronic component at present is a kind of aluminium extruded type heat dissipation

Volume (total volume that ontology 50 lengthens raised line 51 is enough), must be molded with squeezing type processing technology, thus will produce aftermentioned
Many missings:1. parallel 51 radiator structure of long raised line of strip can only be molded, it can not be molded various different shapes, example according to need
Such as densely covered boss column, or the raised line etc. of difference is radiated, thus have the insufficient missing of applicability;2. crowded type rapidoprint is limited to
Soft metal, mainly aluminium just can not be applicable in, therefore have material selection some quality harder metal or alloy
Limited missing;3. after crowded type machine-shaping, flash will produce, it is necessary to do the processing of burr removing, thus have increase processing cost
Missing;4. 50 one side of radiator body is burnishing surface 52, the effect of no air heat transfer closely connected with element by heat-conducting glue,
Only radiating by the surface of long raised line 51, heat dissipation is not evident, thus known product must do volume greatly to improve heat dissipation,
And cost is not only significantly increased greatly in volume, but also electronic product now is gradually particular about in the requirement of minification, it is real to have
The missing of demand is not met.
Furthermore novel No. M292731 " radiator structure " of TaiWan, China, is to be located at cooling base with netted radiating fin
On, although can be by increasing heat dissipation area by improving radiating effect, however, netted radiating fin is not the plane with cooling base
It is parallel, also it is non-between each netted radiating fin be arranged in a manner of spaced, but it is interconnected with special angle, with
Cause, which has volume big, occupied space and application range and the missings such as is restricted, to be generated.
Novel No. M352636 " radiator " of TaiWan, China, is to be located at LED light-emitting component with netted radiator
Front, although netted radiator other than it can conduct the thermal energy of LED light-emitting component, and can allow light source to be worn by mesh-like area
It is shot out, however, how much mesh-like area can still stop the penetrance of light source, so that the luminous efficacy of LED light-emitting component is influenced, this
Outside, netted radiator is single piece construction, and heat dissipation area is still insufficient, to influence whole heat dissipation.

Extrude miniature concaveconvex structure, then by stamping technology formed concaveconvex structure radiating fin, recycle radiating fin with
The combination of substrate, to obtain required radiator.Although the patent has the heat dissipation effect of heat conduction, but its metallic plate is to belong to thin
The structural form of piece, so that the specific surface area of heat dissipation can be influenced because of volume deficiency;In addition, made of the patent punch process
The process that radiator must do Burr removal, so that increasing the complexity of manufacturing process;Moreover, on the patent radiating fin
Protrusion volume and recess portion volume between error rate be more than 10%, and the error rate between protrusion outer diameter and recess inner diameter is more than
10%;That is, the volume of protrusion is more than the volume about 10% or more of recess portion, the outer diameter of protrusion be more than the internal diameter about 10% of recess portion with
On;Compared to the volume that the volume of each protrusion of the present invention is no better than each recess portion, the outer diameter of each protrusion is no better than each recess portion
Internal diameter, so the two has apparent technological disparity.Certainly, No. 310298 patents of invention of I can be due to volume too small factor
The specific surface area for limiting heat dissipation, to influence whole radiating efficiency.
Edge is, although the technical characteristic for being shaped to radiating fin with stamping technology has been disclosed for;However, so far
Until, it is not yet found that closing radiator of the protrusion volume no better than recess portion volume and protrusion outer diameter no better than recess inner diameter
Patent or paper are suggested, and therefore, creator of the present invention actively makes great efforts to study, and through developing with great concentration, develops a kind of practicality finally
And the present invention that effect is more promoted.
