Abstract
A heat radiating fin structure is composed of a hollow copper tube, several heat radiating fins made of aluminum and with through hole for fixing them to the hollow copper tube, and a heat conducting tube sleeved by said hollow copper tube. Its manufacture is also disclosed.
Description
Technical field
The present invention relates to a kind of shaping method of radiator fin and structure, refer in particular to aluminum shaping method of radiator fin and the structure of a kind of use on the heat pipe radiator.
Background technology
The heat pipe radiating appliance of existing tool high cooling efficiency has the hollow heat-conducting plate that is sticked mutually with CPU, in heat-conducting plate, be provided with the vertical heat pipe that is the U type, upside at heat-conducting plate is provided with radiating fin, and this vertical heat pipe runs through radiating fin and fixed.
In the hollow heat-conducting plate, be filled with hydraulic fluid, this hydraulic fluid promptly can be transformed into gas behind the heat of electronic components such as heat-conducting plate absorption CPU, this hot gas can move to an end place of radiating fin along with the vertical heat pipe that is communicated with heat-conducting plate, the heat that conducts high-temperature gas by the heat of radiating fin leaves, the High Temperature Gas behind the heat of leaving is known from experience the hydraulic fluid that reverts back to liquid state and is back in the hollow heat-conducting plate again, so that carry out heat radiator circulation next time, by the circulation of this gas-liquid phase transitionization, reach the excellent radiating effect of efficient.
Above-mentioned radiating fin is divided into two kinds of copper and aluminum radiating fins, with the copper radiating fin, be on each radiating fin, to stamp out to have the heat supply conduit to run through the perforation of usefulness, and the application of force direction towards punching press around the perforation is extended with the ring edge of fitting, special dies with high price when assembling one by one is assembled in heat pipe in the mode that heat pipe runs through perforation radiating fin, making fits encircles edge and heat pipe applying, place the tin stove to heat heat pipe and radiating fin again, make the tin cream or the tin bar that are arranged on the ring edge inboard of fitting fuse so that radiating fin and heat pipe are fixed.In addition, the cost height of copper sheet, Heavy Weight, and after the heating of tin stove, the copper metal can produce the melanism situation, therefore must carry out purifying and surface-treated reprocessing operation, causes cost to be difficult for falling.
In addition with the aluminum radiating fin, it is to stamp out to have the heat supply conduit to run through the perforation of usefulness on each radiating fin equally, and the application of force direction towards punching press around the perforation is extended with the ring edge of fitting, when assembling, only need manually one by one to be assembled in heat pipe in the mode that heat pipe runs through perforation radiating fin, making fits encircles edge and heat pipe applying, on the aluminum radiating fin, carry out the nickel plating operation again, allow the nickel metal fill up heat pipe and the intermarginal space of ring of fitting, so that radiating fin and heat pipe are fixed.But the nickel plating operation not only can cause environmental pollution, and the cost height, and the aluminum radiating fin surface color after the nickel plating can change, and can't keep the primary colors of aluminum metal, and therefore except that the cost that can't reduce radiating fin, its outward appearance also is not subjected to consumer's favor.
If the aluminum radiating fin does not carry out the nickel plating operation, then radiating fin and heat pipe to engage effect just not good, the situation that is easy to cause the aluminum radiating fin to rock on heat pipe takes place, and significantly has influence on the heat conduction efficiency of aluminum radiating fin and bad in radiating effect.
Summary of the invention
Main purpose of the present invention is to overcome the deficiencies in the prior art and defective, provides a kind of use on the heat pipe radiator, and splendid aluminum shaping method of radiator fin and the structure of fixed effect.
For reaching above-mentioned purpose, the present invention takes following technological means that a kind of shaping method of radiator fin is provided, and it comprises:
Radiating fin number of assembling steps: will stamp out perforation on the aluminum radiating fin, the aluminum radiating fin is set in the hollow copper pipe outside with perforation;
Copper pipe and radiating fin positioning step: among mold rods insertion copper pipe, allow the hollow copper pipe expansion make its outer wall closely to fit with perforation;
Copper pipe and heat pipe number of assembling steps: hollow copper pipe is set in the outside of heat pipe, makes the outer wall of the inwall of hollow copper pipe and the heat pipe location of fitting.
Heat radiation fin structure of the present invention includes the aluminum radiating fin that plural pieces is arranged on the heat pipe outside, this aluminum radiating fin upper punch is pressed with the perforation of tool applying ring edge, wherein, inboard outer wall and the hollow copper pipe of boring a hole and combining of being provided with of perforation, this hollow copper pipe inside then is equipped with heat pipe.
Ductility by the material of above-mentioned hollow copper pipe own, improve the fixed effect of hollow copper pipe and aluminum radiating fin, to be fixed with the hollow copper pipe and the heat pipe fit of aluminum radiating fin again, therefore not having radiating fin rocks and locatees not good situation and take place, and because locating effect is good, therefore do not need to carry out any subsequent process steps,, improve the competitiveness of product in market so can reduce the cost of manufacture of heat pipe radiator.

The specific embodiment
Shaping method of radiator fin of the present invention, it comprises:
The radiating fin number of assembling steps: please referring to Figure 1 and Figure 2, will stamp out on the aluminum radiating fin 10 perforation 11, being formed with the ring edge 12 of fitting around the perforation 11, aluminum radiating fin 10 11 is set in hollow copper pipe 20 outsides to bore a hole;
Copper pipe and radiating fin positioning step:, among mold rods 21 insertion copper pipes 20, allow hollow copper pipe 20 expansions make its outer wall closely to encircle edge 12 applyings with applying please referring to Fig. 3 and shown in Figure 4;
Copper pipe and heat pipe number of assembling steps: cooperate referring to shown in Figure 6, hollow copper pipe 20 is set in the outside of heat pipe 22, make the inwall of hollow copper pipe 20 fit and locate with the outer wall of heat pipe 22.
