Method of forming bent heat dissipating unit and apparatus therefor

Abstract

In a method of forming bent heat dissipating unit, the following steps are included: putting a plurality of radiating fins on and around a straight heat pipe to form a heat dissipating unit; engaging the heat dissipating unit with a forming die assembly, so that a plurality of locating die units sequentially arranged on a carrier of the assembly are separately positioned in a space between two adjacent radiating fins; pressing the engaged heat dissipating unit and forming die assembly against a forming block; and driving a processing machine connected to the carrier of the forming die assembly to change the arrangement of the locating die units and thereby bend the heat dissipating unit to a shape corresponding to a profile of the forming block. An apparatus for forming the bent heat dissipating unit through the above steps is also provided.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a method and apparatus for forming bent heat dissipating unit for use on a computer and / or communication related product, and more particularly to a method and apparatus for forming a bent heat pipe with a plurality of radiating fins equally space thereon in an easy and economical manner. BACKGROUND OF THE INVENTION [0002] To enable efficient and effective dissipation of heat transmitted to a heat pipe forming a radiating device, the heat pipe is conventionally divided into three portions, namely, a heat dissipating end, a heat transmitting section, and a heat source connecting end. Normally, the heat pipe is subjected to particular machining to form these three portions. The heat source connecting end is connected to a heat source, so that heat is transmitted from the heat source via the heat source connecting end to the heat transmitting section and the heat dissipating end, at where heat is dissipated using a cooling ...

AI Technical Summary

Benefits of technology

[0006] A primary object of the present invention is to provide a method and apparatus for forming bent heat dissipating unit, with which a plurality of radiating fins could be easily equally spaced on a bent heat pipe.

[0008] A further object of the present invention is to provide a method and apparatus for forming bent heat dissipating unit, which can be easily implemented or operated to shorten the time needed to bend a heat dissipating unit.

[0010] A still further object of the present invention is to provide a method and apparatus for forming bent heat dissipating unit, with which the cost for processing the heat dissipating unit is reduced.

Problems solved by technology

Since the radiating fins 12 must be manually assembled to the curved heat pipe 11 one by one, the curved heat pipe 11 could not be mass-produced and requires very high labor cost.
