Heat-dissipating fin set in combination with thermal pipe
A heat pipe structure, having a tubular member, a support member and a wick structure. The tubular member is hollow to accommodate the support member and the wick structure therein. The wick structure is located between the tubular member and the support member. The wick structure is supported by the support member to be attached to an interior wall of the tubular member. The material melting point of the wick structure is lower than those of the tubular member and the support member. Therefore, the support member maintains good supporting function during sintering process, such that the wick structure can be adequately attached to interior wall of the tubular member.
The present invention relates to a heat-dissipating fin set in combination with thermal pipe, more particularly to a heat-dissipating fin set in combination with thermal pipe, wherein a heat-conducting material is filled into a gap between a through hole of the heat-dissipating fin set and the thermal pipe.
The conventional heat-dissipating fin set generally comprises thermal pipe with wick structure and working fluid. The working fluid flows through the wick structure and the thermal pipe to have heat exchange with a heat source on the heat-dissipating fin set, thus removing heat from the heat-dissipating fin set.
To solve above-mentioned problem, a heat-conducting material 2a is pasted on outer face of the thermal pipe 20a before the thermal pipe 20a is assembled into the through hole 11a of the fin plate 1a. The heat-conducting material 2a, such as heat-conducting glue or tin paste, will be solidified in the gap to form seamless sealing between the through hole 11a and the thermal pipe 20a.
However, the heat-conducting material 2a may be scratched off by the inner wall of the through hole 11a during the thermal pipe 20a being assembled into the through hole 11a. The scratched heat-conducting material 2a is piled, with uneven thickness, around the through hole 11a on the outmost fin plate 1a. The problem of gap still remains and the provision of the heat-conducting material 2a cannot solve this problem.
Furthermore, the heat-conducting material 2a suffer to the problem of deposit and storage because it should be applied before the assembling of the thermal pipe 20a. Moreover, the heat-conducting material 2a may drop or scatter during paste, which causes dirt and difficulty in processing.
BRIEF SUMMARY OF THE INVENTIONThe present invention is to provide a heat-dissipating fin set in combination with thermal pipe, wherein a heat-conducting material is filled into a gap between a through hole of the heat-dissipating fin set and the thermal pipe to enhance thermal conduction therebetween.
Accordingly, the present invention provides a heat-dissipating fin set in combination with thermal pipe, the heat-dissipating fin set comprising a plurality of fin plates, each of the fin plates having at least one closed through hole, each of the thermal pipe passing through the through hole. Each of the fin plate has an accommodating section atop the through hole and used for accommodating a heat-conducting material. The heat-conducting material is placed into the accommodating section. The heat-conducting material is molten after heating the heat-dissipating fin set and the molten heat-conducting material fills a gap between the through hole and the thermal pipe, whereby a thermal conductance is provided between the through hole and the thermal pipe.
