Description

The radiating module of tool loop type heat pipe

Technical field

The present invention relates to a kind of radiating module, particularly relate to a kind of innovation radiating module structure having loop type heat pipe.

Background technology

On general existing common radiating module structure form Design, it is common that be made up of radiating seat, fin and heat pipe, To utilize this radiating seat to absorb heat, and conduct heat to fin by heat pipe and dispel the heat.

But existing radiating module structure form described in leading portion finds that in broad practice experience still there are some asks Topic and scarce fraud；For example, the heat pipe that existing radiating module is used, it is common that be set as straight tube or U-tube shape so that it is cooling tube Section wears group in the default site of perforation of fin, but, because this kind of its internal working solution phase transformation displacement path of heat pipe is one The state of coming and going, consequently, it is possible to cause between its boil-off gas with condensed fluid the state being to carry out a past relative conflict, thus causes The heat conduction efficiency of its heat pipe is greatly affected, radiating effect cannot promote further.

Therefore, for the problem existing for above-mentioned existing radiating module structure, how to develop the more preferable practicality of one Innovation structure, the dealer that is actually correlated with must make great efforts again research and development break through target and direction.

In view of this, inventor this in being engaged in manufacturing development and the design experiences of Related product for many years, for above-mentioned target, Design in detail and after scrupulous assessment, obtain true this creation having practicality eventually.

Summary of the invention

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment the invention will be further described:

Embodiment: refer to shown in Fig. 1 ~ 4, has a preferred embodiment of the radiating module of loop type heat pipe for the present invention, only these Embodiment is intended for purposes of discussion, is not limited by this structure in patent application.

Described radiating module A includes following composition: a radiating seat 10, sets face 11 and a radiating surface including a pyrotoxin group 12；At least two fins 20, are mounted on radiating surface 12 correspondence position of radiating seat 10 in configuration location, interval form, each fin 20 it Between be formed with heat radiation gap 21, and fin 20 includes installing limit 22 and an extension edge 23；At least primary Ioops type heat pipe 30, Set the periphery being positioned at fin 20 in ring form group, loop type heat pipe 30 is internal as shown in Figure 4, has in vacuum sealing state Primary Ioops type runner 31, this loop type runner 31 is provided with working solution 32 and a capillary structure 33, this loop type heat pipe 30 The installing limit 22 of corresponding fin 20 is provided with one first overlap joint tube side 301, the extension edge 23 of the corresponding fin 20 of this loop type heat pipe 30 Then having one second overlap joint tube side 302, described loop type heat pipe 30 is mounted on heat radiation with its pipeline section being provided with the first overlap joint tube side 301 Seat 10；And wherein, the spacing formed between the first overlap joint tube side 301 to the second overlap joint tube side 302 of loop type heat pipe 30 is (such as figure Shown in the W1 of 5), must constitute more than the spacing (as shown in the W2 of Fig. 5) formed between installing limit 22 to the extension edge 23 of fin 20 Loop type heat pipe 30 groups setting is positioned at fin 20 periphery and presents angle of inclination state (as a shown in Figure 6)；Wherein, fin 20 Installing limit 22 and extension edge 23 are arranged with at least one overlap joint concave edge 24, with respectively for the first overlap joint tube side of loop type heat pipe 30 301 and second overlap joint tube side 302 overlap and embedding assemble conjunction.

By said structure composition design, radiating module A of the present invention mainly provide one have loop type heat pipe 30 in Loop shaped group sets the configuration not seen before being positioned at fin 20 periphery form, for considering that it reaches the reasonable of assembled state Property, must make wherein loop type heat pipe 30 first overlap joint tube side 301 to the second overlap joint tube side 302 between formed spacing (as Shown in the W1 of Fig. 5) more than the spacing (as shown in the W2 of Fig. 5) formed between installing limit 22 to the extension edge 23 of fin 20, whereby Allow loop type heat pipe 30 be able in loose fit state set to the periphery of (as shown in the arrow L1 of Fig. 5) fin 20, then make loop The inclined angle state of type heat pipe 30 (as shown in the arrow L2 of Fig. 6) is connivent in fin 20 periphery to take group；The present invention is dispelled the heat mould In block A running, the pyrotoxin group that a pyrotoxin (figure does not illustrates) is mounted on radiating seat 10 is set face 11, when radiating seat 10 absorbs heat After, loop type heat pipe 30 can be conducted heat to by radiating surface 12 and be provided with pipeline section and the fin 20 of the first overlap joint tube side 301, return Working solution 32 within road type heat pipe 30 is understood carburation by evaporation after being heated and fast for heat speed belt is caused the second overlap joint tube side 302 and reaches scattered The hot state of cooling, the working solution 32 then cooling down condensation can guide back the first overlap joint tube side 301 again by capillary structure 33, be formed One loop-type, heat radiation recurrent state that smooth degree is splendid, and simultaneously with the first overlap joint tube side of this loop type heat pipe 30 301, the interval configuration fin 22 of the second overlap joint tube side 302 overlap joint combination, is able to by between its wide area of dissipation expanded and heat radiation Gap 21, subsidiary loop type heat pipe 30 reaches excellent heat sinking benefit.
