Description
Technical field
The utility model relates to a kind of heat pipe, refers to especially a kind of radially innovative design of the heat pipe structure of revers turn part wire netting that has.
Background technology
Existing heat pipe structure design is upper for reaching better heat conduction efficiency, can import the capillary tissue structure form, though the heat conduction efficiency of heat pipe, along with the difference of heat pipe spatial shape, still exist the breakthrough to be improved of some problem points yet existing capillary structure can gain really.
for satisfying present computer, the compactization designs trend of electronic equipment, heat pipe structure is flat thinning and miniaturization thereupon relatively, but thus, originally therefore the capillary structure that is arranged in the inside heat pipe space will produce some problems, because the capillary structure in existing heat pipe is sayed with regard to the processing procedure face, its dictyosome or dictyosome and sintered combined body usually must lean in one plug week side insert again in the heat pipe space and position, in this process, in order to prevent producing changing of the relative positions deviation between dictyosome (or complex) and plug, need mend the neck ring of establishing a rolled in partial section, lean on state in plug with reinforcement dictyosome (or complex), after this dictyosome (or complex) is sintered in the heat pipe space, again plug is taken out, yet, the existing Heat Pipe Capillary Organization Structure of this kind finds in practical application experience, still there are the problems such as the slow and fraction defective of the operating efficiency insert heat pipe is high on its processing procedure, in addition, if its capillary structure is one-sided when form is set, plug also easily has off normal just not affect the problem of capillary structure centre of location degree in inserting the heat pipe steric course.
Another aspect that the utility model institute wish is inquired into is the problem of relevant heat tube capillary structure conductive performance; In general, existing heat tube capillary structure generally is divided into groove form, metal dictyosome, metallic fiber type of weave, sinter from metal powder etc., these capillary structures the distribution characteristic is set, be generally from the heat pipe evaporator section and extend to condensation segment and the axial complete form that is distributed in heat pipe inner wall; Wherein, the heat pipe of the forms such as groove, metal dictyosome, metallic fiber braiding has the characteristic that the capillary resistance is little, the working fluid flow is large, but when being applied to the evaporator section position higher than the use state of condensation segment, because of the capillary force of its capillary structure Action of Gravity Field less than working fluid, make working fluid can't be back to evaporator section, cause heat pipe generation dry combustion method (Dry Out) phenomenon and lost efficacy; It is the heat pipe of sinter from metal powder as for capillary structure, also large characteristic of and capillary resistance large because of the working fluid capillary force, making it possess evaporator section can be higher than the antigravity advantage of condensation segment, but, because the flow resistance of working fluid in the formed cellular capillary structure of metal sintering powder is larger, thereby cause the also shortcoming little than the heat pipe of other capillary structure of its maximum heat biography amount (Qmax).
Therefore, for the existing problem of above-mentioned existing heat pipe, how to develop a kind of innovative structure that can have more desirable practicality, real think again target and the direction of breakthrough for remaining relevant industry.
In view of this, this is engaged in manufacturing development and the design experiences of Related product in for many years the inventor, for above-mentioned target, in detail after design and scrupulous assessment, eventually the utility model of a true tool practicality.
Summary of the invention
The utility model provides a kind of radially heat pipe of revers turn part wire netting that has, and it is that target is thought the innovation breakthrough mainly for how developing a kind of new-type heat pipe structure that has more desirable practicality.
For achieving the above object, the technical solution adopted in the utility model is: a kind of have a radially heat pipe of revers turn part wire netting, comprising:
One body, for having the hollow closed body form of two involution ends, it is distinguished into evaporator section and condensation segment according to thermolysis, and this body inner space is for vacuumizing state and being equipped with working solution again;
At least one wire netting, be located in the evaporator section at least of this body, this wire netting is that the planar dictyosome form of extension that the staggered unit metal line of track and column braiding consists of defines and is formed with a first end and one second end, and this first end, one of them person of the second end are the form that extends to the body condensation segment;
Radially revers turn part, be formed between the first end and the second end of this wire netting, and by this radially formation of revers turn part, make wire netting integral body be a U-shaped aspect, and to consist of this first end and the second end be to be arranged spaced and towards the form of equidirectional extension.
Related content in technique scheme is explained as follows:
1. in such scheme, the first end of described wire netting is forms isometric or that length difference is different from the second end development length.
2. in such scheme, the first end of described wire netting, the second end wherein one or both end phase Lin Chu more are combined with the first sinter from metal powder.
3. in such scheme, described wire netting is two groups and is mutually cross to interconnected form.
4. in such scheme, be combined with the second sinter from metal powder because further inserting in the formed clearance space of arranged spaced between the first end of described wire netting and the second end.
5. in such scheme, described wire netting is that individual layer or plural layer arrange form.
Operation principle of the present utility model and advantage are as follows:
1, the utility model is a kind of has the radially heat pipe of revers turn part wire netting, be mainly by this radially the formation of revers turn part make the innovation structure design of wire netting overall U-shaped aspect, make the utility model structure against existing technologies, due to described radially revers turn part can be directly as wire netting by a limiting section in plug ingress pipe body process, therefore need not be equipped with again other auxiliary positioning member, and wire netting is imported the situation of the skew that can not shake easily in the body process, and wire netting can be stablized and import fast body, and this tool radially the wire netting of revers turn part can spacing plug in the center line of body, if therefore follow-uply can be uniformly distributed on the symmetrical internal face of body when inserting metal dust, therefore technical characterictic of the present utility model can reach and reduce the heat pipe manufacturing cost, significantly promotes and wire netting (being capillary structure) is inserted the operating efficiency of heat pipe and reduce its fraction defective and improve the practical improvement such as wire netting centre of location degree and better industry is utilized benefit.
