Description
Technical field
The utility model relates to a kind of heat pipes, specifically, being to be related to a kind of flexible heat pipes, belong to Heat sink technology neck
Domain.
Background technique
Heat pipe is the quick thermal transport property that heat-conduction principle and phase change medium is utilized, through heat pipe by thermal objects
Heat is transmitted to outside heat source rapidly, and the capacity of heat transmission is more than the capacity of heat transmission of any known metal.
Common heat pipe consists of a tube shell, a liquid suction core and an end cover, and will be filled with suitable working solution after the negative pressure being pumped into pipe
Body, make be close to inside pipe wall liquid-sucking core capillary-porous material in it is hydraulically full after sealed.One end of pipe is evaporator section, another
End is condensation segment, is needed to arrange adiabatic section two sections of centres according to application.Liquid in Mao Renxin when one end of the heat pipe is heated
Evacuator body vaporization, steam flow under a slight pressure difference to other end releasing heat and condense into liquid, and liquid is leaned on along porous material again
Evaporator section is flowed back in the effect of capillary force.So circulation not oneself, heat from one end of the heat pipe to the other end, realize heat transfer.
But heat pipe currently on the market, usually rigid pipe, can not arbitrarily change shape, in this way in practice by
Very big limitation has been arrived, it is also very high to the space requirement of electronic component, it is unable to satisfy and some needs being actually subjected to for electronic component
It asks.
Utility model content
It is more flexible, convenient that in view of the above problems, the object of the present invention is to provide a kind of mounting means, effectively avoids
Tube body fractures, and increases the service life of product, and the good heat pipe of heat dissipation performance.
One end of a kind of flexible heat pipes, including closed shell, the shell is evaporator section, and the other end is condensation segment, institute
It states shell inner chamber body and forms evaporation chamber, the middle section of the shell is flexible pipe, and the evaporator section inner wall is along axial equal
Equipped with the first wick layer, the condensation segment inner wall is equipped with copper mesh along the second capillary wick, the flexible inside pipe wall is axially arranged with,
Evaporator section, flexible pipe and the condensation segment is integrally formed.
Further, above-mentioned a kind of flexible heat pipes, the flexible pipe are ripple copper pipe.
Further, above-mentioned a kind of flexible heat pipes, first wick layer be sintered by red copper powder particle and
At powder bed structure.
Further, above-mentioned a kind of flexible heat pipes, second wick layer be sintered by red copper powder particle and
At powder bed structure.
Compared with prior art, technical solution provided by the utility model has following technological merit:
1, technical solution provided by the utility model, one end of shell are evaporator section, and the other end is condensation segment, in shell
Between be partially flexible pipe so that the heat pipe can carry out random complications according to the mounting arrangement of electronic component, mounting means becomes
It is more flexible, convenient to obtain, and has widened the applicable situation of heat pipe, has effectively prevented tube body of heat pipe and fracture, has increased the service life of product.
2, technical solution provided by the utility model is equipped with copper mesh in flexible inside pipe wall, so that liquid refrigerant evaporation interface increases
Greatly, accelerated heat exchanges, and improves the heat dissipation performance of heat pipe, reduces reflux resistance.
Detailed description of the invention
The flexible heat pipes structural schematic diagram that Fig. 1 embodiment 1 provides；
Fig. 2 is axial sectional view in Fig. 1；
Symbology element and its similar component are as follows in figure:
Closed shell 1, evaporator section 2, condensation segment 3, flexible pipe 4, the first wick layer 5, the second capillary wick 6, evaporation cavity
Room 7, copper mesh 8.
Specific embodiment
The claim of the utility model is described in further detail in the following with reference to the drawings and specific embodiments.
A kind of flexible heat pipes provided by the utility model, refering to fig. 1 and Fig. 2, including closed shell 1, the shell 1
One end is evaporator section 2, and the other end is condensation segment 3, and 1 inner chamber body of shell forms evaporation chamber 7, the centre of the shell 1
Section is flexible pipe 4, and the flexible pipe 4 is ripple copper pipe.
2 inner wall of evaporator section is equipped with the first wick layer 5 along axial direction, and first wick layer 5 is by red copper
Powder bed structure made of powder particle sintering.
For 3 inner wall of condensation segment along the second capillary wick 6 is axially arranged with, second wick layer 6 is by red copper powder
Powder bed structure made of particle sintering.
4 inner wall of flexible pipe is equipped with copper mesh 6, and the evaporator section 2, flexible pipe 4 and condensation segment 3 are integrally formed, just
In processing.
For the ease of heat transfer, the material of the shell 1 can be selected from copper, and the radial section of shell 1 is circle, or
Ellipse etc..The caliber of shell 1 is 2-100 millimeters, can be from several millimeters to tens depending on 1 length of shell can be actually needed
Rice, shell 1 with a thickness of 0.1-1 millimeters.
Due to the evaporator section 2 in heat pipe, the working fluid of liquid-sucking core 4 is taken away heat by thermal evaporation, which is work
The evaporation latent heat of fluid, steam flow to the condensation segment 3 of heat pipe from central passage, liquid are condensed into, while releasing latent heat, in capillary
Under the action of power, liquid reflux to evaporator section 2.In this way, just complete a closed circulation, thus by a large amount of heat from heating
Section passes to radiating segment.
Due to shell 1 middle section be flexible pipe 4 so that the heat pipe can according to the mounting arrangement of electronic component and into
Row is arbitrarily tortuous, and mounting means becomes more flexible, convenient, widened the applicable situation of heat pipe, effectively prevented tube body of heat pipe
It fractures, increases the service life of product.
The above content is combine specific preferred embodiment, further detailed description of the utility model, no
It can assert that the specific implementation of the utility model is only limited to these instructions.Without departing from the concept of the premise utility, also
Several simple deduction or replace can be made, it is determined by the appended claims all to shall be regarded as belonging to the utility model
Scope of patent protection.
