Description
Technical field
The utility model relates to a kind of heat pipes, concretely relate to a kind of heat pipe of different tube diameters.
Background technique
At this stage, heat pipe is because it has the advantages that the electricity for being widely used in having larger calorific value compared with high heat transfer amount
In subcomponent.When the heat pipe works, fever electronics is absorbed in fire end using the low boiling point working media of tubular body filling
Carburation by evaporation after the heat that element generates, steam moves to radiating end with heat, and releases heat in radiating end liquefaction condensation
It runs out, to radiate to electronic component.Working media after the liquefaction is under the action of capillary structure of inner wall of heat pipe
It is back to evaporation part, continues carburation by evaporation and liquefaction condensation, makes working media in heat pipe internal circulation movement, by electronic component
The heat of generation endlessly distributes.The movement of general driving working media depends on: amount of thermal conduction, capillary
Pipe pressure, in capillary for driving the resistance transmitance of the flow direction of working fluid.
In order to improve the heat conduction efficiency of heat pipe, the method that compound capillary structure would generally be used in the prior art, respectively
The advantage and disadvantage of the different capillary structure of kind are as follows:
The capillary pressure for being sintered powder capillary is big, therefore brilliant for the working fluid conveying capacity of gravitation resistance, root
According to the clip effect of porous sintered powder, thermal conductivity is good, due to the gradual generation of boiling limitation, does not generate temperature rapidly
Rise phenomenon.But since transmitance is small, pressure loss when driving working fluid is mobile is big.
The transmitance of groove capillary is big, and the pressure loss is small when driving working fluid is mobile.Especially, simple groove capillary
When pipe makes thermal conductivity tube wall, it can be integrally formed, it is advantageous in price.But the diameter of capillary is big, capillary pressure is small,
In the overheat drying regime of part, driving capability is in a disadvantageous position, and due to the rapidly generation of boiling limitation, the temperature generated rapidly rises
Phenomenon.
Although microfibre capillary capillary pressure is big, resistance to heat is also beaten；Transmitance is small and drives working fluid mobile
When the pressure loss it is big, part overheat drying regime in driving capability be in a disadvantageous position.
The capillary pressure of shield capillary is intermediate degree, and transmitance is small and the pressure loss is big when driving working fluid, heat
Resistance is also big.
There are some merits and demerits in above-mentioned single capillary structure, in order to enable the state optimization of capillary, existing
Having also has many capillary pipe structures for using MULTIPLE COMPOSITE capillary in technology, improve capillary pressure and transmitance.However, this kind of
Heat pipe with two or more capillary type and structure, manufacturing process is relative complex, cost of manufacture is also relatively high.
Summary of the invention
In view of the deficiencies of the prior art, the utility model proposes a kind of heat pipes with different tube diameters, not using it
Same inside and outside diameter optimizes heat conduction efficiency so that the tube body of different piece has different capillary pressure and transmitance.
The utility model technical scheme applied to solve the technical problem is: a kind of heat pipe of different tube diameters, including one
The hollow tube of both ends sealing, is injected with working media in the hollow tube；The heat pipe is divided into first segment tube body and
Two sections of tube bodies, the first segment tube body and second segment tube body have different outer diameter and inner diameters, the first segment tube body and the
Capillary structure is equipped on the inner wall of two sections of tube bodies, the first segment tube body is identical with the capillary structure of second segment tube body.
Further, the length ratio of the first segment tube body and second segment tube body is 1:5~1:1.
Further, the outer diameter ratio of the first segment tube body and second segment tube body is 1:3~1:1.1.
Further, the capillary structure of the first segment and second segment is formed by metal powder sintered.
The beneficial effects of the utility model are: compared with prior art, the heat pipe of the offer of the utility model by two
There is section the tube body of different tube diameters to form, and the capillary structure of two sections of tube bodies is identical；Working fluid in heat pipe bringing-up section by
After hot vapour, radiating segment is flowed to, in radiating segment tube wall condensation liquefaction, the working fluid after liquefaction returns under the action of capillary force
It flow to bringing-up section；In the utility model, using the lesser one end of caliber as bringing-up section, since the caliber of bringing-up section is smaller,
Its capillary force is larger, flows back more apparent, substantially increases the heat conduction efficiency of heat pipe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of heat pipe provided by the invention.
Wherein, 1- first segment tube body；2- second segment tube body；3- capillary structure.
Specific embodiment
The utility model is further illustrated below by specific embodiment.But it is practical new that these examples are merely to illustrate this
Type rather than limitation the scope of the utility model.
As shown in Figure 1, a kind of heat pipe of different tube diameters, the hollow tube including both ends sealing, the hollow tube
Inside it is injected with working media；The heat pipe is divided into first segment tube body and second segment tube body, the first segment tube body and second
Duan Guanti has different outer diameter and inner diameters, is equipped with capillary structure on the inner wall of the first segment tube body and second segment tube body,
The capillary structure of the first segment tube body and second segment tube body is formed by metal powder sintered.The first segment tube body and second
The length ratio of Duan Guanti is 1:5~1:1.The outer diameter ratio of the first segment tube body and second segment tube body is 1:3~1:1.1.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck
The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and
Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered
It is defined by the claims.
