For example, in this illustrative embodiment, as Figure 1-Figure 2, balloon segment includes the first balloon segment 41, second
Balloon segment 42, third balloon segment 43 and four gasbags section 44, the rectangular shape of four balloon segments, are located at four of mobile phone 1
Angle.Radiating segment 3 includes the first radiating segment 31, the second radiating segment 32, third radiating segment 33, the 4th radiating segment 34, the 5th radiating segment
35, the 6th radiating segment 36 and the 7th radiating segment 37.First three radiating segment is layed in three main heat sink points of mobile phone, and latter four dissipate
Hot arc is set around mobile phone edge.Wherein, 31 caliber of the first radiating segment is thinner, is layed on 1 mainboard of mobile phone along S type serpentine track
Side, the second radiating segment 32 are also layed in 1 battery of mobile phone, 8 surface along S type serpentine track, and third radiating segment 33 is that a diameter is thicker
Straight tube is located at below 1 socket of mobile phone.The connection relationship of seven radiating segments and four balloon segments is followed successively by, and third radiating segment 33 connects
It is connected between the first balloon segment 41 and the second balloon segment 42；5th radiating segment 35 is connected to the second balloon segment 42 and third balloon segment
Between 43, the 6th radiating segment 36 is connected between third balloon segment 43 and four gasbags section 44, and the 7th radiating segment 37 is connected to
Between four gasbags section 44 and the first radiating segment 31, the first radiating segment 31, the second radiating segment 32 and the 4th radiating segment 34 are sequentially connected in series
Between four gasbags section 44 and the first balloon segment 41, seven radiating segments and four balloon segments connect to form a closed circulation
Pipeline 2.The air pressure in all changeable circulation line 2 of any one balloon segment 4 is pressed, and then pushes fluid flowing, accelerates heat dissipation.
As shown in Fig. 2, 34 to the 7th radiating segment 37 of the 4th radiating segment is arranged along mobile phone outer ring, the length of circulation line 2 can be extended as far as possible,
The volume for increasing heat exchange medium, to improve heat dissipation effect.
For convenience, in present embodiment the division of radiating segment be depending on the main distributed areas of radiating segment,
The division of radiating segment can also have other forms, it will be understood by those skilled in the art that division mode has no effect on its structure spy
Point.In addition, the number of radiating segment 3 and balloon segment 4 can also be other quantity, setting specifically can according to need, such as hair
The a fairly large number of terminal device of hot spot, can arrange more radiating segments, for larger-sized equipment, settable more air bags
Section.The paving mode of radiating segment may be other shapes, and details are not described herein again.
In this illustrative embodiments, as shown in figure 3,33 left end of third radiating segment connection the below 1 socket of mobile phone
One balloon segment 41, right end connect the second balloon segment 42, and 41 left end of the first balloon segment connects the 4th radiating segment 34, the second balloon segment 42
Right end connects the 5th radiating segment 35.With in scheming from left to right for fluid flow direction, in the exit (first of the 4th radiating segment 34
The inlet of balloon segment 41) one check valve 5 of installation, pacify in the exit (inlet of the second balloon segment 42) of third radiating segment 33
Another check valve 5 is filled, the conducting direction of two check valves 5 is consistent with fluid flow direction.Fluid include the first component, first
The boiling point of component be m, 40 DEG C≤m≤100 DEG C.The setting of two check valves 5 make third radiating segment 33 and the first balloon segment 41 it
Between form the space of relative closure, when temperature reaches the boiling point of the first component at socket, first group of branch's boiling vaporization, from
And bulk gas is generated, change the air pressure in enclosure space, and then push the liquid in third radiating segment 33 according to 5 institute of check valve
The direction of restriction is flowed, and drives the flowing heat dissipation of the fluid in entire circulation line 2 with this.At socket temperature close to not yet
When reaching boiling point, also due to the rapid evaporation vaporization of fluid changes air pressure, and then fluid flowing is pushed, can also play and drive stream
The effect of body active cycle.Therefore, which can also press driving fluid together with balloon segment and actively flow in circulation line 2
It is dynamic, certainly in no pressing balloon segment, fluid active cycle can also be realized by this way, push phase interworking with balloon segment
It closes, achievees the purpose that improve radiating efficiency.In other embodiments, two check valves 5 also be can be set in other positions, such as all
The exit of two balloon segments is set, be perhaps separately positioned on third radiating segment 33 inlet and exit or respectively
The inlet of first balloon segment 41 and the exit of the second balloon segment 42 are set, third radiating segment 33 can also be positioned only at
Part pipeline both ends, etc. make the gas of vaporization be enough to push away as long as can form the space of relative closure between two check valves 5
Dynamic fluid flow inside.
The boiling point of first component can need to select according to the temperature and heat dissipation of interior of mobile phone heat radiation point, such as can be second
Alcohol, acetone, ethyl acetate etc..For example, component boiling point m meets 40 DEG C≤m≤100 DEG C, if boiling temperature is too low, such as less than 40
DEG C, device can all operate normally in mobile phone 1, heat dissipation needs are had no, and the first component is boiled vaporization too early, until temperature raising need
The effect that auxiliary improves radiating efficiency is not had when radiating；If boiling temperature is excessively high, such as higher than 100 DEG C, then fluid is always
It is difficult to vaporize, loses the effect of auxiliary heat dissipation.Therefore, it is necessary to need to select according to the temperature and heat dissipation of interior of mobile phone heat radiation point
Suitable component.First component absorbs heat vaporization at heat radiation point, and when hand built-in temperature reduces, the first component of vaporization can
It is changed into liquid again, returns to and go to recycle in fluid.Heat exchange medium can contain only the first component, can also be in addition to first
Component also includes other components, such as water etc., the disclosure is not to this progress particular determination.
It will be understood by those skilled in the art that similar structure similarly can also be set in other radiating segments 3, for example,
The part pipeline two sides of first radiating segment 31 or the second radiating segment 32 are installed by check valve 5, the common vapour of the first component of multistage pipeline
To change driving fluid flowing, can be further improved fluid-flow rate, accelerates heat dissipation, i.e. the quantity of check valve 5 can be multiple, as long as
The conducting direction of each check valve 5 is consistent with heat exchange medium flow direction, recycle heat exchange medium can along circulation line.
Certainly, in other embodiments, when circulation line is shorter, the first component is formed by enclosure space in entire circulation line
When can push internal heat exchange fluid flowing by vaporization, a check valve can also be only arranged in entire circulation line, it is ensured that
Heat-exchange fluid and the first component of vaporization recycle in one direction.
In this illustrative embodiments, as shown in figure 4, two check valves 5 include valve casing 51, block piece 52 and valve
Core, is series at circulation line 2, and in present embodiment, valve core structure is sphere 53.Wherein, left side valve casing 51 is connected to the 4th and dissipates

513 direction of liquid mouth is gradually increased.Block piece 52 is set to liquid outlet 513, has the through-hole flowed through for heat exchange medium.Sphere 53 is set
In in valve chamber 511, be located in the liquid inlet between 512 and block piece 52, and can be moved in valve chamber 511, thus inlet 512 and go out
It needs to guarantee that certain space supplied gas is mobile between liquid mouth 513.53 diameter of sphere is greater than 512 bore of inlet and is less than liquid outlet
513 bores.When fluid is flowed into from the inlet 512 of valve casing 51, sphere 53 is pushed to move to liquid outlet 513, due in valve chamber
In the radial direction, the maximum cross-section area of sphere 53 is greater than the area of section of inlet 512, so sphere 53 is blocked the resistance of part 52
Gear, and fluid flows out liquid outlet from the through-hole of block piece 52.If fluid reversely flows into valve chamber 511 by liquid outlet 513, sphere is pushed
53 move to inlet 512, and since 53 diameter of sphere is greater than inlet diameter, then can block inlet 512 leads to inlet
Closing, and flow out fluid can not from inlet 512, therefore form the principle of control one-directional fluid flow.Sphere 53 can be adopted
With materials such as steel or rubber, certainly, in other embodiments, spool can also be using structures such as other structures, such as cylinder, only
It wants spool to be greater than inlet area of section along the maximum cross-section area of valve chamber radial direction and is less than liquid outlet area of section, fluid is reversed
When flowing, spool can block inlet, and the effect of control fluid flow direction can be realized.Block piece 52 can be using materials such as steel
Matter, structure can be the structures such as netted, palisade.5 structure of check valve is simple, and cost is relatively low, can be realized in small pipeline
Fluid traffic organising.
In this illustrative embodiments, as shown in figure 4, left side valve casing 51 can be structure as a whole with the 4th radiating segment 34,
Similarly, right side valve casing 51 can be structure as a whole with third radiating segment 33.It is i.e. direct when processing radiating segment 3 with the material of radiating segment
It is integrally formed out the valve casing structure being gradually flared, thus can simplify 5 structure of check valve, is not necessarily to separately formed valve casing 51, and simplify
The mounting means of check valve 5.51 exit of valve casing in the present embodiment can directly with the first balloon segment 41 or the second balloon segment
42 connections, in other embodiments, if check valve 5 is located at the other positions of circulation line 2, can also similarly pass through integrated molding
