The structure of 5th embodiment of dynamic terminal is similar to the structure of first embodiment, the difference is that: dissipating in the 5th embodiment
Hot material is different from the heat sink material in first embodiment.In the 5th embodiment, heat sink material 644 is by heat absorption heat accumulating
6442 and the mixing composition of heat conduction and heat radiation material 6444, the heat conduction and heat radiation material 6444 is for giving the heat transfer on cabinet 64
The heat absorption heat accumulating 6442, the heat absorption heat accumulating 6442 are used to absorb and store the conduction of heating element generation extremely
Heat on the cabinet 64, and store the heat that the heat conduction and heat radiation material 6444 is conducted.
Heat absorption heat accumulating 6442 and the mass ratio of heat conduction and heat radiation material 6444 are 1:1.The heat absorption heat accumulating 6442
Heat absorption and heat accumulation can be carried out, therefore, conduction can be absorbed to the heat on cabinet 642 and be stored in heat absorption heat accumulation material
In material 6442, to reduce the temperature of heating element 42, and shell can be directly delivered to avoid heat by storing heat
20；The heat conduction and heat radiation material 6444 can be conducted heat and be radiated, and therefore, can be accelerated to heat absorption heat accumulating 6442 to case
The absorption of heat on body 642, after heat absorption heat accumulating 6442 is absorbed into sufficient heat, and can be to heat absorption heat accumulating
Heat in 6442 radiates, and further enhances the cooling effect to heating element 42.
Heat absorption heat accumulating 6442 is by having the material of heat absorption and heat storage function to be made.Heat absorption heat accumulating 6442 is used for
Absorb the heat on cabinet 642 and by the heat storage of absorption in heat absorption heat accumulating 6442.Utilize heat absorption heat accumulating
6442 can distribute by heat absorption and after heat accumulation to certain temperature into air, avoid the heat of heating element 42 straight
It connects and is transmitted on shell 20.
In the present embodiment, heat sink material 644 can be a kind of phase-change material, can change object with temperature change
Rationality matter simultaneously can absorb a large amount of heat, and with the increase of the heat of absorption, it is another that heat sink material 644 is gradated from a kind of phase
A kind of phase can stablize another phase of maintenance after absorbing sufficient heat and no longer absorb heat, and when heating element 42 does not generate
When heat or the lower heat of generation, heat sink material 644 can be carried out heat dissipation and gradually with the reduction of heat by another phase by
Gradually revert to original phase.Wherein, heat sink material 644 can with the variation of temperature from solid phase to liquid phase or liquid phase to solid phase
Perhaps liquid phase changes to solid phase or liquid phase is to gas phase or gas phase to liquid phase to gas phase for transformation or solid phase.
In the present embodiment, heat sink material 644 preferably comprises the silica and polyethylene glycol that mass ratio is 1:1~1:9.
Specifically, the phase transition temperature that the heat sink material 644 is mixed to prepare is 40 degree, i.e., after the heat of cabinet 642 reaches 40 degree, heat dissipation
Material 644 carries out decalescence, and the heat of conduction to cabinet 642 that heating element 42 generates is taken away, to first device that generates heat
Part 42 cools down.
In other embodiments, heat sink material 644 can also be inorganic phase-changing material or composite phase-change material etc..
In the present embodiment, heat sink material 644 by it is several using silica as cyst wall, using polyethylene glycol as the micro-capsule of capsule-core
It constitutes.The heat sink material 644 of the microcapsule structure preferably can carry out heat absorption heat accumulation to heating element 42, and then reach good
Heat dissipation performance.
Specifically, polyethylene glycol is added in certain density silica solution, after all dissolutions, CaCl2 is added dropwise and promotees to coagulate
Agent solution, so that sol gel reaction occurs in silica solution for polyethylene glycol, forms three dimensional network after standing under strong stirring
Network structural gel；By gel in 80 DEG C of baking ovens 24~48h of forced air drying, be cooled to room temperature, can access with organosilicon oxygen
Compound generate under alkaline condition it is a large amount of using silica dioxide gel as cyst wall, using emulsify after polyethylene glycol as the micro- of capsule-core
Capsule.I.e. in each micro-capsule, silica wraps the polyethylene glycol as capsule-core as cyst wall, so that polyethylene glycol is from admittedly
It will not be leaked during phase-liquid phase, can be good at being lived by Silica-coated.The heat dissipation material of the formation microcapsule structure
Material 644 when the temperature that heating element 42 is conducted to the heat of the cabinet 642 reaches 40 degree, open by the heat sink material 644
Begin to absorb the heat on cabinet 642, and capsule-core gradually increasing gradually from solid-liquid with heat itself, when capsule-core all
After being converted into liquid phase, the heat that heat sink material 644 absorbs has been saturated, and stops absorbing heat, and outside heating element 42
After the temperature in portion is gradually decrease to preset temperature, capsule-core comes out the heat of absorption, is transmitted in air, and capsule-core meeting
Gradually decreasing and be gradually converted to solid phase from liquid phase with its body heat is converted by the circulation of above-mentioned solid phase to liquid phase, from
And heating element 42 cools down, and improves the heat dissipation performance and reliability of mobile terminal.
In other embodiments, heat sink material 644 can also be other structures, enable heat sink material 644 by from
The circulation conversion for being solid to gas phase to cool down to heating element 42.
Heat conduction and heat radiation material 6444 can be the preferable materials of heat dissipation performances such as graphite or metal.Wherein, heat conduction and heat radiation
Material 6444 is preferably graphite, and quality is softer to be easily worked.
The manufacturing process of heat sink material 644 are as follows: heat radiator material 6442 is smashed to pieces and strong stirring obtains powder, due to
The diameter of powder is far longer than the diameter of each micro-capsule, therefore will not destroy the microcapsule structure in heat radiator material 6442；Again
Powdered heat conduction and heat radiation material 6444 will be smashed into pieces and powdered heat radiator material 6442 is mixed to form heat sink material
644, so that heat sink material 644 has the function of heat absorption, heat accumulation and heat dissipation.
It is the embodiment of the embodiment of the present invention above, it is noted that those skilled in the art are come
It says, without departing from the principles of the embodiments of the present invention, several improvements and modifications can also be made, these improvements and modifications
It is considered as protection scope of the present invention.
