Actual temperature.
One kind as above-mentioned technical proposal is improved, and is installed for described mobile device assembling with the outer of its cage connection
Standby, both junctions form thermo-contact, and the external device uses Heat Conduction Material.
Further, described mobile device is smart camera, described external device be hand-held self-shooting bar or head or
Tripod.
As an alternative to the above-described technical solution, described mobile device is intelligent watch.
It is separately below embodiment to a kind of heat accumulation of mobile device proposed by the present invention using smart camera and intelligent watch
Formula temprature control method illustrates.
【Embodiment one】
As shown in figure 1, it is the intelligence for the heat storage type temprature control method for employing a kind of mobile device proposed by the present invention
Camera.
Smart camera in the present embodiment has in a thickness direction by shell 1, display screen 2, battery 3, circuit board 4, core
The stacked structure that piece 5, radome 50, chip 6, radome 60, camera lens 7 form.Its chips 5, chip 6 are main heating
Source, its heat are conducted by radome 50, radome 60 to other Rotating fields respectively.
Due to the specific occupation mode of smart camera, when human hand, which directly holds camera, to be imaged, its working time is not
Can be very long, therefore caloric value is not too large, its surface temperature is normal.But when needing to shoot for a long time, such as when lasting
When shooting more than 45min, the increase of equipment heating amount, the temperature excursion of fuselage, cause human hand extremely uncomfortable when directly holding, and
Because the camera lens of camera is more sensitive to temperature, image quality will be directly affected.
Therefore, the present embodiment uses a kind of heat storage type temprature control method of mobile device proposed by the present invention, is shielding
Phase-change heat-storage material 53 is arranged between cover 50 and battery 3, phase-change heat-storage material is arranged between radome 60 and shell 1
61, phase-change heat-storage material 47 is arranged between circuit board 4 and camera lens 7, phase transformation storage is arranged between circuit board 4 and shell 1
Hot material 41, phase-change heat-storage material 32 is arranged between battery 3 and display screen 2.
It is chip respectively by the order of caloric value from big to small in the stacked structure of smart camera in the present embodiment
5 and chip 6, battery 3, display screen 2, circuit board 4, thus by phase-change heat-storage material decalescence temperature range minimum from
It is phase-change heat-storage material 53 and phase-change heat-storage material 61, phase-change heat-storage material 32, the and of phase-change heat-storage material 47 to arrive small order greatly
Phase-change heat-storage material 41.By choosing appropriate thermal conductivity factor, when camera is just started working either camera power consumption itself simultaneously
When not high, phase-change heat-storage material 32, phase-change heat-storage material 47 and phase-change heat-storage material 41 not decalescence, Heat Conduction Material is only played
Effect.When camera power consumption increases on this basis, either camera usage time increase causes power consumption itself very high, then
Phase-change heat-storage material 53 and phase-change heat-storage material 61, phase-change heat-storage material 32, phase-change heat-storage material 47 and phase-change heat-storage material 41
Decalescence can be started, keep the constant and camera lens temperature of camera surface temperature to disclosure satisfy that requirement.
Therefore, phase-change heat-storage material 53 and phase-change heat-storage material 61, phase-change heat-storage material 32, phase-change heat-storage material 47 are passed through
With phase-change heat-storage material 41, camera can be allowed to keep certain temperature, no more than setting value.
On the other hand, when long-time is shot, if operated completely with hand-held mode, not only arm may feel that labor
Tired, the shake of human hand can also bring influence to shooting quality in itself, therefore using can all use some external for a long time during camera
Equipment manipulates camera.In this case, the radiating mode of camera can also be divided into two using the external device.Specifically such as
In the present embodiment, the hand-held self-shooting bar 8 being connected for camera assembling with its shell 1 is used as external device, and both junctions are formed
Thermo-contact, and the external device uses Heat Conduction Material.When therefore, using hand-held self-shooting bar 8 as external device, it will install outside
A standby part as camera integral heat sink system, area of dissipation is greatly increased, further alleviates the radiating pressure of camera in itself
Power.
【Embodiment two】
As shown in Fig. 2 it is the heat storage type temperature control for employing a kind of mobile device proposed by the present invention
The intelligent watch of method processed.
Intelligent watch in the present embodiment has in a thickness direction by shell 1 ', display screen 2 ', battery 3 ', circuit board
4 ', the stacked structure that chip 5 ', radome 50 ', chip 6 ', radome 60 ' form.Its chips 5 ', chip 6 ' are main
Pyrotoxin, its heat respectively by radome 50 ', radome 60 ' to other Rotating fields conduct.
The present embodiment uses a kind of heat storage type temprature control method of mobile device proposed by the present invention, in radome 50 '
Phase-change heat-storage material 53 ' is arranged between battery 3 ', phase-change heat-storage material is arranged between radome 60 ' and shell 1 '
61 ', phase-change heat-storage material 32 ' is arranged between battery 3 ' and display screen 2 '.
It is chip respectively by the order of caloric value from big to small in the stacked structure of intelligent watch in the present embodiment
5 ' and chip 6 ', battery 3 ', display screen 2 ', circuit board 4 ', thus by phase-change heat-storage material decalescence temperature range most
The order of low value from big to small is phase-change heat-storage material 53 ' and phase-change heat-storage material 61 ', phase-change heat-storage material 32 '.Pass through selection
Appropriate thermal conductivity factor, when when wrist-watch is just started working, either wrist-watch power consumption itself is not high, phase-change heat-storage material 32 ',
Not decalescence, only play Heat Conduction Material.When wrist-watch power consumption increases on this basis, either wrist-watch is used for for a long time
When video calling or LTE calls cause power consumption itself very high, then phase-change heat-storage material 53 ' and phase-change heat-storage material 61 ', phase transformation is stored up
Hot material 32 ' can start decalescence, keep the constant of watch dial temperature, until battery exhausts, watch dial temperature
It can maintain always within setting.
Therefore, wrist-watch can be allowed to protect by phase-change heat-storage material 53 ' and phase-change heat-storage material 61 ', phase-change heat-storage material 32 '
Certain temperature is held, no more than setting value.
For those skilled in the art, other various phases can be obtained according to disclosed structure and principle
The change and deformation answered, and all these change and deformation belongs to protection category of the invention.
