Actual temperature.
A kind of improvement as above-mentioned technical proposal installs for the mobile device assembly with the outer of its cage connection
Standby, the junction of the two constitutes thermo-contact, and the external device uses Heat Conduction Material.
Further, the mobile device is smart camera, the external device be hand-held self-shooting bar or holder or
Tripod.
As an alternative to the above-described technical solution, the mobile device is smartwatch.
It is separately below embodiment to a kind of heat accumulation of mobile device proposed by the present invention using smart camera and smartwatch
Formula temprature control method is illustrated.
[embodiment one]
As shown in Figure 1, being to use a kind of intelligence of the heat storage type temprature control method 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, shielding case 50, chip 6, shielding case 60, camera lens 7 form.Wherein chip 5, chip 6 are main fever
Source, heat pass through shielding case 50, shielding case 60 to other layer of structure conduction respectively.
Due to the specific usage mode of smart camera, when manpower, which directly holds camera, to be imaged, the working time is not
Can be very long, therefore calorific value is not too large, surface temperature is normal.But when needing to shoot for a long time, such as when lasting
When shooting 45min or more, equipment heating amount increases, and the temperature excursion of fuselage causes manpower extremely uncomfortable when directly holding, and
Since 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, arranges phase-change heat-storage material between shielding case 60 and shell 1
61, phase-change heat-storage material 47 is arranged between circuit board 4 and camera lens 7, and phase transformation storage is arranged between circuit board 4 and shell 1
Hot material 41 arranges phase-change heat-storage material 32 between battery 3 and display screen 2.
It is chip respectively by the sequence of calorific 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 the minimum of the decalescence temperature range of phase-change heat-storage material from
Arriving small sequence greatly is phase-change heat-storage material 53 and phase-change heat-storage material 61, phase-change heat-storage material 32,47 and of phase-change heat-storage material
Phase-change heat-storage material 41.By choosing thermal coefficient appropriate, when camera is just started to work, either camera power consumption itself is 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 only play Heat Conduction Material
Effect.When camera power consumption increases on this basis, either camera causes power consumption itself very high using time increase, 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, the constant and camera lens temperature of camera surface temperature is kept to can satisfy requirement.
Therefore, pass through 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
With phase-change heat-storage material 41, camera can be allowed to keep certain temperature, be 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, shake of manpower itself can also affect shooting quality, thus use for a long time can all be used when camera it is some external
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, it is used as external device for the hand-held self-shooting bar 8 that camera assembly is connect with its shell 1, the junction of the two is constituted
Thermo-contact, and the external device uses Heat Conduction Material.Therefore, it when using hand-held self-shooting bar 8 as external device, will install outside
Standby a part as camera integral heat sink system, greatly increases heat dissipation area, further alleviates the heat dissipation pressure of camera itself
Power.
[embodiment two]
As shown in Fig. 2, being to use a kind of heat storage type temperature control of mobile device proposed by the present invention
The smartwatch of method processed.
Smartwatch 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 ', shielding case 50 ', chip 6 ', shielding case 60 ' form.Wherein chip 5 ', chip 6 ' are main
Pyrotoxin, heat passes through shielding case 50 ', shielding case 60 ' to other layer of structure conduction respectively.
The present embodiment uses a kind of heat storage type temprature control method of mobile device proposed by the present invention, in shielding case 50 '
Phase-change heat-storage material 53 ' is arranged between battery 3 ', and phase-change heat-storage material is arranged between shielding case 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 sequence of calorific value from big to small in the stacked structure of smartwatch in the present embodiment
5 ' and chip 6 ', battery 3 ', display screen 2 ', circuit board 4 ', therefore most by the decalescence temperature range of phase-change heat-storage material
The sequence 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
Thermal coefficient appropriate, when wrist-watch is just started to work, either wrist-watch power consumption itself is not high, phase-change heat-storage material 32 ',
Not decalescence only plays 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 call cause power consumption itself very high, then phase-change heat-storage material 53 ' and phase-change heat-storage material 61 ', phase transformation are stored up
Hot material 32 ' can start decalescence, keep the constant of watch dial temperature, until battery exhausts, watch dial temperature
It can maintain within specified value always.
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, setting value is no more than.
For those skilled in the art, revealed structure and principle various other phases can be obtained according to the present invention
The change and deformation answered, and all these change and deformation belongs to protection category of the invention.
