Embodiment 1

[0025] like figure 1 Shown is a smart camera that adopts a thermal storage temperature control method for mobile devices proposed by the present invention.

[0026] The smart camera in this embodiment has a stacked structure consisting of a shell 1, a display screen 2, a battery 3, a circuit board 4, a chip 5, a shield 50, a chip 6, a shield 60, and a lens 7 in the thickness direction. Among them, chip 5 and chip 6 are main heat sources, and their heat is conducted to other layer structures through shielding cover 50 and shielding cover 60 respectively.

[0027] Due to the specific way of using the smart camera, when the camera is directly held by the hand for video recording, its working time will not be very long, so the heat will not be too large, and its surface temperature is basically normal. However, when shooting for a long time, for example, when shooting continuously for more than 45 minutes, the heat generated by the device will increase, and the temperature of the...

Embodiment 2

[0033] like figure 2 Shown is a smart watch that adopts a heat storage temperature control method for a mobile device proposed by the present invention.

[0034] The smart watch in this embodiment has a shell 1', a display screen 2', a battery 3', a circuit board 4', a chip 5', a shield 50', a chip 6' and a shield 60' in the thickness direction. Layered structure. Wherein the chip 5' and the chip 6' are the main heat sources, and their heat is conducted to other layer structures through the shielding case 50' and the shielding case 60' respectively.

[0035] This embodiment adopts a heat storage type temperature control method for mobile devices proposed by the present invention. A phase change heat storage material 53' is arranged between the shield 50' and the battery 3', and a phase change heat storage material 53' is arranged between the shield 60' and the outer shell 1'. A phase-change heat storage material 61' is arranged between them, and a phase-change heat storage ...

Abstract

A heat storage type temperature control method for a mobile device. According to the calorific value of the stacked structure of the mobile device in the thickness direction, different phase change heat storage materials are respectively arranged for each layer, and the phase change heat storage materials are used as The heat conduction medium in contact with each other between the layers; wherein, the phase change heat storage material in contact with the layer with high calorific value in the laminated structure has the highest value of the phase change endothermic temperature range higher than that without contact with the layer phase change heat storage materials. Compared with the prior art, the beneficial effect of the present invention lies in: aiming at the characteristics of multiple transformations of the temperature distribution from the internal components to the outer casing of the mobile device, a plurality of different heat storage devices are arranged according to the stacked structure of the mobile device in the thickness direction Materials, to ensure the maximum efficiency gain of the use of heat storage materials, so that when the mobile device is working in a state of high power consumption, it can still effectively control its surface temperature not to exceed the set value.

Description

technical field [0001] The invention relates to temperature control and heat dissipation technology of electronic equipment, in particular to a heat storage type temperature control method of mobile equipment. Background technique [0002] With the improvement of miniaturization and high integration of electronic equipment, the heat dissipation problem of electronic equipment, especially mobile equipment, is becoming more and more serious. Large temperature control pressure. [0003] Faced with this situation, according to the characteristics of mobile devices such as smart cameras and smart watches, heat storage materials are used to thermally design such mobile devices so that their surface temperature can meet the requirements. Some cases, such as: Chinese invention application with application number 201610287111.4 "Mobile terminal and mobile terminal heat absorption method, heat absorption heat storage material production method", Chinese utility model application numb...
