Abstract
The utility model relates to a portable electronic device, comprising a housing and a circuit board arranged in the housing. The circuit board is provided with a heating component and is also covered with a graphite flake; the graphite flake comprises a heat dissipation surface and a heat absorbent surface opposite to the heat dissipation surface; one end of the graphite flake bends so that the heat dissipation surface and the heating component are applied. According to the utility model, one end of the graphite flake bends so as to apply with the heating component, and accordingly the heat dissipation surface of the graphite flake can be applied with the heating component and a contact surface between the graphite flake and the heating component is the same with the heat dissipation surface, which substantially raises heat conduction and heat dissipation efficiency.
Description
Technical field
The utility model relates to a kind of electronic equipment, more particularly, relates to a kind of radiator structure of electronic equipment.
Background technology
In the past, the heat radiation of portable electric appts realized by aluminum hull, but because the aluminum hull volume is large and heavy, causes the portability of portable electric appts to be had a greatly reduced quality.Along with portable type electronic product more and more gentlier, more and more thinner trend, the product heat radiation of our a new generation can not rely on aluminum hull again, this just need to find a kind of new heat sink conception.
Graphite flake is a kind of outstanding Heat Conduction Material, but graphite flake has very strong anisotropy, and its thermal conductivity at in-plane can reach 1000W/m-K,, differs more than 100 times usually less than 10W/m-K in the thermal conductivity of thickness direction.This just makes, if the one side that graphite flake and thermal source are fitted is not radiating surface, its radiating effect is just had a greatly reduced quality.
The utility model content
The technical problems to be solved in the utility model is, for the defects of prior art, provides a kind of portable electric appts.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of portable electric appts, comprise shell and be arranged on the interior circuit board of described shell, described circuit board is provided with heater element, also be coated with graphite flake on described circuit board, described graphite flake comprises the radiating surface that is positioned at end face and the heat-absorbent surface that is positioned at the bottom surface, and an end bending of described graphite flake is so that described radiating surface and the applying of described heater element.
Portable electric appts described in the utility model, wherein, described shell comprises upper casing and the lower casing that is fastened and connected with described upper casing, is provided with described circuit board in described lower casing.
Portable electric appts described in the utility model wherein, also is provided with radome and electronic component on described circuit board, described heat-absorbent surface and described radome and electronic component are fitted.
Implement portable electric appts of the present utility model, have following beneficial effect: the utility model is fitted graphite flake one end bending with heater element, make the radiating surface of graphite flake to fit with heater element, and then to make face and the radiating surface that graphite flake contacts with heater element be the same face, greatly improved heat conduction and radiating efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the structural representation of a kind of portable electric appts preferred embodiment of the utility model.
Embodiment
As shown in Figure 1, in preferred embodiment of the present utility model, this portable electric appts comprises shell 100 and is arranged on the interior circuit board 101 of shell 100, circuit board 101 is provided with heater element 102, also be coated with graphite flake 103 on circuit board 101, this graphite flake 103 comprises the radiating surface 104 that is positioned at end face and the heat-absorbent surface 105 that is positioned at the bottom surface, and an end bending of graphite flake 103 is so that radiating surface 104 and heater element 102 applyings.It should be noted that the end face mentioned in the utility model and bottom surface are that view direction with Fig. 1 defines, and radiating surface 104 is also relative concept with heat-absorbent surface 105, therefore can not limits protection range of the present utility model with this.
In preferred embodiment of the present utility model, heater element 102 is often referred to CPU, PA etc.Can cause that when heat source temperature is too high Efficiency Decreasing even damages element, it is very important therefore heat being distributed in the very first time.Graphite flake is a kind of good heat conduction and heat sink material, but because graphite flake has anisotropy, its thermal conductivity on in-plane can be up to 1000W/m-K, and in the thermal conductivity of thickness direction usually less than 10W/m-K, therefore the end bending with graphite flake is fitted radiating surface 104 and heater element 102, so that the one side that graphite flake contacts with heater element 102 is the same faces with radiating surface 104, so just utilize graphite flake in the high thermal conductivity of in-plane well, improved the efficient of heat conduction and heat radiation.
Preferably, above-mentioned shell 100 comprise upper casing 106 and with the lower casing 107 that upper casing 106 is fastened and connected, be provided with circuit board 101 in lower casing 107.Understandable, upper casing 106 also can be one-body molded with lower casing 107.Also be provided with radome 108 and electronic component 109 on this circuit board 101, the heat-absorbent surface of graphite flake 103 and radome 108 and electronic component 109 are fitted.
The utility model is fitted radiating surface and the heater element of graphite flake, and making face and the radiating surface that graphite flake contacts with heater element is the same face, has greatly improved heat conduction and radiating efficiency.
Above embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow person skilled in the art scholar can understand content of the present utility model and implement accordingly, can not limit protection range of the present utility model.All equalizations of doing with the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
