Hereinafter, with reference to the accompanying drawings to embodiment of the present utility model is described in detail.However, it is possible in many different forms To implement the utility model, and the utility model should not be construed as limited to the specific embodiment that illustrates here.On the contrary, It is in order to explain principle and its practical application of the present utility model, so that the other technologies people of this area to provide these embodiments Member is it will be appreciated that various embodiments of the present utility model and the various modifications for being suitable for specific intended application.In the accompanying drawings, in order to For the sake of clear, the shape and size of element can be exaggerated, and identical label will be used to indicate all the time it is same or analogous Element.

In the accompanying drawings, for the sake of clarity, can exaggerate the shape and size of element, and identical label will all the time by For representing same or analogous element.

Fig. 1 is the structural representation according to the mobile electronic device of embodiment of the present utility model；Fig. 2 is the A-A along Fig. 1 The profile in direction

Reference picture 1, Fig. 2, according to the mobile electronic device of embodiment of the present utility model, including：Drain pan 10, face-piece 11, Control mainboard 20, heat generating member 30, heat-conducting piece 40, fin 50.It should be noted that the shifting according to embodiment of the present utility model Dynamic electronic equipment can also include other necessary parts.

Specifically, face-piece 11 is relative with drain pan 10, and the end of face-piece 11 is fixedly connected with the end of drain pan 10, so as to face-piece Receiving space is formed between drain pan.Control mainboard 20 is arranged in receiving space, and on face-piece 11.

Heat generating member 30 is arranged in control mainboard 20, and between control mainboard 20 and drain pan 10.Heat generating member is to move Dynamic electronic equipment maintains the significant components of work, meanwhile, heat generating member can produce substantial amounts of heat in normal work, and this is also to move The main source of dynamic electronic equipment heat.Heat generating member 30 includes central processing unit, but the utility model is not restricted to this, hair Warmware 30 can produce other chips of heat when can also be the work on mobile device.

Heat-conducting piece 40 is arranged on heat generating member 30, projection of the heat generating member 30 on heat-conducting piece 40 be fully located at heat-conducting piece 40 it Interior, heat generating member 30 is completely covered in heat-conducting piece 40, is advantageous in time transfer out the heat on heat generating member 30 and.It is new according to this practicality The material selection heat conductive silica gel of the heat-conducting piece 40 of the embodiment of type, but the utility model is not restricted to this, as long as heat conduction The material that coefficient is high, longitudinal heat conductivility is good can be as the material of heat-conducting piece 40.

Fin 50 is arranged on heat-conducting piece 40, and between heat-conducting piece 40 and drain pan 10, fin is by moving electricity The sheet structure composition of sub- device interior, sheet structure include radome and/or reinforcing plate and/or mobile device internal mode The protection cap of block, as long as the structural member of some unborn sheets of mobile device inside, or for protecting or for shielding, It can be used for forming fin.Sheet structure inside mobile electronic device is transformed again, designed between sheet structure Into continuous entirety, the fin 50 of a monoblock is formed, the scope of fin 50 is expanded, heat is had bigger conduction Area.Original sheet structure inside mobile electronic device is reasonably transformed, sheet structure is not only possessed originally Function, while also there is as fin 50 function of radiating, it is not necessary to additionally increase component, escapable cost, reduce and move The thickness of dynamic electronic equipment.

Specifically, projection of the heat-conducting piece 40 on fin 50 is fully located within fin 50, and fin 50 covers completely Lid heat-conducting piece 40, be advantageous to the heat that fin 50 absorbs rapidly and diffusion heat-conducting piece 40 conducts.

Specifically, there is interval between fin 50 and drain pan 10, according to embodiment of the present utility model, fin 50 with Between drain pan 10 at intervals of 0.2mm, be not directly contacted between fin 50 and drain pan 10, be to prevent office on fin 50 The drain pan for being transmitted to and being contacted with the region is concentrated heat in temperature higher region in portion's, causes drain pan local temperature too high, influences The experience sense of user.

Preferably, it is stamped to form according to aluminium flake of the fin 50 of embodiment of the present utility model from 0.3mm, but this Utility model is not restricted to this, and such as fin 50 can also select the good material system of the other suitable heat conductivilitys of copper sheet Into.Compared to the heat sink material graphite flake selected in traditional heat-dissipating scheme, aluminium flake price is relatively low, and can reuse.

It should be noted that tablet personal computer, intelligence can be for example according to the mobile electronic device of embodiment of the present utility model Energy mobile phone etc..

The radiation processes of the mobile electronic device of embodiment of the present utility model will be described in detail below.

When mobile electronic device normal work, heat generating member 30 can produce substantial amounts of heat, and now, heat-conducting piece 40 rapidly will Heat on heat generating member 30 is transmitted on fin 50, avoids heat from gathering；Because fin 50 has good heat conductivity Can, and area is larger, when heat-conducting piece 40 conducts heat to fin 50, heat will quickly be spread out, comparatively fast be distributed, until dissipating The heat that backing 50 absorbs reaches balance with the heat distributed；After fin 50 reaches thermal balance, heat by air equably Spread out into surrounding environment.

In summary, according to embodiment of the present utility model, by setting heat-conducting piece on heat generating member, mobile electron is transformed The sheet structure of device interior absorbs as fin, conducts the heat transmitted by heat-conducting piece, heat can be avoided to gather, Heat will be spread rapidly and equably radiate, it is simple in construction, cost is relatively low, thickness is relatively low, efficiently solve mobile electron and set Standby heat dissipation problem.

Although the utility model has shown and described with reference to specific embodiment, those skilled in the art will manage Solution：In the case where not departing from the spirit and scope of the present utility model limited by claim and its equivalent, can enter herein Various change in row form and details.
