Description

Radiator and electronic device with the radiator

Technical field

It is the present invention relates to a kind of radiator and with the electronic device of the radiator, in particular to a kind of active scattered Thermal and electronic device with the radiator.

Background technique

Space is smaller in electronic device such as mobile phone, such as radiates not in time, then its system easily runs shakiness because temperature is excessively high Fixed either function limitation, influences Operating ettectiveness.

A kind of existing heat dissipation design is that heat sink material is pasted near heating sources, and using thermal conduction characteristic, heat is passed Be handed to casing surface, and then carry out heat exchange with cool ambient air, above-mentioned radiating mode belongs to passive heat radiation, heat dissipation it is relatively slow and Effect is limited.

Another heat dissipation design is that mini-fan is arranged in electronic device, using fan generate enforceable air-flow by Heat in it is taken away.However, above-mentioned heat dissipation design need to occupy space in electronic device, and fan itself is a heat source, such as It is improper to be arranged, and ideal heat dissipation effect may be not achieved.

Summary of the invention

In view of the above problems, it is necessary to provide one kind without occupying exceptional space, and the preferable radiator of heat dissipation effect.

In addition, it is necessary to provide a kind of electronic devices with above-mentioned radiator.

A kind of radiator, the radiator include ontology and the lid that is set on the ontology, the ontology and the lid Cavity is formed, which is equipped with an at least pressing area, at least an air inlet and an at least venthole, presses the pressing Area may make the air-flow for being formed in the cavity and flowing to the venthole from the air inlet.

A kind of electronic device, the electronic device include radiator, which includes ontology and be set to the ontology On lid, the ontology and the lid form cavity, which is equipped with an at least pressing area, an at least air inlet and extremely A few venthole, presses the pressing area, may make the air-flow for being formed in the cavity and flowing to the venthole from the air inlet.

The radiator is set on the lid, it is therefore not necessary to occupy the space in electronic device, and the heat dissipation fills It is set to active heat dissipation, takes away the heat in electronic device by forming air-flow in the cavity, heat dissipation effect is preferable.

Main element symbol description

The present invention that the following detailed description will be further explained with reference to the above drawings.

Specific embodiment

Referring to Fig. 1, the radiator 100 of a preferred embodiment of the present invention is suitable for electronic device 200, as hand is mechanical, electrical Brain etc..The settable various electronic component (not shown) for supporting it to operate normally, the radiator 100 in the electronic device 200 The heat generated when for running to electronic device 200 radiates.In the preferred embodiment, it takes the mobile phone as an example, to this hair Bright electronic device 200 and radiator 100 is illustrated.

The radiator 100 includes ontology 10 and the lid 20 being set on the ontology 10, the ontology 10 and the lid 20 It is formed cavity 30 (see Fig. 2), above-mentioned electronic component is placed in the cavity 30.

Please refer to figs. 2 and 3, the lid 20 can be electronic device 200 rear cover, which is provided with an at least pressing area 21, An at least air inlet 22 and at least one venthole 23 corresponding with the air inlet 22.When the pressing area 21 is stationary state, the chamber Body 30 is enclosure space, and the movement for pressing the pressing area 21 can cause the variation that pressure is generated inside the cavity 30, and then cause The air-flow of the venthole 23 is flow to from the air inlet 22.In the preferred embodiment, which sets there are two pressing area 21, two A air inlet 22 and two ventholes 23, it will be understood that the quantity of the pressing area 21, the air inlet 22 and the venthole 23 is unlimited It can be one or more, and the quantity of the pressing area 21, the air inlet 22 and the venthole 23 can not be identical in two.

In the preferred embodiment, which including bottom wall 24 and encloses the side wall 25 for setting the bottom wall 24 and being formed, the pressing Area 21 is set to the bottom wall 24, and the air inlet 22 and the venthole 23 are opened in the side wall 25.

The pressing area 21 includes press section 211 and interconnecting piece 212.The press section 211 is to be formed by the lid 20 segmentation Sheet body, between the press section 211 and the lid 20 formed gap 213, the interconnecting piece 212 be set to the gap 213 and by this by Splenium 211 is connected with the lid 20, which is closed.The interconnecting piece 212 is made of elastic material, and the press section 211 is logical It crosses the interconnecting piece 212 to be connected with the lid 20, when pressing the press section 211, which occurs elastic deformation, so that should Press section 211 moves up and down with respect to the lid 20, and to form air-flow, the heat of the cavity 30 is brought to outside the electronic device 200. Since the interconnecting piece 212 closes the gap 213, the air-flow can't be somebody's turn to do during pressing through the gap 213 disengaging Cavity 30.

It is appreciated that the pressing area 21 may also set up the other positions such as ontology 10 or side wall 25 in the electronic device 200 On, as long as the air-flow can be formed.

In the preferred embodiment, which includes the first end 251 and the second end 252 that are oppositely arranged, should be into Stomata 22 is opened in first end 251, which is opened in the second end 252, each air inlet 22 and one of them Venthole 23 is corresponding, and the line between the corresponding air inlet 22 and the venthole 23 is perpendicular to first end 251 and second end Portion 252.It is appreciated that the air inlet 22 can not also be corresponding with the position of the venthole 23

It is appreciated that the air inlet 22 and the venthole 23 may also set up the other positions such as sheet in the electronic device 200 On body 10 or bottom wall 24, or the other positions of side wall 25 are set to, need to only be penetrated through with the cavity 30, can air-flow be flowed through i.e. It can.

In a further preferred embodiment, which further includes right respectively with the air inlet 22 and the venthole 23 The primary diaphragm 26 and secondary diaphragm 27 answered.Wherein, which is set to the inside of the first end 251, this second Diaphragm 27 is set to the outside of the second end 252.The inside refers to close to the direction of the cavity 30, and the outside refers to Direction far from the cavity 30.When pressing the pressing area 21 repeatedly, air-flow is generated in the cavity 30, which pushes first film Piece 26 and secondary diaphragm 27 stop pressing the pressing area 21 with respect to the air inlet 22 and the venthole 23 opening (as shown in Figure 2) When, which disappears, then the primary diaphragm 26 and secondary diaphragm 27 are with respect to the air inlet 22 and the venthole 23 closure (such as Fig. 3 It is shown), thus prevent water, dust and other sundries to enter in the cavity 30 from the air inlet 22 and the venthole 23.

Referring to Figure 4 together, in a further preferred embodiment, which further includes pushing component 40, the promotion Component 40 includes eccentric wheel 41, electric motor 42 and connecting rod 43, which passes through the connecting rod 43 and the electric motor 42 are connected, which is set to the inside of the pressing area 21, which can turn under the driving of the electric motor 42 It is dynamic, it is without the Manual press pressing area 21, it can be achieved that automatic to push the pressing area 21 to move up and down with respect to the lid 20 Heat dissipation.

The radiator 100 is set on the lid 20, it is therefore not necessary to occupy the space in electronic device 200, and institute Stating radiator 100 is active heat dissipation, takes away the heat in electronic device 200 by forming air-flow in the cavity 30, Heat dissipation effect is preferable.

In addition, those skilled in the art can also be in better embodiment claim of the present invention scope of disclosure and spirit Do various modifications, addition and the replacement in other forms and details.Certainly, these better embodiment spirit institutes according to the present invention Various modifications, addition and replacement for doing etc. variation, all should be included in better embodiment of the present invention range claimed it It is interior.
