Background

Smart phones have become a necessity in daily life. However, with the increasing functions of smart phones, the internal structure is complex, and the heat dissipation requirements of the mobile phones are increased. Generally, heat dissipation of a mobile phone is realized by using heat-conducting gel on a chip or a module with large heat productivity of the mobile phone and then transferring the heat to a position with lower temperature in the mobile phone by means of a graphite sheet, a copper tube, a liquid copper tube and the like, so that the heat of the whole mobile phone is uniform, and the overall temperature of the mobile phone is reduced.

The heat dissipation is based on the means of homogenizing the heat inside the mobile phone, namely, the heat conduction gel is used for removing the heat conduction metal middle frame of the chip, and the heat is conducted to the low-temperature part of the mobile phone by means of a graphite sheet, a copper pipe and the like. After the temperature of the mobile phone is uniform, the whole heat dissipation of the mobile phone is also the heat exchange between the surface of the mobile phone and the external environment, if the heat exchange cannot be improved, the heat dissipation efficiency cannot be improved after the heat inside the mobile phone is uniform, and therefore the heat dissipation effect of the whole mobile phone is influenced.

Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

A battery cover 100 and an electronic device 200 of the electronic device according to an embodiment of the present application are described below with reference to fig. 1 to 3. It should be noted that the electronic device 200 may be a mobile phone, a tablet computer, a notebook computer, or a wearable device.

As shown in fig. 1 and 3, a battery cover 100 of an electronic device according to an embodiment of the present disclosure includes a cover body 110 and a phase change film 120.

Specifically, the cover main body 110 has a battery compartment 111, and the phase change film 120 is attached to the surface of the cover main body 110. It should be noted that the phase change film 120 may be a film structure made of a phase change Material (PCM-phase change Material), which is a substance that changes the state of a substance and provides latent heat when the temperature is constant, and the process of changing the physical property is called a phase change process, and the phase change Material absorbs or releases a large amount of latent heat during the phase change process. Commercially available phase change materials include: synthetic graphite material, heat-conducting gap filling material, heat-conducting gel or heat-conducting silica gel. When the temperature of the phase change film 120 is changed from low to high, the phase change film 120 is changed from a hard film to a soft film to absorb the temperature.

According to the battery cover 100 of the electronic device of the embodiment of the present application, by providing the phase change film 120 on the cover main body 110, the temperature inside the electronic device 200 can be balanced using the heat absorption characteristic of the phase change film 120, so that the temperature of the electronic device 200 is constant.

The phase change film 120 may be provided on an inner wall surface of the cap body 110. It should be noted that the cover main body 110 may be used to define a battery compartment 111, the battery compartment 111 may be used to house a battery, and the "inner wall surface of the cover main body 110" may be understood as a surface of the cover main body 110 facing the inside of the battery compartment 111. By disposing the phase change film 120 on the inner wall surface of the cover main body 110, the phase change film 120 can more easily absorb the temperature inside the electronic device 200, and thus the phase change film 120 can better balance the temperature inside the electronic device 200.

Here, the position of the phase change film 120 is not particularly limited, for example, the phase change film 120 may also be disposed on the outer wall surface of the cover plate main body 110, so that the phase change film 120 is convenient to release the absorbed heat to the outside of the electronic device 200, thereby facilitating to improve the heat dissipation efficiency of the electronic device 200. Here, the "outer wall surface of the cover main body 110" may be understood as a surface of the cover main body 110 facing the outside of the battery compartment 111.

In order to improve the heat dissipation efficiency of the electronic device 200, the cover plate main body 110 may be a heat conducting metal piece, and the heat conducting metal piece may rapidly absorb the heat inside the electronic device 200 and transfer the heat to the phase change film 120, so as to facilitate the rapid phase change of the phase change film 120, thereby rapidly balancing the heat inside the electronic device 200, and improving the condition of uneven distribution of the heat inside the electronic device 200. The phase transition temperature of the phase transition film 120 may be 28 ℃ to 35 ℃, thereby facilitating improvement of the uneven distribution of heat inside the electronic device 200.

Further, the battery cover 100 may further include a heat conductive layer 121. The heat conducting layer 121 may be sandwiched between the cover plate body 110 and the phase change film 120. That is, the cap main body 110, the heat conductive layer 121, and the phase change film 120 are stacked. The heat conducting layer 121 can be used for absorbing heat, so that the heat can be quickly transferred to the phase change film 120, the heat distribution inside the electronic device 200 can be quickly balanced, and the condition that the heat distribution inside the electronic device 200 is uneven is improved.

In order to facilitate disposing the heat conductive layer 121 and the phase change film 120 on the cover main body 110, the heat conductive layer 121 may be a heat conductive adhesive layer having adhesiveness, so that the phase change film 120 may be adhered to the cover main body 110 by the adhesiveness of the heat conductive layer 121. It should be noted that the position of the heat conduction layer 121 is not limited to this, for example, as shown in fig. 2, the battery cover 100 may further include a heat conduction layer 121, and the heat conduction layer 121 is disposed on the side of the phase change film 120 away from the cover plate main body 110. That is, the phase change film 120 is sandwiched between the heat conductive layer 121 and the cover plate body 110, that is, the cover plate body 110, the phase change film 120, and the heat conductive layer 121 are stacked. Further, the thickness of the heat conductive layer 121 and the thickness of the phase change layer may be equal.

As shown in fig. 1 to 3, an electronic device 200 according to an embodiment of the present application includes: battery cover 100, center frame 210 and display assembly 220.

Commercially available phase change materials include: synthetic graphite material, heat-conducting gap filling material, heat-conducting gel or heat-conducting silica gel. When the temperature of the phase change film 120 is changed from low to high, the phase change film 120 is changed from a hard film to a soft film to absorb the temperature.
