Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic diagram illustrating a structure of a mobile terminal according to an exemplary embodiment. As shown in fig. 1, the mobile terminal includes a housing 10, and further includes: a display screen (not shown) and a thermally conductive plate 20. The display screen is disposed inside the housing 10. The heat conducting plate 20 is disposed on the back of the display screen, and the heat conducting plate 20 is provided with a predetermined number of openings 201, and the heat conducting plate 20 is used for supporting the display screen and conducting the heat generated by the display screen.
This disclosure sets up heat-conducting plate 20 at the back of display screen, can support this display screen when the display screen is pressed, and this heat-conducting plate 20 can conduct the heat that the display screen produced and reduce its temperature. In the present disclosure, the heat conducting plate 20 is provided with the preset number of openings 201, which can exhaust air, reduce the weight of the heat conducting plate 20, and reduce the weight of the mobile terminal; and is beneficial to the stress release of the heat conducting plate 20 and reduces the deformation quantity. In addition, the holes are simply and conveniently made on the heat conducting plate 20, a special punch is not required to be configured, and the production difficulty is reduced.
In an embodiment of the present disclosure, the heat conducting plate 20 is fixed on the housing 10 and is spaced from the display screen by a certain distance to accommodate the deformation of the display screen after being pressed, so as to improve the control accuracy of the display screen. The distance can be set according to actual needs. In another embodiment, the display screen can be directly disposed on the heat conducting plate 20, so that the heat conducting plate 20 can directly conduct the heat generated by the display screen, thereby improving the heat conducting efficiency of the heat conducting plate 20.
In practical applications, the display screen is usually square. In an embodiment of the present disclosure, the area of the heat conducting plate 20 is larger than that of the display screen, and the shape thereof may be set to be square. For example, the width and length of the heat conductive plate 20 are respectively greater than those of the above-described display screen. Thus, when the area of the heat conducting plate 20 is larger than that of the display screen, the interference of the display screen can be avoided, and the heat dissipation area can be increased. Of course, in order to increase the heat dissipation area, the area of the heat conduction plate 20 may be as large as possible, and those skilled in the art may set the heat conduction plate according to specific scenarios, which is not limited in the present disclosure.
In an embodiment of the present disclosure, the openings 201 of the heat conducting plate 20 are distributed according to a predetermined rule. For example, the preset rules may be distributed in rows (bottom left to top right in fig. 1), may be distributed in columns (top left to bottom right in fig. 1), may be distributed "back", and the like. It can be understood that the predetermined number can be set according to the material of the heat conducting plate 20, the supporting force required to be provided to the display screen, and the stress of the heat conducting plate 20, and the predetermined number is as large as possible under the condition of satisfying the supporting force and the stress. The skilled person can choose according to specific scenarios, and the present disclosure is not limited.
In another embodiment of the present disclosure, since other circuits or batteries may exist on the back of the mobile terminal (the front of the display screen corresponds to the front of the mobile terminal), the diameter of each of the openings of the predetermined number may be different, and the local heat conduction of the heat conducting plate 20 may be adjusted by the size of the opening, so as to prevent the heat generated by the display screen from affecting the working performance of other circuits or batteries. In one embodiment, the diameter of each opening can be the same, so that the same punch can be used for realizing the opening, the manufacturing process can be simplified, and the manufacturing efficiency can be improved. In addition, the interval between two adjacent openings can be set by the supporting force, stress, material, etc. of the heat conducting plate 20, and the interval between two adjacent openings can be as small as possible under the condition of satisfying the supporting force and stress.
Take the mobile terminal who adopts 5.5 cun display screen as an example, the diameter of trompil can set up to 2.5 ~ 3.5mm, and the interval of two adjacent trompils sets up to 14 ~ 16 mm. As shown in FIG. 1, the spacing D1 between two apertures in the row direction and the spacing D2 between two apertures in the column direction may be equal and set at 15mm, with each aperture being set at 3mm in diameter. The distance between the two outermost rows and the frame of the housing 10 may be set to 11 to 13mm, for example, 12 mm.
It should be noted that the diameter and the interval of the predetermined number of openings can be considered together, so that the heat conducting plate 20 achieves a better heat conducting efficiency under the condition of satisfying the strength of the heat conducting plate 20 (for example, providing sufficient supporting force and stress).
In an embodiment of the present disclosure, the heat conducting plate 20 may be made of a metal material such as aluminum, copper, or an alloy material such as an aluminum alloy, a copper alloy, or the like. It is understood that the thermally conductive plate 20 may be made of one or more of aluminum or aluminum alloy, copper or copper alloy. In an embodiment of the present disclosure, the heat conducting plate 20 is made of aluminum alloy, and a high heat conducting efficiency is achieved under the condition of satisfying the supporting force and stress. One skilled in the art can combine the characteristics of various materials, such as copper with high thermal conductivity but high density, copper with low thermal conductivity but low density and being soft, to select a suitable material for the heat-conducting plate 20, and the disclosure is not limited thereto.
In another embodiment of the present disclosure, the mobile terminal further includes a heat dissipation plate 30. The heat dissipation plate 30 is attached to a side of the heat conduction plate 20 away from the display screen, and the shape of the heat dissipation plate 30 matches with the shape of the heat conduction plate 20, and the heat dissipation plate 30 is used for dissipating heat conducted by the heat conduction plate 20 into a space.
In an embodiment of the present disclosure, the heat dissipation plate 30 is implemented by a graphite sheet. Since the graphite sheet has characteristics of ultra-high heat conductive performance, low heat resistance, light weight, etc., heat conducted by the heat conductive plate 20 can be rapidly dissipated into a space, and the weight of the mobile terminal can be reduced.
In an embodiment of the present disclosure, the area of the heat dissipation plate 30 is greater than or equal to the area of the display screen and is less than or equal to the area of the heat conduction plate 20. It can be understood that the larger the area of the heat dissipation plate 30, the better the heat dissipation effect. Those skilled in the art can adjust the area of the heat dissipation plate 30 according to the usage scenario of the heat dissipation plate 30, and the disclosure is not limited thereto.
In an embodiment of the present disclosure, in order to attach the heat dissipation plate 30 to the heat conduction plate 20 precisely, as shown in fig. 1, at least one first positioning hole 202 is further disposed on the heat conduction plate 20. The position of the first positioning hole 202 can be set according to the use scene. Accordingly, the heat dissipation plate 30 is provided with a second positioning hole 301 matching each first positioning hole 202. As shown in fig. 2, when the heat dissipation plate 30 is attached to the heat conductive plate 20, the first positioning hole 202 and the matching second positioning hole 301 can be aligned. Of course, it is also possible to place a screw check in the positioning hole to fix the heat conductive plate 20 and the heat radiating plate 30 to the case 10.
In yet another embodiment of the present disclosure, some of the above technical problems may be solved. For example, the heat conductive plate 20 may be provided with a first predetermined number of openings in a first designated area and a second predetermined number of openings in a second designated area of the heat dissipation plate 30. As shown in fig. 3, a first predetermined number of openings 201 are provided in an upper half portion (a portion corresponding to an upper left corner in fig. 3) of the heat conductive plate 201, and a second predetermined number of openings 302 are provided in a lower half portion (a portion corresponding to a lower right corner in fig. 3) of the heat dissipation plate 30. After the heat dissipating plate 30 is attached to the heat conducting plate 20 and the first predetermined number of openings 201 and the second predetermined number of openings 302 are overlapped, as shown in fig. 4, all the openings may be distributed over the entire area of the heat dissipating plate 30. Thus, the heat conductive plate 20 can conduct heat generated from the display screen and then be dissipated into the space by the heat dissipation plate 30. The gas between the upper half of the heat radiating plate 30 and the upper half of the heat conductive plate 20 can be discharged through the opening 201; the gas between the lower half of the heat radiating plate 30 and the lower half of the heat conductive plate 20 can be discharged through the opening 302. The embodiment of the disclosure can also achieve the effect of reducing the moving weight, and is beneficial to the stress release of the heat conducting plate and the reduction of the deformation amount. In addition, the number of openings in the heat dissipation plate 30 can be reduced, which can reduce the difficulty of production.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
