Mobile phone and manufacturing method thereof

Abstract

The present invention discloses a mobile phone which comprises a heat generating element with a heat generating surface, a heat radiation element with a heat absorbing surface, and a phase change thermal conduction material layer which is connected between the heat generating surface of the heat generating element and the heat absorbing surface of the heat radiation element, wherein the phase change thermal conduction material layer has a phase change point temperature and is made by the screen printing process, and the gap between the heat absorbing surface and the heat generating surface is smaller than or equal to 0.1 mm. The invention also discloses a manufacturing method of the mobile phone. Through the above mode, when the temperature of the heat generating element of the mobile phone reaches or exceeds a phase change point temperature, the phase change thermal conduction material layer is changed into a melt state from a solid state and fills the gap between the heat generating element and the heat radiation element so as to transfer the heat of the heat generating element to the heat radiation element, and the heat radiation performance of the mobile can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for manufacturing a mobile phone and a mobile phone using the method. Background technique [0002] With the improvement of people's living standards, mobile phones have been widely used in public life, and almost everyone has a mobile phone. In addition to being able to satisfy users to make calls, mobile phones also provide users with various entertainment functions, such as watching movies, playing games or listening to music on mobile phones. However, watching movies, playing games or listening to music on the mobile phone will consume a lot of power of the mobile phone, and the mobile phone will heat up after a long time. [0003] The heat dissipation problem of mobile phones has always been an urgent problem to be solved by major manufacturers, but there has been no major breakthrough.

However, watching movies, playing games or listening to music on the mobile phone will consume a lot of power of the mobile phone, and the mobile phone will heat up after a long time

[0003] The heat dissipation problem of mobile phones has always been an urgent problem to be solved by major manufacturers, but there has been no major breakthrough. Most mobile phones are equipped with heat dissipation elements on their heating elements for heat dissipation, such as setting radiators or coatings on the heating elements. Cloth heat-conducting silica gel, although the radiator or heat-conducting silica gel can dissipate the heat of the mobile phone to a certain extent, but its heat dissipation effect is not ideal, making the overall heat dissipation performance of the mobile phone poor
