Heat dissipation case of thermal interface materials in 5G mobile phones

5G mobile phones are a symbolic product of 5G communication applications. 5G mobile phones have great advantages, such as being able to experience ultra-high download speeds and extremely low network delays, and customer experience is good. However, the disadvantages of 5G mobile phones are also obvious. The heat is much greater than that of 4G mobile phones.

Heat generation is inevitable when the mobile phone is running, and the high temperature causes the mobile phone system to freeze and the battery life of the mobile phone is depleted, especially when playing games, the impact of high temperature on the mobile phone is more obvious. Mobile phone manufacturers are also working hard to try various cooling solutions, hoping to minimize the heat generation of mobile phones.

The cooling system composed of heat pipes, heat sinks, and fans is currently the most commonly used cooling method for equipment. However, due to the limited size of mobile phones, it is difficult to install large components such as fans in mobile phones. Heat dissipation on the back.

Thermally conductive interface material is a material commonly used to deal with heat conduction problems in electronic equipment, such as thermally conductive silicone grease, thermally conductive gel, thermally conductive silicone sheet, etc. The contact area between the two is not much, and there are still a large number of uncontacted areas. The heat conduction between the heat source and the heat dissipation component will be resisted by the air, so the function of the thermal interface material is to effectively reduce the contact thermal resistance between the two and eliminate the gap. Inner air, thereby improving the heat dissipation effect of 5G mobile phones.
