Description

Technical Field

[0002] There are multiple heat generating areas on the tablet, including the CPU, graphics card and power supply. After working for a long time, a lot of heat will be generated. If the heat cannot be dissipated in time, the internal components will have to work in a high temperature environment, which may not only cause the system to run unstably and shorten the service life, but may even burn some components. As the tablet is small in size and thin in thickness, the heat dissipation capacity is limited. As the battery continues to heat up during the use of the tablet, it is easy for the tablet to malfunction or even cause circuit damage.

[0003] In the prior art, heat is generally dissipated by placing a discrete heat sink or a heat dissipation fan. Among them, the heat dissipation effect of the discrete heat sink is poor, and the heat dissipation fan is easy to break, and the heat dissipation and dust prevention effects cannot be taken into account at the same time, which affects the normal operation and service life of the components. In addition, due to the use of fans for heat dissipation, the noise is loud, the equipment stability is not high, it is inconvenient to use, the production cost is high, it is difficult to promote and apply, and it cannot meet consumer needs.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content
