As an example related to the present invention, the heat pipe includes first and second extensions extending in lengths in opposite directions from the housing to be symmetrical with respect to the housing.
As an example related to the present invention, one surface of the mobile terminal is formed with a hole through which air inside the mobile terminal can be discharged, and the other side is equipped with a fan capable of flowing air inside the mobile terminal.
According to the present invention having the above configuration, a heat pipe for transferring heat generated by the heat generating element to the heat dissipation unit is mounted inside the mobile terminal, and a housing for facilitating heat conduction between the heat generating element and the heat pipe is provided. In addition, a mobile terminal for dissipating heat from the heat generating element to the outside more quickly may be provided.
In addition, the structure and arrangement of the heat pipes may be variously modified to minimize the influence of the directionality of the heat pipes, thereby providing a mobile terminal having a structure for maximizing a heat dissipation effect.
In addition, by forming a hole in the mobile terminal case to naturally convection air inside the terminal or to force the convection by vibrating the terminal case, the heat of the heat generating element can be released to the outside not only by conduction but also by convection. Therefore, more efficient cooling can be achieved.
