Recently, as the performance and functions of such a mobile terminal are unimaginably developed, heat generated during operation is increasing. By the way, heat generated from the portable terminal must be cooled.

If it is not cooled, the user who mainly uses the mobile terminal by hand feels great inconvenience and anxiety. In the case of smart phones that are rapidly increasing in number of users, the heat is generated so that it is difficult for the user to hold in hand.

In addition, if the heat generated in the portable terminal is not cooled properly, the operation of the portable terminal is adversely affected. In some cases, an accident such as a failure of the portable terminal or an explosion may occur.

On the other hand, users who use a mobile terminal such as a mobile phone, a smartphone, or a tablet PC often use a case attached to the mobile terminal. The user uses the case to protect the portable terminal, to improve the grip of the mobile terminal, or to improve the aesthetics.

As the case material, silicon, plastic, or the like is mainly used. In general, the case surrounds the rest of the cell phone, except for the part provided with the LCD screen of the smartphone.

However, as described above, the conventional portable terminal case has only functions such as protection of the portable terminal, improved grip and improved aesthetics, and no technical considerations for cooling the heat generated in the portable terminal. It is not.
