It is difficult to discharge, which makes the handheld electronic device difficult to deheat, resulting in the failure of its internal electronic components due to overheating and shortened life or reduced performance.

In addition, there are also people in related industries who use a large amount of metal in hand-held electronic devices as the main material of the casing, especially aluminum-magnesium alloy, which has become a new generation of handheld because of its light weight, high strength and excellent appearance. Electronics The main outer casing material of the device, but the aluminum-magnesium alloy as the casing only has a better appearance than the casing made of ordinary plastic, the internal heat can not be discharged, and there is no antipyretic effect, and the internal electronic components are caused by The heat cannot be discharged so that its life is shortened.

As described above, the conventional disadvantages are as follows: 1. The heat cannot be effectively decomposed; 2. The life of the handheld electronic device is reduced.

Therefore, how to solve the above problems and problems in the past, that is, the inventors of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main object of the present invention is to provide a heat receiving portion on one side of the heat dissipating body and a heat dissipating portion on the other side. The heat receiving portion and the heat dissipating portion are respectively made of ceramic material and heat dissipating conductor. The handheld electronic device heat dissipating unit is configured to be equipped with a handheld electronic device to quickly dissipate the handheld electronic device.
