Cooler of mobile communication terminal

Abstract

The invention discloses a cooling apparatus of a mobile communication terminal belonging to mobile communication terminal components. Above all, a vent hole is formed on upper case and lower case of a mobile communication terminal body, and a ventilation fan is fixed to a lower case to neighbor with the vent hole, so that the ventilation fan automatically drives when the air temperature inside the lower case exceeds a certain range, thus the air inside an upper case can be circulated and cooled in the vent hole. Compared with the existing mobile communication terminal, the heat cycle of mobile communication terminal is more smooth to prevent the temperature of mobile communication terminal from greatly rising, therefore the inconvenience of use is relieved and the life shortening of mobile communication terminal can be prevented, thus the reliability of mobile communication terminal can be increased.

Description

technical field [0001] The invention belongs to the scope of components of mobile communication terminals, in particular to a cooling device for mobile communication terminals. Background technique [0002] Generally speaking, the heating problem of mobile communication terminals has always existed, and with the emergence of third-generation terminals, the heating problem is becoming more serious, and compared with bar-type terminals, the heating problem of flip-type terminals is more serious. In the case of a flip-type terminal, the upper flip with the LCD and the lower flip with the keypad cannot transfer heat to each other, so the lower flip gets hot while the upper flip hardly changes in temperature. [0003] In addition, large-scale products such as computers use forced ventilation to the outside, but in terminals, because it is considered that the casing of the terminal should be completely isolated from the outside, no forced ventilation device is used.

Problems solved by technology

[0004] In the above-mentioned existing mobile communication terminal in daily use, if the power supply of the mobile communication terminal is in the open state, especially when the mobile communication terminal is used for a long time call, the heat generated by the battery 150 will be as follows: figure 1 As indicated by the arrow in the figure, the circulation only circulates inside the lower casing 120 of the mobile communication terminal body 100, thereby causing the phenomenon of overheating of the lower casing 120 of the mobile communication terminal body 100, which often causes inconvenience to users. The problem that the lifespan of mobile communication terminals is shortened accordingly
