Method and system for cooling intelligent terminal

The invention provides a method and a system for cooling an intelligent terminal. The method for cooling the intelligent terminal comprises the steps as follows: a heating device on a mainboard of the intelligent terminal is connected with a thermo-semiconductor; electric energy is generated through a temperature difference between a high-temperature side and a low-temperature side of the thermo-semiconductor; and the electric energy generated by the thermo-semiconductor is used for charging a battery of the intelligent terminal through a charging module of the intelligent terminal, wherein a boost-up circuit for enabling the voltage output by the thermo-semiconductor to conform to the charging voltage of the charging module is arranged between the thermo-semiconductor and the charging module of the intelligent terminal. According to the method and the system, the heat generated by heating of the intelligent terminal can be converted into electric energy for charging the intelligent terminal, so that the heat can be recycled; the heat generated by the intelligent terminal is emitted; power consumption of the intelligent terminal is also reduced; and the system is simple and efficient, and has relatively high versatility and practicability.
