Abstract

The invention provides a heat radiating device which comprises the components of a heat conduction module that comprises a closed heat conduction pipe, wherein the heat conduction pipe is internally provided with a heat conduction liquid storage box for storing heat conduction liquid, the heat conduction liquid storage box sufficiently contacts with a heating area in a terminal, the heat conduction pipe is provided with one or a plurality of power generator modules, blades of the engine module are arranged in the heat conduction pipe, the heat conduction liquid flows along a preset path of the heat conduction pipe after heat-absorption and expansion, thereby pushing the blades of the power generator module for generating electric energy, and finally the heat conduction liquid flows back to the heat conduction liquid storage box; the engine module which generates electric energy through pushing of the heat conduction liquid and outputs the electric energy to a power supply management module; and a power supply management module which charges the battery of the terminal by means of the received electric energy. The heat radiating device has advantages of realizing quick heat radiation of a portable terminal product, performing energy recycling on the heat conduction liquid in flowing after heat-absorption and expansion, and storing the recycled electric energy for prolonging duration time of the portable terminal product.

Description

technical field [0001] The invention relates to the communication field, in particular to a heat dissipation device. Background technique [0002] With the continuous improvement of the performance of portable terminal products, the problems of battery life and heat dissipation have become more and more prominent. At present, battery life mainly relies on large-capacity batteries or mobile power sources; the heat dissipation method of portable terminal products is mainly based on the internal structure of a large number of graphite heat dissipation stickers, and the single-point heat generated by the main chip is evenly transmitted to the metal steel plate of the portable terminal product. Natural heat dissipation, the heat generated is not used effectively. [0003] A thermoelectric semiconductor can be used in a thermal power generation device alone. The thermoelectric semiconductor has a hot surface and a cold surface. The larger the temperature difference between the tw...
