Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Fig. 1,2, shown in 3 and 4, the present invention is a kind of intelligent phase-change heat sink, comprises phase-change material container 1, serpentine heat exchanger 2, magnetic valve 3, temperature sensor 4, microcontroller 5, pipeline 6, and reload bolt 7.Heat exchanger 2 to be located in phase-change material container 1 and to draw outside phase-change material container 1 by pipeline 6; Phase-change material 8 is filled with in phase-change material container 1; Magnetic valve 3 is located on pipeline 6; Temperature sensor 4 to be located on phase-change material container 1 and to stretch in phase-change material container 1.Microcontroller 5 drives high power device magnetic valve 3, and by temperature sensor 4 perception phase-change material real time temperature then microcontroller 5 Controlling solenoid valve 3 of giving an order open, make cold water enter heat exchanger 2 from pipeline 6 and carry out heat exchange with phase-change material, inside such phase-change material container 1, phase-change material keeps transition, temperature constant, and then the temperature difference of stable thermo-electric generation system, thermo-electric generation system regulated output voltage can be made.
