Technical Field

[0001] The present invention relates to the technical field of power generation, and specifically to a semiconductor thermoelectric power generation system applicable to polar regions. Background Art

[0002] A semiconductor thermoelectric power generation system is a power generation system that directly converts thermal energy (temperature difference) into electrical energy based on the thermoelectric effect. It has the advantages of simple structure, high reliability, no noise, and maintenance-free, and shows broad application potential in many fields. However, due to its own structural limitations, the existing semiconductor thermoelectric power generation system has the following problems when applied to polar environments: First, the existing semiconductor thermoelectric power generation system uses a cooling fan or a circulating water pump as the cold source, resulting in poor heat dissipation at the cold end, and thus low power generation efficiency. Second, the starting method of the existing semiconductor thermoelectric power generation system is active starting, that is, it is necessary to supply power to the cold source (cooling fan or circulating water pump) through an external power source to make the semiconductor thermoelectric power generation chip start generating electricity, thereby starting the system. Therefore, the existing semiconductor thermoelectric power generation system needs to be equipped with an additional external power source, resulting in inconvenient use and high usage costs. Based on this, it is necessary to invent a semiconductor thermoelectric power generation system applicable to polar regions to solve the problems of poor heat dissipation at the cold end and the need for an additional external power source when the existing semiconductor thermoelectric power generation system is applied to polar environments.

[0038] During operation, the working medium box 301 is pre-installed with liquid working medium, and the output end of the semiconductor temperature difference power generation chip 201 is electrically connected to an external load.

[0039] The specific working process is as follows: First, open the valve plate 103 and put the heat source into the heating box 101 for combustion. During this process, the outside air enters the heating box 101 through the smoke pipe 104 to ensure the continuity of combustion, and the smoke generated by the combustion is discharged outward through the smoke pipe 104.

[0040] Then, put large pieces of ice and snow into the ice crusher 501, set the working mode of the telescopic rotary cutting mechanism to the manual mode, and the telescopic rotary cutting mechanism performs telescopic rotary cutting on the large pieces of ice and snow in the ice crusher 501, thereby chopping them up. The chopped small pieces of ice and snow fall into the cooling box 401 to serve as a cold source.

[0041] Under the combined action of the heat source and the cold source, the working fluid undergoes cyclic phase change heat dissipation in the phase change heat dissipation device. The specific process is as follows: The heat generated by the combustion of the heat source is sequentially transferred to the working fluid tank 301 through the heat sink 102, the hot end of the semiconductor thermoelectric generator 201, and the cold end of the semiconductor thermoelectric generator 201, causing the liquid working fluid to evaporate into a gaseous working fluid. On the one hand, the gaseous working fluid rises to the heat exchange chamber 401a sequentially through the main heat dissipation pipe 303 and the main heat dissipation groove 302a. On the other hand, the gaseous working fluid rises to the heat exchange chamber 401a sequentially through the auxiliary heat dissipation pipe 304 and the auxiliary heat dissipation groove 302b. The gaseous working fluid in the heat exchange chamber 401a condenses into a liquid working fluid after heat exchange with the cold source. On the one hand, the liquid working fluid returns to the working fluid tank 301 sequentially through the main heat dissipation groove 302a and the main heat dissipation pipe 303. On the other hand, the liquid working fluid returns to the working fluid tank 301 sequentially through the auxiliary heat dissipation groove 302b and the auxiliary heat dissipation pipe 304. During this process, the cold source in the cooling box 401 melts into water after heat exchange with the gaseous working fluid, and the water flows into the water storage tank 402 through the water collecting pipe 403.

[0042] Based on the cyclic phase change heat dissipation of the working fluid, a temperature difference is maintained between the hot end and the cold end of the semiconductor thermoelectric generator 201, thereby causing the semiconductor thermoelectric generator 201 to start generating electricity and starting the system.

[0043] After the system is started, the semiconductor thermoelectric generator 201 supplies power to the controller 502, the telescopic rotary cutting mechanism, and the clamping mechanism on the one hand, and supplies power to an external load on the other hand. On this basis, set the working mode of the telescopic rotary cutting mechanism to the automatic mode. Under the control of the controller 502, the telescopic rotary cutting mechanism continues to perform telescopic rotary cutting on the large pieces of ice and snow in the ice crusher 501. At the same time, under the control of the controller 502, the clamping mechanism clamps the ice and snow accumulated and adhered to the inner side wall of the ice crusher 501, thereby scraping it off.

Then, pass the pin shaft 514 through the two front pin holes 509a and the two ear plates 515, so that the first drive gear 519 is separated from the transmission gear 508. Then, manually operate the handle 513 to rotate reciprocally. Driven by the handle 513, the second swing arm 512, the two guide rods 511, and the transmission gear 508 rotate reciprocally together. Driven by the two guide rods 511, the first swing arm 506, the screw rod 505, the cutter head 523, and the cutter 524 not only rotate reciprocally together, but also move reciprocally longitudinally together.
