[0162] Solar thermal collector temperature difference power generation principle:

[0163] Based on the principle of semiconductor thermoelectric power generation, an open circuit voltage is generated when there is a temperature difference between the hot end and the cold end of the semiconductor thermoelectric module, and the open circuit voltage increases with the increase of the temperature difference. Solar energy is used to provide a heat source for the thermoelectric module, and wind power is used to cool the cold source of the power generation module, and a concentrated solar thermoelectric power generation device is designed. The sunlight irradiates on the trough parabolic reflector, and after reflection, it is concentrated to the focal line position. On the focal line, a heat collector, TEG, flat heat pipe, and fin heat sink are placed from bottom to top to form a semiconductor thermoelectric power generation device. The hot end of the TEG absorbs heat through the heat collector, and the cold end of the TEG uses a flat heat pipe to heat the aluminum fin heat sink with high conductivity. The evaporation section of the flat heat pipe is connected to the cold end of the TEG, and the condensation section is connected to the fin heat sink. The hot and cold ends of the TEG generate temperature differences to output electrical energy.

[0164] Energy saving and emission reduction principle:

[0165] Based on semiconductor temperature difference power generation technology, the abundant solar energy resources on the top of the tent are used to provide thermal energy for the hot end of the temperature difference power generation module, and the cold end dissipates heat through natural air cooling.

[0166] At the hot end, sunlight is incident on the parabolic concentrator and is reflected and converged at the focal line, and the flat receiver receives heat energy at the focal line. Silicone grease with good thermal conductivity is evenly coated on both sides of the thermoelectric module to reduce energy loss, so that the TEG hot end absorbs heat from the collector, and the gaps are filled with asbestos to reduce heat dissipation at the hot end. To enhance the heat dissipation at the cold end, when there is a temperature difference between the two ends of the heat pipe, the liquid in the evaporation section will vaporize quickly and bring the heat to the condensation section at high speed. The greater the temperature difference between the two ends, the faster the evaporation speed. After condensation and liquefaction in the condensation section, it flows back to the evaporation section through capillary action. This cycle repeats, continuously bringing heat to the low-temperature end, and the heat dissipation at the cold end is enhanced. The condensation section of the flat heat pipe is connected to the fin radiator, which uses air-cooled natural cold resources to increase the temperature difference between the two ends of the heat pipe.

[0167] Two sets of power generation devices are installed on the top of the tent through slide rails. They can receive solar energy from all angles by adjusting their directions. By connecting with modular components, the electrical energy is stored in batteries, and power is generated to drive small-power electrical appliances and tent heating pads, achieving energy-saving and emission-reduction effects while maintaining thermal comfort in the tent.

Furthermore, a concentrating solar temperature difference power generation tent is provided, and the contents are as follows: The temperature difference power generation technology is a solid-state energy conversion technology based on the Seebeck effect, and has the characteristics of simple structure and high reliability.

[0174] The Seebeck effect, also known as the first thermoelectric effect, refers to the thermoelectric phenomenon that the potential difference between two substances is caused by the temperature difference between two different electrical conductors or semiconductors. The essence is that when two metals come into contact, a contact potential difference will be generated, which is caused by the different electron overflow work functions of the two metals and the different electron concentrations in the two metals.

[0180] Past experiments have shown that the common battery charging efficiency on the market is about 85%, which can achieve the charging and discharging efficiency required by the product. Taking Beijing as an example, the product can generate 686.9KW·h of electricity in summer and 213.6KW·h of electricity in winter. The heating pad (assuming it runs intermittently for 4 hours a day) consumes about 22KW·h of electricity, and the part that can be used by the battery system is about 124.3KW·h, which is enough for ordinary small electrical appliances for camping. It is also enough to prove the feasibility of the product.
