碩士 === 崑山科技大學 === 電子工程研究所 === 107 === The research on the high-temperature solar thermal energy collection system in this paper is because solar thermal energy is most commonly used in solar water heaters, but these water heaters do not exceed 80 degrees Celsius in any way , so they cannot be used in any industry. Therefore, in order to solve this problem, this paper is the use of high temperature solar collector system focusing lens can focus sunlight can reach a temperature of 200 ° C and then heat absorption of focusing plate, flow through the heat absorbing plate guide tube The internal fluid of the tube is heated. When the heat energy is absorbed by the fluid inside the draft tube, the temperature of the fluid rises. When the temperature of the fluid rises, the fluid will move upwards to the hot water end due to the density becoming smaller, and the heat energy is carried to the inside of the heat storage tank. The colder fluid will enter the cold water end due to the higher density, and it can be heated in the circulation. In this way, the solar heat energy of no more than 40 degrees Celsius can be converted into high temperature heat of more than 200 degrees Celsius without spending a lot of energy. By making expensive and huge high-temperature collectors , you can use low-temperature solar heat 24 hours a day, 7 days a week, in the hot climate of Taiwan.
