Abstract

The invention discloses a trough type light-condensing solar thermoelectric generator which comprises a trough type light-condensing device and a receiving tube. The receiving tube is opposite to the inner cambered surface of the trough type light-condensing device and comprises an inner wall and an outer wall, the inner wall defines a hollow cavity penetrating two ends of the receiving tube, the cavity between the inner wall and the outer wall is divided into multiple sealed filling cavities through metal heat-conducting units, each sealed filling cavity is full of heat-conducting oil, thermoelectric power generation pieces are installed on the side close to the hollow cavity, in the inner wall, in the linear direction, and covers the inner wall partially or wholly, and water-cooling pieces are installed on the cooling face of the thermoelectric power generation pieces. The interlayer cavity of the receiving tube is filled with heat-conducting oil, the heat-conducting oil has certain heat storage effect, and even if sunlight is interrupted, power generation can be also sustained for a period of time. The fluctuation changing with sunlight during electric energy output is reduced, the cavity between the inner wall and the outer wall is discontinuous, the inner wall and the outer wall are still partially connected through the metal heat-conducting units made of aluminum alloy and the like, and the problem that external heat cannot be transferred to the inner wall due to poor heat-conducting performance of the heat-conducting oil is avoided.

Description

technical field [0001] The invention relates to a trough-type concentrating solar thermoelectric generator utilizing the thermoelectric power generation technology of solar light and heat. Background technique [0002] Solar power is a technology that uses green energy to generate electricity. At present, there are mainly two types of solar energy utilization: photovoltaic and photothermal. The former mainly utilizes the light energy of solar energy to generate electricity through the photovoltaic effect. The latter uses solar energy to heat the heat medium for subsequent use. Compared with thermal power generation, hydropower generation and other technologies, solar power generation has the advantages of no mechanical rotating parts and simple installation. Compared with photovoltaic power generation, solar thermoelectric power generation can further utilize the thermal energy in solar energy through the Seebeck effect of semiconductor materials, and the heat that is not...
