Solar heat-collecting tube electricity generating device

Abstract

The invention discloses a solar heat-collecting tube electricity generating device comprising a connecting rod and heat absorbing plates. The two sides of the connecting rod are connected with the heat absorbing plates. The surfaces of the heat absorbing plates are connected with heat absorbing convex blocks. Heat conducting rods are arranged in the heat absorbing plates, an inner cavity is formedin the connecting rod, a heat conducting plate is connected between the heat conducting rods and the inner cavity, and the heat absorbing plates and the heat absorbing convex blocks are connected with the heat conducting plate through the heat conducting rods. The absorbing area of the electricity generating device and solar rays can be increased, solar rays are absorbed to the maximum extent, the working efficiency of the electricity generating device is improved, and heat loss is reduced. Dust and impurities on the surfaces of the heat absorbing plates can be cleared, so that the surface cleanliness of the heat absorbing plates is guaranteed, and the heat absorbing effect of the heat absorbing plates is guaranteed; manual cleaning is not needed, manpower is saved, and the service life of the heat absorbing plates is prolonged; and the heat absorbing plates are convenient to replace, the use cost of solar heat-collecting tubes is reduced, and the production costs of the solar heat-collecting tubes is reduced.

Description

technical field [0001] The invention relates to the technical field of the internal structure of a solar heat collecting tube, in particular to a solar heat collecting tube power generation device. Background technique [0002] Solar energy is a kind of renewable new energy, which has a wide range of functions in people's life and work, one of which is to convert solar energy into electrical energy, and solar cells use solar energy to work. The working principle of a solar thermal power station is to use the concentrated sunlight to boil water until it turns into water vapor, which is then used to generate electricity. Solar power generation can be divided into solar power generation and solar thermal power generation. [0003] The contact area between existing solar power generation devices and sunlight is relatively limited, it is difficult to improve the conversion rate of solar energy, which has a certain impact on the use of solar energy. Obstacles, and it is not conv...
