Problems solved by technology

[0009] The above technology uses a separate concentrator and a silicon oxide or alumina nanofluid is passed through the hollow cavity, which has a high cost. At the same time, the concentrator has poor resistance to strong wind and dust pollution, and the loss of sunlight under dust cover Large, cannot be used in areas with strong winds and a lot of sand and dust
[0010] Existing water heaters have solved the problems of cost and wind resistance, and are relatively easy to remove sand and dust pollution. However, water heaters only produce hot water and cannot obtain high-grade electric energy.

Embodiment 2

[0041] The cross-section of the inner tube of the transparent long tube is designed as an elliptical double-convex lens, which has a shorter focal length and a more compact structure. The ellipse in this example has a major axis of 133 and a minor axis of 90. See diagram 2-1 .

Embodiment 3

[0043] The section of the inner tube of the transparent long tube is designed as a convex-concave lens with a relatively uniform thickness, so that the incident light is more uniform, which is conducive to improving the power generation efficiency of the battery. In this example, the four radii of the convex and concave surfaces are 100, 105, 200, and 205 respectively, and the width of the inner tube is 133, see Figure 2-2 .

Abstract

The invention relates to a solar water heater with a power generation function, which comprises a solar water heater and a sun tracker, wherein the solar water heater is fixed on the sun tracker. The solar water heater consists of a support, a water tank, transparent long outer tubes, transparent long inner tubes, a heat-superconductive tubes, a photovoltaic cell support and a photovoltaic cell, wherein the transparent long outer tubes and the transparent long inner tubes can be transparent single-layer glass tubes and can also be combinations of transparent glass and metal mixed tubes and transparent glass and plastic mixed tubes, the transparent long inner tubes are filled with any one of common water, softened water, purified water and mixed liquid of water and dibasic alcohol, the heat-superconductive tubes are installed, the photovoltaic cell support is installed outside the inner tubes and the photovoltaic cell is installed on the photovoltaic cell support. By using the transparent long tubes as natural light condensers, the purchase cost of separate condensers is greatly saved, the power generation function of the water heater is realized; and by filling the liquid capable of absorbing infrared light in the transparent long tubes, infrared light cannot irradiate the photovoltaic cell, the problem of efficiency decrease caused by heating of the photovoltaic cell because of light condensation is solved, the power generation efficiency of unit area is improved and the cost is reduced.

Description

technical field [0001] The invention relates to a system for simultaneously obtaining heat and electricity from solar energy with high efficiency and low cost, in particular to a solar water heater capable of generating electricity. Background technique [0002] Due to soaring oil prices and energy shortages, the development of the world economy and the improvement of people's living standards are seriously restricted. Countries are paying more attention to the use of renewable energy, especially solar energy. [0003] my country is rich in solar energy resources, the annual radiation in two-thirds of the area is greater than 20MJ / square meter, and the sunshine hours are more than 2200 hours. The development and utilization of solar energy has great potential. [0004] At present, solar energy utilization technologies mainly include basic methods such as photothermal conversion, photovoltaic power generation, and photochemical conversion. [0005] Photovoltaic cell power g...
