A multi-lens solar heat collector

Abstract

The invention provides a multi-lens solar heat collection device. The device includes a water tank and a photothermal conversion element. The upper end of the water tank is an open structure. The photothermal conversion element floats on the upper part of the water tank. Glass cover, the transparent glass cover is an arc-shaped structure, the top of the transparent glass cover is provided with a steam outlet pipe, and the outer wall of the transparent glass cover is provided with a plurality of convex lenses in a convex shape, and the convex lenses are evenly distributed on the outer wall of the transparent glass cover , the focal point of the convex lens falls on the light-to-heat conversion coating to increase the absorption of solar energy. In the present invention, a plurality of uniformly distributed convex lenses are arranged on the outer wall of the transparent glass cover, so that the solar energy can be better concentrated, so that even if the position of the heat collector changes, the concentrated absorption of solar energy can still be ensured, and the focus deviation caused by the direction of the setting position can be avoided. shift.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector system. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The total amount of solar radiation energy received by the earth's s...

[0007] The solar heat collection device applied for earlier (application number 201911353155.2) has achieved the purpose of generating steam and recovering steam by setting a glass cover, but the solar heat collection device of the previous application has poor heat collection effect, especially due to the occurrence of setting deviation. The problem that the heat collecting part is out of focus
