Problems solved by technology

[0005] However, the preparation process of the lower substrate 52 needs to be carried out in a relatively high vacuum insulation environment, and must be heated to a relatively high temperature, and the production process is complicated.
Therefore, the cost in the preparation process of the lower substrate 52 is relatively high, thereby correspondingly making the cost of the solar panel heat collector 500 relatively high, which is not suitable for popularization and application in a large area, and the solar panel heat collector 500 is relatively The conversion efficiency of solar energy is low

Abstract

The invention relates to a solar thermal collector, which comprises an upper substrate, a lower substrate, a heat absorbing layer, a frame bracket and a plurality of supports, wherein the upper substrate and the lower substrate are arranged oppositely; the frame bracket is arranged between the upper substrate and the lower substrate; the upper substrate, the lower substrate and the frame bracket form a cavity together; and the heat absorbing layer is arranged on the upper surface of the lower substrate positioned in the cavity. The plurality of the supports are arranged in the cavity at intervals, and are contacted with the upper substrate and the heat absorbing layer respectively. The heat absorbing layer has a carbon nano tuber structure.

Description

technical field [0001] The invention relates to a solar heat collector. Background technique [0002] With the development of modern industry and society, human society is increasingly dependent on resources and energy. As we all know, the resources and energy on the earth are limited, so in various economic, political, and scientific research activities, the issue of resources and energy has become the primary issue. And because some resources can be recycled and reused through some artificial processes. Therefore, the problem of energy is more prominent. Solar energy is the most abundant energy available to human beings, and it is also the cheapest, cleanest, and most promising energy source. Solar cells and solar collectors are the main ways to directly utilize and absorb solar energy. Compared with solar cells, solar collectors have higher efficiency, much higher than other solar energy utilization methods. However, due to the limitations of structure and materials,...
