A solar water heater

Abstract

The invention provides a solar water heater. The solar water heater comprises a water tank, a transparent glass plate, a thermal insulating layer, a heat-absorbing film and a heat collector; the heat collector comprises a collector pipe that comprises a heat-absorbing end and a heat-release end; the heat-release end is arranged in the water tank; the heat-absorbing film is arranged on one surface, facing the sun, of the heat-absorbing end of the collector pipe; the transparent glass plate covers an upper portion of the heat-absorbing end of the collector pipe; and the thermal insulating layer is arranged between the heat-absorbing end and the transparent glass plate. The solar water heater is provided with such components as the transparent glass plate, the thermal insulating layer, the heat-absorbing film and a baseplate, and therefore, the solar energy utilization efficiency of the water heater is improved and energy sources are saved.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar water heater. 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 surface ev...

Problems solved by technology

[0004] In general, solar water heaters use heat collecting tubes to absorb heat, but the heat collecting tubes may lose heat due to heat transfer problems, and because the fins are installed inside the heat collecting tubes, the fluid resistance increases, resulting in low heat transfer coefficients.

[0005] In view of the above problems, the present invention provides a new solar water heater, thereby solving the problem of low heat transfer coefficient in the case of solar heat absorption and heat transfer
