Problems solved by technology

Most of the commonly used solar heat absorbing devices use a tubular heat absorbing layer. This structure has a small heat absorbing area, and cannot efficiently convert the absorbed solar energy into heat energy for a long time, and dissipates heat quickly, making it difficult to preserve the collected solar energy. The cost is also high; therefore, a flat heat absorbing device has appeared on the market, which has the advantages of large heat absorbing area and low cost, but it also has the disadvantage of not being able to keep warm when used, and it is easy to be cracked or damaged in freezing areas , so that its service life is greatly reduced
In addition, the above-mentioned and existing solar heat absorbing devices are only used as heat-collecting carriers to heat water, and the application range is very small.

Embodiment Construction

[0015] Such as figure 1 ,figure 2, image 3 As shown, the solar heat absorbing panel of the present invention includes a panel body 1, and the cross-sectional geometric shape of the panel body 1 is corrugated, which greatly increases the effective heat absorption area of ​​the panel body, and also increases the strength of the entire panel body 1, making it difficult to deform Damaged; air intake holes 3 are evenly arranged on the boundary line of two adjacent tiles 2 of the board body 1, which are used to accelerate the rising speed of the air during work, so that the indoor temperature rises rapidly; the board body 1 The upper surface is coated with a multi-layer gradient selective absorption film by magnetron sputtering, which improves the heat collection rate, reduces heat loss, and prolongs the service life of the plate to a certain extent. The plate body in this embodiment is a metal plate with anti-corrosion and heat conduction.

Abstract

The invention relates to a solar energy absorption plate, which comprises a plate body. The section of the plate body is corrugated; the plate body is provided with an air inlet hole; and the surface of the plate body is coated with a heat absorption membrane. Because the geometrical shape of the section of the plate body of the solar energy absorption plate is of an corrugated shape, the effective heat absorption area of the plate body is increased; the strength of the integral plate body is increased at the same time; and the plate body is not easy to be transformed or damaged; the air inlet hole arranged on the plate body is used for accelerating rising velocity of air at work, so as to raise temperature quickly; the solar energy absorption rate of the multilayer gradient selective absorption membrane coated on the upper surface of the plate body by a magnetron sputtering technique reaches more than 93 percent, so that heat collecting efficiency is higher; thermal radiation ratio is lower than 6 percent, and the heat loss is less; moreover, the heat absorption membrane layer coated on the upper surface of the plate body is not easy to age and peeled off, and prolongs service life of the integral plate body to a certain extent.

Description

technical field [0001] The invention relates to a solar heat absorbing device, in particular to a solar heat absorbing plate for increasing indoor temperature by heating air. Background technique [0002] With the rapid economic development, energy shortage has become a bottleneck restricting the economic development of various countries. As a clean, environmentally friendly and efficient energy source, solar energy is favored by countries all over the world because it is an inexhaustible source of energy. Most of the commonly used solar heat absorbing devices use a tubular heat absorbing layer. This structure has a small heat absorbing area, and cannot efficiently convert the absorbed solar energy into heat energy for a long time, and dissipates heat quickly, making it difficult to preserve the collected solar energy. The cost is also high; therefore, a flat heat absorbing device has appeared on the market, which has the advantages of large heat absorbing area and low cost...
