Solar heat absorber with heat absorption beneficial effect

Abstract

The invention relates to a solar heat absorber with the heat absorption beneficial effect. The solar heat absorber comprises a wrinkled heat absorption plate. The turning positions of wrinkles of theheat absorption plate is sharp. The adopted heat absorption plate is wrinkled. Firstly, the heat absorption area of the heat absorption plate can be increased; secondly, the reflection space is provided. When irradiated on the heat absorption plate, sunlight is reflected on the sidewall of the heat absorption plate multiple times to absorb heat radiation energy multiple times, and the absorption amount of solar energy is effectively increased; thirdly, the excellent solar energy absorption capacity and not harm to human bodies can be ensured through the improved structure without increasing coatings; and fourthly, the manufacturing cost is relatively low without material waste. Thus, the solar heat absorber is friendly to environment and low in cost and has the heat absorption beneficial effect.

Description

technical field [0001] The invention relates to the technical field of solar energy collection equipment, and more specifically relates to a solar heat absorber with heat absorption gain effect. Background technique [0002] At present, solar energy products on the market are very common, but there are only two types of heat sinks, namely flat plate type and tube type. [0003] The working principle of the flat plate heat absorber is that the gas or liquid passes through or passes through the heat conversion system, such as Image 6 shown. The flat plate heat absorber relies on its own metal material to absorb 50% of the radiation and converts it into heat through the metal, and then paints on the metal to absorb up to 45% of the radiation. The unfavorable factors include that this kind of coating usually contains toxic substances such as chromium and carcinogens such as titanium dioxide, which is harmful to the human body after long-term use, and will become hazardous wast...

AI Technical Summary

Problems solved by technology

The unfavorable factors include that this kind of coating usually contains toxic substances such as chromium and carcinogens such as titanium dioxide, which is harmful to the human body after long-term use, and will become hazardous waste after use and is difficult to dispose of; the material consumption of flat solar heat absorbers is large ; Coating technology has high technical content, and only a small number of manufacturers have mastered this technology

The working principle of the tube absorber is that the coated glass tube system heats the axial air or water flow, but when the tube absorber obtains heat, the tube absorber only uses half of the surface, and the shaded part Half of the energy is not obtained, and the heat absorption efficiency is not high
