Novel solar air heat collector device with permeable trapezoid structure

Abstract

The invention relates to a novel efficient solar air heat collector device with a permeable trapezoid structure. The solar air heat collector device comprises a shell, an edge pressing section, an inner core and the like, wherein the inner core comprises a cover plate, a plurality of efficient heat-insulating layers, a permeable trapezoid heat absorption plate, a heat absorption heat pipe and a stainless steel support. The heat absorption plate has a permeable trapezoid structure, so that a heat collection area can be increased, and air entering a heat collector is disturbed to promote heat exchange between the air and the heat absorption plate; the trapezoid heat absorption plate divides a heat collection cavity into two closed heating channels along the thickness direction to extend a heating path, and by a heat absorption net structure covering the heat absorption plate, the heat exchange efficiency and the heating efficiency are improved; the heat-insulating layers comprise an aluminum foil plate, asbestos gauze, a heat-insulating plate, asbestos gauze and an outer layer plastic plate sequentially from inside to outside; the asbestos gauze is made of rock wool or mineral wool, and the heat-insulating plate is made of rigid polyurethane; and a layer of electric heating blanket is arranged between the aluminum foil plate and the asbestos gauze and is used for performing electrical heating automatically, so that the solar air heat collector device operates conveniently at night or under the adverse weather condition.

Description

technical field [0001] The present invention relates to a heat collecting device that effectively utilizes solar energy to generate, store and transport heat, in particular to a new type of trapezoidal solar air heat collector containing permeable heat absorbing panels. Medium, and a solar air collector that integrates passive solar heat generation and autonomous electric heating. Background technique [0002] Today, with the depletion of non-renewable resources, the discovery and application of the energy field is like a battlefield. How to make good use of the developed non-renewable resources is a topic we are more concerned about, but some predecessors who are at the forefront of energy development and recycling have long begun to use Attention is turning to the development and application of new energy sources, and solar energy is favored due to its low price, wide application, and abundant reserves. Solar energy is energy from celestial bodies outside the earth (mainl...

Problems solved by technology

At present, in addition to solar power generation, solar energy is the most widely used in building heating. The technologies and products mainly include passive solar house technology and solar water heaters. This is especially true for large and deep buildings such as classrooms, office buildings, conference rooms and shopping malls. Most of the solutions to this problem use solar central heating systems. Poor antifreeze performance, difficulty in anti-scaling and anti-corrosion of pipelines are common, and once the vacuum tube breaks, it will cause a large amount of hot water loss, high system operation requirements, difficult maintenance, and low reliability

However, the contact area of ​​flat-plate collectors with the sun is not large enough, resulting in insufficient heat collection, poor effect, and excessive heat loss.

Regardless of the structure, there are three disadvantages: first, the collector has a large heat dissipation area and a short heating path, resulting in a low temperature at the outlet of the collector; second, the hot air in the collector flows naturally , the cycle speed is slow, and it does not have the function of outlet temperature adjustment; third, the collector does not have the function of heat storage, and cannot work at night or under adverse weather conditions
