Solar air heat collector device for new type penetration wavy structure

Abstract

The invention relates to an efficient solar air heat collector device for new type penetration wavy structure, comprising a shell, a blank holding profile and an inner core; the inner core comprises a cover plate, a multi-layer efficient insulation layer, a penetration wavy heat-absorbing plate, a heat-absorbing tube and a stainless steel bracket. The heat-absorbing plate is a penetration wavy structure; on one hand, the heat collecting area can be increased, the air in the heat collector can be disturbed, so as to promote the heat exchange between the air and the heat-absorbing plate; on theother hand, the heat collecting chamber in the thickness direction of the penetration wavy heat-absorbing plate is divided into two sealed heating channels, the heating path is prolonged; simultaneously, a heat-absorbing net structure covered on the heat-absorbing plate can magnify the heat exchange efficiency and improve the heat efficiency. The insulation layer comprises an aluminum foil plate,an asbestos net, an insulation plate, an asbestos net and an outer layer of plastic plate from inside to outside; the material of the asbestos net is rock wool or slag wool; the material of the insulation plate is rigid polyurethane; a layer of electric heating blanket is disposed between the aluminum foil plate and the asbestos net, which is used for electric heating independently, so that the invention can work conveniently at night or under adverse weather condition.

Description

technical field [0001] The 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 solar air heat collector with permeable heat-absorbing panels and a wave-like structure. Heat 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 ...

AI Technical Summary

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
