Flat plate type solar air collector

Abstract

The invention discloses a flat plate type solar air collector comprising a heat collecting frame, wherein a back board is arranged at the bottom of the heat collecting frame; a transmitting cover board is arranged at the upper part of the heat collecting frame; a heat absorbing component is arranged inside the heat collecting frame between the back board and the transmitting cover board; a heating cabin is arranged between the heat absorbing component and the transmitting cover board; a dust settling cabin is arranged between the heat absorbing component and the back board; a cold air inlet is formed in the dust settling cabin; a hot air outlet is formed in the heating cabin; a fan is arranged at the cold air inlet or the hot air outlet; the heat absorbing component comprises a heat absorbing layer with a ventilate micro-pore facing the heating cabin, and a sieve plate facing the dust settling cabin. The dust settling cabin is arranged, indoor air is successively filtered by an air filter device and the sieve plate when the indoor air enters inside the heat collector, so that dust is left in the dust settling cabin. Thus, the problem of the dust on an industrial black chemical fiber carpet is thoroughly solved, so that the heat collecting efficiency of the heat collector is improved.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to a flat-plate solar air heat collector. Background technique [0002] Flat-plate solar collectors have the characteristics of simple structure, easy processing, low cost, and can be matched with buildings. Flat-plate solar collectors are divided into two categories: air type and liquid type. Compared with using liquid as the heat collecting medium, using air as the heat collecting medium has the advantages of no anti-icing, no anti-micro-leakage, light weight and low pressure, no anti-corrosion, no need to add intermediate heat exchangers, etc. Can effectively reduce the number of system components and reduce costs. Therefore, the flat-plate solar air collector has a good prospect. At present, there are many flat-plate solar air collectors. The heated air exchanges heat through the natural convection between the glass cover plate and the environment. The heat exchange efficiency is ver...

AI Technical Summary

Problems solved by technology

At present, there are many flat-plate solar air collectors. The heated air exchanges heat through the natural convection between the glass cover plate and the environment. The heat exchange efficiency is very low, and after a period of use, the heat absorbing plate coating will be damaged. The dust in the air is covered, so the heat collection efficiency is greatly reduced
