Metal corrugated wire mesh type solar air heat collector

Abstract

The invention discloses a metal corrugated wire mesh type solar air heat collector. The solar air heat collector comprises a shell; a heat collecting plate and a heat preservation plate are sequentially arranged in the shell from a cover plate to a back plate; the cover plate adopts a transparent polycarbonate plate, and the outer surface of the cover plate is coated with an ultraviolet-proof layer; the heat collecting plate comprises keels and a plurality of layers of metal corrugated wire meshes supported by the keels; a top air port and a bottom air port are formed in an upper wall plate and a lower wall plate of the shell correspondingly; an upper air port and a lower air port are formed in the upper part and the lower part of the heat preservation plate correspondingly; the lower airport is connected to an air supply port of a fan through an air hose; the heat collecting plate is obliquely arranged between the cover plate and the heat preservation plate and divides a region between the cover plate and the heat preservation plate into an upper space and a lower space; and the lower space communicates with the lower air port. The solar air heat collector has the advantages thatthe heat collection area can be effectively increased, the air disturbance can be effectively enhanced by fully utilizing porous mediums of the metal wire meshes, and the heat transfer effect can beenhanced; and the solar air heat collector is suitable for rural buildings so as to improve the heating comfort of farmers in winter and meanwhile, can also be used for the operation of drying crops,wood and the like.

Description

technical field [0001] The invention relates to a heat collector, in particular to a solar air heat collector. Background technique [0002] my country has a large amount of fossil reserves and a huge amount of fossil fuels, so the environmental pollution caused by burning is also very serious. In order to reduce environmental pollution, the use of renewable energy has received more and more attention. Solar energy has received a great deal of attention as a renewable energy source. At the same time, my country has a vast land area and abundant solar energy resources. At the same time, as a clean energy source, solar energy is an environmentally friendly energy source. [0003] Among the many solar energy utilization methods, the solar air collector has the advantages of simple structure, low price, and simple manufacturing process, and has been widely recognized by the public. A solar collector is usually composed of a transparent cover, a heat collector, an insulation b...
