Abstract

The invention discloses a solar air panel medium temperature heat collector adopting porous ceramic as heat absorbers. The solar air panel medium temperature heat collector comprises a frame, porous ceramic heat absorbers arranged in the frame, and a transparent cover plate arranged above the porous ceramic heat absorbers, wherein air runners for air circulation are formed in the porous ceramic heat absorbers; and a plurality of blind holes are formed in the surfaces of the porous ceramic heat absorbers. According to the solar air panel medium temperature heat collector, temperature fluctuation of an outlet of the air heat collector is low, and efficiency and temperature stability problems of a conventional air solar heat collector are solved; the porous ceramic heat absorbers are full-ceramic products, and the service life of the heat collector is prolonged; density of ceramic is large, thickness is large, the porous ceramic heat absorbers and air heat transfer media cooperate to inhibit temperature fluctuation of outlet air, inhibition of temperature fluctuation is determined by heat-absorbing materials, and additional materials are not required; and the heat collector is simplein structure and is easy to manufacture and mount, and the problem that the solar air heat collector is hard to popularize and apply in the field of medium temperature industry can be solved.

Description

technical field [0001] The invention relates to a heat collector, more specifically, relates to a solar air flat plate medium temperature heat collector with porous ceramics as a heat absorber. Background technique [0002] The ordinary interlayer air flat plate collector has certain value in the heating process due to its low flow resistance, but because the air collector is not under pressure, the steel plate of the flow channel is thin, and the temperature of the outlet air changes greatly when the solar radiation changes , and the performance of the surface coating of the collector is easy to decay at high temperature, which seriously affects the working efficiency of the collector. In addition, the air density is low and the heat transfer coefficient is low, so the use of air collectors is limited, and it is basically useless for use at medium temperatures above 100 °C. [0003] Current solar air collector technologies are as follows: [0004] The Chinese utility mode...
