Description

A solar air collector

technical field

The utility model belongs to the field of solar energy utilization, in particular to a solar air heat collector which can be integrated with buildings.

technical background

At present, in terms of solar thermal utilization, all-glass vacuum tubes are mainly used to provide domestic hot water for people, while solar air collectors for air heating are rarely used. The current air collectors are mostly unit flow channels and fins. When the air enters the heat collector, it is directly discharged from the heat collector and sent to the place where hot air is needed after only one-way heating. The time is relatively short and cannot absorb heat to the maximum, so the temperature rise of the air after one cycle is small, the heat collection rate has not been maximized, and heat collection cannot be maximized, and the heat collector has a complex structure and large flow resistance , which is not suitable for large-area application.

Utility model content

Aiming at the above-mentioned problems in the prior art, the purpose of this utility model is to provide a solar air heat collector, which can absorb heat to the greatest extent, and has a simple structure, which is convenient for combination and easy installation.

The technical solution adopted by the utility model to achieve its purpose: a solar air heat collector, comprising a thermal insulation back plate with a frame around it, and a heat collecting plate and a glass cover plate are arranged on the thermal insulation back plate. The heat collecting plate is a corrugated heat collecting plate, an inlet pipe and an air outlet pipe are arranged at the upper and lower ends of the corrugated heat collecting plate, and through holes are arranged in the air inlet pipe and the air outlet pipe, and the through holes communicate with the corrugated grooves on the back of the wave heat collecting plate. The side of the corrugated groove of the corrugated heat collecting plate is provided with through holes. The waveform of the corrugated heat collecting plate is trapezoidal wave, square wave or arc wave.

The beneficial effect of the utility model is that the heat absorption area is increased, which is beneficial to heat exchange, the heat collection rate is maximized, and the structure is simple and easy to assemble.
