Solar energy air heat collector

Abstract

The invention relates to a solar air heat collector used for a heat generation device, comprising a frame which is internally provided with a heat collecting chip plate. The upper side of the frame is provided with a transparent cover plate and the lower side thereof is provided with a back plate; the solar air heat collector is characterized in that the upper side and the lower side of the heat collecting chip plate are provided with airflow passages which are communicated with each other; two ends of the airflow passages are respectively communicated with an air inlet and an air outlet; a first space is arranged between the heat collecting chip and the back plate; a second space is arranged between the heat collecting core plate and the transparent cover plate; the first space and the second space are internally provided with separation strips and steering arc-shaped separation strips which are arranged at the external end of the separation strip; one side corresponding to the steering arc-shaped separation strip is provided with a baffle which is clamped between the first space and the second space; furthermore, corresponding end sides of the baffle and the heat collecting chip plate are provided with gaps; the separation strips, the steering arc-shaped separation strips and the baffle in the first space form a loop-typed airflow passage; and the separation strips, the steering arc-shaped separation strips and the baffle in the second space form another loop-typed airflow passage. The solar air heat collector has the advantages of low cost, high efficiency and strong practicability.

Description

technical field [0001] The invention relates to a heat generating device, in particular to a solar air heat collector. Background technique [0002] In the solar air heat collector, generally only the lower side of the heat collecting core plate is connected to form an airflow channel. In Chinese patent 200620003545.9, ribs are used on the upper side of the heat collecting core board to increase the lighting area. With such a structure, the process of the heat collecting core board is more complicated, more materials are used, and the cost is high. Moreover, due to The stroke limit of the airflow channel still has the problem of low heat collection efficiency. Contents of the invention [0003] The object of the present invention is to provide a solar air heat collector with low cost and high heat collection efficiency, so as to overcome the shortcomings of high cost and low heat collection efficiency in the prior art. [0004] The solar air heat collector adopted in the...
