Embodiment Construction

[0015] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] In the present invention, fans are connected to 3 places of the air inlet, and the medium inlet 1 and the medium outlet 2 are connected with solar heat collectors as heat sources. The serpentine elbow 6 communicates with the solar heat collector through the medium inlet 1 and the medium outlet 2, and is filled with a heat-conducting medium at 30°C. When the sun is sufficient, the medium absorbs heat and vaporizes, enters the serpentine elbow 6 from the medium inlet 1, and flows back to the solar collector through the medium outlet 2 after releasing heat and condensing. Under the action of the fan, air flows into the device from the air inlet 3, flows along the serpentine elbow 6 and absorbs heat, becomes hot air, and then blows out from the air outlet 4.

Abstract

The invention discloses a solar air heat collector. The solar air heat collector is externally connected with a solar heat collector and serves as a heat source; a low-boiling-point liquid serves as a heat conduction medium; a snake-shaped bent tube which is curve at left and right and is in layering up and down serves as a heat transfer tube; and air is heated up. Through the design, the heat of the solar heat collector can be utilized fully, and the snake-shaped bent pipe can provide sufficient heat transfer area through being bent for multiple times, so that air absorbs heat more rapidly.

Description

technical field [0001] The invention relates to the field of solar heat utilization, in particular to a solar air heat collector which uses a flat solar heat collector as a heat source and is combined with a device for heating air. Background technique [0002] The solar air collector is a solar heat collection device using air as the medium, which is very suitable for solar building heating, dehumidification, drying of industrial and agricultural materials and other fields. Compared with vacuum tube solar collectors, flat-plate solar air collectors have the advantages of simple structure, large sunlight interception area, low sealing requirements, no antifreeze, clean, fast response, etc., but there are also large heat loss and low heat collection efficiency. low-level disadvantages. How to further improve the heat collection efficiency of flat-plate solar air heat collectors has always been the goal pursued by researchers. [0003] The flat-plate solar air collector is m...
