The utility model solves the technical scheme that its technical problem adopts: a kind of solar energy air heat collector, comprise air header and the vacuum tube of arranging perpendicular to air header axis, described vacuum tube is an end opening, the blind pipe of one end sealing, in air header, have and be arranged in parallel, cold wind runner spaced apart from each other and hot blast runner, air header is provided with the blast pipe communicating with cold wind runner and the discharge pipe communicating with hot blast runner, described vacuum tube openend is communicated with hot blast runner after being tightly connected with air header outer wall, in vacuum tube, be provided with the cooling air duct of both ends open, vacuum tube blind end is pressed close in cooling air duct one end, the cooling air duct other end is communicated with cold wind runner.

Further, described cold wind runner is positioned at hot blast runner top, and cooling air duct is tightly connected through hot blast runner and cold wind runner outer wall.

Pipeline while using for convenience connects, and described blast pipe and discharge pipe divide on the both sides end face that is located at air header.

The beneficial effects of the utility model are: the utility model by arranging cooling air duct in common vacuum tube, utilize vacuum tube to absorb solar radiation heat and thermal-arrest, the cold air displacement that hot-air is pressed into by blower fan is discharged, lengthened Air Flow length, make cold air to accept more heats and be heated intensification, adopt vacuum tube thermal-arrest, can effectively prevent from managing the convective exchange between interior hot-air and outside air, make full use of solar heat, improve Heat-collecting effect, save the energy, reduce use cost.

The specific embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of solar energy air heat collector as shown in Figure 1 and Figure 2, utilize solar radiation air heat to be applied to heating, to be dried, to dry and other hot-air application systems, the vacuum tube 2 that comprises air header 1 and absorption solar radiation heat, 30 vacuum tubes 2 are equidistantly arranged successively perpendicular to air header 1 axis, the air header 1 after assembling and vacuum tube 2 be arranged on one can more absorption solar light irradiations, have on the tilt stand of applicable setting angle.

Described vacuum tube 2 is the blind pipe of upper end open, lower end closed, in air header 1, have be arranged in parallel, cold wind runner 3 spaced apart from each other and hot blast runner 4, described cold wind runner 3 is positioned at hot blast runner 4 tops, air header 1 its right end face is connected with the blast pipe 5 communicating with cold wind runner 3, and the left end face of air header 1 is connected with the discharge pipe 6 communicating with hot blast runner 4.

The openend of described vacuum tube 2 is communicated with hot blast runner 4 after being tightly connected with air header 1 outer wall, in each vacuum tube 2, be equipped with the cooling air duct 7 of both ends open, vacuum tube 2 blind ends are pressed close in described cooling air duct 7 lower ends, and cooling air duct 7 upper ends are communicated with the inner chamber of cold wind runner 3 after being tightly connected with cold wind runner 3 outer wall through hot blast runner 4.
