Form high temperature air.This heating means are primarily present following defect: the thermal efficiency is low: because after vacuum tube heat absorbing first by the sky in pipe
Gas heats, and the cold air in the hot-air and heat collector inner container of vacuum tube exchanges heat, and hot-air is then exported from liner, this
Process, which exchanges heat, depends merely on the convection current of hot and cold air, since vacuum length of tube (1.8 meters -2.1 meters) is longer, in the hot-air pole of middle end
Endless loop easy to form cannot transfer heat away from coming, to cause system thermal efficiency relatively low, while heat convection will replace
The heat inside vacuum tube needs certain time out, this results in air heat-collecting system, and from opening heat, outflow needs centainly
Time, it is slow that system starts speed.

There are gap between cylinder and inner cylinder, the air outlet of the air supply device is connected with inner cylinder by pipeline, is opened up on the inner cylinder
There are multiple cold air outlets being arranged at equal intervals, pipe of collaborating is installed in cold air outlet, the pipe of collaborating is fixedly connected with inner cylinder, described outer
Multiple hot-air mouths corresponding with cold air outlet position are offered on cylinder, vacuum tube, the vacuum tube fixed peace are installed on hot-air mouth
On outer cylinder, the vacuum tube and pipe coaxial arrangement of collaborating, the pipe of collaborating is located inside vacuum tube and the end for pipe of collaborating
Extend to vacuum tube end position.
Further, the insulating layer is layer of polyurethane, and the wall thickness of the insulating layer is 30mm.
Further, the diameter of the cold air outlet is 36mm, and the diameter of the hot-air mouth is 63mm.
Further, the spacing of the tube end apart from vacuum bottom of the tube of collaborating is 20mm.
Further, the air supply device is blower.
Further, the inner diameter of steel flue is 120mm, outer barrel diameter 200mm.
Using above-mentioned technical proposal, the utility model has the following beneficial effects: the air heat-collecting device by hot and cold air every
From the flowing of hot and cold air is all unidirectional, reduction cold-hot air convection, so that the output temperature of delivery outlet is improved, due to adopting
With string air pipe structure, cold air is sent directly into vacuum bottom of the tube, can effectively bring out the heat inside vacuum tube, thus
Vacuum tube heat collection function efficiency is improved, while the flowing of hot and cold air is faster than Natural Circulation using forced circulation speed, system is opened
It is fast to go out hot wind speed afterwards.
Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1, inner cylinder；2, outer cylinder；3, insulating layer；4, it collaborates pipe；5, vacuum tube.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of solar energy air heat-collecting device, including heat collector header, vacuum tube 5 and air supply device,
The heat collector header includes the outer cylinder 2 and inner cylinder 1 being coaxially arranged, and the outside of the outer cylinder 2 is provided with to play insulation effect
Insulating layer 3, there are gap between the outer cylinder 2 and inner cylinder 1, the air outlet of the air supply device passes through pipeline and 1 phase of inner cylinder
It connects, offers multiple cold air outlets being arranged at equal intervals on the inner cylinder 1, pipe 4 of collaborating is installed in cold air outlet, wherein collaborate
