The invention relates to solar technology, in particular to inflatable solar air heaters.

An inflatable solar collector is known that contains distribution and collection collectors, tubular absorbing sections connected in parallel to them, consisting of outer transparent and inner absorbing shells.

The disadvantage of such a collector is the incomplete use of solar energy due to the uneven velocity of the blown stream over the entire surface of the absorbing sections, the occurrence of overheating zones on the absorbing shell, the complexity of the design.

The purpose of the invention is to increase the efficiency of use of solar energy and simplify the design.

The goal is achieved by the fact that in an inflatable solar air heater containing distribution and collection manifolds and heating sections connected in parallel to them, the inner absorbing shell of each of which is connected to the distribution manifold at the entrance, and the output is communicated with an outer transparent cover, the latter from the end connected to a collector collector, the distribution collector is made absorbing, tapered and coaxially installed in the collector collector, the latter is made transparent ohm, and one of the ends of the outer shell of each section is muffled,

The drawing schematically shows an inflatable solar air heater.

The heater contains a conical distribution manifold 1 with a wavy surface, a collection collector 2 and heating sections consisting of transparent shells 3 and conical absorbing shells 4 with a wavy surface.

The distribution manifold 1 communicates with the absorbing sheath 4, which in turn is output connected with

transparent sheath 3, and the last from the end connected to the collector collector 2.

One end of the transparent shell 3 is muffled. The top of the cones of the distribution manifold 1 and absorbing shells 4 is directed towards the movement of internal air flows. Distribution manifold 1 is made of absorbing and coaxially installed in the collecting manifold 2,

the latter is made transparent.

The heater works as follows.

The heater is installed on the site, accessible to the sun's rays.

Air is supplied to the distribution manifold 1. From the distribution manifold 1, air is uniformly at the same speed, since the distribution manifold is made conical to equalize the pressure losses due to air flow and losses along the length, it is distributed to the absorption shells 4 and washes them from the inside. Absorbing shells are also conical to equalize air velocity along their length. Pass the absorbing shell 4, the air enters the transparent shell 3 and washes the absorbing shell from the outside, while the direction of the air

flow is reversed. The pressure between the shells 3 and 4 is greater than the outer atmospheric pressure, but less than the pressure inside the absorbing shell 4. As a result, the stove after

Air injection is set to the working position.

The location of the distribution manifold 1 in the collecting manifold 2 and the implementation of the first of the absorbing and the second of the transparent material allows more complete use of the area occupied by the heater.

The proposed air heater design allows for a more uniform and complete volume of heat over the entire surface, while the structure itself is simple to manufacture and easy to use.
