Definitions
- the invention relates to a collector for solar energy and is characterized in that the water or liquid medium, which is heated at the expense of solar energy, is also used as a light-refractive agent for the purpose of concentrating the sun's rays on the absorbent layer.
- the upper chambers 21, 21 ', 21 "should have a certain lens effect, but especially since air only flows through them, which has a low refraction coefficient, they achieve the enormously greater effect produced by the collector according to the invention, in which the chambers or lenticular lines are not flowed through by water or the liquid to be heated.
- Laid-open specification No. 2,601,295 provides for the water to flow first in the outer layer 22 (FIG. 2) and then in the inner layer 23 in the opposite direction, so that the heat dissipated, ie that emitted by the black wall 24 To use heat for preheating the water flowing through the outer channel 22.
- this collector has two disadvantages: the first disadvantage is that the air chamber 25 interposed between the outer 22 and the inner 23 chamber results in a condensation of the air moisture contained on the cold walls 22, which condensation reduces the transparency of the layer 22 and reduces efficiency.
- the second disadvantage is that the chamber 22 does not as is the case with the present invention, is lens-shaped and has the ability to concentrate the light rays, but is made flat.
- the English patent 1,157,156 provides for the collector to be produced in flexible plastic material and consequently thermally compressible material, in which collector a single channel with a serpentine course (FIG. 3) is only present when the liquid does not flow through it (see FIG. 4) and assumes a lenticular shape with the walls 26, 27 only when water or the liquid to be heated flows through it.
- the patent in no way specifies that the liquid contained in the lenticular chamber 26, 27 also serves to concentrate the light rays, as is the case in the present invention.
- the collector according to the invention is designed in a first shape corresponding to FIG. 1.
- Channels increase to an average temperature of, for example, 30 to 40 degrees.
- This water is then conducted in the opposite direction, ie in the direction of the arrows 6 ', and in the inner channels 5', 5 ", 5"', in which the upper layer 0 KULVMZ is black, ie in such a way that it is brought up by the sun rays 29 Heat absorbs which sun rays concentrate in many focal lenses 30 due to the lens effect of the outer channels 1 ', 1 ", 1"' mentioned.
- the lower layer 0 YUWVW 'Z is designed to be retro-reflective or white in order to limit downward heat losses.
- the air chambers 2 ', 2 ", 2" « and 7', 7", 7 "' serve as isolation chambers.
- blackened tubes 8', 8" or black strips are introduced into the chambers on the lower cold walls of the channels 1 ', 1 ", 1"' in the said chambers 27 ', 27 "at the expense of the scattered sun rays, not the concentrated along the focal lenses 30.
- the entire collector if it is made of flexible plastic material, as shown at 6 in Fig. 10, can be flattened or rolled up.
- the channels 2 ', 2 ", 2"' and 7 ' are identical to the embodiment shown in FIG. 7 and always in accordance with the invention.
- the upper part 1 of the channel is separated from the lower part 5 by the membrane 9, which membrane is black and on which the sun's rays concentrate.
- the channel 1 is flowed through by cold water in the direction of arrow 10. so that it heats up, while the lower channel 5 in the opposite direction, i.e. is crossed in the direction of arrow 11 by the preheated water brought in by channel 1 and warms up completely by the action of the heat supplied by the sun's rays, the sun's rays being concentrated by the water contained in channel 1 and acting as a lens and striking the black surface 9.
- the serpentine-folded channel shown at 15 in FIG. 10 has a lenticular cross-section, and the water to be heated flows through.
- the outer surface 15 of the thin plastic material. or line made of semi-rigid or rigid plastic material is transparent and the bottom 12 is black.
- the wall 13 is reflective or white and the layer 14 is made of insulating material, preferably of spongy resin, in order to reduce the heat losses.
- the parallel sun rays 29 concentrate along the line 30 on the black surface 20 and increase the temperature of the liquid contained in channel 15, which is quickly brought to very high values, close to the boiling point of the water.
- the collector 18 it is provided to keep the collector 18 inclined, so that the low-temperature water flowing in through the line 31, which water flows through the lower channels 15 "of the collector 15, collects in a warmer state at the top and flows in via the line 32 reaches the highest point of the receptacle 34.
- the water therefore flows according to the principle of a heating system, due to its different density, and is easier when it is warm from the line 32, and colder, i.e. heavier if it enters line 31.
- the container 17 denotes a container arranged at the top, to which the cold water comes from the supply line 33 and is emptied via the line 16 on the bottom of the container 34.
- the container 34 may advantageously consist of the sack made of plastic material, which serves to accommodate the collector 18, if it is flexible, when it is rolled up for transport, as shown in Fig. 18.
- the collector according to the invention is extremely simpler than the known, so-called “greenhouse collectors" with the same and also with higher efficiency.
- the serpentine through which the water flows and which is firmly connected to the black plate is enclosed in an insulated, flattened box provided with one or two lids made of glass or plastic material.
- the water representing the lenses absorbs all of the heat emitted by the black surface without requiring additional insulation. This results in a very simple and light whole.
- the cost of the collector according to the invention is actually about 1/10 and its weight corresponds to about one twentieth of that of a conventional collector.

Abstract
Dans sa forme d'execution la plus simple, le collecteur est compose d'au moins une rigole, ou un canal (15') en matiere plastique flexible, semi-rigide ou rigide, en forme de serpentin plie, et parcouru par l'eau a echauffer. Ce canal presente une pellicule (15) transparente exterieure et un fond noir (12). Sur celui-ci, les rayons du soleil (29) se concentrent le long d'une ligne lumineuse (30), sous l'action d'un effet de lentille cree par l'eau (15') contenue a l'interieur du canal. La temperature de l'eau atteint des valeurs elevees, proches de la temperature d'ebullition de l'eau.
