The invention relates to a device (3) for absorbing electromagnetic radiation, in particular solar radiation. The device (3) has at least one flexible film pocket (4) that is divided into chambers (15). Said chambers (15) are connected to at least one feed element (5) and at least one discharge element (6), by means of which a heat transfer medium can be fed to and discharged from the chambers (15). To prevent a build-up of pressure in the heat transfer medium caused by gravity and thus unwanted stress on the film material, at least one pressure reducing element (21) is provided between at least two of the chambers (15) or film pockets (4). Said pressure reducing element (21) limits the pressure of the heat transfer medium. |
