Patent
Savo Solar Oy | Date: 2016-04-20

The invention relates to a mounting support (100) for at least one solar thermal collector (110a). The support comprising a vertical support part (120) comprising a bottom end (122) and a top end (124). The bottom end is configured to be mounted into a ground or a mounting base. The support further comprising a horizontal support part (140) configured to support the at least one collector and to enable to slide the supported at least one collector along the horizontal support part for mounting the at least one collector.

The application relates to a solar thermal collector that comprises a solar thermal absorber element (100). The element comprises a cover glass (110), a direct-flow absorber (120), a fore thermoplastic sealing (130) for attaching the cover glass and the absorber to each other so that there is a distance (h_(1)) therebetween, and a fore sealed space (134), which is formed by the cover glass, the absorber, and the fore sealing. The fore space is filled up with a first low thermal conductive gas (136). The element further comprises a back insulation part (160), a back thermoplastic sealing (170) for attaching the insulation part and the absorber to each other so that there is a distance (h_(2)) therebetween, and a back sealed space (174), which is formed by the insulation part, the absorber, and the back sealing. The back space is filled up with a second low thermal conductive gas (176). The element may comprise e.g. TPS-direct-flow absorber-glass element, wherein the back insulation part of e.g. glass is hermetically sealed with the TPS sealing and the back space is filled with the second gas.
