Abstract
A solar thermal absorber element (100) includes a cover glass (110) and a highly selective vacuum coated roll-bond absorber (120) including heat transport tubes (126). The element further including a thermoplastic sealing (130) configured to attach the cover glass and the roll-bond absorber to each other so that there is a distance (h) between the cover glass and the roll-bond absorber, and a sealed space (134), which is formed by the cover glass, the roll-bond absorber, and the thermoplastic sealing and which is filled up with a low thermal conductive gas (136).
Claims18
A solar thermal absorber element comprising:
- a cover glass;
- and
- a highly selective vacuum coated roll-bond absorber, a distance being defined between the cover glass and the roll-bond absorber, the roll-bond absorber comprising heat transport tubes,
- wherein a thermoplastic sealing attaches the cover glass and the roll-bond absorber to each other so that a hermetically-sealed space is formed, the hermetically-sealed space being surrounded by the cover glass, the roll-bond absorber, and the thermoplastic sealing, the hermetically-sealed space being filled up with a low thermal conductive gas.
