SOLAR THERMAL ABSORBER ELEMENT

A solar thermal collector includes a solar thermal absorber element (100) which includes a cover glass (11), a direct-flow absorber (120), a fore thermoplastic sealing (h1) for attaching the cover glass and absorber to each other leaving a distance (h1) therebetween, and a fore sealed space (130), formed by the cover glass, absorber, and fore sealing. The fore space is filled up with a first low thermal conductive gas (136). The element further includes a back insulation part, a back thermoplastic sealing for attaching the insulation part and the absorber to each other leaving a distance (h2) therebetween, and a back sealed space, formed by the insulation part, absorber, and back sealing. The back space is filled up with a second low thermal conductive gas (176). The element may include a TPS-direct-flow absorber-glass element, wherein the back glass insulation part is hermetically sealed with the TPS sealing and the back space is filled with the second gas. 申请涉及种包括太阳能热吸收元件(100)的太阳能热收集器。元件包括盖玻璃(110)、直流吸收体(120
