Nestled within each vacuum tube, the U pipe features an innovative direct flow-through design seamlessly connected to the
header pipe nestled inside the manifold. This ingenious U pipe is meticulously seamed within an aluminum heat transfer fin, which is strategically positioned in the
interior of the vacuum tube, efficiently transmitting the generated heat to the U pipe for optimal thermal performance.
Solar radiation gracefully permeates the protective outer glass tube and is skillfully captured on the exterior surface of the inner glass tube by a
highly selective sputter layer. This expertly captured solar radiation is then channeled to a flush-contact
aluminum shield and onwards to a copper pipe filled with advanced heat transfer fluid. The comprehensive 360° aluminum heat
transfer fin ensures rapid and efficient energy transfer, maximizing the system's performance.
