Within every ingeniously designed vacuum tube lies a U pipe, facilitating a seamless direct flow-through. This U pipe is meticulously connected to the
header pipe nestled within the manifold, ensuring synchronized functionality. The U pipe is enveloped in an aluminum heat transfer fin, enhancing
the precision of heat transmission from the vacuum tube's interior to the U pipe, maximizing efficiency.
Solar radiation effortlessly penetrates the robust outer glass tube and is adeptly captured on the exterior of the inner glass tube by
a highly refined selective sputter layer. This captured solar energy is then transferred to a flush-contact
aluminum shield, proceeding to a copper pipe that is imbued with a high-performance heat transfer fluid. The 360° aluminum heat
transfer fin guarantees unparalleled energy transfer speed, ensuring optimal performance.
