Enclosed within each vacuum tube lies a precision-engineered U pipe, facilitating an efficient direct flow-through system that seamlessly connects to the
header pipe within the manifold. This meticulously designed U pipe is skillfully seamed into an aluminum heat transfer fin, residing within the
interior of the vacuum tube. This configuration effectively channels the absorbed heat from the inner tube directly to the U pipe, ensuring maximum efficiency.
Solar radiation gracefully penetrates the outer glass tube, reaching the inner sanctum where it is captured by the highly selective sputter layer on the outer surface of the inner glass tube.
This captured solar energy is then expertly transmitted to the flush-contact
aluminum shield, which subsequently directs it to the copper pipe filled with a high-performance heat transfer fluid. The encompassing 360° aluminum heat
transfer fin guarantees the swiftest and most effective energy transfer available.
