3. high efficient.

Work principle

Evacuated tubes convert solar energy into heat energy, that is transferred to U pipe by an aluminum fin with high solar energy absorption and low heat radiance loss, Liquid (antifreezing liquid or water) in the U pipe heats up, and the U pipe conducts thermal energy to the water inside the storage tank directly (or through internal copper coil), With a testing pressure of 1.2 MPa, Working pressure is 0.6MPa.

Thermosyphon

In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold.

This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat from the interior tube to the U pipe.

Solar radiation permeates the outer glass tube and is captured on the outside of inner glass tube by highly selective sputter layer.

The captured solar radiation is transmitted to flush-contact aluminum shield and then copper pipe filled with heat transfer fluid.

The 360° Aluminum heat transfer fin assures the fastest energy transfer.
