Three Layer Solar Evacuated Tube: high thermal efficiency, more durable for low temperature and high temperature
♦Application
Heat pipe vacuum tube consists of the glass vacuum tube and a copper heat pipe which is fixed by aluminium flake and silicon plug. they are used to transfer heat from within the evacuated tube up to the header pipe that is housed in the insulated manifold box.
♦Specifications
Axial heat flow density≥28MW/sq.m.
Equivalent thermal coefficient≥14MW/m•°C
Radiation aggregate activity αis 1.4*10-1Bq/g
Acceptable service life ≥150000h
