Detailed Product Description
BAOGUANG heat collector vacuum tube technical data:
a) This collector tube adopts magnetron sputtering coating technology
b) Sediment absorption coating (CU/SS-AL-ALN) which makes it has high absorptivity and very low emissivity.
c) Specific absorption: α≥0.93~0.96 (AM1.5)
d) Emission ratio: ε≤ 0.06 (80+5°C)
e) Glass pressure of vacuum interlayer: p≤5 x 10-3Pa
f) Radiant exposure of close bask: H=3.7-4.2MJ/sq.m
g) Average heat waste coefficient: UIt≤.90W/ (sq.m°C)
h) It can resist impact of metal ball (25mm)and could perform very well in cold area in winter.
