All-glass double -tube structure with copper heat pipe

Specifications and Product Details:

Features of our triple target coating tube with copper heat pipe:
1) High heat effectiveness: higher than all glass evacuated solar collector tube
by 15%
2) heat pipes conduction: successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand
3) Prevents the tube from being easily broken caused by volume expansion when
water freezes in the frigid season
4) Low thermal capacity makes the tube start up quickly
5) Energy output within only 2 minutes of sunshine
6) Insulation temperature can reach 250deg;C, average heat efficiency can still be
more than 50%; even under -50deg;C
7) High efficient selective absorptive coatings and vacuum heat insulation technology
ensure the tube has higher heat output in cloudy weather and in moist areas,
especially in winter
8) Solar collecting plate is sealed inside a high quality borosilicate glass tube
with 5 x 10 - 3Pa of vacuum, to stop corrosion; even in moist conditions
Metal-glass evacuated solar collector tube consists of a triple target coating tube and a
flat or curved aluminum plate inside attached to a copper heat pipe.
