1) Special design speed up the
exchange between light and
heat; 2) High-strength pressure-
bearining design;
Flat panel solar water heaters:
I. features: Flat Solar Collector with
pressure bearing function. The
important part is made of
blackchrome plating high quality
brass processed by special
technology after Ultraacoustic
welding. The characteristic of
this kind of solar collector is: high solar radiation heat
absorption ratio, low emissivity, high
pressure bearing ability (1 MPa
~1. 5 MPa); depending on the
climate characteristic of
European
countries and south part of
China, strict design for leakage
free structure has been
applied.
The efficiency of whole set
solar collector can reach no
lower than 50%.

III. working priciples:
The collector absorbs solar
energy and transmits it to the
water tank through
circulation. When the
temperature of the collector
reaches the set value, the
controller starts the circulation
pump automatically. The
circulation pump makes heat-
conducting liquid circulate
automatically.
