12 Tubes Aluminum Alloy Pressurized U Pipe Solar Collector For Flat
Roof Working Principle
1) Connect with pressure water tank and workstation. Water is
circulated through the header via intermittent pump cycling. Each
time the water circulates through the header, the temperatures is
raised by 5-10°C. Throughout the day, the water in the tank is
2) Solar absorption: solar radiation is absorbed by the solar tubes
and converted into heat.
3) Solar heat transfer: heat pipes conduct the heat from within the
solar tube up to the U pipe.
Domestic hot water , Solar Thermal.
Features & Advantages:
INLIGHT U pipe solar collector is a kind of pressurized and
efficient solar water heating device, heating flowing water or
liquid in closed flow passage and U pipes with glass tubes, since
the copper flow passage is welded with U pipe, water or liquid will
never flow into glass tubes. INLIGHT U pipe collector is composed
of three-target tubes, U pipe manifold and supporting bracket, and
it is commonly used in active solar water heating system.
1. It is one of the most efficient solar collector which is widely
used in active hot water heating system, supplying hot water for
domestic applications, dormitories, hotels, restaurants, schools,
hospitals, factories, swimming pools, etc.
2. The flow passage and U pipes is closed and pressurized, water or
liquid will not flows into glass vacuum tubes, no freeze expansion
or inner thermal shock to break vacuum tubes.
3. U pipe tip is welded together with copper flow passage,
withdrawal or breaking one or several glass tubes will not drain
the collector loop.
4. Aluminum alloy as manifold shell and bracket makes the collector
superior in chemical resistance, universal bracket suitable for
slope and flat roof installation.
5. Modularized collector, arbitrary combination with any
architectural structure, adaptable to slope roof or flat ground or
upright walls, maintenance free collector
6. The collector can be used in -40oC weather with anti-freezing liquid for heat conduction.
7. System efficiency: >55% in summer and >42% in winter
