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 gradually heated.
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.
Applications:
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.
