solar collector

copper heat pipe inside to increase the heating efficiency; water can be heated no longer than 2 minutes under average sunlight

Description of solar collector:

The absorber strip is located in an evacuated and pressure proof glass tube. The heat transfer fluid flows through the absorber directly in a U-tube or in countercurrent in a tube-in-tube system. Several single tubes, serially interconnected, or tubes connected to each other via manifold, make up the solar collector.

A heat pipe collector incorporates a special fluid which begins to vaporize even at low temperatures. The steam rises in the individual heat pipes and warms up the carrier fluid in the main pipe by means of a heat exchanger. The condensed liquid then flows back into the base of the heat pipe.

Feature

1. Can be matched with any low pressure, high pressure hot water system.2. Use heat pipe for the heat conduction and can get a high heat absorption efficiency and rapid heat transfer.3. Easy plug-in design and installation.4. Corrosion-resist Aluminum manifold and frame.5. Optional 38°/45°frame can resists wind with a velocity of 36m/s.6.Can supply hot water to large amount water need.7. Economical for hotel, school, dormitory, hospital and tall high-buildings.
