Working principle of U-pipe Solar Collector
The fluid passes through the U-shaped copper pipe which inserted inside the vacuum tube (evacuated tube) and when warmed up, it returns up to the header pipe. An aluminum fin conducts heat from the entire inner surface of the evacuated tube and transfers it to the solar fluid inside the copper pipe. The
fin touch precisely to the inner glass tube and embraces tightly the U copper pipe with solar fluid.

Description U-pipe Solar Collector:
1. Use Super thermal U heat pipe
2. Be put in the countyard, roof, balcony
3. Supper conduct heat

Featuresof U-pipe Solar Collector:
1. No water runs through the vacuum tube, eradicating the decrease of heat efficiency due to water scaling
2. No water runs through the vacuum tube, eliminating the water leakage due to tube breakage or aging of silica gel ring.
3. No water runs through the vacuum tube, thus it will not be cracked in the extremely low temperature.
4. The water heater can still be in normal operation even when a single tube is damaged.
