Biggest Economies Still Lagging on Renewables

 

By Coralie Tripier

 

UNITED NATIONS, Jun 11 (IPS) On the eve of the Rio+20 Summit in Brazil, the U.S.-based Natural Resources Defense Council (NRDC) released a report Monday ranking the world's biggest countries on their use of renewable energy.

Sangle Solar heat pipe series solar collector are always connected with existing heating supply device. The selective coating on the inner Cover of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by aluminium fins. The liquid in the heat pipe changes into vapour which rises to the condenser. The heat then passes through the heat exchanger and The vapour becomes liquid, returning to the base of the heat pipe. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.

Specifications:

manifold casing: anodized aluminum alloy

2. manifold header: copper

3. heat pipe: TU1 copper

4. insulation: glass fabric

5. bracket: aluminum alloy

6. evacuated tube: SU-SS-ALN/AIN

The metal heat pipe collector is made with borosilicate 3.3 transparent glass tube,its thickness 2.0mm and OD 70mm;The tube is completely evacuated and not the same as our SL-FTREG series collector. The heat efficiency of metal heat pipe in OD70mm is 1.5 times higher than that in SL-FTREG. However,they have the same principle of transferring heat.

 

The solar energy passes though the glass and is absorbed by the selective coating on the aluminum absorber, thus it becomes hot. The heat is transferred directly to the heat pipe, making the heat-transport liquid inside evaporated very fast. The evaporation steam goes up to the condenser on the top and transfer the heat to the passing fluid or pure water in header box.And then the heat will be passed to water in tank through the exchange copper coil inside.
