Heat pipes are researched and developed by ENERA together with its partners using a patented method that ensures the highest quality and performance of these elements.
Our heat pipes perform well in most geographical areas, hot or cold. This was achieved by creating an anti-freeze design copper heat pipe to ensure it’s functionality in cold conditions. Temperature limitation valves inside the vacuum tube protect it from overheating. TU1 high-purity and anaerobic red copper that we use in the tube production guarantee a long life for all of our products.
The Working Principle
The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and transfer heat to the heat pipes by aluminium fins. The liquid inside the heat pipe changes into vapour which rises into 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 in the sun.
A perfect combination of the vacuum tube and the heat pipe.
- Higher heat efficiency: advanced heat transferring the style of the heat pipe, excellent selective absorption coating and perfect combination with high vacuum heat preservation.
- Wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even under cloudy day and collect heat effectively. It can work normally even at -30*C.
- Each individual tube can work independently, and the whole machine can still work if one tube is damaged. The service of the heat pipe can be longer than 15 years.
- The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace the damaged glass vacuum tube.
