Feature:

A perfect combination of the vacuum tube and the heat pipe

1. Higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorb coating and perfect combination with high vacuum heat preservation.

2. Wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even under cloudy fine day and collect heat effectively. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heat efficiency due to frost cracking or scaling.

3. Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15years.

4. The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damage glass vacuum tube.

Working principle:

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 aluminum 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 as long as the collector is heated by the sun. 

The Heat Pipes products self R/D by Suntask with 36 unique procedures and testing to ensure its excellent quality.

Use TU1 high-purity and anaerobic red copper to guarantee the life time for the heat pipe

Faster start speed and high power is the most advantage of Suntask’s heat pipes. In the same condition of testing, Suntask heat pipe quicker 30-50% on start speed and higher 30-50% temperature.
