heat pipe vacuum tubes

heat pipe vacuum tubes: 1.A perfect combination of the vacuum tube and the heat pip; 2.High heat efficiency.

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 aluminum fins. The liquid in the heat pipe changes into vapor which rises to the condenser. The heat then passes through the heat exchange and the vapor becomes liquid, returning to the base of the heat pipe, the heat conducts to the heat transfer liquid(anti-freezing liquid or water)via 8copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.

Feature:

1. A perfect combination of the vacuum tube and the heat pipe

2. High heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorbent coating and perfect combination with high vacuum preservation.

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

4. 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 15 years.

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