Description

The heat pipe solar collector consists of heat pipe glass vacuum tube, pressurized manifold, supporting bracket and other related accessories.

Working principle:

1. The heat pipe series solar collector are always connected with existing heating supply device.

2. 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.

3. The liquid in the heat pipe changes into vapor which rises to the condenser.

4. The heat then passes through the heat exchanger and the vapor becomes liquid, returning to the base of the heat pipe.

5. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe.

6. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.

Features:

1) Solar heat pipe and its inner medium for thermal conduction, with a quick start and super daily efficiency about 55% in summer and 42% in winter, much more than that of the all-glass tube

2) The flow passage is inner closed and pressurized, no water or medium goes through glass vacuum tubes, no freeze to break vacuum tubes, able to serve in extremely cold weather

3) Heat pipe tip is inserted into a closed cannel welded into the copper flow passage, collector works well even withdrawal one or several heat pipe vacuum tubes

4) Aluminum alloy as bracket with super performance in chemical resistance, universal bracket suitable for slope and flat roof installation

5) Modularized collector, arbitrary combination with any architectural structure, adaptable to either slope roof or flat ground or upright walls, almost maintenance free collector
