CPC Heat Pipe Solar Collector, Self-temperature-limit

Evacuated heat pipe technology
● Evacuated tubes based on the thermos flask principle and consisting of two concentric glass tubes and an evacuated gap to prevent heat loss.
● Highly selective absorber layer on the inner glass tubes (AI/ALN,) which enables an optimum energy yield.
● Aluminium heat transfer plate to provide an optimum heat transfer medium system.
● Copper heat pipes transfer the extracting heat effectively.
● Rock wool insulation with an aluminium lamination in order to prevent heat loss in the manifold.
● Compression ring fitting (Ø 22 mm) for flow and return which enable a safe and easy-to-install pipework connections.
● The most common working fluid is waterfor ambient temperatures of - 30 °C to an operating temperature to 90 °C.

Heat pipes made in China
The evacuated heat pipe technology uses the maximum fraction of solar irradiation at minimum ambient temperatures of -30  °C and maximum operating temperatures to 90 °C.

Key benefits:
● High collector efficiency of medium temperature suitable for pressurized and non-pressurized solar thermal applications.
● Due to the rapid heat conductivity evacuated heat pipe collectors are suitable for solar thermal applications in cooler areas with low ambient temperatues.
● Well-known indestructibility of the evacuated heat pipe collectors according to DIN EN 12975-2.

Recommended application areas:
Hot water generation and heating support.

Product Characteristics

● Short installation times due to complete pre-assembled collectors.

● Manageable module sizes for a very high performance and a quick and easy installation.

● Highly efficient thermal insulation.

● Flow and return pipes may be filled on the left or the right side of the manifold.

● High flexibility due to the different widths and lengths of the collectors.

● Pressurized and non-pressurized operation.

● Season independent operation depending on the heat transfer medium.

● Rapid thermal conductivity.

● High energy yield and low heat loss due to the high vacuum of the evacuated tubes.

● Operating at minimum ambient temperatures of -30 °C to maximum operating temperatures of 90 °C.

● Two loop system to constantly maintain a good water quality and to ensure water on cold days due to the anti-freezing medium in the solar circulation loop and an easy integration of other energy supplies.

The CPC heat pipe solar collector resolves the overheating issue, with self-temperautre limit of 100℃.

The collector is suitable for the cold area, could operate at mimimum ambient temperature of -35℃。

The condensing end is of 24mm, instead of 14mm, inserted into the 38mm horizontal copper pipe, for better heat transfer efficency and higher energy yield.
