Heat Pipe Solar Collector

Evacuated heat pipe technology

● The evacuated tubes utilize the thermos flask principle, comprising two glass tubes with an evacuated gap to prevent heat loss.

● The inner glass tubes feature a highly selective absorber layer (AI/ALN), ensuring optimal energy yield.

● An aluminium heat transfer plate facilitates an efficient heat transfer medium system.

● Copper heat pipes effectively transfer the extracted heat.

● The manifold is insulated with rock wool and an aluminium lamination to minimize heat loss.

● The flow and return connections utilize compression ring fittings (Ø 22 mm), ensuring secure and easy installation of the pipework.

● The commonly used working fluid is water, suitable for operating temperatures ranging from -30 °C 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

● The collectors are fully pre-assembled, resulting in short installation times.

● The modules have manageable sizes, allowing for high performance and quick, easy installation.

● The thermal insulation is highly efficient.

● The manifold allows for filling the flow and return pipes on either the left or right side.

● The collectors come in different widths and lengths, providing high flexibility.

● The system can operate in both pressurized and non-pressurized modes.

● The system can operate independently of the season, depending on the heat transfer medium.

● The thermal conductivity is rapid.

● The evacuated tubes have a high vacuum, resulting in a high energy yield and low heat loss.

● The system can operate in temperatures as low as -30 °C and as high as 90 °C.

● The two-loop system ensures good water quality and prevents freezing on cold days. It also allows for easy integration with other energy sources.
