Product Introduction
Our parabolic trough receiver tubes are precision-engineered core components that convert concentrated sunlight into thermal energy for medium and high-temperature applications in solar thermal systems.
Our High-Performance Parabolic Trough Receiver Tubes are the core component of any efficient concentrated solar power (CSP) system. Engineered with cutting-edge technology, these tubes are designed to capture and convert intense solar radiation into usable thermal energy with maximum efficiency and unparalleled reliability. They are the critical link that transforms sunlight into the heat required to generate clean, sustainable electricity.
How It Works: The Science of Solar Concentration
Concentration: Parabolic-shaped mirrors (troughs) track the sun and concentrate its rays by up to 80 times onto the receiver tube, which is mounted along the focal line of the mirrors.
Absorption & Conversion: The receiver tube's special selective solar coating on its inner steel tube absorbs the concentrated sunlight, converting it into high-temperature heat.
Heat Transfer: This thermal energy heats a heat transfer fluid (HTF) – such as thermal oil or molten salt – flowing through the steel tube to temperatures exceeding 400°C (750°F).
Energy storage and heating: Superheated fluids are used to generate steam for heating, or stored in thermal energy storage systems for on-demand heating.
Main features
1）Advanced Selective Coating: High-performance cermet coating ensures superior solar absorptance (α ≥ 0.95) with minimal thermal emittance (ε ≤ 0.10)
2）Vacuum Insulation Technology: Maintains optimal thermal efficiency by eliminating convective heat losses
3) Robust Construction: Features durable glass-metal sealing and getter systems for long-term vacuum integrity
4) Thermal Expansion Management: Advanced bellow compensators accommodate differential thermal expansion
