Evacuated Tube Solar Collector
Heat pipes act as a low-resistance thermal conductor with a heat transfer rate thousands of times greater than solid conductors. The evacuated tube solar collector employs an evaporating-condensing cycle to capture heat and release energy to the process water.
Technical Specifications
Product Overview
High-Efficiency Thermal Solution
This advanced evacuated tube solar collector utilizes a high-performance heat pipe and vacuum-sealed borosilicate glass to maximize solar energy capture. By employing an evaporating-condensing cycle, it achieves thermal conductivity rates significantly higher than traditional solid conductors. The system is designed for durability and efficiency, featuring an aluminum-nitride selective coating and a barium getter to maintain vacuum integrity for a 15-year service life.
