EN-12975 Heat Pipe Solar Energy Collector

EN 12975 best efficiency solar collector
(SOLAR KEY MARK,SRCC,CE)
High standard collector, hamonious with environment
Working principle for the solar collector:
The heat pipe vacuum tube absorbs the solar rays and conducts the heat to the copper pipe inside the tubes. Then the copper pipe conducts the heat from the bottom to the top end. You know the top end of copper pipe is inserted into the copper header, so copper pipe will make heat exchange with the copper header, and then when the medium fluid go through the copper header, medium fluid will be heated.
