FAQs about Working principle of solar heat pipe
How does a solar heat pipe work?
As the gas moves to the top of the pipe, it cools and releases the heat of vaporization as it condenses back to a liquid. The liquid runs down the tube, completing the cycle. The outer tube contains a hard vacuum, so it eliminates conduction or convection loss from the gas. Figure 2 Solar Heat Pipe Construction
