Describe how evacuated heat pipe tubes (EHPTs) work.
What will be an ideal response?
A somewhat more efficient, but also more expensive type of solar collector uses evacuated heat pipe tubes (EHPTs) to transfer heat to the working fluid. EHPTs are composed of double glass tubes, one within the other, with the space between the tubes evacuated to reduce heat transfer. The inner tube of each EFPT contains an absorber plate fused to a heat pipe. The heat from the hot end of the heat pipes is transferred to the working fluid in a heat exchanger called a manifold. The manifold is insulated and encased in sheet metal or plastic to protect it from the elements.
