Controlling Wrap-Around Heat Pipe Systems for

Since the wrap-around heat pipe system is a passive device, there is no means to control the amount of reheat applied to the supply air stream. The heat pipe can only reheat with as much energy as is extracted from the air on the precool side. Therefore, if a heat pipe system is selected for a hot day, theConvection Heat Transfer Coefficient EstimationNov 12, 2020Convection heat transfer takes place whenever a fluid is in contact with a solid surface that is at a different temperature than the fluid.
