What are Heat Pipes?
Heat Pipe are thermal transfer divices that are capable of transfering heat seval hundred times faster than conventional methods. Heat Pipe Structure:A traditional heat pipe is a hollow cylinder filled with a vaporizable liquid. Heat is absorbed in the evaporating section. Fluid boils to vapor phase. Heat is released from the upper part of cylinder to the environment; vapor condenses to liquid phase Liquid returns by gravity to the lower part of cylinder (evaporating section)

Using Heat Pipes to Improve Dehumidification
Heat pipes may be described as having two sections: *precool* and *reheat. The first section is located in the incoming air stream. When warm air passes over the heat pipes, the refrigerant vaporizes, carrying heat to the second section of heat pipes, placed downstream. Because some heat has been removed from the air before encountering the evaporator coil, the incoming air stream section is called the precool heat pipe.* Air passing through the evaporator coil is assisted to a lower temperature, resulting in greater condensate removal. The "overcooled" air is then reheated to a comfortable temperature by the reheat heat pipe section, using the heat transferred from the precool heat pipe. This entire process of precool and reheat is accomplished with no additional energy use. The result is an air conditioning system with the ability to remove 50 to 100% more moisture than regular systems.

Using Heat Pipes for Energy Recovery from Exhaust Air to Supply Air
Energy Recovery Heat Pipes from HPT provide economical and reliable recovery of both heat and cooling. Traditional heat pipes normally transfer heat in one direction during the heating season and the opposite direction during the cooling season, they have been equipped with a tilting mechanism. HPT has developed Heat Pipes with patented circuital loops in a 3-D (three-dimensional) configuration. The Heat Pipe fluid moves in a continuous one directional flow through the individual three-dimensional circuits. This avoids the need for a tilting mechanism.
