Heat Pipe Augmented Passive Solar Heating System

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A heat pipe augmented passive solar space heating system modulates the temperature inside a building structure, particular during heating seasons when the ambient temperature is below levels customarily associated with adequate room comfort, and in some embodiments comprises a solar absorber, a heat pipe surrounding wholly or partially by insulation, the heat pipe having three main sections which are an evaporator at one end proximal to the solar absorber, a condenser at the other end proximal to an interior room being heated, and a rubber adiabatic section between those. Additional aspects such as a mechanical valve in the adiabatic section are disclosed to limit unwanted thermal gains when cooling is needed because the ambient temperatures already exceed room comfort.
