Noren - Heat Pipe

Heat pipes have an extremely effective high thermal conductivity. While solid conductors such as aluminum, copper, graphite and diamond have thermal conductivities ranging from 250 W/m•K to 1,500 W/m•K, heat pipes have effective thermal conductivities that range from 5,000 W/m•K to 200,000 W/m•K. Heat pipes transfer heat from the heat source (evaporator) to the heat sink (condenser) over relatively long distances through the latent heat of vaporization of a working fluid. Heat pipes typically have 3 sections: an evaporator section (heat input/source), adiabatic (or transport) section and a condenser section (heat output/sink).

This is the demonstration that you’ll see setup at our booth at trade shows. Folks are asked to take one of our heat pipes in their hand, then alternate stirring ice water and hot water to experience just how rapidly our heat pipes transfer thermal energy. Mr. Noren came up with this method of demonstrating the heat pipe’s performance by having clients stir their coffee with a special nickle plated heat pipe he kept in his shirt pocket. The demonstration leaves a lasting impression and often evokes a “Wow!” from the person holding the heat pipe.
