Heat Pipe Assemblies

Eco-Friendly, Customized Heat Pipes

As a two-phase, passive heat transfer solution, heat pipes are among the most common custom thermal solutions we provide. Heat pipes can be implemented for a wide variety of applications, and can be designed in any combination of bends, planes, angles, and dimensions. Whether flat, bent, finned, or embedded, our custom heat pipes and heat sinks are designed to optimize the thermal management capabilities of virtually any application.

Custom-Designed Heat Pipes

Noren’s unique technology and design process allow us to create customized heat pipe systems with intricate bends, angles, and flatness. Long life and no maintenance are added benefits of our heat pipe designs. To learn more, visit our main website by clicking here.

What is a Heat Pipe?

Heat pipes are the most common passive, capillary-driven of the two-phase systems. Two-phase heat transfer involves the liquid-vapor phase change (boiling/evaporation and condensation) of a working fluid. The heat pipe technology industry leader, Noren products has specialized in the design and development and manufacturing of passive, two-phase heat transfer devices since 1968.

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).

Standard Diameter

To better solve your thermal removal requirements, Noren’s heat pipes offer the unique ability to achieve different bends, planes and dimensions within designs.  We are able to create solutions with multiple angles and planes, all while maintaining the heat transfer needed for your custom application.

Below are the standard bend radiuses.  Noren also offers and delivers custom bending solutions.  Our experienced engineers and production team consistently produce exceptional heat transfer in various configurations.
