Our drop-in heat exchangers remove waste heat from sealed electrical panels and enclosures using Noren’s specially designed heat pipe core technology. Our design dissipates heat from sensitive electronic components to the ambient air outside of the enclosure without exposing them to the harsh and dirty environment outside the cabinet. This enables the heat exchanger to lower the internal temperature of the enclosure, while also keeping an air tight seal.
These drop-in heat exchangers are designed to attach to the top of electrical enclosures. The units occupy space both inside and outside of the enclosure and are ideal for applications where the top of the enclosure has enough internal and external clearance for both ends of the unit.
Our drop-in heat exchangers are available in UL Type 12, 3R, 4, and 4X. The UL Type depends on many factors. We recommend talking to our Thermal Management team in order to find the best unit(s) for your application.
Not every application requires a UL certified unit though. For these applications, we have many heat exchangers that have not been UL tested, but still do an excellent job of removing waste heat from electrical enclosures.
Custom Design Heat ExchangersDepending on your unique application, you may need a specially designed heat exchanger. Our engineering team is happy to work with you to design and manufacture a custom unit, or multiple units. Custom heat exchangers are often based on our standard heat exchangers. The various attributes of the standard unit are then modified or changed in order to meet the needs of the application. Contact our Thermal Management team for more information.

Designed to cool overheating electrical panels and enclosures to below the outside ambient air temperature, our below ambient heat exchangers easily replace air conditioners and compressed air coolers. Using a specially designed open loop core, these units remove waste heat from the cabinet and cool the internal air to the temperature of the water (also below ambient temperature) circulating through the heat exchanger’s core, using only 4 l/min water source for most units. These below ambient cooling heat exchangers are easy to install and maintain. They feature isoloss gaskets that seal against the enclosure and keep contaminants out. Below ambient cooling units are typically mounted on the side of the enclosure and can be used in series as needed. With our UL LISTED 12, 4 or 4x units, they lend themselves well to being used in 508a applications. Heat exchanger designed to be mounted to the outside of the enclosure. It can be mounted upright to the sides and does not have any components that protrude inside of the enclosure other than the power cord. It requires a 1 gallon per minute water source to properly cool the enclosure.
Flat, Bent, Finned or Embedded; Thermal Conductivity 5,000-200,000 W/m•K; Heat Transfer Over Relatively Long Distances; Long Life; No Maintenance
Noren’s unique technology and design process allow to create customized heat pipe systems with intricate bends, angles and flatness. Long life and no maintenance are added benefits of Noren’s heat pipe designs and assemblies
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, Noren’s custom heat pipes and heat sinks are designed to optimize the thermal management capabilities of virtually any application.
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. As 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 aluminium, 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).
To better solve your thermal removal requirements, Noren’s heat pipes offer the unique ability to achieve different bends, planes and dimensions within designs. Noren is able to create solutions with multiple angles and planes, all while maintaining the heat transfer needed for your custom application.

Noren’s thermal pins are high-temperature heat pipes and are used in a variety of molding equipment – injection molding, blow molding, extrusion molding and thermal form molding industries.
Faster Plastic Mold Cooling: The ability to rapidly transfer heat at high volumes is essential to the molding process, and custom thermal pins give companies the capability to do so continuously and at minimal costs. The specialized heat pipes are custom-designed to fit into most common cores for injection, extrusion, rotational, and blow molding equipment. In addition to rapid heat transfer, thermal pins also provide isothermal cooling to increase yields as well as ensure optimal quality for every mold produced.
Custom-Designed Thermal Pins: Noren’s innovative thermal pin design is so simple and efficient that its cooling is advantageous for maintenance retrofits as well as OEM production applications. One thousand times more conductive than copper of the same weight, thermal pins conduct large volumes of thermal energy away from heat sources.
Noren offers different ways to use the Thermal Pin heat conductors – you can either insert the Thermal Pin into your existing core, or Noren can make your core into a thermal pin heat conductor by processing your cores at their manufacturing facility. The function of Noren’s thermal pin heat conductors is to remove heat very quickly which reduces cycle times resulting in increased yields.
Injection/Blow Molding:In small cores, thermal pins enable cooling in areas previously inaccessible to water cooling. In solid cores, you can draw heat from the plastic to the mold base or to remote water channels. Most solid core applications pay for themselves in 4 to 12 weeks. In blow molding, the hollow thermal pin heat conductor uniformly cools the end of the blow pin. Hollow thermal pin heat conductors evenly cool the necks of blow-molded bottles.
Extrusion/Rotational Molding:Because thermal pin heat conductors are virtually isothermal, not only do they transfer heat fast, they do it evenly. They eliminate hot spots which cause sink marks, pulling and spotting. Thermal pin heat conductors transfer heat from rotational and rubber molds to heat the plastic more quickly and evenly, regardless of variations in mold thickness.
