Heat pipe

The high heat losses from press-pack, IGBT or SiC power devices can easily be conveyed outward via heat pipe cooling units. A heat pipe is a device that uses “phase change fluid” to efficiently conduct large amounts of heat between two solid surfaces. A heat pipe consists of an enclosed tube containing a liquid (methanol, water) in a vacuum. The liquid absorbs thermal energy from the heat sources and boils rising towards the condenser. Air cools the condenser section, condensing the fluid back to a liquid which travels back to the evaporator by gravity. This is a sealed self sustaining process. • High thermal performance – superior to standard air cooled products • Convection boiling resulting in instant cooling action • Easy maintenance compared to liquid cooling systems, as heat pipes are self sustained devices and require no external water pumps or tubing • Uniform temperature distribution under components • Used in Transportation, Military, or any application requiring a robust cooling solution
