Thermosyphons are enclosed, passive two-phase heat transfer
devices. They make use of the highly efficient thermal transport
process of evaporation and condensation to maximize the thermal
conductance between a heat source and a heat sink. They are often
referred to as thermal superconductors or thermal ‘short-circuits’
because they can transfer large amounts of heat over relatively
large distances with small temperature differences between the
heat input and heat output zones. The amount of heat that can
be transported by these devices is normally several orders of magnitude
greater than pure conduction through a solid metal [1,2].
They are proven to be very effective, low cost and reliable heat
transfer devices for applications in many thermal management
and heat recovery systems. They are used in many applications
