Quick Request

Thermosiphons offer more cost-efficient two phase cooling than heat pipes or vapor chambers, but as they are wickless, they need a consistent gravitational pull to operate. For additional cost savings, Boyd offers advanced engineering and streamlined manufacturing that enables one shot brazing. Boyd has also developed loop thermosiphon solutions that offer passive liquid cooling for more reliable high-power cooling.


Thermosiphon Heat Exchangers

By integrating thermosiphon technology into heat exchangers, Boyd enables cost and weight savings by negating the use of a wicking structure. By utilizing gravity for reliable passive two-phase cooling, Boyd enhances heat exchangers for improved thermal transfer.



Thermosiphon Heat Transport Assemblies

Thermosiphons can work as efficient, cost saving heat pipes as they function very similarly but have no wicking structure. If they are designed properly to utilize gravity for the evaporation cycle of the two-phase cooling loop, engineers can negate the need for materials and assembly costs associated with manufacturing a wicking structure.



Thermosiphon/Two-Phase fins

By designing and manufacturing thermosiphons in a more planar geometry they can be used as fins for a bonded heat sink or even a thermally integrated enclosure. Although they do not offer as much design flexibility as vapor chamber fins, they can offer improved performance in compact systems.
