ACT’s power electronics coolers use a loop thermosyphon to move large amounts of waste heat at low thermal resistances. Heat generated by power electronics causes liquid within the attached cold plates to evaporate. The expansion of this fluid as it changes phase from liquid to vapor creates a stirring motion that increases convection and subsequently, heat transfer efficiency. The same expansion of vapor in the evaporator, combined with the condensation of liquid in the condenser, generates a gravitational pressure imbalance that naturally maintains fluid circulation between the condenser and evaporator. A substantial amount of waste heat is transferred using this natural circulation since the latent heat of evaporation of the working fluid is large. The result is an extremely high performance cold plate that requires no moving parts.
