Thermosyphon cooling apparatus with isolation of cooled components
First Claim
1. An apparatus comprising:
- an enclosure;
a cooling system comprising;
at least three evaporators disposed in the enclosure and having respective surfaces configured for mounting of a power electronic device thereon, the evaporators fluidically coupled in series by respective electrically insulating couplers between adjacent ones of the evaporators;
a condenser positioned in and/or external to the enclosure;
at least two electrically insulating conduits coupling the evaporators and the condenser in a thermosyphon loop; and
a dielectric coolant contained in the thermosyphon loop.

Abstract
An apparatus includes at least one evaporator having a surface configured for mounting of a power electronic device thereon, a condenser fluidically coupled to the at least one evaporator by at least two coolant conduits that electrically insulate the at least one evaporator from the condenser, and a dielectric coolant contained in a thermosyphon loop comprising the at least one evaporator, the condenser and the at least two coolant conduits. The at least one evaporator may include at least two evaporators fluidically coupled by at least one coupler that electrically insulates the at least two evaporators from one another. The at least one evaporator may be housed within an enclosure, and the condenser may be positioned within the enclosure or outside of the enclosure.
