1. A method of dissipating heat from a heat source to maintain said heat source within an operational temperature range, said method comprising the step of:

  • providing a coolant mixture within a hermetically sealed chamber, said coolant mixture comprising a first coolant with a boiling point below said temperature range and a second coolant with a boiling point above said temperature range;

    thermally coupling said sealed chamber with said heat source;

    providing a plurality of condenser chambers each coupled to said sealed chamber wherein each of said condenser chambers contains a mesh structure;

    boiling said first coolant to provide energy to circulate and agitate said second coolant;

    transferring heat from said second coolant to said sealed chamber, wherein said second coolant promotes heat transfer;

    electing said second coolant from said sealed chamber into said plurality of condenser chambers through individual inlet holes coupling each condenser chamber to said sealed chamber;

    reflowing said second coolant from said plurality of condenser chambers back to said sealed chamber using said mesh structure; and

    radiating heat from outer surfaces of said sealed chamber.
