In a compact closed two-phase thermosyphon, the boiling area isadjacent to the condensation area and the condensation area isprovided with innerfins different from conventional thermospyhons. Weclarified that the combination of condensation and self-excitedoscillation convection resulted in a good heat release. To intensitythis self-excited oscillation, we made the innerfin unsymmetrical andconsequently an improvement was realized.
