Claim 10:
11. A vapor-to-air heat exchanger for an aircraft powerplant, comprising:
an evaporator supplying vapor; and
a condenser including:
a condenser inlet in fluid communication with the evaporator to receive vapor therefrom;
a condenser outlet; and
an array of pneumatic vessels spaced from one another in an array orientation so as to define at least one air flow path along a path orientation transverse to the array orientation, at least one pneumatic vessel of the array of pneumatic vessels defining an cavity, a plane transverse to the array orientation extending through the cavity, the cavity being in fluid communication between the condenser inlet and the condenser outlet, the at least one pneumatic vessel being inflatable when the cavity is pressurized by the vapor to transition from a collapsed vessel configuration to an inflated vessel configuration, a size of the at least one pneumatic vessel in the array orientation being greater in the inflated vessel configuration than in the collapsed vessel configuration.
