A method of making an end-piece for a plate heat exchanger, wherein the end-piece includes a frame part having inner and outer portions, and an intermediate portion arranged between the inner and outer portions, with the outer wall surface of the inner portion being arranged to face a first surface of a package of heat transfer plates comprising the plate heat exchanger, and the first surface having a center portion and a peripheral portion encircling the center portion. The method includes extruding the frame part with plural cavities in the intermediate portion of the frame part that extend in the extrusion direction of the frame part and that are parallel to the frame part axis, with outer dimensions of the outer wall surface of the inner portion configured to be at least as large as outer dimensions of the center portion of the first surface heat transfer plate package.

A cooling device for cooling a fluid comprises a vertical cooling tower, into an upper area of which the fluid to be cooled is fed and from a lower area of which the cooled fluid is discharged. The fluid in the cooling tower is cooled by a cooling gas flowing from the bottom to the top. At least one installation in which the fluid is conducted is provided in the gas space of the cooling tower through which cooling gas flows. Each installation comprises at least one fluid channel that is separated at least in part from the gas space of the cooling tower by a fluid-tight membrane wall that is permeable to vapor on both sides.

A vapor-to-air heat exchanger for an aircraft powerplant that includes: a pressurized vapor source supplying vapor; and a condenser including a condenser inlet in fluid communication with the pressurized vapor source to receive the vapor, a condenser outlet, and at least one pneumatic vessel defining a cavity in fluid communication between the condenser inlet and the condenser outlet. The pneumatic vessel is reversibly inflatable to be configurable between a collapsed vessel configuration and an inflated vessel configuration. A volume of the cavity is greater in the inflated vessel configuration than in the collapsed vessel configuration. The pneumatic vessel is inflatable from the collapsed vessel configuration to the inflated vessel configuration when the cavity is pressurized by the vapor.

An end-piece for a plate heat exchanger comprises a frame part having an inner portion, an outer portion and an intermediate portion arranged between the inner and outer portions. An outer wall surface of the inner portion faces a first surface of a package of heat transfer plates comprised in the plate heat exchanger. The first surface has a center portion and a peripheral portion encircling the center portion. The frame part is extruded and the intermediate portion of the frame part comprises a first number of cavities extending in an extrusion direction of the frame part. The extrusion direction is parallel to an axis of the frame part. Further, outer dimensions of the outer wall surface of the inner portion are at least as large as outer dimensions of the center portion of the first surface of the package of heat transfer plates.

A method of making and operating a heat exchanger that includes introducing a first fluid into a fluid chamber of a membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a non-flat configuration while the membrane heat exchanger is disposed within a chamber with the membrane heat exchanger extending from a first end to a second end of the chamber and generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber. The membrane heat exchanger includes sheets that form a fluid chamber.
