Abstract: A layer of a heat exchanger includes plurality of flow paths, a first end section comprising a plurality of flow path inlets and a plurality flow path outlets. a second end section comprising a turnaround section, a first morphing section fluidly connect to the first end section, a second morphing section fluidly connected to the second end section; and a central section positioned between and fluidly connected to the first and second morphing sections. The plurality of flow paths extend from the flow path inlets to the flow path outlets via the turnaround section in the second end section. In the first end section and the second end section the flow paths have a first cross section. The central section the flow paths have a second cross section and in the first and second morphing section the cross section of the flow paths morph between first and second cross sections.

Abstract: A plate fin heat exchanger comprises a circular section tubular shell. The shell comprises a plurality of first shell openings arranged along a length of the shell and a plurality of second shell openings arranged along a length of the shell. A first fluid plenum is provided on the shell in fluid communication with the first shell openings. A second fluid plenum is provided on the shell in fluid communication with the second shell openings. The heat exchanger further comprises a core extending axially within the tubular shell. The core comprises an axially extending first core passage and a second axially extending core passage isolated from the first core passage.

Abstract: A heat exchanger comprises a shell having a first inlet and a first outlet for a first fluid (H) and a second inlet and a second outlet for a second fluid (C), and a screw element. The screw element has a core and first and second nested helical flights mounted to the core. The helical flights define first and second helical fluid passages along the shell. The first fluid passage is in fluid communication with the first inlet and the first outlet and the second fluid passage is in fluid communication with the second inlet and the second outlet. The heat exchanger further comprises a plurality of tubes mounted between adjacent turns of the first and second helical flights and extending across the fluid flow passage formed between the helical flights for conducting the first and or second fluid.

Abstract: A method for forming a heat exchanger includes forming a central channel and a core section. The central channel comprises forming a channel that runs along a longitudinal axis and forming a division in the central channel such that the central channel is divided into a first section and a second section, wherein the first section is in fluid communication with a first inlet of the central channel and the second section is in fluid communication with a second inlet of the central channel.
