Abstract
A heat exchanger comprises a plurality of cells formed by a stack of alternate planar flow-guide plates (1) and heat transfer plates (2), each heat transfer plate having at least three apertures (3, 4, 6) therethrough, each aperture defining a part of a respective one of at least three fluid flow paths in the heat exchanger. Each flow-guide plate has apertures therethrough corresponding to at least two of the flow paths and a larger aperture (5, 7, 8) therethrough configured to guide fluid in the remaining flow path across the face of the heat transfer plates between which the flow-guide plate is located, each successive flow-guide plate in the stack forming part of a different flow path from the preceding one in the stack.
Claims11
A cryogenic system for the separation of electrolytically produced oxygen and hydrogen comprising a heat exchanger,
- the heat exchanger being configured for use in the cryogenic system for the separation of electrolytically produced oxygen and hydrogen, the heat exchanger being configured to exchange heat between a mixed gas stream, hydrogen, and oxygen,
- the heat exchanger comprising a plurality of cells formed by a stack of alternate planar flow-guide plates and heat transfer plates,
- each heat transfer plate having at least three apertures therethrough, each aperture defining a part of a respective one of at least three fluid flow paths in the heat exchanger,
- each flow-guide plate having apertures therethrough corresponding to at least two of the flow paths and a larger aperture therethrough configured to guide fluid in a remaining flow path across a face of the heat transfer plates between which the flow-guide plate is located,
- each successive flow-guide plate in the stack forming part of a different flow path from a preceding one in the stack.
