Indirect plate-type heat exchanger.

摘要

The plates (7) in this heat exchanger form a first assembly of passages (8A) serving to exchange heat and a second assembly of passages (8B) which are, for at least part of their extent, connected for exchange of heat with the first assembly of passages (8A) to a reduced extent or almost not at all. The second assembly is designed to fulfil an associated function with the heat exchanger, particularly a function of storage of liquid and/or recirculation of liquid and/or the separation of liquid and vapour. Application to cryogenic heat exchangers.
