Plate-and-shell heat exchanger and a heat transfer plate for a plate-and-shell heat exchanger

The present invention relates to a plate-and-shell heat exchanger and a heat transfer plate for a plate-and-shell heat exchanger. The heat exchanger comprises a shell and a plurality of heat transfer plates within the shell. The plates form fluidly connected first cavities for providing a first fluid flow path for a first fluid flow. The shell forms a second cavity in which the plates are arranged, and a second fluid flow path is provided for a second fluid flow, separated from the first fluid flow path by the plates. The heat exchanger comprises heat transfer plates which are formed for improving the distribution of the second fluid flow within the heat exchanger.
