A plate heat exchanger, which includes a flexible structure and/or a heating channel between the first support end plate of the plate pack and the first end plate of the outer casing, and/or an inner tube arranged inside the inlet connection tube of the first heat exchange medium for improving plate heat exchanger's ability to withstand thermal stresses caused by temperature differences, e.g. when using in heating of liquefied natural gas.

Plate heat exchanger and its use as liquefied natural gas vaporizer

A device for use in a refrigeration or heat pump system. A device includes an outer casing which includes a longitudinal cylindrical shell and end plates arranged at both ends of the shell, and at least three units of the refrigeration or heat pump system arranged inside the same common outer casing, which units are selected from the group consisting of an evaporator, a superheater, an economizer, a condenser, a desuperheater, a sub-cooler and an oil cooler.
