Abstract: The invention relates to a plate-type heat exchanger for drying a gaseous medium, especially air, comprising a stack of plates which are interconnected to define flow spaces between the plates, a gas-gas heat exchanger being formed in one portion of the stack, with a moist inlet gas stream flowing away from an inlet gas connection and a dried outlet gas stream flowing towards an outlet gas connection, both flowing next to each other through separate flow spaces to exchange thermal energy, and a gas-coolant heat exchanger being formed in another portion of the stack, with a coolant and the moist inlet gas stream flowing next to each other through further separate flow spaces for cooling purposes, and a flow connection being formed between an outlet of the gas-coolant heat exchanger and the gas-gas heat exchanger, in-cluding an overflow member to guide the dried outlet gas stream through the overflow member from the gas-coolant heat exchanger to the gas-gas heat exchanger The overflow member is formed of a stac

Abstract: The invention relates to a plate-type heat exchanger comprising a stack of double-walled heat exchanger plates (30–32) which are permanently interconnected and each include two plate members (33, 34) having a central heat transfer portion (35) and an edge portion (36) bent upwardly with respect to the plane of the central heat transfer portion (35), separate flow passage spaces for at least two heat exchange fluids being defined between the double-walled heat exchanger plates (30–32), the two plate members (33, 34) entering into close mutual engagement at least partly in the area of the central heat transfer portion (35) and the upwardly bent edge portion (36) yet permitting heat exchange fluid between the plate members which gets to the upwardly bent edge portions (36) to exit through an aperture between the upwardly bent edge portions (36), the upwardly bent edge portions (36) being formed respectively with an outer edge (33a, 34a).

Abstract: The invention relates to a plate-type heat exchanger (20) comprising a stack (21) of heat exchanger plates which are permanently interconnected and between which separate flow passage spaces are defined for at least two heat exchange fluids. One part of the heat exchanger plates is designed as single-walled heat exchanger plates each, having one plate member, while another part of the heat exchanger plates is designed as double-walled heat exchanger plates each, having two plate members.
