A plate apparatus suitable for heat and/or material exchange has plates (P.sub.0, P.sub.1, P.sub.2, P.sub.3) contacting each other flush along a peripheral seal (1) while forming respective intermediate spaces (Z.sub.0, Z.sub.1, Z.sub.2, Z.sub.3) and having upper (2, 3) and lower (4, 5) through-flow openings for fluids. A group of these upper and lower through-flow openings (2, 5) is allocated to at least two fluids and is connected by correspondingly placed seals to every second plate intermediate space (Z.sub.1, Z.sub.3) carrying a flow from top to bottom. In flush upper through-flow openings (2) of plates (P.sub.0, P.sub.1, P.sub.2, P.sub.3) a distribution lance (6) runs across these openings and has outlet openings (6a) for at least one of the fluids. It is essential that the outlet openings (6a) are directed into those plate intermediate spaces (Z.sub.0, Z.sub.2) arranged between the second plate intermediate spaces (Z.sub.1, Z.sub.3) for the fluids to be mixed.

A method of manufacturing a heat exchanger array that includes stacking a plurality of heat exchanger units in an aligned configuration with respective first ports of the plurality of heat exchanger units aligned. The method can further include generating heat in the first coupling elements at the same time and at a temperature sufficient to generate a first plurality of respective couplings between adjacent sheets of adjacent heat exchanger units about adjacent first ports and without a coupling being generated between the first and second sheets of a given heat exchanger unit.

A heat exchanger comprising a plurality of plates that are demountably attached to a frame is disclosed. Each plate comprises a plurality of channels for conveying a primary fluid through the heat exchanger. The frames are arranged in the frame so that spaces between adjacent frame pairs define conduits for conveying a secondary fluid through the heat exchanger. The plates are mounted in the frame so that they can be individually removed from the frame. Further, each of the channels is fluidically connected to input and output ports for the primary fluid by detachable couplings. As a result, heat exchangers in accordance with the present invention are more easily repaired or refurbished than prior-art heat exchangers.

A plate fin heat exchanger is configured to receive hot flow from a hot source and cool flow from a cool source. The plate fin heat exchanger includes a plurality of plates arranged in parallel to define a plurality of flow passages there between, and a set of closure bars arranged at a first side of the plurality of plates to seal a first set of the flow passages against ingress of the hot flow, thereby directing the hot flow into a second set of the flow passages. Each respective closure bar includes an inner core formed of a first material having a first coefficient of thermal expansion and an outer cladding arranged about the inner core, the outer cladding formed of a second material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is less than the second coefficient of thermal expansion.
