A method of manufacturing an energy exchanging device

An energy exchanging device, the device comprising:

• an energy exchanging core, comprising:
• a plurality of plates, each defined with a plurality of through slots in a major surface by a through cut machining process, wherein each of the plurality of through slot defines a flow channel;
• and
• at least one blanking member, positioned at both the major surfaces of the plurality of plates to form a plurality of fluid flow paths about the plurality of through slots, wherein the at least one blanking member is bonded with the major surface of each of the plurality of plates, to form an energy exchanging core;
• wherein at least two inlet ports and at least two outlet ports are defined in the energy exchanging core by selectively machining portions of the at least one blanking member and the plurality of plates, for flow of fluid along the plurality of fluid flow paths within the energy exchanging core;
• and
• at least one manifold fluidically connected to each of the at least two inlet ports and to each of the at least two outlet ports to circulate the fluid through the energy exchanging core.
