Abstract: The present disclosure relates to an engine (100) including a cylinder (102) that is filled with carbon dioxide. A first piston (104) is slidably configured inside the cylinder (102) and being configured to form a first cylinder (108) with a first end (130) of the cylinder (102). A second piston (106) is slidably configured inside the cylinder (102) and being configured to form a second cylinder (110) with a second end (132) of the cylinder (102). A heater (112) is circumferentially disposed around the first cylinder (108) and the first piston (104) is configured to expand a hot carbon dioxide received inside the first cylinder (108) from the heater (112). A cooler (116) is circumferentially disposed around the second cylinder (110) and second piston (104) is configured to compress a cold carbon dioxide received inside the second cylinder (110) from the cooler (116).

Abstract: The present disclosure discloses a method (200) of manufacturing an energy exchanging device (100). The method includes defining a plurality of through slots (14, 17) in a plurality of plates (2) by a through cut machining process, in which, each of the plurality of through slots define a flow channel. The method further includes stacking the plurality of plates (2) with at least one blanking member (24) positioned therebetween. Such stacking of the plurality of plates (2) forms a plurality of fluid flow paths about the plurality of through slots. The method further includes bonding the at least one blanking member with the plurality of plates, to form an energy exchanging core (1). The method further includes defining at least two inlet ports (45a, 45b) and at least two outlet ports (46a, 46b) in the core, for flow of fluid along the plurality of fluid flow paths within the core.
