Abstract: A heat exchanger comprising a body provided with a plurality of compartments including at least two end compartments, each compartment defining an internal volume inside which a fluid is capable of flowing, each compartment comprising at least one opening through which a fluid passes to enter or exit said internal volume, is disclosed. The heat exchanger further comprises a separating wall disposed between two adjacent compartments and separating the internal volumes from one another, a closing wall arranged on each of the two end compartments and intended to close the internal end volume of the end compartments, and a plurality of spacers arranged inside the compartments and along the openings, the spacers being capable of maintaining a distance between two adjacent separating walls and/or the spacers being capable of maintaining a distance between the closing wall and the separating wall adjacent to the closing wall.

Abstract: Heat exchanger (1) comprising:-a body (3) provided with a plurality of compartments (10) in which a fluid is capable of flowing, and at least one sealed compartment (11), and-separating walls (5) disposed between the compartments (10, 11) and intended to hermetically separate the compartments (10, 11) from one another,-at least one dispensing or collection head (9) for distributing a fluid into the compartments (10) or for collecting the fluid exiting said compartments (10), in which heat exchanger (1) the dispensing or collection head (9) is secured to the body (3) by a welding operation and wherein said at least one sealed compartment (11) is capable of deformation following the welding operation.

Abstract: Heat exchange assembly comprising at least one first and one second heat exchange body (5, 7), each body being of the plate heat exchanger type, comprising a plurality of metal plates of substantially similar contour extending along a first dimension or length and a second dimension or width, spaced from and arranged in parallel rows to one another along a third dimension or thickness and sealing means bounding flattened passages with the said plates, forming at least one passage of a first type and at least one passage of a second type, the sealing means allocated to each passage releasing one fluid inlet and one fluid outlet, characterized in that one side bounded by a width and a thickness of at least one first heat exchange body is located at least partially opposite a side bounded by a width and a thickness of at least one second heat exchange body, the two sides being separated by insulating material (I).

Abstract: The invention concerns a louvered fin comprising an assembly of wave stems (123) alternately linked by a wave crest (121) and a wave base (122), and wherein the wave stems (123) are provided with flaps (125) cut out in said wave stems (123) and sloping at angle relative to the main undulating direction (D1). The wave stems (123), crests (121) and bases (122) form, in cross-section relative to the main undulating direction (D1), rectilinear segments, the crests and the bases being mutually parallel.
