Abstract: Flow conditioner device (40), for use in a heat exchanger system (10). The flow conditioner device includes a honeycomb structure (42) and a mesh (44). The honeycomb structure is configured for rectifying an incoming gas flow (26), and is formed by walls that border channels extending in a flow direction (X) from inlet apertures at a leading surface, to respective outlet apertures at a trailing surface of the honeycomb structure. The mesh is formed by a plurality of wires that extend along further directions (Y, Z) transverse to the flow direction, and which are mutually spaced to define openings. The mesh is attached directly to the honeycomb structure and abuts the second surface, and cross-sectional areas of the openings defined along the further directions vary as a function of position along at least one of the further directions.

Abstract: A heat transfer cell includes first and second heat transfer plates which have first and second heat transfer areas, and first and second flanges bent from the first and second heat transfer areas so as to have a height difference with respect to the first and second heat transfer areas. The first and second heat transfer plates are joined into a cell body so as to be opposite to each other in a mirror image, and the cell body having a first fluid passage therein, weld lines formed along the first contacting each other and along the second flanges contacting each other, and external recesses formed outside the heat transfer areas for second fluid passages intersecting with the first fluid passage at a right angle.

Abstract: A wire spacer (20) for spacing two adjacent heat transfer plates (2, 4) of a plate type heat exchanger (1). The wire spacer (20) is formed by a bent wire (22) that is alternatingly abutting the two adjacent heat transfer plates (2, 4), while extending along the fluid channel (6, 8) of the heat exchanger (1). The wire spacer (20) has first and second support segments (24, 26) providing a plate supporting function, and spacing segments (28) for maintaining a minimal vertical spacing (?y) between the heat transfer plates (2, 4) during heat exchanger operation. The first lower support segments (24) are formed by wire paths (32) that span a plane (S1) coinciding with a top surface of the lower heat transfer plate (2), and allow the wire spacer (20) to keep its orientation fixed with respect to the heat transfer plates.

The heat exchanger assembly (104) has a stack of heat exchanger plates (112) and a pair of outer heat exchanger plates (114) located on opposing sides of the heat exchanger assembly (104). At least one outer heat exchanger plate (114) is mechanically connected to an adjacent end panel (106) and has an outer main surface portion (122) facing the adjacent end panel (106) that is thermally connected to an end panel contacting region (125) of the adjacent end panel (106). The in-plane thermal expansion properties of the outer main surface portion (122) are identical to in-plane thermal expansion properties of the end panel contacting region (125).

Abstract: The invention relates to a heat exchanger plate (106) having first surface portions (210) located along first plate edges (220) and comprising first contacting regions (214), and second surface portions (212) located along second plate edges (222). The first surface portions (210) are bent to a first side yielding a first partial fluid channel (230), and the second surface portions (212) are bent to a second side yielding a second partial fluid channel (232). The first contacting regions (214) define a plane (S). The heat exchanger plate (106) has corner surface portions (224) comprising first corner edge portions (226) and second corner edge portions (228). At least two corner surface portions (224) are bent inward with respect to the first partial fluid channel (230) such that their first corner edge portions (226) are in the plane (S), while their second corner edge portions (228) are perpendicular to the plane (S).

Abstract: A heat exchanger apparatus (20) of the type having a rigid, unitary, parallel piped shaped core (21) mounted in a frame (22) defining support areas for the core. The core (21) is formed of a plurality of thin parallel plates (30, 30a) defining alternating passages (32, 34) for two different gas flows. Each plate (30) is connected to an adjacent plate by parallel elongated bars (31, 33) along side edges thereof, the bars being of stronger construction than the plates. The core (21) has four vertical corners, a pair of lower transverse corners and a pair of upper transverse corners. The frame (22) includes a pair of spaced parallel plates (23) and transverse structural connectors (24). Seal means (45, 46, 70) are provided both between the vertical corners (41) and the transverse corners (51) of the core (21) and the adjacent surfaces (26) of the frame defined by the pair of plates (23) and by the structural connectors (24).
