The wall plate part for each of the channels has a shape in which the wall plate part is bent left and right in a serpentine shape and projected and recessed parts thereof are alternately repeated and formed, and the recessed part of the wall plate part is formed with a chevron-shaped part made up of an upward slope part that ranges from a base part to the top part and a downward slope part that passes downward from the top part to a neighboring base part.

A forward-tilting protruding piece leans forward toward an upstream side in a gas flow direction. A rearward-tilting protruding piece is disposed downstream of the forward-tilting protruding piece and leans rearward toward a downstream side in the gas flow direction. The forward-tilting protruding piece is in a shape of a four- or more-sided polygon including a base side in contact with a peripheral surface of the gas passage and a pair of left and right sides. The base side is oriented obliquely with respect to a direction perpendicular to the gas flow direction. The angle of one of the sides which is located on the upstream side in the gas flow direction with respect to the base side is larger than the angle of the other of the sides which is located on the downstream side in the gas flow direction with respect to the base side.

A fuel reformer cooler for cooling a hydrogen-containing effluent released from a fuel reformer is disclosed. The fuel reformer cooler may comprise a heat transfer wall separating an effluent conduit from a coolant conduit and permitting heat transfer from the effluent in the effluent conduit to a coolant in the coolant conduit therethrough. The heat transfer wall may be formed from a base that includes a first surface facing the coolant conduit and a second surface facing the effluent conduit. The cooler may further comprise an anti-hydrogen embrittlement layer applied to the second surface of the base to shield the base from exposure to the effluent, and a plurality of symmetrical fins each extending through the anti-hydrogen embrittlement layer and contacting the second surface of the base. The plurality of symmetrical fins may project into the effluent conduit.

A heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed in accordance with an embodiment of the present invention. The heat exchanger includes a first manifold, a second manifold, a bundle of heat exchange elements and a housing. The bundle of heat exchange elements for the first fluid axially extend and provide a fluidal communication between the manifolds. The housing for the second fluid encapsulates at least part of the heat exchange elements to form a fluid tight channel for the second fluid. The housing further includes at least one sacrificial component being of material having lower galvanic potential than the remaining components.

In a method for producing a thermal component (1, 1) a pipe (2, 2,2) having a fluid channel (3, 3, 3) with an inner profile (4, 4) is provided, and a swirler (6, 6) having an outer profile (5, 5) corresponding to the inner profile (4, 4) is inserted into the fluid channel (3, 3, 3). A thermal component (1, 1) manufactured in this manner includes a pipe (2, 2, 2) having a fluid channel (3, 3, 3), and a swirler. The fluid channel (3, 3, 3) of the pipe (2, 2, 2) includes an inner profile (4, 4) corresponding to an outer profile (5, 5) of the swirler (6, 6), and the swirler is disposed in the fluid channel (3, 3, 3).

A hybrid intercooler system is provided and includes an air cooler that is configured to exchange heat with exterior air passing through an outer wall of a plurality of compressed intake air paths to cool a compressed intake air passing through the inside of the compressed intake air paths. Further, a water cooler is configured to exchange heat between a water cooler coolant enclosing the outer wall of the compressed intake air paths and the compressed intake air which is cooled in the air cooler. The water cooler includes a water cooler coolant tank that encloses the compressed intake air paths.

A transduct segment, that can include a main tube extending from a first end to a second end and defining a hollow passageway therethrough, a lower platform attached to an outer surface of the main tube on first side of an aperture defined within the main tube, and an upper platform attached to the outer surface of the main tube on second side of the aperture that is opposite of the first side, is provided. The upper platform is integral with the lower platform to define a supply channel therebetween, and the supply channel is in fluid communication with the hollow passageway of the main tube through the aperture defined by the main tube.
