Abstract: A heat exchanger with a housing (3) that contains a set of channels (12); an inlet collector (4) having an inlet collector chamber (9) with an inlet (5), wherein the inlet collector chamber (9) includes first flow distribution means (10) configured to distribute a flow originating from the inlet (5) evenly over the set of channels (12); and an outlet collector (6). The first flow-rate distribution means (10) consist of a single body (15) that comprises two flow-conducting surfaces (16), which are symmetrical with respect to each other according to the first plane of symmetry and the second plane of symmetry, and which two flow-conducting surfaces (16), as seen from the inlet (5), are inclined downward in a first direction perpendicular to the first plane of symmetry and/or in a second direction perpendicular to the second plane of symmetry.

Abstract: A spacer device for incorporation into a bent-tube heat exchanger that includes a spine and a plurality of fingers that protrude from one side of the spine. The number of fingers in the spacer device is less than the number of tubes that are folded in a region to form the bent-tube heat exchanger. The plurality of fingers are configured to exert a force against the tubes and to provide and maintain a separation between the tubes in the folded region. A heat exchanger that includes the spacer device may also include a coating on the tubes in the folded region in order to reduce corrosion and increase the life-time of the heat exchanger. The method of forming the heat exchanger includes placing the spacer device between the tubes, such that the fingers lay on the tubes in the region to be folded and assist in the folding process.

Abstract: A tube body for a heat exchanger may include an outer structure composed of a band material. The outer structure may include two mutually opposite wide sides and two mutually opposite narrow sides delimiting an outer structure interior space. The tube body may further include an inner structure integrally arranged on the outer structure and composed of the band material. The inner structure may be arranged in the outer structure interior space and divide the outer structure interior space into at least two fluid ducts fluidically separated from one another through which a fluid is flowable. The band material may have a material thickness and, at least in certain portions, a material thickness of a portion of the band material defining the inner structure may be less than a material thickness of a portion of the band material defining the outer structure.

Abstract: A fin-tube type of heat exchanger has: a plurality of fins laminated to one another; a housing for containing therein the fins; and a heat transfer tube penetrating the fins in a fin-laminating direction and also penetrating side plates on both sides of the housing. A heat transfer tube through hole is formed in one-side side plate of the housing by a burred hole having a tubular flange part protruded into the housing. Each fin has a brazing material insertion hole adjacent to the heat transfer tube through hole. That portion of a brazing material which protrudes from the brazing material insertion hole of the outermost fin closest to the one-side side plate part toward the one-side side plate part gets molten. The tubular flange part has a cutout part formed, at a circumferential position facing the brazing material insertion hole, by partly cutting away the tubular flange part.
