The invention relates to a metal heat exchanger tube, comprising integral fins formed on the outside of the tube and having a fin base, fin flanks, and a fin peak, wherein the fin base protrudes radially from the tube wall, and a channel having a channel bottom is formed between the fins, in which channel additional structures spaced apart from each other are arranged. The additional structures divide the channel between the fins into segments. The additional structures locally reduce the cross-sectional area through which flow can pass in the channel between two fins and at least thereby limit a fluid flow in the channel during operation. First additional structures are projections starting from the channel bottom and directed radially outward, each of which are limited in the radial direction by a terminating surface located between the channel bottom and the fin peak, thus defining a radial extension of the projections. At the location of the projections, radially outer material protrusions are arranged as second additional structures, which protrusions are formed from the material of the fin flanks. The material protrusions are each arranged between a terminating surface and the fin peak in the radial direction, such that the material protrusions are formed about the radial extension of the projections over the channel bottom of the channel, lying laterally on the fin flank. The material protrusions extend further in the axial and radial direction than in the circumferential direction.

Abstract

The invention relates to a metal heat exchanger tube, comprising integral ribs formed on the outside of the tube, said ribs having a rib foot, rib flanks, and a rib tip, the rib foot protruding radially from the tube wall and a channel being formed between the ribs, which channel has a channel bottom and in which channel there are arranged additional structures spaced apart from each other. The additional structures divide the channel between the ribs into segments. The additional structures locally reduce the cross-sectional area through which fluid can flow in the channel between two ribs and thus at least delimit a fluid flow in the channel during operation. First additional structures are delimited by radially outwardly directed projections which start from the channel bottom and are each delimited in the radial direction by a termination face located between the channel bottom and the rib foot, thus defining a radial extension of the projections. Radially outwardly located cavities are arranged as second additional structures at the location of the projections and are formed from material of the rib flanks and of the radially outwardly arranged termination face of the projections. The cavities are each arranged in the radial direction between a termination face and the rib tip, so that the cavities around the radial extent of the projections are formed above the channel bottom of the channel, laterally against the rib flank. The cavities are open in the axial direction.

Abstract

The invention relates to a metal heat exchanger tube (1), comprising integral ribs (2) formed on the outside of the tube, said ribs having a rib foot (3), rib flanks (4), and a rib tip (5), the rib foot (3) protruding radially from the tube wall (10) and a channel (6) being formed between the ribs (2), which channel has a channel bottom (61) and in which channel there are arranged additional structures (7, 71, 72) spaced apart from each other. The additional structures (7, 71, 72) divide the channel (6) between the ribs (2) into segments (8). The additional structures (7, 71, 72) locally reduce the cross-sectional area through which fluid can flow in the channel (6) between two ribs (2) and thus at least delimit a fluid flow in the channel (6) during operation. First additional structures (7, 71) are delimited by radially outwardly directed projections (71) which start from the channel bottom (61) and are each delimited in the radial direction by a termination face (713) located between the channel bottom (61) and the rib foot (5), thus defining a radial extension of the projections (71). Radially outwardly located cavities (72) are arranged as second additional structures (7, 72) at the location of the projections (71) and are formed from material of the rib flanks (4) and of the radially outwardly arranged termination face (713) of the projections (71). The cavities are each arranged in the radial direction between a termination face (713) and the rib tip (5), so that the cavities (72) around the radial extent of the projections (71) are formed above the channel bottom (61) of the channel (6), laterally against the rib flank (4). The cavities (72) are open in the axial direction.

Abstract

The invention relates to a metal heat exchanger tube (1), comprising integral fins (2) formed on the outside of the tube and having a fin base (3), fin flanks (4), and a fin peak (5), wherein the fin base (3) protrudes radially from the tube wall (10), and a channel (6) having a channel bottom (61) is formed between the fins (2), in which channel additional structures (7, 71, 72) spaced apart from each other are arranged. The additional structures (7, 71, 72) divide the channel (6) between the fins (2) into segments (8). The additional structures (7, 71, 72) locally reduce the cross-sectional area through which flow can pass in the channel (6) between two fins (2) and at least thereby limit a fluid flow in the channel (6) during operation. First additional structures (7, 71) are projections (71) starting from the channel bottom (61) and directed radially outward, each of which are limited in the radial direction by a terminating surface (713) located between the channel bottom (61) and the fin peak (5), thus defining a radial extension of the projections (71). At the location of the projections (71), radially outer material protrusions (72) are arranged as second additional structures (7, 72), which protrusions are formed from the material of the fin flanks (4). The material protrusions (72) are each arranged between a terminating surface (713) and the fin peak (5) in the radial direction, such that the material protrusions (72) are formed about the radial extension of the projections (71) over the channel bottom (61) of the channel (6), lying laterally on the fin flank (4). The material protrusions (72) extend further in the axial and radial direction than in the circumferential direction.

The lamella is machined out of the first metallic material at the surface of the first component such that it is connected monolithically to the first component in a connecting region and, starting therefrom extends as far as a free end and, when deflected out of a rest position toward the surface of the first component, exerts a spring force directed away from the surface. A second component is in immediate contact with the lamella of the first component.
