Abstract: A metal heat exchanger tube having integral fins formed on the tube outside and having a fin foot, fin flanks and a fin tip. The fin foot protrudes radially from the tube wall, and a channel is formed between the fins. Spaced-apart additional structures are arranged in a channel base and divide the channel between the fins into segments. The additional structures reduce the throughflow area in the channel and limit fluid flow during operation. First additional structures are radial projections emerging from the channel base and are delimited radially by an end surface located between the channel base and the fin tip. Material protrusions in the form of second additional structures lie at the location of the projections. The material protrusions are arranged between the end surface and the fin tip and lie laterally on the fin flank, and extend further axially and radially than circumferentially.

Abstract: The invention relates to a heat exchanger tube having a tube longitudinal axis, wherein fins extend continuously from the tube wall on the tube outer face and/or the tube inner face, or extend axially parallel thereto or in the form of a helix. Continuously extending primary grooves are formed between adjacent fins, said fins have at least one structured area on the tube outer face and/or tube inner face, and the structured area has a plurality of projections of a projection height projecting from the surface, the projections being separated by notches. According to the invention, a plurality of projections are deformed relative one another in pairs to such an extent that cavities are formed between adjacent projections. Furthermore, according to the invention, a plurality of projections are deformed in the direction of the tube wall such that cavities are formed between a respective projection and the tube wall.

Abstract: A heat exchanger tube with a tube axis, a tube wall, a tube outside and a tube inside. Continuously running, axially parallel or helically circling inner ribs are formed out of the tube wall on the tube inside, each inner rib having two rib flanks and a rib tip. A continuously extending groove is formed between adjacent inner ribs. The rib tip has at regular intervals recurring elevations which have an essentially frustopyramidal form. The inner ribs are raised in the radial direction on the contour line which is defined by the transitional edge of a rib flank to the rib tip and protuberances advancing out of the rib flank are formed in this region. Furthermore, the invention relates to a method for producing a heat exchanger tube.

Abstract: A metal heat exchanger tube having integral fins formed on the tube outside. The fins have a fin foot, fin flanks and a fin tip, and the fin foot protrudes radially from the tube wall. The tube includes a channel with a channel base and spaced-apart additional structures dividing the channel between the fins into segments and limiting fluid flow in the channel during operation. First additional structures are radially outwardly directed projections each with an end surface located between the channel base and the fin tip. Cavities in the form of second additional structures are disposed at the location of the projections between an end surface and the fin tip such that the cavities lie laterally on the fin flank and are open in the axial direction.

Abstract: A cooling system for the liquid immersion cooling of electronic components. The cooling system includes a container having a container wall and, in the interior, a reservoir for liquid heat transfer fluid in which positioning devices for electronic components are arranged. The container has a gas chamber for gaseous heat transfer fluid. In the gas chamber of the container, there is a heat exchanger device with heat exchanger tubes for liquefying gaseous heat transfer fluid, the heat exchanger tubes having outer fins on their outer sides. The heat exchanger tubes pass into the container wall or through the container wall at passage points. The heat exchanger tubes have an integral bond with the container wall at these passage points.

Abstract: A tube bundle heat exchanger having a tube sheet, an outer shell and an interior. The heat exchanger includes a tube bundle having tubes located in the interior for fluid flow. The tubes have outside ribs and a channel is formed between adjacent ribs. The tube sheet has openings as passage points. Outer fins of the tubes project into the openings, and a joint gap is formed between an inner surface defining the opening and the outer fins of a tube located therein. The tubes are bonded to the tube sheet by joining material with the involvement of the outer fins. The bond is only formed in a first portion of the opening. The first portion is filled with joining material such that a second portion of the opening remains which is not filled with joining material, and the tube has outer fins adjacent the second portion.

Abstract: A cooling system for the liquid immersion cooling of electronic components. The system includes a container containing, in an interior, liquid heat transfer fluid into which electronic components are immersed, the container having a gas space above the surface of the liquid heat transfer fluid, and a heat exchanger device in the gas space of the container for forming liquid heat transfer fluid. The cooling system further includes a lock device on the container for exchanging electronic components, and the lock device has a lock space, which lock space is hermetically sealed with respect to the gas space of the container to prevent gas exchange.

Abstract: A heat exchanger tube with a tube axis, a tube wall and with ribs extending around on the tube outer side. The ribs have a rib foot, rib flanks and a rib tip, wherein the rib foot projects substantially radially from the tube wall. The rib flanks are provided with additional structural elements which are arranged laterally on the rib flank. First material projections, which extend substantially in the axial and radial direction, adjoin second material projections which extend substantially in the axial and circumferential direction of the tube, wherein the first and second material projections have a common boundary line. The axial extent of the first material projections along this boundary line is less than the axial extent of the second material projections.

Abstract: The invention relates to a metal heat exchanger tube, comprising integral ribs formed on the outside of the tube. Said ribs have a rib base, rib flanks, and a rib tip. The rib base protrudes substantially radially from the tube wall. A channel is formed between the ribs, in which channel additional structures spaced apart from each other are arranged. The additional structures divide the channel between the ribs into segments. The additional structures reduce the cross-sectional area in the channel between two ribs through which flow is possible by at least 60% locally and, at least thereby, limit a fluid flow in the channel during operation.
