摘要： A number of flat tubes, flat tube heat exchangers, and methods of manufacturing both are described and illustrated. The flat tubes can be constructed of one, two, or more pieces of sheet material. A profiled insert integral with the flat tube or constructed from another sheet of material can be used to define multiple flow channels through the flat tube. The flat tubes can be constructed of relatively thin material, and can be reinforced with folds of the flat tube material and/or of an insert in areas subject to higher pressure and thermal stresses. Also, the relatively thin flat tube material can have a corrosion layer enabling the material to resist failure due to corrosion. Heat exchangers having such flat tubes connected to collection tubes are also disclosed, as are manners in which such tubes can be provided with fins.

摘要： A heat exchanger including a collecting tank having an outwardly extending flange around an edge, a tube plate having a connection edge, tubes having ends extending into openings in the tube plate, and an intermediate plate having an edge lying against the connection edge of the tube plate. The connection edges of the intermediate plate and the tube plate are both mechanically connected to the flange of the collecting tank. Pins in the corners of one of the tube plate and the intermediate plate secure the tube plate and intermediate plate together. The connection edge of the plates include protrusions bendable onto the edge flange of the collecting tank.

摘要： A process for producing tubes (1), in particular for use in heat exchangers, from at least one metallic strip on a rolling mill train, wherein the strip, on a rolling mill train, is provided with predetermined breaking points, deformed and brought together to form the tube and finally the tubes are torn off at the predetermined breaking points between two pairs of rolls having a speed difference. The process is improved, in terms of the tearing off of individual tubes, in that an areal compressive force (Ak) is applied to the tube at least at the moment of tearing off and a sufficient tearing force (Rk) is produced and transmitted to the tube to be torn off.

摘要： A flat heat exchanger tube formed of a single strip of rolled aluminum, with at least one connection between the two broad sides. The connection is generally parallel to and spaced between the narrow sides and divides the heat exchanger tube into at least two chambers, and includes two legs consisting of bent opposite edges of the aluminum strip, the legs each having a head at adjacent bends along one of the broad sides and feet adjacent the other broad side. The legs lie against each other generally at their head over no more than half of the entire spacing between the two broad sides, with the legs enclosing an angle between them of about 20° to 100° or about 45° to 75°, advantageously 60°.

摘要： An insert adapted to connect to opposite walls in a heat exchanger tube, including a corrugated sheet having alternating wave crests and wave troughs connected by wave flanks having openings therein, wherein at least some of the wave crests have a length different than the length of the wave troughs, and/or adjacent sections have different wavelength waves. Such inserts may be produced by transporting material sheets through a press, where the sheet feed rate and/or the press stroke speed may be selectively varied.
