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 arc also disclosed, as are manners in which such tubes can be provided with fins.

摘要:
The invention relates to a method for producing flat tubes from at least one strip of a continuous web material (Bb) comprising at least one wall part (a) and an undulating inner part (c), on a rolling mill that is equipped with roller pairs. The strip runs through the rollers in the longitudinal direction (LR) and is shaped, the undulating inner part (c) being introduced between the shaped wall part (a, b) and the flat tube then being closed. In order to improve the method of producing flat tubes, interspaced strip thinning lines (B) are produced which lines run in the longitudinal direction (LR) of the strip (c), and wave crests (Wb) and wave troughs (Wt) are produced that lie in the strip thinning lines (B).

The invention relates to an adhesive connection (1) for heat exchangers, particularly an adhesive connection (1) for metal flat tube ends (2), which are part of a soldered heat exchanger network (3), in corresponding openings (4) of a collection tank (5) made of plastic or metal, each opening having an annular space (6) provided around the flat tube ends (2) in which a silicone adhesive (SK) is present. In order to create a permanent adhesive connection, according to the invention the silicone adhesive (SK) is of the addition-curing type and has a low storage modulus, wherein a mounting plate (10) is provided, which delimits the annular spaces (6). In addition, the invention proposes a corresponding production method for the adhesive connection for heat exchangers and a heat exchanger.
