Embodiment Construction

[0046] A schematic cross-sectional view of a refrigerant tube according to a first embodiment of the present invention is shown in FIG. 1 . The tube is generally flat and has a width w of up to 100 mm, typically about 15 to 50 mm, and a height h of up to 10 mm, typically about 0.5 to 5 mm. Prior art tubes made of non-profiled aluminum sheet have a wall thickness of 0.25 to 0.4 mm, but tubes with reinforced walls according to the invention can have thinner walls while maintaining the same stability and compressive strength , for example a=0.1 to 0.3 mm, preferably 0.15 to 0.25 mm.

[0047] The tube is made of an upper wall 2 and a lower wall 4 formed by longitudinally folding a rolled sheet metal like a hairpin. Creases are referenced at 12. On the other side, the upper and lower walls are held together by a flange 14 which, in this example, terminates around a step 15 on the lower wall, thereby creating a gap between the upper and lower walls relative to each other. Mechani...

Abstract

The present invention relates to a tube (1) made of a profile rolled metal product, in particular for use in heat exchangers, a rolled metal product and a method of producing the same. The tube (1) includes a first wall (2) and a second wall (4) forming two opposing sides of the tube, and a plurality of reinforcing structures connecting the first and second walls (2, 4) and forming longitudinal passages (10) between them. Each reinforcing structure is formed by a longitudinal ridge (6) on the first wall (2) projecting towards the second wall (4) and a longitudinal ridge (8) on the second wall (4) protecting towards the first wall (2). The ridges (6, 8) are joined to each other at their sides.

Description

technical field [0001] The present invention relates to a tube made of a profiled rolled metal product, in particular for a heat exchanger, to a rolled metal product and to a method for producing such a tube. In particular, the invention relates to a pipe comprising a plurality of reinforcement structures forming longitudinal passages between them for conveying a fluid, such as a refrigerant. Background technique [0002] Heat exchangers, such as condensers, evaporators, etc. used in car coolers, air conditioning systems, etc., usually include a plurality of heat exchange tubes arranged in parallel between two tube sockets, each tube is connected at each end to a pipe socket. Corrugated fins are disposed in airflow gaps between adjacent heat exchange tubes and brazed to the corresponding tubes. Heat exchangers are typically made of aluminum or an aluminum alloy. [0003] In the past, flat refrigerant tubes were manufactured by folding a brazing sheet with a brazing filler...
