Definitions

the invention relates to a tube-bottom connection for a heat exchanger with a tube block through which a heat exchange medium flows and with aluminum tubes running parallel to one another, which are held at least at one end in an aluminum tube plate adjacent to a collecting space and are connected tightly thereto, in particular a cooler for automotive engines.
the invention is therefore based on the object of designing a pipe-floor connection of the type mentioned at the outset in such a way that the requirements for mechanical stability and tightness are met.
the invention is based on a tube-bottom connection of the type mentioned in that the tube ends inserted into the tube sheet are welded to the tube sheet by a laser weld seam running over their entire circumference, the inner contour of which is flush with the inner tube wall and into the interior of the collecting space facing side of the tube sheet merges.
the openings in the tube sheet are initially designed such that the pipe ends are held largely without gaps in the openings, so that the pipe ends are then pushed into their assigned openings, that they run flush to the sides of the tube plate adjacent to the collecting space, and that the laser welding is then carried out by a laser beam guided along the circumference of the tube ends.
This laser beam works one pipe after the other and is guided for this purpose according to the dimensions of the tube sheet and the pipes from pipe to pipe and then along the circumference of the pipe.
the laser welding can also be carried out under protective gas, using a pulsed ND / YAG laser.
the pipe-floor connection according to the invention for the heat exchanger serving as a cooler for motor vehicle engines consists of a plurality of flat pipes (1) which are arranged in a manner known per se and in a manner not shown and provided with a network of cooling fins
the tubes are aligned with their axis (4) perpendicular to the tube diode (2). They have a wall thickness (s) which, in the exemplary embodiment, is substantially less than the thickness (b) of the tube sheet (2).
the thickness (b) is approximately three times the wall thickness (s) of the pipes (1).
the tubes (1) are connected to this tube sheet (2) via a weld seam (3) running along their entire circumference with the tube sheet (2), which, as shown in FIG. 3, has an approximately oval cross section with pointed ends, the Longitudinal axis (5) runs at approximately 45 ° to the tube sheet (2) and to the tube axes (4).
the weld seam (3) which was generated by a laser beam, extends from the side (2a) of the tube sheet (2) facing a collecting space (not shown) for the heat exchange medium to below the underside (2b) thereof. It has a rounded inner contour (6) facing the pipe mouth, each tangent into the Side wall (2a) of the tube sheet (2) or in the inner wall (1a) of the tubes (1) merges.
the weld seam therefore forms a kind of inlet funnel at the mouth of the pipes. At no point does it project beyond the inner wall (2a).
the laser beam therefore processes all tubes (1) one after the other on the side that is flush with the tube sheet (2).
the weld seam is then given the shape shown in FIG. 3.
point (8) measured at an angle of 45 °, which the bisector between the underside (2b) of the tube sheet (2) and the outer wall of the tube sheet (1) occupies, it is greater than the wall thickness (s) of the tube (1); (a) is therefore larger than (s).
