Definitions
- the invention relates to a Heat exchanger according to the preamble of claim 1, and a method of manufacturing the heat exchanger.
- a heat exchanger of the type mentioned is out FR-A 2 121 757, where one possibility is described is cylindrical tubes in tube sheets of heat exchangers weld that into the openings of the tube sheets or if the tubes are pushed through to one end of the tube sheets are, in extensions of the pipes, a rotating one Electrode acts on an arc weld carries out and the melted and usually additionally supplied Material then forms a weld that both in the inner wall of the tube as well as in the surface of the Tube sheet leaks. Have the tube sheets used there but a strength that is significantly more than ten times that Thickness of the tube wall is. Such arc welds would look at thinner tube sheets, especially if they were made from Aluminum, do not allow to be carried out.
- DE 30 36 427 A1 describes a laser beam reflection system known with which it is possible to get one out to rotate an existing laser beam head mirror arrangement and therefore a circular weld with any diameter to manufacture.
- DE 30 36 427 A1 describes a laser beam reflection system known with which it is possible to get one out to rotate an existing laser beam head mirror arrangement and therefore a circular weld with any diameter to manufacture.
- the invention is therefore based on the object of a heat exchanger of the type mentioned at the beginning that the requirements for mechanical stability and tightness of the pipe-floor connection are met are, even if the dimensions of pipes and tube sheets are very small for weight reasons. Furthermore, a Methods of manufacturing the heat exchanger can be specified.
- the openings in the tube sheet are initially designed so that the Pipe ends kept largely gap-free in the openings are that the pipe ends are then in their assigned openings be inserted so that they are flush with the one at the collecting room adjoining side of the tube sheet, and that then laser welding through one along the circumference of the Tube ends guided laser beam takes place. That laser beam processes one pipe after the other and becomes this Purpose according to the dimensions of the tube sheet and the Pipes from pipe to pipe and then according to the circumference of the Pipe along.
- the Joining gap between the pipe ends and the assigned openings of the tube sheet is smaller than 0.1mm all around.
- the laser welding can also be done under protective gas, with a pulsed ND / YAG laser.
- the tubes (1) are with this tube sheet (2) along a their entire circumference weld (3) with the Tube plate (2) connected, which, as shown in Fig. 3, a has oval cross section with pointed ends, the Longitudinal axis (5) at about 45 ° to the tube sheet (2) and to Pipe axes (4) runs.
- the weld seam (3) by a Laser beam generated extends from one Not shown collection room facing the heat exchange medium Side (2a) of the tube sheet (2) to below it Underside (2b). It has a rounded, the pipe mouth facing inner contour (6), each tangent in the Side wall (2a) of the tube sheet (2) or into the inner wall (1a) the pipes (1) pass over.
- the weld seam therefore forms a kind Inlet funnel at the mouth of the pipes. It is pending nowhere on the inner wall (2a).
- the weld seam then receives that in FIG. 3 shown shape. It is at point (8), measured under one Angle of 45 ° the bisector between the bottom (2b) of the tube sheet (2) and the outer wall of the tube sheet (1) occupies greater than the wall thickness (s) of the tube (1); (a) is therefore greater than (s).
