DEVICE FOR A HEAT EXCHANGER FOR COLLECTING AND DISTRIBUTING A HEAT TRANSFER FLUID

摘要

A device for a heat exchanger has a hollow cylindrical header and a plurality of flat tubes. A wall of the header includes a plurality of through openings. The flat tubes are received in the through openings through the wall into the inner cross-section of the header tube, and are aligned with the width of the flat tubes parallel to the direction of the inner dimension. A width of the flat tubes is greater than an inner dimension of the inner cross-section and is smaller than the outer dimension of the header tube, wherein the through openings are embodied as having grooves that continue in the wall of the header tube into the inner cross-section. The flat tubes, which are guided in the through openings through the wall, are arranged in the grooves.
