Abstract
A heat exchanger includes a block for the separated and heat-exchanging guiding of first and second fluids, the block having a number of fluid flow channels, at least one box which is flow-connected to the flow channels, and at least one base that includes one or more openings for feeding the flow channels from the box. At least one opening is formed as a passage with a collar having a near-bottom section and an end-side section, and a wall thickness of the end-side section is smaller than a wall thickness of the near-bottom section. A shoulder between the near-bottom and end-side section has a contour running transverse to the contour of the near-bottom section and/or the end-side section, and the end-side section is inclined away from a passage axis. Also a manufacturing process for a heat exchanger.
