Abstract

A heat exchanger for cooling crack gas has a number of cooling tubes (4), each surrounded by an outer tube (6). For the supply and removal of a coolant, the cooling tube (4) and outer tube (6) are each welded at both ends to a water chamber (7,8) which consists of a solid strip-shaped piece into which circular recesses (11) are let at a distance from one another. Each recess encloses a single cooling tube (4), the diameter of the recess is equal to or greater than the inside diameter of the outer tube (6), and the recess (11) has a thin, annular transverse plate (12) in the region of the end of the cooling tube with a small wall thickness. The strip-shaped piece forming the water chamber consists of individual sections (7.1, 7.2, 7.3, 8.2, 8.3) into each of which a single rebate (11) is let surrounding a cooling tube, and the sections (7.1, 7.2, 7.3, 8.2, 8.3) are joined to one another.
