ABSTRACT:
A heat exchanger for cooling cracked gas. At least one cooling pipe (4) is enclosed in an outer pipe (6). Both pipes are welded at each end to a water compartment (7 & 8). The water compartment supplies and removes a coolant. Each water compartment comprises a solid strip with as many separated and circular depressions (11) introduced into it as there are cooling pipes. Each depression surrounds a cooling pipe. The diameter of each depression equals or exceeds the inside diameter of the outer pipe. Each depression has a thin annular floor (12) with a slight residual thickness in the vicinity of the ends of the cooling pipes.
