Abstract

See full text

A heat exchanger may include an outer casing extending in a longitudinal direction and delimiting a volume through which a first fluid is flowable, and a tube bundle including a plurality of tube bodies arranged in the volume and through which a second fluid is flowable. In a cross section, the volume may have an inner surface area and an inner circumference and each tube body may have an outer circumference and an outer surface area. A ratio of a sum of the outer circumferences to the inner circumference may be at least 5.5, and a sum of the outer surface areas may account for 64% or less of the inner surface area. A residual cross section area of the inner surface area may be delimited between the outer casing and the plurality of tube bodies.
