Abstract

A heat exchanger for transferring heat between a gaseous first fluid and a liquid second fluid may include a plurality of hollow pipes extending transversely through a first fluid path for conducting the first fluid. The plurality of pipes may be coupled externally to a plurality of cooling fins arranged in the first fluid path. The plurality of pipes may internally define a second fluid path for conducting the second fluid. The plurality of pipes and the plurality of cooling fins may be arranged stacked on one another in a stacking direction to define a cooler block. The cooler block may include two side parts extending along two outer sides of the cooler block facing away from one another in the stacking direction. At least one tension rod may fixedly connect the two side parts and be configured to transmit a tensile force in the stacking direction.
