Claim:
1. A heat exchanger for transferring heat between a gaseous first fluid and a liquid second fluid, comprising: a plurality of hollow pipes which extend transversely through a first fluid path for conducting the first fluid, the plurality of pipes externally being thermally coupled to a plurality of cooling fins arranged in the first fluid path, the plurality of pipes and the plurality of cooling fins configured to be flowed through by the first fluid, and wherein the plurality of pipes internally define a second fluid path for conducting the second fluid, wherein the plurality of pipes and the plurality of cooling fins are stacked on one another in a stacking direction to define a cooler block, the stacking direction extending transversely with respect to a main flow direction of the first fluid in the first fluid path, wherein the cooler block includes two side parts extending along two outer sides of the cooler block facing away from one another in the stacking direction, wherein the two side parts laterally delimit the first fluid path, wherein the two side parts are fixedly connected to one another via at least one tension rod, which is a component separate from the plurality of cooling fins and the plurality of pipes, wherein the at least one tension rod is configured to transmit a tensile force in the stacking direction, the at least one tension rod defining an extent in a width direction of the cooler block extending over a portion of a width of the cooler block, wherein the width direction runs transversely to the stacking direction and transversely to the main flow direction of the first fluid, wherein the at least one tension rod is arranged externally on at least one of an inflow side and an outflow side of the cooler block with respect to the first fluid path, and the at least one tension rod includes a base extending along the stacking direction and a plurality of prongs projecting from the base along the main flow direction of the first fluid, the plurality of prongs including at least two exterior prongs remote from one another and at least one interior prong, wherein the at least two exterior prongs overlap the two side parts and the at least one interior prong engages into the cooler block.
