- the heat exchanger is preferably an intercooler which is arranged in a fresh air system for supplying an internal combustion engine with fresh air downstream of a charging device, for example a turbocharger, in order to cool the compressed and thereby warmed charge air before it engages the combustion chambers of the internal combustion engine is supplied.
- Such a heat exchanger may, for example, be configured as a ribbed-tube heat exchanger and accordingly have a plurality of tubes extending through a first fluid path for guiding the first fluid, which heat-transmitting externally with arranged in the first fluid path, by the first fluid through or flow around cooling fins are coupled and form the inside of a second fluid path for guiding the second fluid.
- the heat exchanger forms a charge air cooler flows in the tubes, a liquid coolant, while in the region of the cooling fins, the charge air flows.

With the help of such tie rods tensile forces can be transmitted in the stacking direction between the two side panels, without causing the cooling fins and the pipes and their connections are excessively burdened. The risk of damage to the cooling fins or their connection to the tubes or to the respective side part can thereby be significantly reduced.
- At least one such tie rod may be arranged on the outside of the radiator block on an inflow side of the radiator block with respect to the first fluid path or on an outflow side of the radiator block with respect to the first fluid path and connect the two side parts on said inflow side or on said outflow side. It is clear that in the event that at least two such tie rods are provided, at least one such tie rod can be arranged both on the upstream side and on the downstream side.

- the respective side part can have a collar on an upstream and / or on an outflow-side edge, which protrudes outwards, that is, away from the cooling ribs and the tubes, in particular parallel to the stacking direction. With the help of such collar, the flexural rigidity of the respective side part can be increased accordingly.
- At least one such tie rod can now be configured so that it engages around such a collar of the respective side part with an end region.
- a positive connection between said tie rod and the respective side part is also realized.

This also allows a particularly simple positive connection can be realized, which can reliably transmit high tensile forces.
- at least one such tie rod can be designed comb-like, so that it has a parallel to the stacking direction extending base and at least three parallel to the main flow direction of the first fluid from the base projecting tines. At least three such prongs are provided, namely two outer prongs and at least one inner prongs.

- the fresh air duct expediently has a coupling with the respective side part of the heat exchanger on two opposite channel walls, which in particular can transmit tensile forces. In this way, the channel walls can transmit tensile forces on the side parts and thus on the radiator block, which are largely absorbed in the heat exchanger according to the invention by the respective tie rod.
- the coupling between the respective channel wall and the respective side part may expediently be designed as a bypass seal in order to avoid a flow around the heat exchanger on the fresh air side.

- each item 42, 43 on the edge side has an L-shaped projection, which join together in the joint to the T-shaped profile of the sealing contour 13.
- the respective tie rod 23 regardless of the respective embodiment, extends in the width direction 12 of the radiator block 8 only over a relatively small part of the entire width of the radiator block 8.
- the respective tie rod 23 extends in the width direction 12 over a maximum of 10%, preferably over a maximum of 5%, the entire width of the radiator block. 8
