  • Patent number: 9951677
    Abstract: A charge-air cooling device for a fresh air system of an internal combustion engine may include a housing which contains a charge-air duct and a heat exchanger having an internal coolant path and an external charge-air path. The housing may have a mounting opening, through which the heat exchanger is pushed into the housing in a longitudinal direction of the heat exchanger such that, in a pushed-in state, the charge-air duct leads through the charge-air path. The housing may include at least one wall in a receiving region which receives the heat exchanger. The wall may be elastic and, by the heat exchanger being pushed into the receiving region, the wall may be transferred from a relaxed state when the heat exchanger has not been pushed into the receiving region, into a stressed state when the heat exchanger has been pushed into the receiving region.
