A cooler for an internal combustion engine may include a cooler block including a gas path for communicating a gas flow along a gas flow direction and a coolant path for communicating a coolant flow. The gas path and the coolant path may be thermally coupled to each other and may be fluidly separated from each other. The cooler may include a liquid separator for separating a liquid from the gas flow. The liquid separator may be arranged on the cooler block at an outlet side of the gas path. The liquid separator may include a reservoir for the separated liquid and an evaporator for evaporating the separated liquid.
