The present invention provides a charge air cooler for transferring heat between a coolant and charge air including a charge air inlet tank, a charge air outlet tank spaced from the inlet tank, a housing connecting the inlet and outlet tanks to define a charge air flow path from the inlet tank to the outlet tank, and a plurality of plate pairs extending into the charge air flow path from, and substantially perpendicular to, a first wall of the housing. Each of the plate pairs can define a multi-pass path for the coolant. Elongated spacers can be positioned between adjacent plate pairs to define the first wall of the housing. The housing can include a second wall opposite the first wall, and the plate pairs can be spaced away from the second wall in order to accommodate differences in thermal expansion between the plate pairs and the housing.
