Abstract: A heat exchanger, such as a water cooled charge air cooler, is disclosed for cooling of charge air with the aid of coolant. In at least one embodiment, the heat exchanger includes charge air tubes and coolant turbulators made of corrugated sheet metal interposed between the air tubes. The turbulators define coolant channels and including at least one turbulating device provided therein. According to at least one embodiment of the invention, at least one channel includes at least one continuously shaped side wall which is non-apertured along its entire length and thus promotes coolant flow along the channel by inhibiting cross flow of coolant to a neighbouring channel.

Abstract: The invention relates to a heat exchanger (1) comprising a coolant housing (10) and a header plate (20). The header plate (20) crimps around a border (11) of the coolant housing (10) by encompassing the border (11). The header plate (20) is provided with apertures (22), each aperture (22) receiving a tube (30) for guiding coolant from or to the closed cavity (50). The heat exchanger (1) further comprises a reinforcing plate (40) extending between two opposing crimped locations on the border (11) of the coolant housing (10), and extending on the outside of the header plate (20) in view of the closed cavity (50), wherein the reinforcing plate (40) is joined, at the opposing locations, to an outer surface portion of the header plate (20), and wherein the reinforcing plate (40) is provided with at least one aperture (42) embracing one or more of the tubes (30) received by the header plate (20).

Abstract: The invention concerns a heat exchanger and a method of producing thereof. The heat exchanger comprises a coolant housing with two opposing wide side walls and two header plates of an inlet air tank and an outlet air tank, respectively. The header plates are channel-shaped with longitudinal flanges extending over and being brazed to the wide side walls. Tubes extend in parallel through said housing between the two header plates, said tubes being brazed to apertures in said header plates. The coolant housing has two opposing narrow side walls tightly fitting said wide side walls and said header plates and defining together with these wide side walls and header plates a first coolant tank and a second coolant tank opposing the first one. Each air tank comprises a cowling tightly fitting and being brazed to one of said header plates each and having an air inlet and an air outlet, respectively.
