An improved heat exchanger for an automotive vehicle, comprising at least one end tank; and at least two heat exchangers including a plurality of spaced apart metal tubes with fins between the spaced tubes. The heat exchangers are preferentially disposed so that their respective tubes and fins are generally co-planar with each other and are connected to the end tank. In preferred embodiments, the heat exchanger may include a radiator element.

Heat exchanger

An improved heat exchanger for an automotive vehicle, comprising at least one end tank; and at least two heat exchangers including a plurality of spaced apart extruded metal tubes with fins between the spaced tubes. The heat exchangers are disposed so that their respective tubes and fins are generally co-planar with each other and are connected to the end tank. In preferred embodiments, the heat exchanger may include a bypass element.

A fin louver design using breaking and reversal louvers whose lengths are substantially longer than the half-length of the main louver but at slightly lower angles to the fin face, in order to increase the heat transfer while reducing or minimizing the airside air pressure drop. The reversal louvers will not dramatically change the airflow direction but rather permit air to follow the louver direction, thus preventing any dead area where the air speed is approximately zero in the central part between the two reversal louvers. Contact is provided between fresh moving air and the central part between the two reversal louvers.
