Heat exchanger e.g. cooling liquid heat exchanger for use in motor vehicle, has tubes interacting with openings of collecting tank and header tank such that end of each tube has contour

摘要

The heat exchanger comprises tubes (11) made of sheet-metal strip, for regulating the temperature of a medium such as coolant and charge air flowing through the tubes. The ends of the tubes interact with the openings (23) in a collecting tank (24), header tank (25) such that end (21) of each tube has a contour (220). Independent claims are included for the following: (1) cooling liquid heat exchanger; and (2) heat exchange liquid heat exchanger.
