A heat exchanger, particularly a coolant evaporator, is provided that has several flat pipes that are arranged parallel to one another and are each expanded at their ends with respect to a central part and are closed off by caps. The expanded ends are provided with connecting openings so that the heat exchange medium can flow to the adjacent pipe. At least one of the caps that are provided for closing off the pipe ends is equipped with a projection extending towards the inside of the pipe and closes off at least one of the connecting openings, so that the production of a heat exchanger of identically constructed flat pipes is simplified, in that by the insertion of correponding caps that either expose the connecting openings to the adjacent pipes or not, it is easy to control the flow of the heat exchange medium inside the flat pipes.

A heat exchanger comprising: a plurality of flat pipes disposed parallel to one another for accommodating the flow of a first heat exchange medium therethrough, each of said flat pipes having first and second expanded end portions connected by a central portion of smaller cross-sectional area than the end portions such that the central portions of adjacent pipes are spaced from one another to accommodate flow of a second heat exchange medium thereby, each of said end portions including a pair of fluid openings for communicating said end portion with respective end portions of immediately adjacent pipes, and end cap means for each pipe for closing off said end portions at sides thereof facing away from the respective central portion, wherein at least one of said end cap means has an indentation extending toward a respective central portion to close off one of said fluid openings to block flow of said first heat exchange medium to an adjacent pipe end portion.
