Heat exchanger for vehicle

摘要

According to the present invention, a pin-disposed portion (484) where a pin member (483) for mounting a heat exchanger on a vehicle is disposed is structured such that an inner edge shape of a cross section of the pin-disposed portion draws a four-sided closed curved line. The pin member passes through an inner space (485) of the pin-disposed portion and is connected to the pin-disposed portion at plural positions. In this way, the pin-disposed portion constructs a shell structure which is superior in a mechanical strength. Further, because the pin member is connected to the pin-disposed portion at plural positions while passing through the space, the shell structure of the pin-disposed portion can be made more rigid.
