Heat exchanger with fluid control means for controlling a flow of a heat exchange medium and method of manufacturing the same

A heat exchanger comprising

• tube for passing a heat transfer medium therethrough;
• tank connected to said tube;
• and
• at least one flow control member arranged within said tank to control the flow of said medium, said flow control member having a projection protruding from a peripheral edge;
• said tank having a protruding portion outwardly protruding therefrom to form at least one fitting groove in an internal wall of said tank, said fitting groove being adapted for receiving said peripheral edge of said flow control member,
• wherein said fitting groove is defined between a pair of side wall portions which are parallel to each other, said protruding portion having an insertion hole penetrating therethrough, said projection of said flow control member being inserted into said insertion hole, said projection having a top end smaller in size than said insertion hole, said projection being tapered so that the thickness and the width of said projection are reduced from a base portion to the top end, said projection and said insertion hole being coupled to each other.
