Claims

[Claims for Utility Model Registration] Two devices having a plurality of connection holes and arranged in parallel.
In a heat exchanger comprising a main header pipe, a plurality of tubes connected by inserting both ends into connection holes of each header pipe, and heat transfer fins interposed between the tubes, the above-mentioned. A heat exchanger characterized in that a part of the inner surface of the header pipe is formed with an abutment surface that forms an acute angle with respect to a plane perpendicular to the insertion direction of the tube and that the insertion end of the tube comes into contact with.
