A method of manufacturing a header pipe for a heat exchanger, including (a) forming a header pipe as a single body with a vertically separating panel between first and second channels, including a plurality of slots through the pipe adapted to connect to cooling fluid tubes of a heat exchanger, (b) introducing a punch into the inside of one of the channels of the header pipe with more than one nipple facing one side of the separating panel, (c) inserting a die into the inside of the other of the channels of the header pipe with punching holes aligned with the punching nipples and the other side of the separating panel, (d) inserting a pressuring pole of a pressuring device through the header pipe slots into the one channel, and (e) moving the pressuring pole to press the punch toward the separating panel to punch more than one hole into the separating panel.
