Abstract
An evaporator includes a cylindrical aluminum pipe, and two aluminum flanges which are fixed to both end surfaces of the aluminum pipe by screws. Screw holes into which screws are inserted can be formed in the wall of the aluminum pipe in a direction of the axis of the aluminum pipe simultaneously upon extrusion of the aluminum pipe. Communicating holes formed in the flanges communicate each set of two adjacent through holes among a plurality of the through holes formed in the wall of the aluminum pipe, thereby constructing one continuous coolant flow path inside the evaporator.
