METHOD FOR FORMING END PLATE FOR HEAT EXCHANGER AND HEAT EXCHANGER EQUIPPED WITH END PLATE FORMED WITH THIS METHOD

摘要

A method for forming an end plate for a heat exchanger and a heat exchanger formed by this method are provided. The endplate is formed by preparing a concave die including a groove bottom surface and a pair of groove wall surfaces extending from both ends in the width direction of the groove bottom surface; preparing a convex die including a convex top surface facing the groove bottom surface of the concave die, convex wall surfaces facing the groove wall surfaces of the concave die, and protrusions provided along both sides in the width direction of the convex top surface; and inserting a plate member between the concave die and the convex die.

1. A method for forming an end plate for a heat exchanger, the heat exchanger including:
a pair of headers spaced from one another and extending in parallel with one another; a plurality of heat exchanger tubes spaced from each other in a header extending direction, each of the heat exchanger tubes being connected to the headers at both ends; heat-transfer fins provided between adjacent heat exchanger tubes and also provided on outer sides of outermost heat exchanger tubes in the header extending direction; and end plates provided on the outer sides of the top and bottom heat-transfer fins, respectively, in the header extending direction, each of the end plates including a base part contacting a heat-transfer fin and extension parts extending from both sides in a width direction of the base part toward an outside of the header extending direction, the method comprising:
preparing a concave die including a groove bottom surface and a pair of groove wall surfaces extending from both ends in the width direction of the groove bottom surface;preparing a convex die including a convex top surface facing the groove bottom surface of the concave die, convex wall surfaces facing the groove wall surfaces of the concave die, and protrusions provided along both sides in the width direction of the convex top surface; andinserting a plate member between the concave die and the convex die to form an end plate.
