Abstract
A partly damaged aluminum heat exchanger such as an aluminum radiator is repaired by closing a hole in the damaged portion with an acrylic resin adhesive material. A certain area around the damaged portion is pressed down to form a cup-shaped depressed portion. The adhesive material is supplied to the depressed portion so that it is retained therein. Then, the adhesive material is hardened by curing it under the room temperature. The hardened adhesive material completely closes the hole with a sufficient thickness and strength because it is retained in the depressed portion. The adhesive material is cured in a relatively short time because the acrylic resin is used as the adhesive material.
