Abstract:

A method of remanufacturing coolers, such as exhaust gas recirculation coolers, is provided. The method includes providing an exhaust gas recirculation cooler having cooling tubes attached to a header plate and an outer shell. At least one opening is milled in the outer shell to expose a portion of the cooling tubes. Brazing material is then injected into the cooler through the opening such that the brazing material, when heated, forms a fillet around each cooling tube adjacent to the header plate. A cover positioned over the opening and the cooler is heated to a brazing temperature, such that the brazing material flows around the cooling tubes, thereby reinforcing the tubes and repairing cracks in the tubes. Clips having a C-shaped configuration may also be positioned within the cooling tubes to further strengthen and repair the cooling tubes.
