Abstract
A corrodible container for the storage of a corrosion inhibitor to be suitably located in the coolant system of an automotive vehicle or other environment wherein the container has at least a portion thereof formed of substantially the same material as the material forming the heat exchange device in a coolant system so as to corrode when the coolant is partially or wholly replaced by a corrosive liquid such as water. More specifically, an aluminum radiator has a tendency to corrode rapidly where corrosive water is present and the container for the corrosion inhibitor has at least a portion thereof formed of aluminum foil or aluminum sheet material with a thinner portion so that the foil or thinner portion will corrode through to release the corrosion inhibitor into the coolant to minimize corrosion of the heat exchanger and coolant system.
