Sacrificial rods have been used in connection with shell and tube type heat exchangers to prevent corrosion of the cooling cores. These rods however have been employed with metallic heat exchanger components. The subject heat exchanger uses electrical non-conducting or plastic end covers which will not conduct a current flow. The end covers are provided with an electrical conducting metal sleeve, a metallic insert and an electrical conducting member which is connected in an electrical conducting relationship to the insert and at least one of the metallic sleeves. Thus, a grounded circuit is provided for the sacrificial rod. The reaction of the electrolyte and the rod prevents electrolytic damage to the core. |
