Abstract
A liquid cooling system with a reverse bias system is described. The reverse bias system serves several functions, including monitoring a corrosion in the liquid cooling system as well as providing a reverse bias voltage to reduce a galvanic current in the system and to prevent corrosion in the liquid cooling system. The reverse bias system in the liquid cooling system allows for heterogeneous usage of metallic materials, which results in a lighter weight and easier to fabricate liquid cooling system.
