Abstract

A liquid cooled, heavy duty resistor including a housing and a resistor element. The resistor element is arranged inside a chamber defined by the housing. The resistor element and the housing form a rectangular duct through which a cooling liquid flows from an inlet to an outlet. The chamber is defined by two insulating plates and an insulating ring. The resistor element is a bifilar wound spiral strip conductor and is clamped between two insulating plates such that the cooling liquid flows through the rectangular duct. The liquid cooled, heavy duty resistor can remove a high dissipated power in a small space, has low inductance, and has a low resistance value.
