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.
Claims7
A liquid cooled, heavy duty resistor comprising:
- a) a housing, said housing including a first insulating plate, a second insulating plate, and an insulating ring defining a chamber having an inlet and an outlet;
- and
- b) a bifilar wound spiral strip conductor resistor element, said resistor element
- i) arranged within said chamber, and
- ii) clamped between said first insulating plate and said second insulating plate to define a cross-sectional rectangular duct with said first insulating plate, said second insulating plate, and said insulating ring, said rectangular duct to provides a pathway between said inlet and said outlet for cooling liquid.
