Patent attributes
A cooling jacket resistor includes a passageway incorporated into a wall and across the entire inside length of a cooling jacket from an inside of the cooling jacket. The passageway may include at least one sump and may have a depth that inclines from a first to a second end. The cooling jacket resistor may be positioned at the lowest point of the cooling jacket when installed in an electrical motor/generator. The cooling jacket resistor may collect condensed refrigerant in liquid form and may transport the condensed refrigerant towards a drain port by gravity. The condensed refrigerant may then be drained from the cooling jacket resistor through the drain port. The cooling jacket resistor may be suitable for, but not limited to, applications in electric motors or generators that uses vapor as a coolant, for example, two-stage refrigerant cooled vapor cycle compressors.
