Abstract
Apparatus for cooling the power electronics components of a variable frequency drive for the motor of a refrigerant system compressor. The components are mounted upon a heat sink and refrigerant from the system condenser is passed through the heat sink by means of a flow line and returned to the low pressure side of the system. A control valve is mounted in the flow line which throttles refrigerant passing through the line to produce cooling of the heat sink to maintain the temperature of the components within a desired range.
