Abstract
The hoist control cooling system for preferentially cooling components of a variable frequency drive that is controlling a hoist motor. The cooling system includes an inverter temperature sensor, an ambient temperature sensor, a cooling system controller, an inverter cooler, and an ambient cooler. The inverter temperature sensor measures the temperature of the inverter and generates an inverter temperature signal. The ambient temperature sensor measures the temperature of the ambient air in the sealed control enclosure and generates an ambient temperature signal. The cooling system controller communicates with the inverter temperature sensor and the ambient temperature sensor by receiving the inverter temperature signal, the ambient temperature signal, and generating both an inverter cooling signal, and an ambient cooling signal. The inverter cooling signal controls the cooling of the inverter. Similarly, an ambient cooling signal switches the ambient cooler on, thereby cooling the ambient air temperature in the sealed control enclosure.
