Abstract:
1. A coolant system for a medical device, comprising: a first coolant reservoir; a first proportional valve in fluid communication with the first coolant reservoir; a first controller coupled to the first proportional valve; a coolant supply line in fluid communication with the first proportional valve; a vacuum source; a second proportional valve in fluid communication with the vacuum source; a second controller coupled to the second proportional valve; a sensor coupled to the second controller; and a coolant exhaust line in fluid communication with the second proportional valve, the system being operable in a first mode wherein the first coolant reservoir and vacuum source are fluidly isolated from each other and a second mode wherein the first coolant reservoir and vacuum source are in fluid communication with each other, the system operable to identify a leak based at least in part on signals from the sensor when the system is operable in the first mode.
