SYSTEM AND METHOD FOR DETECTING LEAKS IN A SEALED COOLANT SYSTEM

A sealed cooling system includes a coolant tank having a liquid space configured to hold liquid coolant, and a gas space configured to hold gas. A temperature sensor detects the temperature of the liquid coolant. A pressure sensor detects the pressure in the coolant tank. A processor compares the pr...

Zusammenfassung:	A sealed cooling system includes a coolant tank having a liquid space configured to hold liquid coolant, and a gas space configured to hold gas. A temperature sensor detects the temperature of the liquid coolant. A pressure sensor detects the pressure in the coolant tank. A processor compares the pressure in the coolant tank to predicted pressure in the coolant tank as a function of liquid coolant temperature. The processor determines and outputs a signal indicative of a leak in the sealed cooling system if the pressure in the coolant tank deviates from the predicted pressure in the coolant tank according to predetermined criteria.
