Claim Text:
1. A cooling system using coolant solution, comprising: a heat generation device generating heat; coolant solution that exchanges heat with the heat generation device to cool the heat generation device; a temperature sensor that detects a temperature of the coolant solution; a conductivity sensor that detects a conductivity of the coolant solution; and a controller that determines a condition of the coolant solution based upon the detected coolant solution temperature and the detected coolant solution conductivity that are detected through the temperature sensor and the conductivity sensor, wherein the controller calculates a compensation coefficient based upon the detected coolant solution temperature and the detected coolant solution conductivity, the controller detects a first conductivity C1 of the coolant solution and a first temperature T1 of the coolant solution at a predetermined first point in time, and the controller detects a second conductivity C2 of the coolant solution and a second temperature T2 of the coolant solution at a predetermined second point in time, the compensation coefficient (C_coef) is calculated through a formula: and when the controller determines that the compensation coefficient exceeds a predetermined range, the controller determines that the coolant solution is in an abnormal condition and generates an alarm signal to light an emergency lamp of a cluster or sound an alarm.
