To provide a cooling system of a hybrid vehicle which suppresses the freezing of condensed water in an intercooler.SOLUTION: A cooling system of a hybrid vehicle comprises: an engine cooling path in which cooling water circulates between a radiator and components for an engine; a hybrid cooling path which branches off from the engine cooling path and is connected to the engine cooling path again, and in which the cooling water circulates between the radiator and special components for the hybrid vehicle; an intercooler which is provided on the hybrid cooling path; a bypass path which bypasses the intercooler; a valve mechanism which can adjust the flow rate of the cooling water flowing through the intercooler and the flow rate of the cooling water flowing through the bypass path; and a control device which controls the valve mechanism such that the flow rate of the cooling water flowing through the intercooler is reduced and the flow rate of the cooling water flowing through the bypass path is increased in a case where the temperature of the cooling water is equal to or less than a prescribed value in comparison to a case where the temperature of the cooling water is greater than the prescribed value.SELECTED DRAWING: Figure 2
