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

    【課題】インタークーラ内での凝縮水の凍結を抑制するハイブリッド車両の冷却システムを提供する。【解決手段】ハイブリッド車両の冷却システムにおいて、ラジエータとエンジンに関する部品との間で冷却水が循環するエンジン冷却経路と、エンジン冷却経路から分岐して再びエンジン冷却経路に接続され、ラジエータとハイブリッド車両の専用の部品との間で冷却水が循環するハイブリッド冷却経路と、ハイブリッド冷却経路上に設けられたインタークーラと、インタークーラをバイパスしたバイパス通路と、インタークーラを流れる冷却水の流量とバイパス通路を流れる冷却水の流量とを調整可能な弁機構と、冷却水の温度が所定値以下の場合には、冷却水の温度が前記所定値よりも高い場合よりも、インタークーラを流れる冷却水の流量が低下しバイパス通路を流れる冷却水の流量が増大するように弁機構を制御する制御装置と、を備えたハイブリッド車両の冷却システム。【選択図】図2
