The invention discloses a cooling liquid and engine oil heat exchange device in the technical field of internal combustion engines. The cooling liquid and engine oil heat exchange device comprises an engine, an air inflow and exhaust system, a cooling liquid guide-out pipe, a cooling liquid guide-back pipe, a heat exchanger and an electromagnetic valve; a water inlet of the cooling liquid guide-out pipe and a water outlet of the cooling liquid guide-back pipe are both connected with an engine cooling system; the heat exchanger is arranged in an oil pan; a water outlet of the cooling liquid guide-out pipe and a water inlet of the cooling liquid guide-back pipe are both connected with the heat exchanger after penetrating a shell of the oil pan; and the electromagnetic valve is arranged on the cooling liquid guide-out pipe and connected with an engine electronic control unit. When the engine runs under the idle speed or small load work condition, cooling liquid can fast raise the temperature of engine oil in the
