Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] The structure of this system is as figure 1 As shown, the whole system includes engine water jacket 1, thermostat 9, HVAC 5, radiator 7, supercharger cooler 2, engine oil cooler 6, transmission heat exchanger 3, exhaust manifold water jacket 4 , Transmission temperature control valve 8, water storage pot 11, etc.

[0022] Engine water jacket 1 takes in water from the cylinder block and discharges water from the cylinder head. The water inlet of the engine water jacket 1 is connected with the first water outlet of the water pump 10 . The water inlet of the supercharger cooler 2 is connected with the second water outlet of the water pump 10 . The supercharger cooler 2 is connected in parallel with the engine water jacket 1 , and the water outlet of the supercharger cooler 2 is connected to the seventh water outlet of the engine water jac...

Abstract

The invention discloses a cooling system of quick preheating transmission machine oil. A transmission heat exchanger, an exhaust manifold water jacket and a transmission temperature control valve are added in a traditional cooling system; drained water of an engine water jacket is connected with a water inlet of a water pump by the exhaust manifold water jacket; heat of an exhaust manifold is leaded into the cooling system; the exhaust energy is effectively used; and meanwhile, the exhaust temperature is lowered, so that the injection of more fuels due to higher exhaust temperature under the working condition of higher load is prevented, and the oil saving effect is achieved. Meanwhile, the drained water of the engine water jacket is connected with the transmission temperature control valve, and then, is connected with the transmission heat exchanger; cooling water passes through the heat exchanger to connect with the water inlet of the water pump; a temperature control valve controls opening and closing of a transmission branch; when the temperature of cooling liquid is lower and dose not reach the water temperature demands for heating and defrosting in a passenger cabin, the temperature control valve is closed; when the temperature of the cooling liquid reaches the water temperature demands for heating and defrosting in the passenger cabin, the temperature control valve is opened; and the cooling liquid heats lubricating oil from a transmission through the heat exchanger to accelerate quick temperature rise of the transmission machine oil in cold start.

Description

technical field [0001] The invention relates to the technical field of automobile heat management, in particular to a cooling system for fast warm-up transmission. Background technique [0002] The transmission efficiency of the transmission is closely related to its oil temperature, low oil temperature and high friction, low transmission efficiency of the transmission. When a traditional car is cold started, the transmission only relies on its own frictional heat to heat up. The temperature of the engine oil rises very slowly, and there is no corresponding preheating measure, resulting in high friction and high fuel consumption of the transmission during cold start. At the same time, the heat of the combustion chamber of the engine is also low, which is generally only enough for the defrosting and heating of the passenger compartment. But on the other hand, the exhaust temperature of the car is very high, and the heat of the exhaust gas can basically not be used, wasting a...
