BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling water temperature control apparatus and, in a forced circulation type water cooling engine employing an outlet control method, relates to a cooling device that combines engine oil cooling of an automobile capable of efficiently cooling engine oil through separate circulation of cooling water.

Conventionally, a general automotive cooling water pump is a device installed in an engine room to force circulation of the cooling water in the engine and the cooling water of the radiator. The engine can be cooled, but the oil cannot be cooled, and there are problems in maintenance and durability. There were a lot.

The present invention is made in view of such a conventional problem.

In the forced circulation type water-cooled engine employing the outlet control method, an object of the present invention is to control the temperature of a coolant that combines engine oil cooling of an automobile, which enables efficient engine oil cooling through separate circulation of the coolant.

Based on the present invention; The first inlet provided on one side of the cylinder block is communicated by the radiator lower tank and the first inflow passage, and the first outlet provided on one side of the cylinder head is also communicated by the radiator upper tank and the outlet passage, On the first inlet side of the inlet passage, a first water pump of the coolant inlet means is installed to operate with engine driving force, and on the first outlet side of the outlet passage, a coolant outlet means, a thermostat of the water temperature control means, and a temperature sensing means are installed. And, the first water pump and the thermostat is in communication with the first bi-pass passage to reduce the water temperature gap, the oil pan (oil pan) of the oil storage means is installed at the bottom of the cylinder block, An inner oil fan provided with several cooling fins having heat dissipation means on its outer periphery, and an inlet provided with a second inlet and a second outlet. Sealing the space between the emitter and the oil pan, and the inner oil pan and an outer oil pan, the water end, and the water jacket is provided, respectively, are also configured such that the oil temperature sensor installed lower portion of the oil temperature sensing means and the ECU relay connection.

The first inlet passage and the second inlet are communicated by the second inlet passage, and the second outlet 23 is communicated by the bypass passage of one side of the cylinder head and the bypass passage of the cooling water bypass means. On the inflow passage, a second water pump of another coolant inflow means interlocked by a separately installed drive motor 24 to force circulation of the coolant is installed, and a check valve of the coolant backflow prevention means is installed on the second bypass passage. It is a cooling device cooling device which also serves to cool the engine oil of a vehicle configured.

Engine oil cooling and engine cooling apparatus of the present invention constituted as described above; Through the first inflow passage, the cold water in the radiator lower tank flows to the engine body, the cylinder and the water jacket around the combustion chamber according to the open short of the thermostat resulting from the rise of the cooling water temperature in the warm air, and the second inflow passage When the oil temperature rises above the set value in warm air, the second water pump operates by supplying electric power to the drive motor electrically connected to the ECU according to the output signal of the oil temperature sensor. Cold water in the tank flows to the water jacket of the oil pan to cool the superheated oil.

When the oil in the oil pan reaches the proper temperature and the cooling is completed, the ECU automatically cuts off the electric power of the drive motor by the signal of the oil temperature sensor, thereby preventing the coolant from flowing into the oil pan water jacket.

In addition, the check valve is connected to the oil fan water jacket through the bypass hole of the cylinder head during the operation condition in which the oil maintains the proper temperature, that is, the second pump is not operated and the circulation of the first pump is performed. To prevent backflow.

The present invention prevents the deterioration of the oil by preventing the rise of the temperature of the engine oil to prolong the life of the oil, the oil is always maintained at the optimum temperature for lubrication, thereby maximizing the lubrication action and the life of the engine.

The invention is explained in more detail by way of the preferred embodiments and the drawings.
