Description

Engine oil cooler in oil pan

The present invention relates to an engine oil cooling device in an oil pan.

The engine oil, which has been lubricated and cooled while circulating each moving part of the engine, is returned to the oil pan and is then pumped up again by the water pump and circulated.

However, the engine oil is circulated and the returned engine oil receives heat and the temperature rises. When the temperature of the engine oil rises above a certain value, the oil deteriorates and the viscosity decreases greatly. (1) and the oil cooler installed separately.

However, the heat dissipation cooling that depends only on the oil pan (1) is inferior in cooling ability, and the installation of a separate oil cooler has a structure similar to a radiator, so that the installation structure is complicated and the layout of the engine room is limited, such as using engine coolant as a heat exchange medium. There is this.

Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide an engine oil cooling apparatus in an oil pan that greatly improves heat dissipation cooling property by using a simple structure of the engine oil stored in the oil pan to prevent deterioration. There is.

In order to achieve the above object, the present invention is an oil pan for storing engine oil, the rotating cylinder portion rotatably accommodated in the oil pan, and the heat conductor accommodated in a plurality of spaces formed inside the body of the rotating cylinder portion And a cylindrical case protruding from the center of the rotating cylinder and having a plurality of oil cylinders and holes formed on the outer circumferential surface thereof, and an oil filter accommodated in the cylindrical case to filter foreign substances in the oil supplied through the oil passage holes; It characterized in that it comprises a rotating shaft drawn out through the oil pan from one end of the rotating cylinder portion to the outside, and a pulley fixedly mounted to the end of the rotating shaft to receive the driving force of the crankshaft through the drive belt.

Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.

1 is a view showing the engine oil cooling device in the oil pan according to the present invention, Figure 2 is a cross-sectional view A-A of the in-phase device.

In the drawing, reference numeral 1 denotes an oil pan for storing engine oil, and the oil pan is mounted under the cylinder block.

In the oil pan 1, a rotating cylinder portion 2 is rotatably received, and a rotating shaft 3 extending from the rotating cylinder portion 2 extends out through the wall of the oil pan 1.

In the body of the rotating cylinder portion 2, a thermally conductive liquid, for example sodium liquid 4, is formed, which forms a space 2a and has excellent cooling property.

In addition, a cylindrical case 6 having an oil passage hole 5 through which oil flows in and out is protruded from the center of the rotating cylindrical portion 2, and an oil filter 7 is mounted in the cylindrical case 6. have.

In addition, a pulley 8 is fixedly mounted at an end of the rotating shaft 3, and the pulley 8 is rotated by receiving a rotational force from the pulley 11 of the crankshaft 10 through the driving belt 9.

Here, reference numeral 12 denotes a sealing ring for preventing leakage, and a bearing 13 supporting the rotating shaft 3 together with the seal may be installed outside the oil pan 1 body.

The present invention configured as described above rotates the rotary shaft 3 which supplies the rotational force from the crankshaft 10 when the engine is driven, and the rotary cylinder portion formed on the rotary shaft 3 as the rotary shaft 3 rotates. (2) rotates at a constant speed.

As the rotating cylinder part 2 rotates, the oil in the oil pan 1 mixes itself, and in this process, the sodium liquid 4, which is a thermal conductor, takes heat away from the oil, and the oil cools naturally, and the oil passes through the oil barrel. When passing through the hole (5), the foreign matter is removed by the oil filter (7) formed inside the cylindrical case (6) is to clean the oil.

The present invention as described above is rotated in the oil pan by receiving the driving force of the crankshaft, which causes the engine oil to be agitated naturally by the engine oil is stirred and also heat radiated and cooled quickly through the sodium liquid with excellent thermal conductivity, so that the temperature of the engine oil is increased. It can be drastically dropped, and as it rotates, it filters out impurities through the oil filter, thereby improving lubricity according to engine oil deterioration prevention and supplying cleanly filtered oil to the engine to prevent wear.
