Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oil temperature control apparatus,

The present invention relates to an oil temperature control device and a control method therefor of a vehicle that can reduce the friction between parts by making it possible to quickly and properly warm up the oil by using heat of the exhaust gas when the engine is driven .

During the initial start-up of the vehicle, the engine or transmission fluid must undergo a warm-up process at a low temperature and then at an appropriate temperature to maintain the engine and the transmission at an ideal temperature for operation.

The warm up method of the oil is generally a method in which the cooling water is first warmed up through the water jacket in the engine combustion chamber and the cooling water is heat exchanged with the oil again to make a secondary oil. However, this method is slow in warming up There is a disadvantage in that the method of quickly warming up by using the exhaust heat of high temperature has recently been widely applied.

In the case of a heat exchanger using exhaust heat, the exhaust gas and oil must be properly controlled step by step (before warming up, after warming up, etc.). Because of the heat exchange between the relatively high temperature exhaust heat and the relatively low temperature heat, durability problems such as fouling and oil carbonization, and exhaust gas emissions such as HC, CO, and NOx This is because it affects the occurrence.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

The apparatus for regulating the oil temperature of a vehicle according to the preferred embodiment of the present invention includes: a gas pipe (300, 300 ') through which a hot gas flows; A cooling water pipe 400 in which cooling water flows and the gas pipe 300 is inserted in the longitudinal direction so that the gas is cooled by the cooling water; An oil pipe 500 enclosing the cooling water pipe 400 from outside and having the gas pipe 300 'inserted therein to heat exchange oil with cooling water or gas; And an opening and closing part 600 provided to open and close the gas pipe 300 'inserted in the oil pipe 500 to cool or raise the temperature of the oil pipe 300' according to opening and closing of the gas pipe 300 '. In particular, the EGR gas may be introduced into the gas pipes 300 and 300 'through the EGR valve 200 of the engine 100. In addition, the opening and closing part 600 may be driven by a driving part 700 provided separately. The driving unit 700 includes a motor 710 and a gear 730 and a shaft 750. The gear 730 is rotated by driving the motor 710 and the shaft 750 is rotated to rotate the opening / Can be driven. The configuration of the driving unit 700 may be changed as much as the environment or design.

3, a plurality of the gas pipes 300 and 300 'are inserted into the cooling water pipe 400 and the oil pipe 500 in the longitudinal direction at a predetermined interval. Particularly, since the cooling water pipe 400 and the oil pipe 500 form a concentric circle, the oil of the oil pipe 500 can be more uniformly and quickly exchanged heat by the cooling water of the cooling water pipe 400 . The cooling water pipe 400 is provided with a cooling water inlet port 410 and a cooling water outlet port 430 in the radial direction of the cooling water pipe 400. The oil pipe 500 is connected to the oil pipe 500 in the radial direction An oil inlet 510 and an oil outlet 530 are provided so that cooling water flows into the cooling water pipe 400 and oil flows to the oil pipe 500.

The cooling water pipe 400, the oil pipe 500, and the gas pipes 300 and 300 'are provided on the front surface of the cooling water pipe 400, the oil pipe 500, and the gas pipes 300 and 300', respectively, to perform heat exchange before the warm- (600). The opening and closing part 600 is provided to open and close the gas pipe 300 'inserted in the oil pipe 500 so that the oil is cooled or raised according to the opening and closing of the gas pipe 300' To work.

Referring to FIG. 4, the opening / closing part 600 covers the inlet 310 of the gas pipe 300 '. Particularly, the opening / closing part 600 is provided with an inlet hole 610 at a position corresponding to the gas pipe 300 '.

Accordingly, the inlet hole 610 may be formed to be equal to or larger than the diameter of the gas pipe 300 '.

When the inlet hole 610 and the gas pipe 300 'coincide with each other and the inlet 310 is open, high-temperature EGR gas flows into the gas pipe 300' through the inlet 310, And heat exchange between the oil and the oil. In this case, the engine 100 is warmed up before the engine 100 is warmed up, and the engine 100 is warmed up quickly. In contrast, since the inlet hole 610 and the gas pipe 300 'do not coincide with each other, the high-temperature EGR gas is prevented from flowing into the gas pipe 300' through the inlet 310 when the inlet 310 is closed So that indirect heat exchange occurs between the cooling water of the cooling water pipe (400) and the oil of the oil pipe (500). This case is performed to cool the high temperature oil after warming up the engine 100.

The coating portion 630 is formed along the outer circumferential surface of the opening and closing portion 600 so that friction is reduced by the coating portion 630 when the opening and closing portion 600 rotates and at the same time, (300 '). Although the coating portion 630 is illustrated as being formed on the outer peripheral surface of the opening and closing portion 600 in the present specification, the coating portion 630 may be formed in each of the inlet holes 610. In order to solve the problem of sealing and friction reduction, The shape will be changeable.

More specifically, the opening / closing part 600 is a donut-shaped disk having a hollow 650 formed therein. The opening / closing part 600 is rotated by a separate driving part 700, The opening and closing part 600 is rotated by the driving part 700 by engaging the opening and closing part 600 with the driving part 700 by the engaging member 670. When the gas flows into the gas pipe 300 ', the engaging member 670 may have a slit shape so that the opening and closing part 600 can be smoothly rotated while overcoming the axial force in the gas inflow direction. Further, a coating unit (not shown) may be provided on the coupling member 670 for smooth rotation.

A plurality of the gas pipes 300 and 300 'are uniformly inserted into the cooling water pipe 400 and the oil pipe 500 at predetermined intervals and the warming up of the vehicle is performed by the opening / ) And the post-warm-up operation can be performed to perform the heat exchange. In the case of the gas pipe 300 provided in the cooling water pipe 400, the cooling of the EGR gas for lowering the temperature of the EGR gas supplied to the engine 100 through the EGR valve 200 of the engine 100 is performed .

The oil temperature control device of the vehicle as described above is advantageous in that the heat loss of the cooling water heat exchange module can be minimized by being insulated through a double radial canning structure. Prior to warm-up of the engine, direct heat exchange of gas and oil causes the oil to rise rapidly, preventing oil from accumulating in the cylinder head and accumulating in the cylinder head, and reducing friction between parts to increase fuel economy and durability of parts. In addition, it is possible to shorten the time to reach the optimum lubrication condition to reduce noise and vibration, and to increase the EGR cooling efficiency. After the warm-up, it performs fail-safe function to prevent overheating of the oil by indirect heat exchange between cooling water and oil, thereby enhancing the stability of the vehicle.
