Description

Plate for oil cooler and oil cooler comprising the same

The present invention relates to an oil cooler, and more particularly, to an oil cooler plate and an oil cooler having the improved structure of a plate interposed with an inner fan.

Typically, the oil cooler allows the oil introduced into the oil cooler to be cooled by the outside air or the coolant of the radiator while passing through the oil cooler to prevent the temperature rise of the oil flowing inside the transmission, and then back to the transmission system. It serves to send.

Conventional oil coolers allow oil to pass through a plurality of plates stacked between a pair of tanks, and at this time, oil passing through the inside of the plate by heat exchange due to contact between the outer surface of the plate and the outside air. The plate is configured to allow cooling, wherein each plate includes an inner fin interposed between the upper plate and the lower plate and the upper plate and the lower plate which are mutually coupled to each other.

Such inner shocks can improve heat exchange performance by promoting turbulence of oil flowing inside the plate, and play a role of improving the pressure resistance performance of the oil. In order for the inner shock to achieve such performance, the position of the inner shock needs to be controlled inside the plate.

In the related art, as shown in FIG. 1, the bead portion 14 having a predetermined thickness is disposed in front of the tank portion 13 formed at both ends of the plate 11 to fix the inner fin 12 inside the plate 11. And the inner fin 12 is plate 11 by mutually joining the pair of plates 11 in a state where both ends 12a of the inner fin 12 are supported by the bead portion 14. Set location inside.

By the way, the conventional oil cooler plate has the following problems.

The bead part 14 for fixing the said inner fin 12 protrudes in the center of the width direction of the plate 11 adjacent to the tank part 13 of the both ends of the plate 11, respectively. For this reason, the length of the inner fin 12 is reduced by the area A in which the bead part 14 is formed from the outer peripheral surface of the tank part 13, and there exists a disadvantage that the acceleration of turbulence of oil and the raise of internal pressure fall.

In addition, the bead portion 14 is vulnerable to strength as the thickness of the bead portion 14 protrudes in the center of the plate 11. In addition, when the pair of plates 11 are joined, the bead portions 14 formed on each plate come into contact with each other, so that the joining points between the bead portions 14 are vulnerable to internal pressure.

The present invention is to solve the above problems, and provides an oil cooler plate and an oil cooler having the same that can be firmly fixed by controlling the position of the inner 휜 provided in the inside of the oil cooler plate more easily. Its purpose is to.

Another object of the present invention is to provide an oil cooler plate capable of improving the performance of promoting the turbulence of the oil flowing in the plate and increasing the internal pressure by extending the length of the inner fin provided inside the plate for the oil cooler to the maximum, and the same. One oil cooler is to provide.

Still another object of the present invention is to provide an oil cooler plate capable of increasing the bonding strength and thereby improving the pressure resistance performance by enlarging the mutual coupling area of the upper plate and the lower plate provided in the plate for oil cooler and having the same. To provide an oil cooler.

The plate 210 of such a shape is formed with the junction part 215 of predetermined thickness along the edge of the opposing part of each shaping | molding surface 213,214. The joint 215 is preferably formed on the corresponding surfaces of the upper and lower plates 211 and 212, and provides a surface to which the upper and lower plates 211 and 212 are welded to each other. .

An inner space is formed between the upper and lower plates 211 and 212 coupled to each other due to the thickness of the junction portion 215, and an inner fin 240 is interposed therein. The inner fin 240 is formed to be wrinkled in the width direction of the plate 210.

At this time, the upper and lower plates 211 and 212 have at least one bead-shaped position control unit to set the position in the longitudinal direction of the inner fin 240 in a portion connected to the tank unit 220 ( 40) is formed.

That is, the position control unit 40 is formed on the plate 210 from the junction 215 formed along the edges of the forming surfaces 213 and 214 of the plate 210 to provide a welding surface. It is formed along the circumference of the tank portion 220.

It will be preferred that the maximum length of the fin 240 can be designed.

The position controller 40 has a thickness substantially the same as that of the junction portion 215, and it will be advantageous for the manufacturing process to simultaneously mold the junction portion 215.

Accordingly, as shown in FIG. 5, the inner fin 240 is positioned at both ends 241 and 242 by the position control unit 40, and the position control unit 40 controls the inner fin ( 240 serves as a stopper that can set the position in the longitudinal direction of the inner fin 240 so as not to invade the area where the tank portion 220 is formed.

In addition, since the position control unit 40 extends from the inner side wall of the junction part 215 so as to be out of the outer diameter of the tank part 220, and is formed along the circumference of the tank part 220, the inner shock 240 may be formed as described above. It may be possible to maximize the length to the boundary portion in contact with the tank 220.

Looking briefly at the operation of the oil cooler 200 having the structure as described above.

The first heat exchange medium introduced from the flow path of the transmission oil (ie, the first heat exchange medium) flows into the inlet boss 231 of the oil cooler 200 inserted into the lower tank of the radiator, which is stacked plate 210. Will flow inside).

At this time, since the cooling water (ie, the second heat exchange medium) cooled by the heat exchange with the outside air is circulated between the stacked plates 210, the high temperature first heat exchange medium flowing inside the plate 210 is a second low temperature medium. The temperature is lowered through heat exchange with the heat exchange medium and then discharged back to the discharge boss 232. This process is repeated by forced circulation return by the action of the transmission oil pump.

Here, the inner heat exchanger 240 is positioned inside the plate 210 by the bead-shaped position controller 40 protruding from the joint 215 that provides the welding surface. It improves heat transfer performance by promoting turbulence.

On the other hand, the second heat exchange medium is heated from the engine, cooled by the air and forced convection heat transfer by the operation of the cooling fan outside the radiator and forcedly circulated by the water pump.

Alternatively, it is a matter of course that the oil cooler according to the features of the present invention is also applicable to the case where it is attached to the outside of the tank part of the radiator.

As described above, the oil cooler plate of the present invention and the oil cooler having the same can obtain the following effects.

First, as the bead-shaped position control portion protruding from the joining portion of the plate into the molding surface is formed, the inner jaw can be supported in parallel at both ends so that the position thereof can be controlled more easily.

Second, by extending the length of the inner fin interposed in the plate to the maximum in contact with the tank portion, it is possible to improve the performance of the turbulence acceleration and internal pressure rise of the oil flowing through the plate.

Third, by increasing the area of the upper and lower plates to be welded to each other, it is possible to increase the bond strength and thereby to improve the breakdown voltage performance.
