Description

Oil cooler

The present invention relates to an oil cooler used in automobiles and the like.

2. Description of the Related Art Generally, an oil cooler is a device for discharging a high-temperature heat source discharged from an engine or a transmission of an automobile to the outside. The oil cooler is provided in a form of cooling oil for transferring exhaust heat.

Such an oil cooler is mainly configured to be accommodated in a radiator or the like and cooled by cooling water of a radiator.

The oil cooler accommodated in the radiator has a structure in which a plurality of tubes each having an oil passage through which oil passes are stacked and a cooling water flow passage through which cooling water passes is formed between the tubes. Accordingly, the oil passes through the inside of each tube, and as the cooling water passes through the outside of each tube, the oil in the tube cools.

1 and 2, a conventional oil cooler includes a plurality of tubes 10 (hereinafter, referred to as " oil coolers ") each composed of an upper plate P1 and a lower plate P2, A plurality of cooling fins 20 provided between the respective tubes 10a, 10b, 10c and 10d and through which the cooling water is passed and a plurality of cooling fins 20 through which the tubes 10a, 10b, 10c, 10b, 10c, and 10d, which communicate with one end portion of each of the tubes 10a, 10b, 10c, and 10d to introduce oil into the respective oil passages 11a, 11b, (Not shown) for allowing oil to flow out from the respective oil passages 11a, 11b, 11c, and 11d through the end portions of the tubes 10a, And an inflow cap 25 provided at the other end of the tube 10a located on the uppermost layer among the plurality of tubes 10 and communicating with the outflow channel (not shown) (26) .

Therefore, the oil introduced into the inlet cap 25 flows into the respective oil passages 11a, 11b, 11c, and 11d while flowing along the inlet passages 30 as shown in Figs. 1 and 2 (Not shown) after the heat exchange with the cooling water flowing outside flows through the outlet cap 26.

2, the width (or diameter) of the inflow passage 30 is the same as that of each of the tubes 10a, 10b, 10c, and 10d, There is a problem that the oil introduced into the oil passage 30 is mostly introduced into the oil passage 11d of the lowermost tube 10d and the amount of the oil flowing into the oil passage of the upper tube decreases. The amount of oil flowing into the oil passages 11a, 11b, 11c, and 11d of the tubes 10a, 10b, 10c, and 10d is not uniform, and heat dissipation is inefficient .

1. Korean Patent Registration No. 0892111 (Registered on Mar. 31, 2009)

An object of the present invention is to provide an oil cooler that can keep the amount of oil flowing into an oil passage of each tube as even as possible.

According to an aspect of the present invention, there is provided an oil cooler comprising: a plurality of tubes each having an oil passage formed therein and stacked at intervals; An inflow passage communicating one end of each of the tubes to distribute the oil to the respective oil passages; And a distribution deviation reducing member provided in the inflow passage and reducing a distribution deviation of the amount of oil distributed to each of the oil passage.

The distribution deviation reducing member may have a plate shape and be inclined with respect to the longitudinal direction of the inflow passage.

The distribution deviation reducing member may be inclined in a direction in which the space of the inflow passage gradually decreases toward the rear end of the inflow passage with reference to the inflow direction of the oil.

The rear end of the distribution deviation reducing member may be joined to the inner wall of the lowermost tube among the plurality of tubes, with reference to the direction of inflow of the oil.

The rear end of the distribution deviation reducing member may be joined to the inner wall of the lowermost tube through brazing.

For example, the oil cooler according to the above-described embodiment of the present invention may be connected to the transmission for cooling the oil in the transmission.

As another example, the oil cooler according to the above-described embodiment of the present invention can be connected to the engine for cooling the oil of the engine.

As described above, the oil cooler according to the embodiment of the present invention can have the following effects.

According to the embodiment of the present invention, since the technical constitution including the plurality of tubes, the inflow channel, and the disparity reduction member is provided, the amount of oil flowing into the oil channel of each tube by the disparity reduction reducing member is maximized And the heat dissipation performance of the oil cooler can be enhanced.

Fig. 2 is an enlarged cross-sectional view of an oil passage side of a conventional oil cooler.
3 is a cross-sectional view schematically showing an oil cooler according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

3 is a cross-sectional view schematically showing an oil cooler according to an embodiment of the present invention.

The oil cooler 100 according to an embodiment of the present invention includes a plurality of tubes 110, an inflow passage 120, and a disparity reduction member 130, as shown in FIG. Hereinafter, each component will be described in detail with continued reference to Fig.

As shown in FIG. 3, the plurality of tubes 110 are constituent elements which form oil passages 111 inside each other and are stacked at a distance from each other. Therefore, the oil requiring heat dissipation passes through the oil passages 111a, 111b, 111c, and 111d, and cooling water passes between the tubes 110a, 110b, 110c, and 110d, The oil can be cooled in such a way that the oil having a high temperature heat source exchanges heat with the cooling water at a low temperature.

Furthermore, a pin 150 may be provided between each of the tubes 110a, 110b, 110c, and 110d to increase heat exchange efficiency.

3, the inlet flow path 120 communicates one end of each of the tubes 110a, 110b, 110c, and 110d to form oil passages 111a, 111b, 111c, and 111d ). ≪ / RTI > Specifically, the inflow channels 120 may be formed by passing through the tubes 110a, 110b, 110c, and 110d with the same diameter and forming the same center (see "L").

3, the distribution deviation reducing member 130 is disposed in the inflow passage 120 to distribute the amount of oil dispensed to the respective oil passages 111a, 111b, 111c, and 111d This is a component that reduces the deviation. Therefore, the distribution deviation reducing member 130 can keep the amount of the oil flowing into the oil passages 111a, 111b, 111c, and 111d of each tube 110 as even as possible.

Hereinafter, with reference to FIG. 3, the distribution deviation reducing member 130 will be described in more detail.

The distribution deviation reducing member 130 has a plate shape and may be inclined with respect to the longitudinal direction L of the inflow path 120. Therefore, the amount of oil flowing into each of the oil passages 111a, 111b, 111c, and 111d can be more uniformly controlled by adjusting the inclination amount of the distribution deviation reducing member 130. [

Further, the distribution deviation reducing member 130 may be inclined in a direction in which the space of the inflow passage 120 gradually decreases toward the rear end of the inflow passage 120, with reference to the inflow direction of the oil.

Therefore, as the space of the inflow passage 120 adjacent to the oil passage 111d of the lowest-layer tube 110d into which the oil is relatively inflow is narrowed, the amount of oil flowing into the oil passage 111d is relatively reduced The amount of oil flowing into the oil passage 111a becomes relatively large as the space of the oil passage 120 adjacent to the oil passage 111a of the uppermost layer tube 110a into which the oil is relatively inflow is widened, In this manner, the amount of oil introduced into each of the oil passages 111a, 111b, 111c, and 111d can be more uniformly maintained.

Further, the rearward end of the distribution deviation reducing member 130 can be joined to the inner wall of the lowermost tube 110d among the plurality of tubes 110, on the basis of the oil flowing direction. In particular, the rear end of the distribution deviation reducing member 130 can be joined to the inner wall of the lowermost layer tube 110d through brazing. For reference, reference numeral "B" indicates "brazed joint portion ".

Therefore, since the structural stiffness of the rear portion of the distribution deviation reducing member 130, in which the pressure resistance is weakest due to the oil flowing into the inflow passage 120, is improved through brazing, the pressure resistance against this portion can also be improved.

The oil cooler 100 according to an embodiment of the present invention may be used in connection with a transmission for cooling the oil of a transmission (not shown) or may be connected to an engine Can be connected and used.

As described above, the oil cooler 100 according to the embodiment of the present invention can have the following effects.

According to one embodiment of the present invention, since the technical constitution including the plurality of tubes 110, the inflow channel 120, and the disparity reduction member 130 is provided, the disparity reduction member 130 The amount of oil flowing into the oil passages 111a, 111b, 111c, and 111d of the tubes 110 can be maintained as even as possible and the heat radiation performance of the oil cooler 100 can be enhanced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
