Abstract

An oil cooler includes a plurality of tubes having both ends each fixed to a pair of header tanks in the length direction to form channels. The oil cooler further includes heat radiation fins, a first flange having an inlet pipe and an outlet pipe each coupled thereto in the length direction, a second flange coupled to any one of the header tanks in the length direction, and a bypass valve installed between the first flange and the second flange. The fixing bolts bolt the first flange, the bypass valve, and the second flange together while penetrating through the first flange, the bypass valve, and the second flange in the length direction.

First claim

What is claimed is:

1. An oil cooler comprising:
a pair of header tanks spaced from each other along a length of the oil cooler;
a plurality of tubes extending between and in fluid communication with the pair of header tanks;
a plurality of heat radiation fins interposed between the plurality of tubes;
a first flange having an inlet pipe and an outlet pipe coupled thereto and extending outwardly therefrom in a direction parallel to the length of the oil cooler, each of the inlet pipe and the outlet pipe in fluid communication with the pair of header tanks;
a second flange coupled to one of the pair of header tanks;
a bypass valve disposed intermediate the first flange and the second flange; and
a fixing bolt coupling the first flange, the bypass valve, and the second flange to each other and extending through the first flange, the bypass valve, and the second flange in the direction parallel to the length of the oil cooler.

2. The oil cooler of claim 1 , the first flange having a first insertion part and a second insertion part formed therein, the first insertion part receiving the inlet pipe and the second insertion part receiving the outlet pipe, the second flange having a first perforation part and a second perforation part formed therein and in fluid communication with the inlet pipe, the outlet pipe, and the pair of header tanks, and the bypass valve having a first channel providing fluid communication between the first insertion part and the first perforation part and a second channel providing fluid communication between the second insertion part and the second perforation part.

3. The oil cooler of claim 2 , the bypass valve including a bypass channel providing fluid communication between the first channel and the second channel.

4. The oil cooler of claim 3 , the inlet pipe receiving an oil and the bypass valve selectively closing one of the first channel and the bypass channel dependent on a temperature of the oil.

5. The oil cooler of claim 2 , further comprising a plurality of connectors, a first one of the plurality of connectors disposed intermediate the first channel and the first insertion part, a second one of the plurality of connectors intermediate the first channel and the first perforation part, a third one of the plurality of connectors disposed intermediate the second channel and the second insertion part, and a fourth one of the plurality of connectors disposed intermediate the second channel and the second perforation part.

6. The oil cooler of claim 5 , each of the plurality of connectors including an extension ring formed on and protruding outwardly from an outer peripheral surface thereof.

7. The oil cooler of claim 6 , further comprising a plurality of O-rings, each of the plurality of O-rings disposed on the outer peripheral surface of one of the plurality of connectors.

8. The oil cooler of claim 7 , each of the plurality of O-rings contacting one of the extension rings of the plurality of connectors.

9. The oil cooler of claim 1 , the bypass valve including a valve protrusion extending outwardly therefrom in a direction parallel to a width of the oil cooler, the first flange including a first flange protrusion extending outwardly therefrom adjacent a first end of the valve protrusion and the second flange including a second flange protrusion extending outwardly therefrom adjacent a second end of the valve protrusion.

10. The oil cooler of claim 9 , the fixing bolt extending through the valve protrusion, the first flange protrusion, and the second flange protrusion in the direction parallel to the length of the oil cooler.

11. The oil cooler of claim 10 , the bypass valve including a plurality of valve protrusions extending outwardly therefrom, the first flange including a plurality of first flange protrusions extending outwardly therefrom, the second flange including a plurality of second flange protrusions extending outwardly therefrom, and the oil cooler comprising a plurality of fixing bolts, each of the fixing bolts extending through one of the plurality of valve protrusions, one of the plurality of first flange protrusions, and one of the plurality of second flange protrusions in the direction parallel to the length of the oil cooler.

12. The oil cooler of claim 9 , a plurality of valve protrusions extending outwardly from the bypass valve, the plurality of valve protrusions spaced from each other in a direction parallel to a height of the oil cooler.

13. The oil cooler of claim 9 , a plurality of valve protrusions extending outwardly from opposing sides of the bypass valve in the direction parallel to the width of the oil cooler.

14. An oil cooler comprising:
a pair of header tanks spaced from each other along a length of the oil cooler;
a plurality of tubes extending between and in fluid communication with the pair of header tanks;
a plurality of heat radiation fins interposed between the plurality of tubes;
a first flange having a first insertion part and a second insertion part formed therein, the first insertion part receiving an inlet pipe and the second insertion part receiving an outlet pipe, the inlet pipe and the outlet pipe extending outwardly from the first flange in a direction parallel to the length of the oil cooler, each of the inlet pipe and the outlet pipe in fluid communication with the pair of header tanks;
a second flange coupled to one of the pair of header tank and having a first perforation part and a second perforation part formed therein, the first perforation part providing fluid communication between the inlet pipe and the pair of header tanks and the second perforation part providing fluid communication between the pair of header tanks and the outlet pipe;
a bypass valve disposed intermediate the first flange and the second flange, the bypass valve having a first channel and a second channel formed therein, the first channel providing fluid communication between the first insertion part and the first perforation part and the second channel providing fluid communication between the second insertion part and the second perforation part; and
a fixing bolt coupling the first flange, the bypass valve, and the second flange to each other and extending through the first flange, the bypass valve, and the second flange in the direction parallel to the length of the oil cooler.

15. The oil cooler of claim 14 , the bypass valve including a bypass channel providing fluid communication between the first channel and the second channel, the inlet pipe receiving an oil and the bypass valve selectively closing one of the first channel and the bypass channel dependent on a temperature of the oil.

16. The oil cooler of claim 14 , the bypass valve including a valve protrusion extending outwardly therefrom in a direction parallel to a width of the oil cooler, the first flange including a first flange protrusion extending outwardly therefrom adjacent a first end of the valve protrusion, and the second flange including a second flange protrusion extending outwardly therefrom adjacent a second end of the valve protrusion.

17. The oil cooler of claim 16 , the fixing bolt extending through the valve protrusion, the first flange protrusion, and the second flange protrusion in the direction parallel to the length of the oil cooler.

18. A method of cooling oil in an oil cooler of an automobile, comprising the steps of:
