Abstract

Disclosed herein is a heat exchanger in a vehicle including a supply manifold which supplies fluid introduced from the outside while distributing the fluid to first and second cooling units. The first and second cooling units cool the fluid supplied from the supply manifold by heat exchange action. A first return manifold collects and discharges the fluid discharged from the first cooling unit and a second return manifold collects and discharges the fluid discharged from the second cooling unit.

First claim

a first return manifold in fluid communication with the first cooling unit and configured to receive and discharge the transmission fluid from the first cooling unit; and
a second return manifold in fluid communication with the second cooling unit and configured to receive and discharge the transmission fluid from the second cooling unit, wherein the supply manifold is disposed intermediate the first return manifold and the second return manifold.

2. The heat exchanger according to claim 1 , wherein the supply manifold is disposed intermediate the first cooling unit and the second cooling unit.

3. The heat exchanger according to claim 1 , wherein the first cooling unit and the second cooling unit extend from the supply manifold in opposite directions from each other.

4. The heat exchanger according to claim 1 , wherein the first cooling unit includes a plurality of first cooling passages configured for conveying the transmission fluid through the first cooling unit and a plurality of first cooling fins contacting the first cooling passages and configured to facilitate heat exchange communication between the transmission fluid in the first cooling passages and the air, and wherein the second cooling unit includes a plurality of second cooling passages configured for conveying the transmission fluid through the second cooling unit and a plurality of second cooling fins contacting the second cooling passages and configured to facilitate heat exchange communication between the transmission fluid in the second cooling passages and the air.

5. The heat exchanger according to claim 4 , wherein the first cooling passages and the second cooling passages are disposed substantially perpendicular to a longitudinal direction of the supply manifold, wherein a direction of the transmission fluid through the first cooling passages is opposite a direction of the transmission fluid conveyed through the second cooling passages.

6. The heat exchanger according to claim 1 , further comprising a supply passage in fluid communication with and intermediate the transmission of the vehicle and the supply manifold.

7. The heat exchanger according to claim 1 , further comprising a bypass passage disposed intermediate and in fluid communication with the supply manifold and the first return manifold, the bypass passage bypassing the first cooling unit.

8. The heat exchanger according to claim 7 , further comprising a first opening and closing unit in fluid communication with the bypass passage and adjustably controlling an amount of the transmission fluid conveyed from the bypass passage to the first return manifold.

9. The heat exchanger according to claim 7 , further comprising a second opening and closing unit in fluid communication with the second return manifold and adjustably controlling an amount of the transmission fluid discharged from the second return manifold.

10. The heat exchanger according to claim 7 , wherein the bypass passage is fixedly coupled to the supply manifold and the first return manifold.

11. The heat exchanger according to claim 1 , further comprising a first discharge passage in fluid communication with and disposed downstream from the first return manifold and a second discharge passage in fluid communication with and disposed downstream from the second return manifold.
