Oil Cooler Partition Wall Design for Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil cooler designs require a separate plate component with a groove to prevent oil from flowing back into the transmission case without passing through the cooler, which complicates the configuration and reduces the amount of oil that can flow through the heat exchange unit.
Innovation Solution
An oil cooler apparatus with a base plate that includes an inflow port facing the oil outlet on the transmission case, a discharge port, and a partition wall on the facing surface to separate the inflow and discharge ports, allowing a larger amount of fluid to flow into the heat exchange unit without the need for a separate plate component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate plate component with a groove is used to prevent oil from flowing back into the transmission case, then oil flow control is improved, but device complexity increases
Solution Approach 1:
The patent merges the separate plate component with the base plate of the heat exchange apparatus. The partition wall is integrated into the base plate structure, eliminating the need for a separate plate component while maintaining the function of guiding oil flow and preventing direct communication between inlet and outlet ports. This integration resolves the contradiction by reducing device complexity while preserving oil flow control reliability.
2Reliability
If a separate plate component is used to control oil flow, then oil flow direction is improved, but the amount of oil that can flow through the heat exchange unit decreases
Solution Approach 1:
The patent transitions from using a separate plate component (one-dimensional addition) to integrating the partition wall directly into the base plate structure (two-dimensional integration). This dimensional change allows the partition wall to be formed as part of the base plate's facing surface, eliminating the need for additional components and increasing the available flow area for oil to pass through the heat exchange unit while maintaining proper flow direction control.
3Reliability
If a separate plate component is added to prevent oil bypass, then oil cooling reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the partition wall function with the base plate manufacturing process. By forming the partition wall as an integral part of the base plate structure, the invention eliminates the need for separate manufacturing and assembly of a plate component. This merging reduces manufacturing steps, lowers production costs, and simplifies assembly while maintaining the reliability of oil cooling through proper flow direction control.

AI summary
An apparatus includes a case including a heat exchange unit; an inflow port through which a fluid flows into the heat exchange unit; and a discharge port through which the fluid is discharged from the heat exchange unit. In the case, the inflow port and the discharge port are opened in a facing surface facing a component to which the apparatus is assembled, the inflow port is disposed to face a fluid outlet of the component, and a partition wall that separates an inflow port side and a discharge port side is provided on the facing surface.
