Manifold Baffle Design for Dual Fluid Loop Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrified vehicles require efficient thermal management systems with multiple independent fluid loops, but existing systems are complex due to separate fluid supply reservoirs for each loop, leading to increased complexity and potential inefficiencies in temperature control.
Innovation Solution
A manifold with a baffle and a common reservoir that gravity-feeds fluid to separate fluid loops, allowing for independent temperature control of vehicle components while reducing system complexity by using a single reservoir for both loops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate fluid supply reservoirs are used for each fluid loop, then temperature control independence is improved, but system complexity increases
Solution Approach 1:
The manifold is segmented into multiple regions using baffles, with each region serving a separate fluid loop. This allows a single reservoir to function as multiple independent supply sources, maintaining temperature control independence while reducing system complexity by eliminating the need for separate physical reservoirs for each loop
2Device complexity
If a single common reservoir is used for multiple fluid loops, then system complexity is reduced, but temperature separation between loops may be compromised
Solution Approach 1:
The manifold is divided into distinct regions using baffles, creating separate fluid pathways for each fluid loop. This segmentation allows a single common reservoir to supply multiple loops while maintaining temperature separation, as each loop receives fluid through its dedicated region and pathway
Solution Approach 2:
The baffles act as intermediaries that physically separate the fluid pathways within the manifold while allowing the common reservoir to supply all loops. This intermediary structure enables both cost reduction through a single reservoir and temperature separation through defined fluid pathways
3Temperature
If baffles are used to divide manifold regions, then temperature separation is improved, but manufacturing complexity increases
Solution Approach 1:
The baffles serve multiple functions: they divide the manifold into temperature-separated regions, guide fluid flow along defined pathways, and can be integrated with the manifold as a single manufactured component. This multi-functionality justifies the manufacturing complexity by delivering critical thermal management performance

AI summary
An exemplary assembly includes, among other things, a manifold having an interior area with a baffle, and a reservoir. The baffle divides a portion of the interior area into a first region that is part of a first fluid loop of a vehicle, and a second region that is part of a separate, second fluid loop of the vehicle. The reservoir is configured to hold a supply of liquid that is in fluid communication with both the first and second regions. An exemplary method includes, among other things, communicating a fluid from a supply within a reservoir to both a first and a second region within an interior area of a manifold. The first region is part of a first fluid loop of a vehicle. The second region is part of a separate second fluid loop of the vehicle.
