Firewall-Integrated Coolant Reservoir for Space and Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle coolant tanks occupy significant space in the engine compartment and are difficult to access, especially in larger vehicles, requiring multiple tanks and causing plumbing and attachment issues.
Innovation Solution
A coolant reservoir integrated with the vehicle's firewall as a structural component, providing support for other components and featuring a fill port accessible without hood modification, a visible fluid level indicator, and a deaeration baffle to maintain fluid stability, even when the vehicle is tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional separate coolant tank is used, then coolant storage function is provided, but engine compartment space is occupied and accessibility is limited
Solution Approach 1:
The coolant tank is merged with the firewall structure to form an integrated assembly. The tank becomes part of the firewall itself, eliminating the need for a separate standalone tank while maintaining coolant storage capacity. This integration improves space utilization and accessibility in the engine compartment.
2Quantity of substance
If multiple coolant tanks are used to accommodate larger engines, then sufficient coolant capacity is achieved, but plumbing complexity and attachment issues increase
Solution Approach 1:
The firewall-integrated tank design provides a universal solution that can accommodate different coolant capacities by varying the tank size or configuration within the same integrated structure. This multi-functional approach eliminates the need for multiple separate tanks while maintaining sufficient coolant capacity for larger engines.
3Area of stationary object
If the tank is integrated with the firewall, then space is optimized and structural support is provided, but manufacturing complexity increases
Solution Approach 1:
The integrated firewall-tank assembly is divided into separate manufacturable components that are assembled together. The firewall and tank can be manufactured separately using standard processes and then joined through welding or other joining methods, reducing manufacturing complexity while maintaining the space-saving integrated design.

AI summary
One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.
