Parallel Cooling Tank With Dented Wall For Engine Room
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling devices for vehicles with electric power control systems face challenges in miniaturizing the engine room due to the limited space for the cooling water tank, which also fails to effectively suppress the temperature increase of thick wiring connected to the electric power control device, making it difficult to lower the engine hood and efficiently utilize space.
Innovation Solution
A cooling device design where the cooling water tank is arranged in parallel near the electric power control device with a dented side surface wall matching the wiring's external shape, allowing close coverage and effective cooling, while maintaining a predetermined interval to prevent interference and abrasion, and utilizing fixing parts to secure the tank and wiring in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cooling water tank is disposed on the electric power control device, then space inside the engine room is effectively utilized, but the engine hood cannot be lowered
Solution Approach 1:
The cooling water tank is repositioned from a vertical arrangement (on top of the electric power control device) to a horizontal arrangement (in parallel beside it). This dimensional change allows the tank to occupy lateral space rather than vertical space, enabling the engine hood to be lowered while still accommodating the cooling water tank within the engine room's lateral boundaries.
2Length of stationary object
If the cooling water tank is arranged in parallel near the electric power control device to lower the engine hood, then engine hood height is reduced, but the thick wiring prevents close arrangement and space miniaturization
Solution Approach 1:
The dented side surface wall is created locally on the cooling water tank at the position where the wiring passes. This localized structural modification allows the tank wall to closely follow the wiring's external shape, maximizing space utilization in the specific region occupied by the wiring without affecting the overall tank dimensions or requiring additional clearance throughout the entire tank structure.
3Length of stationary object
If the cooling water tank is arranged in parallel near the electric power control device, then engine hood height is reduced, but the wiring temperature increase cannot be suppressed
Solution Approach 1:
The wiring is nested within the space created by the dented side surface wall of the cooling water tank. The tank's dented wall contours wrap around the wiring, allowing the cooling water tank to closely adjoin the wiring in parallel arrangement. This nested configuration enables the cooling water tank to effectively cool the wiring through thermal conduction while maintaining the lowered engine hood height.
