Vehicle Reservoir Tank Support for Coolant Level Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During high-speed turning or rapid acceleration/deceleration of a vehicle, the coolant level in the reservoir tank becomes deviated, leading to air bubbles mixing into the cooling circuit, which deteriorates cooling efficiency.
Innovation Solution
A support mechanism for the reservoir tank that includes a displacement device allowing the tank's attitude to change based on predicted acceleration vectors, using a combination of pivotable actuators to maintain the coolant level parallel to the tank's bottom wall, thereby preventing air bubbles from entering the cooling circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reservoir tank is fixed in a vertical position, then the structure is simple and stable, but air bubbles enter the cooling circuit during non-gravitational acceleration
Solution Approach 1:
The reservoir tank is made dynamically adjustable in attitude through the displacement device with first and second actuators. The tank can change its orientation relative to the vehicle body to maintain the coolant port submerged during various acceleration conditions, transforming from a static fixed-position structure to a dynamic adaptive structure.
Solution Approach 2:
The system uses self-service by utilizing the vehicle's own acceleration data and predicted acceleration information to automatically adjust the reservoir tank's attitude. The controller receives acceleration signals and predicted acceleration data, then autonomously controls the displacement device to position the tank appropriately without requiring external intervention.
2Reliability
If the reservoir tank attitude is adjusted using actuators, then air bubble intermingling is suppressed, but the device complexity increases
Solution Approach 1:
The displacement device is segmented into two independent actuators: a first actuator that pivots about a vertical axis and a second actuator that pivots about an axis orthogonal to the vertical axis. This segmentation allows each actuator to handle specific orientation adjustments independently, making the complex attitude control task more manageable and modular.
Solution Approach 2:
The reservoir tank is made dynamically adjustable in attitude through the displacement device with first and second actuators. The tank can change its orientation relative to the vehicle body to maintain the coolant port submerged during various acceleration conditions, transforming from a static fixed-position structure to a dynamic adaptive structure.
3Quantity of substance
If the coolant port is positioned at the bottom wall, then coolant storage is efficient, but the port becomes exposed during acceleration causing air bubbles
Solution Approach 1:
The reservoir tank's attitude is dynamically adjusted using the displacement device to maintain the coolant port submerged during acceleration. By actively changing the tank's orientation based on detected and predicted acceleration, the system ensures the port remains below the coolant surface while preserving bottom-wall positioning for efficient storage.
Solution Approach 2:
The controller uses feedback from acceleration signals and predicted acceleration data to continuously adjust the reservoir tank's attitude. This closed-loop control ensures the coolant port remains properly submerged during various driving conditions, preventing air bubble entry while maintaining efficient coolant storage.
