Coolant Flow Control TRIZ Cases
- Variable Speed Fan Gear Arrangement for Agricultural Harvester Cooling
A mechanical variator decouples fan speed from engine rotation, reducing power consumption and noise while maintaining reliable thermal management.
- Vehicle Control Module Communication Loss Cooling Strategy
A vehicle control module maintains coolant pump operation during network faults by using stored target values and increased battery voltage.
- Pneumatically-Operated Cooling Pump Shutter Seal
A pneumatically-operated cooling pump uses a shutter mechanism with static seals to regulate coolant flow.
- Torque Converter Thermal Management for Cold Start
Restricting torque converter turbine motion during idle conditions transfers waste heat to cold components, reducing fuel consumption and carbon buildup.
- Bypass Valve Barrier Assembly External Port Design
An external barrier assembly regulates coolant flow through a bypass port, preventing pressure drops in main engine cooling passages.
- Construction Machine Cooling Structure Soundproofing
Shield member partitions air intake chamber to intercept direct sound, preventing leakage without enlarging installation space.
- Aerodynamic Shutter Control for Regenerative Braking
Dynamic shutter control reduces aerodynamic drag while regenerative braking recovers kinetic energy, balancing cooling needs against efficiency.
- Adjustable Shutter Ventilation for Genset Cooling Efficiency
Temperature sensors and controllers adjust ventilation shutters to reduce fan power consumption while maintaining engine cooling effectiveness.
- Cooling Water Control Apparatus Valve Failure Detection
A cooling water control apparatus manages heat transfer to isolate temperature variations for precise valve state monitoring.
- Wind Shielding Member for Blow-by Gas Connection Tube
A wind shielding member blocks cooling airflow from a blow-by gas connection tube, preventing liquid freezing in cold prime mover environments.
- Low Solidity Axial Fan Reduces Ram Air Resistance
Reducing fan solidity to under 40% lowers ram air resistance while maintaining static pressure for heavy duty truck engine cooling.
- Multi-mode Valve Assembly for Electric Vehicle Thermal Control
Segmented cooling loops with dynamic valves resolve the contradiction between precise temperature control and system complexity in electric vehicles.
- Convex Fan Shroud for Engine Cooling Airflow
Smooth convex walls minimize turbulence to increase airflow rates, resolving low-speed cooling inefficiencies in restrictive engine compartments.
- Magnetorheological Clutch for Variable Engine Coolant Pump Speed
An MRF clutch replaces fixed engine coupling with variable torque transfer, eliminating parasitic power losses from constant-speed pumps.
- Valve Device Sealing Disk Units for Compact Motor Vehicle Applications
Dual sealing disk units with overlapping flow openings enable precise fluid control in compact valve housings.
- Active Grille Shutter Control via Coolant Rate and Drag
Active grille shutters adjust opening based on coolant temperature rate of change to prevent engine overheating while minimizing aerodynamic drag.
- Vehicle Heat Exchanger Bimetal Valve Integration
Integrated bimetal valve in stacked plates controls fluid flow, reducing component count and assembly complexity for vehicle thermal management.
