Propulsion Cooling TRIZ Cases
- Vehicle Heat Exchanger Airflow Flaps for Cooling Backup Paths
Dual flaps create independent airflow paths to the vehicle heat exchanger, preserving cooling if shutters fail while limiting drag.
- Grille Shutter Lamella Mounting for Easy Replacement
A mounting pin, C-shaped arm, and coupling link let grille shutter lamellas be installed and replaced without bending damage.
- Grille Shutter Fins With Collision Drop-Off for Cooling Airflow
A passive drop-off fin mechanism keeps grille opening area available during collisions, preserving vehicle cooling airflow without a center pillar.
- Passive PTO Cooling Through Axle Housing Heat Conduction
A passive heat-conducting path moves PTO heat into the axle chamber, improving stationary cooling without pumps, added complexity, or extra maintenance.
- Brake Duct Backflow Plate for Radiator and Brake Cooling
A backflow suppression plate in the brake duct redirects hot air away from the radiator while preserving brake cooling during travel.
