Coolant Flow Control TRIZ Cases

A reversible air-guiding channel and radial fan improve EV battery and motor cooling at low speed while cutting fan noise and power use.

Integrated fins between grille flaps block external projections from reaching the cooling module without adding a separate protective grille.

A breakaway marking element stays visible on the tube connector, letting engineers verify the installed flow restrictor size after assembly.

A temperature-triggered shielding screen blocks freezing airflow to the radiator cooling package, preventing ice buildup without manual clearing.

A suspended rear element synchronizes non-parallel air inlet flaps, preserving sealing, airflow control, aerodynamics, and heat exchanger efficiency.

Real-time vane positioning compares drag-related energy loss with recovery gains to improve vehicle efficiency and extend recovery operation.

A heat exchange unit uses battery-cooling refrigerant to lower motor cooling oil temperature, improving motor output and component life.

One-way valves isolate cooling circuits to stop fluid mixing, improve temperature accuracy, and protect pump life in vehicle heat management.

Reversing the cooling fan clears dust, dirt, ice, and snow from tracked vehicle cooling surfaces to sustain heat dissipation.

A combustion-driven turbine powers heating and air compression to maintain engine temperature and brake pressure without battery drain or engine idling.

A pressure-adjusting flow path in a shared cooling manifold balances battery and motor loop pressure to stabilize pump flow and cooling capacity.

An integrated pressure-adjusting flow path in the cooling manifold stabilizes pump flow and cooling capacity without an external expansion kettle.

Soft two-shot molded flaps and a stepped frame wall improve grille shutter sealing, reduce rattle, and avoid sudden actuator torque spikes.

A flush grille-mounted flap structure cuts step-induced wind noise and drag while improving airflow control and fuel efficiency.

Belt-linked winding shafts synchronize two airflow curtains, cutting torque demand and avoiding jamming in vehicle heat exchanger control.

A roll-up covering body clears the cooling-module opening when idle, cutting pressure loss while tangential airflow improves heat exchange uniformity.

Integrated coolant bypass ports avoid unnecessary refrigerant heat exchange and remove the manifold to shrink cooling circuit size.

Integrated tank shells form flow channels and valve housing to cut parts, simplify production, and save space in vehicle liquid systems.

Sensors compare actual and nominal valve-body rotation to detect misalignment early and prevent multi-way valve mechanical failure.

Load-based control loops set target inlet coolant temperature and adjust valves to prevent genset temperature oscillation and overshoot.

A separate auxiliary motor and planetary gearing add failsafe repositioning to vehicle air stream elements without increasing actuator size.

A pin-and-groove actuator drives two vehicle air flow closures asynchronously, splitting wind loads while keeping the mechanism compact and actuator forces low.

One-way valves and separate coolant circuits stop fluid mixing and gas buildup, improving temperature control and heat exchange in vehicle systems.

A single actuator, gear train, and square-shaft lever drive move multiple vehicle air-passage closures together while reducing drive count, force demand, and tilt.

A tangential fan with guide elements spreads airflow evenly across a vehicle heat exchanger while reducing blockage and packaging bulk.
