Cooling/Ventillation Arrangement TRIZ Cases

Asymmetric outlet port placement in a motor coolant branch balances flow in unequal-length channels, improving cooling uniformity without larger pumps.

A larger outlet port in the longer coolant path balances flow, improves motor cooling uniformity, and cuts pressure loss.

Tangential coolant flow spins a distribution element to spread cooling around the machine, enabling uniform heat dissipation even at standstill.

A stator-mounted cooling surface and refrigerant circuit improve rotor convection cooling and recover heat without relying on ambient air.

Varying channel cross-sections balances coolant flow in unequal motor passages, improving cooling uniformity while limiting pressure loss.

Bore extensions and sealing rings isolate stator coolant from the rotor cavity, cutting drag losses without adding motor space.

Fiber bodies in a spiral coolant groove generate turbulence to improve rotating machine cooling while limiting pressure loss.

Inclined cooling-ring orifices direct fluid onto coil ends for more uniform electric machine cooling even at low inlet pressure.

Parallel cooling-water passages split flow across machine regions to limit temperature irregularities and keep the rotating electric machine evenly cooled.

Liquid coolant is directed onto stator wire ends to remove motor hot spots, while an accumulator tank vents dissolved gas for reliable cooling.

Radially nested inner and outer bus bars cut stator axial length and footprint while preserving stable winding lead connections and cooling.

Resin placed between stator windings and facing the propeller improves coil heat transfer and uses airflow to cool a compact brushless motor.

Insulated thermal conductors pull heat from motor coils while blocking eddy-current paths that would otherwise add heat and reduce efficiency.

A common first cover integrates air vent and drain holes, simplifying motor cooling-jacket housings across different stator lengths.

A common motor cover integrates vent and drain holes, simplifying refrigerant-path housings across different stator lengths.

A heat dissipator routed behind the stator improves linear motor cooling while limiting moving body length and thermal deformation.

Heat-absorptive fluid cools the integrated actuator housing and drive mount to prevent electrical drive overheating in injection molding.

A ring-segment housing groove and cooling openings direct fluid onto the stator, improving axial flux motor cooling in compact e-axle layouts.

Angled stator-mounted baffles redirect airflow to under-cooled end windings, reducing hotspots, winding aging, and excess cooling power.

An integrated stator sleeve uses oil and water cooling channels plus a compensating chamber to save space while preventing oil contamination.

An asymmetric downward outlet hood redirects hot motor exhaust below the bogie to cut recirculation and protect nearby traction motor components.

A circumferential guide redirects cooling fluid around winding heads to keep it out of the air gap and cut drag torque losses.

Balanced sealing forces reduce stress on thin can walls, improving pressure resistance, sealing reliability, and power density.

A meandering oil passage between wedge-shaped and corrugated walls boosts oil turbulence and heat transfer for better stator cooling.

Integrated inspection caps and a continuous cooling coil solve sand-removal and alignment bottlenecks in rotating electric machine casings.

A spiral housing flow path widens then narrows to eliminate uncooled circumferential zones when refrigerant ports are far apart.

Individual non-magnetic thermal bridge elements conduct heat from stator windings to the housing while limiting flux leakage and eddy currents.
