Cooling/Ventillation Arrangement TRIZ Cases

Wave-shaped impressions on the fan cover increase stiffness and reduce noise by shifting natural oscillation frequencies away from operating ranges.

Varying coil cross-sectional areas radiates heat from the center to ends, reducing energy loss and improving motor thermal efficiency.

Segmented air paths channel cooling currents into the motor interior, preventing coil damage and maintaining performance in high temperatures.

A motor housing uses a segmented air guiding shell to direct cooling airflow through internal inlet holes for heat dissipation.

Segmented cooling jacket uses rotatable socket-spigot joints to adapt to motor contours, enabling selective unit replacement.

Segmented dual-fan design directs airflow through coil support openings to dissipate heat from rear-mounted electronics.

Integrating an annular groove and cover plate into the housing eliminates complex sealing components, resolving airtightness versus productivity trade-offs.

Segmented ventilation passages in rotor coils optimize width ratios to resolve inadequate heat dissipation and insufficient cooling effects.

Heat insulating unit separates low temperature gas flow from casing to reduce installation area while maintaining cooling efficiency.

Symmetric refrigerant supply ports target stator coil corners to ensure uniform cooling across rotating electric machine windings.

A cooling frame circulates liquid coolant through divided passages to cool internal oil and gas media within a rotating electric machine.
