Transformers/Inductances Cooling TRIZ Cases

Internal coolant flow through a closed ferromagnetic core cools the windings directly, cutting inductor size, copper use, and AC loss.

Solid-state welded plugs seal winding cooling channel holes without solder, preventing corrosion and leakage in welding transformers.

A narrowed longitudinal channel and bypass path redistribute transformer oil, cutting recirculation and improving cooling at higher pump flow rates.

Multiple stacked boards and interleaved cooling bodies shorten heat paths, improving thermal dissipation without enlarging the converter footprint.

A thermally conductive insulating support member improves vehicle coil cooling through the housing without adding separate cooling weight.

Sliding air flow passages let dust be cleaned from the cooler edge side without blocking airflow, helping maintain vehicle transformer cooling.

Potting-free channels through toroidal cores let motor phase conductors pass directly, simplifying filter assembly, retrofitting, and heat dissipation.

Heat-dissipating holes in a mold transformer insulator conduct core heat outward, improving X-ray generator stability and downsizing.

Expandable heat-exchanger panels cool a subsea transformer station while absorbing coolant pressure and volume changes to simplify the system.

A shared pump station and heat dissipation unit cool generator, converter, transformer, and shaft circuits with less piping complexity and fewer failures.

An integral tube coil uses laser-cut helical gaps and seamless contact regions to lower resistance, thermal stress, and failure risk in small coils.

A radial fan and vaned air scoop turn turbulent airflow into uniform axial cooling over the motor housing heat sink and controller.
