Transformers/Inductances Cooling TRIZ Cases
- Wind Turbine Transformer Pressure Relief and Decompression Chamber
A wind turbine transformer arrangement uses a pressure release tube to transfer excess gas into an oil-tight decompression chamber.
- High-Voltage Transformer with Hollow Tubular Insulator
Hollow tubular insulation nests windings in oil, reducing leakage reactance and volume while maintaining dielectric strength.
- Membrane Screw for Transformer Oil Gas Separation
A membrane screw integrates a permeable structure to separate gases from transformer oil directly within the tank.
- Magnetic Part Core Fixation via Recessed Support Member
A magnetic part design uses a recessed support member to press core column portions directly against the substrate.
- Vertical Airflow Cooling for Indoor Transformer Footprint Reduction
An air transfer unit directs airflow vertically through cooling fins, reducing indoor transformer footprint while maintaining effective heat dissipation.
- Transformer Arrangement With Orthogonal Windings And Thermal Shell
An orthogonal winding configuration distributes magnetic flux across three axes while an aluminum thermal shell conducts heat away from the core.
- Air Dehydrating Breather Assembly with Regenerable Silica Gel
A breather assembly uses regenerable silica gel tanks to provide dehumidified air for electrical device oil expansion vessels.
- Vapor-Phase Drying of Transformer Insulation Using Multi-Stage Solvent Injection
Multi-stage solvent injection creates saturated vapor jets that heat solid insulation in electrical devices.
- Coil Device Bobbin Retainer for Flat Coil Positioning
A coil device bobbin uses a retainer member to secure flat coils within accommodation grooves.
- In-Vehicle Cooling Device With Overlapping Pipes
Vertical and horizontal cooling pipes overlap orthogonally to increase heat exchange surface area without expanding the installation region.
- Transformer Desiccant Regeneration via Temperature Second Derivative
A temperature signal analysis method determines optimal desiccant regeneration timing in transformer breathers using periodic sensor data.
- Dual Cooling Fan Wireless Charger with Volute Partition
Dual cooling fans separated by a volute-shaped partition guide air through openings to eliminate uneven flow during high-output charging.
- Integrated Magnetic Element for On-Board Charger Volume Reduction
An integrated magnetic element combines resonant inductor and transformer windings on a unified core to reduce volume and weight.
- Transformer Oil Cooling Flow Monitoring via Temperature Differential
Replacing mechanical flowmeters with temperature differential monitoring ensures reliable fluid detection at low temperatures and high viscosity.
- Metallic Spacers for Induction Core Cooling
Metallic spacers in induction cores conduct heat from stacked metal sheets to cooling fluid, resolving low thermal conductivity and reduced fullness factor.
- Measuring Device Coil Carrier Thermal Expansion Management
A coil carrier positions a measuring device coil radially outside the sensing element to manage thermal expansion in high temperature rolling mill environments.
- Fatty Acid Ester Dielectric Fluid for High Breakdown Voltage
Transesterified vegetable oil blends achieve high breakdown voltage while maintaining biodegradability without toxic additives.
- Static Induction Cooling via Time-Varying Flow Curves
A pumping system applies a time-varying flow rate curve to static induction cooling ducts, eliminating stagnant fluid zones and reducing hotspot formation.
