Relay Ventilation/Cooling/Heating TRIZ Cases
- Relay Contact Chamber Pressure Relief for Arc-Sealed Safety
A break-open pressure relief valve keeps the relay contact chamber sealed for arc extinction, then vents excess gas to prevent explosion.
- Pressure-Relief Relay Structure for Sealed Contact Chamber Explosion Risk
A break-open pressure relief valve vents excess gas from a sealed relay contact chamber before overload or short-circuit pressure causes explosion.
- Relay Contact Chamber Pressure Relief for Arc-Sealed DC Switching
A break-open pressure relief valve vents overpressure from a sealed relay contact chamber, preventing explosion while preserving arc extinguishing.
- Relay Pressure Relief Valve Assembly for Sealed Contact Chambers
A break-open valve on the relay yoke plate releases excess gas from a sealed contact chamber before fault pressure can cause explosion.
- Relay Bus Bar Layout for Wire Access and Heat Dissipation
An obliquely upward relay connector and inclined bus bar create wire access without raising the relay or weakening heat transfer.
- Contactor Heat Transfer Assembly for Higher Current Capacity
A heat transfer assembly cools fixed contacts through conduction and coolant flow, raising contactor current capacity without overheating.
- Switchable Contact Cooling for Higher Current Capacity
A separate heat-dissipating path moves heat outside the housing, raising current capacity without enlarging conductor cross-sections.
- Electromagnetic Relay Heat Dissipation Without Size Increase
Separate external heat dissipation members cool fixed terminals in high-current relays without enlarging the housing or raising substrate heat.
- Electromagnetic Relay Venting Structure for Arc Re-Ignition Control
A base gas passage and inflow space vent hot arc gas away from relay contacts, helping maintain insulation and prevent re-ignition.
- Electromagnetic Relay Cooling to Prevent Contact Freezing
A temperature-triggered cooler shifts condensation to the relay terminal base, preventing ice at contacts and avoiding conduction failure.
- Relay Device Inner Space Segmentation for Heat Management
Segmenting the relay cover isolates the heat-generating coil from sensitive contacts, resolving thermal risks during miniaturization.
- Electrical Switching Component Blast Venting Design
A venting system directs electrical switching blasts through a chassis passage into a diverting space.
