Cooling plate failures should be reviewed as a system problem involving the component, water circuit, mounting interface and operating history.
Common Failure Drivers
Leakage or distortion can result from more than one contributing factor.
- Blocked or uneven water flow can create local overheating.
- Thermal cycling, restraint and unsuitable wall transitions can concentrate stress.
- Erosion, corrosion, water quality and weld defects may reduce remaining wall thickness.
Replacement Review
A replacement RFQ should include evidence from the failed component and current equipment.
- Provide photographs, leak location, service time and operating changes.
- Verify dimensions from both the drawing and the actual mounting interface.
- Review whether channels, connections, weld details or material should change.
Inspection and Prevention
Inspection should target the known risk rather than rely on a generic certificate list.
- Pressure or leak testing verifies the completed water circuit.
- PT may support surface inspection of suitable welds and machined areas.
- Dimensional and connection checks reduce installation mismatch.
