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.
