Bench concept / physical testing planned
Direct-to-Chip Cooling Bench.
Turning a thermal measurement question into an instrumented test concept.
Objective
Connect thermal theory, hardware, instrumentation, and data analysis through a single-branch liquid-cooling validation bench concept using a commercial cold plate.
Engineering
The plan centers on coolant energy balance, pressure drop, thermal resistance, hydraulic power, repeatability, and measurement uncertainty. Thermal resistance requires a clearly defined temperature reference and measurement boundary.
Design work
Planned measurements include coolant inlet and outlet temperatures, flow rate, pressure difference, and heater voltage and current. These would support comparisons across controlled heat-input and coolant-flow conditions.
Representative planning ranges are 100–400 W and 0.5–2.0 L/min, also used in synthetic software fixtures. Final operating conditions depend on equipment selection and review.
Verification plan
Use defined sensor locations, calibration records, repeated tests, and uncertainty estimates to compare analytical predictions with future measurements. Hardware and test conditions still require review before physical implementation.
Current status
The independent bench is a design concept with companion analysis software implemented. Assembly and physical testing are planned.
Current learning focus
Turning a desired measurement into explicit sensor locations, definitions, uncertainty sources, and repeatable procedures.
