Cold plate performance tester

23 January 2013 Test & Measurement

The iFLOW-200 system from Advanced Thermal Solutions assesses the thermal and hydraulic characteristics of cold plates in electronics cooling. It measures the coolant’s temperature at inlet and outlet, fluid flow rate and pressure drop, and surface temperature.

The machine can be used to simulate a wide range of conditions to optimise a cold plate’s performance before it is commercialised, or prior to its use in an actual application. It measures coolant temperature from 0-70°C with an accuracy of ±1°C.

Differential pressure of the coolant in the cold plate is measured up to 103 000 Pa (15 psi). Distilled water is the reference coolant. For test comparisons, the system’s coolingVIEW software can also calculate thermal resistance and pressure drop as a function of flow rate for selected liquids.

The instrument system includes a pair of K-type thermocouples for measuring temperature changes on the cold plate surface. Temperatures are monitored on the coolingVIEW interface.

The system features easy setup and operation to save time when evaluating different cold plate models. Designed for accuracy and convenience, it simply requires setting the starting and ending coolant flow rates, and choosing the dwell time, pumping power and other parameters. These are easily done on any PC using the system’s user-friendly application program.

The iFLOW-200 features separate controller and hydraulics enclosures with USB connections. The hydraulic package includes a fluid level indicator, coolant inlets/outlets from/to the cold plate under test, ports for surface temperature thermocouples, and a fluid cooling system for its internal heat exchanger.
