Thermocouple controlled cooling circuit pressure result

The Circuit pressure result for thermocouple controlled cooling is generated from a Cool analysis to show the distribution of pressure along a cooling circuit, averaged over the cycle. It is a time dependant result.

Using this result

The pressure inside the cooling circuits should remain evenly distributed from the inlet circuit pressure to the outlet circuit pressure. Large pressure drops in the cooling circuits are caused by cooling problems, such as the bubbler or the baffle dimensions being too small.

This result can be checked to determine the flow direction in parallel cooling circuits. The pressure is highest at the coolant inlet and lowest at the coolant outlet.

The information obtained from this result is also available in the analysis log.

Note: This result does not take into account the pressure loss due to external cooling lines, fittings, and so forth.

Timing of this result should correspond to the parameters set on the Valve on and Valve off tabs in the Thermocouple controlled cooling inlet dialog. This result should correspond at the exact times that the valve changes status.

Things to look for

When viewing the circuit pressure result, check the following:

• The coolant pressure in each circuit is less than the coolant pump capacity.
• Large pressure drops (inlet−outlet pressure).
