Temperature, circuit coolant (averaged) result

The Temperature, circuit coolant (averaged) result shows the average temperature of the coolant inside the cooling circuit, calculated using the finite element method (FEM).

Using this result

The Cool analysis log contains the change in coolant temperature from coolant-in to coolant-out. If the increase is unacceptable,(greater than 2-3°C), use the Temperature, circuit coolant (averaged) result to determine where the greatest increase in temperature occurs.

In parallel circuits, even though the final increase in coolant temperature from coolant-in to coolant-out is small, the coolant may have reached a high temperature in some sections of the cooling channels.

The following events occur when coolant flows through one channel:

• The temperature of the coolant increases.
• The high temperature coolant mixes with the low temperature coolant.
• The coolant leaves the circuit.

When this occurs, the end temperature is not the maximum coolant temperature; therefore, you should always look at the circuit coolant temperature result in parallel circuits.

Things to look for

When viewing the Temperature, circuit coolant (averaged) result, watch for the following.

• The inlet to outlet temperature rise should be no more than 2-3°C. Higher values may indicate a wider mold surface temperature range, which is of primary importance.
• Hot spots.
