Heat flux, Channel (3D) (averaged) result

The Heat flux, Channel (3D) (averaged) result displays the heat flux of the conformal cooling channel, averaged over the injection cycle.

Values obtained are related to several factors.

  • Mold metal temperature
  • Coolant temperature
  • Coolant flow rate
  • Coolant properties
  • Circuit geometry

In most cases, the conformal cooling channels are cooling the mold and the plot values are positive.

In cases where the conformal cooling channels are heating the mold, a negative flux value results.

Using this result

For localized mold surface temperatures that are either hotter or colder than required, the impact of adjusting the coolant temperature or flow rate can be assessed.

If adjusting these values does not rectify the problem, either modify the existing cooling circuits or add new ones.

The amount of flux removed by a circuit can also be changed by altering the circuit geometry.

Note: Adjustments to the conformal cooling channel must be made in the external CAD package. The new conformal cooling body will need to be imported and treated as a new conformal cooling analysis.

Things to look for

Channels with low Heat flux, Channel (3D) (averaged) values may be redundant. This is often the case with parallel circuits where one branch of the circuit has little coolant flow.

Verify that channels with areas of high heat flux have inlet and outlet coolant temperatures within 5ºC of each other.
