Cooling Efficiency

This result shows the cooling efficiency of each cooling channel. It shows the percentage of heat withdrawn by the cooling channel.

If Qi is the total heat flows into the i-th cooling channel surface.

When Qi is positive, it means that the total heat is absorbed from its surface and the cooling efficiency is defined as the following equation

Cooling efficiency =clip0038

where Qa is the total absorbed heat through cooling channel surface., and Qma is the total absorbed heat through mold surface via surroundings.

When Qi is negative, it means that the total heat is released from its surface and the cooling efficiency is defined as the following equation

Cooling efficiency =clip0039

where Qr is the total released  heat through cooling channel surface and Qmr is the total released  heat through mold surface via surroundings

Positive value represents cooling efficiency, whereas negative value represents heating efficiency.
