Simulating plastic flow through a nozzle

The polymer flow is non isothermal, and I used the non-newton-carreau model to describe dynamic viscosity.
I had to use 'heat transfer in solids' in order to observe heat flow from the polymer in to the aluminium nozzle.
Using convective cooling, I am able to observe a cooling temperature gradient around the cooling channel. However, this cooling gradient is supposed to extend out in to the molten polymer as well (as this is the whole purpose of having a cooling system!!), but I haven't been able to observe any perceptible difference with or without the cooling channel active.
Am I doing something wrong?
