Metal Hydride storage simulation

I am performing simulation of metal hydride based storage system in Comsol 4.3a. It's a 3D model, I want to implemented variable wall temperature condition to the embedded cooling tubes(ECTs).
But somehow I am not able to do so.
I am using the following physics modules,
1. Heat transfer in porous media(T).
2. Darcy's law.
3. Heat transfer in fluids(T2).
Now for the ECTs I am using inlet face temp as To=293K, outlet face is insulated, and tube wall surtface temp is changing according to the variation To+((T2-To)*(1-exp(-(U*A)/(mf*cpf)))).
But the fluid temperature is not at all changed and remains constant at 298K.
Please help me with this.
Thanks
