For where there isn't any solder, you could put on some of that thermal compound,,the type they use on cpu's (sparingly of course) But just by being in contact with the aluminum, heat will migrate from the Al to the Cu pipe.

I thought that maybe they finally invented some new solder.

I was going to use thermal paste to "connect" my pipe to the aluminum but then I did some math and I do not believe it is needed or will make more then 1-5 degrees difference. But to attach the LED's to the aluminum you bet I will be using thermal compound.
