I’m working on a project involving a thermoelectric cooler, and options for small aluminum or copper blocks have been few and far between. However, I found many cheap aluminum and copper blocks on Amazon designed for water cooling CPUs. I know that these aren’t solid blocks; they are hollow with fins to disperse heat to a stream of water which would run through it. Would such a block be effective at transferring heat between a heat source and a heatsink on the other side of the block? There will be no water running through it.

Will it work at all? Yes

Will it work as good as a solid chunk of aluminium? No

Expect the performance to be about one-fourth as effective as a solid chunk of aluminium.

Why? Because this thing has channels for water, that don't conduct heat, and that are not oriented favorably for your use.
