What is this???

[Super]

Hi, my friend gave me this heatsink, and I don't know anything about it, it has no name on it, just a piece of metal...

can anyone please tell me the name of it, and if it is useful in some way.

Thanks.

can we get some different angles, it almost looks like a thermoengine, but not.
