    I see 5 FETs (Field Effect Transistor) attached to a heat sink.
    What I don't see is the part number.

    Make your own?

    Plenty of L section aluminium available, here for example.

    paulktreg has a good point. This is not a purchased heatsink but something the manufacturer made from a standard aluminum extrusion.

    There is no reason it must look like your picture, you may want a different (simpler) shape to move heat from one place to another.

    That probably is a chunk of aluminum angle cut to length and drilled. Lowes, Home Depot, etc. It is an extrusion, not a bent piece. It might be a custom extrusion, but it is not a catalog standard heatsink part. Note the two solderable legs crimped on. This used to be a sign that the part was from a heatsink company, but I've seen CMS shops bring this technique in-house.
