    a heat sink = un dissipateur thermique

    See the Wikipedia article:
    "component used to cool devices that generate high temperatures"

    This is not the same as a heat sink in, for example, a computer or an LED light bulb. Un réservoir de chaleur is a large, usually natural body that can absorb infinite amounts of heat without changing temperature itself, i.e., an ocean or a river or a large lake, but certainly not a glacier.

    In electronics, it is indeed a "dissipateur thermique". It is also usually called "radiateur" as it radiates the heat and thus cool down the circuit attached to it.

    Just to add a little nuance: I have a text in front of me that says "dissipateur d'énergie thermique comportant un radiateur". So it might be best to stick with "radiator" for "radiateur".
