Abstract:
1. A cooling device for an electronic component, the cooling device including: (a) a first heat sink part having a component surface adapted to be placed in a heat transfer relationship with the electronic component; (b) a second heat sink part adapted to be placed together with the first heat sink part in an operating position; (c) one or more first projections making up a contact surface of the first heat sink part, and one or more second projections making up a contact surface of the second heat sink part, wherein the contact surface of the first heat sink part is adapted to mate with the contact surface of the second heat sink part with the one or more first projections interdigited with the one or more second projections when the first heat sink part and the second heat sink part are placed together in the operating position; (d) one or more channels formed in the second heat sink part at least partially through one or more of the second projections for carrying a flow of liquid coolant there through; and (e) a supply connection and a return connection included with the second heat sink part, wherein both the supply connection and the return connection are in fluid communication with the one or more channels.
