  • Heat sink and method of making same
    Patent number: 8757246
    Abstract: A heat sink includes a fluid channel and a cooling wall in contact with coolant flowing in the fluid channel. The channel is configured to vary the velocity of coolant along the length of the fluid channel to vary the coolant's heat transfer coefficient and thereby compensate for the coolant's temperature rise along the length of the fluid channel. The result is a heat sink that is isothermal along its length.
