Compact liquid cooled heat sink
First Claim
1. A heat sink apparatus for use with a liquid refrigerant that tends to generate gas during the cooling process wherein at least some of the gas tends to accumulate on the internal surfaces of heat sink liquid channels forming gaseous pockets that in turn cause surface hot spots, the apparatus for minimizing the surface host spots and comprising:
- a first sink member having first and second substantially oppositely facing surfaces, the second surface for receiving at least one heat generating component;
a second sink member having at least a first surface, the first surface of the second sink member secured to the first surface of the first sink member, the first surface of one of the sink members forming a cavity extending between first and second cavity ends and including a cavity surface, the first side of the other of the sink members including a cover surface that substantially covers the cavity and substantially oppositely faces the cavity surface so as to form a channel;
at least one of the cavity surface and the cover surface forming a plurality of protuberances between the first and second cavity ends that extend into the cavity, the protuberances increasing turbidity of the liquid flowing therethrough such that channel surface air pockets are substantially eliminated;
at least one of the first and second sink members forming an inlet at the first end of the channel; and
at least one of the first and second sink members forming an outlet at the second end of the channel.
