CPC H05K 7/20254 (2013.01) [H05K 7/20781 (2013.01)] | 17 Claims |
1. A cold plate comprising:
a first frame including:
a first frame body having a planar first base surface, an annular first mating surface, and at least one exterior sidewall, wherein the first mating surface is spaced apart from the planar base surface and surrounds a first recess in the first frame body, the first recess having a bottom and at least one interior sidewall,
a plurality of first heat transfer fins positioned in the first recess, each first heat transfer fin having a first edge thermally coupled to the bottom and a second edge positioned substantially at a plane defined by the first annular mating surface,
a first fluid channel positioned at the bottom of the first recess, and
a first fluid port positioned in the at least one frame sidewall, the fluid port being fluidly coupled to the first fluid channel;
a second frame including:
a second frame body having a planar second base surface, an annular second mating surface, and at least one exterior sidewall, wherein the second mating surface is spaced apart from the second base surface and surrounds a second recess in the second frame body, the second recess having a bottom and at least one interior sidewall,
a plurality of second heat transfer fins positioned in the second recess, each second heat transfer fin having a first edge thermally coupled to the bottom of the second recess and a second edge positioned substantially at a plane defined by the second annular mating surface, wherein each second heat transfer fin has a corresponding first heat transfer fin and wherein each second heat transfer fin is separate from the corresponding first heat transfer fin,
a second fluid channel positioned at the bottom of the second recess, and
a second fluid port positioned in the at least one frame sidewall, the fluid port being fluidly coupled to the second fluid channel;
wherein the second mating surface is positioned in sealing contact with the first mating surface so that the first recess and the second recess form a fluid chamber and wherein the second edge of each first heat transfer fin is in contact with the second edge of a corresponding second heat transfer fin, so that the plurality of first heat transfer fins and the plurality of second heat transfer fins form a plurality of fin channels in the fluid chamber.
