ADDITIVELY MANUFACTURED HEAT TRANSFER DEVICE
FIG7 is a cross sectional view of the cold plate of FIG3, along line 7-7FIG8 is a cutaway isometric view of another illustrative cold plate as described herein
FIG7 is a cross-sectional view of cold plate 100 along line 7-7, through a cross passage 144 and facing toward input wall 124. It should be noted that the rest of the plurality of cross passages 144 match the one depicted. Further, the plurality of cross passages 150 are vertically mirrored relative to the depicted cross passage 144, but otherwise matching the depicted cross passage.

['1. An additively manufactured heat transfer device (10,100, 200, 312), comprising: an enclosure portion (12, 110, 210, 318) including outer walls (18, 108, 208, 324), the outer walls containing a first inner channel (14, 128, 228, 334) configured to direct flow of a coolant fluid, a first fluid intake port (32, 136, 234, 321) connected to the first inner channel, the first fluid intake port configured to direct flow of a coolant fluid through an outer wall (20A, 124, 224, 324) of the enclosure portion into the first inner channel, and a first fluid outtake port (34, 138, 238, 323) connected to the first inner channel, the first fluid outtake port configured to direct flow of a coolant fluid through an outer wall (20B, 126, 218, 324) of the enclosure portion out of the first inner channel, wherein the first inner channel is defined by internal walls (40, 132, 232, 338), the enclosure portion and the internal walls forming a single additively manufactured unit.', '5. The heat transfer device (10, 312) of any of claims 2-4, wherein the enclosure portion (12, 318) has first and second opposing heat transfer sides (26, 326, 328), the first inner channel (14, 334) being closer to the first heat transfer side than the  second heat transfer side, the second inner channel (16, 336) being closer to the second heat transfer side than the first heat transfer side.', '10. A method (600) of manufacturing a heat transfer device (10,100, 200, 312), comprising: printing (602, 604) a first housing (12, 110, 210, 318) having an external heat transfer face (26, 118, 218, 330), and an internal wall structure (40, 132, 232, 338, 342, 350) defining a first inner channel (14, 128, 228, 334) configured to channel fluid for cooling the heat transfer face.']
