ADDITIVELY MANUFACTURED HEAT TRANSFER DEVICE
FIG12 is a cutaway isometric view of the cold plate quadrant of FIG11
Outer walls 324 contain a first layer 334 and a second layer 336, divided by an internal wall 338. As shown in FIG12, a cutaway view of the quadrant, each layer is divided into plurality of channels 340 by ribs 342. Each layer is configured to direct multiple flows of coolant fluid parallel to external heat transfer surface 330 of back wall 328. In some examples, channels 340 may branch or interconnect, outer walls 324 may include a third layer, and/or quadrant 318 may include any appropriate number and configuration of layers and channels. As shown in FIG12, each channel 340 follows a curved, bent, or cornered path from an input 344 to an output 346. In the present example, the input and output are open ends of cold plate quadrant 318, configured for connection to a bridging component. When assembled to form the front cold plate, input 344 of one quadrant is connected to an output 346 of another quadrant such that together the four quadrants operate in series with a single effective input and output. Each bridging component may include a perpendicular channel connected to the input or output such that channels 340 function similarly to the cross passages described in cold plate 100. Any effective structures or fluid connections may be used to assemble quadrant 318 into front cold plate 312. The front cold plate may be configured for any effective coolant fluid flow pattern.

['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.', '9. The heat transfer device (312) of any of claims 1-8, wherein the enclosure portion (318) has first and second opposing planar sides (326, 328) parallel to a direction of fluid flow through the first inner channel (334), and a first passage (320) from the first planar side to the second planar side configured to guide microwave transmission through the heat transfer device, wherein the first passage has an internal wall structure (350) separating the first passage from the first inner channel.']
