Claim 0:
1. A heat transfer device, comprising:
an enclosure portion including outer walls containing a first inner channel configured to direct a first flow of a coolant fluid and a second inner channel configured to direct a second flow of a coolant fluid, the outer walls including a first conductive wall and a second conductive wall, wherein the first conductive wall and the second conductive wall are parallel and opposing,
a first fluid intake port and a first fluid outtake port connected to the first inner channel,
a second fluid intake port and a second fluid outtake port connected to the second inner channel,
wherein each of the first inner channel and the second inner channel is defined by internal walls, the enclosure portion and the internal walls forming a single additively manufactured unit,
wherein the first inner channel and the second inner channel are isolated from each other, each of the first inner channel and the second inner channel contacting both the first conductive wall and the second conductive wall, and
wherein a first coolant fluid is supplied to the first inner channel by a first fluid system and a second coolant fluid is supplied to the second inner channel by a second, separate fluid system, and the second inner channel and second fluid system are configured to provide fail-safe redundancy for the first inner channel and the first fluid system.
