DETAILED DESCRIPTION

[0058] There are now described various novel data processor cartridges, in which two data processor assemblies are provided in a novel packaging arrangement. The data cartridges described may be suitable for incorporation into a host assembly, which comprises a receiving structure arranged to carry multiple cartridges. Like reference numerals are used for similar or identical features.

[0059] In the embodiments which are now described, a cartridge comprises two connectors which are each configured to receive a respective data processor assembly. Such data processor assemblies may comprise a GPU PCIe card.

[0060] Common to all of the embodiments which are now described, is the feature of the connectors being mounted in an inverted orientation to one another. The simplified (for reasons of clarity) FIGS. 1, 1b, 1c, 2a, 2b and 2c which are now referred to, further explain this aspect.

[0061] With reference to FIGS. 1a, 1b and 1c, there are shown schematic views of a GPU PCIe cards 10 and 11, and a portion 1 of a cartridge housing. The portion 1 of the cartridge housing is provided with two PCIe slots 2A and 2B, which are arranged to receive a respective connector portion 10a and 11a of each card 10. It will be appreciated that for ease of representation, the GPU module is not shown.

[0062] Structural components 3 may be metal or plastic brackets providing stability and rigidity to the cartridge assembly.

[0063] The slots 2A and 2B are mounted to the portion 1. The slots are arranged in parallel spaced-apart fashion, albeit said slots are offset from one another. The slots face into an internal space of the cartridge in which the cards 10 and 11 reside when connected to the slots, Additionally, the slot 2A is arranged at an inverse orientation to the slot 2B (it being noted that a connector of a card is arranged to be received in a slot in only one orientation).

[0064] Reference is now made to FIGS. 2a, 2b and 2c, which show that each of the cards 10 and 11, have been inserted into its respective slot. Communication to and from the cards 10 and 11 is achieved by a flex-circuit or PCIe cable 6,

[0065] FIGS. 3a and 3b show a PCIe card on which a GPU module 15 is provided (on one side thereof).

[0066] Taking account of the above, there will now be described three embodiments in which the orientations of the slots 10 and 11 are such that the respective CPU modules face inwardly, that is towards on another. The side of each card on which the GPU module is located can be termed the hot side, and the opposite side. the cool side.

[0067] Turning to FIG. 4, there is shown a hot-hot configuration in which a heat exchanger is located intermediate of the two cards 10 and 11. The innermost facing surfaces of the GPU modules of the cards are brought into contact (or at least sufficient thermal contact) with the heat exchanger. The heat exchanger comprises two outer heat spreader layers 20, which are bonded to a heat conductive core 21.

[0068] FIG. 5 shows a further embodiment which uses the hot-to-hot concept in which a heat sink 30 is located intermediate of the cards 10 and 11. The heat sink 30 is a container which includes a liquid which receives heat from the GPUs and carries away.

[0069] FIG. 6 shows yet a further hot-to-hot implementation in which the heat sink 30 is filled with oil and two piezo electric pumps 40 cause the fluid to carry excess heat away.

[0070] FIG. 7 shows a final example of a hot-to-hot implementation in which the heat sink comprises a water reservoir connected to an inlet conduit 30a and an outlet conduit 30b. An external pump (not shown) pumps water through the reservoir so as to carry heat away.

[0071] FIGS. 8 and 9 show two examples of cold-to-cold configurations, in which the GPUs are outwardly facing.

[0072] In FIG. 8a respective heat spreader 55 is held in thermal communication with each GPU. Each heat spreader is made of a highly heat conductive material. The heater spreaders are also in thermal communication with a heat exchanger 50. Air is blown towards the heat exchanger, which carries heat received form the heat spreaders. The embodiment shown in FIG. 8 may be described as air-cooled.

[0073] FIG. 9 shows an arrangement in which two oil filled heat sinks 60 are held in thermal communication with the GPUs.

[0074] FIG. 10 shows a four card arrangement, in which is provided two pairs of inverted PCIe slots, which can be seen as a combination of two of the embodiments shown in FIG. 8, arranged in close proximity.

[0075] FIG. 11 shows a further four card arrangement which comprises a shared direct liquid cooling arrangement. In this, a respective heat exchanger container/vessel 80 is provided for each inverted pair of cards. Each exchanger is provided with an inlet and an outlet. Each inlet is connected to a cold liquid supply and each outlet allows heated liquid to exit the container. The inlet and outlet branches are referenced by 71a, 72a, and 71b, 72b, respectively. Each of the hot branches is connected to a common outlet 72, and a common inlet 71 feeds cold liquid to the two cold inlet branches.

[0076] In the above embodiments, the user of a riser (card) is disclosed which supports the inverted Me slots. As is known, risers are connectable into a motherboard via an edge connector. in alternative embodiments, the concept of inverted PCIe slots remains, but the slots are directly attached to the motherboard, or incorporate a riser into a motherboard, where the space allows. Reference is made to FIGS. 12 and 13 show an example of this, both with the cards inserted into the slots, and showing the slots themselves. As can be seen, two of the slots are arranged in an inverted configuration.
