DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is depicted by way of illustration specific examples in which the present disclosure may be practiced. It is to be understood that other examples may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure.
Electronic system designs must balance conflicts between power density, spatial layout, temperature requirements, acoustic noise, and other factors. Liquid cooling can be more efficient than air cooling. As the liquid goes through the plumbing connections the risk of leakage of liquid within the electronic device is introduced.
In examples, an apparatus to cool an electronic module is provided. The apparatus includes a support member and a retaining member. The support member to receive the cooling module. The support member includes a cooling module alignment member to align the cooling module therein. The retaining member to secure the cooling module therein.

The support member 120 to receive the cooling module. The support member 120 includes a cooling module alignment member to align the cooling module with a cooling module connector at a front portion of the cooling module. The cooling module cools the electronic module by removing heat from the electronic module. A single cooling module may cool at least one electronic module and depending on the configuration may cool a plurality of electronic modules. The retaining member 140 to secure the cooling module therein.
FIGS. 2-3 illustrate examples of the apparatus 100 of FIG. 1 with a wet disconnect cooling module according to examples. A wet disconnect cooling module is a module assembly with cooling components that cool an electronic module using a liquid cooling method that transfers fluid between the cooling module and the electronic module using wet or liquid connections that transfer a fluid therethrough. The liquid cooling occurs within the electronic module using the fluid that is transferred to the electronic module to remove heat from electronic components. The heat from the electronic components in the electronic module is transferred to the fluid to cool the electronic components. The fluid, after receiving the heat from the electronic components, is removed from the electronic module with the heat. The fluid may be returned to the cooling module for removal of the heat via a recycling method, or transfer of heat from the cooling module to an external system that may recycle the fluid. For example, the external system may include an outdoor air cooled heat exchanger or a building chilled water loop.
Referring to FIG. 2, a perspective diagram of the apparatus 100 is illustrated. The apparatus 100 includes a support member 120 and a retaining member 140. The support member 120 receives the cooling module 230 along an alignment member 226.

The retaining member 140 may further include support apertures, such as a pair of apertures formed in the retaining wall 342 that are formed to receive and/or engage with support pins extending from the cooling module, as illustrated in FIG. 6.
The cooling module 230 is illustrated in a position aligned for insertion into the support member 120 with the cooling module connectors 238 that mate with the electronic modules visible; however, no electronic modules are illustrated in the rack or support member 120 of FIG. 3. For example, the wet disconnect water wall includes a fluid manifold 236 to distribute a fluid to and from the electronic module and a cooling module connector 238 that connects to the electronic module to provide and remove heat therefrom using the fluid.
The apparatus 100 is designed to interchangeably receive a plurality of cooling modules 230. The design of the support member 120 and the retaining member 140 accommodate the plurality of cooling modules 230. The cooling module 230 may include, for example, a dry disconnect water wall, a wet disconnect water wall, and/or a mechanical support wall for use with air cooling. For example, when the cooling module 230 is a dry disconnect water wall, the cooling module 230 includes a fluid manifold 236 to direct a cooling fluid and a thermal mating member (not shown) on an opposite side to receive heat from the electronic modules. The thermal mating member may be positioned adjacent to a heat block that is along the edge of the electronic module that aligns with the cooling module 230.

The electronic module 530 includes computer solutions, storage solutions, network solutions, and/or equipment optimized to deliver cloud services. The electronic module 530 may be supported by the support member 120, such as a server rack illustrated in FIG. 5. The electronic module 530 mates with the cooling module 230 using an electronic module connector 538. The electronic module connector 538 connects to the cooling module connector 238. The electronic module connector 538 includes an electronic supply connector 537 and an electronic module return connector 539.

The electronic module return connector 539 connects to the cooling module return connector 239 to remove the fluid from the electronic module 530 and provide the fluid to the cooling module 230 via the electronic module return tube 534.
The cooling module supply connector 237 and the cooling module return connector 239 are positioned at a front portion 231 of the cooling module 230 i.e., an end opposite the fluid supply and return lines 222, 224. Positioning the cooling and electronic connectors 238, 538 at the front portion 231 of the cooling module 230 and the rack increases the visibility of the connectors and potential leaks. The connection at the front portion 231 may also allow visual confirmation of proper connection between the cooling module 230 and the electronic module 530 since the connection is at the front portion 231 of the cooling module 230 and the front of the electronic module 530.
The electronic module 530 includes an electronic module supply tube 532 and an electronic module return tube 534. The electronic module supply tube 532 connects to the electronic module supply connector 537 and a heat sink 540 in the electronic module 530 to supply fluid to the heat sink 540. The electronic return tube 534 connects to the electronic module return connector 539 and the heat sink 540 to receive fluid from the heat sink 540. The electronic module 530 may also include additional electronic components 535, such as a processor, memory, a hard drive, and/or a fan. For example, direct liquid cooling may be supplemented with other cooling methods, such as air cooling, which may be more cost effective than providing coolant plumbing lines to all heat sources.
The electronic module 530 may further include an engagement member 460 to position the electronic module 530. For example, the engagement member 460 positions the electronic module 530 by engaging with the electronic module 530 and aligning the electronic module 530 with the cooling module 230 to allow engagement therewith. An example of the engagement member 460 includes a lever that locks the electronic module 530 into place. For example, the lever 660 extends from the support member 120 via the portion 662 and engages with a fixed pin 664 on the coolant module 230 and an engagement pin 666 on the electronic module 530. The engagement member 460, such as a lever may also be used to ensure proper alignment of the electronic module 530.
A heat exchanger 350 may be positioned adjacent to the cooling module 230. The heat exchanger 350 removes heat from the air that is being recirculated within the enclosure by fans. This cooled air keeps the smaller electronic components on each electronic module 530 cool, since the smaller electronic components may not be connected to the liquid cooling system. The fluid with the heat from the electronic module 530 and the heat exchanger 350 may then be recycled by being pumped to an outdoor air cooled heat exchanger, such as a radiator, or cooled using a building chilled water loop.
In an alternate example, the heat exchanger 350 may recycle the fluid received from the fluid return line 224. The fluid from the fluid return line 224 may be a higher temperature due to receiving heat from the electronic module 530. The heat exchanger 350 may remove the heat and return the fluid to the fluid supply line 222 at a lower temperature to allow reuse of the fluid and continuous cooling of the electronic module 530.
The support member 120 also includes a power and signal backplane 510 in the back end 220 or rear. The power and signal backplane 510 supplies power and facilitates communication between the plurality of electronic modules 530.

For example, the engagement member 460 may include a lever that engages with the electronic module 530 in a secured position to prevent movement. Similar to the retaining member 140, the engagement member 460 is used to maintain the fluid-tight connection between the electronic module and the cooling module 230 and prevent a leak.
The system 400 may connect the cooling module 230 and the electronic module 530 using any combination of attachment members and/or alignment members. For example, the combination of the retaining member 140, the engagement member 460, an electronic module alignment member 338, and/or the cooling module alignment members 226 are used to align and engage the cooling module 230 and the electronic module 530.
The system 400 is designed to interchangeably receive a plurality of cooling modules 230. The design of the support member 120 and the retaining member 140 accommodate the plurality of cooling modules 230. The cooling module 230 may include for example, a dry disconnect water wall, a wet disconnect water wall, and/or a mechanical support wall for use with air cooling. For example, when the cooling module 230 is a dry disconnect water wall, the cooling module 230 includes a fluid manifold 236 to direct a cooling fluid and a thermal mating member (not shown) on an opposite side to receive heat from the electronic modules 530. The thermal mating member may be positioned adjacent to a heat block that is along the edge of the electronic module that aligns with the cooling module 230.
FIG. 7 illustrates a flow chart 700 of a method to cool an electronic module according to an example. The method to insert a cooling module into a support member in a position to align the cooling module with an electronic module in block 720. For example, a cooling module alignment member may be used to align the cooling module. The cooling module removes heat from the electronic module.
In block 740, the cooling module to mate with the electronic module. The mating of the cooling module and the electronic module forms a fluid-tight connection therebetween that enables the transfer of fluid therebetween. The fluid is utilized to remove heat from the electronic module. The fluid-tight connection occurs in a portion of the cooling module opposite a backplane. For example, the cooling module receives fluid via a fluid supply line connection and a fluid return line connection near the backplane. The cooling module includes a cooling module supply connector and a cooling module return connector. The electronic module includes an electronic module supply connector and an electronic module return connector. The cooling module supply connector and the electronic module supply connector mate with one another to form a fluid-tight seal therebetween and enable fluid to transfer therethrough. Similarly, the cooling module return connector and the electronic module return connector mate with one another to form a fluid-tight seal therebetween and enable fluid to transfer therethrough.
The method to secure the cooling module using a retaining member connected to the support member in block 760. The alignment and/or securement of the cooling module may also be aided using an alignment member, such as a groove in the base of the support member, to position the cooling module. The method to engage the electronic module with the support member using an engagement member extending from the support member in block 780. The engagement of the electronic module may also be aided through use of an electronic module alignment member, such as a rail, guiderail, and/or alignment pins to receive, hold, and/or position the electronic module to connect with the electronic module supply connector with the cooling module supply connector and the electronic module return connector with the cooling module return connector.
