In some examples, there are two support arms 622 for each cold plate 630, with the support arms 630 being located on opposite sides of their corresponding cold plate 630 (see FIGS. 1 and 9). A pair of support arms 622 may be connected to their cold plate 630 via a radial spring 640 (described in greater detail in section 1.2.3 below).
Each of the support arms 622 may have a first end that is connected to an engagement bar 626 (see FIGS. 1 and 10). Thus, all of the support arms 622 are fixed relative to one another by virtue of being connected to the same engagement bar 626.
At least one of the support arms 622 has a second end that is connected to a hinge 623, which enables the support arm 622 to pivot or rotate relative to the system board 2. In some examples, more than one of the support arms 622 may be connected to the hinge 623 (see FIGS. 1 and 10). In some examples, all of the support arms 622 may be connected to the hinge 623. In some examples, less-than-all of the support arms 622 may be connected to the hinge 623. For example, as illustrated in FIG. 10, the two outermost support arms 622 are connected to the hinge 632, while the remaining support arms 622 are shortened and are not connected to the hinge 632. Those support arms 622 that are connected to the hinge 623 constrain motion of the engagement bar 626 relative to the system board 2.
