Rotatable cold plate assembly for cooling pluggable modules

The radial spring 640 allows the cold plate 630 to translate a limited distance in two dimensions relative to the pivoting support 621. More specifically, the radial spring 640 allows the socket 641 (to which the cold plate 630 is connected) to translate relative to the engagement portions 643, a limited distance in any direction within the X-Y plane shown in
The radial spring 640 also may allow the cold plate 630 to rotate relative to the support arms 622 through a limited angle around an axis of the axial support 636. More specifically, the radial spring 640 allows the socket 641 (to which the cold plate 630 is connected) to rotate relative to the engagement portions 643 through a limited angle around a central axis of the spring 640.
The movement (translation or rotation) of the socket 641 relative to the engagement portions 643 results in the spring arms 642 elastically deforming, which generates a restoring spring force that resists the movement but allows it to occur. Thus, the socket 641 is biased towards its original location in the center of the spring 640 and its original orientation.
The fact that the radial spring 640 allows such movement and generates the opposing spring force as a result may help to ensure good thermal contact between the cold plate 630 and the pluggable module 700.
