A board retainer assembly including a cold plate with plain generally rectangular grooves for receiving the edge of a board and a board retainer. The retainer being separate from the cold wall and adapted to expand and releasably clamp the edge of a board in the groove against a thermal wall of the groove. The retainer including an elongated body adapted to be received in the groove with an elongated face engaged with the edge of the board. A resilient spring element is adapted to engage the opposite wall of the groove under the urging of a camming rod. The camming rod rotates in the space between the resilient spring element and a camming surface on the body of the retainer. The camming rod is generally oval shaped with a major and a minor axis. Rotation of the camming rod one quarter turn causes the width of the retainer to expand by an amount equal to the difference between the lengths of the major and minor axes. The camming surface has a profile such that a quarter turn of the camming rod which serves to bring expand the width of the retainer also causes the longitudinal axis of the camming rod to shift outward towards the resilient spring element.
