Abstract: An arrangement having a cooling function is provided, comprising a circuit board, a plurality of heat generating devices attached to the circuit board, a cooling device thermally connected to one of the plurality of electronic devices, and a coolant plate. An example of the arrangement can include a source of pressurized coolant fluid connected to the coolant plate and adapted to cause the coolant fluid to be transferred between the coolant plate and the cooling device. In addition or alternatively, the arrangement can include a plurality of flexible conduits and an adjustment device adapted to selectively adjust he height of the cooling device. In addition or alternatively, a cooling apparatus within a cooling arrangement can comprise a cooling device, a coolant plate, and a coolant pathway including a first passage formed in the coolant plate and a second passage formed in the cooling device.

Abstract: A tubular stud-nut providing precise, adjustable physical separation between a first and second component. The stud-nut includes male threads on the external cylindrical surface and female threads on the internal surface of the axial bore. The stud-nut also includes a mechanical keying slot to facilitate turning of the stud-nut within a threaded mating hole located within the first component, thus enabling axial adjustment of the stud-nut by extension and retraction. With the stud-nut positioned in the mating hole of the first component, the two components are placed into relative position, Turning the stud-nut with respect to its mating hole, the stud-nut is adjusted to contact the surface of the second component. A locking fastener is threaded into the stud-nut through a concentric aperture in the second component, thereby locking said two components precisely in place. Alternatively, the stud-nut may be used to provide precision adjustment between said components.
