DETAILED DESCRIPTION

(10) Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings and disclosed herein. Wherever convenient, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

(11) The disclosed embodiments are directed to a bracket and to a stacked structure for supporting brackets in cluster applications.

(12) In a cluster, multiple processors operate in parallel to achieve increased processing power. A mounting system must be employed such that processors in the cluster are physically secured to ensure mechanical stability of a system but in such a way to allow access to the processors and their interfaces to facilitate maintenance of the system. Moreover, the mounting system must dissipate heat that is generated from the processors during their operation thereof while providing minimal interference to the system as a whole.

(13) The following description provides examples of systems for securing a processor to a bracket and an apparatus for mounting a processor for cluster computing. The arrangement of components shown in the Figures is not intended to limit the disclosed embodiments, as the components used in the disclosed bracket may vary.

(14) FIG. 1 shows a bracket 100. Bracket 100 may be formed of a layered acrylic material, for example, by a rapid prototyping process. The rapid prototyping method of manufacturing may include one or more of additive manufacturing processes, solid freeform fabrication processes, and computer numerically controlled (CNC) processes. A number of different additive manufacturing processes have been developed that can be used in accordance with various implementations of this disclosure to rapidly produce a prototype or model of the desired bracket from a three-dimensional (3D) data file defining the structure of the bracket.

(15) In accordance with the disclosed embodiment, bracket 100 may include a base portion 105 and an upright portion 110. Upright portion 110 may extend perpendicularly from base portion 105 and may include a first arm 120 and a second arm 130. Upright portion 110 may be supported relative to the base portion 105, in part by a first gusset member 122 and a second gusset member 132. First and second gusset members 122 and 133 may be substantially triangular in shape and may provide reinforced support at the section of bracket 100 where upright portion 110 intersects base portion 105. In particular, first and second gusset members 122 and 132 may extend substantially perpendicularly to the upright portion 110, and may extend along a portion of the length of upright portion 110. First and second gusset members 122 and 132 are configured to improve the stiffness and load-bearing strength of bracket 100 by reinforcing the intersection of upright portion 110 and base portion 105, preventing high stress concentrations caused by bending moments that would otherwise develop at the intersection.

(16) Bracket 100 may also include a rib 160 where upright portion 110 intersects base portion 105. Rib 160 may extend along the length of base portion 105 of bracket 100 and may be configured to extend substantially perpendicularly to upright portion 110. Rib 160 may add strength and stability to minimize deflection of bracket 100. Increasing strength and stability of bracket 100 may further improve the mechanical reliability of a processor mounted to bracket 100.
