  • Patent number: 9826655
    Abstract: A mounting assembly for accurately positioning, attaching, and supporting a circuit board such as a midplane board within a chassis. The assembly's design facilitates an improved assembly method that includes fastening the board to the chassis so to provide reliable connector mate and rapid assembly. The mounting assembly includes a clamp member) and a spring assembly that act in combination to secure a circuit board onto datum features provided on a chassis and/or its modified and/or lightweight alignment bulkhead, which is part of the new assembly. The new assembly design enables a tight tolerance loop between mating components while also providing a more consistent connector engagement when compared with many prior device designs. In some embodiments, a single fastener (e.g., a nut) is used to attach the clamped and captured circuit board to the chassis. The board is “captured” as it is sandwiched between the modified bulkhead and the clamp.

Normal operation of the thermal load can be performed while efforts are made to restore the fluid coolant system.

    Abstract: Cooled electronic assemblies, and a method of decoupling a cooled electronic assembly, are provided. In one embodiment, the assembly includes a coolant-cooled electronic module with one or more electronic components and one or more coolant-carrying channels integrated within the module and configured to facilitate flow of coolant through the module for cooling the electronic component(s). In addition, the assembly includes a coolant manifold structure detachably coupled to the electronic module. The manifold structure, which includes a coolant inlet and outlet in fluid communication with the coolant-carrying channel(s) of the electronic module, facilitates flow of coolant through the coolant-carrying channel, and thus cooling of the electronic component(s). Coolant-absorbent material is positioned at the interface between the electronic module and the manifold structure to facilitate absorbing any excess coolant during a stepwise detaching of the manifold structure from the electronic module.
