Abstract

A suspended integrated manifold system providing a means to distribute a liquid coolant to a densely packed array of electronic module and allow access for servicing is disclosed. The assembly is comprised of primary supply and return manifolds that distribute water to movable auxiliary supply and return manifolds facing and connected by flexible hoses to rows of cold plates on modules. The ends of the auxiliary manifolds are mechanically attached to slots in support rails on either side so that they can slide up or down to provide clear access to a row of cold plates and modules requiring servicing.

Suspended Integrated Manifold System With Serviceability for Large Planar Arrays of Electronic Modules

A suspended integrated manifold system providing a means to distribute a liquid coolant to a densely packed array of electronic module and allow access for servicing is disclosed. The assembly is comprised of primary supply and return manifolds that distribute water to movable auxiliary supply and return manifolds that face and are connected by flexible hoses to rows of cold plates on modules. The ends of the auxiliary manifolds are mechanically attached to slots in support rails on either side so that they can slide up or down to provide clear access to a row of cold plates and modules requiring servicing. Top, front and side views of the suspended manifold system connected to cold plates on an array of modules is shown in figure 1. The primary return and supply manifolds are fixed in position and are used to supply water to and from the auxiliary manifolds facing the cold plates and modules on a printed circuit board. The auxiliary supply and return manifolds are incorporated into a single structure with an internal passage on top to serve as the supply manifold and a separate internal passage on the bottom to serve as the return manifold. A hose is connected at one end to the primary supply manifold and a second hose is connected at the other end to the primary return manifold. The auxiliary manifolds are attached to slotted vertical support rails on either side of the board. The means of mechanical attachment (not shown) passes through a slot in each support rail. The hoses connecting the auxiliary manifolds and the input/output ports on the module cold plate are of extra length so as to drape down as shown in the side view in figure 1. The connections between the pr...
