Abstract

For a number of applications, electronic components are cooled by water cooled coldplates which are maintained in separate hardware that are fastened to the electronics to be cooled. For service, the cooling hardware is unfastened and the electronics are removed from the machine. For high performance applications requiring improved cooling, the thermal contact resistance existing at the interface between the cooling and electronic hardware cannot be afforded; thus, the two parts may be integrated together into a single assembly. Disclosed herein is a means to service these high performance electronic components which have their coolant (e.g., water) plumbed directly into the component module hardware. Referring to Fig.

Coolant Switch Box for Integral Cooling System Operation

       For a number of applications, electronic components are
cooled by water cooled coldplates which are maintained in separate
hardware that are fastened to the electronics to be cooled.  For
service, the cooling hardware is unfastened and the electronics are
removed from the machine.  For high performance applications
requiring improved cooling, the thermal contact resistance existing
at the interface between the cooling and electronic hardware cannot
be afforded; thus, the two parts may be integrated together into a
single assembly.  Disclosed herein is a means to service these high
performance electronic components which have their coolant (e.g.,
water) plumbed directly into the component module hardware.
Referring to Fig. 1, a coolant switch box (CSB) 1 is provided to
drain the coolant from module hoses 2 prior to disconnecting the
hoses from module 8, thus preventing system coolant from affecting
electronic equipment.  The CSB also provides an efficient means of
distributing coolant when the coolant distribution unit (CDU), which
contains the pumps and heat exchangers, is located far from the
electronic equipment.  Alternatively, the CSB can be situated under
the raised floor close to the frame of equipment it services or in
the bottom of the frame if sufficient room exists.  The design of the
box, if located in the frame, may be different from the box shown in
the figure but its function will be th...
