Abstract

This article concerns a tool removal system used to separate the cold plate from the TCM module. The interface surfaces of the TCM/cold plate is machined to a precise flatness specification. This flatness is required to improve the heat transfer properties. A layer of oil is introduced between the surfaces, to further enhance heat transfer properties. When these two surfaces are combined with oil in between, then a capillary action occurs, requiring a great amount of force to separate the two surfaces. This separation has to be done without causing damage or distortion to the parts. Fig. 1 shows how the tool is inserted into the cold plate body. The tool swings open at pivot points 2, and fastened into the cold plate by tightening cams 2. The cold plate is lifted from the TCM by the action of levers 3. Fig.

Cold Plate Hat with Oil Interface Tool Remover

       This article concerns a tool removal system used to
separate the cold plate from the TCM module.  The interface surfaces
of the TCM/cold plate is machined to a precise flatness
specification.  This flatness is required to improve the heat
transfer properties.  A layer of oil is introduced between the
surfaces, to further enhance heat transfer properties.  When these
two surfaces are combined with oil in between, then a capillary
action occurs, requiring a great amount of force to separate the two
surfaces.  This separation has to be done without causing damage or
distortion to the parts.  Fig. 1 shows how the tool is inserted into
the cold plate body.  The tool swings open at pivot points 2, and
fastened into the cold plate by tightening cams 2.  The cold plate is
lifted from the TCM by the action of levers 3.  Fig. 2 displays the
top view of the tool inserted into the cold plate.  Fig. 3 is a cross
section of the tool, cold plate and TCM.
