Abstract

A cold plate is mounted in its conventional position on the hat of a TCM and is sandwiched between the hat and a mounting plate. The mounting plate has holes at two diagonally opposite corners for the conventional chilled water inlet and outlet piping at the top of the cold plate. The cold plate and the mounting plate have holes at their corners and along each side, and the hat has matching threaded holes that permit the sandwich to be held together by bolts. The conventional center bolt is not used. The mounting plate carries pistons that transmit the force of the bolts to the central portion of the cold plate and thereby maintain good thermal contact between the cold plate and the hat. A piston has a shaft that fits into a hole in the mounting plate and a head that bears against the cold plate.

Thermal Conduction Module (Tcm) With Mounting Plate Carrying Pistons for Applying Force to Cold Plate for Wide Thermal Contact With TCM Hat

A cold plate is mounted in its conventional position on the hat of a TCM and is sandwiched between the hat and a mounting plate. The mounting plate has holes at two diagonally opposite corners for the conventional chilled water inlet and outlet piping at the top of the cold plate. The cold plate and the mounting plate have holes at their corners and along each side, and the hat has matching threaded holes that permit the sandwich to be held together by bolts. The conventional center bolt is not used. The mounting plate carries pistons that transmit the force of the bolts to the central portion of the cold plate and thereby maintain good thermal contact between the cold plate and the hat. A piston has a shaft that fits into a hole in the mounting plate and a head that bears against the cold plate. A conical spring washer is located between the head of the piston and the bottom surface of the mounting plate. The shaft of the piston has an annular groove and the inner surface of a hole in the mounting plate has a matching groove that cooperates with a snap ring to lock the piston to the mounting plate. The groove in the piston extends far enough axially for the axial movement of the piston as the spring is compressed. The pistons can be located in any suitable pattern. For example, two pistons are located in the corners not occu...
