Abstract

In this improved cold plate, the bolts that attach the cold plate to the hat of a thermal conduction module (TCM) are moved in from the periphery to maintain better contact between the surfaces of the cold plate and the hat. Conventionally, a cold plate is made from interfitting upper and lower metal blocks and has inlet and outlet connections for chilled water and a serpentine water path formed in one or both blocks. At the center of the cold plate the conventional flow pattern is divided by an island that accommodates a central bolt hole. The drawing, a top view of one half of the cold plate, shows a series path 2 for chilled water to flow between a water inlet 3 and outlet 4 and conventional bolt holes 5 at the corners and at the center.

TCM Cold Plate With Chilled Water Flow Pattern to Accommodate Bolts Located Away From the Periphery

In this improved cold plate, the bolts that attach the cold plate to the hat of a thermal conduction module (TCM) are moved in from the periphery to maintain better contact between the surfaces of the cold plate and the hat. Conventionally, a cold plate is made from interfitting upper and lower metal blocks and has inlet and outlet connections for chilled water and a serpentine water path formed in one or both blocks. At the center of the cold plate the conventional flow pattern is divided by an island that accommodates a central bolt hole. The drawing, a top view of one half of the cold plate, shows a series path 2 for chilled water to flow between a water inlet 3 and outlet 4 and conventional bolt holes 5 at the corners and at the center. The center bolt is located in an island 6, and two additional islands 7 are formed to accommodate bolt holes 8. Peninsulas 9 accommodate bolt holes 10.
