Abstract

A cold plate for electronic devices has an improved fin pattern for increased heat transfer. Four fins extend from two opposite walls of the cold plate to form a sinuous path for water flow. Each parallel segment of the path is relatively wide and is further divided into four parallel channels by a three by three parallel line of short fins. The gaps between the short fins increase the turbulence in the water flow. The parallel channels provide increased fin area with low flow resistance. The drawing is a top view of a cold plate before the top is attached.

Cold Plate for Thermal Conduction Module With Reduced Water Flow Resistance, Increased Fin Area, and Improved Water Turbulence

A cold plate for electronic devices has an improved fin pattern for increased heat transfer. Four fins extend from two opposite walls of the cold plate to form a sinuous path for water flow. Each parallel segment of the path is relatively wide and is further divided into four parallel channels by a three by three parallel line of short fins. The gaps between the short fins increase the turbulence in the water flow. The parallel channels provide increased fin area with low flow resistance. The drawing is a top view of a cold plate before the top is attached. It shows the base 2, the side walls 3, a water inlet and outlet 4, fins 5 extending from two of the walls to form a sinuous path for water flow, short fins 7, the gap 8 between the short fins, and holes 9, 10 for screws that hold the cold plate to the hat of a thermal conduction module (TCM). The screw pattern has a conventional location 9 in the center and at the edge and additional locations 10 that improve the contact between the cold plate and the TCM hat.
