Abstract

A cold plate has parallel channels that carry cooling water from an inlet at one corner to an outlet at the diagonally opposite corner in flow paths that are generally parallel. The flow path provides improved cooling, and the generally parallel alignment of the walls that define the cooling channels makes the cold plate more flexible in the direction at right angles to these walls so that the cold plate conforms closely to the shape of the circuit module.

Cold Plate from Thermal Conduction Module with Improved Flow Pattern and Flexible Base

A cold plate has parallel channels that carry cooling water from an inlet at one corner to an outlet at the diagonally opposite corner in flow paths that are generally parallel. The flow path provides improved cooling, and the generally parallel alignment of the walls that define the cooling channels makes the cold plate more flexible in the direction at right angles to these walls so that the cold plate conforms closely to the shape of the circuit module.

Some circuit modules are arranged to conduct heat from the circuit to an outer metal surface. This metal portion of the circuit module is cooled by contact with a cold plate. A cold plate is a metal plate that has an inner passage for cooling water. The cold plate is mounted in close contact with the circuit module for heat transfer.

The drawing is a plan view of a section of the cold plate showing the body 2 of the cold plate that forms the outside walls 3 of the cooling channels and the elements that form interior walls 4 that establish parallel cooling channels 5, 6.
