Abstract

Some water cooled cold plates have an internal pattern of pins or other fin structures that extend from the floor of the cold plate to increase the surface area in contact with the water. Water flows from an inlet to an outlet through the spaces between the pins and carries off heat from a circuit module that is in contact with the cold plate. Diverters, for example, beads, are located in some of the spaces between the pins to partially block the space and thereby divert the water to areas of the cold plate that do not have the beads. The diverters are smaller than the space between the pins, and they allow water to flow through these spaces at a suitable rate. The diverters can be used with other flow control devices such as baffle plates. The diverters are large enough to be trapped in the space between pins.

Cold Plate for Circuit Module With Partial Flow Diverters Locatable in a Pattern to Establish a Selected Flow Pattern for Cooling Water

Some water cooled cold plates have an internal pattern of pins or other fin structures that extend from the floor of the cold plate to increase the surface area in contact with the water. Water flows from an inlet to an outlet through the spaces between the pins and carries off heat from a circuit module that is in contact with the cold plate. Diverters, for example, beads, are located in some of the spaces between the pins to partially block the space and thereby divert the water to areas of the cold plate that do not have the beads. The diverters are smaller than the space between the pins, and they allow water to flow through these spaces at a suitable rate.

The diverters can be used with other flow control devices such as baffle plates. The diverters are large enough to be trapped in the space between pins. The diverters can have other shapes such as cylindrical. They can be made of metal, glass, ceramic or other durable materials. See [*] for a discussion of general techniques of using beads in a cold plate. The diverters are particularly useful with a cold plate that has the water inlet and outlet connections at locations that produce an undesirable flow pattern. A pattern for a suitable water flow is established and a template is constructed for loading the diverters into the cold plate during manufacture of the cold plate...
