Method and System for Providing a Hybrid Integrally Water Cooled Module

Various types of water cooled cold plates are available such as an aluminum/copper tube and the finned copper cold plates. The aluminum / copper tube cold plate consists of an aluminum plate with embedded copper tubes and slots are provided in the aluminum plate to accept the copper tubes. The copper tubes can be mechanically deformed into the slots. The copper tubes can also be epoxied or soldered in place to provide good thermal contact between aluminum and copper. Liquid, typically water, flows within the copper tubes. The finned copper cold plate is made exclusively out of copper. The internal structure of the finned copper cold plate generally consists of parallel fins separated by flow channels with manifold or plenum regions for distributing liquid flow. Aluminum cold plates are lighter and less costly but are also exhibit lower

thermal performance relative to the finned copper cold plates.

Disclosed is a method and system for providing integrally water cooled module concept that incorporates features and elements of an aluminum/copper tube and a micro-channel cold plate.

An isometric view of a hybrid integrally water cooled module is illustrated in Fig. 1.

The method and system contains a module card assembly that includes three distinct sets of electronic components from power dissipation or a heat load perspective. The three distinct sets are regions of relatively low power dissipation, regions of moderate

power dissipation, and a region of very high power dissipation as illustrated in Fig. 2.

Figure 2

For example, the low power dissipation regions can dissipate 70-90 Watts (W) and moderate power dissipation regions can dissipate 90-120 W. The moderate power dissipation regions possess less surface area than the lower power regions. A very

high power region can dissipate 700-800 W.
