Breif of Cold Plate Technologies

Performance requirements generally dictate choice of cold plate technology and design, and cold plate technology will drive cold plate cost. Generally, the cold plate's cost will increase with improving performance. Cold plate technologies include Press-Lock tubed, gun-drilled with or without expanded tubes, channeled, and brazed with internal fin. These technologies are listed in order of what is typically increasing cold plate efficiency and cost:

·         Press-Lock Tubed Cold Plates - Press-Lock™ tubed cold plates have copper or stainless steel tubes pressed into a channeled aluminum extrusion. Custom tubed cold plates can be designed in virtually any shape or size and the fluid path can be custom designed for optimal thermal performance. Custom coatings, machining, drilling, and tapping may be incorporated as well.

·         Gun-Drilled Cold Plates - Gun-drilled cold plates are fabricated by drilling a hole through an aluminum plate, and, when applicable, inserting and expanding copper or stainless steel tubing. This results in dual-sided cold plates that can be drilled or tapped. One additional benefit of gun-drilled cold plates is that they can have tighter tolerances than tubed cold plates, specifically for flatness requirements.

·         Channeled Cold Plates - Channeled cold plates are extrusions with multi-channels, machined channels, or other methods of forming channels. The extrusions can provide only straight channels, but machining and other new metal cutting methods can provide a much more efficient shape. Channeled cold plates can be manufactured in any length, and assembled in a ladder configuration or integrated into a base plate for large area cooling. They can also be conversion coated or anodized for added protection. Several patterns for different ranges of required impedance, pressure drop, and flow have been developed.

·         Inner-Finned Brazed Cold Plates - Inner-finned brazed cold plates consist of two plates metallurgically bonded together with internal fin. They can be vacuum-brazed with a variety of fin densities and shapes (plain, louvered, lanced-offset, etc.). This internal fin, such as the fin  adds valuable heat transfer surface and adds turbulence to the flow. Brazed cold plates generally have the most flexibility with their design.
