The following cold plate graph, from <a href=\"http:\/\/www.lytron.com\/cold-plates\/cold-plates-overview.aspx\">Lytron<\/a>, compares the normalized thermal resistances of different cold plate technologies, enabling thermal performances to be compared independently of the cold plate part geometries. The lower the thermal resistance, the better the performance of the cold plate. As many cold plates are customized, a range of typical values is shown for each cold plate technology. All cold plate performances are compared using water as the cooling fluid.<\/p>\n<p><a href=\"http:\/\/heatsinks.files.wordpress.com\/2010\/07\/cold_plate_tech_comparison_lytron.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-1310\" title=\"Cold_Plate_Tech_Comparison_Lytron\" src=\"http:\/\/heatsinks.files.wordpress.com\/2010\/07\/cold_plate_tech_comparison_lytron.png?w=300\" alt=\"cold plate technology comparison for thermal management\" width=\"325\" height=\"318\" \/><\/a><\/p>\n<p>Many thermal management applications in electronics require a cold plate to remove the heat from discrete components laid out on a printed circuit board (PCB). In these circumstances, it is more efficient that the liquid does not completely fill the cold plate, but is only transferred to areas that need to be cooled.\u00a0 With this kind of cold plate design, the required volumetric flow rate of the coolant will be significantly lower than if the entire cold plate was filled with liquid.
