Introduction As electronic products become more sophisticated and design margins tighten, defining the thermal management strategy early in the design cycle is vital to ensure a cost-effective design for the level of heat dissipation. Optimizing the cooling system for an electronic product can involve juggling many design parameters, such as airflow rate, fan and vent … [Read more...]
Review of Low Profile Cold Plate Technology for High Density Servers
Introduction Water cooling of computers was introduced more than twenty years ago, but had disappeared from the mainstream by the mid 1990s. The conversion of chip technology from bipolar to CMOS (complementary metal oxide semiconductor) was the main reason. As chip powers continue to increase, water cooling appears likely to become mainstream again. In the current market, the … [Read more...]
ASHRAE Committee Formed to Establish Thermal Guidelines for Datacom Facilities
Introduction The environment of every data center is complex and unique. Air currents within the data center have hot and cold air streams colliding, cold air exhausting upward from perforated tiles, hot air streams exhausting from tops and the rear of servers and storage racks. Not only are these air circulation patterns extremely complex, they can also be transient in nature … [Read more...]
Estimating Temperatures in an Air-cooled Closed Box Electronics Enclosure
Introduction In the majority of air-cooling applications, openings or vents are provided in the enclosure or box in which the electronic components are housed. The required cooling air is drawn in from outside the box by fans or blowers. In some applications, however, there may be airborne particulates or other substances in the air that would be injurious to the electrical … [Read more...]
Server Design Challenges for the High-heat-load Internet Data Center
Introduction Microprocessor and system thermal management are linked to facility cooling: power dissipation and cooling techniques employed at one end of the size scale have cascading impacts at the other extreme (Figure 1). For example, ineffective airflow distribution or insufficient underfloor static pressure in a data center can reduce the supply airflow rate from … [Read more...]
