Embodiment Construction

[0050] Rack-mounted electronic equipment, such as computing equipment, networking equipment, and storage equipment, can generate significant amounts of heat due to the nature of their operation. This heat needs to be dissipated to help prevent damage to the electronics and to enhance the operation and lifespan of the electronics. Data centers have traditionally utilized front-to-back air convection cooling to cool rack-mounted electronics. But device densities have increased to the point where thermal shadowing renders these cooling systems unusable in many environments. Energy efficiency and operating cost considerations also consider air cooling to be problematic.

[0051] By way of example, in order to meet device temperature requirements using forced air cooling, a significant amount of heat needs to be handled by heat sinks and fans. Heat sinks and fans are significant hindrances to system board and processor layout. As an example, the volume of space for an air-cooled...

Abstract

A heat dissipation system and method are disclosed. An example method includes removing heat from the frame components via a heat spreader. The method also includes applying pressure at a fluid-cooled thermal bus bar on the rack system to form a thermally conductive dry-break interface and create a thermal path between the thermal spreader and the fluid-cooled thermal bus bar.

Description

technical field [0001] The invention relates to a heat dissipation system and a heat dissipation method for heat generating equipment. Background technique [0002] Various thermal management systems can be used in heat-generating devices, such as computer systems and electronic devices. A simple thermal management system consists of a heat sink and cooling fans. A heat sink is positioned in contact with the heat-generating electronic components to transfer that heat to the surrounding air. Cooling fans may be positioned to blow air across the heatsink to dissipate heat into the surrounding environment. [0003] While cooling fans can often be effectively implemented in stand-alone equipment, large data centers typically have many heat-generating devices in a dense layout. In this environment, "heat shadowing" remains an issue. Thermal shadowing is caused by migrating heat from adjacent or "upstream" equipment. For example, a fan that blows heat away from one device may...
