An improved solution for cooling a data center is provided. In an embodiment of the invention, a data center design that combines physical segregation of hot and cold air streams together with a data hall variable air volume system is provided. The invention is a data center design that resolves air management issues of re-circulation, bypass and load balance. Bypass is airflow supplied by the cooling units that directly returns without cooling servers. Recirculation airflow is server discharge warm air that returns directly without being cooled. Load balance is supplying the required server airflow. An embodiment includes physical segregation of cold and hot air streams and by providing variable air volume to match server load. Air segregation is done by enclosing the hot aisle end and above the cabinets. The air conditioning system provides variable air volume to the data hall (cold side) to meet server demands. The cooling plant consists of variable-air-volume air-cooling system, which cools air by air free cooling (economizer) and is supplemented with mechanical cooling in the warmer seasons.

A Peltier effect cooling device is formed in combination with an electronic device to form a unique thermal and electrical relationship. An electronic device to be cooled is placed in a serial electrical relationship between at least two thermoelectric couples while simultaneously being in thermal contact with a cold side of the cooler arrangement. The same current which produces the thermoelectric effect in the Peltier thermocouples also drives the electronic device. A balanced effect results as a higher driving current through the electronic device causes greater heating, it is offset by the added cooling due to a greater current in the thermocouples. In addition, a unique spatial arrangement provides improved heat distribution and transfer to a heat sink. Due to the unique shapes of Peltier elements, heat is pulled radially from a heat generating source and distributed at a peripheral region. Shaped Peltier elements are tapered from a small cold area to a large hot area to further magnify the transfer of heat.

Active cooling technologies such as thermoelectrics can be used to introduce thermal “gain” into a cooling system and, when employed in combination with forced flow liquid metal cooling loops, can provide an attractive solution for cooling high heat flux density devices and/or components. In such configurations, it can be advantageous to configure fluid flows to provide heat transfer between hot-side and cold-side flows. For example, it can be desirable to substantially equilibrate temperature of liquid metal flows entering hot-side and cold-side paths. In this way, thermal differential (ΔT) across individual thermoelectric elements can be reduced, thereby improving efficiency of the thermoelectric. Various suitable recuperator designs are described including designs that provide heat exchange with and without mixture of respective flows.
