Design and Simulation of the Evaporator for Cooling System of the Blade Server

Blade servers are stripped down computer servers with a modular design optimized to minimize the use of physical space. Whereas a standard rack-mount server can function with (at least) a power cord and network cable, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. One of the major features of the blade serve is its strong calculation capability which is related with the dynamical powers, the heat outputs, and the temperatures at which it could still work. Now the cooling technology used in the traditional servers has become one of the most important technologies to restrict the development of the blade serves. So study and design an appropriate cooling system based on the characteristics of its heat dissipation is an urgent work to do in order to develop the blade servers. The effective refrigerant system which has high efficiency heat exchangers is designed according to the limited space behind the blade enclosure, which can hold multiple blade servers. This refrigerant system can dissipate the heat effectively to ensure the normal work of all the blade servers. The CFD software have been used to simulate the cooling effect of the system and given valuable information to improve the design.
