... Abstract Submerging a cluster of servers inside a large tank is the customary way of employing single-phase immersion cooling. But this approach requires a complete renovation of existing air-cooled infrastructure. A practical approach to convert an air-cooled data center to immersion cooled...

... technologies since the 1980s. Major data and cloud providers are actively deploying liquid-cooled data center infrastructure due to rising computational demands. Liquid to liquid heat exchangers used in liquid-cooled data centers is also referred to as coolant distribution units (CDUs). Most of these CDUs...

.... Therefore, it is necessary to look for an alternative green refrigerant that can be adopted in the system without significantly impacting its performance. Preliminary results showed that R1234yf is the most appropriate replacement for R134a in two-phase rack-level cooling systems. data center two...

... Abstract Thermal predictions in data centers have been utilized to reduce the electric consumption of thermal equipment in data centers. While most of the optimization of data center temperature has been performed through the utilization of Computational Fluid Dynamics (CFD) and heuristic...

... Abstract In today’s world, most data centers have multiple racks with numerous servers in each of them. The high amount of heat dissipation has become the largest server-level cooling problem for the data centers. The higher dissipation required, the higher is the total energy required to run...

... for the challenges of on substrate process and reliability, meanwhile simulation is performed for stress prediction. In addition, possible solutions from material and process are discussed and studied. HPC data center cloud computing chip module UF encapsulation reliability HIGH PERFORMANCE COMPUTING...

... Abstract Modern-day data center administrators are finding it increasingly difficult to lower the costs incurred in mechanical cooling of their IT equipment. This is especially true for high-performance computing facilities like Artificial Intelligence, Bitcoin Mining, and Deep Learning, etc...

... Abstract Efficient cooling of data center infrastructure is an important way to reduce total energy consumption. Containment, with separation of hot and cold airflows has allowed significant increase in efficiencies. However, balancing the airflow, so that IT equipment in an aisle only receives...

... Abstract This study highlights experimental challenges of setting up a computational fluid dynamics (CFD) model of a 180-m 2 small-size high-performance computing (HPC) data center (DC) in a university campus and the validation procedure leading to a reasonably accurate CFD model...

... Reducing the energy consumption of a data center has recently become important because the data center market is rapidly expanding. We developed the “IT-facility linkage system” to deal with this energy saving requirement. This system reduces the amount of energy consumed in a data center...

... 12 01 2010 With the ever increasing heat dissipated by IT equipment housed in data centers it is becoming more important to project the changes that can occur in the data center as the newer higher powered hardware is installed. The computational fluid dynamics (CFD) software...

... Recent work has proposed an exergy-based strategy to achieve optimal system-wide performance via localized control of individual data center thermal management components. This paper presents the results of a case study where the proposed approach is applied to a data center with two rows...

... current state of art in thermal management are computer room air ditioning (CRAC) units that deliver cold air to the cabinets ugh perforated tiles placed over an under-floor plenum. cooling costs of data centers represent up to 40% of the rgy consumption of center operation [2], corresponding to a ificant...

... 03 04 2009 In raised-floor data centers, distributed leakage flow—the airflow through seams between panels on the raised floor—reduces the amount of cooling air available at the inlets of the computer equipment. This airflow must be known to determine the total cooling air requirement...

... and correspondingly increased air flowrate the chilled air flow supplied either through data center raised floor perforated tiles or diffusers for non raised floors is not sufficient to match the air flow required by the datacom racks. In this case some of the hot air exhausting the rear of a rack can return...

... 03 04 2009 As heat dissipation in data centers rises by orders of magnitude, inefficiencies such as recirculation will have an increasingly significant impact on the thermal manageability and energy efficiency of the cooling infrastructure. For example, prior work has shown...

... 03 04 2009 The heat dissipated by large servers and switching equipment is reaching levels that make it very difficult to cool these systems in data centers or telecommunications rooms. Some of the highest powered systems are dissipating upwards of 4000 watts/ft 2 (43,000 watts/m 2...

... 03 04 2009 Data center equipment almost always represents a high expenditure capital investment to the customer, and is often operated without any down time. Data com equipment is typically designed to operate at a rack air inlet temperature of between 10 and 35°C, and a violation...
