Information and Communication Industry - Server Fan Applications

Server is a type of computer that runs faster, has higher load, and is more expensive than regular computers. The server providescomputing or application services to other clients in the network, such as PCs, smartphones, ATMs, and even large devices such as trainsystems. The server has high-speed CPU computing power, ong-term reliable operation, powerful 1/0 external data throughput, andbetter scalability.

On June 14, Intern ational Data Corporation (iDC) released the latest semi annual edge computing market tracking report in China (thesecond half of2022, Data shows that china's edge computing server market will continue to grow significantly in 2022. The totalshipment volume of edge dedicated servers reached 34000 units, a year-on-year increase of 88%- Road rack edge dedicated servers occupya maior market share in edge computing servers, "he development of 5G and Al technology has promoted the growth of edge computingin China. 5G infrastructure and related services have become a national priority for new infrastructure in China, and MEC is positioned asa tool for Chinese operators to bring new services, Edge inteligence based on Al/Ml is the main form of current edge solutions, and thedemand for edge inteligence has not yet been met, With the increase of l'T spending on Al, 5G and other emerging technologies aroundedge scenarios, IDC estimates that China's edge computing server market will reach $11.1 billion in 2027.

Industry Pain Points

High Energy Consumption Issues

With the increasingly powerful functions ofvarious servers, the high energy consumption and highneat electronic components inside the servers continue to increase, and the heat generation insidethe servers also increases significantly; Therefore, the cooling requirements for fans are also morestringent! The improvement of fan performance also brings high power consumption.

High Vibration Issue

With the increasingly powerful functions of various servers, the high energy consumption and high heatelectronic components inside the servers continue to increase, and the heat generation inside theservers also increases signifcantly; Therefore, the cooling requirements for fans are also morestringent! The improvement of fan performance also brings high power consumption.

Optimization of Shengjiu Fan for Server

Design the Best Efficiency Point

The selection of fans needs to be based on the requirements of the system workingpoint. Under the premise of meeting the working point, the best effciency point ofthe fan should be located in the working point area.

Fan Blade Airfoil Design

Optimize parameters such as angle, height, number of blades, circumferentiallength, blade pitch, and clearance of the airfoil.

Flow Field improvement

The eddy current can be reduced by adjusting and optimizing the blade airfoiland the improvement of blade efciency can be expected.

Magnetic Materials and Magnetic Dlux

The motor using neodymium magnets and low iron loss material cores reduces power consumption.

Optimization of Slot Pole Number

By optimizing the number of slots and poles, the switching frequency is reduced, the space of the coil winding is increased, and the slot filling rate is improved.
