Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of server heat dissipation devices, and in particular to a server heat dissipation device using a high-speed fan. Background Art
[0002] A server is an IT device that provides computing power and runs software applications in a network environment. Designed to perform specific tasks, such as data storage, website hosting, and email services, servers typically operate 24 / 7 to provide services to other computers or devices. Servers are typically capable of responding to service requests, providing services, and guaranteeing service. Server cooling is critical to ensuring stable server operation. Servers generate significant heat during operation. Failure to dissipate heat promptly can cause hardware damage or performance degradation.
[0003] Traditional cooling methods and their corresponding advantages and disadvantages are as follows: Water Cooling: This system transfers heat to the outside through a water cooling system, offering high efficiency and suitable for high-power servers, but requires regular maintenance and high costs. Liquid Cooling: This includes cold plate, spray, and immersion cooling methods, suitable for high-density and high-performance servers, but requires professional installation and maintenance, resulting in high costs. Heat Pipe Cooling: This system conducts heat through metal pipes, suitable for servers with moderate power consumption, but is slow and inefficient. Air Cooling: This system uses fans to expel hot air from the chassis. This is the most common cooling method, offering simplicity and low cost, but is inefficient and lacks effective heat dissipation, making it suitable for general servers. Furthermore, traditional air cooling uses external rotor fans secured to the server with clips. When the external rotor motor runs at high speed, the motor's vibration is directly transmitted to the server chassis, causing vibration and damaging electronic components. Traditional fans have low heat dissipation capacity and cannot meet the rapid cooling requirements of high-power components. This is especially true when multiple motors are used simultaneously, as they operate under the same operating conditions and generate vibrations at the same frequency, which can easily cause chassis resonance and damage electronic components.
