Description

TECHNICAL FIELD

[0001] The application relates to the technical field of server heat dissipation, in particular to a server device stable in operation. BACKGROUND

[0002] A server is a high-performance computing device specially used for providing network services, data processing and storage functions, and is widely used in key places such as data centers and enterprise computer rooms. Due to its long-time stable operation and large heat load, the server shell is usually provided with a heat dissipation structure based on a circulating fan to ensure the stable temperature of the internal components. In particular, in the industrial and scientific research application scenarios of high-speed data simulation, thermodynamic modeling or precise control of liquid colored metals, liquid noble metals or liquid rare earth metals, the server often needs to process high-intensity operation and data interaction tasks, which puts higher requirements on heat dissipation and system stability. In order to prevent dust in the air from entering and adhering to the radiator or mainboard, affecting the heat dissipation efficiency and operation reliability, a dust blocking structure is usually provided on the shell to realize the dual control of air circulation and dust prevention, thereby effectively improving the service life and stability of the server in complex application environments.

[0003] Some heat dissipation fans provided in the server shell in the prior art are usually provided with a dust screen at the air inlet. When it is necessary to disassemble and clean the dust screen, the air inlet of the heat dissipation fan is exposed to the unfiltered external air. Dust, particles and fiber impurities in the air are easily sucked into the fan and deposited on the mainboard, power supply and heat dissipation fins, resulting in a significant decrease in heat dissipation efficiency, and even causing electrical short circuit and system instability. At this time, in order to prevent dust from entering, it is necessary to stop the operation of the heat dissipation fan, but the demand for heat dissipation of the server still exists in the running state. The stoppage of the fan causes the internal heat to be unable to be dissipated in time, resulting in the risk of overheating of the equipment and seriously affecting the stability and service life of the server, forming a contradictory problem between heat dissipation protection and dust protection.
