Wind scooper, heat dissipation device and server

Abstract

The invention relates to the technical field of servers, in particular to a wind scooper, a heat dissipation device and a server. The wind scooper comprises a first scooper body and a second scooper body, and the first scooper body is provided with a wind guiding cavity, an air inlet and an air outlet; and the second cover body is arranged on the first cover body, a noise reduction cavity is defined by the second cover body and the first cover body, a plurality of circulation openings are formed in the first cover body defining the noise reduction cavity, and the noise reduction cavity communicates with the air guide cavity through the circulation openings. According to the wind scooper, the first scooper body and the second scooper body are matched with each other to define the noise reduction cavity, the noise reduction cavity communicates with the wind guide cavity through the circulation opening, energy is consumed by the noise reduction cavity in the process that noise is transmitted at the wind scooper, and the effect of reducing the noise is achieved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to an air guide cover, a cooling device and a server. Background technique [0002] In recent years, data centers, as one of the representatives of new infrastructure, have been widely constructed and applied, providing growth momentum for all walks of life. In order to maximize the use of resources, data centers are often operated at close to full load, which consumes a lot of power and generates huge noise. Noise will adversely affect the health of the operation and maintenance personnel of the data center, and it is easy to exceed the national environmental standards. Therefore, noise reduction treatment is imperative. [0003] The noise of the data center mainly comes from the server, and the noise of the server mainly includes aerodynamic noise and electromagnetic noise. Aerodynamic noise belongs to broadband noise, which exists in various frequency bands. Electromagnetic noi...

AI Technical Summary

Problems solved by technology

Passive noise reduction technology is to absorb noise energy through sound-absorbing materials in the process of noise transmission to achieve the purpose of noise reduction; however, a large number of sound-absorbing materials need to be arranged, and the design and production are relatively complicated, which is not suitable for large-scale applications

Active noise reduction technology is to arrange noise sensors in the server to detect the amplitude, frequency and phase of the noise, and the speaker outputs the sound with the same frequency, equal amplitude and opposite phase to achieve the purpose of noise reduction; the noise reduction method is too complicated and the production cost High, need to consume extra power
