Description

Technical Field

[0001] The present invention belongs to the technical field of server heat dissipation design, and particularly relates to a device, instrument, mechanism and method for measuring the air pressure in the internal flow field of a server. Background Art

[0002] RV, short for Rotation Vibration, means rotational vibration. The RV performance of a server reflects the internal vibration performance of the server. The higher the RV performance of the server, the better the seismic resistance of the server.

[0003] With the improvement of the intelligence level of servers, servers are increasingly widely used. With the popularization of server applications, the storage capacity requirements for servers are getting larger and larger. Correspondingly, the volume of servers is getting larger and larger, which is inconvenient to use. High-density servers have emerged as the times require. Cooling high-density servers is a design challenge. How to optimize the heat dissipation performance while minimizing the server volume is an issue that always needs attention. The air pressure distribution in the internal flow field of a server is a key parameter in server heat dissipation design. Therefore, obtaining this parameter is crucial for optimizing the heat dissipation performance of the server. In addition, the air pressure distribution in the internal flow field of a server also plays an important role in the RV performance of the server.

[0004] In summary, the air pressure distribution in the internal flow field of a server is an important parameter for assisting heat dissipation design, heat dissipation simulation verification, and solving server RV problems. Obtaining this parameter conveniently and quickly is extremely beneficial for improving the server design level. However, existing devices do not have accurate measurement devices and methods for the air pressure in the internal flow field of a server, and can only estimate it indirectly through empirical evaluation, simulation calculation, etc., and cannot accurately guide the design.

[0005] This is the deficiency of the existing technology. Therefore, it is very necessary to provide a device, instrument, mechanism and method for measuring the air pressure in the internal flow field of a server to address the above-mentioned defects in the existing technology.
