Description

Technical Field

[0001] The present invention belongs to the technical field of server heat dissipation design, and in particular relates to a device, instrument, mechanism and method for measuring wind speed in a flow field within a server. Background Art

[0002] RV stands for Rotational Vibration. A server's RV performance reflects the server's internal vibration. The higher the server's RV performance, the better the server's seismic resistance.

[0003] As server intelligence increases, server applications become increasingly widespread. This widespread use of servers also increases the demand for greater storage capacity. Consequently, servers become larger and more inconvenient to use, leading to the emergence of high-density servers. Cooling high-density servers presents a design challenge. Optimizing cooling performance while minimizing server size is a constant concern. The velocity distribution within the server is a key parameter in server cooling design, making its determination crucial for optimizing server cooling performance. Furthermore, this velocity distribution plays a crucial role in server RV performance.

[0004] In summary, the velocity distribution within a server is a crucial parameter for assisting with cooling design, simulation verification, and resolving server RV issues. Quickly and easily obtaining this parameter is extremely beneficial for improving server design. However, existing equipment and methods lack accurate measurement of wind velocity within servers, requiring only indirect estimations based on empirical evaluation and simulation calculations, which cannot accurately guide design.

[0005] This is a shortcoming of the existing technology. Therefore, in order to address the above-mentioned defects in the existing technology, it is very necessary to provide a device, instrument, mechanism and method for measuring the wind speed of the flow field in a server. Summary of the Invention

[0006] In view of the defect that the above-mentioned existing equipment in the prior art does not have accurate measurement equipment and methods for the flow field wind speed in the server, and can only be estimated by indirect methods such as experience evaluation and simulation calculation, and cannot accurately guide the design, the present invention provides a flow field wind speed measurement device, instrument, mechanism and method in the server to solve the above technical problems.

[0033] The hanging part adopts a Z-shaped structure, and the upper and lower edges of the Z-shaped structure are provided with hanging edges that are buckled with the sliding rod;

[0034] The sleeve portion is fixedly arranged at the lower bottom edge of the Z-shaped structure and is perpendicular to the lower bottom edge of the Z-shaped structure;

[0035] The mounting rod of the anemometer is arranged in the sleeve portion and can move up and down along the sleeve portion.

[0036] In a fourth aspect, the present invention provides a method for measuring wind speed in a flow field within a server, comprising the following steps:
