Problems solved by technology

In order to solve the heat dissipation problem of the server, the use of multiple high-speed fans to improve heat dissipation will become the main trend of server heat dissipation. However, as the fan speed increases, the dynamic balance performance of the fan will decrease, resulting in problems when multiple fans are used at the same time. resonance phenomenon

Embodiment Construction

[0015] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0016] The present invention mainly takes the design specifications of the fan frame and the vibration transmission mode as the theoretical support points, simulates the rotation of the fan when the server is running through an external fan control panel, and completes the resonance test of the server through reasonable and effective testing methods and testing tools. Concrete invention content can be divided into following two aspects:

[0017] a) Using an external fan control panel, by adjusting the fan PWM control signal to adjust the operation of the fan, the test can be completed when the server system is not turned on, reducing unnecessary workload and power consumption of the server. To the role of energy saving and environmental protection;

[0018] b) Measure and display the vibration of the server in real time by pasting the sensor, which reduces t...

Abstract

The invention provides a server resonance weakening method which employs a high-precision dynamic signal analyzer for multi-contact measurement of vibration conditions of each part and rigid joints. Capturing vibration source positions and vibration transmission modes is the key point, and in order to guarantee reliability and precision of measured data, a vibration sensor needs to be attached to a vibration source as far as possible to capture the vibration conditions of parts in real time. Further, vibration of three positions in different directions are measured at the same time to accurately measure from multiple space angles and feed system and part vibration conditions back, so that reliability of measurement data can be guaranteed. The rotation speed of a fan is simulated and adjusted through a fan speed adjusting control panel when a server is in different power consumption, operation conditions of the fan are directly reflected by means of LED real-time display, and a system and part vibration test can be completed without electrifying the server, so that testing workload is reduced, energy conservation and environment protection are realized, and operating cost is reduced.

Description

technical field [0001] The present invention relates to computer server technology, specifically, using a fan speed control panel and a high-precision testing instrument to solve the problem of server system resonance or a method of reducing server resonance through a reasonable and efficient testing method. Background technique [0002] In today's server products, in order to meet the performance improvement, the system configuration is also continuously improved, which will make it more difficult for the server to dissipate heat. In order to solve the heat dissipation problem of the server, using multiple high-speed fans to work at the same time will become the main trend of server heat dissipation. However, as the fan speed increases, the dynamic balance performance of the fan will decrease, resulting in resonance when multiple fans are used at the same time. [0003] On the other hand, vibration has the greatest impact on the server, which is mainly composed of magnetic...
