Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a method, a device and a medium for matching noise performance of a server cooling fan.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
At present, the industry mainly adopts two modes to obtain the actual noise value of the server cooling fan, one mode is that the server is combined with the alternative fans one by one after the whole machine is sampled to carry out the whole machine noise test, the process is time-consuming and labor-consuming, and the research and development cost and the design period of an enterprise are obviously increased; the other method is fan fluid simulation and server sound transmission simulation, and the flow needs to be additionally provided with a high-performance computing cluster and still has a short computing period, so that the time period requirement of rapid fan model selection in the initial design stage is difficult to meet. In view of the above problems, the embodiments of the present application provide a method for quickly matching noise performance of a server and a cooling fan at an initial stage of a scheme design, so that a cooling fan with a low actual noise value, which does not resonate with an acoustic cavity in an alternative scheme, can be quickly screened out. Fig. 1 is a flowchart of a noise performance matching method for a server cooling fan according to an embodiment of the present disclosure. As shown in fig. 1, the method comprises:
s10: and acquiring complete machine geometric data of a target server containing all the components, and acquiring working rotating speed information of the alternative fan.
S11: establishing a numerical analysis model of an internal acoustic cavity of the target server according to the geometric data of the whole machine; wherein the internal acoustic cavity characterizes an air-filled spatial region in the target server.
S12: and generating the internal sound cavity mode of the target server according to the data analysis model.
S13: and acquiring a target fan in the alternative fans through frequency peak staggering according to the working rotating speed information and the internal sound cavity mode so as to match the target fan with the target server.
It will be appreciated that the target server is the server that needs to have matching of the cooling fan noise performance. The server generally includes a chassis, a heat dissipation fan, a hard disk, a Central Processing Unit (CPU), a CPU heat sink, an air guiding cover, a memory, a display card, a motherboard, and a power supply. Since the server cooling fan usually works in a server including all the above components, when acquiring geometric data of a target server, it is necessary to acquire complete geometric data of the target server including all the components. The geometric data is a three-dimensional model in proportion to or consistent with the size of a real object, and can be drawn by adopting any drawing software, such as CREO Parametric. For obtaining the geometric data, ANSYS SPACECLAIM is available, which is a new generation of 3D high-efficiency numerical modeling software, and is widely used in the field of international industrial numerical analysis. It should be noted that, the embodiment does not limit the specific acquisition manner of the geometric data, and is determined according to the specific implementation.
Further, when the complete machine geometric data of the target server including all the components is obtained, the working rotating speed information of the alternative fan needs to be obtained. The alternative fans are all fans that match the cooling fan noise performance. It should be noted that the alternative fan must be one that can be adapted to the target server. The working speed information of the alternative fan can be obtained by extracting the relevant speed data of the alternative fan.
In order to realize the noise performance matching of the cooling fan, a numerical analysis model of the acoustic cavity inside the target server is further established according to the geometric data of the whole machine, and the numerical analysis model is used for representing the characteristics of the acoustic cavity inside the server. It is noted that the internal acoustic cavity represents the air-filled spatial region in the target server. In the actual development process, a designer generates geometric data of the server containing all the detail features according to development requirements, and then the geometric data is handed to an analysis engineer for performance evaluation and analysis, and if the geometric data is directly calculated, the process is complex. In order to simplify the subsequent calculation process, in specific implementation, the geometric data of the whole server can be simplified and the like at the beginning of establishing the numerical analysis model, so that the overall calculation amount is reduced. In this embodiment, specific data of the geometric data of the whole machine is not limited, and may be geometric data including all detailed features of the target server, or may be simplified geometric data, which is determined according to a specific implementation situation.
After the data analysis model is obtained, the internal acoustic cavity mode of the target server needs to be generated according to the data analysis model. It should be noted that the acoustic cavity mode characterizes the vibration of the sound pressure of the air inside the server at its natural frequency. Compared with fan fluid simulation calculation and server sound transmission calculation, the sound cavity modal calculation reduces the flow of fluid modeling and simulation calculation, and also omits the calculation of a gas wave equation in sound transmission simulation, so that fewer calculation resources and calculation periods are needed. Although the actual contrast is affected by various factors such as detail characteristics, model quality, parameter settings, and the like, roughly speaking, the acoustic cavity modality has a smaller CPU usage rate, memory usage rate, and computation time than the fan fluid simulation computation and the server acoustic propagation computation for the same evaluation object. Therefore, compared with the complete fan fluid simulation calculation and server sound propagation calculation processes, the process of adopting the acoustic cavity modal calculation can greatly reduce the calculation resource requirement and greatly shorten the calculation period.
And after the internal sound cavity mode is obtained, acquiring a target fan in the alternative fan through frequency peak staggering according to the working rotating speed information and the internal sound cavity mode. The performance of all the alternative fans can be screened in a frequency peak staggering mode, and the target fan with the best noise performance in all the alternative fans is obtained. In this embodiment, a specific acquiring process of the target fan is not limited, and is determined according to a specific implementation situation.
In the embodiment, the whole geometric data of the target server containing all the components is obtained, and the working rotating speed information of the alternative fan is obtained; establishing a numerical analysis model of an internal acoustic cavity of the target server according to the geometric data of the whole machine; wherein the internal acoustic cavity characterizes an air-filled spatial region in the target server. Generating an internal acoustic cavity mode of the target server according to the data analysis model; and acquiring a target fan in the alternative fans through frequency peak staggering according to the working rotating speed information and the internal sound cavity mode so as to match the target fan with the target server. Therefore, according to the scheme, the numerical analysis model of the sound cavity in the target server is established, the resonance of the sound cavity of the server and the fan blades is avoided by using the frequency peak shifting principle, and the fan with the optimal noise performance after being combined with the server is quickly matched at the initial stage of scheme design. The process that all the alternative fans are required to be installed in the server one by one to carry out noise test testing is omitted; compared with the fan fluid simulation and server sound propagation simulation process additionally provided with the high-performance computing cluster, the method has the advantages that the calculation period is shorter, the research and development efficiency is effectively improved, the research and development period is shortened, and the research and development cost is reduced.

In order to simplify the subsequent calculation process of the numerical analysis model, as a preferred embodiment, in the specific implementation, at the beginning of establishing the numerical analysis model, the geometric data of the whole server is simplified according to a preset simplification rule, and simplified geometric data is obtained. Wherein, the preset simplifying rule needs to simplify or discard detail features and components which have small influence on the analysis result, but retain important features and components which have significant influence on the analysis result. After the geometric data is properly corrected, the reverse envelope extraction of the internal space is carried out by taking the chassis outline as the boundary, and then the simplified geometric data model of the acoustic cavity can be obtained. The preset simplification rule in this embodiment is not limited, and is determined according to specific implementation conditions.
After the simplified geometric data is obtained, the simplified geometric data needs to be further subjected to mesh division according to a preset mesh division rule to obtain mesh data. Namely, the simplified geometric data is divided into a plurality of small grid cells, and the quality of the generated grid cells directly influences the quality of the subsequent analysis result. Specifically, for the acoustic cavity model, three-dimensional volume unit meshing occupying spatial positions needs to be performed, and the volume unit is preferably a regular hexahedron. The final grid cells need to properly express the space occupation of the original geometric model, and the quality of the grid cells needs to satisfy certain examination conditions. In this embodiment, the preset mesh division rule is not limited, and is determined according to a specific implementation situation.
Further, parameter setting is carried out on the grid data according to a preset parameter setting rule to obtain a finite element method numerical analysis model of the internal sound cavity mode of the server. It should be noted that, the server acoustic cavity parameters generally include: material acoustic property parameters, analysis frequency interval range, acoustic boundary conditions, and the like. The material acoustic property parameters are a set of acoustic performance parameters which accurately express that the gas or noise reduction material is irrelevant to size or constraint; analyzing the frequency range to be the frequency range concerned in the practical engineering application; the acoustic boundary condition refers to a parameter of a change law of a specific variable or its derivative on the boundary of the sound field solution region. And finally, setting the parameters to finally obtain a finite element method numerical analysis model of the internal acoustic cavity mode of the server so as to conveniently obtain the internal acoustic cavity mode subsequently.
In the embodiment, the geometric data of the whole machine is simplified according to a preset simplification rule to obtain simplified geometric data; meshing the simplified geometric data according to a preset meshing rule to obtain mesh data; and carrying out parameter setting on the grid data according to a preset parameter setting rule to obtain a finite element method numerical analysis model of the internal sound cavity mode of the target server, so that the establishment of the numerical analysis model is realized, and the subsequent calculation process is simplified.
On the basis of the above-described embodiment:
as a preferred embodiment, generating the internal acoustic cavity modality of the target server according to the data analysis model includes:
and solving a rectangular equation of the numerical analysis model according to a preset analysis algorithm rule to generate an internal sound cavity mode of the target server.
As a preferred embodiment, in this embodiment, the rectangular equation of the numerical analysis model is solved according to a preset analysis algorithm rule to generate the internal acoustic cavity mode of the target server. The solving process may be performed by ANSYS Acoustics, and is not limited in this embodiment and is determined according to a specific implementation. In addition, the preset analysis algorithm rule in this embodiment is not limited, and is determined according to specific implementation situations.
As a preferred embodiment, the internal acoustic cavity mode is a first-order mode frequency of the internal acoustic cavity. The first-order mode appears when the excitation frequency of the external force is equal to the natural frequency (first order) of the object, and the vibration mode of the object is called a first-order mode or a main mode.
In this embodiment, the rectangular equation of the numerical analysis model is solved according to the preset analysis algorithm rule, and the internal acoustic cavity mode is the first-order mode frequency of the internal acoustic cavity, so that the generation of the internal acoustic cavity mode of the target server is realized.
On the basis of the above-described embodiment:
as a preferred embodiment, acquiring the target fan in the alternative fans through frequency offset peak according to the working rotating speed information and the internal sound cavity mode comprises the following steps:
acquiring fan blade passing frequency according to the working rotating speed information and the number of the rotor fan blades;
acquiring a difference value between the passing frequency of the fan blade and the first-order modal frequency;
and acquiring the alternative fan corresponding to the difference value with the largest absolute value as the target fan.
The specific acquisition process of the target fan in the above embodiment is not limited, and is determined according to specific implementation situations. As a preferred embodiment, in this embodiment, first, the blade passing frequency is obtained according to the operating rotational speed information and the number of rotor blades; the blade passing frequency is converted according to the operating speed of the cooling fan and the number of the rotor blades. For example, the operating speed of the cooling fan is 30000 rpm, 5 blades are arranged on the rotor, and the passing frequency of the fan blades is 2500 Hz.
Further, acquiring a difference value between the passing frequency of the fan blade and the first-order modal frequency; and acquiring the alternative fan corresponding to the difference value with the largest absolute value as the target fan. That is, the passing frequency of the fan blades of all the alternative fans is different from the first-order modal frequency of the acoustic cavity, and the heat dissipation fan with the largest absolute value is the optimal result of noise performance matching. In practical applications, this process may be implemented by an execution program compiled in the PYTHON language, or other compiling languages may be selected, which is determined according to specific implementation situations and is not limited in this embodiment.
In the embodiment, the fan blade passing frequency is obtained according to the working rotating speed information and the number of the rotor fan blades; acquiring a difference value between the passing frequency of the fan blade and the first-order modal frequency; and acquiring the alternative fan corresponding to the maximum absolute value difference value to serve as the target fan, so that the acquisition of the cooling fan with the optimal noise performance matching is realized.

It will be appreciated that in practice, only a portion of all of the fans in the fan component library may be applied to the target server due to size, ventilation, supplier supply conditions, etc. Therefore, applicable fan models need to be screened out as alternative fans according to preset limiting conditions. When entering the database, the fan can simultaneously enter the specification of the fan, wherein the specification comprises working rotating speed data. And extracting the relevant rotating speed data of the fan meeting the limit condition to obtain the working rotating speed information of the alternative fan.

It should be noted that the preset limiting condition in this embodiment is determined by the target server, and the preset limiting condition is not limited in this embodiment, and is determined according to specific implementation situations.
In the embodiment, model parameters of all fans are obtained; judging whether the model parameters meet preset limiting conditions of a target server or not; if yes, the fan is used as the alternative fan, and the alternative fan of the target server is obtained.
On the basis of the above embodiment, as a preferred embodiment, after acquiring the target fan in the alternative fans through frequency offset peak according to the operating speed information and the internal acoustic cavity mode, as shown in fig. 2, the method further includes:
s17: and outputting the model parameter of the target fan.
