The combination of pump top and reservoir has been designed to fit into compact servers and workstations. Depending on the in-stallation method, the Eisstation 80 DC-LT even fits into 2U server housings.What is the special feature?Thanks to the compact dimensions and the variable mounting options, the Eisstation 80 DC-LT is suitable for very compact water-cooled systems. The optionally available DC-LT pump is also available in different performance levels and can easily operate smaller water loops. The entire DC-LT Eisstation is made of acetal and is extremely resistant and durable.What are the mounting options?The 80 DC-LT Eisstation is supplied with an adhesive Velcro mat and special feet. The Velcro mat allows the lowest installation position and is also the easiest to use. A part of the Velcro mat is simply stuck to the desired installation location and the other side to the floor of the Eisstation 80 DC-LT. This means the positioning is completely down to you. The enclosed feet were designed for different mounting possi-bilities. The installation height can be varied. In addition, installation at an angle of 30 or 90° is also possi-ble. In addition, decoupling feet are included with the accessories to reduce the noise of the already quiet pump further.Installation of the pump and filling!The fill port has a diameter of 25 mm and has been designed to be particularly large so that filling can be done easily by hand. This means that the water loop can also be filled without a filling aid such as a spray bottle or funnel. To mount the pump a base plate must be removed, this is only held in place by two screws. Then the O-ring supplied with the DC-LT pump is inserted and the pump is put on and fastened with the two screws. The cable of the pump then just needs to be led through the cable opening.IN and Out?The Eisstation 80 DC-LT consists of a pump top and a reservoir. If both components are used, the IN is located on the side of the reservoir. The OUT is also located on the side of the pump top. You can vary the locations a little by dismantling both parts from each other and simply reassembling the reservoir by turning it 90 or 180°. If the reservoir is not used, the pump top has an additional IN on the opposite side of the OUT.Small, compact and versatile, this is the Eissstation 80 DC-LT from the Alphacool Enterprise Solution se-ries.。

----------Induction Currents from CircularCoilsIntroductionA time-varying current induces a varying magnetic field. This field induces currents in neighboring conductors. The induced currents are called eddy currents. The following model illustrates this phenomenon by a time-harmonic field simulation as well as a transient analysis, which provides a study of the eddy currents resulting from switching on the source.Two current-carrying coils are placed above a copper plate. They are surrounded by air, and there is a small air gap between the coils and the metal plate. A potential difference provides the external source. To obtain the total current density in the coils you must take the induced currents into account. The time-harmonic case shows the skin effect, that is, that the current density is high close to the surface and decreases rapidly inside the conductor.Model DefinitionE Q U A T I O NTo solve the problem, use a quasi-static equation for the magnetic potential A :σ-∂--A ---- + ∇ × (μ–1μ–1∇ × A ) = σV coi -l∂t0 r 2πrcoilHere μ0 is the permeability of vacuum, μr the relative permeability, σ the electric conductivity, and V coil the voltage over one turn in the coil. In the time-harmonic case the equation reduces to–1 –1V= ----------- j ωσA + ∇ × (μ0 μr ∇ × A ) σ 2πrF O R C E SThe total electromagnetic force acting on region of space Ω can beobtained by integrating Maxwe ll’s stress tensor on the delimiting boundary ∂Ω:F =T n dS∂ΩThe Force Calculation feature automatically performs the integral along the boundaries of the desired region, considering also the axisymmetric geometry of the problem. The computed force will be available in results processing as a global variable.Results andDiscussionIn the time-harmonic regime, the varying magnetic field induces electrical currents in the metallic plate. The currents, in turn, act as sources of an opposing magnetic field “shiel d ing” the plate from the magnetic field. As a result of this phenomenon, the region in which electrical currents are generated is confined in proximity of the surface and reduces in size with increasing frequency. Figure 1 and Figure 2 show the induced current density at 10 Hz and 300 Hz, respectively.In this model, a time-domain study is performed to investigate the step response of the system. Figure 3 displays a snapshot of the induced current density and magnetic flux density for the transient solution in a combined surface and arrow plot.Finally, Figure 4 shows the total axial force between the coils and the plate as a function of time computed by the Force Calculation feature. For the chosen current direction, the force is repulsive(negative).Figure 1: The ϕcomponent of the induced current density for the time-harmonic solution plotted together with a contour plot of the magnetic vector potential at a frequency of10 Hz.Figure 2: Plot of the same quantities at a frequency of 300 Hz.Figure 3: Snapshot of the induced current density (surface plot) and the magnetic flux density (arrow plot) during the transient study.Model Library path:ACDC_Module/Inductive_Devices_and_Coils/coil_above_plateModeling Instructions—Frequency DomainFrom the File menu, choose New.N E W1 In the New window, click the Model Wizard button.M O D E L W I Z A R D1In the Model Wizard window, click the 2D Axisymmetric button. 2In the Select physics tree, select AC/DC>Magnetic Fields (mf). 3Click the Add button.4Click the Study button.5In the tree, select Preset Studies>Frequency Domain.6Click the Done button.G E O M E T R Y 1Square 11In the Model Builder window, under Component 1 right-click Geometry 1 and choose Square.2In the Square settings window, locate the Size section.3In the Side length edit field, type .4Locate the Position section.

Eddy Currents in a CylinderIntroductionTo help you understand how to create models using the AC/DC Module, this section walks through an example in great detail. You can apply these techniques to all the models in this module, other optional modules, or even the many models that ship with the base COMSOL Multiphysics package.The example model concerns an AC coil surrounding a metal cylinder (core), and the coil induces eddy currents in the cylinder. It illustrates how to use the Coil Domain features to model the coil in different ways.Model DefinitionDue to the cylindrical symmetry of the problem, a 2D axisymmetric geometry is used.The modeling plane is the rz-plane; the horizontal axis represents the r-axis, and the vertical axis represents the z-axis. In this plane, the core appears as a rectangle and the coil as a circle. To obtain the actual 3D geometry, revolve the 2D axisymmetricgeometry about the z-axis.The physics interface used in this model is Magnetic Fields interface, with a Frequency Domain study type. The fundamental equations involved are explained in thefollowing sections.D O M A I NE Q U A T I O N SThe dependent va ria ble in this physics interfa ce is the a zimutha l component of magnetic vector potential, A, which, in frequency domain, obeys the relation:(1)where ω is the angular frequency, σ is the electric conductivity, μ is the permeability, εis the permittivity, and denotes the current density due to an external source. One wa y to define the current source is to specify a distributed current density in the right-hand side of the above equation. This current density gives rise to a current I as defined by:(2)B O U N D A R YC O ND I T I O N SThis model requires boundary conditions for the exterior boundary and the symmetry xis, a nd to specify bounda ry currents when a pplica ble. The physics interfa ce a utoma tica lly a pplies a bounda ry condition corresponding to zero ma gnetic flux through the exterior bounda ry, by setting the vector potentia l to zero. On the symmetry axis, a suitable symmetry boundary condition is applied.C O I L G R O U PD O M A I N SThe Magnetic Fields interface provides features, called Coil Group Domain, that can conveniently be used to model coils in 2D and 2D axisymmetric geometries.The Single-Turn Coil Domain models a single winding of a homogeneous metallic conductor, in which the current density ca n be non-uniform, due to the a xia l symmetry or skin effect. Note that applying the Single-Turn Coil Domain feature to multiple domains effectively consists in having multiple coils in parallel.The Multi-Turn Coil Domain is used to model a great number of tiny wires wound together. In this approximation, the current density is uniform, and no conduction currents appear in the domain. From this follows that the material used to model this domain should reflect the properties of the insulator covering the wires, rather than of the metal constituting the windings.A third Coil Doma in fea ture is provided, tha t is not used in this model. The Coil Group Doma in fea ture is identica l to the Single-Turn Coil Doma in, with the importa nt difference tha t a pplying this fea ture to multiple doma ins connects the resulting coils in series.j ωσω2ε–()A ϕ∇μ1–∇A ϕ×()×+J ϕe =J ϕe J e d s ⋅S ∫I =Results and DiscussionThe eddy currents induced in the cylinder are shown in the following figures. The induced currents on the cylinder are of comparable magnitude, due to the choice of the parameter, but the current density in the coil is different. Figure 1 presents the results obtained with a Single-Turn Coil Domain feature. The current density is not uniform and is greater in the inner part of the coil (the region closer to the z axis) and close to the surface (due to the skin effect).Figure 1: Results using a Single-Turn Coil Domain feature.In Figure 2, the Multi-Turn Coil Domain feature is used. While the effect on the cylinder is similar to the one obtained with a Single Turn Coil Domain, the current density in the coil is uniform, according to the coil approximation stated above.Figure 2: Results using a Multi-Turn Coil Domain feature.Model Library path: ACDC_Module/Tutorial_Models/coil_eddy_currentsThe Model Library path shows the location of the Model MPH-file.

ansys推杆模型的建立

ansys推杆模型的建立
在ANSYS中，推杆模型的建立可以通过以下步骤实现：
1. 创建一个新的工程或打开一个现有的工程。

2. 在“Geometry”模块中，选择合适的几何体工具来创建推杆的几何形状。

可以使用基本几何体，如圆柱体或长方体，也可以使用曲线线段和曲线弧段进行自定义建模。

3. 在创建几何形状后，使用“Meshing”模块为推杆设置网格。

选择合适的网格工具和参数，确保网格的精度和适用性。

4. 在“Materials”模块中定义推杆的材料属性。

可以选择预定义
的材料，如金属或塑料，也可以自定义材料属性。

5. 在“Loads”模块中定义施加在推杆上的加载情况。

可以设置力、压力、力矩等加载，并指定施加的位置和方向。

6. 在“Boundary Conditions”模块中定义边界条件。

这包括固定
或约束的点、线或面，并指定其自由度或约束类型。

7. 在“Analysis Settings”模块中选择分析类型、求解器选项和其
他分析参数。

根据需要进行设置。

8. 在“Solution”模块中运行推杆模型进行求解。

根据设置的加
载和边界条件，计算机会进行数值计算，并输出结果。

9. 在“Results”模块中查看和分析推杆模型的结果。

包括位移、
应力、应变等结果数据，还可以生成图表或动画来可视化结果。

10. 根据需要，可以在“Design Exploration”模块中进行参数化
建模和优化。

通过以上步骤，可以在ANSYS中建立推杆模型，并进行相应
的分析和求解，以获得相关结果信息。
