[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] Example 1 This embodiment provides a shock-resistant water cooling device, such as Figure 1 As shown, it includes a frame 1 and a main pump 2, a main pipe 9, a filter 4 and an ion exchanger 5 arranged in the frame 1. The ion exchanger 5 is arranged on one side of the frame 1, and the main pump 2 is connected to the ion exchanger 5. The filter 4 is arranged on the other side of the frame 1, and is connected to the main pump 2 and the ion exchanger 5 respectively.

[0018] In this embodiment, the frame 1 is made of Q235 carbon steel with a thickness of 10 mm. The yield strength of Q235 carbon steel is 235 MPa.

[0019] In order to verify the overload position in the water cooling device, this embodiment performs structural static simulation and response spectrum analysis on the water cooling device.

[0020] Structural static simulation: Fix the bottom surface of the original water cooling device and apply gravity acceleration g = 9.8m / s to the water cooling device 2 The overload locations obtained from the simulation results are shown in Table 1.

[0021] Table 1 Structural static simulation results Location Carbon Steel Model Maximum equivalent stress MPa Between main pump and frame Q235 307 Between filters and frames Q235 299 Between ion exchanger and frame Q235 329 As shown in Table 1, the maximum equivalent stresses between the main pump 2 and the frame 1, between the filter 4 and the frame 1, and between the ion exchanger 5 and the frame 1 are all greater than 235 MPa, which are overloaded parts.

[0022] Response spectrum analysis: The response spectrum method is used for structural seismic analysis. The model is loaded using a standard excitation time-history wave fitted with a standard response spectrum. The seismic load is based on the spectrum "high" RSS 2% damping of ETG1.020-1997. The basic acceleration in the horizontal direction is 0.5g, and the basic acceleration in the vertical direction is 0.3g. The corresponding acceleration at each frequency is obtained according to ETG1.020-1997, and the vertical acceleration is a 0.6 proportional factor of the horizontal acceleration. The earthquake simulation considers the excitation earthquake analysis in two directions at the same time, horizontal A+vertical, horizontal B+vertical. The analysis results are shown in Table 2.

[0023] Table 2 Response spectrum analysis results Location Carbon Steel Model Maximum equivalent stress MPa Between main pump and frame Q235 297 Between filters and frames Q235 277 Between ion exchanger and frame Q235 257 As shown in Table 2, the maximum equivalent stresses between the main pump and the frame, between the filter and the frame, and between the ion exchanger and the frame are all greater than 235 MPa, indicating that they are overloaded locations.

[0024] Through structural static simulation and response spectrum analysis, under the action of seismic loads with a horizontal basic acceleration of 0.5g and a vertical basic acceleration of 0.3g, the areas between the main pump 2 and the frame 1, between the filter 4 and the frame 1, and between the ion exchanger 5 and the frame 1 in the water cooling device are overloaded areas, and structural optimization is required for the above three areas.

[0025] like Figure 1 As shown, in this embodiment, the structural strength is improved by adding a shock absorbing compensator 3, a first expansion joint 8, a first metal hose 7, a shock absorber 6, a second expansion joint 11, and a second metal hose 10.

[0026] Specifically, a shock absorbing compensator 3 is provided on the peripheral side of the bottom of the frame 1. A first expansion joint 8 is provided on the inlet and outlet pipelines of the main pump 2 to reduce the stress concentration of the main pipeline 9 on the support of the main pump. A second expansion joint 11 is provided on the outlet pipeline of the filter 4, and the main pipeline 9 is connected through the second expansion joint 11; a first metal hose 7 is provided on the connecting branch between the second expansion joint 11 and the main pipeline 9. A shock absorber 6 is provided between the ion exchanger 5 and the frame 1 to increase the buffer while ensuring the support strength, and effectively reduce the contact effect of vibration on the ion exchanger 5 and the support of the frame 1. A second metal hose 10 is provided on the connecting branch of the ion exchanger 5 to ensure the variability of the size of the connecting branch on the one hand, and to reduce the influence of vibration on the connecting branch on the other hand.

[0027] Example 2 Based on Example 1, this embodiment provides a configuration method of the shock absorbing compensator 3 , the first expansion joint 8 , the first metal hose 7 , the shock absorber 6 , the second expansion joint 11 , and the second metal hose 10 .

[0028] like Figure 1 and 3 As shown, 4 to 6 damping compensators 3 are arranged around the bottom of the frame 1. In this embodiment, 6 damping compensators 3 are arranged.

[0029] The first metal hose 7 is arranged on the vertical connecting branch of the filter 4, and both ends of the first metal hose 7 are sealed to connect the vertical connecting branch of the filter 4 to ensure the sealing of the connection between the vertical connecting branch and the filter 4. The vertical connecting branch of the filter 4 is connected to the main pipeline 9.

[0030] like Figure 1 and 2 As shown, a shock absorber 6 is provided between the filter 4 and the frame 1 for buffering between the filter 4 and the frame 1 .

[0031] like Figure 1 As shown, the upper connecting branch and the lower connecting branch of the ion exchanger 5 are both provided with a second metal hose 10, which ensures the variability of the size of the upper connecting branch and the lower connecting branch on the one hand, and reduces the impact of vibration on the upper connecting branch and the lower connecting branch on the other hand.
