DETAILED DESCRIPTION

[0020] In the submerged server, the electronic components in the server are usually completely immersed by the cooling liquid, the cooling liquid circulates between the server and the external radiator, the electronic components inside the server are cooled when the cooling liquid is in the server, the heat is absorbed by the cooling liquid, the cooling liquid is pumped out to the radiator by the pump body, the cooling liquid is cooled by the radiator, and the cooled cooling liquid is pumped into the server by the pipeline to cool the electronic components, forming an internal and external circulation type heat dissipation system.

[0021] The utility model provides a kind of flow safety control device for submerged server as Figures 1-4 The flow safety control device considers that the cooling liquid is usually installed between different specifications of servers, the pipeline length for transmitting cooling liquid is different, especially in the bending angle of pipeline, liquid microvibration phenomenon is easy to form, when liquid microvibration phenomenon appears, it usually causes that the pressure in pipeline is too high, and the cooling liquid is easy to gasify when the pressure in pipeline is too high.

[0022] For example, when mineral oil is used as cooling liquid, gas bubbles are formed by vaporization of mineral oil, and these gas bubbles will break under high pressure environment, causing cavitation phenomenon. Specifically, when mineral oil flows in the hydraulic system, due to pressure change, air dissolved in oil will separate out to form gas bubbles. When these gas bubbles move with oil to high pressure area, the volume of gas bubbles is sharply reduced under pressure until it collapses, causing cavitation phenomenon. High instantaneous pressure and high temperature will be accompanied in the process of cavitation, which will cause damage to the hydraulic system and components; And it is easy to produce larger noise and vibration, frequent cavitation will cause rapid wear of electronic components, increase maintenance cost and downtime.

[0023] Reference Figure 1As shown in the utility model, the elastic bend pipe 200 is in an arc pipeline state, both ends of the elastic bend pipe 200 are fixedly provided with flange connecting discs 201, the flange connecting disc 201 is used for being connected with the flange connecting disc 201 at the end of the cooling liquid transmission main pipe 100, the purpose that the cooling liquid transmission main pipe 100 is connected with the flange connecting disc 201 is achieved, the flange connecting disc 201 is usually connected at the corner of the cooling liquid transmission main pipe 100, the elastic bend pipe 200 can be made of materials such as silicon rubber that have elastic deformation capacity, but it needs to be noted that it can be used after anticorrosion treatment, since the elastic bend pipe 200 can elastically deform to a certain extent, when the cooling liquid is reversed through the elastic bend pipe 200, the impact force can impact the elastic deformation of the elastic bend pipe 200, the purpose of buffering and unloading is achieved, the liquid microvibration phenomenon generated when the cooling liquid passes through the corner of the pipeline is reduced, thereby the internal pressure of the pipeline is reduced to a certain extent, and the phenomenon that a series of problems are caused by the gasification of the cooling liquid is avoided.

[0024] Reference Figure 1 And Figure 2 As shown in the utility model, the elastic bend pipe 200 is in an arc pipeline state, both ends of the elastic bend pipe 200 are fixedly provided with flange connecting discs 201, the flange connecting disc 201 is used for being connected with the flange connecting disc 201 at the end of the cooling liquid transmission main pipe 100, the purpose that the cooling liquid transmission main pipe 100 is connected with the flange connecting disc 201 is achieved, the flange connecting disc 201 is usually connected at the corner of the cooling liquid transmission main pipe 100, the elastic bend pipe 200 can be made of materials such as silicon rubber that have elastic deformation capacity, but it needs to be noted that it can be used after anticorrosion treatment, since the elastic bend pipe 200 can elastically deform to a certain extent, when the cooling liquid is reversed through the elastic bend pipe 200, the impact force can impact the elastic deformation of the elastic bend pipe 200, the purpose of buffering and unloading is achieved, the liquid microvibration phenomenon generated when the cooling liquid passes through the corner of the pipeline is reduced, thereby the internal pressure of the pipeline is reduced to a certain extent, and the phenomenon that a series of problems are caused by the gasification of the cooling liquid is avoided.

[0025] It should be noted that in the shell 202, the spring 203 and the pressing plate 204 are provided with a plurality of equidistant distribution, which will not be repeated here.

[0026] Furthermore, an air inlet 207 and an air outlet 206 are provided on the outer casing 202. Both the air inlet 207 and the air outlet 206 connect the inside and outside of the outer casing 202. The diameter of the air outlet 206 is larger than the diameter of the air inlet 207. A one-way valve is provided in the air outlet 206 to allow gas inside the outer casing 202 to be discharged to the outside of the outer casing 202 in one direction. When the inner wall of the elastic bend 200 is impacted by coolant, the wall of the elastic bend 200 expands and deforms outward, thereby pushing the gas inside the outer casing 202 to be quickly discharged from the air outlet 206. During the process of the elastic bend 200 returning to its original position, due to the external gas... When replenishing the interior of the outer casing 202, it can only enter through the small-diameter air inlet 207. The gas inside the outer casing 202 will be in a slow pressurization process. Since the pressure inside the elastic bend 200 is higher than the pressure outside the elastic bend 200, the elastic bend 200 will be in a relatively slow reset process after expansion and deformation. When the elastic bend 200 resets slowly, it is less likely to cause secondary agitation of the coolant, thus reducing the backflow phenomenon caused by the rapid deformation and reset of the elastic bend 200 impacting the coolant; further suppressing the phenomenon of liquid micro-oscillation of coolant in the elastic bend 200.

[0027] A pressure sensor 205 is also installed on the inner wall of the flexible bend 200. The pressure sensor 205 can monitor the pressure of the coolant inside the flexible bend 200. The pressure sensor 205 is connected to an external electrical box. The pressure data monitored by the pressure sensor 205 can be transmitted to a remote computer through a wireless transmission module, so that people can monitor whether the coolant pressure is abnormal in real time and maintain it in time.

[0028] refer to Figure 3 and Figure 4 As shown, after the flexible bend 200 is connected to the coolant transmission main pipe 100, a connecting pipe 102 is also installed between the two sections of the coolant transmission main pipe 100. The connecting pipe 102 is distributed on one side of the flexible bend 200. A first solenoid valve 103 is provided on the connecting pipe 102. When the pressure sensor 205 detects that the coolant pressure inside the flexible bend 200 increases, the first solenoid valve 103 can be opened, so that the connecting pipe 102 is also connected. The coolant in the coolant transmission main pipe 100 can flow into the connecting pipe 102 and the flexible bend 200 at the same time. The pressure of the coolant at the bend is appropriately reduced by temporarily increasing the number of pipes at the bend.

[0029] Meanwhile, when the flexible bend 200 is damaged and needs to be replaced separately, the first solenoid valve 103 can be opened to allow coolant to temporarily flow through the connecting pipe 102 without stopping the machine.

[0030] It needs to be explained that the cooling liquid transmission auxiliary pipe 101 is integrally arranged at the end of the cooling liquid transmission main pipe 100, and the end of the cooling liquid transmission auxiliary pipe 101 and the end of the connecting pipe 102 are connected through the flange connecting disc 201, the connection is sealed, and the inside of the cooling liquid transmission main pipe 100 is also provided with a second electromagnetic valve, which controls the on-off of the connection between the cooling liquid transmission main pipe 100 and the elastic bend pipe 200, when the elastic bend pipe 200 is replaced, the second electromagnetic valve is closed, and the elastic bend pipe 200 can be replaced without stopping.

[0031] Among them, the second electromagnetic valve is not shown in the figure, and will not be described here.

[0032] As an extension, the cooling liquid transmission main pipe 100, the elastic bend pipe 200 and the connecting pipe 102 in the utility model can be arranged in the foundation pit excavated on the ground, the surface of the foundation pit is paved with a water leakage grid, the inner wall of the foundation pit can be coated with concrete, forming a concealed arrangement, without occupying ground space, and more beautiful, water can be added in the foundation pit, or rainwater is easily collected in the foundation pit under the action of rainwater for a long time, and the rainwater also cools the cooling liquid in the cooling liquid transmission main pipe 100 to a certain extent, thereby reducing energy consumption and fully utilizing natural resources.

[0033] It needs to be explained that the foundation pit and the water leakage grid are not shown in the figure, which is a technology known to those skilled in the art; the outer wall of the pipe needs to be treated to prevent corrosion.
