Description

Technical Field

[0001] This application relates to the technical field of energy storage liquid cooling heat dissipation, and more specifically, to a multi-pipeline connection and support structure. Background Art

[0002] Energy storage liquid cooling heat dissipation technology (CDU technology) is an advanced thermal management technology, mainly used for efficient heat dissipation of high-density heat-generating devices such as data centers and servers. The background and development of this technology are based on the continuous pursuit of energy efficiency, stability, and reliability of data centers, as well as the emphasis on environmental protection and sustainability. With the expansion of the application scale of data centers and servers, traditional air cooling technology can no longer meet the growing heat dissipation requirements. Therefore, liquid cooling technology has emerged as an effective means to solve the heat dissipation problem of high-density heat-generating devices. Liquid cooling CDU (Cooling Distribution Unit) is a key component in liquid cooling technology. It transports the cooling medium to the devices that need to be cooled, such as IT heat-generating devices like servers and memories, through a series of pipes and pumps. Compared with traditional air cooling methods, this technology can transfer heat from computing devices to the cooling medium more directly and efficiently, thereby improving the energy utilization rate of data centers, reducing power costs, and reducing the risk of hardware failures caused by high temperatures. Generally speaking, energy storage liquid cooling CDU is based on the need to solve the heat dissipation problem of high-density heat-generating devices in data centers, as well as the improvement of energy efficiency, equipment stability, reliability, and environmental protection requirements. The development and application of this technology are of great significance for improving the energy utilization rate of data centers, reducing operating costs, and enhancing equipment stability and reliability.

[0003] In the existing energy storage liquid cooling heat dissipation technology (energy storage cooling system), multiple pump bodies pump liquid through pipes respectively, and the pumped liquid is merged into the main pipeline for transportation. To prevent the liquid in each pump body pipeline from flowing back, a check valve needs to be connected to the output end of each pump body through a pipe. Usually, the check valve is suspended by connecting it to the pipe. If the connecting pipes are set at a long distance, it will cause the check valve to easily bend the pipe, resulting in pipe deformation and easy leakage problems.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0042] Such as Figure 2As shown in the figure, this embodiment proposes a multi-pipeline connection and support structure, which can be applied to multiple water circuits in an energy storage liquid cooling system. Each water circuit includes a water inlet part 10 and a water outlet part 20. The water inlet part 10 and the water outlet part 20 are connected through this multi-pipeline connection and support structure, so as to provide support for the pipelines in the energy storage liquid cooling system, thereby realizing the technical solution of the energy storage liquid cooling CDU.

[0043] As Figure 1 , Figure 3 shown in the figure, a multi-pipeline connection and support structure of this embodiment mainly includes: a support seat body 100, a plurality of connecting pipelines 110, and a plurality of filter elements 120. Usually, a base is provided in the energy storage liquid cooling system to provide installation positions for various components in the entire liquid cooling system. The support seat body 100 is fixedly arranged on the base, and a plurality of connecting pipelines 110 are all arranged on the support seat body 100. A plurality of water circuits are arranged in one-to-one correspondence with the connecting pipelines and are connected and communicated, so that the support seat body 100 fixedly supports the water circuits and enables the water circuits to form a stable layout. A plurality of filter elements 120 are respectively arranged in a plurality of connecting pipelines 110, and one filter element 120 is arranged in each connecting pipeline. When the liquid cooling water flow passes through the connecting pipeline, it is filtered by the filter element 120, so as to filter out the impurities in the liquid cooling water.

[0044] As Figure 1 , Figure 2 , Figure 3 shown in the figure, each connecting pipeline of this embodiment includes: a water passing hole 111, a water inlet branch pipe 113, and a water outlet branch pipe 117. The water passing hole 111 can be opened in the support seat body 100 along the vertical direction, and the water inlet branch pipe 113 and the water outlet branch pipe 117 can be arranged along the horizontal direction. Among them, the water inlet branch pipe 113 is arranged on one side surface of the support seat body 100, so as to protrude from the side surface of the support seat body 100, and its interior is connected and communicated with the water passing hole 111. The protruding water inlet branch pipe 113 is convenient for detachable connection with the water inlet part 10. The water outlet branch pipe 117 is arranged on the other side surface of the support seat body 100, and is arranged opposite to the water inlet branch pipe 113. Its interior is connected and communicated with the water passing hole 111. The water inlet branch pipe 113 protruding towards the other side is convenient for detachable connection with the water outlet part 20. The liquid cooling water flow in the water inlet part 10 passes through the water inlet branch pipe 113, is filtered by the filter element 120 in the water passing hole 111, and the filtered liquid cooling water flows into the water outlet branch pipe 117, and then smoothly flows into the water outlet part 20.

[0045] As Figure 2 , Figure 3As shown, when a multi-pipeline connection support structure provided by the present application is used for multiple waterway settings, this connection support structure is arranged between the water inlet member 10 and the water outlet member 20 in each waterway, and is stably supported by the fixedly arranged support seat body 100. The multiple connecting pipelines 110 on the support seat body 100 are connected to each waterway in a one-to-one correspondence, thus ensuring the smoothness of the waterways. Therefore, during the connection process, through the fixed support of the support seat body 100, multiple waterways can be lifted, and the middle of multiple waterway pipes can also be stably supported. Even when the distance between the water inlet member 10 and the water outlet member 20 is relatively far, or when the water outlet member 20 needs to be carried by the pipeline, the load-bearing structure strength of the waterway pipes can be enhanced, and the problem of leakage caused by the deformation of the pipeline due to the bending of the pipeline can be avoided. Moreover, a filter member 120 is arranged in the connecting pipeline to filter out impurities in each waterway, ensure the cleanliness of the coolant in the waterway, and reduce the risk of blockage of the waterway.

[0046] As Figure 1 、 Figure 2 shown, further, the support seat body 100 of this embodiment is square, the support seat body 100 is arranged along the vertical direction, and has a length direction and a width direction in the horizontal direction, wherein the direction where the long side is located in the horizontal plane is the length direction, and the direction where the short side is located is the width direction. The support seat body 100 is arranged along the up-down direction. To increase the height of the support seat body 100, so that the heights of the water inlet branch pipe 113 and the water outlet branch pipe 117 are also correspondingly increased, so that the water inlet member 10 and the water outlet member 20 can be lifted. A lifting bracket 140 is connected to the bottom of the support seat body 100 by screws, and the lifting bracket 140 can be in a U-shape. The support seat body 100 is stably fixed on the base through the U-shaped lifting bracket 140. And the support seat body 100 arranged along the vertical direction matches the preset height of the waterway, so as to realize the stable support of the waterway.

[0047] The multiple connecting pipelines 110 in this embodiment are arranged at intervals in the length direction, so that each connecting pipeline does not interfere, and each waterway connected by each connecting pipeline can be stably supported. The water inlet branch pipe 113 and the water outlet branch pipe 117 protrude outwards on both sides in the width direction, which is convenient for the detachable connection of the pipelines. Only arranged in the length direction, the volume of the support seat body 100 is reduced and optimized.

[0048] As Figure 1 、 Figure 2 shown, further, the heights of the water outlet branch pipe 117 and / or the water inlet branch pipe 113 in the multiple connecting pipelines 110 of this embodiment are different in the vertical direction. In the specific structure, the heights of the water inlet branch pipes 113 can be the same, but the water outlet branch pipes 117 usually need to be connected to various valve-type water outlet members 20 (such as one-way valves). An offset form with different heights is adopted to provide an installation position for the valve-type water outlet members 20.

[0049] As Figure 3 、 Figure 4 shown, further, the filter element 120 of this embodiment can be arranged in the water passing hole 111. Specifically, the filter element 120 includes a filter bracket 121 and a mesh layer 126. The filter bracket 121 is arranged in the water passing hole 111, so that the support seat body 100 can provide sufficient support positions. The mesh layer 126 is arranged on the filter bracket 121 and fills the cross section of the water passing hole 111. By inserting the filter bracket 121 into the water passing hole 111, the mesh layer 126 can cover the entire water passing hole 111. The liquid cooling water is filtered through the mesh layer 126 in the water passing hole 111, so as to intercept the impurities in the liquid cooling water and keep the liquid cooling water clean.

[0050] As Figure 3 、 Figure 4 shown, further, the water passing hole 111 of this embodiment is arranged on the support seat body 100 in the vertical direction and forms an opening at the top of the support seat body 100. An internal thread is arranged in the opening to form a threaded hole 112. A sealing cover 150 is screwed to the threaded hole 112. The sealing cover 150 is used to seal the opening of the water passing hole 111. The filter element 120 is inserted into the water passing hole 111 from the opening from top to bottom, and then the sealing cover 150 is tightened in cooperation with the threaded hole 112, so as to facilitate the installation and disassembly of the filter element 120, and thus the filter element 120 can be conveniently taken out to clean the filter residue.

[0051] As Figure 3 、 Figure 4 shown, further, the threaded hole 112 of the water passing hole 111 of this embodiment is set as a threaded counterbore, and the threaded counterbore is used to cooperate with and limit the filter bracket 121, so that the filter element 120 can be stably embedded in the water passing hole 111. The filter bracket 121 of this embodiment includes a retaining ring 122, connecting side plates 123 and a filter cover 124. The connecting side plates 123 are fixedly connected below the retaining ring 122, and the filter cover 124 is connected below the connecting side plates 123. The retaining ring 122 is arranged in the threaded counterbore, and the bottom surface of the threaded counterbore supports the retaining ring 122 to limit the retaining ring 122 in the threaded counterbore. There are multiple connecting side plates 123, for example, 2. The multiple connecting side plates 123 are circumferentially spaced around the retaining ring 122, and the outer diameter of the circle surrounded is smaller than the outer diameter of the retaining ring 122. The multiple connecting side plates 123 all extend in the vertical direction, and an inlet is formed between adjacent connecting side plates 123. The inlet is opposite to the orifice of the water inlet branch pipe 113, so that the liquid cooling water can smoothly flow into the filter element 120. The filter cover 124 is connected to the connecting side plates 123, and the mesh layer 126 is arranged on the filter cover 124. The mesh layer 126 is fixed circumferentially through the filter cover 124, so that the mesh layer 126 can be stably filled in the water passing hole 111.

[0052] AsFigure 3 , Figure 4 As shown in Figure 4 , further, the lower end of the filter cover 124 of this embodiment forms an arc-shaped inner wall, and an outlet 125 is provided on the side wall of the arc-shaped inner wall. The outlet 125 is communicated with the water outlet branch pipe 117. The filter cover 124 is set to be arc-shaped to guide the water flow impacting from top to bottom, so that the water flow is buffered at the corner, avoiding excessive impact and resulting in large resistance of the liquid cooling water flow, thus greatly affecting the fluidity of the liquid cooling water.

[0053] To make the outlet 125 face the water outlet branch pipe 117 directly, an anti-fooling groove (not marked in the figure) is provided on the side wall of the threaded counterbore, and correspondingly, an anti-fooling boss is protruded at the corresponding position on the outer wall of the retaining ring 122. When the filter element 120 is installed into the water passing hole 111, the anti-fooling boss can be inserted into the anti-fooling groove, so that the position of the retaining ring 122 in the threaded counterbore is limited and cannot rotate. At this position, the outlet 125 of the lower filter cover 124 faces the water outlet branch pipe 117 directly, thus facilitating accurate alignment during installation.

[0054] As Figure 3 , Figure 4 shown in Figure 4 , in another solution, a connection port 114 is formed at the connection between the inner wall of the water inlet branch pipe 113 and the water passing hole 111. The mesh layer 126 is located below the connection port 114, and a flow disturbance structure 130 is provided on the inner wall of the connection port 114. The flow disturbance structure 130 is used to change the direction of the water flow in the water inlet branch pipe 113 to impact the filter element 120. The flow disturbance structure 130 can be a flow disturbance column or a flow disturbance block, etc. By the flow disturbance structure 130, the water flow direction at the connection port 114 can be changed, which can not only reduce the amount of liquid cooling water flow entering the water passing hole 111 and vertically impacting the inside of the water passing hole 111. Moreover, through the flow disturbance effect, the formation of vortices often accompanies, so vortices can be generated to cause the change of the fluid velocity direction, making the fluid rotate in a certain direction, thus generating a certain impact on the impurities deposited on the mesh layer 126. Especially due to the rotational nature of the vortices, it will cause the fluid flow rate to pulsate, that is, the fluid flow rate will continuously increase and decrease, so that the impurities deposited on the mesh layer 126 can be rolled up, avoiding the deposition of impurities on the mesh layer 126 during the process of water flow entering the filter element 120, resulting in water flow obstruction or even blockage.

[0055] As Figure 3 , Figure 5 , Figure 6As shown, further, the spoiler structure 130 of this embodiment specifically includes a plurality of inclined guide vanes 131, and the plurality of inclined guide vanes 131 are circumferentially spaced on the inner wall of the water inlet branch pipe 113. By circumferentially spacing the inclined guide vanes 131 at the connection port 114, the inclined guide vanes 131 extend obliquely along the width direction. By guiding the water flow through the inclined guide vanes 131, the direction of the water flow can be guided to change obliquely in a certain direction, which is more conducive to forming a vortex, so that the impurities deposited on the mesh layer 126 are impacted and rolled up. In the specific structure of the inclined guide vane 131, with the central axis 115 of the water inlet branch pipe 113 as a reference, the projection of the inclined guide vane 131 in the horizontal direction is inclined to the central axis 115 of the water inlet branch pipe 113. Thus, the water flow in the connection port 114 gradually changes direction.

[0056] As Figure 5 , Figure 6 shown, the contour of the inclined guide vane 131 in the cross-section of the water inlet branch pipe 113 is arc-shaped. By using the inclined guide vane 131 with an arc-shaped contour, the liquid cooling water flows along the arc-shaped contour, thereby guiding the direction of the liquid cooling water flow and enabling the liquid cooling water flow to smoothly enter above the mesh layer 126. In addition, since the inclined guide vane 131 will cause the water flow to be blocked, guiding the water flow through the arc-shaped contour can minimize the loss of water flow energy.

[0057] As Figure 3 , Figure 4 shown, in other solutions, the diameter of the connection port 114 gradually decreases along the direction of the central axis of the water inlet branch pipe 113 towards the water passing hole 111. Along the direction of the liquid cooling water flow, the aperture of the connection port 114 gradually becomes smaller, so that the liquid cooling water flow is pressured and guided into the water passing hole 111. This is equivalent to increasing the impact force of the liquid cooling water flow through a small aperture. The liquid cooling water flow with a larger impact force is more likely to wash up the impurities deposited on the mesh layer 126, which is more conducive to ensuring smooth water passage through the mesh layer 126.

[0058] As Figure 3 shown, further, a leak-proof boss 116 is provided at the end of the water inlet branch pipe 113 of this embodiment. The water inlet member 10 is sleeved on the water inlet branch pipe 113 by squeezing the leak-proof boss 116, and the water inlet member 10 is fixed on the water inlet branch pipe 113 by a clamp. As Figure 1 , Figure 2 shown, a docking flange 118 is provided at the end of the water outlet branch pipe 117. The water outlet member 20 is externally aligned and connected with the docking flange 118 and fixed on the water outlet branch pipe 117 by a quick-release snap ring 119.

[0059] In summary, a multi-pipeline connection support structure provided by the present application is fixedly supported by a support seat body, and stable support is also provided in the middle of multiple pipelines. Even when the distance between the water inlet part and the water outlet part is relatively far, or when the water outlet part needs to be supported by a pipeline, the load-bearing structure strength of the water pipeline can be enhanced, and the problem of leakage caused by pipeline deformation due to bending of the pipeline can be avoided. Moreover, a filter element is arranged in the connecting pipeline, which can filter out impurities in each waterway, ensure the cleanliness of the coolant in the waterway, and reduce the risk of blockage of the waterway.

[0060] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
