Technical Field

[0001] This utility model relates to the field of server rack technology, specifically a liquid cooling pipeline device for server racks. Background Technology

[0002] With the rapid development of supercomputer technology, server racks with high heat flux density are widely used in the supercomputer field. Traditional server racks mainly use air-cooled structures for cooling, but this can no longer meet their heat dissipation requirements. As the number of server racks increases and their arrangement becomes more and more dense, the cold air blown out by the cooling air conditioning system cannot circulate sufficiently throughout the computer room, causing hot air to tend to concentrate in specific areas, which can lead to instability in the server rack system. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a liquid cooling pipeline device for server racks. It adopts a liquid-cooled pipeline structure and is installed in various locations within the server rack. The cooling circulating liquid circulates and cools the server rack system through filter pipes, ensuring the stability of the server rack system.

[0004] To achieve the above objectives, a liquid cooling pipeline device for server racks is designed, comprising a pipeline, a ball valve, a flow sensor, a filter, an exhaust valve, and a pipe. The device is characterized in that: one end of the pipeline is connected to one end of a first ball valve, the other end of the ball valve is connected to a flexible hose, the other end of the pipeline is connected to one end of a flow sensor, the other end of the flow sensor is connected to one end of a filter, and the other end of the filter is connected to an exhaust valve and a water outlet pipeline, respectively.

[0005] One end of the hose is connected to the water inlet, and the other end of the hose is connected to one end of the pagoda head nut, which in turn is connected to the first ball valve.

[0006] The two ends of the first ball valve are respectively connected to the pagoda head nut and one end of the first flange nut through washers. The other end of the first flange nut is connected to the pipeline through a sealing ring, and a first clamp is fitted on the first flange nut.

[0007] The flow sensor is connected to one end of the second flange nut at each end, and the other end of the second flange nuts on both sides is connected to the pipe and filter through a sealing ring. A second clamp is fitted on each of the second flange nuts on both sides.

[0008] The filter includes a filter housing and a filter inner liner. The filter housing is equipped with a filter inner liner and has a three-way structure. One end is connected to a flow sensor, another end is connected to an air vent valve, and the third end is connected to one end of a second ball valve. The other end of the second ball valve is connected to the outlet pipe.

[0009] The exhaust valve is connected to the other end of the filter via a gasket, and a third clamp is fitted onto the other end of the filter.

[0010] The two ends of the second ball valve are respectively connected to one end of the third flange nut through washers, and the other ends of the third flange nuts on both sides are connected to one end of the third port and outlet pipe of the filter through sealing rings. A fourth clamp is respectively fitted on the third flange nuts on both sides.

[0011] The sealing ring is an O-ring.

[0012] The gasket is a stainless steel + EPDM gasket.

[0013] Compared with the prior art, this utility model provides a liquid cooling pipeline device for server racks. It adopts a liquid cooling pipeline structure and is installed in various locations in the server rack. The cooling circulating liquid is circulated and cooled through filter pipelines to ensure the stability of the server rack system. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5As shown, one end of pipe 3 is connected to one end of the first ball valve 2, the other end of ball valve 2 is connected to hose 1, the other end of pipe 3 is connected to one end of flow sensor 4, the other end of flow sensor 4 is connected to one end of filter 5, and the other end of filter 5 is connected to air vent valve 6 and outlet pipe 7 respectively.

[0023] One end of the hose 1 is connected to the water inlet, and the other end of the hose 1 is connected to one end of the pagoda head nut 8. The other end of the pagoda head nut 8 is connected to the first ball valve 2.

[0024] The two ends of the first ball valve 2 are connected to the pagoda head nut 8 and one end of the first flange nut 9 respectively through washers. The other end of the first flange nut 9 is connected to the pipe 3 through a sealing ring, and a first clamp 10 is fitted on the first flange nut 9.

[0025] The two ends of the flow sensor 4 are respectively connected to one end of the second flange nut 11, and the other ends of the second flange nuts 11 on both sides are connected to the pipe 3 and the filter 5 through the sealing ring. The second flange nuts 11 on both sides are respectively fitted with second clamps 12.

[0026] The filter 5 includes a filter housing and a filter inner liner. The filter housing 5-1 contains a filter inner liner 5-2. The filter housing 5-1 has a three-way structure. One end is connected to the flow sensor 4, another end is connected to the air vent valve 6, and the third end is connected to one end of the second ball valve 13. The other end of the second ball valve 13 is connected to the outlet pipe 7.

[0027] Filter housing 5-1: The material is SUS304L or SUS316L, and the surface must be free of burrs and sharp edges. The inlet and outlet fluid ends of the filter housing 5-1 are both standard flange structures, which facilitates the connection of various pipelines.

[0028] Filter liner 5-2: The material is SUS304L or SUS316L, and the round holes on the surface are fluid channels; the inside of filter liner 5-2 needs to be filled with a 500-mesh SUS304 mesh, which is welded inside the filter liner 5-2; when the fluid passes through the 500-mesh stainless steel mesh, the particles in the fluid are filtered out, ensuring that the particles in the pipeline are less than 150um; the cooling fluid enters the filter 5 from the inlet direction of the hose 1, and the fluid pressure in the pipeline will pass through the filter liner 5-2 and the wire mesh with the fluid, and enter the equipment pipeline after filtration.

[0029] The exhaust valve 6 is connected to the other end of the filter 5 via a gasket, and a third clamp 14 is fitted onto the other end of the filter 5.

[0030] The two ends of the second ball valve 13 are connected to one end of the third flange nut 15 through gaskets. The other ends of the third flange nuts 15 on both sides are connected to one end of the third passage and outlet pipe 7 of the filter 5 through sealing rings. The third flange nuts 15 on both sides are respectively fitted with fourth clamps 16.

[0031] The sealing ring is an O-ring.

[0032] The gasket is made of stainless steel and EPDM.

[0033] Applications of this invention: Cooling circulating liquid passes through filter pipes and is used in server racks and various liquid cooling mechanisms.

[0034] The working principle of this utility model is as follows: Liquid enters through the inlet of hose 1, passes through the first ball valve 2, pipe 3, flow sensor 4 (i.e., flow meter), and the second ball valve 13 on filter 5, and then flows through outlet pipe 7 to the remaining pipes, such as... Figure 6 As shown.

[0035] Among them, the first ball valve 2 and the second ball valve 13 control the pressure values ​​on both sides. When the pressure values ​​on both sides exceed the set range, the valve will automatically control the switch and adjust the pressure values ​​on both sides to a certain range, so as to maintain a certain flow rate and pressure of cooling liquid in the pipeline.

[0036] The use of clamps facilitates the connection of various complex pipelines. The pipelines on both sides are sealed with standard flanges, and the middle is sealed with a sealing ring (i.e., an O-ring) to prevent liquid from leaking at the pipeline connection.

[0037] Particulate matter in the cooling liquid is filtered by filter 5 to keep the particulate matter in the cooling liquid below 150um, preventing impurities from clogging the outlet and damaging various valves.

[0038] The exhaust valve 6 performs the function of eliminating air buildup in the control system without any manual intervention.

[0039] All pipe connections require sealing gaskets (i.e., stainless steel + EPDM gaskets), and different gaskets and connecting nuts are used depending on the connection method.
