DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 4 The centralized cooling device for a data center computer room shown in the figure comprises a plurality of chassis 1 installed in the data center computer room, spray pipes 2 and recovery pipes 3 are respectively installed on the outer sides of the plurality of chassis 1, and cooling oil circulates in the spray pipes 2 and the recovery pipes 3, and is characterized in that it also comprises: a coarse filter component for coarsely filtering the cooling oil inside the chassis 1, a cleaning component for cleaning impurities inside the coarse filter component, and a driving component;

[0027] One end of the recovery pipe 3 away from the chassis 1 is fixedly connected to a suction pump 4, and the suction pump 4 is used to extract the cooling oil inside the chassis 1 through the recovery pipe 3. The coarse filter assembly includes a guide box 5, and the liquid outlet pipe of the suction pump 4 passes through the guide box 5. An inclined guide plate 6 is fixedly installed inside the guide box 5, and a plurality of baffles 7 distributed at equal distances are installed on the inclined guide plate 6. The cooling oil extracted by the suction pump 4 can flow on the inclined guide plate 6. The lower end of the baffle 7 is fixedly connected to a support plate 8, and the lower end of the inclined guide plate 6 is fixedly installed with a plurality of pins 9 distributed in an array, and a spring 11 is movably sleeved on the outer side of the pin 9. The inclined guide plate 6 is provided with a plurality of plug-in slots 12 equal to the number of baffles 7.

[0028] The inclined guide plate 6 is located at the lower side of the liquid outlet pipe of the suction pump 4, the support plate 8 is located at the lower side of the inclined guide plate 6, the pin rod 9 passes through the support plate 8, the lower end of the pin rod 9 is fixedly connected with a gasket 10, the two ends of the spring 11 are respectively movably abutted against the support plate 8 and the gasket 10, the spring 11 can drive the support plate 8 and the baffle 7 to move upward through the gasket 10, and the baffle 7 is plugged and unplugged with the inclined guide plate 6 through the plug-in slot 12.

[0029] Working principle: During the operation of the chassis 1, the pump body in the cooling oil storage box pumps the cooling oil to the inside of multiple chassis 1 through the spray pipe 2. The spray pipe 2 sprays the cooling oil to the circuit board inside the chassis 1, which can assist the heat dissipation of the circuit board inside the chassis 1. The cooling oil after heat exchange with the circuit board will be sucked into the guide box 5 by the suction pump 4. The cooling oil after coarse filtration in the guide box 5 enters the oil filter 35 for fine filtration, which can effectively prevent the impurities carried in the cooling oil from causing wear and corrosion to the circuit board. After that, the cooling oil after fine filtration in the oil filter 35 flows back to the storage box through the pipeline for cooling.

[0030] After the cooling oil is pumped out from the inside of the chassis 1 by the suction pump 4, it will flow on the inclined guide plate 6. Since a plurality of protruding baffles 7 are installed on the inclined guide plate 6, some of the impurities carried by the cooling oil will be blocked by the baffles 7 and accumulated on the left side of the baffle 7 during the flow. The cooling oil after coarse filtration by the inclined guide plate 6 flows to the bottom of the guide box 5, and then enters the oil filter 35 through the conduit 2 34 for fine filtration, thereby effectively reducing the burden of the oil filter 35, accelerating the flow speed of the cooling oil, and improving the cooling effect of the cooling oil on the circuit boards in the chassis 1.

[0031] Example 2: Please refer to Figure 4-Figure 7, this embodiment further illustrates the first embodiment, the cleaning assembly includes a scraper 13, the cleaning assembly is adapted to be installed obliquely on the inclined guide plate 6, two threaded rods 14 are installed on the scraper 13, one end of one threaded rod 14 is fixedly connected to a drive motor 15, the drive motor 15 is fixed to the guide box 5, the outer side of the inclined guide plate 6 is movably fitted with two symmetrically distributed movable plates 16, the outer side of the inclined guide plate 6 is fixedly installed with a plurality of pin blocks 17 corresponding to the movable plate 16, and the lower end of the movable plate 16 is fixedly installed with a plurality of baffles 7 in number. Equal triangular push blocks 19, a connecting rod 20 is fixedly embedded at the left end of the movable plate 16, a stopper 21 is movably sleeved on the outer side of the connecting rod 20, a spring 22 is also movably sleeved on the outer side of the connecting rod 20, a connecting rod 23 is fixedly installed between the two connecting rods 20, a movable groove 24 is opened on the inclined guide plate 6 corresponding to the connecting rod 23, and the connecting rod 23 is slidably connected to the inclined guide plate 6 through the movable groove 24, the connection between the scraper 13 and the connecting rod 23 is a movable abutment, and cylindrical stop rods 25 are fixedly embedded at both ends of the support plate 8;

[0032] The lower end of the scraper 13 is movably fitted with the upper end surface of the inclined guide plate 6, and the two threaded rods 14 are linked by a synchronous wheel and a synchronous belt. The threaded rod 14 is rotatably connected to the guide box 5 through a bearing. The driving motor 15 is located on the outside of the guide box 5. A limited straight groove 18 is provided on the side of the movable plate 16 close to the inclined guide plate 6. The movable plate 16 is slidably connected with the pin block 17 through the limited straight groove 18. The pin block 17 is located in the limited straight groove 18 to prevent the movable plate 16 from detaching from the inclined guide plate 6. The hypotenuse of the triangular push block 19 is located on the right side. The connection between the block 21 and the inclined guide plate 6 is a fixed connection. The two ends of the spring 22 are movably abutted against the movable plate 16 and the block 21 respectively. The block 21 is used to position the end of the spring 22 away from the movable plate 16. The connecting rod 23 is close to the end of the connecting rod 1 20 away from the movable plate 16, and the connection between the cylindrical block rod 25 and the triangular push block 19 is a movably abutted.

[0033] In this embodiment: when the impurities coarsely filtered out by the baffle 7 are cleaned regularly, the driving motor 15 runs to drive the threaded rod 14 to rotate, and the threaded rod 14 rotates to drive the scraper 13 to move to the lower right. At this time, the movable plate 16 and the plurality of triangular push blocks 19 will move to the lower right under the drive of the compression elastic force of the spring 22. During the movement, the triangular push block 19 drives the cylindrical baffle rod 25 and the baffle 7 to move downward through its bevel edge, so that the upper end surface of the baffle 7 is flush with the upper end surface of the inclined guide plate 6. In the process that the scraper 13 continues to move in contact with the inclined guide plate 6, the oil containing impurities on the inclined guide plate 6 on the scraper 13 is scraped off, and the inclined guide plate 6 can be cleaned regularly to avoid the accumulation of impurities on the left side of the baffle 7, which causes the coarse filtering component to lose the coarse filtering effect on the oil.

[0034] When the threaded rod 14 rotates in the opposite direction to drive the scraper 13 to move back and reset, the scraper 13 will resist the connecting rod 23, and drive the movable plate 16 and multiple triangular push blocks 19 to move back and reset through the connecting rod 23. During this process, multiple baffles 7 will move up and reset under the compression force of multiple springs 11.

[0036] A plurality of drain pipes 31 equidistantly distributed are fixedly installed at the bottom of the guide box 5, and the plurality of drain pipes 31 are located on the right side of the airbag strip 30. A solenoid valve 32 is fixedly installed on the outer side of the drain pipe 31. The lower end of the drain pipe 31 is connected to a drain pump 33 through a pipeline. The drain pump 33 is used to discharge cooling oil containing impurities. A second conduit 34 is also fixedly installed at the bottom of the guide box 5, and the second conduit 34 is located on the left side of the airbag strip 30. The end of the second conduit 34 away from the guide box 5 is connected to an oil filter 35.

[0037] In this embodiment: before the scraper 13 cleans the inclined guide plate 6, a small amount of cooling oil is stored at the bottom of the guide box 5. When the scraper 13 moves to clean the inclined guide plate 6 and the movable plate 16 moves to the lower right to drive the baffle 7 to move downward, the movable plate 16 drives the piston 27 to move inside the sleeve 28 through the push rod 26, and the gas inside the sleeve 28 is squeezed into the air bag strip 30. The air bag strip 30 is inflated to increase its height, and the inner bottom of the guide box 5 is divided into two areas. It can effectively prevent the oil containing a large amount of impurities scraped off by the scraper 13 from polluting the guide box 5 over a large area.
