[0022] In the following description, if it is indicated to refer to a specific figure or as shown in a specific figure, it is only used to emphasize that most of the related contents described in the subsequent description appear in the specific figure, but it does not limit the subsequent description to only refer to the specific figure.

[0024] The liquid-cooled server system 100 of the present invention comprises: a closed chamber 1, a plurality of liquid-cooled devices 2, a control device 3, a transfer device 4, and a pick-and-place device 5. In the figure of this embodiment, it is taken as an example that four liquid-cooled devices 2, a transfer device 4, and a pick-and-place device 5 are arranged in the closed chamber 1, but the number of liquid-cooled devices 2, transfer devices 4, and pick-and-place devices 5 arranged in the closed chamber 1 is not limited to that shown in the figure.

[0025] The closed chamber 1 may include a pick-up and placement opening 11, a pick-up and placement door 12, and a pick-up and placement platform 13. When the pick-up and placement door 12 is opened, the interior of the closed chamber 1 can be connected to the outside through the pick-up and placement opening 11, and the pick-up and placement platform 13 can place at least one server 200. A portion of the pick-up and placement platform 13 is located in the closed chamber 1, and it is used to provide a pick-up and placement device 5 to place the server 200 taken out from the liquid-cooled device 2. A user outside the closed chamber 1 can take out the server 200 by opening the pick-up and placement door 12; conversely, a user outside the closed chamber 1 can push the server 200 into the portion of the pick-up and placement platform 13 located in the closed chamber 1 through the pick-up and placement opening 11, and the pick-up and placement device 5 and the transfer device 4 can cooperate with each other to move the server 200 on the pick-up and placement platform 13 into one of the liquid-cooled devices 2. Of course, in practice, the closed chamber 1 also includes a personnel access door (not shown) to provide personnel and equipment access.

[0026] A plurality of liquid-cooling devices 2 are disposed in a closed chamber 1. The control device 3 is electrically connected to the pick-and-place device 5 and the transfer device 4, and the control device 3 can control the transfer device 4 to move in the closed chamber 1, and the control device 3 can control the pick-and-place device 5 to take a server 200 out of the liquid-cooling device 2, or to place the server 200 into the liquid-cooling device 2.

[0027] Each liquid-cooling device 2 includes: a tank body 21 and a movable door 22. The tank body 21 is filled with cooling liquid, and the tank body 21 includes a slot 211. The movable door 22 can be controlled to close or not close the slot 211. Multiple servers 200 are arranged in the tank body 21 and immersed in the cooling liquid. In practical applications, the tank body 21 includes, for example, multiple partition structures, and the multiple partition structures together constitute multiple containing tanks, and each server 200 is correspondingly arranged in each containing tank.

[0028] The control device 3 is, for example, an industrial computer. In practice, the control device 3 may be connected to at least one output device A and at least one input device B, and the output device A and the input device B are arranged around the access port 11, and the output device A and the input device B are located outside the closed chamber 1. The output device A is, for example, a screen. The input device B is, for example, a touch screen, a keyboard, a mouse, etc. The relevant personnel may be outside the closed chamber 1, and operate the input device B to control the control device 3. The output device A may, for example, display an operation interface, and the operation interface may, for example, display the operating status of each server 200 arranged in each liquid-cooled device 2, and the relevant personnel may, for example, click on a diagram or option of one of the servers in the operation interface, so that the control device 3 controls the transfer device 4 and the access device 5, takes out the corresponding server 200 from the slot 21, and transfers the server 200 to the access table 13.

[0029] The transfer device 4 and the pick-and-place device 5 are disposed in the closed chamber 1. The pick-and-place device 5 is, for example, a robotic arm. The transfer device 4 includes, for example, wheels, a motor, and other components, and the control device 3 can control the motor to move the transfer device 4 in the closed chamber 1. For example, the transfer device 4 can be, for example, various transport vehicles that can move along a track, or the transfer device 4 can also be a transport vehicle that can move autonomously.

[0030] The control device 3 can control the transfer device 4 and the pick-and-place device 5, so that the transfer device 4 first moves to the vicinity of the tank 21 of the specific liquid-cooled device 2, and then the pick-and-place device 5 takes out one of the servers 200 placed in the tank 21. After the pick-and-place device 5 takes out the server 200, the transfer device 4 will move to the pick-and-place table 13. After the transfer device 4 moves to the pick-and-place table 13, the pick-and-place device 5 can place the server 200 on the pick-and-place table 13, and the relevant personnel outside the closed chamber 1 can take out the server 200 placed on the pick-and-place table 13 through the pick-and-place opening 11.

[0031] In different embodiments, the pick-and-place platform 13 may include a slide rail and a slide table, for example. The pick-and-place device 5 can place the server 200 in the receiving groove of the slide table, and the slide table can move from inside the closed chamber 1 to outside the closed chamber 1 along the slide rail, and the slide table can also move from outside the closed chamber 1 to inside the closed chamber 1 along the slide rail. After the pick-and-place device 5 places the server 200 on the slide table, the control device 3 or the relevant personnel, for example, can control the slide table to move from inside the closed chamber 1 to outside the closed chamber 1 along the slide rail, so that the relevant personnel can take out the server 200 from the slide table.

[0032] Similarly, the control device 3 can control the transfer device 4 and the pick-and-place device 5, first moving the transfer device 4 to the pick-and-place platform 13, and allowing the pick-and-place device 5 to pick up a server 200 placed on the pick-and-place platform 13, and then moving the transfer device 4 to a specific liquid-cooled device 2, and finally, allowing the pick-and-place device 5 to place the server 200 it holds into the slot 21 of the liquid-cooled device 2.

[0033] In a preferred embodiment, the transfer device 4 or the pick-and-place device 5 may include a reader 41, and each liquid-cooled device 2 is provided with a marking unit. The reader 41 can read each marking unit to obtain an identification data stored in the marking unit. The control device 3 can control the transfer device 4 to move the pick-and-place device 5 to one of the liquid-cooled devices 2. The control device 3 can determine whether the transfer device 4 has moved to the correct liquid-cooled device 2 based on the identification data read by the reader 41. The marking unit is, for example, various barcodes, NFC tags, etc., which are not limited here.

[0034] In practice, the pick-and-place device 5 includes, for example, a processor 51, a clamping mechanism 52, and a visual module 53. The processor 51 is electrically connected to the visual module 53 and the clamping mechanism 52. The visual module 53 is used to obtain an image of a predetermined range in front of the clamping mechanism 52 to generate a visual information 531. The processor 51 can control the clamping mechanism 52 according to the visual information 531 to extract the server from the slot 21, or to place the server in the slot 21. Through the design of the visual module 53, the clamping mechanism 52 can more accurately clamp and place the server 200.

[0035] In one embodiment, in order to prevent the server 200 clamped by the pick-and-place device 5 from colliding with other objects in the closed chamber 1 as the transfer device 4 moves in the closed chamber 1, the transfer device 4 may also include a server temporary storage slot 42, which is used to accommodate at least one server 200. After the clamping mechanism 52 takes the server out of the slot 21, the clamping mechanism 52 will place the server 200 in the server temporary storage slot 42. This design can effectively prevent the server 200 from colliding with other objects in the closed chamber 1 during the movement of the transfer device 4.

[0036] In one embodiment, the control device 3 is communicatively connected to a processor 23 of each liquid-cooled device 2, and the control device 3 can transmit a door opening signal 31 to the processor 23, and the processor 23 can open the movable door 22 after receiving the door opening signal 31. The control device 3 can also transmit a door closing signal 32 to the processor 23, and the processor 23 will close the movable door 22 after receiving the door closing signal 32. In different embodiments, the control device 3 can also control the pick-and-place device 5 to open or close the movable door 22.

[0037] It is worth mentioning that, when the server 200 is taken out by the pick-and-place device 5, part of the coolant will leave the tank 21 together with the server 200. Therefore, after the pick-and-place device 5 takes the server 200 out of the tank 21 and makes the server 200 completely leave the coolant, the pick-and-place device 5 can first keep the server 200 in a preset posture for a preset time (for example, 10 to 15 seconds) to allow the coolant on the server 200 to fall back to the tank 21 and part of the coolant to evaporate into the air, and then the server 200 leaves the top of the tank 21.

[0038] When each movable door 22 is opened, part of the coolant will evaporate into the air, and when the server 200 installed in the tank body 21 is taken out, part of the coolant will also evaporate into the air, so the coolant in the tank body 21 will gradually decrease over a long period of time. Therefore, in a preferred embodiment, each tank body 21 can be connected to a coolant supply system 300, and the coolant supply system 300 includes a plurality of pipelines 301, a plurality of control valves 302 and a coolant storage tank 303. The coolant storage tank 303 is connected to each tank body 21 through a plurality of pipelines 301, and each pipeline 301 is provided with a control valve 302.

[0039] Each tank body 21 may be provided with a detector 24. The detector 24 is used to detect the liquid level of the coolant in the tank body 21 to generate a detection information 241. The processor 23 of the liquid-cooled device 2 is electrically connected to the detector 24, so that the processor 23 can determine whether the liquid level of the coolant in the tank body 21 is lower than a preset height based on the detection information 241. If the processor 23 determines that the liquid level of the coolant is lower than the preset height, the processor 23 can control the corresponding control valve 95 so that the coolant in the coolant storage tank 303 flows into the tank body 21 through the pipeline 301 to replenish the coolant in the tank body 21.

[0040] As described above, the liquid-cooled server system 100 of the present invention can allow the relevant personnel to control the control device 3 so that the transfer device 4 and the pick-and-place device 5 can place a specific server 200 into the tank 21 of a specific liquid-cooled device 2, or make the transfer device 4 and the pick-and-place device 5 cooperate with each other to take the server 200 out of the specific tank 21. In addition, by arranging multiple liquid-cooled devices 2 in the closed chamber 1, the coolant will not evaporate to the outside, thereby ensuring the safety of the relevant personnel.

[0041] Please also read Figure 3 and Figure 4 , Figure 3 is a block diagram of a second embodiment of the liquid cooling server system of the present invention, Figure 4 FIG. 4 is a schematic diagram of a second embodiment of a liquid-cooled server system according to the present invention.

[0042] The biggest difference between this embodiment and the previous embodiment is that the liquid-cooled server system 100 may further include a monitoring device 6, an airflow generating device 7, a capturing device 8 and a recovery device 9. The closed chamber 1 is further provided with at least one airflow channel 14, a part of the airflow generating device 7 is provided in the airflow channel 14, the capturing device 8 is provided in the airflow channel 14, and the airflow generating device 7 is used to discharge the gas in the airflow channel 14 into the closed chamber 1. The airflow generating device 7 includes, for example, a fan.

[0043] The number and location of the airflow generating devices 7 and the capturing devices 8 included in the liquid-cooled server 200 can be designed according to actual needs and are not limited to those shown in the figure.

[0044] The monitoring device 6 is used to monitor the concentration of a preset gas in the closed chamber 1 and generate a monitoring information 61. The control device 3 is electrically connected to the monitoring device 6, the airflow generating device 7 and the capturing device 8. Specifically, the monitoring device 6 can monitor the concentration of the preset gas (i.e., the gas after the coolant evaporates) in the closed chamber 1 at any time, and generate the monitoring information 61 accordingly, and the monitoring device 6 can transmit the monitoring information 61 to the control device 3 at any time. After receiving the monitoring information 61, the control device 3 can determine whether the concentration of the preset gas in the closed chamber 1 exceeds the preset concentration based on the monitoring information 61. When the control device 3 determines that the concentration of the preset gas in the closed chamber 1 exceeds the default concentration based on the monitoring information 61, the control device 3 can control the airflow generating device 7 and the capturing device 8 to start (or run at high speed) until the concentration of the preset gas in the closed chamber 1 is lower than the preset concentration, and then control the capturing device 8 to stop running (or run at low speed). When the airflow generating device 7 is activated, the air in the closed chamber 1 is drawn into the capturing device 8, and the capturing device 8 is used to capture the coolant volatilized into gas in the air.

[0045] In practical applications, the capture device 8 includes, for example, a condenser, a suction device and an exhaust device. The condenser includes, for example, a high thermal conductivity pipe body (such as a copper pipe, etc.), one end of the high thermal conductivity pipe body is connected to a cold water source, and the other end is a drain end. The suction device and the exhaust device are arranged on both sides of the condenser. The suction device is used to suck the air in the closed chamber 1. Part of the air sucked in by the suction device will condense into water droplets through the high thermal conductivity pipe body, and the water droplets will flow into the recovery device 9, and the rest of the air will be discharged into the air flow channel 14 by the exhaust device. The airflow generating device 7 can discharge the air in the airflow channel 14 into the closed chamber 1. Since the capture device 8 includes a condenser, the air after passing through the capture device 8 will have a relatively low temperature. Therefore, the air discharged into the closed chamber 1 by the airflow generating device 7 has a relatively low temperature, which can help reduce the temperature in the closed chamber 1.

[0046] In one embodiment, the recovery device 9 may include, for example, a recovery barrel 91, a filter module 92, a plurality of return pipes 93, and at least one pump 94. The recovery barrel 91 is used to accommodate the liquid recovered by the capture device 8. The recovery barrel 91 is connected to a plurality of tanks 21 through a plurality of return pipes 93. The filter module 92 is disposed in the return pipe 93. The filter module 92 is used to filter the coolant flowing from the recovery barrel 91 to the tank 21. The pump 94 is used to allow the coolant to flow into the tank 21 along the return pipe 93.

[0047] Generally speaking, the specific gravity of fluorinated coolant is greater than that of water. Therefore, in the recovery barrel 91, the fluorinated coolant will be located at the bottom of the barrel, and the water will be located above the recovery barrel 91. The return pipe 93 can be connected to the bottom of the recovery barrel 91 to obtain the fluorinated coolant located at the bottom of the recovery barrel 91.

[0048] In practice, each return pipe 93 and each tank body 21 further includes a control valve 95. The control device 3 is electrically connected to each of the aforementioned detectors 24, and when the detector 24 detects that the liquid level in the tank body 21 is lower than a preset height, the control device 3 controls the corresponding control valve 95 to allow the coolant in the return pipe 93 to flow into the tank body 21.

[0049] In different embodiments, the processor in the monitoring device 6 can also determine the concentration of the preset gas in the closed chamber 1 based on the concentration signal. If the concentration of the preset gas exceeds the preset concentration, the processor will send a warning message to the control device 3, and the control device 3 will start the airflow generating device 7 and the capturing device 8 after receiving the warning message.

[0050] In different embodiments, the monitoring device 6 can also monitor the pressure in the closed chamber 1 in real time and generate real-time pressure information. The monitoring device 6 or the control device 3 can determine whether the pressure in the closed chamber 1 exceeds a preset pressure based on the real-time pressure information. When the monitoring device 6 or the control device 3 determines that the pressure in the closed chamber 1 exceeds the preset pressure, the control device 3 can control the capture device 8 and an exhaust device to operate so that the capture device 8 exhausts the air outward through the exhaust device after extracting the air in the closed chamber 1, thereby reducing the pressure in the closed chamber 1.

[0051] When the movable door 22 of the liquid-cooled device 2 is opened, or when the server 200 is taken out of the tank body 21, the coolant will evaporate, and the evaporated coolant will spread in the closed chamber 1, so that the closed chamber 1 is filled with the evaporated coolant. If relevant personnel enter the closed chamber 1 at this time, poisoning may occur. Therefore, through the design of the monitoring device 6 and the capture device 8, it is possible to effectively prevent relevant personnel from entering the closed chamber 1 and being poisoned.

[0052] In actual applications, the capture device 8 can be kept in operation at all times, and the control device 3 determines based on the monitoring information that the concentration of the preset gas in the closed chamber 1 exceeds the preset concentration, or that the pressure in the closed chamber 1 exceeds the preset pressure, and then the suction device of the capture device 8 can be operated at high speed.

[0053] In actual applications, when the control device 3 controls the transfer device 4 and the pick-and-place device 5 to place the server 200 into or take out the slot 21, the control device 3 can also control the airflow generating device 7 to operate at a high speed, so that the airflow generating device 7 generates a relatively strong airflow, so that the air in the closed chamber 1 can flow to the capture device 8.

[0054] As described above, through the design of the monitoring device, the airflow generating device, the capturing device and the recovery device, the concentration of the preset gas in the closed chamber can be effectively controlled, and the coolant evaporated into the air can be effectively recovered so that the coolant can be reused.

[0055] The above description is only a preferred feasible embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the present invention.
