Description

Technical Field

[0001] The present invention relates to the technical field of data centers, and in particular to a data center rack system. Background Art

[0002] A data center is a globally collaborative network of specific devices used to transmit, accelerate, display, calculate, and store data information and other Internet big data on the Internet network infrastructure. Big data refers to a collection of data that cannot be captured, managed, and processed using conventional software tools within a certain time frame. It is a massive, high-growth, and diverse information asset that requires new processing models to have stronger decision-making power, insight discovery, and process optimization capabilities.

[0003] The emergence of big data analysis is aimed at IT management. Enterprises can combine real-time data stream analysis with historical related data, and then analyze big data and find the models they need. The tools for big data analysis generally refer to existing computer equipment. By combining multiple computer processing devices according to a certain organizational framework, a powerful data processing capability can be formed. The analysis tools here generally refer to a server system composed of multiple server units. The server units include cabinets, racks and several server units installed in the racks.

[0004] The server system includes multiple server units. First, the server units need to be in a suitable temperature environment to ensure the maximum operating efficiency of the server units, otherwise it will affect the operating efficiency of the server system. The existing data center rack system used with the server system is responsible for cooling. The existing data center rack system generally uses a cooling fan to run for a long time to cool the server units. However, fan cooling is the most conservative heat dissipation method. When the internal temperature of the server system is too high, the fan cooling loses the best heat dissipation effect. The server system temperature continues to rise, which will cause damage to the server units. Secondly, when the server system temperature is too low, the existing data center rack system lacks a corresponding heating system, resulting in reduced operating efficiency of the server units. Therefore, the present invention provides a data center rack system with temperature monitoring and adjustment functions. Summary of the invention

[0005] In order to solve the technical problems mentioned in the above background technology, a data center rack system is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A data center rack system includes a cabinet and a server unit. A temperature control system is provided in the cabinet.

The temperature sensor detects a temperature C inside the cabinet and converts the temperature signal into a digital signal through an A / D conversion interface. The single-chip microcomputer is provided with a temperature upper limit value A and a temperature lower limit value B. The single-chip microcomputer compares the value of the temperature C with the temperature upper limit value A and the temperature lower limit value B. If the value of the temperature C is greater than the temperature upper limit value A or less than the temperature lower limit value B, the semiconductor refrigerator or the blower is controlled to cool down or heat up the cabinet.

[0008] A conveyor belt and a driving device for driving the conveyor belt to rotate are installed on the cabinet, a server unit is rotatably installed on the conveyor belt, a through slot for accommodating the server unit is opened on one side of the cabinet, a server wiring is connected between the cabinet and the server unit, slide slots are opened on both sides of the cabinet, a support shaft is slidably connected between the slide slots on both sides, a roller connected to the server wiring is sleeved on the support shaft, a telescopic rod is fixedly installed on the cabinet, the free end of the telescopic rod is fixedly connected to a U-shaped frame, the horizontal ends on both sides of the U-shaped frame are rotatably connected to the support shaft, and a spring is sleeved on the outer side of the free end of the telescopic rod.

[0009] As a further description of the above technical solution:

[0010] An early warning system is also provided inside the cabinet, and the early warning system includes a normally open switch, a wireless signal transmitter and a mobile power supply. The normally open switch is installed on one side of the slide slot, and the support shaft presses the normally open switch, the normally open switch is closed, and the wireless signal transmitter is activated to send out an early warning signal.

[0011] As a further description of the above technical solution:

[0012] The cabinet has multiple vents on the top, and filters are installed at the bottom of the vents. A cooling fan is fixedly installed in the vents. When the temperature C is between the temperature upper limit A and the temperature lower limit B, the single chip microcomputer controls the cooling fan to dissipate heat inside the cabinet.

[0013] As a further description of the above technical solution:

[0014] A negative pressure pump is fixedly installed on the top of the cabinet, the output end of the negative pressure pump is connected to an air duct, and multiple output ends of the air duct are connected to multiple negative pressure suction heads at the top of the through groove.

[0015] As a further description of the above technical solution:

[0016] A groove for accommodating the single chip computer, the semiconductor refrigerator, the temperature sensor and the blower is provided on one side of the cabinet, and a heating pipe sleeved on the outside of the air inlet pipe of the blower is installed in the groove.

[0017] As a further description of the above technical solution:

[0018] The driving device comprises an active roller and a driven roller rotatably mounted in a cabinet, a driving motor drivingly connected to the active roller is fixedly mounted on the outside of the cabinet, and the conveyor belt is sleeved on the outside of the active roller and the driven roller.

[0019] As a further description of the above technical solution:

[0020] A fixing seat and a supporting seat are fixedly connected to both sides of the top of the conveyor belt. The fixing seats on both sides are rotatably connected to the server unit through a rotating shaft, and the supporting seat is in contact with the bottom of the server unit.

[0021] As a further description of the above technical solution:

[0022] A plurality of rollers are rotatably mounted on one side of the cabinet close to the through slot, and the rollers are in rolling contact with the server units.

[0023] As a further description of the above technical solution:

[0024] Both ends of the server wiring have a recessed section, and the cabinet and the conveyor belt are fixedly connected with a fixing clip fixedly connected to one end of the recessed section.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, when the internal temperature value C of the cabinet detected by the temperature sensor is greater than the upper temperature limit value A, it indicates that the temperature of the server unit rises to a certain level. At this time, the heat dissipation effect of the cooling fan no longer meets the heat dissipation demand of the server unit. Once the single-chip microcomputer control circuit is turned on, the semiconductor refrigerator is started to cool the inside of the cabinet, and works together with the cooling fan to accelerate the cooling speed inside the cabinet to meet the cooling demand required by the server unit, avoiding the problem of burning the server unit due to excessive internal temperature of the cabinet. During the accelerated cooling process, the internal temperature of the cabinet begins to decrease. When the temperature sensor detects that the internal temperature value C of the cabinet is less than the upper temperature limit value A but greater than the lower temperature limit value B, at this time, the heat dissipation effect of the cooling fan is sufficient to support the heat dissipation demand of the server unit. Once the single-chip microcomputer control circuit is turned off, the semiconductor refrigerator is turned off to ensure normal heat dissipation of the server unit, and avoid resource loss caused by continuous cooling of the semiconductor refrigerator, which is environmentally friendly and energy-saving.

[0027] 2. In the present invention, when the temperature sensor detects that the temperature value C inside the cabinet is less than the lower temperature limit value B, it means that the working temperature of the server unit is too low, which will affect the operating efficiency of the server unit. At this time, the single-chip microcomputer turns off control circuit four, turns off the cooling fan, and no longer dissipates heat inside the cabinet. At the same time, the single-chip microcomputer turns on control circuit two and control circuit three, and the heating pipe heats the air inlet pipe of the blower. The blower continuously sends hot air into the cabinet to heat the inside of the cabinet to avoid the problem of reduced operating efficiency of the server unit due to too low temperature. Similarly, in the process of accelerated heating, the temperature inside the cabinet begins to rise. When the temperature sensor detects that the temperature value C inside the cabinet is less than the upper temperature limit value A but greater than the lower temperature limit value B, the single-chip microcomputer turns off control circuit two and control circuit three, and starts control circuit four. Since the server unit generates heat during operation, the temperature inside the cabinet will continue to rise. Therefore, the cooling fan is also used to dissipate heat inside the cabinet to ensure the normal operation of the server unit.

[0028] 3. In the present invention, under the transmission action of the active roller and the driven roller, the conveyor belt is driven by the driving motor to rotate clockwise, and the server unit moves in the direction close to the through slot. Since the server wiring is fixed in length, one end of the server wiring moves synchronously with the server unit, and the other end of the server wiring squeezes the spring and the free end of the telescopic rod. The free end of the telescopic rod pulls the U-shaped frame, the rotating roller and the support shaft to slide in the slide slot. The server unit completely comes to the outside of the through slot, the support shaft squeezes the normally open switch, closes the normally open switch, and the wireless signal transmitter sends a warning signal to the service center. When the server unit is completely pulled out of the cabinet, the maintenance personnel can inspect the server unit. During the maintenance process, the server wiring moves in an orderly manner with the server unit to avoid the occurrence of wiring entanglement and other phenomena, which is convenient for maintenance work.

[0029] 4. In the present invention, after the normally open switch is closed, the control circuit five is connected, and the mobile power supply supplies power to the wireless signal transmitter. The wireless signal transmitter immediately sends an early warning signal to the service center to remind the management personnel that the server unit has been pulled out of the cabinet. The maintenance personnel retrieve the server unit repaired by the maintenance personnel according to the fault record table to see whether it is the same as the faulty server unit, so as to avoid the maintenance personnel repairing the non-faulty server unit and causing maintenance errors, or avoid the maintenance personnel stealing the data information in the non-faulty server unit, thereby improving the security protection mechanism of the data center.

[0041] 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. Embodiment 1

[0042] See also Figure 1-9 The present invention provides a technical solution: a data center rack system, including a cabinet 1 and a server unit 4, a temperature control system is arranged in the cabinet 1, the temperature control system includes a single chip computer 12, a semiconductor refrigerator 13, a temperature sensor 14 and a blower 22, a groove 11 for accommodating the single chip computer 12, the semiconductor refrigerator 13, the temperature sensor 14 and the blower 22 is opened on one side of the cabinet 1, and a heating pipe 33 sleeved on the outside of the air inlet pipe of the blower 22 is installed in the groove 11, the temperature sensor 14 detects the internal temperature C of the cabinet 1, and converts the temperature signal into a digital signal through an A / D conversion interface, and the single chip computer 12, the semiconductor refrigerator 13, the temperature sensor 14 and the blower 22 are arranged on one side of the cabinet 1. The cabinet 12 is provided with a temperature upper limit value A and a temperature lower limit value B. The single chip computer 12 compares the value of temperature C with the temperature upper limit value A and the temperature lower limit value B. If the value of temperature C is greater than the temperature upper limit value A or less than the temperature lower limit value B, the semiconductor refrigerator 13 or the blower 22 is controlled to cool down or heat up the cabinet 1. The cabinet 1 has a plurality of vents 3 on the top, and a filter screen 27 is installed at the bottom of the vents 3. A cooling fan 5 is fixedly installed in the vents 3. When the value of temperature C is between the temperature upper limit value A and the temperature lower limit value B, the single chip computer 12 controls the cooling fan 5 to dissipate heat inside the cabinet 1.

[0043] Specifically, the operation mode of the temperature control system is shown in Table 1 below:

[0044] Table 1

[0045]

[0046] When the temperature value C inside the cabinet 1 detected by the temperature sensor 14 is greater than the upper temperature limit A, it indicates that the temperature of the server unit 4 rises to a certain level. At this time, the heat dissipation effect of the cooling fan 5 no longer meets the heat dissipation demand of the server unit 4. Once the control circuit is turned on by the single-chip microcomputer 12, the semiconductor refrigerator 13 is started to cool the inside of the cabinet 1. The semiconductor refrigerator 13 works together with the cooling fan 5 to accelerate the cooling speed inside the cabinet 1 to meet the cooling demand required by the server unit 4, thereby avoiding the problem of burning the server unit 4 due to excessive temperature inside the cabinet 1.

[0047] During the accelerated cooling process, the temperature inside the cabinet 1 begins to decrease. When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the upper temperature limit value A but greater than the lower temperature limit value B, at this time, the heat dissipation effect of the cooling fan 5 is sufficient to support the heat dissipation demand of the server unit 4. The single-chip microcomputer 12 controls the control circuit to be turned off, and then turns off the semiconductor refrigerator 13, ensuring the normal heat dissipation of the server unit 4, and avoiding the resource loss caused by the continuous cooling of the semiconductor refrigerator 13, which is environmentally friendly and energy-saving;

[0048] When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the lower temperature limit value B, it means that the working temperature of the server unit 4 is too low, which will affect the operation efficiency of the server unit 4. At this time, the single chip computer 12 turns off the control circuit four, turns off the cooling fan 5, and no longer dissipates heat inside the cabinet 1. At the same time, the single chip computer 12 turns on the control circuit two and the control circuit three, and the heating pipe 33 heats the air inlet pipe of the blower 22. The blower 22 continuously sends hot air into the cabinet 1 to heat the inside of the cabinet 1 to avoid the problem of reduced operation efficiency of the server unit 4 due to too low temperature. Similarly, in the accelerated heating process, the temperature inside the cabinet 1 begins to rise. When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the upper temperature limit value A but greater than the lower temperature limit value B, the single chip computer 12 turns off the control circuit two and the control circuit three, and starts the control circuit four. Since the server unit 4 generates heat during operation, the temperature inside the cabinet 1 will continue to rise. Therefore, the cooling fan 5 is also used to dissipate heat inside the cabinet 1 to ensure the normal operation of the server unit 4.

[0049] The connection between the control circuit and the cooling fan 5, the semiconductor refrigerator 13, the blower 22 and the heating tube 33, and the on / off control of the control circuit are prior art, so they are not described here in detail.

[0050] An early warning system is also provided inside the cabinet 1, and the early warning system includes a normally open switch 24, a wireless signal transmitter 25 and a mobile power supply 26. The normally open switch 24 is installed on one side of the slide slot 23, and the support shaft 16 presses the normally open switch 24, the normally open switch 24 is closed, and the wireless signal transmitter 25 is activated to send out an early warning signal;

[0051] After the normally open switch 24 is closed, the control circuit five is connected, and the mobile power supply 26 supplies power to the wireless signal transmitter 25. The wireless signal transmitter 25 immediately sends a warning signal to the service center to remind the management personnel that the server unit 4 is pulled out of the cabinet 1. The maintenance personnel retrieve the server unit 4 repaired by the maintenance personnel according to the fault record table to see whether it is the same as the faulty server unit 4, so as to avoid the maintenance personnel repairing the non-faulty server unit 4 and causing maintenance errors, or avoid the maintenance personnel stealing the data information in the non-faulty server unit 4, thereby improving the security protection mechanism of the data center.

[0052] A conveyor belt 20 and a driving device for driving the conveyor belt 20 to rotate are installed on the cabinet 1. The driving device includes an active roller 21 and a driven roller 10 rotatably installed in the cabinet 1. A driving motor 29 connected to the active roller 21 is fixedly installed on the outside of the cabinet 1. The conveyor belt 20 is sleeved on the outside of the active roller 21 and the driven roller 10. A server unit 4 is rotatably installed on the conveyor belt 20. A through groove 9 for accommodating the server unit 4 is opened on one side of the cabinet 1. A server wiring 2 is connected between the cabinet 1 and the server unit 4. Slide grooves 23 are opened on both sides of the cabinet 1. A support shaft 16 is slidably connected between the slide grooves 23 on both sides. A roller 15 connected to the server wiring 2 is sleeved on the support shaft 16. A telescopic rod 19 is fixedly installed on the cabinet 1. The free end of the telescopic rod 19 is fixedly connected to a U-shaped frame. The horizontal ends of the two sides of the U-shaped frame are rotatably connected to the support shaft 16. A spring 17 is sleeved on the outside of the free end of the telescopic rod 19.

[0053] Under the transmission action of the active roller 21 and the driven roller 10, the conveyor belt 20 is driven by the driving motor 29 to rotate clockwise, and the server unit 4 moves in the direction close to the through slot 9. Since the server wiring 2 is fixed in length, one end of the server wiring 2 moves synchronously with the server unit 4, and the other end of the server wiring 2 squeezes the spring 17 and the free end of the telescopic rod 19. The free end of the telescopic rod 19 pulls the U-shaped frame, the roller 15 and the support shaft 16 to slide in the slide slot 23. The server unit 4 completely comes to the outside of the through slot 9, and the support shaft 16 squeezes the normally open switch 24, closes the normally open switch 24, and the wireless signal transmitter 25 sends a warning signal to the service center. When the server unit 4 is completely pulled out of the cabinet 1, the maintenance personnel can repair the server unit 4. During the maintenance process, the server wiring 2 moves in an orderly manner with the server unit 4 to avoid the occurrence of wiring entanglement and other phenomena, which is convenient for maintenance work.

[0054] Similarly, when the drive motor 29 reverses, the server unit 4 enters the cabinet 1, and the end of the server wiring 2 away from the server unit 4 gradually relaxes. Under the action of the spring 17, the roller 15 is pushed back to its original position through the free end of the telescopic rod 19. In this process, the server wiring 2 is always in a taut state, thereby preventing the server wiring 2 from being entangled with other components inside the cabinet 1, ensuring the orderly connection of the server wiring 2, wherein the support shaft 16 leaves the normally open switch 24, the normally open switch 24 is disconnected, the control circuit five is immediately disconnected, and the wireless signal transmitter 25 enters the standby state.

[0055] See also Figure 1 and Figure 3A negative pressure pump 6 is fixedly installed on the top of the cabinet 1, and the output end of the negative pressure pump 6 is connected to an air duct 7, and multiple output ends of the air duct 7 are connected to multiple negative pressure suction heads 8 at the top of the through slot 9. When thick dust accumulates on the top of the server unit 4, when the server unit 4 enters and exits the through slot 9, the negative pressure pump 6 is started, and the dust on the surface of the server unit 4 is adsorbed by the negative pressure suction head 8, thereby achieving the purpose of cleaning the dust on the surface of the server unit 4.

[0056] See also Figure 7 A fixing seat 30 and a supporting seat 32 are fixedly connected to both sides of the top of the conveyor belt 20. The fixing seats 30 on both sides are rotatably connected to the server unit 4 through the rotating shaft 31. The supporting seat 32 contacts the bottom of the server unit 4. After the server unit 4 completely passes through the through slot 9, since one end of the server unit 4 is rotatably connected to the conveyor belt 20, the maintenance personnel can rotate the server unit 4 during the maintenance process to conduct a more comprehensive inspection of the server unit 4.

[0057] See also Figure 4 A plurality of rollers 28 are rotatably installed on one side of the cabinet 1 close to the through slot 9. The rollers 28 are in rolling contact with the server unit 4. There is a certain distance between the conveyor belt 20 and the through slot 9. When the server unit 4 moves toward the through slot 9, first, the free end of the server unit 4 contacts the rollers 28 to prevent the free end of the server unit 4 from being suspended in the air and getting stuck between the conveyor belt 20 and the through slot 9.

[0058] See also Figure 1 Both ends of the server wiring 2 have a recessed section, and the cabinet 1 and the conveyor belt 20 are fixedly connected with a fixing clip 18 fixedly connected to one end of the recessed section, so as to avoid the problem of breakage at the connection between the two ends of the server wiring 2 and the server unit 4 or the cabinet 1 during the tightening process of the server wiring 2, thereby improving the service life of the server wiring 2.

[0059] Working principle: When in use, first, when the temperature value C inside the cabinet 1 detected by the temperature sensor 14 is greater than the upper temperature limit A, it means that the temperature of the server unit 4 rises to a certain extent. At this time, the heat dissipation effect of the cooling fan 5 no longer meets the heat dissipation demand of the server unit 4. Once the control circuit is turned on by the single-chip microcomputer 12, the semiconductor refrigerator 13 is started to cool the inside of the cabinet 1, and it works together with the cooling fan 5 to accelerate the cooling speed inside the cabinet 1, so as to meet the cooling demand required by the server unit 4, and avoid the problem of burning the server unit 4 due to the excessive temperature inside the cabinet 1;

[0060] During the accelerated cooling process, the temperature inside the cabinet 1 begins to decrease. When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the upper temperature limit value A but greater than the lower temperature limit value B, at this time, the heat dissipation effect of the cooling fan 5 is sufficient to support the heat dissipation demand of the server unit 4. The single-chip microcomputer 12 controls the control circuit to be turned off, and then turns off the semiconductor refrigerator 13, ensuring the normal heat dissipation of the server unit 4, and avoiding the resource loss caused by the continuous cooling of the semiconductor refrigerator 13, which is environmentally friendly and energy-saving;

[0061] When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the lower temperature limit value B, it means that the working temperature of the server unit 4 is too low, which will affect the operation efficiency of the server unit 4. At this time, the single chip computer 12 turns off the control circuit four, turns off the cooling fan 5, and no longer dissipates heat inside the cabinet 1. At the same time, the single chip computer 12 turns on the control circuit two and the control circuit three, and the heating pipe 33 heats the air inlet pipe of the blower 22. The blower 22 continuously sends hot air into the cabinet 1 to heat the inside of the cabinet 1 to avoid the problem of reduced operation efficiency of the server unit 4 due to too low temperature. Similarly, in the accelerated heating process, the temperature inside the cabinet 1 begins to rise. When the temperature sensor 14 detects that the temperature value C inside the cabinet 1 is less than the upper temperature limit value A but greater than the lower temperature limit value B, the single chip computer 12 turns off the control circuit two and the control circuit three, and starts the control circuit four. Since the server unit 4 generates heat during operation, the temperature inside the cabinet 1 will continue to rise. Therefore, the cooling fan 5 is also used to dissipate heat inside the cabinet 1 to ensure the normal operation of the server unit 4.

[0062] Secondly, under the transmission action of the active roller 21 and the driven roller 10, the conveyor belt 20 is driven by the driving motor 29 to rotate clockwise, and the server unit 4 moves toward the direction close to the through slot 9. Since the server wiring 2 is fixed in length, one end of the server wiring 2 moves synchronously with the server unit 4, and the other end of the server wiring 2 squeezes the spring 17 and the free end of the telescopic rod 19. The free end of the telescopic rod 19 pulls the U-shaped frame, the rotating roller 15 and the support shaft 16 to slide in the slide slot 23. The server unit 4 completely comes to the outside of the through slot 9, and the support shaft 16 squeezes the normally open switch 24, closes the normally open switch 24, connects the control circuit 5, and the mobile power supply 26 supplies power to the wireless signal transmitter 25, and the wireless signal transmitter 25 sends An early warning signal is sent to the service center to remind the management personnel that the server unit 4 is pulled out of the cabinet 1. The maintenance personnel retrieve whether the server unit 4 being repaired by the maintenance personnel is the same as the faulty server unit 4 according to the fault record table, so as to avoid the maintenance personnel repairing the non-faulty server unit 4 and causing maintenance errors, or to avoid the maintenance personnel stealing the data information in the non-faulty server unit 4, thereby improving the security protection mechanism of the data center. When the server unit 4 is completely pulled out of the cabinet 1, the maintenance personnel can repair the server unit 4. During the maintenance process, the server wiring 2 moves in an orderly manner with the server unit 4, so as to avoid the occurrence of wiring entanglement and the like, and facilitate the maintenance work.

[0063] Similarly, when the drive motor 29 reverses, the server unit 4 enters the cabinet 1, and the end of the server wiring 2 away from the server unit 4 gradually relaxes. Under the action of the spring 17, the roller 15 is pushed back to its original position through the free end of the telescopic rod 19. In this process, the server wiring 2 is always in a taut state, thereby preventing the server wiring 2 from being entangled with other components inside the cabinet 1, ensuring the orderly connection of the server wiring 2, wherein the support shaft 16 leaves the normally open switch 24, the normally open switch 24 is disconnected, the control circuit five is immediately disconnected, and the wireless signal transmitter 25 enters the standby state.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
