Abstract

This invention discloses a rack-mounted industrial control computer for big data servers, relating to the field of industrial control computer technology. It includes an outer casing and a main unit chassis, with the main unit chassis fixedly installed inside the outer casing. The outer casing has two air vents, a first vent and a second vent. Protective filters are movably connected to the outer surface of the outer casing, outside both air vents. This invention uses a movable sealing mechanism to seal air vents, making the interior of the outer casing essentially a completely sealed mechanism. Any residual air inside the outer casing is filtered and dried by the protective filters before entering, resulting in very little moisture content.

Description

Technical Field

[0001] This invention relates to the field of industrial control computer technology, and specifically to a rack-mounted industrial control computer for big data servers. Background Technology

[0002] Industrial control computers (IPCs) are ruggedized special-purpose computers designed specifically for industrial environments. Their core objective is to achieve stable, uninterrupted operation 24 / 7 under harsh and complex working conditions. They undertake core functions such as industrial control, data acquisition, equipment monitoring, and edge computing, serving as the core "control brain" for industrial automation, intelligent manufacturing, and industrial digitalization.

[0003] A search revealed Chinese Patent Publication No. CN119781587B, which discloses a heat dissipation device for an industrial control computer. The technical solution includes: a chassis, in which a motherboard is fixedly installed; a wiring port electrically connected to the motherboard is fixedly installed on the chassis; a heat sink is fixedly installed inside the chassis and fixedly connected to the motherboard; a heat dissipation box fixedly installed on the chassis; multiple air guide shrouds fixedly installed inside the heat dissipation box; and a gas distribution component installed inside the heat dissipation box. This invention uses a fan assembly to deliver gas to multiple air guide shrouds and a distribution mechanism to rationally distribute the gas volume entering different air guide shrouds. This allows for meeting the heat dissipation needs of different locations on the heat sink even when the output power of the fan assembly is relatively low, without needing to increase the output power of the fan assembly, thus effectively reducing energy consumption.

[0004] The aforementioned patent utilizes a fan to create convection between the inside of the chassis and the external environment, ensuring efficient heat exchange and thus meeting the chassis's cooling requirements. However, frequent internal and external convection causes the airflow entering the chassis to carry a large amount of moisture. In low-temperature environments, the industrial computer generates significant heat during operation, and when it stops working, the internal temperature of the chassis drops rapidly. This alternating hot and cold environment, combined with the moisture-laden airflow, easily leads to condensation inside the chassis, causing short circuits on circuit boards, pin oxidation and rust, and intermittent contact problems over long-term operation. Summary of the Invention

[0005] This invention provides a rack-mounted industrial control computer for big data servers to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A rack-mounted industrial control computer for big data servers includes an outer casing and a main unit chassis. The main unit chassis is fixedly installed inside the outer casing. The outer casing has two air vents, and protective filters are movably connected to the outer surface of the outer casing outside the air vents. A temperature sensor is fixedly installed on the outer casing.

[0007] The outer peripheral surface of the main unit is fixedly connected to an inner heat dissipation fin, and the outer shell is embedded with an outer heat dissipation fin. The inner heat dissipation fin and the outer heat dissipation fin are arranged in a one-to-one correspondence, and a movable preheating mechanism is provided between the inner heat dissipation fin and the outer heat dissipation fin.

[0008] The outer casing is equipped with a movable sealing mechanism inside to seal air vent one and air vent two.

[0009] A further improvement of the technical solution of the present invention is that: the active preheating mechanism includes a heat-conducting plate movably connected to the outer surface of the main unit chassis, the heat-conducting plate is embedded with multiple heating components, and the heat-conducting plate is provided with multiple connecting grooves, the inner wall of the connecting grooves being movably connected to the outer surface of the inner heat dissipation fins and the outer heat dissipation fins.

[0010] A further improvement of the technical solution of the present invention is that: the inner heat dissipation fins and the outer heat dissipation fins are in a separated state. When the ambient temperature is low, the heat conduction plate abuts against the outer surface of the host chassis, the heating component works, and the host chassis is preheated. At this time, the outer heat dissipation fins do not contact the heat conduction plate.

[0011] When the ambient temperature is high, the host chassis generates heat during operation. The heat dissipation plate moves to connect with the external heat dissipation fins, which then conduct the heat generated by the host chassis to the external environment, ensuring proper heat dissipation of the host chassis.

[0012] A further improvement of the technical solution of the present invention is that: an electromagnet is fixedly connected to the heat-conducting plate, and a magnetic block is fixedly connected to the main unit chassis accordingly.

[0013] A further improvement of the technical solution of the present invention is that: a guide rod is fixedly connected to the heat-conducting plate, a corresponding connecting groove is provided on the main unit box, the guide rod is movably connected to the connecting groove, and a spring is fixedly connected to the bottom of the inner cavity of the connecting groove.

[0014] A further improvement of the technical solution of the present invention is that: the movable sealing mechanism includes two sealing sleeves fixedly connected inside the outer shell, the two sealing sleeves respectively covering the areas of air vent one and air vent two located inside the outer shell, and air vent three is opened on the sealing sleeve.

[0015] The sealing sleeve is movably connected to a sealing plug. Limiting support rods are fixedly connected to both sides of the sealing plug. A guide rod is movably connected through the limiting support rod. The two ends of the guide rod are fixedly connected to the inside of the outer shell.

[0016] A further improvement of the technical solution of the present invention is that: an electromagnet is fixedly connected to one of the sealing plugs, and a magnetic block is fixedly connected to the other sealing plug.

[0017] A further improvement of the technical solution of the present invention is that: the electromagnet II is electrically connected to two fixed electrodes through wires, and the fixed electrodes are connected to the guide rod through a fixing frame I.

[0018] Each of the fixed electrodes has a movable electrode movably connected to its inner side, and the two movable electrodes are electrically connected to an external power supply via wires.

[0019] A further improvement of the technical solution of the present invention is that: a driven gear is fixedly connected to the bottom of the movable electrode, and a second fixed frame is movably connected to the bottom of the driven gear, and the second fixed frame is connected to the guide rod.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides a rack-mount industrial control computer for big data servers. In low-temperature environments, the movable sealing mechanism in this application operates to seal air vent one and air vent two. At this time, the interior of the outer casing can be considered a completely sealed mechanism. The air remaining inside the outer casing is filtered and dried by the protective filter before entering the outer casing. Therefore, the moisture content of the air remaining inside the outer casing is very low. Thus, in low-temperature environments, when the main unit is working or not working, the condensation phenomenon that may occur due to temperature changes is reduced as much as possible, thereby reducing the possibility of problems such as short circuits on circuit boards, pin oxidation and rust, and intermittent poor contact during long-term operation.

[0021] 2. This invention provides a rack-mount industrial control computer for big data servers. When the main unit is working, it generates a large amount of heat. The heat generated by the main unit can be conducted to the outside of the outer shell through the cooperation of the movable preheating mechanism, the inner heat dissipation fins and the outer heat dissipation fins, so as to exchange heat with the external environment and improve the heat dissipation efficiency of the main unit. At the same time, in low temperature environment, the main unit is preheated by the movable preheating mechanism before the core components are started, so as to avoid cold start shock, which may cause equipment failure and cold damage to components.

[0022] 3. This invention provides a rack-mount industrial control computer for big data servers. When the ambient temperature is low, electromagnet two is energized. At this time, the magnetic poles of electromagnet two and magnetic block two on opposite sides are in the same direction, generating a repulsive force that causes the two sealing plugs to move into the sealing sleeve until vent one and vent two are sealed. When it is necessary to release the sealing state inside the outer shell, the current direction of electromagnet two is changed, and the magnetic pole direction of electromagnet two is changed. At this time, the magnetic poles of electromagnet two and magnetic block two on opposite sides are in different directions, generating a magnetic attraction that causes the two sealing plugs to move out of the sealing sleeve through the limiting support rod until the inside of the outer shell is connected to the external environment through vent three, vent one, and vent two.

[0025] The present invention will be further described in detail below with reference to embodiments: Example

[0026] like Figure 1-11As shown, this invention provides a rack-mounted industrial control computer for big data servers, including an outer casing 1 and a main unit chassis 6. The main unit chassis 6 is fixedly installed inside the outer casing 1. Both the outer casing 1 and the main unit chassis 6 are existing technologies. The outer casing 1 and the main unit chassis 6 are equipped with multiple RS232 / 485 serial ports, CAN bus, opto-isolated GPIO, and multiple gigabit / 10-gigabit industrial network ports as needed, natively adapting to various industrial peripherals and sensors. The outer casing 1 has two vents, 2 and 3, for easy heat dissipation. Both vent 1 (2) and vent 2 (3) are sealed structures. One side of each vent is movably connected to an inspection door (5) for easy inspection and maintenance of the interior of the outer casing 1. Protective filters (4) are movably connected to the outer surface of the outer casing 1, outside of vent 1 (2) and vent 2 (3). The protective filters (4) are existing technology and mainly consist of a filtration structure and a drying structure. They filter and dry the airflow entering the interior of the outer casing 1. A temperature sensor is fixedly installed on the outer casing 1 to monitor the ambient temperature of the outer casing 1 and the main unit 6 in real time.

[0027] It also includes a PLC control system and other related equipment, which are electrically connected to each electrical control device in this application to ensure the real-time performance and accuracy of control commands and to adapt to the continuous operation requirements of each structure in this application.

[0028] An inner heat dissipation fin 7 is fixedly connected to the outer peripheral surface of the main unit chassis 6, and an outer heat dissipation fin 8 is embedded on the outer shell 1. The inner heat dissipation fin 7 and the outer heat dissipation fin 8 are arranged in a one-to-one correspondence. A movable preheating mechanism is provided between the inner heat dissipation fin 7 and the outer heat dissipation fin 8. Both the inner heat dissipation fin 7 and the outer heat dissipation fin 8 are made of thermally conductive materials. When the main unit chassis 6 is working, it will generate a lot of heat. The heat generated by the main unit chassis 6 can be conducted to the outside of the outer shell 1 through the cooperation of the movable preheating mechanism, the inner heat dissipation fin 7 and the outer heat dissipation fin 8, and heat exchange with the external environment, thereby improving the heat dissipation efficiency of the main unit chassis 6. At the same time, in low temperature environments, the main unit chassis 6 is preheated by the movable preheating mechanism before the core components are started, so as to avoid cold start shock, which may cause equipment failure and cold damage to components.

[0029] The outer casing 1 is equipped with a movable sealing mechanism inside to seal the air vent 1 2 and air vent 2 3.

[0030] In low-temperature environments, the active sealing mechanism in this application operates to seal air vent 2 and air vent 3. At this time, the interior of the outer casing 1 can be considered a completely sealed mechanism. The air remaining inside the outer casing 1 is filtered and dried by the protective filter 4 before entering the outer casing 1. Therefore, the moisture content of the air remaining inside the outer casing 1 is very low. Thus, in low-temperature environments, when the main unit 6 is working or not working, the condensation phenomenon that may occur due to temperature changes is reduced as much as possible, thereby reducing the possibility of short circuits on the circuit board, oxidation and rusting of pins, and intermittent poor contact during long-term operation.

[0031] When the outer casing 1 and the main unit 6 are working in a low-temperature environment, the movable sealing mechanism will seal the air vent 1 2 and air vent 2 3. If the main unit 6 generates a lot of heat during operation, the movable preheating mechanism, the inner heat dissipation fins 7, and the outer heat dissipation fins 8 can be used to dissipate heat from the main unit 6, so as to avoid heat accumulation, overheating of the main unit 6, and affecting its working performance.

[0032] When operating under normal temperature conditions, the movable sealing mechanism opens the air vents 1 and 2, allowing the airflow inside the outer casing 1 to exchange heat with the external environment. Combined with the heat dissipation treatment of the inner heat dissipation fins 7, the outer heat dissipation fins 8, and the movable preheating mechanism, the heat dissipation efficiency of the main unit 6 is improved.

[0033] Furthermore, such as Figure 3-7 As shown, the active preheating mechanism includes a heat-conducting plate 9 movably connected to the outer surface of the main unit chassis 6. The heat-conducting plate 9 is made of a heat-conducting material, and multiple heating components 10 are embedded inside the heat-conducting plate 9. The heating components 10 are existing technologies and are low-power constant-temperature heating structures. Multiple connecting grooves 11 are provided on the heat-conducting plate 9. The inner wall of the connecting groove 11 is movably connected to the outer surface of the inner heat dissipation fins 7 and the outer heat dissipation fins 8. The connecting grooves 11, the inner heat dissipation fins 7, and the outer heat dissipation fins 8 are correspondingly arranged.

[0034] Furthermore, the inner heat dissipation fins 7 and the outer heat dissipation fins 8 are in a separated state. When the ambient temperature is low, the heat conduction plate 9 abuts against the outer surface of the main unit 6, and the heating component 10 works to preheat the main unit 6. At this time, the outer heat dissipation fins 8 and the heat conduction plate 9 are not in contact.

[0035] When the ambient temperature is high, the host chassis 6 generates heat during operation. The heat conduction plate 9 moves to connect with the external heat dissipation fins 8, and the heat generated by the host chassis 6 is conducted to the external environment through the external heat dissipation fins 8, ensuring the heat dissipation efficiency of the host chassis 6.

[0036] Furthermore, an electromagnet 12 is fixedly connected to the heat-conducting plate 9, and a magnetic block 13 is fixedly connected to the main unit 6. The magnetic block 13 is a permanent magnet and the magnetic pole direction is fixed.

[0037] When the ambient temperature is low, when the host case 6 starts up, electromagnet 12 is energized. The magnetic pole direction of electromagnet 12 is different from that of the opposite side of magnetic block 13, creating a magnetic attraction on magnetic block 13, causing heat conduction plate 9 to adhere to the host case 6. At this time, heating component 10 works, preheating the host case 6 through the heat conduction of heat conduction plate 9 and internal heat dissipation fins 7 until the host case 6 starts up. At this time, heating component 10 stops working. If the host case 6 generates little heat and the temperature rise is low, no additional heat dissipation is needed, and heat conduction plate 9 remains attached to the surface of the host case 6. If the host case 6 generates a lot of heat and the temperature rise is high, additional heat dissipation is needed. For additional heat dissipation, the direction of the current that generates magnetism when connected to the magnetic block 13 changes, causing the magnetic pole direction of the magnetic block 13 to change. At this time, the magnetic pole directions of the electromagnet 12 and the magnetic block 13 on opposite sides are the same, generating a repulsive force. This causes the heat-conducting plate 9 to detach from the surface of the main unit 6 and move to the position where the separated inner heat dissipation fins 7 and outer heat dissipation fins 8 are connected. The inner heat dissipation fins 7, outer heat dissipation fins 8, and heat-conducting plate 9 form a complete heat conduction path, allowing the heat generated by the main unit 6 to be conducted to the outside of the outer shell 1 through the outer heat dissipation fins 8 for heat exchange with the external environment, thus facilitating the heat dissipation of the main unit 6.

[0038] Furthermore, a guide rod 14 is fixedly connected to the heat-conducting plate 9, and a corresponding connecting groove 15 is provided on the main unit box 6. The guide rod 14 is movably connected to the connecting groove 15, and a spring 32 is fixedly connected to the bottom of the inner cavity of the connecting groove 15.

[0039] One end of the guide rod 14 located inside the connecting groove 15 is fixedly connected to a limiting plate, which limits the range of movement of the heat-conducting plate 9 along the inner heat dissipation fins 7 and the outer heat dissipation fins 8. This ensures that when the heat-conducting plate 9 is attached to the main unit 6, the outer heat dissipation fins 8 do not contact the inner heat dissipation fins 7 and the heat-conducting plate 9. When the heat-conducting plate 9 is not attached to the main unit 6, the inner heat dissipation fins 7 and the outer heat dissipation fins 8 can be connected through the connecting groove 11 opened on the heat-conducting plate 9, which facilitates the heat dissipation of the main unit 6.

[0040] When the magnetic block 13 is made of a conventional magnetic material, the electromagnet 12 is energized to generate a magnetic attraction, causing the heat-conducting plate 9 to adhere to the surface of the main unit 6. At this time, the guide rod 14 extends into the connecting groove 15 and compresses the spring 32 to cause it to undergo elastic deformation. When the electromagnet 12 is de-energized, the magnetic attraction disappears. Under the action of the compressed spring 32, the heat-conducting plate 9 is pushed out and does not contact the surface of the main unit 6. The inner heat dissipation fins 7, the outer heat dissipation fins 8, and the heat-conducting plate 9 are connected by the connecting groove 11 to form a heat conduction path on the surface of the main unit 6.

[0041] Furthermore, such as Figure 8-11As shown, the movable sealing mechanism includes two sealing sleeves 16 fixedly connected inside the outer shell 1. The two sealing sleeves 16 respectively cover the areas of air vent 1 2 and air vent 2 3 located inside the outer shell 1. An air vent 3 17 is opened on the sealing sleeve 16. A duct 21 is fixedly connected to the outside of one of the sealing sleeves 16. One end of the duct 21 covers the air vent 3 17. A fan 22 is fixedly connected inside the duct 21.

[0042] A sealing plug 18 is movably connected inside the sealing sleeve 16. Limiting support rods 19 are fixedly connected to both sides of the sealing plug 18. A guide rod 20 is movably connected through the inside of the limiting support rod 19. The two ends of the guide rod 20 are fixedly connected to the inside of the outer shell 1.

[0043] When the ambient temperature is low and it is necessary to keep the inside of the outer shell 1 sealed, the two sealing plugs 18 move along the guide rod 20 to the inside of the sealing sleeve 16 through the limiting support rod 19 until the surface of the sealing plug 18 abuts against the inner wall of the outer shell 1. At this time, the air vent 1 2 and air vent 2 3 are completely sealed.

[0044] When the ambient temperature is high and it is necessary to connect the inside of the outer casing 1 with the external environment, the two sealing plugs 18 move along the guide rod 20 to the outside of the sealing sleeve 16 via the limiting support rod 19 until the sealing plugs 18 move to fully expose the air vent 17. At this time, the inside of the outer casing 1 is connected to the external environment through the air vent 17, the sealing sleeve 16, the air vent 2, and the air vent 3. Airflow is formed between the inside of the outer casing 1 and the external environment, generating heat exchange and assisting the main unit 6 in heat dissipation.

[0045] When the fan 22 starts, it will accelerate the introduction of cold air from the outside environment into the outer casing 1 through air outlet 2 or air outlet 3. After sufficient heat exchange with the main unit 6, the air will be discharged to the outside of the outer casing 1 through air outlet 3 or air outlet 2, thereby improving the heat dissipation efficiency of the main unit 6.

[0046] Furthermore, one of the sealing plugs 18 is fixedly connected to an electromagnet 23, and the other sealing plug 18 is fixedly connected to a magnetic block 26. The magnetic block 26 is a permanent magnet with a fixed magnetic pole direction. When the ambient temperature is low, the electromagnet 23 is energized. At this time, the magnetic pole directions of the opposite sides of the electromagnet 23 and the magnetic block 26 are the same, generating a repulsive force, causing the two sealing plugs 18 to move into the sealing sleeve 16 until the air vent 12 and air vent 23 are sealed. When it is necessary to release the sealing state inside the outer shell 1, the current direction of the electromagnet 23 is changed, and the magnetic pole direction of the electromagnet 23 is changed. At this time, the magnetic pole directions of the opposite sides of the electromagnet 23 and the magnetic block 26 are different, generating a magnetic attraction, causing the two sealing plugs 18 to move out of the sealing sleeve 16 through the limiting support rod 19 until the inside of the outer shell 1 is connected to the external environment through the air vent 317, air vent 12, and air vent 23.

[0047] Furthermore, electromagnet 23 is electrically connected to two fixed electrodes 24 via wires. The fixed electrodes 24 are made of conductive material and are connected to the guide rod 20 via a fixing bracket 25. The two fixed electrodes 24 are symmetrically arranged about the center point of the driven gear 28. Both the fixed electrodes 24 and the movable electrode 27 are arc-shaped.

[0048] Each fixed electrode 24 has a movable electrode 27 movably connected to its inner side. The movable electrode 27 is made of conductive material. The two movable electrodes 27 are electrically connected to an external power supply through wires. A driven gear 28 is fixedly connected to the bottom of the movable electrode 27. A fixed frame 31 is movably connected to the bottom of the driven gear 28. The fixed frame 31 is connected to the guide rod 20. A drive device for driving the driven gear 28 to rotate is installed on the fixed frame 31. The drive device includes a driving gear 29 that meshes with the driven gear 28. The driving gear 29 is movably connected to the fixed frame 31. A drive device 30 is installed on the fixed frame 31. The drive device 30 is existing technology and includes equipment such as a motor and related accessories. The drive device 30 drives the driving gear 29 to rotate, thereby driving the driven gear 28 to rotate.

[0049] Two movable electrodes 27 are connected to the positive and negative terminals of an external power supply, respectively. When the drive device drives the driven gear 28 and the movable electrode 27 to rotate together, in the initial stage of rotation, the fixed electrode 24 and the movable electrode 27 remain connected. At this time, the electromagnet 23 is always in a closed state. The repulsive force generated keeps the air vent 2 and the air vent 3 sealed. When the movable electrode 27 rotates to a certain angle, the connection between the fixed electrode 24 and the movable electrode 27 changes, that is, the direction of the current in the electromagnet 23 changes, that is, the direction of the magnetic poles generated by the electromagnet 23 changes. This causes the magnetic poles of the opposite surfaces of the electromagnet 23 and the magnetic block 26 to be different, resulting in a magnetic attraction. This causes the two driven gears 28 to move to the outside of the sealing sleeve 16 through the limiting support rod 19 until the air vent 17 is completely exposed, connecting the inside of the outer shell 1 with the external environment through the air vent 2 and the air vent 3.

[0050] When the heat-conducting plate 9 is attached to the surface of the main unit 6 and the main unit 6 is preheating, the sealing plug 18 is in a sealed state against the air vent 1 2 and air vent 2 3. In the initial stage of preheating, the gas inside the outer shell 1 still carries some moisture. During the gradual preheating process of the main unit 6, condensation may still occur. At this time, the circuit of the electromagnet 23 is disconnected, and the top sealing plug 18 falls under the action of gravity. The inside of the outer shell 1 is connected to the external environment through the top air vent 3 17. The bottom is still in a sealed state. At the same time, the fan 22 rotates in the opposite direction, which can blow the gas inside the outer shell 1 out of the outer shell 1, so that the gas inside the outer shell 1 gradually decreases, which can further reduce the possibility of condensation that may occur during the preheating of the main unit 6. After the top air vent 3 17 has been open for a period of time, the circuit of the electromagnet 23 is connected. The magnetism generated by the electromagnet 23 and the repulsive force generated by the magnetic block 26 cause the top sealing plug 18 to move up to abut against the top wall of the outer shell 1, and the inside of the outer shell 1 remains sealed.

[0051] Heating component 10 and electromagnet 12 are electrically connected to movable electrode 27 via wires. Heating component 10, electromagnet 12 and electromagnet 23 are connected in parallel. Each electrical device is connected in series with a switch to individually control the opening and closing of heating component 10, electromagnet 12 and electromagnet 23.
