Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial control computer technology, and more specifically, it relates to a moisture-proof industrial control computer. Background Technology
[0002] Industrial control computers (ICCs) are highly reliable computers designed specifically for industrial environments. They are widely used in smart manufacturing, energy, transportation, and other fields, responsible for equipment control, data acquisition, and real-time monitoring. Due to the complex nature of industrial environments, which may present challenges such as high humidity, condensation, and dust, ICCs need to be moisture-proof. Humid environments can lead to short circuits, component corrosion, or signal interference, affecting stable equipment operation and even causing malfunctions.
[0003] Traditional methods for preventing moisture in industrial PCs involve installing moisture-absorbing drying bags or sheets at the air intake to dry the airflow entering the PC.
[0004] However, desiccant packs and desiccant sheets are small in size and have limited moisture absorption capacity. Especially in relatively humid workshops, their moisture absorption and drying effect on airflow is minimal. In order to ensure the internal dryness of the industrial control computer, it is necessary to frequently replace desiccant sheets and desiccant packs, resulting in poor moisture protection. For example, a moisture-proof industrial control computer is provided in Chinese patent document CN219392597U.
[0005] A moisture-proof industrial control computer disclosed in Chinese patent document CN222813097U uses a filter and heating wire to heat the airflow and evaporate the moisture to achieve moisture prevention inside the industrial control computer. However, the above method will result in a high internal temperature of the industrial control computer. During the operation of the industrial control computer, the internal electrical components need to dissipate heat. Thus, using high temperature to evaporate the moisture will cause the internal electrical components of the industrial control computer to operate at a continuous high temperature, affecting the service life and performance. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] In view of the problems existing in the prior art, this utility model provides a moisture-proof industrial control computer to solve the technical problem mentioned in the background art that the moisture-proof effect of the existing moisture-proof industrial control computer is poor.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A moisture-proof industrial control computer includes a base, on which a heat-conducting mounting base is provided, and an electrical component assembly is mounted on the heat-conducting mounting base. A protective cover is provided above the base, and heat dissipation fins are provided on the outer side of the protective cover. A first cooling fan is provided above the heat dissipation fins. A back plate is provided on one side of the protective cover and the base. An interface assembly is sealed on the back plate, and the base, protective cover, and back plate form a protective zone through a sealed fit. A guide shroud is provided at the top inside the protective cover. Air inlet pipes are provided at both ends of the guide shroud, and an air outlet pipe is provided in the middle. A second cooling fan is provided inside the air outlet pipe, and the air outlet pipe is oriented towards the electrical component assembly.
[0011] The present invention is further provided that the air outlet end of the air outlet pipe is provided with a blowing fine mesh. The blowing fine mesh can prevent the airflow from the air outlet pipe from being too strong and causing the airflow to erode the electrical components over a long period of time, thereby improving heat dissipation and protection.
[0012] The present invention is further configured such that a plurality of heat exchange columns are provided at the top of the inner side of the protective cover, and the heat exchange columns extend into the interior of the guide shroud. Under the driving action of the second heat dissipation fan, the airflow inside the protective zone is driven to achieve internal circulation, so that the airflow can be blown out from the air outlet and swept on the surface of the electrical component group, thereby blowing away the heat on the surface of the electrical component group and improving the heat dissipation effect. Under the driving action of the second heat dissipation fan, the air inlet pipes at both ends of the guide shroud are in a negative pressure state, so that the airflow in the protective zone will re-enter the guide shroud through the air inlet pipe and flow along the guide shroud, and then circulate and be blown out from the air outlet. During this process, the airflow will come into contact with the heat exchange columns to achieve heat exchange. Since the heat exchange columns are directly connected to the external heat dissipation fins through the protective cover, heat can be quickly transferred to the heat dissipation fins to achieve heat dissipation and enhance the heat dissipation effect on the surface of the electrical component group.
[0013] The present invention is further provided that the bottom end of the protective cover is provided with mounting edges, and mounting holes are provided on the mounting edges. The cooperation between the mounting edges and the mounting holes facilitates the installation and fixation of the industrial control computer on the external mounting surface.
[0014] The present invention is further configured such that an installation port is provided on the back plate, and a sealing cover is detachably provided at the installation port by bolts. The inner side of the sealing cover extends into the protected area through the installation port and is provided with a moisture-absorbing component.
[0015] The present invention is further configured such that the moisture-absorbing component includes a locking frame, which is disposed inside the sealing cover. The locking frame has a locking groove, and a drying sheet is disposed in the locking groove. The drying sheet is inserted into the locking groove to be fixed on the locking frame. With the cooperation of the sealing cover, the locking frame extends into the protective cover from the installation opening. The sealing cover is then fixed to the sealing gasket structure by bolts, and stably and securely installed at the installation opening to achieve a seal at the installation opening. This allows the drying sheet to be stably installed in the protected area to absorb moisture within the protected area. As an auxiliary means, the drying sheet can address the decrease in the sealing performance of the protected area caused by the aging of the sealing gasket and prevent internal moisture absorption.
[0016] This invention is further configured such that the side of the heat-conducting mounting base is provided with an insertion strip, and the inner wall of the protective cover is provided with an insertion groove. The insertion strip and the insertion groove are interlocked. When the protective cover is fastened to the base, the insertion groove and the insertion strip are interlocked, thereby achieving precise positioning of the protective cover during installation. At the same time, during the use of the industrial control computer, the CPU, GPU, power module, hard disk, motherboard chipset, memory, expansion card, voltage regulator and other related electrical components in the electrical component group will generate heat during use. This invention mounts the electrical component group on the heat-conducting mounting base, which allows the heat generated during operation to be quickly conducted outward through the heat-conducting mounting base. Through the cooperation of the insertion groove and the insertion strip, the heat-conducting mounting base and the insertion strip work together to quickly transfer the heat to the protective cover, and the cooperation of the protective cover and the heat dissipation fins achieves rapid heat dissipation, enhancing the cooling effect of the electrical component group during operation.
[0017] The present invention is further configured such that a connecting edge is provided on the side of the protective cover near the back plate, and the back plate is locked and fixed between the connecting edge and the base by bolts. The setting of the connecting edge can realize the installation limit of the back plate, and the bolt fixing facilitates the disassembly of the back plate. The back plate, the connecting edge and the base are all sealed by sealing gaskets.
[0018] (III) Beneficial Effects
[0019] Compared with the prior art, this utility model provides a moisture-proof industrial control computer, which has the following beneficial effects:
[0020] 1. This utility model forms a protective zone through the sealed cooperation of the base, protective cover, and back plate, completely isolating the electrical component assembly internally and effectively preventing the intrusion of external moisture. Compared with traditional moisture-proof methods (such as desiccant packs or heating evaporation), this design uses physical isolation, fundamentally preventing humid air from contacting the electrical components and significantly improving the moisture-proof effect. The desiccant pack within the protective zone serves as an auxiliary moisture absorption method, addressing unexpected situations such as aging of the sealing structure, providing double protection to ensure the long-term stable operation of the industrial control computer in humid environments. In addition, the interface components on the back plate are sealed, further eliminating the possibility of moisture seeping in through interface gaps, resulting in overall moisture-proof performance superior to existing technologies.
[0021] 2. This utility model, while providing a sealed and moisture-proof environment, ensures the heat dissipation needs of electrical components through multiple heat dissipation designs. The heat-conducting mounting base and the protective cover are tightly connected via interlocking strips and slots, rapidly transferring the heat generated by the electrical components to the heat dissipation fins outside the protective cover, in conjunction with the forced convection cooling by the first cooling fan. An internally located second cooling fan drives airflow circulation, precisely directing the airflow towards the surface of the electrical components through a guide shroud and exhaust duct. Combined with the heat exchange column and the heat-conducting structure of the top wall of the protective cover, heat is efficiently transferred to the external heat dissipation fins. This coordinated internal and external heat dissipation method avoids the internal high-temperature problem caused by heated airflow in traditional moisture-proof industrial control computers, and also solves the problem of low heat dissipation efficiency in sealed environments.
[0022] 3. This utility model adopts a modular design, facilitating installation and maintenance. The protective cover and base are quickly positioned via a mating strip and a mating slot. The back plate is detachably installed using bolts, and the sealing cover and back plate are detachably sealed using bolts, simplifying the assembly process. The drying disc is installed via a snap-fit bracket; replacement only requires removing the sealing cover without damaging the overall sealing structure. Furthermore, the design of the mounting edge and mounting holes facilitates the fixing of the industrial control computer in various scenarios. This modular structure not only reduces production complexity but also facilitates regular maintenance by users, such as replacing the drying disc or cleaning the internal components, extending the equipment's service life.

[0032] Please see Figures 1-5 A moisture-proof industrial control computer includes a base 1, a heat-conducting mounting base 2 on the base 1, an electrical component assembly mounted on the heat-conducting mounting base 2, a protective cover 3 on the top of the base 1, heat dissipation fins 4 on the outer side of the protective cover 3, a first cooling fan 5 on the top of the heat dissipation fins 4, a back plate 6 on one side of the protective cover 3 and the base 1, an interface assembly sealed on the back plate 6, and a protective zone 7 formed by the sealed cooperation between the base 1, the protective cover 3 and the back plate 6, a guide shroud 8 at the top inside the protective cover 3, air inlet pipes 9 at both ends of the guide shroud 8, and an air outlet pipe 10 in the middle, a second cooling fan 11 inside the air outlet pipe 10, and the air outlet pipe 10 facing the electrical component assembly.
[0033] Please see Figures 1-5 As one implementation of the air outlet duct 10: an air-blowing fine mesh 12 is provided at the air outlet end of the air outlet duct 10. The air-blowing fine mesh 12 can prevent the airflow from the air outlet duct 10 from being too strong and causing airflow erosion of electrical components due to long-term accumulation, thereby improving heat dissipation and protection.
[0034] Please see Figures 1-5 As one implementation of the protective cover 3: multiple heat exchange columns 13 are provided at the top of the inner part of the protective cover 3. The heat exchange columns 13 extend into the interior of the guide shroud 8. Under the driving action of the second heat dissipation fan 11, the airflow inside the protective zone 7 will be driven to achieve internal circulation, so that the airflow can be blown out from the air outlet 10 and swept on the surface of the electrical component group, thereby blowing away the heat on the surface of the electrical component group and improving the heat dissipation effect. Under the driving action of the second heat dissipation fan 11, the air inlet pipes 9 at both ends of the guide shroud 8 will be in a negative pressure state, so the airflow in the protective zone 7 will enter the guide shroud 8 again through the air inlet pipes 9 and flow along the guide shroud 8, and then circulate and be blown out from the air outlet 10. During this process, the airflow will come into contact with the heat exchange columns 13 to achieve heat exchange. Since the heat exchange columns 13 are directly connected to the external heat dissipation fins 4 through the protective cover 3, the heat can be quickly transferred to the heat dissipation fins 4 to achieve heat dissipation and enhance the heat dissipation effect on the surface of the electrical component group.
[0035] Please see Figures 1-5 As one embodiment of the protective cover 3: the bottom end of the protective cover 3 is provided with mounting edges 14, and mounting holes 15 are provided on the mounting edges 14. The cooperation between the mounting edges 14 and the mounting holes 15 facilitates the installation and fixation of the industrial control computer on the external mounting surface.
[0036] Please see Figures 1-5 As one embodiment of the back panel 6: the back panel 6 has an installation port 16, and a sealing cover 17 is detachably installed at the installation port 16 by bolts. The inner side of the sealing cover 17 extends into the protected area 7 through the installation port 16 and is provided with a moisture-absorbing component.
[0037] Please see Figures 1-5 As one implementation of the moisture-absorbing component: the moisture-absorbing component includes a locking frame 18, which is disposed inside the sealing cover 17. The locking frame 18 has a locking groove 19, and a drying sheet 20 is disposed in the locking groove 19. The drying sheet 20 is inserted into the locking groove 19 to fix it on the locking frame 18. With the cooperation of the sealing cover 17, the locking frame 18 extends into the protective cover 3 from the installation port 16. The sealing cover 17 is then fixedly installed at the installation port 16 by bolts and the sealing gasket structure, achieving a seal at the installation port 16. This allows the drying sheet 20 to be stably installed in the protected area 7 to absorb moisture in the protected area 7. The drying sheet 20 serves as an auxiliary means to prevent the interior from becoming damp when the sealing effect in the protected area 7 deteriorates due to the aging of the sealing gaskets between some structures.
[0038] Please see Figures 1-5As one embodiment of the heat-conducting mounting base 2: the heat-conducting mounting base 2 is provided with a mating strip 21 on its side, and a mating groove 22 is provided on the inner wall of the protective cover 3. The mating strip 21 and the mating groove 22 are interlocked. When the protective cover 3 is fastened to the base 1, the mating groove 22 and the mating strip 21 are interlocked, thereby achieving precise positioning of the protective cover 3 during installation. At the same time, during the use of the industrial control computer, the CPU, GPU, power module, hard disk, motherboard chipset, memory, expansion card, voltage regulator and other related electrical components in the electrical component group will generate heat during use. This utility model installs the electrical component group on the heat-conducting mounting base 2, which allows the heat generated during operation to be quickly conducted outward through the heat-conducting mounting base 2. Through the cooperation of the mating groove 22 and the mating strip 21, the heat-conducting mounting base 2 and the mating strip 21 cooperate to quickly transfer the heat to the protective cover 3, and the protective cover 3 cooperates with the heat dissipation fins 4 to achieve rapid heat dissipation, thereby enhancing the cooling effect of the electrical component group during operation.
[0039] Please see Figures 1-5 As one embodiment of the protective cover 3: the protective cover 3 is provided with a connecting edge 23 on the side near the back plate 6. The back plate 6 is locked and fixed between the connecting edge 23 and the base 1 by bolts. The setting of the connecting edge 23 can realize the installation limit of the back plate 6. The bolt fixing facilitates the disassembly of the back plate 6. The back plate 6, the connecting edge 23 and the base 1 are all sealed by sealing gaskets.
[0040] In summary:
[0041] This utility model sets up a base 1, a protective cover 3, and a back plate 6, and the base 1, the protective cover 3, and the back plate 6 cooperate with each other to form a sealed protective zone 7. The electrical components in the industrial control computer are installed in this protective zone 7, which can effectively isolate them from the outside world, thereby effectively preventing moisture in the external processing workshop from entering the interior of the industrial control computer and improving the moisture-proof effect of the industrial control computer during use.
[0042] During installation, the electrical component assembly is first installed on the heat-conducting mounting base 2 on the base 1. Then, the protective cover 3 is fastened to the base 1 with the cooperation of the insertion strip 21 and the insertion groove 22. One side of the protective cover 3 is closed, and the other side cooperates with the back plate 6 to achieve the sealing of the protective area 7.
[0043] The base 1 and the protective cover 3 can be fixed together with bolts. Then, the corresponding interfaces in the interface assembly on the back plate 6 are connected to the corresponding electrical components in the electrical component group. After the wiring is completed, the back plate 6 is sealed and installed on the protective cover 3 and the base 1 by the cooperation of bolts and sealing gaskets, etc., so as to close the protective zone 7.
[0044] When in use, the first cooling fan 5 and the second cooling fan 11 are turned on. During use, the heat generated at the bottom of the electrical component group will be quickly transferred to the insertion strip 21 through the heat-conducting mounting base 2, and then transferred to the protective cover 3 through the insertion strip 21. Then, the heat is quickly dissipated through the heat dissipation fins 4 on the surface of the protective cover 3.
[0045] The use of the first cooling fan 5 can accelerate the heat dissipation effect of the cooling fins 4;
[0046] At the same time, the protective cover 3 itself also has the effect of conducting and dissipating heat, and can also quickly transfer the heat generated by the electrical components during operation to the outside through the air diversion in the protective zone 7 to achieve heat dissipation;
[0047] During operation, the second cooling fan 11 is started. Driven by the second cooling fan 11, the airflow inside the protection zone 7 is driven to achieve internal circulation, so that the airflow can be blown out from the air outlet 10 and blown on the surface of the electrical component group, thereby blowing away the heat on the surface of the electrical component group and improving the heat dissipation effect of the surface of the electrical component group.
[0048] Driven by the second cooling fan 11, the air inlet pipes 9 at both ends of the air guide shroud 8 will be in a negative pressure state. As a result, the airflow in the protected area 7 will enter the air guide shroud 8 again through the air inlet pipe 9 after passing through the electrical component group, and will flow along the air guide shroud 8, and then be blown out from the air outlet pipe 10 in a cycle.
[0049] During this process, the airflow will come into full contact with the inner wall of the protective cover 3, and the airflow flowing inside the guide shroud 8 will come into contact with the heat exchange column 13 for heat exchange, and at the same time come into contact with the top wall of the protective cover 3 for heat exchange.
[0050] Since the heat exchange column 13 is directly connected to the external heat dissipation fins 4 through the protective cover 3, heat can be quickly transferred to the heat dissipation fins 4 to achieve heat dissipation and enhance the heat dissipation effect on the surface of the electrical component group.
[0051] This invention also incorporates a drying sheet 20 within the protected area 7 via a detachable sealing and insertion mechanism. This effectively prevents moisture buildup inside the protected area 7 when the seal fails.
[0052] In this utility model, the sealing connection between related components can be achieved by a sealing gasket. Achieving a sealing connection by a sealing gasket is a conventional sealing connection method, which should be known to those skilled in the art. This utility model will not elaborate on this.
[0053] To balance the pressure within the protected zone 7, a waterproof and breathable valve can be installed on the protective cover 3;
[0054] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although the embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
