Description

Technical Field

[0001] The invention belongs to the technical field of network cabinets, and in particular relates to a network cabinet for achieving heat dissipation. Background Art

[0002] A network cabinet is a device that provides an appropriate environment and safety protection for the normal operation of electronic equipment. Multiple network devices are arranged layer by layer from top to bottom in the network cabinet, and there is a certain gap between adjacent network devices. During the operation of network devices, a certain amount of heat will be generated inside the network cabinet, so a heat dissipation device needs to be set up to dissipate heat and cool it down. During the cooling process, the cool air inside the computer room is generally used for cooling;

[0003] At present, a large number of network cabinets or control cabinets with heat dissipation devices are disclosed in existing patents, such as CN221151856U, CN218388488U, CN217936227U, CN216253454 U, etc. However, most of the heat dissipation devices are installed on the cabinet. When the heat dissipation device is installed on the front and rear sides of the cabinet, the cold air entering from the front side will directly pass through the gap between adjacent network devices, resulting in poor heat dissipation effect; when the heat dissipation device is installed at the bottom of the cabinet, the cold air entering from the bottom will only dissipate the bottom of the network device located at the lower layer, and the heat dissipation effect of the upper network device is obviously very poor;

[0004] At the same time, in the prior art, there are many network cabinets that have been installed, but the heat dissipation effect is relatively poor. If fans are installed on the cabinet for heat dissipation, it will increase additional costs and require the entire cabinet to be disassembled. Moreover, the network room is generally a cluster with multiple network cabinets. It is time-consuming and laborious for the on-duty personnel to check the operating status of the network cabinets one by one. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention proposes a network cabinet for achieving heat dissipation to overcome the above problems existing in the prior art.

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

[0007] A network cabinet for heat dissipation includes a cabinet body, a front cabinet door, a rear cabinet door, a heat dissipation component, and a temperature sensor; the rear cabinet door is installed at the rear of the cabinet body by hinge rotation, and the rear cabinet door is a porous mesh structure to achieve heat dissipation; the top of the front cabinet door is sealed but the bottom is not sealed, the heat dissipation component is connected and fixedly installed at the bottom of the inner side of the front cabinet door, and an air inlet is arranged on the ground opposite to the bottom of the front cabinet door; the heat dissipation component includes a heat dissipation housing with an air inlet hole and a heat dissipation fan; the underground cold air brought by the machine room flows in from the air inlet hole, and the air inlet temperature of the heat dissipation fan is the temperature of the underground cold air, which can achieve rapid cooling of the network cabinet. That is, an air inlet is arranged on the ground directly below the front cabinet door, and then the heat dissipation component is arranged so that the underground cold air brought by the machine room can flow into the cabinet body from the hole, and then the heat is dissipated from the front end of the network equipment to the rear, and the air inlet temperature of the heat dissipation component is the temperature of the underground cold air, which can achieve rapid cooling of the network cabinet.

[0008] As a further technical solution, network equipment is arranged in the cabinet, and the temperature sensor is arranged at the front end or the rear end of each network equipment.

[0009] As a further technical solution, an electric door opener or a combined door opening device of an electromagnetic lock and a cabinet door rebounder is also provided on the cabinet body.

[0010] As a further technical solution, an electric door opener disassembly opening needs to be opened on the top of the front cabinet door, and the electric door opener disassembly opening cooperates with the cover plate.

[0011] As a further technical solution, the front cabinet door may be semicircular, semi-elliptical, triangular or trapezoidal.

[0012] As a further technical solution, wind shielding plates are placed on both the left and right sides and the upper and lower sides of the network device.

[0013] As a further technical solution, the heat dissipation assembly consists of a heat dissipation shell and a heat dissipation fan. The heat dissipation shell is fixedly installed on the inner bottom of the front cabinet door by bolt connection, and the heat dissipation fan is fixed to the heat dissipation shell by bolt connection.

[0014] As a further technical solution, the heat dissipation assembly is composed of a heat dissipation shell and a heat dissipation fan. The heat dissipation shell is a fast board, which can be directly fixed on the bottom inside the front cabinet door by welding or bolting. The heat dissipation fan is fixed to the heat dissipation shell by bolting; or the heat dissipation shell and the cabinet door are integrally formed.

[0015] As a further technical solution, a control unit is also included, the temperature sensor is connected to the input end of the control unit, and the control unit controls the heat dissipation component.

[0016] As a further technical solution, the control unit is also connected to the computer room monitoring platform for communication; a touch screen and buttons are provided on the front cabinet door.

[0017] The present invention provides an intelligent temperature control system, the working process of which is as follows: firstly, an upper limit value and a lower limit value of the temperature are set by a program, and when the system is operating normally, each temperature sensor starts to detect the temperature of the corresponding network device and transmits it back to the control unit for processing; when the temperature value detected by a certain temperature sensor is greater than the upper limit value of the set temperature, the control unit automatically outputs a signal to increase the rotation speed of the cooling fan, accelerates the circulation of cold air to achieve a rapid cooling effect; when the temperature detected by all the temperature sensors is lower than the lower limit value of the set temperature, the control unit outputs a signal to stop the cooling fan, and utilizes the natural convection of the air to circulate the cold air; when the temperature detected by all the temperature sensors is between the set lower limit value and the upper limit value, the cooling fan is infinitely regulated according to the temperature difference to achieve energy-saving control;

[0018] Furthermore, the present invention provides a remote monitoring system, which connects the control unit of each network cabinet to the online platform of the host computer through the 485 protocol or other communication protocols. The host computer can monitor in real time whether the operating status of each network cabinet is normal, and can realize a one-key door opening function to open the front cabinet doors of all network cabinets to ensure fire safety.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) The solution of installing a fan for heat dissipation adopted by the present invention does not change the main structure of the cabinet body, but only changes the structure of the front cabinet door. While achieving heat dissipation and cooling, it also effectively reduces the cost. At the same time, the present invention changes the shape of the front cabinet door and sets the heat dissipation component at the bottom of the front cabinet door. Then, the gap between the bottom of the front cabinet door and the ground prevents the front cabinet door from rubbing against the ground. The gap is sealed with a windshield strip to prevent air leakage. An air inlet is set on the ground directly below the front cabinet door. The cold air on the floor of the computer room will enter the network cabinet through the heat dissipation component at the bottom of the front cabinet door, and then flow from bottom to top, starting from the front end surface of each network device for cooling, and then flow backward along the network device body to achieve heat dissipation of the network device. Among them, since the upper and lower gaps between the network devices have been filled with windshield partitions, the cold air can only flow backward through the network device body, thereby enhancing the cooling effect.

[0021] (2) The present invention adopts an electric door opener or an electromagnetic lock + a cabinet door rebounder to replace the traditional manual door opening. When a fire hazard occurs, all front cabinet doors can be opened with one button, which saves time and meets fire protection requirements. In addition, the front cabinet doors can be opened through the inspection port during a power outage.

[0022] (3) The heat dissipation components are installed above the ground to meet fire protection requirements, and the air intake of the heat dissipation fan is underground cold air, which is blown into the interior of the network cabinet and directly passes through the network equipment under the blocking effect of the windshield baffle to achieve rapid cooling;

[0023] (4) The intelligent temperature control system used in the present invention can detect the temperature inside the network cabinet in real time. When the temperature is too high, it automatically increases the speed of the cooling fan to speed up air convection. When the temperature is low, it reduces or stops the fan to achieve energy saving.

[0024] (5) The remote monitoring system adopted by the present invention can monitor all network cabinets in the computer room, which can effectively avoid the on-duty personnel from inspecting each cabinet one by one, thereby improving efficiency and reducing labor intensity.

[0036] The present embodiment discloses a network cabinet for achieving heat dissipation, comprising a cabinet body, a front cabinet door, a rear cabinet door, a heat dissipation component, and a temperature sensor; the rear cabinet door is rotatably installed at the rear of the cabinet body through a hinge, and the rear cabinet door is a porous mesh structure to achieve heat dissipation; the top of the front cabinet door is sealed but the bottom is not sealed, the heat dissipation component is connected and fixedly installed at the bottom inside the front cabinet door, and an air inlet is provided on the ground opposite to the bottom of the front cabinet door; the heat dissipation component comprises a heat dissipation housing with an air inlet hole and a heat dissipation fan; the underground cold air of the computer room flows in from the air inlet hole, and the air inlet temperature of the heat dissipation fan is the temperature of the underground cold air, which can achieve rapid cooling of the network cabinet. That is, an air inlet is set on the ground just below the front cabinet door, and then cooperate with the heat dissipation component to allow the underground cold air in the computer room to flow into the cabinet from the hole, and then dissipate heat from the front face of the network equipment to the rear. Since the top, bottom, left and right of the network equipment have been blocked by windshield baffles, the cold air can only flow from the network equipment body. The air inlet temperature of the heat dissipation component is the temperature of the underground cold air, which can achieve rapid cooling of the network equipment inside the network cabinet.

[0037] like Figure 1-Figure 8As shown, the present embodiment discloses a network cabinet for achieving heat dissipation, including a cabinet body 2, a front cabinet door 5, a rear cabinet door 1, a cover plate 4, an electric door opener 3, a heat dissipation component 8, a temperature sensor, a control unit 9, a touch screen 6, and a button 7; the cabinet body 2 is placed on the ground, and is composed of a front mounting column 24, a middle mounting column 23, a rear mounting column 21, an L-shaped device bracket 25 and a network device 22; the front mounting column 24, the middle mounting column 23, and the rear mounting column 21 are symmetrically fixedly installed on both sides of the cabinet body 2, and the front mounting column 24, the middle mounting column 23, and the rear mounting column 21 have the same structure, and rectangular small holes are evenly distributed thereon; the L-shaped device bracket 25 has three circular holes, and the positions of the circular holes correspond to the rectangular small holes of the front mounting column 24, the middle mounting column 23, and the rear mounting column 21, respectively, and the L-shaped device bracket 25 is fixed by bolt connection, and the L-shaped device bracket 25 is installed symmetrically on the left and right, and the height position can be adjusted arbitrarily;

[0038] The network device 22 is placed on the upper surface of the L-shaped device bracket 25 to ensure that the network device 22 can work safely and normally; Figure 1 In the figure, only two installation scenarios of network devices 22 are given. In fact, in the prior art, multiple network devices 22 are arranged layer by layer from top to bottom; and wind shielding baffles 26 are placed on the left and right sides and the upper and lower sides of the network device 22 to facilitate cold air to directly pass through the network device, thereby achieving a better cooling effect; wherein, the material of the wind shielding baffle 26 can be a PVC baffle.

[0039] The rear cabinet door 1 is rotatably installed at the rear of the cabinet body 2 through a hinge, and the rear cabinet door 1 is a porous mesh structure, which is convenient for the discharge of hot air inside the cabinet body 2;

[0040] Furthermore, the present embodiment mainly improves the front cabinet door 5. Specifically, the front cabinet door 5 is rotatably installed in front of the cabinet body 2 by means of hinges. The front cabinet door 5 can be in a semicircular, semi-elliptical, triangular, trapezoidal or other shapes to ensure that a cavity can be reserved inside for air circulation and to provide an installation position for the control unit 9 and the heat dissipation component 8. The top of the front cabinet door 5 is sealed but the bottom is not sealed. A heat dissipation component is installed inside the bottom inner side of the front cabinet door 5. The cold air on the floor of the computer room will enter the network cabinet through the heat dissipation component at the bottom of the front cabinet door 5, and then flow from bottom to top, starting to cool from the front end face of each network device, and then flowing backward along the network device body to achieve heat dissipation of the network equipment. Among them, since the upper and lower gaps between the network equipment have been attached by windshield partitions, the cold air can only flow backward through the network device body, so the cooling effect is enhanced.

[0041] As a technical solution of the first embodiment, the heat dissipation assembly 8 is composed of a heat dissipation shell 81 and a heat dissipation fan 82. The heat dissipation shell 81 is fixedly installed on the inner bottom of the front cabinet door 5 by bolt connection. The heat dissipation fan 82 is fixed on the heat dissipation shell 81 by bolt connection. The heat dissipation fan 82 can be arranged according to the actual situation, and there can be one or more heat dissipation fans; the height of the heat dissipation assembly 8 from the ground should be as small as possible, but it cannot be in direct contact with the ground, otherwise when the front cabinet door 5 is opened, it will rub against the ground and cause wear on the heat dissipation shell 81;

[0042] As a technical solution of the second embodiment, the heat dissipation assembly 8 is composed of a heat dissipation housing 81 and a heat dissipation fan 82. The heat dissipation housing 81 is a plate and can be directly fixed on the inner bottom of the front cabinet door 5 by welding. The heat dissipation fan 82 is fixed to the heat dissipation housing 81 by bolts. The heat dissipation fan 82 can be arranged according to actual conditions, and there can be one or more. The height of the heat dissipation assembly 8 from the ground should be as small as possible, but it cannot be directly in contact with the ground.

[0043] As a technical solution of another embodiment, the front cabinet door 5 also needs to open a hole to provide a mounting position for the touch screen 6 and the button 7;

[0044] As a technical solution of another embodiment, a rectangular opening is further provided on the top of the front cabinet door 5 for disassembling the electric door opener 3 in case of power failure, so as to ensure that the front cabinet door 5 can be opened normally. The cover plate 4 is placed at the top opening position of the front cabinet door 5, and its size is slightly larger than the rectangular opening, so as to ensure that dust and other impurities do not fall into the interior of the front cabinet door 5.

[0045] Specifically, as a technical solution for implementation mode 1, the electric door opener 3 is installed on the cabinet 2, and the electric door opener 3 is composed of a housing 32, a DC motor, an L-shaped mounting plate 31, a rocker arm 33, a roller 35 and a slide groove 34; the DC motor is fixedly installed inside the housing 32 by screws, and the output shaft of the DC motor is connected to the rocker arm 33. When the DC motor rotates forward and reverse, it will synchronously drive the rocker arm 33 to rotate forward and reverse; there are two L-shaped mounting plates 31, which are symmetrically arranged on both sides of the housing 32 to facilitate the installation of the electric door opener 3; the roller 35 is installed at the end of the rocker arm 33 and can roll on a fixed axis to reduce friction; the slide groove 34 is installed on the inner side of the front cabinet door 5 by screws, and the roller 35 is arranged inside the slide groove 34. When the rocker arm 33 rotates, the position of the roller 35 in the slide groove 34 can be changed, thereby realizing the function of opening the door;

[0046] As a technical solution for the second implementation mode, the electric door opener 3 is installed on the cabinet 2. The electric door opener 3 is composed of a suction plate 37, an electromagnet 38 and a rebounder 39. The suction plate 37 is fixedly installed on the front cabinet door 5, and the electromagnet 38 and the rebounder 39 are installed inside the cabinet 2. When the front cabinet door 5 needs to be closed, the electromagnet 38 is energized and attracted to the suction plate 37. At this time, the spring inside the rebounder 39 is compressed by the front cabinet door 5; when the front cabinet door 5 needs to be opened, the electromagnet 38 is powered off, and there is no magnetic force between the electromagnet 38 and the suction plate 37, and the door is automatically opened under the action of the spring force of the rebounder 39, thereby realizing the function of opening the door;

[0047] An air inlet hole of a corresponding shape to the front cabinet door 5 is cut out on the floor directly below the front cabinet door 5. The underground cold air in the computer room can flow out from the air inlet hole and enter the cabinet. The air inlet temperature of the cooling fan 82 is the temperature of the underground cold air, which can achieve rapid cooling of the network cabinet; the cold air on the floor of the computer room will enter the network cabinet through the heat dissipation component at the bottom of the front cabinet door 5, and then flow from bottom to top, starting to cool from the front end face of each network device, and then flow backward along the network device body to achieve heat dissipation of the network equipment. Among them, since the upper and lower gaps between the network equipment have been blocked by the windshield partition, the cold air can only flow backward through the network equipment body, so the cooling effect is enhanced.

[0048] Furthermore, in order to realize the temperature control of the network device 22, the present embodiment further provides a temperature sensor 10 and a control unit 9. There are multiple temperature sensors, which are arranged at the front end or the back end of each network device 22, and are used to detect the inlet temperature or outlet temperature of each network device 22 in real time; the control unit 9 is composed of a single-chip microcomputer or a programmable logic controller, which can realize the input and output of signals and the conversion of analog quantities to digital quantities;

[0049] The electric door opener 3, the touch screen 6, the button 7, and the cooling fan 81 are all connected to the control unit 9, and the control unit 9 processes the temperature detected by the temperature sensor and directly displays it on the touch screen 6; by programming the control unit 9, the touch screen 6 can perform human-computer interaction, and can switch between automatic mode and manual mode. In the manual mode, the function of manually adjusting the speed of the cooling fan 82 can be realized;

[0050] The present invention provides an intelligent temperature control system, and its working process is as follows: firstly, the upper limit and lower limit of the temperature are set by a program, and when the system is operating normally, each temperature sensor starts to detect the temperature of the corresponding network device 22, and transmits it back to the control unit 9 for processing; when the temperature value detected by a certain temperature sensor is greater than the upper limit of the set temperature, the control unit 9 automatically outputs a signal to increase the rotation speed of the cooling fan 82, and accelerates the circulation of cold air to achieve the effect of rapid cooling; when the temperature detected by all temperature sensors is lower than the lower limit of the set temperature, the control unit 9 outputs a signal to stop the cooling fan 82, and utilizes the natural convection of air to circulate the cold air; when the temperature detected by all temperature sensors is between the set lower limit and upper limit, the cooling fan 82 runs at a low speed to achieve energy-saving control;

[0051] The invention provides a remote monitoring system, which connects the control unit 9 of each network cabinet to the online platform of the host computer through the 485 protocol or other communication protocols. The host computer can monitor in real time whether the operating status of each network cabinet is normal, and can realize a one-key door opening function to open the front cabinet doors of all network cabinets to ensure fire safety.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
