Description

Technical Field

[0001] This invention relates to the field of electrical cabinet equipment technology, and particularly to an electrical cabinet door. Background Technology

[0002] Currently, electrical cabinet doors typically integrate filters to remove impurities from external cold air. However, these filters have limited filtration capacity; even after passing through the filter, some impurities can still be carried directly into the interior of the electrical cabinet, affecting the performance of the electrical components inside.

[0003] In other words, the relevant technology has the problem that the electrical cabinet door has a poor filtration effect on external cold air. Summary of the Invention

[0004] In view of the problems in the prior art, this application proposes an electrical cabinet door that solves the problem of poor filtration effect of the electrical cabinet door on external cold air.

[0005] The present invention relates to an electrical cabinet door, which is rotatably mounted on an electrical cabinet. The electrical cabinet door includes: an inner door panel assembly with an air outlet communicating with the inner cavity of the electrical cabinet; an outer door panel mounted on the inner door panel assembly with an air inlet; and an air filter device mounted on the outer door panel, the outer door panel being located between the inner door panel assembly and the air filter device. An airflow buffer layer is provided between the inner door panel assembly and the outer door panel, allowing external cold air to sequentially pass through the air filter device, the air inlet, the airflow buffer layer, and the air outlet to enter the inner cavity of the electrical cabinet, thereby dissipating heat and cooling the electrical components within the electrical cabinet.

[0006] In one embodiment, an airflow buffer layer is fixed to the outer door panel. The airflow buffer layer includes: an inner upper plate; an inner lower plate located below the inner upper plate; a first inner side plate connected to one end of the inner upper plate and one end of the inner lower plate; a second inner side plate connected to the other ends of the inner upper plate and the inner lower plate; and an inner bottom plate with an air outlet, connected to the inner upper plate, inner lower plate, first inner side plate, and second inner side plate. One end of the inner upper plate and one end of the inner lower plate are on the same side, and the other end of the inner upper plate and the other end of the inner lower plate are on the same side. In this embodiment, the inner bottom plate, inner upper plate, inner lower plate, first inner side plate, and second inner side plate are joined together to define a sealed cavity, buffering the airflow and preventing impurities from being directly introduced into the inner cavity of the electrical cabinet. Simultaneously, the sealed cavity collects impurities, thereby enhancing the filtration effect of the electrical cabinet door.

[0007] In one embodiment, the inner lower plate and the inner bottom plate form an angle β, where the value of angle β ranges from 5° to 60°. With this embodiment, impurities within the airflow buffer layer can slide down the inner wall of the inner lower plate to the bottom of the air filter device for discharge through the electrical cabinet door. This prevents impurity accumulation within the airflow buffer layer, ensuring the device's high-efficiency filtration effect and facilitating on-site maintenance and upkeep.

[0008] In one embodiment, the air outlet and the air inlet of the air filter are staggered. This staggered arrangement of the air filter's inlet and outlet helps create a tortuous airflow channel within the airflow buffer layer. External airflow passing through this buffer layer forms vortices, increasing resistance and thus weakening the kinetic energy of rainwater impurities. Simultaneously, the tortuous airflow channel effectively buffers the velocity of impurities entrained in the air, preventing them from keeping up with changes in airflow direction. Furthermore, the greater gravity of these impurities makes them easily separated from the airflow. This, in turn, enhances the filtration effect of the electrical cabinet door.

[0009] In one embodiment, the inner door panel assembly includes: a heat dissipation ventilation duct, at least partially disposed within an airflow buffer layer, the inner cavity of the heat dissipation ventilation duct not communicating with the airflow buffer layer; and an internal circulation fan, communicating with both the inner cavity of the heat dissipation ventilation duct and the inner cavity of the electrical cabinet. This embodiment, with its staggered arrangement of the air filter's inlet and outlet, and the heat dissipation ventilation duct interspersed within the airflow buffer layer, utilizes a unique scientific design to create a tortuous airflow channel. External airflow passing through the heat dissipation ventilation duct forms vortices, increasing resistance and thus weakening the kinetic energy of rainwater impurities. Simultaneously, the tortuous airflow channel effectively buffers the speed of rainwater impurities carried in the air, preventing them from keeping up with the change in airflow direction. Furthermore, the greater gravity of the impurities makes them easily separated from the airflow. As they pass through the airflow buffer layer, they quickly fall onto the inner lower plate under gravity and slide out of the electrical cabinet door, preventing the accumulation of impurities inside the electrical cabinet door and further ensuring efficient filtration and easy maintenance.

[0010] In one embodiment, the inner door panel assembly includes a plurality of heat dissipation and ventilation ducts, which are spaced apart along a first direction and / or extend along a second direction.

[0011] In one embodiment, the inner door panel assembly further includes a fan mounting box, which is fixedly connected to the outer door panel for mounting an internal circulation fan.

[0012] In one embodiment, the inner door panel assembly further includes an inner door frame, on which an airflow buffer layer is embedded. Through this embodiment, the inner door frame, as a structural component, can enhance the overall structural strength of the electrical cabinet door, ensuring it meets strength requirements.

[0013] In one embodiment, the inner door panel assembly further includes a sealing strip disposed on the outer periphery of the inner door frame for sealing the gap between the inner door panel assembly and the outer door panel.

[0014] In one embodiment, the device also includes a door lock disposed on the inner door panel assembly, and / or includes a hook disposed on the outer door panel.

[0015] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0016] The electrical cabinet door provided by this invention has at least the following advantages compared with the prior art:

[0017] The airflow buffer layer provides a buffer zone for airflow, preventing impurities from being directly introduced into the inner cavity of the electrical cabinet. Furthermore, the airflow first collides with the inner wall of the airflow buffer layer, causing any impurities to separate from the airflow and fall to the bottom of the buffer layer under their own gravity. This enhances the filtration effect of the electrical cabinet door. Attached Figure Description

Detailed Implementation

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] It should be noted that the impurities in this application refer to dust, particles, and other impurities in external cold air, as well as various particulate impurities carried by rainwater. The second direction in this application is... Figure 2 The direction perpendicular to the paper surface, i.e. Figure 3 The length direction of the cabinet door of Zhongdian Electric.

[0028] like Figures 1 to 4 As shown, the present invention provides an electrical cabinet door, which is rotatably mounted on an electrical cabinet and includes an inner door panel assembly 10, an outer door panel 20, and an air filter device 40.

[0029] The inner door panel assembly 10 is provided with an air outlet 11, which communicates with the inner cavity of the electrical cabinet. An outer door panel 20 is mounted on the inner door panel assembly 10 and has an air inlet 21. An air filter 40 is mounted on the outer door panel 20, located between the inner door panel assembly 10 and the air filter 40. An airflow buffer layer 30 is provided between the inner door panel assembly 10 and the outer door panel 20, allowing external cold air to sequentially pass through the air filter 40, the air inlet 21, the airflow buffer layer 30, and the air outlet 11 to enter the inner cavity of the electrical cabinet, thereby dissipating heat and cooling the electrical components within the cabinet.

[0030] In the above configuration, the airflow buffer layer 30 provides a buffer zone for airflow, preventing impurities from being directly introduced into the inner cavity of the electrical cabinet. Furthermore, the airflow first collides with the inner wall of the airflow buffer layer 30, causing any impurities to separate from the airflow after impact, and then fall to the bottom of the airflow buffer layer 30 under its own gravity. This enhances the filtration effect of the electrical cabinet door on external cold air.

[0031] It should be noted that the air filter 40 performs initial filtration of the air entering the electrical cabinet door, removing most of the impurities. The remaining small portion of impurities will be carried by the airflow through the air inlet 21 into the airflow buffer layer 30 for secondary filtration. This dual filtration enhances the filtration effect of the electrical cabinet door.

[0032] Specifically, such as Figures 1 to 4 As shown, in one embodiment, the air filtration device 40 employs a ventilation filter.

[0033] It should be noted that ventilation filters are not limited to inertial filters, mesh filters, and louver filters.

[0034] Specifically, such as Figure 3 As shown, in one embodiment, the airflow buffer interlayer 30 is fixed to the outer door panel 20. The airflow buffer interlayer 30 includes an inner upper plate 31, an inner lower plate 32, a first inner side plate 33, a second inner side plate 34, and an inner bottom plate 35.

[0035] The inner lower plate 32 is located below the inner upper plate 31. The first inner side plate 33 is connected to one end of the inner upper plate 31 and one end of the inner lower plate 32. The second inner side plate 34 is connected to the other end of the inner upper plate 31 and the other end of the inner lower plate 32. The inner bottom plate 35 is provided with an air outlet 11 and is connected to the inner upper plate 31, the inner lower plate 32, the first inner side plate 33, and the second inner side plate 34.

[0036] In the above configuration, the inner bottom plate 35 is spliced ​​and connected with the inner upper plate 31, inner lower plate 32, first inner side plate 33, and second inner side plate 34 to form a sealed cavity, which buffers the airflow (the inner cavity of the airflow buffer layer), thereby preventing the airflow from directly carrying impurities into the inner cavity of the electrical cabinet. At the same time, the sealed cavity collects impurities. This enhances the filtration effect of the electrical cabinet door.

[0037] It should be noted that the airflow buffer layer 30 is not necessarily fixed to the outer door panel 20, but can also be fixed to the electrical cabinet.

[0038] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the first inner side plate 33 and the second inner side plate 34 are arranged in parallel and their ends are flush.

[0039] Specifically, such as Figure 3 As shown, in one embodiment, the inner bottom plate 35, the inner upper plate 31, the inner lower plate 32, the first inner side plate 33, and the second inner side plate 34 are all provided with flanges, and the flanges are provided with connecting holes. Correspondingly, the outer door plate 20 is provided with threaded connecting holes. Connecting bolts are passed through the connecting holes and connected to the threaded connecting holes to fix the airflow buffer interlayer 30 to the outer door plate 20.

[0040] Specifically, such as Figure 2 As shown, in one embodiment, the inner lower plate 32 and the inner bottom plate 35 have an included angle β, and the value of the included angle β is in the range of 5°≤β≤60°.

[0041] In the above configuration, impurities within the airflow buffer jacket 30 can slide down the inner wall of the lower inner plate 32 to the bottom of the air filter device 40, so as to be discharged from the electrical cabinet door. This avoids the accumulation of impurities within the airflow buffer jacket 30, thereby ensuring the high-efficiency filtration effect of the device and facilitating on-site maintenance and upkeep.

[0042] It should be noted that the bottom of the air filter device 40 may be provided with an outlet for discharging impurities.

[0043] Specifically, in one embodiment, the inner lower plate 32 and the inner bottom plate 35 are an integral structure, formed by bending a straight plate.

[0044] Specifically, such as Figure 2 As shown, in one embodiment, the air outlet 11 is offset from the air inlet of the air filter device 40.

[0045] In the above configuration, the air inlet of the air filter device 40 and the air outlet 11 of the inner door panel assembly 10 are staggered. This helps to form a tortuous airflow channel within the airflow buffer layer 30. External airflow passing through the airflow buffer layer 30 will form vortices, increasing resistance and thus weakening the kinetic energy of rainwater impurities. Simultaneously, the tortuous airflow channel effectively buffers the velocity of impurities entrained in the air, preventing them from keeping up with the change in airflow direction. Furthermore, the greater gravity of the impurities makes them easily separated from the airflow. This further enhances the filtration effect of the electrical cabinet door.

[0046] Specifically, such as Figure 4 As shown, in one embodiment, the inner door panel assembly 10 includes a heat dissipation ventilation duct 12 and an internal circulation fan 13.

[0047] The heat dissipation and ventilation duct 12 is installed inside the airflow buffer interlayer 30, and the inner cavity of the heat dissipation and ventilation duct 12 is not connected to the airflow buffer interlayer 30. The internal circulation fan 13 is connected to the inner cavity of the heat dissipation and ventilation duct 12 and the inner cavity of the electrical cabinet.

[0048] It should be noted that the air inlet of the air filter device 40 and the air outlet 11 of the inner door panel assembly 10 are staggered and interspersed in the heat dissipation ventilation duct 12 in the airflow buffer layer 30. This special design helps to form a tortuous airflow channel. When the external airflow flows through the heat dissipation ventilation duct 12, it will form a vortex, increase the resistance, and thus weaken the kinetic energy of rainwater impurities.

[0049] Meanwhile, the tortuous airflow channel effectively buffers the speed of rainwater impurities carried in the air, preventing them from keeping up with the change in airflow direction. Furthermore, the greater gravity of these impurities makes them easily separated from the airflow. As they pass through the airflow buffer layer 30, they quickly fall onto the inner lower plate 32 under gravity and slide out of the electrical cabinet door, preventing the accumulation of impurities inside the door and further ensuring efficient filtration and easy maintenance.

[0050] Specifically, such as Figures 2 to 4 As shown, in one embodiment, the inner door panel assembly 10 includes a plurality of heat dissipation and ventilation ducts 12, which are spaced apart along a first direction and extend along a second direction.

[0051] Specifically, such as Figures 2 to 4 As shown, in one embodiment, the inner door panel assembly 10 includes two heat dissipation ventilation ducts 12.

[0052] Of course, depending on the actual situation, three or more heat dissipation and ventilation ducts 12 can be installed.

[0053] Specifically, such as Figure 1 As shown, in one embodiment, the heat dissipation ventilation duct 12 is a circular pipe.

[0054] It should be noted that the heat dissipation and ventilation duct 12 is not limited to round tubes, but can also be square tubes, finned ventilation tubes, simple heat exchangers, etc.

[0055] Specifically, such as Figure 1 As shown, in one embodiment, the inner door panel assembly 10 further includes a fan mounting box 14, which is fixedly connected to the outer door panel 20 and is used to install the internal circulation fan 13.

[0056] It should be noted that the internal circulation fan 13 does not necessarily have to be installed on the inner door panel assembly 10; it can also be installed directly on the electrical cabinet.

[0057] Specifically, such as Figure 3 As shown, in one embodiment, the fan mounting box 14 is disposed on one side of the airflow buffer interlayer 30, and it shares a first inner side plate 33 with the airflow buffer interlayer 30. The first inner side plate 33 is provided with a through hole, and the heat dissipation ventilation pipe 12 passes through the through hole and communicates with the internal circulation fan 13.

[0058] It should be noted that a sealing element is provided on the outer periphery of the heat dissipation ventilation duct 12 to seal the gap between the heat dissipation ventilation duct 12 and the through hole.

[0059] Specifically, such as Figure 3As shown, in one embodiment, the fan mounting box 14 further includes an upper box plate, a lower box plate, and an encapsulation plate. The upper box plate is provided with a flange, and a connecting hole is provided on the flange. A connecting bolt passes through the connecting hole to realize the screw connection and fixation between the fan mounting box 14 and the outer door plate 20.

[0060] Specifically, such as Figure 3 As shown, in one embodiment, the encapsulation plate is provided with mounting holes for mounting the internal circulation fan 13.

[0061] Specifically, such as Figure 3 As shown, in one embodiment, the inner door panel assembly 10 further includes an inner door frame 15, and an airflow buffer layer 30 is embedded in the inner door frame 15.

[0062] In the above configuration, the inner door frame 15 serves as a structural component, which strengthens the overall structural strength of the electrical cabinet door, ensuring that it meets the strength requirements.

[0063] Specifically, such as Figure 3 As shown, in one embodiment, the inner door frame 15 includes two first door reinforcing ribs 151, a second door reinforcing rib 152, and a third door reinforcing rib 153.

[0064] Among them, two first door reinforcing ribs 151 are spaced apart along the second direction. The second door reinforcing rib 152 is connected to one end of the two first door reinforcing ribs 151, and the third door reinforcing rib 153 is connected to the other end of the two first door reinforcing ribs 151. The middle of the third door reinforcing rib 153 is cut off, and the airflow buffer interlayer 30 is partially embedded at the cut-off point.

[0065] Specifically, such as Figure 1 As shown, in one embodiment, the inner door panel assembly 10 further includes a sealing strip 70, which is disposed on the outer periphery of the inner door frame 15 for sealing the gap between the inner door panel assembly 10 and the outer door panel 20.

[0066] Specifically, such as Figures 2 to 4 As shown, in one embodiment, the electrical cabinet door also includes a door lock 50, which is disposed on the inner door panel assembly 10.

[0067] Optionally, such as Figure 3 As shown, in one embodiment, the door lock 50 is disposed on the second door reinforcing rib 152.

[0068] Specifically, such as Figure 1 As shown, in one embodiment, the electrical cabinet door also includes a hook 60, which is disposed on the outer door panel 20.

[0069] The hook 60 is used to flip the electrical cabinet door onto the electrical cabinet.

[0070] Specifically, such as Figure 1As shown, in one embodiment, the electrical cabinet door also includes a handle 80, which is disposed on the outer door panel 20.

[0071] Combination Figures 1 to 4 The following describes a complete embodiment of this application:

[0072] The invention provides an electrical cabinet door that combines ventilation filtration and heat dissipation, installed on the electrical cabinet. A ventilation filter is installed on the outer door panel 20 to filter impurities in the external cooling air entering the electrical cabinet. The outer door panel 20 and the airflow buffer layer 30 form an air duct chamber, through which an internally circulating heat dissipation ventilation duct 12 passes. External cold air flows through the outer wall of the heat dissipation ventilation duct 12, while hot air from the non-ventilated chambers (the inner cavity of the electrical cabinet) circulates within its inner cavity. This duct can form a heat exchange within the air duct chamber to reduce the temperature of the non-ventilated chambers within the electrical cabinet.

[0073] When the electrical cabinet is in operation, the external cold air passing through the ventilation filter completes the initial filtration of the air entering the cabinet, which contains impurities such as rainwater, dust, and particles. This device also features a special filtration design based on the principles of inertia and centrifugal sedimentation, achieving both efficient ventilation and efficient filtration, as detailed below:

[0074] 1. An airflow buffer layer 30 is formed between the outer door panel 20 and the inner door panel assembly 10. This layer provides a buffer area for airflow to prevent rainwater and impurities from being directly brought into the electrical cabinet by the airflow.

[0075] 2. By staggering the air inlets and outlets 11 of the ventilation filters and installing heat dissipation and ventilation ducts 12 within the airflow buffer layer 30, the air filtration function of the electrical cabinet door is enhanced.

[0076] Meanwhile, external cold air is drawn into the cabinet's external circulation cooling system, passing sequentially through the ventilation filter, outer door panel 20, cooling ventilation duct 12, and air outlet 11 before entering the cabinet's external circulation cooling system duct. Hot air from the non-ventilated chambers inside the cabinet is drawn in by the internal circulation fan 13 from the right side (see...). Figure 3 The air is drawn into the cooling ventilation duct 12, and after heat exchange with the outside cold air, it is then drawn into the left side (see...). Figure 3 The air blown out by the internal circulation fan 13 returns to the non-ventilated chamber inside the cabinet. The electrical cabinet door of this invention combines the functions of air filtration and internal circulation heat dissipation, with a compact and aesthetically pleasing structure that does not occupy external space.
