Description

Technical Field

[0001] This utility model relates to a control cabinet, and more particularly to a control cabinet that facilitates heat dissipation. Background Technology

[0002] When electrical control cabinets are in use, they generate heat. In the existing technology, cooling fans and exhaust vents are usually installed on the control cabinet to dissipate the heat inside the cabinet to the outside. However, in actual use, the heat dissipation efficiency is low and the heat dissipation effect is poor. In addition, there are some resistors inside the cabinet that generate a lot of heat, which greatly increases the heat generation inside the cabinet. Furthermore, in order to reduce the impact on other components inside the cabinet, other components need to be placed away from the resistors, resulting in low space utilization inside the cabinet.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0038] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] Please see Figures 1 to 3 As shown, a heat-dissipating control cabinet corresponding to a preferred embodiment of the present invention includes: a cabinet body 100, with an internal mounting cavity 110 for mounting components; a heat dissipation air conditioner 200 disposed on the side of the cabinet body 100 and connected to the mounting cavity 110; a resistor 300 disposed on the top of the cabinet body 100 and electrically connected to the components in the mounting cavity 110; a heat dissipation cover 400 fixed to the top of the cabinet body 100 and covering the resistor 300; and a heat dissipation fan 500 disposed on the heat dissipation cover 400 and used to dissipate heat from the heat dissipation cover 400 to the outside.

[0041] This invention improves heat dissipation within the mounting cavity 110 by incorporating a heat dissipation air conditioner 200 connected to the mounting cavity 110. Furthermore, by installing a heat dissipation shroud 400 and a cooling fan 500 on the top of the cabinet 100, and placing a resistor 300 within the heat dissipation shroud 400, the resistor 300 can dissipate heat independently under the action of the cooling fan 500. This avoids increasing the heat generation within the mounting cavity 110, reduces the power consumption of the heat dissipation air conditioner 200, lowers costs, and ensures that the resistor 300 does not affect the components within the mounting cavity 110, thus improving the space utilization of the mounting cavity 110.

[0042] Furthermore, the cooling air conditioner 200 can blow air in different directions as needed to improve the heat dissipation effect. The side of the cabinet 100 is provided with an air outlet 120 that is connected to the cooling air conditioner 200. The air outlet 120 is located in the approximate middle area of ​​the cabinet 100, so that the cooling air conditioner 200 can evenly and quickly distribute cold air vertically to various areas of the mounting cavity 110.

[0043] Preferably, the cabinet 100 is provided with an exhaust hole (not shown) near the top. The exhaust hole is connected to the mounting cavity 110. The airflow in the mounting cavity 110 can be discharged to the outside through the exhaust hole. Since the exhaust hole is located near the top of the cabinet 100, and since the heat flow is usually concentrated at the top of the mounting cavity 110, the above structure can more easily discharge the heat flow and improve the cooling effect.

[0044] Furthermore, the heat sink 400 is a square shroud with a perforated structure on all four sides. At least one cooling fan 500 is positioned on top of the heat sink 400. The cooling fan 500 is adapted to blow external airflow into the heat sink 400, allowing the heat inside the heat sink 400 to be expelled through the perforations. Alternatively, the cooling fan 500 can also draw the heat inside the heat sink 400 to the outside, in which case external cold air can flow into the heat sink 400 through the perforations.

[0045] Specifically, the heat sink 400 has heat dissipation vents 410 on all four sides, and there are multiple heat dissipation vents 410 arranged in a ring around the circumference of the heat sink 400. Preferably, there are multiple rings of heat dissipation vents 410, which are arranged at intervals along the vertical direction.

[0046] Furthermore, the control cabinet also includes a base 600 and shock absorbers 700 disposed between the base 600 and the bottom of the cabinet 100. Multiple shock absorbers 700 are arranged at intervals along the circumference of the control cabinet. By adopting the above structure, the control cabinet can be used in ship hulls or other easily swaying environments, thereby achieving the purpose of shock absorption and stabilization of the cabinet 100, and preventing damage to the components inside the cabinet 100.

[0047] Specifically, the shock absorber 700 includes an upper connecting seat 710, a lower connecting seat 720, and a spring 730. The upper connecting seat 710 is fixedly connected to the bottom of the cabinet 100, and the lower connecting seat 720 is fixedly connected to the base 600. The spring 730 is a cylindrical spring and is disposed between the upper connecting seat 710 and the lower connecting seat 720, with its axis parallel to the horizontal direction. When the cabinet 100 receives an impact, the spring 730 is adapted to buffer the cabinet 100 radially.

[0048] The upper connecting base 710 includes an upper connecting block 711, a lower connecting block 712 located below the upper connecting block 711, and a locking member 713 connecting the two. The upper connecting block 711 is fixed to the cabinet 100 and has a first mounting groove 7111 recessed inward from its bottom surface. There are multiple first mounting grooves 7111, which are spaced apart along the axial direction of the spring 730. The lower connecting block 712 is fixed to the base 600 and located below the upper connecting block 711. The lower connecting block 712 has a second mounting groove 7121 recessed inward from its top surface. The second mounting groove 7121 corresponds one-to-one with the first mounting groove 7111. Both the first mounting groove 7111 and the second mounting groove 7121 are arc-shaped grooves and are adapted to cooperate to form a circular hole through which the spring 730 passes. The locking member 713 is specifically a threaded connector such as a bolt or screw, which is adapted to fasten the spring 730 to the circular hole by tightening the upper connecting block 711 and the lower connecting block 712. The locking elements 713 are staggered with the mounting grooves, and preferably there are multiple locking elements 713, which are spaced apart along the axial direction of the spring 730. The lower connecting seat 720 and the upper connecting seat 710 have the same structure. The upper side of the spring 730 passes through the circular hole of the upper connecting seat 710, and the lower side of the spring 730 passes through the circular hole of the lower connecting seat 720.

[0049] By adopting the above-mentioned structure, the shock absorber 700 is easy to install and has good reliability after installation. The shock absorber 700 has a larger contact area with the cabinet 100 and the base 600, which effectively improves the shock absorption effect.

[0050] Furthermore, the control cabinet includes a cabinet door 130 movably connected to the cabinet body 100 and adapted to the switch mounting cavity 110. The back of the cabinet door 130 is provided with an openable or foldable platform 140 to facilitate the placement of debugging equipment by equipment commissioning personnel. Specifically, a linkage structure can be provided between the cabinet door 130 and the platform 140 to allow the platform 140 to be flipped upwards to fit against the back of the cabinet door 130, or flipped downwards to make the platform 140 perpendicular to the cabinet door 130, as needed. The linkage structure is a known structure and will not be described in detail here.

[0051] Furthermore, the cabinet door 130 is equipped with a display screen 150 that is electrically connected to the components inside the mounting cavity 110. The display screen 150 is embedded in the cabinet door 130 and is arranged at an outward tilt in the vertically downward direction. The embedded structure of the display screen 150 can effectively protect the display screen 150, and the outward tilt in the vertically downward direction facilitates monitoring the equipment status and operation, and also allows the equipment status to be observed even when the external brightness is too high.

[0052] Preferably, there are two cabinet doors 130, arranged in a double-door configuration, with the table body 140 and the display screen 150 respectively installed on different cabinet doors 130, thereby avoiding mutual restriction between the table body 140 and the display screen 150.

[0053] Furthermore, the top surface of the cabinet 100 is provided with a cable routing port 160 that communicates with the mounting cavity 110. The cable routing port 160 is covered by a cover plate 170. The top surface of the cabinet 100 is provided with several second adjustment holes 180 arranged at intervals along the direction perpendicular to the back of the cabinet 100. The cover plate 170 is provided with several first adjustment holes 171. When the cover plate 170 is in the preset position of completely closing the cable routing port 160, the second adjustment holes 180 and the first adjustment holes 171 correspond one-to-one. Fasteners are provided between the second adjustment holes 180 and the first adjustment holes 171. The fasteners are threaded connectors such as screws and bolts.

[0054] By adopting the above structure, the size of the cable tray 160 can be adjusted adaptively, which facilitates the electrical connection between components inside the cabinet 100 and external equipment, while improving the cleanliness inside the cabinet 100 and preventing external dust from entering the cabinet 100 due to an excessively large opening. One or more cable trays 160 can be provided as needed; this utility model does not limit this. The cover plate 170 corresponds one-to-one with the cable tray 160.

[0055] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
