Description

Technical Field

[0001] This utility model relates to the field of low-voltage control cabinets, and in particular to a low-voltage intelligent control cabinet with a heat dissipation structure. Background Technology

[0002] Traditional low-voltage intelligent control cabinets have many technical limitations during long-term use, mainly in terms of insufficient heat dissipation efficiency and inconvenient maintenance and operation.

[0003] Most existing control cabinets adopt a fixed installation structure. The dense arrangement of internal equipment results in limited heat dissipation space. Relying solely on simple ventilation holes or a single fan for heat dissipation is insufficient to effectively reduce the temperature inside the cabinet. In particular, local overheating is prone to occur in high-temperature environments or under high loads, which seriously affects the service life and operational stability of electronic equipment.

[0004] Meanwhile, traditional cabinet structure design does not fully consider the convenience of maintenance. When installing equipment and repairing lines, it is necessary to fully open the cabinet door and operate in a narrow space, which is not only inefficient, but also prone to causing cables to loosen or be damaged due to improper operation.

[0005] To address the aforementioned issues, this patent proposes an innovative solution that integrates efficient heat dissipation and convenient maintenance to overcome existing technological bottlenecks. Utility Model Content

[0006] The main purpose of this utility model is to propose a low-voltage intelligent control cabinet with a heat dissipation structure, which aims to solve the problems of narrow installation and maintenance space and inconvenient maintenance operations caused by the fixed installation structure of traditional cabinets.

[0007] To address the aforementioned issues, this utility model proposes a low-voltage intelligent control cabinet with a heat dissipation structure, comprising a cabinet body with an opening facing forward and a heat exchange window located at the center of the right end of the cabinet body, which is sealed by a filter screen. The right end of the cabinet body is connected to a telescopic window, inside which a heat dissipation box is installed. The front end of the heat dissipation box is rotatably connected to a cabinet door via a limiting seat, and the lower end of the cabinet body is connected to a conduit.

[0008] Preferably, the right side of the inner wall at both ends of the telescopic window is provided with a limiting slide groove, and both limiting slide grooves are provided inside the cabinet. The rear sides of both ends of the upper end of the heat dissipation box are connected with limiting slide rods.

[0009] Preferably, the two limiting slide rods are respectively inserted into the two limiting slide grooves and can slide and rotate within the two limiting slide grooves. Arc-shaped limiting holes are provided at the two front corners of the left inner wall of the cabinet.

[0010] Preferably, the two left corners of the rear end of the cabinet door are each connected to an arc-shaped limiting insert, and the two limiting inserts can rotate around the limiting seat and are respectively inserted into the two limiting holes.

[0011] Preferably, an air guide hole is provided at the center of the left end of the heat sink, a cooling fan is provided inside the air guide hole, and a blocking grille is provided on the left side of the cooling fan, and the blocking grille is snapped into the air guide hole.

[0012] Preferably, the rear right side of the heat dissipation box is connected to a connecting frame, and the connecting frame is located inside the cabinet and is attached to the inner wall of the rear end of the cabinet. Multiple heat absorption pipes are connected inside the connecting frame.

[0013] Preferably, each of the multiple heat-absorbing tubes has multiple heat-absorbing holes at its front end, and the front end of the connecting frame is connected to multiple mounting seats, which are located in front of the multiple heat-absorbing tubes and inside the cabinet.

[0014] Preferably, a telescopic slot is provided at the center of the lower end of the cabinet, and a telescopic connecting plate is provided inside the telescopic slot. The telescopic connecting plate is connected to the lower front side of the connecting frame and is slidably connected inside the telescopic slot, and the telescopic connecting plate is located at the rear end of the cabinet door.

[0015] Beneficial effects:

[0016] 1. The internal heat dissipation box of this utility model can move forward and rotate laterally as a whole, thereby completely removing the installed electrical equipment from the cabinet, improving the convenience of electrical equipment installation, maintenance, and wiring harness connection. Compared with traditional fixed control cabinets, this structure avoids the problem of narrow operating space, eliminates the need to disassemble the cabinet for maintenance, significantly improving work efficiency. At the same time, the linkage mechanism ensures that the wiring harness remains stably connected during movement, avoiding damage caused by pulling.

[0017] 2. The cabinet door of this utility model adopts an arc-shaped limiting insert that matches the corresponding hole in the cabinet body. When the cabinet door is closed, it automatically inserts and locks, and works with the right-end lock to fix it to the cabinet body, ensuring that the heat dissipation box and electrical equipment can be locked inside the cabinet body and protecting the safety of the internal equipment.

[0018] 3. This utility model achieves automatic monitoring and adjustment of the cabinet temperature through the linkage control of the temperature sensor and the cooling fan. The heat dissipation system adopts a combination of active air intake and passive convection, using heat absorption pipes to directionally extract hot air from around the equipment and introducing external cold air through heat exchange windows protected by filters, forming an efficient heat exchange cycle, thereby intelligently controlling the internal temperature of the cabinet and ensuring stable operation of electronic equipment at a suitable temperature.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To achieve the above-mentioned utility model objectives, such as Figures 1-6As shown, this utility model provides a low-voltage intelligent control cabinet with a heat dissipation structure, including a cabinet body 1. The cabinet body 1 opens forward, and a heat exchange window is provided inside the center of the right end of the cabinet body 1, which is sealed by a filter screen. A telescopic window 2 is connected to the right end of the cabinet body 1, and a heat dissipation box 3 is installed inside the telescopic window 2. A cabinet door 4 is rotatably connected to the front end of the heat dissipation box 3 via a limit seat. A conduit 5 is connected to the lower end of the cabinet body 1. A connecting frame 12 is connected to the rear right end of the heat dissipation box 3, and the connecting frame 12 is located inside the cabinet body 1 and fits against the inner wall of the rear end of the cabinet body 1. Multiple mounting seats 15 are connected to the front end of the connecting frame 12. The system is centrally controlled and managed through a low-voltage control cabinet. The electrical equipment of the low-voltage system is installed inside the cabinet 1 through multiple mounting bases 15, and internal heat dissipation is achieved through the heat dissipation box 3 and the connecting frame 12. The front end is sealed through the cabinet door 4. The connecting harness of the low-voltage system is electrically connected to the electrical equipment through the conduit 5. The heat dissipation box 3 can slide forward inside the telescopic window 2 and rotate at the front end of the telescopic window 2. The heat dissipation box 3 drives the connecting frame 12 and multiple mounting bases 15 to move out of the cabinet 1, which makes it more convenient for the installation, maintenance and wiring connection of electrical equipment.

[0030] Preferably, the telescopic window 2 has limit grooves 6 on the right side of the inner walls at both the top and bottom ends, and both limit grooves 6 are located inside the cabinet 1. Limit rods 7 are connected to the rear sides of both ends of the upper end of the heat dissipation box 3. The two limit rods 7 are respectively inserted into the two limit grooves 6 and can slide and rotate within the two limit grooves 6. A telescopic slot 16 is provided at the center of the lower end of the cabinet 1. A telescopic connecting plate 17 is provided inside the telescopic slot 16. The telescopic connecting plate 17 is connected to the lower front end of the connecting frame 12 and slidably connected inside the telescopic slot 16. The telescopic connecting plate 17 is located at the rear end of the cabinet door 4. During the process of moving the electrical equipment out of the cabinet 1, the telescopic window 2 and the heat dissipation box 3 can move through the limit grooves 6 at both ends. The lever 7 is used to limit the movement of the heat sink 3, allowing it to slide forward within the limit groove 6 via the limit slide 7. When the heat sink 3 and the limit slide 7 slide to the frontmost position, the heat sink 3 moves the connecting frame 12 and multiple mounting seats 15 to the front opening of the cabinet 1. At this time, the heat sink 3 is rotated to the left around the limit slide 7, causing the heat sink 3 to move the connecting frame 12 and multiple mounting seats 15 out of the cabinet 1. This makes it easier to install, maintain, and connect the electrical equipment of the low-voltage system. After the installation, maintenance, and wiring harness connection are completed, the connecting frame 12 and mounting seats 15 are moved back into the cabinet 1 by the rotation and sliding of the heat sink 3, and the electrical equipment is moved back into the cabinet 1 together.

[0031] During the process of moving electrical equipment out of the cabinet 1, the conduit 5 and the telescopic connecting plate 17 move together to the outside of the front end of the cabinet 1 under the action of the connecting frame 12, and remain in the same position with the electrical equipment installed at the front end of the multiple mounting seats 15, ensuring the stable connection of the wiring harness during the process of moving electrical equipment out of the cabinet 1.

[0032] Preferably, arc-shaped limiting holes 8 are provided at the two front corners of the inner wall on the left side of the cabinet body 1, and arc-shaped limiting plates 9 are connected at the two left corners of the rear end of the cabinet door 4. The two limiting plates 9 can rotate around the limiting seat and are respectively inserted into the two limiting holes 8. During the process of the cabinet door 4 rotating around the limiting seat and blocking the front end of the cabinet body 1, the cabinet door 4 drives the two limiting plates 9 to rotate around the limiting seat together, so that the two limiting plates 9 gradually insert into the two limiting holes 8. The two limiting holes 8 and the two limiting plates 9 can limit the position between the left end of the cabinet door 4 and the cabinet body 1. When the cabinet door 4 completely blocks the front end of the cabinet body 1, the right end of the cabinet door 4 can be limited and locked by the internal lock, thereby completely locking the position of the cabinet body 1 and the cabinet door 4, and thus locking the position of the heat dissipation box 3, the connecting frame 12, the mounting base 15, and the electrical equipment installed at the front end of the mounting base 15, ensuring the structural stability of the low-voltage control cabinet.

[0033] Preferably, an air guide hole is provided at the center of the left end of the heat dissipation box 3, and a cooling fan 10 is installed inside the air guide hole. A blocking grille 11 is provided on the left side of the cooling fan 10, and the blocking grille 11 is snapped into the air guide hole. Multiple heat absorption pipes 13 are connected inside the connecting frame 12. Multiple heat absorption holes 14 are provided at the front end of each heat absorption pipe 13, and multiple mounting seats 15 are located in front of the multiple heat absorption pipes 13 and inside the cabinet 1. During the operation of the electrical equipment inside the low-voltage control cabinet, the electrical equipment will generate heat. At this time, the cabinet door 4 is equipped with a temperature control unit. The low-voltage control cabinet is equipped with a temperature sensor controller. Therefore, the temperature sensor controller can sense the temperature inside the cabinet 1 and control the cooling fan 10 to run when the temperature exceeds the set value. The cooling fan 10 draws hot air from inside the cabinet 1 into the heat sink 3 through the connecting frame 12, the heat absorption pipe 13 and the heat absorption hole 14, and blows it out from the opening at the left end of the heat sink 3. At the same time, the cabinet 1 draws in cold air from the outside through the heat exchange window set inside the right end, thereby cooling down the inside of the cabinet 1 and intelligently controlling the temperature inside the cabinet to ensure the normal operation of the electrical equipment inside the cabinet 1.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
