Description

Technical Field

[0001] This utility model belongs to the field of electrical control cabinet technology, specifically relating to a moisture-proof electrical control cabinet structure with intelligent heat dissipation. Background Technology

[0002] An electrical control cabinet is a control cabinet (box) in which switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on a panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or alarmed by protective electrical appliances.

[0003] With the increasing integration of electronic components, the problems of heat dissipation and moisture protection inside electrical control cabinets are becoming increasingly prominent. Traditional electrical control cabinet structures often use a single cooling fan or heat sink for heat dissipation. However, this heat dissipation method is usually passive and cannot be intelligently adjusted according to the actual situation inside the electrical control cabinet, resulting in poor heat dissipation effect. Moreover, the importance of moisture protection is often overlooked. In humid environments, electronic components inside the electrical control cabinet are prone to moisture, leading to performance degradation, increased failure rate, and even safety accidents. Therefore, this utility model proposes a moisture-proof electrical control cabinet structure with intelligent heat dissipation. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1 to 5 This is the first embodiment of the present invention, which provides a technical solution: a moisture-proof electrical control cabinet structure with intelligent heat dissipation, including...

[0027] Cabinet 1;

[0028] The cabinet 1 includes an upper heat dissipation vent 11 on the top side wall and a lower heat dissipation vent 12 on the bottom side wall. An upper cooling fan 2, corresponding to the upper heat dissipation vent 11, is installed on the top side wall of the cabinet 1, and a lower cooling fan 3, corresponding to the lower heat dissipation vent 12, is installed on the bottom side wall of the cabinet 1. A temperature sensor 4, model HDC1080, is also installed on one inner wall of the cabinet 1. The temperature sensor 4 can detect the temperature inside the cabinet 1 in real time and send the temperature value to the controller inside the cabinet 1, causing... The controller determines whether heat dissipation is needed based on the current temperature value. When the temperature value exceeds the set threshold, the upper cooling fan 2 and the lower cooling fan 3 are activated. The lower cooling fan 3 draws outside air into the cabinet 1 through the lower heat dissipation port 12, and then the upper cooling fan 2 sends the air in the cabinet 1 out through the upper heat dissipation port 11, forming a bottom-in and top-out airflow, which effectively removes the heat in the cabinet 1 and realizes intelligent heat dissipation. When the temperature acquisition sensor 4 detects that the internal temperature of the cabinet 1 has dropped to the set safe value, the upper cooling fan 2 and the lower cooling fan 3 stop to reduce energy consumption.

[0029] And a moisture-proof and dehumidifying structure set in the center of the inner side of cabinet 1.

[0030] In this embodiment, preferably, the moisture-proof and dehumidification structure includes a base plate 51 fixed to the inner walls of both sides of the cabinet 1, a hollow dehumidification rack 52 welded and fixed between the two base plates 51, and a plurality of storage boxes 53 installed inside the hollow dehumidification rack 52. The storage boxes 53 contain a dehumidifying desiccant 54, which is specifically a silica gel desiccant made of silicate, non-toxic, odorless, tasteless, chemically stable, and has strong moisture absorption performance.

[0031] In this embodiment, preferably, side air inlets 55 are provided on both sides of the storage box 53, and a bottom air inlet 57 is provided on the bottom surface of the storage box 53. A baffle net 56 is installed inside both the side air inlets 55 and the bottom air inlet 57. The baffle net 56 ensures that air can pass normally through the side air inlets 55 and the bottom air inlet 57 into the inside of the storage box 53. Simultaneously, the baffle net 56 prevents the dehumidifying agent 54 inside the storage box 53 from falling out through the side air inlets 55 and the bottom air inlet 57. This allows air inside the cabinet 1 to enter the storage box 53 and fully contact the dehumidifying agent 54, thereby absorbing moisture from the air and achieving a dehumidification effect. This prevents excessive humidity inside the cabinet 1 from causing moisture damage to the electronic components inside the cabinet 1, thus playing a moisture-proof role.

[0032] In this embodiment, preferably, a hanging structure is also provided between the storage box 53 and the hollow dehumidifier rack 52.

[0033] In this embodiment, preferably, the hanging structure includes two side hanging blocks 531 welded and fixed to the front and rear surfaces of the storage box 53. The inner wall of the hollow dehumidifier rack 52 has a side sliding groove 521 corresponding to the side hanging blocks 531, and the top of the side sliding groove 521 communicates with the top surface of the hollow dehumidifier rack 52. The side hanging blocks 531 slide into the side sliding groove 521, so that the storage box 53 can be placed inside the hollow dehumidifier rack 52 from top to bottom during installation, and the side hanging blocks 531 slide into the side sliding groove 521. 1. Slide the storage box 53 into the side sliding groove 521, and the storage box 53 can be hung on the inside of the hollow dehumidifier rack 52 by the two side hanging blocks 531, which can quickly achieve installation. It is also convenient for the operator to quickly remove the storage box 53 to empty and replace the dehumidifier 54 inside. When replacing it, simply lift the storage box 53 so that the side hanging blocks 531 slide out from the top of the side sliding groove 521, and the storage box 53 can be easily removed from the inside of the hollow dehumidifier rack 52.

[0034] In this embodiment, preferably, an upper protective net is installed on the outer surface of the cabinet 1 relative to the upper heat dissipation vent 11, so that air can enter and exit normally through the upper heat dissipation vent 11, but can block foreign objects from entering through the upper heat dissipation vent 11.

[0035] In this embodiment, preferably, a lower protective net is installed on the outer surface of the cabinet 1 relative to the lower heat dissipation vent 12, so that air can enter and exit normally through the lower heat dissipation vent 12, but can block foreign objects from entering through the lower heat dissipation vent 12.

[0036] Example 2

[0037] Please see Figures 1 to 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that rubber pads 522 are embedded in the inner walls of both sides of the side sliding groove 521, and the side of the rubber pads 522 is provided with an integrated positioning protrusion 523. Both are made of fluororubber and will undergo elastic deformation when squeezed. Positioning slots 532 corresponding to the positioning protrusions 523 are opened on both sides of the side hanging block 531, and the positioning protrusions 523 are inserted into the positioning slots 532, so that the side hanging block 531 can be effectively limited after sliding into the side sliding groove 521, ensuring the installation stability of the storage box 53 during daily use. When the storage box 53 needs to be removed later, simply lift the storage box 53 with force, so that the positioning protrusions 523 are squeezed and undergo elastic deformation until the side hanging block 531 slides out smoothly from the side sliding groove 521.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
