Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for elevator control cabinets, specifically to a resistive heat dissipation device for elevator control cabinets. Background Technology

[0002] The resistor heat dissipation device for elevator control cabinets is a device used to dissipate heat from the resistor box installed on the top of the elevator control cabinet.

[0003] Based on the above, the inventors have discovered that there are currently many resistor heat dissipation devices for elevator control cabinets on the market. However, the common method for these devices involves workers creating numerous ventilation holes in the resistor box's outer casing to dissipate the heat generated. In the hot weather of southern regions, the air temperature around the resistor box is too high and the air circulation rate is poor, resulting in ineffective heat dissipation for the resistor box in the elevator control cabinet and reducing the device's practicality. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a resistor heat dissipation device for elevator control cabinets, aiming to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] The present invention relates to a resistive heat dissipation device for an elevator control cabinet, comprising a cabinet body, an air guide column at the top of the cabinet body, a plurality of connecting pipes on the inner wall of the air guide column, a blower mechanism at the top of the cabinet body, and a shielding mechanism on the outer wall of the air guide column.

[0006] The blower mechanism includes:

[0007] The first fan has its bottom end fixed to the top end of the cabinet. One end of the first fan is provided with an air guide pipe. The inner wall of the air guide pipe is provided with an extension pipe. The extension pipe is located at the top end of the cabinet. The outer wall of the extension pipe is fixed with a cover plate. The outer wall of the cover plate matches the inner wall of the air guide pipe.

[0008] As a preferred embodiment of this utility model, a second fan is fixed to the inner wall of the cabinet, and an extension plate is provided on one side of the second fan. The outer wall of the extension plate is fixed to the inner wall of the cabinet.

[0009] As a preferred embodiment of this utility model, the inner wall of the cabinet is provided with a dustproof net, which is located on one side of the extension plate.

[0010] As a preferred technical solution of this utility model, the inner wall of the air guide column is fitted with a plurality of air-guiding columns, and the outer walls of the plurality of air-guiding columns are fitted with the top of the inner wall of the cabinet.

[0011] As a preferred embodiment of this utility model, the blocking mechanism includes:

[0012] A baffle plate, the outer wall of which slides against one side of the air guide column, is located at the top of the cabinet.

[0013] As a preferred embodiment of this utility model, both sides of the cover plate are fixed with ring plates, and the inner walls of the two ring plates are threaded with studs, the bottom ends of the two studs being threaded with the inner wall of the cabinet.

[0014] As a preferred technical solution of this utility model, two concave plates are fixed on one side of the dustproof net, and a card block is fixed on the outer wall of each of the two concave plates. Two card slots are opened on one side of the cabinet, and the inner wall of each of the two card slots matches the outer wall of the card block.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this solution, the outer wall of the baffle is slid against one side of the air guide column, so that the bottom end of the baffle abuts against the top of the cabinet. The outer wall of the stud is threaded through the inner wall of the ring plate until the bottom end of the stud is threaded into the inner wall of the cabinet. Thus, the baffle is securely installed on the outer wall of the air guide column. The first fan is controlled to inject air into the interior of the extension tube, so that the air is blown and cooled by the air guide column. This prevents the air blown out of the inner wall of the connecting pipe from overflowing, so that the cold air guided by the connecting pipe is sealed and injected into the interior of the resistor box, thus making the resistor box better cooled by air blowing.

[0017] 2. This solution involves sliding the concave plate along the inner wall of the cabinet, causing the locking block on the outer wall of the concave plate to engage with the inner wall of the slot. This securely mounts the dustproof net on the inner wall of the cabinet, allowing for airflow and heat dissipation. The second fan, via an expansion plate, amplifies the airflow direction and, through the airflow column, initially cools the inverter installed inside the cabinet. This provides a wider range of airflow and heat dissipation for the inverter installed on the inner wall of the cabinet, preventing excessive internal temperature from causing the resistors to overheat. This improves the heat dissipation of the elevator control cabinet's resistors and effectively enhances the device's performance. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figures 1-5 As shown, the resistive heat dissipation device for the elevator control cabinet of this utility model includes a cabinet body 1, an air guide column 2 at the top of the cabinet body 1, a plurality of connecting pipes 3 on the inner wall of the air guide column 2, a blower mechanism 4 at the top of the cabinet body 1, and a shielding mechanism 5 on the outer wall of the air guide column 2.

[0027] Hair dryer component 4 includes:

[0028] The first fan 41 is fixed at its bottom end to the top end of the cabinet 1. One end of the first fan 41 is provided with an air guide pipe 42. The inner wall of the air guide pipe 42 is provided with an extension pipe 43. The extension pipe 43 is located at the top end of the cabinet 1. The outer wall of the extension pipe 43 is fixed with a cover plate 44. The outer wall of the cover plate 44 is matched with the inner wall of the air guide column 2.

[0029] As attached Figure 1 and Figure 5As shown, a second fan 6 is fixed to the inner wall of the cabinet 1. An extension plate 7 is provided on one side of the second fan 6. The outer wall of the extension plate 7 is fixed to the inner wall of the cabinet 1. A dustproof net 8 is provided on the inner wall of the cabinet 1. The dustproof net 8 is located on one side of the extension plate 7. Two concave plates 10 are fixed to one side of the dustproof net 8. A locking block 11 is fixed to the outer wall of each of the two concave plates 10. Two locking slots 12 are opened on one side of the cabinet 1. The inner walls of the two locking slots 12 are matched with the outer walls of the locking blocks 11 to provide a wider range of airflow for cooling the inverter installed on the inner wall of the cabinet 1, and to prevent the temperature of the resistor from rising due to excessive internal temperature of the cabinet 1.

[0030] As attached Figure 2 and Figure 3 As shown, the inner wall of the air guide column 2 is fitted with several air intake columns 9, and the outer walls of the several air intake columns 9 are fitted with the top of the inner wall of the cabinet 1, which facilitates the diversion of air to dissipate heat from the heat-generating components inside the cabinet 1 and accelerates the internal air circulation rate.

[0031] As attached Figure 1 , Figure 4 and Figure 5 As shown, the blocking mechanism 5 includes:

[0032] The outer wall of the shield 51 slides against one side of the air guide column 2. The shield 51 is set at the top of the cabinet 1. Both sides of the shield 51 are fixed with ring plates 52. The inner walls of the two ring plates 52 are threaded with studs 53. The bottom ends of the two studs 53 are threaded with the inner wall of the cabinet 1, so that the air force blows the heat of the resistor box through the air guide column 2, and prevents the air blown out of the inner wall of the connecting pipe 3 from overflowing, so as to seal the cold air guided by the connecting pipe 3 into the interior of the resistor box.

[0033] Working principle: In use, slide the outer wall of the baffle 51 against one side of the air guide column 2, so that the bottom end of the baffle 51 abuts against the top end of the cabinet 1. Use the threaded connection between the outer wall of the stud 53 and the inner wall of the ring plate 52 until the bottom end of the stud 53 is threaded onto the inner wall of the cabinet 1. Thus, the baffle 51 is securely installed on the outer wall of the air guide column 2. Control the first fan 41 to inject airflow into the interior of the extension tube 43. The airflow, through the air guide column 2, blows air to cool the resistor box, preventing air blown out from the inner wall of the connecting tube 3 from escaping. This allows the cool air guided by the connecting tube 3 to be sealed and injected into the interior of the resistor box. To improve the heat dissipation of the resistor box, the concave plate 10 is slid along the inner wall of the cabinet 1, causing the dustproof net 8 to slide. This allows the locking block 11 fixed to the outer wall of the concave plate 10 to engage with the inner wall of the slot 12, ensuring the dustproof net 8 is securely installed on the inner wall of the cabinet 1 for heat dissipation. The second fan 6 is controlled to increase the direction of the airflow through the expansion plate 7, and the airflow column 9 provides initial cooling to the inverter installed inside the cabinet 1. This allows for wider cooling of the inverter installed on the inner wall of the cabinet 1, preventing the temperature inside the cabinet 1 from becoming too high and causing the resistor temperature to rise. This facilitates better heat dissipation of the resistor in the elevator control cabinet.
