Abstract
Description
Technical Field
[0001] This utility model relates to the field of substation ventilation technology, specifically a substation cabin ventilation duct heat dissipation grid. Background Technology
[0002] The interior of a substation compartment typically houses transformers, switchgear, and other equipment that generate a significant amount of heat during operation. Poor heat dissipation can lead to excessively high equipment temperatures, affecting normal operation and even causing malfunctions. Therefore, substation compartments are generally equipped with ventilation ducts for heat dissipation, and the outer ends of these ducts are fitted with grids.
[0003] A search revealed that patent application number 202221350247.2 discloses a modular prefabricated substation, including a cabin, cooling fans, smoke alarm equipment, cables, and line limiting and fixing mechanisms. The cooling fans are installed inside the cabin on both sides near the top. Ventilation openings are connected to one side of the cooling fans and located on both sides of the cabin. A dustproof net is installed on one side of the ventilation opening, and a mounting plate is connected to the other side of the dustproof net. The dustproof net is installed and removed using the mounting plate and screws. This invention utilizes smoke alarm equipment, communication equipment, and control room accessories. The smoke alarm equipment can detect a fire immediately and transmit the signal to the control room via the communication equipment, notifying the Fire Information Management Bureau immediately. When the temperature inside the cabin is high, the cooling fans, in conjunction with the ventilation openings, can cool the space inside the cabin. Thus, the dustproof net serves a dustproof function while providing ventilation.
[0004] The aforementioned application documents describe how cooling fans are used to dissipate heat from the substation. However, for heat dissipation through the air duct, a grid is needed to block the outer end of the air duct. But the existing grid has a fixed structure, making it difficult to efficiently dissipate the hot air discharged from the air duct according to the requirements.
[0005] Therefore, we propose a substation cabin air duct-guided heat dissipation grid. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a substation compartment air duct-guided heat dissipation grid, which solves the problem that existing devices are unable to efficiently guide airflow and dissipate heat from the substation compartment according to requirements.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a substation cabin air duct guiding heat dissipation grid, including an air duct installed on the outside of the substation cabin;
[0008] The outer end of the air duct is provided with a grid assembly, which includes a frame that is snapped onto the tail end of the air duct. A guide vane is fixedly installed on the inner side of the frame. The guide vane is installed at an oblique interval. Fifteen sets of guide vanes are provided on the inner side of the frame, and a guide slot is provided between adjacent guide vanes.
[0009] As a preferred embodiment of this utility model, the outer wall specifications of the card frame are adapted to the inner wall specifications of the air duct tail end, and mounting clips are fixedly installed at the four corners of the card frame. The mounting clips are provided with screw grooves, and the grid assembly is fixedly installed on the tail end of the air duct by four sets of bolts.
[0010] The mounting clips and screw grooves facilitate the fixing of the grid assembly to the tail end of the air duct, enabling efficient assembly and disassembly.
[0011] As a preferred embodiment of the present utility model, the tail end of the card frame is fitted with a grid plate that matches its inner diameter specification, and the grid plate has grid slot holes with regular hexagonal slots distributed in a filled manner.
[0012] The grid design ensures the aesthetics of the outer end of the air duct, and its shape also increases the contact area with the outer airflow, thus ensuring heat exchange efficiency.
[0013] As a preferred embodiment of this utility model, a corresponding flow guide plate is fixedly installed at the inner end of the card frame, and a rectangularly distributed heat-conducting plate is fixedly installed on the inner side wall of the card frame, and the heat-conducting plate is disposed between the flow guide plate and the grid plate.
[0014] The placement of the heat-conducting fins facilitates contact with the hot airflow passing through the inside of the grid assembly, ensuring effective heat exchange.
[0015] As a preferred embodiment of this utility model, the side wall of the guide plate is provided with guide grooves that are distributed vertically at intervals, and the guide grooves are oblique V-shaped grooves.
[0016] The design of the guide vanes and guide grooves facilitates the even distribution of airflow inside the duct and ensures the contact area between them as well as the subsequent heat exchange effect.
[0017] This utility model provides a substation cabin air duct-guided heat dissipation grid. It has the following beneficial effects:
[0018] This substation compartment air duct cooling grid, through the arrangement of components inside the grid assembly, enables the large-area contact of the exhaust hot airflow using guide vanes and guide grooves, and achieves efficient heat exchange with the heat-conducting plates. Finally, the heat-exchanged airflow is output by the grid plate. At the same time, the oblique direction of the guide vanes and the arrangement of the guide grooves on them can efficiently guide the hot airflow, ensuring the exhaust effect. This solves the problem that existing devices are unable to efficiently guide and dissipate heat in the substation compartment according to the requirements. Attached Figure Description

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.
[0026] Please see Figure 1-5 This utility model provides a technical solution: a substation cabin air duct heat dissipation grid, including an air duct 1 disposed on the outside of the substation cabin; a grid assembly 2 is disposed at the outer end of the air duct 1, the grid assembly 2 includes a frame 21 that is snapped onto the tail end of the air duct 1, a guide plate 25 is fixedly installed on the inner side of the frame 21, the guide plate 25 is installed at an oblique interval, fifteen sets of guide plates 25 are disposed on the inner side of the frame 21, and a guide slot is disposed between adjacent guide plates 25;
[0027] The substation compartment air duct cooling grid, through the arrangement of the components inside the grid assembly 2, allows the exhaust hot airflow to come into large-area contact with the guide vanes 25 and guide channels 26, and to achieve efficient heat exchange with the heat-conducting plates 24. Finally, the heat-exchanged airflow is output by the grid plate 22. At the same time, the oblique orientation of the guide vanes 25 and the arrangement of the guide channels 26 on them can efficiently guide the hot airflow, ensuring the exhaust effect. This solves the problem that existing devices are unable to efficiently guide and dissipate heat in the substation compartment according to requirements.
[0028] Example 2:
[0029] The outer wall specifications of the frame 21 are compatible with the inner wall specifications of the tail end of the air duct 1. Mounting clips 23 are fixedly installed at the four corners of the frame 21. The mounting clips 23 have screw grooves, and the grid assembly 2 is fixedly installed on the tail end of the air duct 1 by four sets of bolts. The mounting clips 23 and screw grooves facilitate the fixed installation of the grid assembly 2 on the tail end of the air duct 1, so as to facilitate efficient assembly and disassembly.
[0030] The end of the card frame 21 is fitted with a grid plate 22 that matches its inner diameter specification, and the grid plate 22 has grid slots with hexagonal grooves distributed in a filled manner; the grid plate 22 can first ensure the aesthetics of the outer end of the air duct 1, and secondly, its shape can also ensure the contact area with the outer airflow and ensure the heat exchange effect.
[0031] A corresponding flow guide plate 25 is fixedly installed at the inner end of the card frame 21, and a rectangular heat conduction plate 24 is fixedly installed on the inner side wall of the card frame 21. The heat conduction plate 24 is located between the flow guide plate 25 and the grid plate 22. The heat conduction plate 24 is positioned to facilitate contact with the hot airflow passing through the inner side of the grid assembly 2, thereby ensuring the heat exchange effect.
[0032] The side wall of the guide vane 25 is provided with guide grooves 26 that are distributed vertically at intervals, and the guide grooves 26 are oblique V-shaped grooves; the arrangement of the guide vane 25 and the guide grooves 26 facilitates the even distribution of the airflow flowing inside the air duct 1, and ensures the contact area between them and the subsequent heat exchange effect.
[0033] The working principle and usage process of this utility model are as follows: When the device is required to work, the grid plate 22 is clamped at the tail end of the frame 21, and the grid assembly 2 is clamped at the tail end of the substation cabin air duct 1. The bolts are used to thread the assembly. When the substation cabin discharges hot airflow through the air duct 1, the guide plate 25 and the guide groove 26 guide the hot airflow and make large-area contact with it. The heat-conducting plate 24 can further ensure the heat exchange effect. Finally, the grid plate 22 discharges the heat-exchanged airflow, thus achieving the effect of efficient airflow guidance and heat exchange for the substation cabin.
