A new type of multi-level power distribution cabinet

Abstract

This invention proposes a novel multi-level power distribution cabinet, comprising a cabinet body and heat dissipation vents. Several heat dissipation vents are provided on both side walls of the cabinet body, and multiple compartments are arranged inside the cabinet body. The advantages of this invention are: a heat-conducting plate and heat sinks are installed on the back of the cabinet corresponding to each compartment, and multi-point interconnected heat-spreading strips are connected to the heat sinks. The heat-conducting plate can conduct heat generated in the corresponding compartment and transfer it to the numerous heat sinks, effectively increasing the heat dissipation area. The heat-spreading strips achieve uniform heat distribution, avoiding the problem of localized heat accumulation. A fan blows air along the heat sinks to increase the airflow velocity on their surface, quickly carrying away heat and further improving heat dissipation efficiency. The use of heat-spreading strips ensures a more uniform heat distribution among the heat sinks, avoiding localized overheating of electrical components due to uneven heat distribution. This design helps extend the service life of electrical components and improves the overall stability of the power distribution cabinet.

Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a novel multi-level power distribution cabinet. Background Technology

[0002] A multi-level distribution cabinet is a cabinet with one main door and several smaller doors. This type of cabinet is designed for convenient management and power distribution, while providing better equipment protection and operational ease of use. Multi-door distribution cabinets typically have a main door for overall access and maintenance. The interior is also divided into several smaller areas, each with its own door, allowing for individual operation and maintenance of specific equipment or wiring.

[0003] However, due to their multi-level design, these distribution cabinets are relatively large. The small compartments inside the cabinet are flanked by other compartments or large compartments, resulting in a small heat dissipation area. The heat generated in these compartments cannot be directly dissipated from the sides, leading to heat accumulation and excessively high local temperatures inside the distribution cabinet. This results in poor heat dissipation performance and low heat dissipation efficiency. Therefore, a new type of multi-level distribution cabinet is proposed to effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a novel multi-level power distribution cabinet to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a novel multi-level power distribution cabinet, including a cabinet body and heat dissipation vents. Several heat dissipation vents are provided on both side walls of the cabinet body. Multiple cabinet compartments are provided inside the cabinet body. Each cabinet compartment is movably connected to a compartment door, and each compartment door is equipped with a lock.

[0007] The bottom plate of the cabinet has wire holes of varying diameters.

[0008] A heat-conducting plate is fixedly connected to the back of the cabinet at the corresponding cabinet compartment. Several heat sinks are fixedly connected to the back of the heat-conducting plate, and the heat sinks are arranged vertically.

[0009] Each heat sink is fitted with a heat dissipation strip, which is a multi-bent strip.

[0010] Multiple fans are fixedly connected to the back of the cabinet. Each fan has a motor installed inside, and the output end of the motor is fixedly connected to several fan blades.

[0011] The air outlet of the fan faces upwards.

[0012] Preferably, in any of the above embodiments, the cabinet is made of several cold-rolled steel plates riveted together, and the heat dissipation vent faces downward.

[0013] The above technical solution is adopted: This power distribution cabinet is a multi-level power distribution cabinet. The cabinet body is equipped with multiple compartments. Each compartment is movably connected to a door, and the door is equipped with a lock. This power distribution cabinet design aims to facilitate the management and distribution of power, while providing better equipment protection and operational convenience.

[0014] Structural Features: The distribution cabinet features a main access door for overall access and maintenance. Simultaneously, the interior is divided into multiple smaller areas, each with its own access door, facilitating individual operation and maintenance of specific equipment or lines. The cabinet's internal layout is clearly divided into different functional areas, such as incoming line area, outgoing line area, circuit breaker area, and instrument area. This helps management and maintenance personnel quickly locate specific equipment or lines, improving work efficiency.

[0015] Preferably, the storage unit comprises one large vertical storage unit, two medium horizontal storage units, and two small horizontal storage units.

[0016] Preferably, in any of the above solutions, the wire holes are linearly arrayed on the bottom plate of the cabinet, and the heat-conducting plate is riveted or connected to the back plate of the cabinet by screws.

[0017] Preferably, the heat-conducting plate is made of silicone rubber and is in the form of a thin sheet.

[0018] Using the above technical solution: silicone rubber has excellent thermal conductivity and insulation properties.

[0019] Preferably, in any of the above embodiments, the heat sink is bonded to the heat-conducting plate, and the heat sink is made of ceramic.

[0020] The above technical solution utilizes ceramic materials, which offer fast heat dissipation and insulation.

[0021] The core structure of this device consists of a heat-conducting plate, heat sinks, heat spreader strips, a fan, a motor, and fan blades. Its key advantages are: heat-conducting plates and heat sinks are installed on the back of each compartment, with multiple heat spreader strips connecting the heat sinks. The heat-conducting plates conduct heat from the corresponding compartment and transfer it to the numerous heat sinks, effectively increasing the heat dissipation area. The heat spreader strips ensure even heat distribution, preventing localized heat accumulation. A fan blows air along the heat sinks, increasing the surface airflow and quickly removing heat, further improving heat dissipation efficiency. The heat spreader strips ensure a more uniform heat distribution between the heat sinks, preventing localized overheating of electrical components due to uneven heat distribution. This design helps extend the lifespan of electrical components and improves the overall stability of the distribution cabinet. The efficient heat dissipation design reduces the possibility of damage to electrical components due to overheating, lowering the frequency of maintenance and component replacement.

[0022] Preferably, as described in any of the above embodiments, the heat spreader is made of ceramic, and there are two connections between each heat sink and the heat spreader. The heat spreader is located 10-20 cm behind the cabinet. The fan is located below the heat sink and is installed behind the cabinet using screws. The fan has a ground clearance of 20-30 cm.

[0023] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0024] This new multi-level distribution cabinet utilizes a combination of heat-conducting plates, heat sinks, heat spreaders, fans, motors, and fan blades. Each compartment has a heat-conducting plate and heat sink installed on its back, with multiple heat spreaders connecting the heat sinks. The heat-conducting plates conduct heat from the corresponding compartment and transfer it to the numerous heat sinks, effectively increasing the heat dissipation area. The heat spreaders ensure even heat distribution, preventing localized heat accumulation. Fans blow air along the heat sinks, increasing airflow and quickly removing heat, further improving heat dissipation efficiency. The heat spreaders ensure more uniform heat distribution among the heat sinks, preventing localized overheating of electrical components due to uneven heat distribution. This design helps extend the lifespan of electrical components and improves the overall stability of the distribution cabinet. The efficient heat dissipation design reduces the likelihood of component damage due to overheating, lowering the frequency of maintenance and component replacement.
