Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of central cabinets, in particular to a heat dissipation structure of a central cabinet in a substation. Background Art

[0002] The central cabinet in a substation is a critical piece of equipment for power distribution and control during tire production. It houses numerous electrical components, including circuit breakers, disconnectors, and transformers. In large tire manufacturing plants, large equipment such as vulcanizers draws significant amounts of power from the central cabinet during startup and operation, subjecting the components within to prolonged periods of high load. If the generated heat cannot be dissipated promptly, the cabinet temperature rises. High temperatures reduce the conductivity of the circuit breaker contact material, increasing contact resistance. Increased contact resistance increases the voltage drop across the contacts, further increasing heat generation and creating a vicious cycle. Furthermore, excessive temperatures degrade the insulation performance of the insulation material. The insulation material within the central cabinet is typically an organic polymer. Generally speaking, for every 10°C increase in temperature, the lifespan of the insulation material is approximately halved. This degraded insulation performance can cause short circuits, posing a serious threat to power supply security during tire production. Substations typically require heat dissipation structures to cool the interior of the central cabinet.

[0003] The existing device mainly dissipates heat from electronic components through air cooling components. The existing technology is similar to a central cabinet heat dissipation structure. The structure with patent number CN220156052U includes a cabinet, a heat dissipation mechanism is provided on the front surface of the cabinet, and a dust removal mechanism is provided on the top of the cabinet. The central cabinet heat dissipation structure, through the heat dissipation mechanism, is provided with a heat dissipation fan that is easy to install and disassemble. When the heat dissipation fan is damaged due to long-term overload operation, it can be disassembled and repaired in time, thereby achieving the purpose of convenient maintenance. When the heat dissipation fan rotates, the heat dissipation fan can transport external cold air to the interior of the cabinet, thereby achieving the purpose of heat dissipation of the cabinet. Through the dust removal mechanism, the motor drives the second flat gear and the first flat gear to rotate, driving the scraper to rotate. At this time, the scraper can scrape dust off the surface of the dustproof net to avoid clogging of the dustproof net due to excessive dust, ensuring that the dustproof net achieves its own heat dissipation purpose. However, there are still areas that can be optimized in this device.

[0004] The existing device mainly uses the air cooling component to dissipate heat for the central cabinet, which makes it easy for some devices to drive water vapor into the interior of the central cabinet, thereby causing some electronic components to rust and age easily. Secondly, some devices mainly fix the heat dissipation component inside the machine body, which makes it difficult for some devices to uniformly guide air to the electronic components inside the central cabinet, thereby causing some electronic components to have difficulty in uniformly dissipating heat. Furthermore, some devices mainly use scrapers to clean the dust on the dustproof net, which makes it difficult for some devices to clean the dust inside the filter holes, making some filters difficult to clean. Finally, some devices mainly fix the water cooling component on the machine body, which makes it difficult for some devices to quickly disassemble and assemble the water cooling structure of the heat dissipation component, thereby making it inconvenient to maintain the water cooling structure of the heat dissipation component, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a heat dissipation structure for the central cabinet of a substation is proposed. Summary of the Invention

The high-temperature and high-pressure condensate inside the heat pipe 115 is discharged into the cold liquid tank 113 through the expansion valve 117.
