Description

Technical Field

[0001] This application belongs to the field of equipment heat dissipation technology, specifically relating to a cooling device for a transformer group. Background Technology

[0002] In the specialty glass manufacturing industry, the channel and forming processes play a crucial role. Dry-type transformers are extremely common in these key stages, sometimes numbering in the hundreds. In actual installation, to meet the specific spatial layout requirements, these transformers are typically installed densely using mounting racks. This installation method often involves multi-layered structures, aiming to maximize the use of limited space resources.

[0003] These transformers generate a significant amount of heat during operation. However, in densely packed installations, the space for heat dissipation between the devices is severely limited, making it difficult to effectively release the heat. As the equipment temperature continues to rise, it not only threatens the lifespan and stability of the transformers themselves but may also adversely affect the surrounding environment and the smooth operation of the entire production line.

[0004] Existing technologies typically cool transformers by installing cooling fans on the outside. However, these fans encroach on the heat dissipation space, obstruct airflow, and affect heat dissipation efficiency. Furthermore, cooling fans near the center are exposed to high temperatures and are prone to damage due to excessive heat. Utility Model Content

Through the design of centralized air supply and decentralized air outlets, the heat dissipation efficiency is improved, space is saved, and the risk of equipment damage is reduced, thus solving the heat dissipation problem of transformer groups in dense installation.

[0006] This application provides a cooling device for a transformer bank, comprising:
