Abstract

This utility model belongs to the technical field of dry-type transformers, specifically a dry-type transformer with a high-efficiency heat dissipation structure. It includes a base frame, and further includes: a heat dissipation component disposed at the top middle section of the base frame; a transformer main unit disposed at the top of the heat dissipation component; a heat exchange component disposed on the outside of the transformer main unit; and a compensation component disposed at the outlet end of the heat exchange component. This utility model provides a dry-type transformer with a high-efficiency heat dissipation structure. By using air cooling to lower the temperature of the coolant, the coolant can more effectively absorb and conduct heat, which is then carried away by the air cooling system. This indirect cooling method improves the overall heat dissipation efficiency, especially in high-temperature environments, where the coolant temperature can be better controlled, preventing the transformer from overheating. Conversely, when directly using air cooling to dissipate heat from a dry-type transformer, the fan needs to withstand a large thermal load, which may increase the system's energy consumption and burden.
