The utility model relates to the field of
transformer heat dissipation, and discloses a heat dissipation device for a
transformer, which comprises a heat dissipation part detachably arranged on a
transformer main body, the plurality of fan main bodies are arranged at the lower part in the shell; the plurality of heat pipes are uniformly arranged at the upper part in the shell; the radiating fins are mounted on the shell; and the plurality of telescopic heat dissipation fins are uniformly arranged on the two sides of the shell. By arranging the fan body, the
heat pipe, the heat dissipation fins and the telescopic heat dissipation fins, efficient heat dissipation is achieved, the fan body accelerates
heat transfer by forcing air to flow, the
heat pipe efficiently conducts heat to reduce
temperature difference, and the heat dissipation fins increase the contact area to strengthen convective heat exchange. The telescopic heat dissipation fins dynamically adjust the heat dissipation area to adapt to different working conditions and are particularly suitable for occasions with limited space and fluctuating heat dissipation requirements, efficient heat dissipation is guaranteed, meanwhile,
low noise and a compact structure are maintained, and multiple requirements of modern high-tech equipment are met.
