Cooling device of transformer

The invention relates to the cooling technology of transformers, in particular to a transformer cooling device based on a liquid capillary network. In the cooling device of the transformer, the transformer and the converter unit of the circuit are integrally installed in a sealed insulating box body. The cooling device of the transformer comprises a capillary network which is arranged in the insulating box body and covers the outer surface of a potting layer of the transformer; a radiator which is arranged outside the insulating box body and is used for radiating the refrigerant in the capillary network; and a fluid pump which is used for driving the refrigerant to circularly flow between the capillary network and the radiator. The device can be used for cooling the transformer in a narrowspace in the insulating box body, and the heat dissipating capacity to the interior of the insulating box body is reduced while the heat of the transformer is taken away. 本发明涉及变压器的冷却技术，尤其涉及一种基于通液毛细管网的变压器冷却装置。在本发明提供的上述变压器的冷却装
