Transformer heat dissipation device

The utility model provides a transformer radiating device which comprises a radiator, an oil inlet pipe and an oil return pipe, and the radiator is respectively communicated with an oil inlet and an oil return port of a transformer oil tank through the oil inlet pipe and the oil return pipe. The radiator is of a hollow structure, and a phase-change material insertion layer of a honeycomb columnarstructure is embedded into the hollow structure of the radiator. Compared with a traditional radiator, the heat dissipation device can increase the heat dissipation area and is good in heat dissipation effect, especially when the top layer oil temperature is too high due to the abnormal operation state, the top layer oil temperature can be rapidly cooled in time through phase change material intercalation, and normal operation of equipment is guaranteed. 本实用新型提供一种变压器散热装置，包括：散热器、进油管和回油管，散热器分别通过进油管、回油管与变压器油箱的进油口和回油口连通；散热器为中空结构，在散热器的中空结构内嵌入有蜂窝状柱形结构的相变材料插层。相比传统的散热器，本散热装置能够增大散热面积，散热效果好，特别是非正常运行状态导致顶层油温过热时，通过相变材料插层，能够对顶层油温及
