The underground transformer structure of radiation energy consumption.
The utility model is achieved through the following technical solutions：A kind of underground transformer structure, including foundation pit, it is described
Bottom of foundation ditch is fixed with pedestal close to centre position, and transformer is provided with the pedestal, and the foundation pit place suitable for reading is additionally provided with
Cover board, is provided with cabinet on the cover board, vent window is provided between the cabinet and cover board, is provided with the vent window some
Downward thermal vias, further includes at least one heat pipe, and the heat pipe lower end is located inside transformer, and the heat pipe upper end is located at
Intracavitary in vent window.
Further, the pedestal includes being fixed on be parallel to each other two rectangular cross-sections or trapezoidal of bottom of foundation ditch
Clump, the transformer includes base, and the base is fixed on clump by positioning bolt.
Further, the cabinet is advertising light box type switchgear.
Further, the cover board is cement cover board, its thickness is 20-30mm.
Further, the thermal vias is blinds hole obliquely.
Further, the heat pipe selects annular gravity heat pipe.
Further, sealing ring is provided between the heat pipe and transformer, the heat pipe is made of copper pipe, the copper
Condensate liquid is filled with pipe.
Further, the copper pipe, which is located on the outer wall of the part in vent window, is provided with fin.
The beneficial effects of the utility model are：Radiated using heat pipe, change the mentality of designing of traditional heat sinks,
Break away from the simple traditional heat-dissipating pattern that more preferable heat dissipation effect is obtained by Wind Volume fan, use easy to install, good heat dissipation effect,
The cooling requirements of underground transformer are very suitable for, there is good economic and social benefit.
