Thermal transport property, is passed to the heat of thermal objects outside thermal source rapidly by the phase transformation of heat pipe therein working medium.Heat pipe has
High thermal conductivity, is the superconductor of heat, without working power, and energy complete independently heat conducts cooling work, so, heat pipe skill
Art can provide a kind of cooling effectiveness height for oil-immersed power transformer, and cost is low, the small cooling radiating mode of maintenance.
Utility model content
The purpose of this utility model is not high for current oil-immersed power transformer cooling effectiveness, or cooling structure is complicated
Heat pipe cooling heat dissipation technology is applied to by the problem of cost is big there is provided a kind of cooling structure of new oil-immersed power transformer
The cooling of oil-immersed power transformer, the heat of transformer oil carries out fast exchange by heat pipe with extraneous, with less
Cost, it is ensured that temperature of oil in transformer is in allowed band, it is ensured that the safety and economic operation of transformer.
To solve the above problems, the utility model is adopted the following technical scheme that：
Technical scheme 1：A kind of cooling structure of new oil-immersed power transformer, uses operating temperature for 0~250 DEG C
Normal temperature heat pipe, heat pipe one end be evaporator section (abbreviation hot junction), other end be condensation segment (abbreviation cold end), heat pipe is vertically put
Put, inside its evaporator section insertion major and minor fuel tank of transformer and conservator thermal source, condensation segment is exposed in atmosphere.Work as heat pipe evaporator section
When heated, the liquid in capillary evaporates rapidly, and steam flows to condensation segment under small pressure differential, and condensation segment discharges to air
Go out heat, then refrigerant vapor regelation is into liquid, and worker quality liquid flows back to evaporation along effect of the porous material by capillary force again
Section.Whole work process circulation is more than, and heat reaches condensation segment by the evaporator section of heat pipe, realizes that the heat exchange to transformer is cooled down.
Technical scheme 2：A kind of cooling structure of new oil-immersed power transformer, increases in oil tank of transformer top half
Plus auxiliary fuel tank, auxiliary fuel tank connects with main fuel tank and radiating tube respectively, constitutes the circulating oil path of closed loop；Insertion normal temperature heat in auxiliary fuel tank
