Description

Novel oil-guiding formula transformer radiator

Technical field

The utility model relates to a kind of field transformer, is specifically related to a kind of Novel oil-guiding formula transformer radiator.

Background technology

The radiating effect of transformer depends on the structure of radiator to a great extent, the heat spreader structures that used in the market, it comprises oil inlet pipe, oil return pipe and connects one group of fin between oil inlet pipe and oil return pipe, the deep fat of being drawn by transformer enters from oil inlet pipe, be diverted in the heat radiation chamber of one group of fin and dispel the heat, transformer oil after cooling is drawn from oil return pipe, enters in transformer, so carries out circulating cooling.The radiator of this structure mainly has the following disadvantages: because oil inlet pipe is straight strip structure, obviously exist and be assigned to the inhomogeneous situation of distribution of oil mass in each fin, near fin oil-in in oil inlet pipe, because it is nearer apart from transformer, transformer oil is process first, and its oil mass receiving is larger; Contrary, away from the fin of oil inlet pipe oil-in, because it is far away apart from transformer, transformer oil is first assigned to compared with on the near fin of transformer, is then assigned to compared with on transformer fin far away, and its oil mass receiving is less, cause its heat-sinking capability limited, invalid area of dissipation is larger; And record according to experiment, from transformer outer end fin farthest, it is best that itself and surrounding air convection current and radiant heat change condition, suppose that its flow is identical with the flow of other fin, transformer oil cooling heat dissipation is inside fastest, and the straight strip structure of oil inlet pipe not only can not play good radiating effect, and causes in the fin away from transformer, the flow rate of its transformer oil is lower, still has improved space.
