Abstract
The invention discloses a heat dissipation structure of an electric reactor. The heat dissipation structure comprises a magnetic core, wherein the magnetic core comprises an upper iron yoke, a lower iron yoke and two core pillars, the two core pillars are perpendicularly arranged between the upper iron yoke and the lower iron yoke, each core pillar is wound with a coil winding, an upper heat dissipation cover plate is arranged on the upper iron yoke of the magnetic core, a lower heat dissipation cover plate is arranged at the bottom of the lower iron yoke of the magnetic core, a fixing piece is arranged in the middle of the upper heat dissipation cover plate, the fixing piece and the lower heat dissipation cover plate are connected through a pull rod, and an upper surface of the upper heat dissipation cover plate and a lower surface of the lower heat dissipation cover plate adopt uneven structures. When the electric reactor works, heat generated by the magnetic core is conducted to the upper heat dissipation cover plate and the lower heat dissipation cover plate and emitted through the upper heat dissipation cover plate and the lower heat dissipation cover plate, the heat dissipation effect of the electric reactor can be improved under the limited size, and temperature rise of the electric reactor is reduced.
Description
Technical field
The present invention relates to transformer technology field, particularly to a kind of reactor radiator structure.
Background technology
For reactor, being lost and have two kinds: one loss being magnetic core, two is the loss of coil, and when the input harmonics composition of reactor is higher, core loss accounts for the biggest ratio.When reactor cannot be arranged more heat dissipation wind channel by volumetric constraint, how to process heat dissipation problem, be that reactor design must take into.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of reactor radiator structure, the radiating effect of reactor can be improved, reduce the temperature rise of reactor.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of reactor radiator structure, including a magnetic core, this magnetic core includes upper yoke, lower yoke and two stem stems, these two stem stems are vertically installed between upper yoke and lower yoke, coil windings it is wound with respectively on each stem stem, the upper yoke of described magnetic core is provided with heat-dissipating cover plate, the bottom of the lower yoke of magnetic core is provided with lower heat-dissipating cover plate, the middle part of described upper heat-dissipating cover plate is provided with a stator, connected by pull bar between stator and lower heat-dissipating cover plate, the upper surface of described upper heat-dissipating cover plate and the lower surface of lower heat-dissipating cover plate are rough structure.
Further, the material of described upper heat-dissipating cover plate and lower heat-dissipating cover plate is aluminum material.
Further, described stator is U-shaped.
Further, the upper end of described pull bar is provided with the locking nut being positioned at above stator.
Further, it is connected to a pull bar between two ends and the lower heat-dissipating cover plate of described stator.
The invention has the beneficial effects as follows: the upper yoke of the magnetic core in the present invention is provided with heat-dissipating cover plate, lower yoke is provided with lower heat-dissipating cover plate, thus when reactor works, the heat that magnetic core produces is transmitted on heat-dissipating cover plate and lower heat-dissipating cover plate, distributed by upper heat-dissipating cover plate and lower heat-dissipating cover plate again, the radiating effect of reactor under limited volume, can be improved, reduce the temperature rise of reactor.The middle part of upper heat-dissipating cover plate is provided with a stator, is connected by pull bar between stator and lower heat-dissipating cover plate, thus makes upper heat-dissipating cover plate and lower heat-dissipating cover plate all fit tightly with magnetic core by the cooperation of pull bar and stator, it is ensured that the radiating effect of magnetic core.The outer surface of upper heat-dissipating cover plate and lower heat-dissipating cover plate is rough structure, such that it is able to increasing heat radiation area, more improves radiating effect.
