Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of reactors, and particularly to a reactor winding ventilation device. Background Art

[0002] A reactor is also called an inductor. When a conductor is energized, a magnetic field will be generated within a certain space it occupies. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight energized conductor is small, and the generated magnetic field is not strong. Therefore, an actual reactor is a wire wound in the form of a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductive reactors and capacitive reactors are collectively called reactors. However, since inductors existed first in the past and were called reactors, the capacitors people talk about now are capacitive reactors, and reactors specifically refer to inductors.

[0003] The prior art has the following deficiencies: The existing reactors are fixed and heat-conducted by means of filling and wrapping on the outer layer. The structure is relatively cumbersome during specific production. At the same time, the traditional horizontal heat dissipation method has a poor heat dissipation effect on the reactors. Summary of the Invention

[0004] Therefore, the embodiments of the present invention provide a reactor winding ventilation device. By setting a ventilation mechanism, an outer layer heat dissipation ring, a middle layer heat dissipation ring, and an inner layer heat dissipation ring are sequentially sleeved horizontally outside the positioning cylinder. The first spacer block and the second spacer block provided between the outer layer heat dissipation ring, the middle layer heat dissipation ring, and the inner layer heat dissipation ring ensure the spacing between the outer layer heat dissipation ring and the middle layer heat dissipation ring, as well as between the middle layer heat dissipation ring and the inner layer heat dissipation ring. At the same time, multiple outer layer heat dissipation rings, middle layer heat dissipation rings, and inner layer heat dissipation rings are sequentially stacked and placed, and are positioned and fixed through the positioning card slots on the partition board. Vertical air gaps are generated in the vertical direction between the outer layer heat dissipation ring, the middle layer heat dissipation ring, and the inner layer heat dissipation ring, and horizontal air gaps are generated in the horizontal direction between the outer layer heat dissipation ring, the middle layer heat dissipation ring, and the inner layer heat dissipation ring, effectively increasing the heat dissipation space, facilitating the heat conduction of the reactor iron core through the positioning cylinder outward, with convenient installation and simple structure, effectively improving the heat dissipation efficiency and installation convenience of the reactor iron core, so as to solve the problems caused by the fact that the existing reactors are fixed and heat-conducted by means of filling and wrapping on the outer layer, the structure is relatively cumbersome during specific production, and the traditional horizontal heat dissipation method has a poor heat dissipation effect on the reactors.

[0036] The specific implementation scenario is as follows: When in use, the reactor core 1 is clamped into the interior of the positioning cylinder 3. The circular positioning cylinder 3 reduces the distance from the reactor core 1. Then, the outer heat dissipation ring 7, the middle heat dissipation ring 8, and the inner heat dissipation ring 9 are sequentially sleeved horizontally on the outer side of the positioning cylinder 3. The first spacer block 10 and the second spacer block 11 provided between the outer heat dissipation ring 7, the middle heat dissipation ring 8, and the inner heat dissipation ring 9 ensure the distances between the outer heat dissipation ring 7 and the middle heat dissipation ring 8, and between the middle heat dissipation ring 8 and the inner heat dissipation ring.

Then, the rotating platform 16 is rotated and adjusted at multiple angles through the rotating platform 16, which facilitates the installation convenience of the present invention. Then, the base 17 is moved through the universal wheels 18, which is convenient for quick movement. The heat conduction tape 12 is wound around the outer sides of the outer heat dissipation ring 7, the middle heat dissipation ring 8, and the inner heat dissipation ring 9 in the positive direction. Then, the outer sides of the outer heat dissipation ring 7, the middle heat dissipation ring 8, and the inner heat dissipation ring 9 of the next layer are wound with the heat conduction tape 12 in the reverse direction, which effectively winds and fixes the outer heat dissipation ring 7, the middle heat dissipation ring 8, and the inner heat dissipation ring 9, improves the fixing effect of the overall structure, and improves the stability of the heat conduction tape winding and fixing.

[0041] Working principle:
