Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to an iron core middle partition heat dissipation type reactor. Background Art

[0002] Reactors, also called inductors, are widely used in circuits. Because of the effect of electromagnetic induction in circuits, there is a certain inductance, which can prevent current changes. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with electricity is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid form, 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. The more scientific classification is that inductive reactance and capacitive reactance are collectively called reactors. However, since inductors first appeared in the past and were called reactors, the capacitors people are now referring to are capacitive reactances, and reactors refer specifically to inductors.

[0003] Silicon steel sheet core generates a magnetic field when AC current is passed through it. The high-order harmonics in the AC current will cause great losses to the core. The traditional reactor core is stacked together as a whole, with no heat dissipation space. Heat is easily accumulated and difficult to dissipate, resulting in high core temperature. Moreover, the product works at high temperature for a long time, which greatly reduces its lifespan and is not conducive to other electronic products near the customer. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a heat dissipation reactor with a core separated in the middle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The heat dissipation reactor is separated in the middle of the iron core, including a reactor body, the reactor body is provided with an iron core, a gap is opened horizontally in the middle of the iron core, a plurality of I-shaped stays are arranged uniformly in the horizontal direction in the gap, gap stays are filled between the I-shaped stays in the gap, an outer shell cover is provided on the outside of the reactor body, and limit plugs are symmetrically provided on the side walls of both sides of the outer shell cover, and a dustproof mechanism is installed between the limit plugs on both sides.

[0007] In addition, a preferred structure is that heat dissipation openings are provided through the side walls of both sides of the outer shell cover where the dustproof mechanism is installed, and the heat dissipation openings are arranged vertically and evenly.

[0008] In addition, a preferred structure is that the dustproof mechanism includes a fixed frame, and a dustproof net is arranged inside the fixed frame.

[0009] In addition, a preferred structure is that a slot is provided in the limiting plug block, and the fixing frame is inserted in the slot.

[0010] In addition, a preferred structure is that a silicone patch is attached to the side wall of the limiting plug block located at the slot, and the silicone patch is in contact with the surface of the fixing frame.

[0011] In addition, a preferred structure is that the I-shaped stay is in an I-shape.

[0012] The beneficial effects of the utility model are as follows: a gap is separated between the iron cores by the I-shaped support bars, which can effectively dissipate the heat of the iron cores and make them run at low temperatures, ensuring product performance while not only meeting customer requirements, but also having no heat radiation effect on adjacent products, and the dustproof mechanisms installed on both sides of the outer shell cover can ensure that the heat dissipation port can be ventilated while effectively preventing dust, and the disassembly method of the fixed frame being pulled out from the slot of the limiting plug block makes the cleaning and replacement of the dustproof mechanism more convenient.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5The heat dissipation reactor is separated in the middle of the core, including a reactor body 001, the reactor body 001 is provided with an iron core 1, a gap 11 is horizontally opened in the middle of the iron core 1, a plurality of I-shaped stays 12 are evenly arranged in the horizontal direction in the gap 11, and gap stays 5 are filled between the I-shaped stays 12 in the gap 11, and an outer shell cover 2 is provided on the outside of the reactor body 001, and limit plugs 4 are symmetrically provided on the side walls of both sides of the outer shell cover 2, and a dustproof mechanism 3 is installed between the limit plugs 4 on both sides. A gap 11 is separated by an I-shaped stay between the iron cores 1, which can effectively dissipate the heat of the iron core and make it run at a low temperature.

[0021] Among them, heat dissipation ports 21 are opened through the side walls of the outer shell cover 2 where the dustproof mechanism 3 is installed. The heat dissipation ports 21 are arranged vertically and evenly. The heat dissipation ports 21 facilitate the air inside the outer shell cover 2 to circulate with the outside, thereby achieving a heat dissipation effect.

[0022] In addition, the dustproof mechanism 3 includes a fixed frame 31, and a dustproof net 32 ​​is arranged inside the fixed frame 31. The dustproof net 32 ​​can play a certain dustproof role. After a cover plate is provided above the outer shell cover 2, the dustproof net 32 ​​can prevent internal dust from entering.

[0023] Moreover, a slot 41 is provided in the limiting plug 4, and the fixed frame 31 is inserted in the slot 41. A silicone patch 42 is attached to the side wall of the limiting plug 4 located at the slot 41. The silicone patch 42 is in contact with the surface of the fixed frame 31. The silicone patch 42 is convenient for increasing the friction with the fixed frame 31, thereby preventing the fixed frame 31 from falling off easily.

[0024] In addition, the I-shaped stay 12 is in an I-shape.

[0025] In this embodiment, the iron cores 1 are separated by using I-shaped stays 12 to open a gap 11 between the iron cores 1, thereby effectively dissipating heat, and gap stays 5 are filled in the gap 11, which can dissipate heat from the gap 11.

[0026] The dustproof mechanism 3 of the heat dissipation port 21 on both sides can effectively prevent dust, and the dustproof net 32 ​​can block dust from entering the outer shell cover 2 from the heat dissipation port 21, thereby preventing dust from damaging the internal reactor body 001. When the dustproof net 32 ​​is disassembled and cleaned, the fixed frame 31 is pulled out from the slot 41 of the limiting plug 4 to be cleaned and replaced. This replacement method is more convenient.

[0027] In the utility model, a gap 11 is separated by an I-shaped support bar 12 between the iron cores 1, which can effectively dissipate the heat of the iron core 1 and make it run at a low temperature, ensuring product performance while not only meeting customer requirements, but also having no heat radiation effect on adjacent products. The dustproof mechanism 3 installed on both sides of the outer shell cover 2 can ensure that the heat dissipation port 21 can be ventilated while effectively preventing dust, and the disassembly method of the fixed frame 31 being pulled out from the slot 41 of the limiting plug block 4 makes it more convenient to clean and replace the dustproof mechanism 3.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
