Technical Field

[0001] This utility model belongs to the field of reactor technology, specifically relating to a reactor core. Background Technology

[0002] A reactor, also called an inductor, is a passive component used to change the phase relationship between current and voltage in an AC circuit. The iron core in a reactor mainly serves to enhance inductance, improve magnetic field energy storage capacity, improve linearity, and reduce size.

[0003] In related technologies, E-type and I-type iron cores are generally used, which means combining an E-type iron core and an I-type iron core together. The inventory management of both E-type and I-type iron cores is complicated, the production cost is high, and the space in between is insufficient, which is not conducive to winding. Utility Model Content

[0004] The purpose of this invention is to propose a reactor core that solves the problems of complex inventory management, high production costs, and insufficient intermediate space in the related technologies for both Type E and Type I cores, which are not conducive to winding.

[0005] Therefore, this utility model provides a reactor core, comprising: two identical core components fixedly connected symmetrically, with a gap provided between the centers of the two core components.

[0006] Preferably, the core component includes a main body, a first protrusion, and a second protrusion, wherein the first protrusion is disposed at both ends of the main body, and the second protrusion is disposed at the center of the main body.

[0007] Preferably, the length of the first protrusion is greater than that of the second protrusion.

[0008] Preferably, a gap is formed between the second protrusions of the two core components.

[0009] Preferably, the ratio of the length of the first protrusion to the thickness of the main body is in the range of 1:1 to 1:3.

[0010] Preferably, the ratio of the width of the first protrusion to the width between the first protrusion and the second protrusion is 1:1 to 1:3.

[0011] Preferably, the ratio of the width of the first protrusion to the width of the second protrusion is 1:1 to 1:3.

[0012] Preferably, the width of the core component is in the range of 48-104 mm.

[0013] Preferably, the height of the core component is in the range of 15-39mm.

[0014] Preferably, the material of the core component is silicon steel plate.

[0015] Beneficial effects:

[0016] 1. This utility model provides a reactor core formed by welding two identical core components together. Only one type of core component needs to be manufactured, reducing production costs. Simultaneously, the increased space between the two core components facilitates the winding process and improves winding efficiency. Attached Figure Description

[0021] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0022] Example 1:

[0023] like Figure 2 As shown, this is an E-type iron core, which combines an E-type iron core 2 and an I-type iron core 3. Managing the inventory of both E-type iron core 2 and I-type iron core 3 is complex, production costs are high, and the insufficient space in between is detrimental to winding.

[0024] Therefore, the following are provided: Figure 1 The reactor core shown includes two identical core components 1 that are fixedly connected symmetrically to each other, with a gap provided between the centers of the two core components 1.

[0025] The core component 1 includes a main body 11, a first protrusion 12 and a second protrusion 13. The first protrusion 12 is located at both ends of the main body, and the second protrusion 13 is located at the center of the main body.

[0026] The length of the first protrusion 12 is greater than that of the second protrusion 13. A gap is formed between the second protrusions 13 of the two core components 1.

[0027] The ratio of the length H1 of the first protrusion 12 to the thickness H2 of the main body 11 is in the range of 1:1 to 1:3. Among them, 1:1.5, 1:2 or 1:2.5 are optional, and 1:2 is preferred.

[0028] The ratio of the width L1 of the first protrusion 12 to the width L2 between the first protrusion 12 and the second protrusion 13 is 1:1 to 1:3. Optionally, it can be 1:1.5, 1:2, or 1:2.5, with 1:2 being the preferred ratio.

[0029] The ratio of the width L1 of the first protrusion 12 to the width L3 of the second protrusion 13 is 1:1 to 1:3. Optionally, it can be 1:1.5, 1:2, or 1:2.5, with 1:2 being the preferred ratio.

[0030] The width of the core component 1 ranges from 48 to 104 mm. Among them, 48 mm, 64 mm, 76 mm, 84 mm, 96 mm or 104 mm are optional.

[0031] The height of the core component 1 ranges from 15 to 39 mm. Among them, the optional heights are 20 mm, 24 mm, 23.75 mm, 28.5 mm, 26.25 mm, 31.5 mm, 30 mm, or 36 mm.

[0032] The core component 1 is made of silicon steel plate.

[0033] Instructions for use: Fix one core component 1 with a clamp, place another core component 1 opposite it, and press it together from above using a press. By welding two identical core components 1 together, only one type of core component 1 needs to be produced, reducing production costs. Simultaneously, the increased space between the two core components 1 facilitates the winding process and improves winding efficiency.
