[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] As shown in Figures 1 and 2, an embodiment of the present application provides a magnetic conductor, comprising a first assembly plate 10, a first magnetic conductive plate 20, a second assembly plate 30, and a second magnetic conductive plate 40 connected end to end in sequence, wherein the first assembly plate 10 and the second assembly plate 30 are arranged opposite to each other, and the first magnetic conductive plate 20 and the second magnetic conductive plate 40 are arranged opposite to each other; wherein the angle between the first magnetic conductive plate 20 and the first assembly plate 10 and the angle between the first magnetic conductive plate 20 and the second assembly plate 30 are both obtuse angles, and the angle between the second magnetic conductive plate 40 and the first assembly plate 10 and the angle between the second magnetic conductive plate 40 and the second assembly plate 30 are both obtuse angles.

[0027] In this scheme, the angle between the first magnetic conductive plate 20 and the first assembly plate 10, the second assembly plate 30 is set to an obtuse angle, and the angle between the second magnetic conductive plate 40 and the first assembly plate 10, the second assembly plate 30 is set to an obtuse angle. Compared with the existing scheme using right angles, it can better match the extension direction of the magnetic flux lines of the coil body in the magnetic conductive body, thereby improving the magnetic conductive effect, and can increase the gap between the first magnetic conductive plate 20, the second magnetic conductive plate 40 and the coil body, thereby improving the heat dissipation effect.

[0028] The angle between the first magnetic conductive plate 20 and the first assembly plate 10 is 95 to 150 degrees; the angle between the first magnetic conductive plate 20 and the second assembly plate 30 is 95 to 150 degrees; the angle between the second magnetic conductive plate 40 and the first assembly plate 10 is 95 to 150 degrees; and the angle between the second magnetic conductive plate 40 and the second assembly plate 30 is 95 to 150 degrees. Setting the angle between the magnetic conductive plate and the attached assembly plate within this range can achieve good magnetic conductivity and heat dissipation for the coil body. For example, the angle between the magnetic conductive plate and the attached assembly plate can be set to approximately 135 degrees.

[0029] Specifically, as shown in Figure 1, in the first embodiment, the first magnetic conductive plate 20 is a curved plate, and / or the second magnetic conductive plate 40 is a curved plate. Compared to a flat plate structure, the use of a curved plate structure can increase the distance between the first and second magnetic conductive plates 20, 40, and the coil body, thereby facilitating air flow and improving heat dissipation. In addition, the curved plate can better match the extension direction of the magnetic flux lines of the coil body, thereby improving the magnetic conductivity.

[0030] Furthermore, the inner surface of the first magnetic conductive plate 20 is a portion of a cylindrical surface with a radius of 15 to 30 mm; and / or the inner surface of the second magnetic conductive plate 40 is a portion of a cylindrical surface with a radius of 15 to 30 mm. The inner surface of the first magnetic conductive plate 20 or the inner surface of the second magnetic conductive plate 40 being a portion of a cylindrical surface facilitates processing and improves magnetic conductivity. Setting the cylindrical radius to 15 to 30 mm ensures excellent magnetic conductivity and heat dissipation.

[0031] As shown in Figure 2 , in the second embodiment, the first magnetic conductive plate 20 comprises a plurality of sequentially connected first sub-plates 21, with an angle formed between adjacent first sub-plates 21; and / or the second magnetic conductive plate 40 comprises a plurality of sequentially connected second sub-plates 41, with an angle formed between adjacent second sub-plates 41. In other words, the first magnetic conductive plate 20 or the second magnetic conductive plate 40 can also achieve an obtuse angle with the mounting plate by using a combination of multiple sub-plates.

[0032] The first magnetic conductive plate 20 or the second magnetic conductive plate 40 can be formed by bending an integral plate, or by connecting a plurality of separate sub-plates.

[0033] The first sub-plate 21 can be a flat plate or a curved plate, and the second sub-plate 41 can be a flat plate or a curved plate. For example, in Figure 2 , the first magnetic conductive plate 20 includes two first sub-plates 21, both of which are flat plates. The second magnetic conductive plate 40 includes two second sub-plates 41, both of which are flat plates.

[0034] In this embodiment, the coil body is mounted within the cavity formed by the magnetic conductors. The distance between the inner surface of the first magnetic plate 20 and the coil body is 3 to 10 mm, and the distance between the inner surface of the second magnetic plate 40 and the coil body is 3 to 10 mm. This ensures sufficient clearance between the magnetic plates and the coil body for ventilation and heat dissipation.

[0035] In this solution, the magnetizer is an integrally formed sheet metal structure, which is simple in structure, low in cost, and easy to process.

[0036] The first assembly plate 10 and the second assembly plate 30 are provided with assembly holes for connection with other structures.

[0037] This solution also provides an electromagnetic coil, comprising a magnetizer and a coil body, wherein the magnetizer is the aforementioned magnetizer, and the coil body is mounted within a cavity of the magnetizer. In this solution, the angles between the first magnetic conductive plate 20 and the first and second assembly plates 10, 30 are set to an obtuse angle, and the angles between the second magnetic conductive plate 40 and the first and second assembly plates 10, 30 are set to an obtuse angle. Compared to existing solutions employing right angles, this solution can better match the extension direction of the magnetic flux lines of the coil body within the magnetizer, thereby improving the magnetic conductivity. Furthermore, the solution can increase the gap between the first and second magnetic conductive plates 20, 40, and the coil body, thereby improving the heat dissipation effect.

[0038] This solution also provides a reversing valve, comprising a valve body and an electromagnetic coil mounted on the valve body. The electromagnetic coil is the aforementioned electromagnetic coil. The reversing valve may be a four-way reversing valve, for example. The electromagnetic coil can change the flow direction within the reversing valve by controlling the power supply on and off, thereby switching the flow direction of fluid within a system such as an air conditioner.

[0039] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
