[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 to Figure 2 As shown, an embodiment of the utility model 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, 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.

[0026] 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.

[0027] Among them, 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; 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 connected assembly plate within the above angle range can achieve good magnetic conductive effect and heat dissipation effect on the coil body. For example, the angle between the magnetic conductive plate and the connected assembly plate can be specifically set to about 135 degrees.

[0028] Specifically, Figure 1 As shown, in the first embodiment, the first magnetic conductive plate 20 is an arc-shaped plate, and / or the second magnetic conductive plate 40 is an arc-shaped plate. Compared with the flat plate structure, the arc-shaped plate structure can increase the distance between the first magnetic conductive plate 20, the second magnetic conductive plate 40 and the coil body, thereby facilitating air flow and improving the heat dissipation effect. In addition, the arc-shaped plate can better match the extension direction of the magnetic flux lines of the coil body, thereby improving the magnetic conductive effect.

[0029] Further, the inner surface of the first magnetic conductive plate 20 is a part of a cylindrical surface, and the radius of the cylindrical surface is 15 to 30 mm; and / or, the inner surface of the second magnetic conductive plate 40 is a part of a cylindrical surface, and the radius of the cylindrical surface is 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 is a part of a cylindrical surface, which is convenient for processing and is conducive to improving the magnetic conductive effect. Setting the radius of the cylindrical surface to 15 to 30 mm can ensure good magnetic conductive effect and heat dissipation effect.

[0030] like Figure 2 As shown, in the second embodiment, the first magnetic conductive plate 20 includes a plurality of first sub-plates 21 connected in sequence, and an angle is formed between two adjacent first sub-plates 21; and / or, the second magnetic conductive plate 40 includes a plurality of second sub-plates 41 connected in sequence, and an angle is formed between two adjacent second sub-plates 41. That is, the first magnetic conductive plate 20 or the second magnetic conductive plate 40 can also achieve the purpose of forming an obtuse angle with the assembly plate by using a combination of multiple sub-plates.

[0031] 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.

[0032] The first sub-plate 21 may be a flat plate or an arc-shaped plate, and the second sub-plate 41 may be a flat plate or an arc-shaped plate. Figure 2 In the embodiment, 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.

[0033] In this solution, the cavity formed by the magnetic conductor is used to install the coil body, and the distance between the inner surface of the first magnetic conductor plate 20 and the coil body is 3 to 10 mm, and the distance between the inner surface of the second magnetic conductor plate 40 and the coil body is 3 to 10 mm. This ensures that there is enough clearance between the magnetic conductor plate and the coil body for ventilation and heat dissipation.

[0034] In this solution, the magnetic conductor is an integrally formed sheet metal structure. The magnetic conductor is set as a sheet metal structure, which has a simple structure, low cost and is easy to process.

[0035] The first assembly plate 10 and the second assembly plate 30 are provided with assembly holes for connection with other structures.

[0036] The present solution also provides an electromagnetic coil, which includes a magnetic conductor and a coil body, wherein the magnetic conductor is the magnetic conductor mentioned above, and the coil body is installed in the cavity of the magnetic conductor. In this solution, the angle between the first magnetic conductive plate 20 and the first assembly plate 10 and 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 and the second assembly plate 30 is set to an obtuse angle. Compared with the existing solution using right angles, it can better match the extension direction of the magnetic flux lines of the coil body in the magnetic conductor, 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.

[0037] The present solution also provides a reversing valve, which includes a valve body and an electromagnetic coil installed on the valve body, and the electromagnetic coil is the above-mentioned electromagnetic coil. The reversing valve can be a four-way reversing valve, etc. The electromagnetic coil can change the flow direction in the reversing valve by controlling the on and off of the power supply, thereby realizing the switching of the flow direction of the fluid in the air conditioning system and the like.
