Problems solved by technology

[0002] Electromagnetic coils are used to control the flow of fluid and realize cooling and heating of air conditioners. However, electromagnetic coils will generate heat during long-term electrification. Occasionally, the voltage is too large, causing the coils to burn out. During this process, the coils may burn and cause disasters.

Embodiment 1

[0036] Such as Figures 1 to 3 As shown, the present invention provides an electromagnetic coil for air conditioning, including a coil body 1 and a magnetically permeable frame 2 with fire-resistant performance. The magnetically permeable frame 2 is sleeved outside the coil body 1. Frame 2 ensures the magnetic conduction function of the coil; the magnetic conduction frame 2 includes a side plate 21 with a “mouth” shape in cross section, an upper cover plate 22 located above the side plate 21 and a lower cover plate 23 located below the side plate 21. The plate 21 forms a closed whole with the upper cover plate 22 and the lower cover plate 23, and surrounds all six sides of the coil body 1, so as to prevent the occurrence of disasters caused by the fire of the coil and improve the safety of the use of the electromagnetic coil; the lower cover plate 23 is provided with There are at least two lower protrusions 231, and the lower protrusions 231 are located on the outer peripheral...

Embodiment 2

[0049] Such as Figures 4 to 6 As shown, the main difference between this embodiment and Embodiment 1 is that the side plate 21 includes an upper side plate 211 and a lower side plate 212, the lower cover plate 23 and the lower side plate 212 are integrally stamped and formed, and the upper side plate 211 and the upper cover plate 22 integrally stamped and formed.

[0050] The side plate 21 includes an upper side plate 211 and a lower side plate 212 , the lower cover plate 23 and the lower side plate 212 are integrally formed by stamping, and the upper side plate 211 and the upper cover plate 22 are integrally formed by stamping. The upper end surface of the lower side plate 212 is provided with a boss 24 , and the lower end surface of the upper side plate 211 is provided with a mounting hole 25 matching with the boss 24 . The advantage of this arrangement is that by dividing the side plate 21 into an upper side plate 211 and a lower side plate 212, the upper side plate 211 a...

Embodiment 3

[0054] Such as Figures 7 to 9 As shown, the main difference between this embodiment and Embodiments 1 and 2 is that the side plate 21 includes a first side plate 213 and a second side plate 214, and both the first side plate 213 and the second side plate 214 are in an “L” shape. , the first side plate 213 is integrally stamped and formed with the upper cover plate 22 , and the second side plate 214 is integrally stamped and formed with the lower cover plate 23 .

[0055] The side plate 21 includes a first side plate 213 and a second side plate 214, the first side plate 213 and the second side plate 214 are both in an "L" shape, the first side plate 213 is integrally stamped with the upper cover plate 22, the second The side plate 214 and the lower cover plate 23 are integrally formed by stamping. The first side plate 213 and the upper cover plate 22 are all provided with a boss 24, and the second side plate 214 and the lower cover plate 23 are all provided with a mounting ho...

Abstract

The invention provides an electromagnetic coil for an air conditioner. The electromagnetic coil comprises a coil body and a magnetic conductive frame having fire resistance performance. The magnetic conductive frame is arranged outside the coil body in a sleeving manner, the magnetic conductive frame comprises a side plate with the cross section being in a mouth shape, an upper cover plate locatedabove the side plate and a lower cover plate located below the side plate, the side plate, the upper cover plate and the lower cover plate form a closed whole, the six sides of the coil body is totally surrounded, a disaster caused by coil ignition is avoided, and the using safety of the electromagnetic coil is improved; at least two lower protrusions are arranged on the lower cover plate, the lower protrusions are located on the outer circumference side of the coil body to be used for limiting the horizontal position of the coil body, and therefore the coil body cannot move back and forth and left and right; the upper cover plate is provided with upper protrusions, the upper protrusions are used for limiting the upper and lower positions of the coil body, and therefore the coil body cannot move up and down; and the relative positions of the electromagnetic coil and the magnetic conductive frame are fixed, the fireproof function of the magnetic conductive frame is ensured, and the using safety of the electromagnetic coil is further ensured.

Description

technical field [0001] The invention relates to the technical field of electromagnetic coils, in particular to an electromagnetic coil for air conditioners. Background technique [0002] Electromagnetic coils are used to control the flow of fluid and realize cooling and heating of air conditioners. However, electromagnetic coils will generate heat during long-term electrification. Occasionally, the voltage is too large, causing the coils to burn out. During this process, the coils may burn and cause disasters. .
