Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil technology, and in particular to an air conditioner electromagnetic coil. Background Technology

[0002] The electromagnetic coil is an important component of the electromagnetic directional valve. Its main function is to change the flow direction within the electromagnetic directional valve by controlling the on and off of the power supply, thereby switching the flow direction of fluids in systems such as air conditioning. The electromagnetic coil includes a magnetic support and a coil body installed inside the magnetic support.

[0003] Existing magnetic guide brackets are usually fixed with an interference fit to the coil body, which is troublesome to install and the coil assembly will generate heat when working normally. Since the magnetic guide bracket is made of metal, its coefficient of thermal expansion is significantly different from that of the plastic on the outer surface of the coil assembly. Relative displacement occurs between the magnetic guide bracket and the coil assembly, eventually leading to fixation failure and a short service life of the electromagnetic coil. Utility Model Content

[0004] The purpose of this invention is to provide an air conditioner electromagnetic coil that solves the above-mentioned technical problems, is easy to install, and has a long service life.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air conditioner electromagnetic coil, including a magnetic guide frame and a coil body, the coil body is installed inside the cavity of the magnetic guide frame, the magnetic guide frame is an integrally formed structure and a linear dividing groove penetrating the magnetic guide frame is provided on one side, an installation hole is provided in the middle of the dividing groove, fixing plates are symmetrically provided on the inner walls of both sides of the dividing groove, a threaded rod is passed through between the fixing plates, and a nut is threadedly connected to the end of the threaded rod.

[0006] By adopting the above technical solution, a linear dividing groove is provided on one side of the magnetic guide frame. When the coil body needs to be installed, it is only necessary to squeeze the coil body into the inner cavity of the magnetic guide frame. At this time, a pre-tightening force will be generated on both sides of the dividing groove, firmly clamping the coil body inside the magnetic guide frame, which is convenient for installation. Moreover, due to the dividing groove, a space gap is provided between the plastic coil body and the metal magnetic guide frame to allow for expansion. The thermal expansion of the plastic coil body will be absorbed by the gap, reducing the stress on the magnetic guide frame and improving the service life. Fixing plates are fixed on both sides of the magnetic guide frame with the dividing groove. The fixing plates are connected by threaded rods. When tightening the nuts, the magnetic guide plates on both sides of the dividing groove can be brought closer together, increasing the pre-tightening force on both sides of the dividing groove, making the coil body more firmly clamped inside the magnetic guide frame, protecting the coil body. At the same time, when it is heated and slowly cooled, the metal magnetic guide frame recovers quickly while the coil body recovers more slowly, which may cause the clamping of the metal magnetic guide frame on the coil body to loosen. At this time, the nuts can be adjusted to ensure that the coil body is stably clamped. The setting of the fixing plates can also increase the heat dissipation area, assist in heat dissipation to a certain extent, and improve the heat dissipation efficiency.

[0007] A further feature of this invention is that the magnetic guide frame, threaded rod, and nut are made of metal conductors.

[0008] A further feature of this invention is that the magnetic guide frame includes two opposing magnetic guide plates, and the distance between the inner walls of the two magnetic guide plates is less than the width of the coil body.

[0009] A further feature of this invention is that the width of the dividing groove is less than 1 mm.

[0010] By adopting the above technical solution, the magnetic flux can be avoided from being affected by excessively large dividing slots.

[0011] A further feature of this invention is that the fixing plate is symmetrically provided with two sets, one upper and one lower.

[0012] By adopting the above technical solution and setting up two sets, upper and lower, uniform clamping of the coil body can be achieved.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this application, the magnetic guide frame is an integrally molded structure with a linear dividing groove on one side. When the coil body needs to be installed, the coil body only needs to be squeezed into the inner cavity of the magnetic guide frame. At this time, a pre-tightening force will be generated on both sides of the dividing groove, which will firmly clamp the coil body inside the magnetic guide frame, making installation convenient. In addition, due to the dividing groove, a space gap is provided between the plastic coil body and the metal magnetic guide frame to allow expansion. The thermal expansion of the plastic coil body will be absorbed by the gap, reducing the stress on the magnetic guide frame and improving the service life.

[0015] 2. In this application, fixing plates are fixed on both sides of the dividing groove of the magnetic guide frame. The fixing plates are connected by threaded rods. When the nuts are tightened, the magnetic guide plates on both sides of the dividing groove can be brought closer together, increasing the preload on both sides of the dividing groove. This makes the coil body more firmly clamped inside the magnetic guide frame, protecting the coil body. At the same time, when it is heated and slowly cooled, the metal magnetic guide frame recovers quickly while the coil body recovers more slowly, which may cause the clamping of the metal magnetic guide frame on the coil body to loosen. At this time, adjusting the nuts can ensure that the coil body is stably clamped. The setting of the fixing plates can also increase the heat dissipation area, assist in heat dissipation to a certain extent, and improve heat dissipation efficiency. Attached Figure Description

[0020] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: An air conditioner electromagnetic coil, such as Figures 1-2 As shown, it includes a magnetic guide frame 1 and a coil body 2. The coil body 2 is installed inside the cavity of the magnetic guide frame 1. The magnetic guide frame 1 is an integrally formed structure and has a linear dividing groove 3 that penetrates the magnetic guide frame 1 on one side. The dividing groove 3 has a mounting hole 4 in the middle. Fixing plates 7 are symmetrically arranged on the inner walls of both sides of the dividing groove 3. A threaded rod 5 passes through the fixing plates 7. A nut 6 is threadedly connected to the end of the threaded rod 5.

[0022] Its working principle is as follows: A linear dividing groove 3 is provided on one side of the magnetic guide frame 1. When the coil body 2 needs to be installed, the coil body 2 only needs to be squeezed into the inner cavity of the magnetic guide frame 1. At this time, a pre-tightening force will be generated on both sides of the dividing groove 3, which will firmly clamp the coil body 2 inside the magnetic guide frame 1, making installation convenient. Moreover, due to the dividing groove 3, a space gap is provided between the plastic coil body 2 and the metal magnetic guide frame 1 to allow expansion. The thermal expansion of the plastic coil body 2 will be absorbed by the gap, reducing the stress on the magnetic guide frame 1 and improving its service life. Fixing plates 7 are fixed on both sides of the magnetic guide frame 1 where the dividing groove 3 is provided, for fixing... Plate 7 is connected by threaded rod 5. When nut 6 is tightened, the magnetic plates on both sides of the dividing groove 3 can be brought closer together, increasing the preload on both sides of the dividing groove 3, so that the coil body 2 is more firmly clamped inside the magnetic frame 1, protecting the coil body 2. At the same time, when it is heated and slowly cooled, the metal magnetic frame 1 recovers quickly while the coil body 2 recovers more slowly, which may cause the clamping of the metal magnetic frame 1 on the coil body 2 to loosen. At this time, adjusting nut 6 can ensure that the coil body 2 is stably clamped. The setting of fixing plate 7 can also increase the heat dissipation area, assist in heat dissipation to a certain extent, and improve heat dissipation efficiency.

[0023] Specifically, the magnetic guide frame 1, the threaded rod 5, and the nut 6 are made of metal conductors.

[0024] Specifically, such as Figure 1As shown, the magnetic guide frame 1 includes two opposing magnetic guide plates, and the distance between the inner walls of the two magnetic guide plates is less than the width of the coil body 2.

[0025] Specifically, the width of the dividing groove 3 is less than 1 mm.

[0026] Specifically, the fixing plate 7 is symmetrically provided with two sets, one above the other.
