Description

Technical Field

[0001] The utility model relates to the technical field of compressor clutch coils, in particular to a clutch coil for an automobile air-conditioning compressor. Background Art

[0002] The clutch coil of the car air conditioner is part of the air conditioner compressor. Its main function is to control the start and stop of the compressor. When the car air conditioner is turned on, the clutch coil of the air conditioner system will be activated by the current, attracting the clutch plate to combine with the drive plate of the compressor, so that the compressor starts to work; conversely, when you turn off the air conditioner, the clutch coil is no longer energized, the clutch plate will separate, and the compressor will stop running.

[0003] Due to advancements in today's manufacturing industry, existing compressor clutch coils are generally made of advanced composite materials or special alloys. These materials offer improved thermal stability and deformation resistance, maintaining structural stability and precision under various temperature conditions. High-precision processing equipment and techniques, such as CNC machining, ensure that the dimensional accuracy and surface finish of the coil housing meet high standards. High-precision machining helps improve the matching accuracy between the coil housing and the coil, reducing energy loss.

[0004] However, in the prior art, the coil shell is generally an integrated structure, and a heat dissipation structure is rarely provided, which results in poor heat dissipation performance of the coil. Excessive temperature will affect the overall working performance. In addition, before the existing coil is filled with resin material, the coil located inside the coil shell is generally placed directly into it and then filled with resin. However, this may cause the coil to be placed unsteadily, affecting the electromagnetic field and thus affecting the working performance of the coil. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing coil housing generally does not have a heat dissipation structure, and the electromagnetic coil inside the housing is easily placed unstable, which affects the electromagnetic field strength.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a clutch coil of an automobile air-conditioning compressor, including a coil housing, a plurality of limit plates fixed on the inside of the coil housing, a limit groove and an installation groove provided on one side of the limit plate, a fixing plate inserted in the installation groove, an electromagnetic coil placed in the limit groove, a plurality of heat sinks fixed on the outside of the coil housing, and a heat conductive ring fixed on the outside of the heat sink.

[0007] As a further solution of the present invention: support ring ribs are fixed in the middle of a plurality of heat sinks to fix the positions of the plurality of heat sinks.

[0008] As a further solution of the present invention, the interior of the coil housing is filled with resin material, which can achieve the effects of fixing and insulation.

[0009] As a further solution of the present invention: a wiring terminal is fixed on one side of the coil housing, the wiring terminal is electrically connected to an electric wire and a connector, and the wiring terminal is electrically connected to the electromagnetic coil.

[0010] As a further solution of the present invention: there are four limiting plates in total, which are evenly fixed on the inner side of the coil housing, thereby ensuring stable installation of the electromagnetic coil.

[0011] As a further solution of the present invention, the filling depth of the resin material is smaller than the inner depth of the coil housing, so as to reserve space for the thermal expansion and contraction of the resin.

[0012] Compared with the prior art, the advantages of the present invention are as follows: 1. The present invention adds a heat sink structure, which can transfer the heat inside the coil housing when the electromagnetic coil is working, thereby preventing the electromagnetic coil from overheating and affecting normal operation;

[0013] 2. A limit plate and a fixed plate structure are added to limit the position of the electromagnetic coil when installing it, so that it can maintain a stable installation state before filling the resin material, thereby ensuring the stability of the electromagnetic field.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a technical solution for solving the existing problems raised in the background technology.

[0024] Combined with attachment Figure 1-5 , it can be seen that the device includes a coil housing 1, four limiting plates 2 are fixed to the inner side of the coil housing 1, and are evenly fixed to the inner side of the coil housing 1 to ensure the stable installation of the electromagnetic coil 4. A limiting groove 2.1 and an installation groove are provided on one side of the limiting plate 2. A fixing plate 3 is inserted into the installation groove, and the electromagnetic coil 4 is placed in the limiting groove 2.1. A plurality of heat sinks 5 are fixed to the outside of the coil housing 1, and a heat conducting ring 6 is fixed to the outside of the heat sink 5;

[0025] A supporting ring rib 7 is fixed in the middle of several heat sinks 5, which can fix the position of several heat sinks 5; the inside of the coil housing 1 is filled with resin material 8, which can play a fixing and insulation effect; a terminal 9 is fixed on one side of the coil housing 1, and the terminal 9 is electrically connected to the wire 10 and the connector 11, and the terminal 9 is electrically connected to the electromagnetic coil 4; the filling depth of the resin material 8 is less than the depth of the inner side of the coil housing 1, which can reserve space for the thermal expansion and contraction of the resin.

[0026] The working principle of the present application is as follows: when installing the coil, the electromagnetic coil 4 is first placed in the limiting groove 2.1 on one side of the limiting plate 2 in the coil housing 1, and then connected to the terminal 9. The position of the electromagnetic coil 4 is then limited by the fixing plate 3. After that, the resin material 8 can be filled to stabilize the position of the electromagnetic coil 4 to increase wear resistance.

[0027] When the clutch coil is running, the electromagnetic coil 4 generates heat, which is transferred through the coil housing 1 to the heat sinks 5 and then to the heat conducting ring 6 to dissipate the heat to the external environment, ensuring that the electromagnetic coil 4 can operate at a suitable temperature.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
