Description

Technical Field

[0001] This utility model relates to the field of solenoid coil heat dissipation technology, specifically a solenoid coil water cooling device. Background Technology

[0002] A solenoid coil is a common electromagnetic device consisting of a long cylindrical coil of wire. When an electric current passes through the coil, it generates a magnetic field. This magnetic field can move an iron rod or other magnetic material placed on its axis. Therefore, solenoids are often used to operate mechanical valves or other mechanical parts by turning on or off current.

[0003] Solenoids have a wide range of applications, including in electronic devices such as electronic pinball machines, dot matrix printers, and fuel injection systems. They can also be used as electromagnets or inductors to generate strong magnetic fields in magnetic resonance imaging (MRI) equipment. In industrial applications, solenoids are used to control fluid flow; for example, solenoids in transmissions can adjust the flow rate of hydraulic oil. The working principle of a solenoid is based on Faraday's law of electromagnetic induction, which states that a change in the magnetic field within a conductor generates an electromotive force (EMF). Solenoids are typically powered by direct current (DC) or alternating current (AC). The current flowing through the solenoid generates a magnetic field, which can be used to achieve various practical applications.

[0004] Solenoid coils are widely used in real life. In some applications, the excessive current inside the solenoid coil causes it to overheat severely. The high temperature may affect the magnetic field effect of the solenoid coil, and in severe cases, it may melt and cause equipment failure. Therefore, a water cooling device for solenoid coils is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water cooling device for solenoid coils, which has the advantages of good heat dissipation and strong practicality, and solves the problem that the large internal current of the solenoid coil may cause serious overheating, affecting the magnetic field or even melting.

[0006] To achieve the above-mentioned objectives of good heat dissipation and strong practicality, this utility model provides the following technical solution: a solenoid coil water cooling device, including an outer cylinder and a fixed cylinder threaded to the side of the outer cylinder, wherein a water cooling component is provided inside the outer cylinder and a driving component is provided on the inner side wall of the fixed cylinder;

[0007] The water-cooling assembly includes an isolation cylinder fixedly installed on the inner wall of the outer cylinder, return grooves opened on the side walls at both ends of the isolation cylinder, several fixed grooves evenly opened on the inner wall of the isolation cylinder, heat dissipation rods fixedly installed on the inner wall of the fixed grooves, an inner cylinder threaded to the inner wall of the isolation cylinder, several heat conduction grooves evenly opened on the inner cylinder, several heat conduction rods fixedly installed on the inner wall of the heat conduction grooves, and a support cylinder threaded to the side of the outer cylinder.

[0008] The drive assembly includes a drive motor fixedly installed on the inner wall of the fixed cylinder, a transmission gear fixedly installed on the outer side of the drive motor, a rotating cylinder rotatably connected to the inner wall of the fixed cylinder, a spiral blade fixedly installed on the outer side of the rotating cylinder, and a limiting flange threadedly connected to the side of the rotating cylinder.

[0009] Furthermore, the inner and outer walls of the outer cylinder are provided with staggered heat dissipation arc grooves, and both ends of the outer cylinder are provided with threaded openings. The opposite sides of the fixed cylinder and the support cylinder are respectively embedded into the threaded openings on both sides of the outer cylinder and are fixedly installed with the outer cylinder by threads.

[0010] Furthermore, the inner cylinder has an I-shaped cylindrical structure with threaded patterns on both outer ends. The inner cylinder is screwed laterally into the interior of the isolation cylinder and is fixedly installed with the isolation cylinder by threads.

[0011] Furthermore, the inner walls of both the fixing slot and the heat-conducting slot are provided with sealing gaskets that are used in conjunction with the heat sink and the heat-conducting rod, respectively.

[0012] Furthermore, the side walls of the fixed cylinder and the inner cylinder are provided with threading holes for the coil to enter and exit, and a waterproof collar is installed inside the threading holes.

[0013] Furthermore, the rotating cylinder has an L-shaped structure with one end embedded inside the fixed cylinder and its inner and outer side walls rotatably connected to the inner wall and side wall of the fixed cylinder, respectively.

[0014] Furthermore, the rotating cylinder is provided with a driven gear ring on the outer side inside the fixed cylinder, which is used in conjunction with the transmission gear. The transmission gear meshes with the driven gear ring through its teeth.

[0015] Furthermore, one end of the rotating cylinder extends laterally through the internal opening of the support cylinder and is rotatably connected to the support cylinder, and one end of the limiting flange is embedded inside the rotating cylinder and is fixedly installed to the rotating cylinder by threads.

[0016] Compared with the prior art, the present invention provides a water cooling device for a solenoid coil, which has the following beneficial effects:

[0017] 1. This solenoid coil water cooling device works by winding the solenoid coil around the surface of the heat-conducting rod on the outside of the inner cylinder, filling the gap between the outer cylinder and the rotating cylinder with cooling water, starting the drive motor, and the rotation of the drive motor drives the rotation of the driven gear ring, which in turn drives the rotating cylinder to rotate. The rotation of the rotating cylinder drives the spiral blades to continuously push the cooling water to one side. The heat-conducting rod absorbs the heat generated by the solenoid coil and transfers it to the cooling water. After being pushed by the spiral blades, the cooling water enters the space between the outer cylinder and the isolation cylinder through the return groove on one side of the isolation cylinder.

[0018] 2. This solenoid coil water cooling device continuously pushes the cooling water through the spiral blades to form a reflux in the space between the inner cylinder and the rotating cylinder, and between the outer cylinder and the isolation cylinder. The heated cooling water reaches the heat dissipation arc groove on the inner wall of the outer cylinder. Since the inner wall of the outer cylinder is thinner at the location of the heat dissipation arc groove, the heat is dissipated into the air outside the outer cylinder through the heat dissipation arc groove. The cooled water returns to the space between the inner cylinder and the rotating cylinder through the return groove on the other side of the isolation cylinder, and absorbs the heat generated by the solenoid coil again, thereby achieving the purpose of cooling. This solves the problem that the large internal current of the solenoid coil may cause serious overheating, affecting the magnetic field or even melting. Attached Figure Description

[0029] The inner and outer walls of the outer cylinder 1 are provided with staggered heat dissipation arc grooves 309. Both ends of the outer cylinder 1 are provided with threaded openings 310. The opposite sides of the fixed cylinder 2 and the support cylinder 308 are respectively embedded into the threaded openings 310 on both sides of the outer cylinder 1 and are fixedly installed with the outer cylinder 1 by threads.

[0030] The inner cylinder 305 has an I-shaped cylindrical structure and threaded patterns on the outer sides of both ends. The inner cylinder 305 is screwed laterally into the interior of the isolation cylinder 301 and is fixedly installed with the isolation cylinder 301 by threads.

[0031] Both the fixed slot 303 and the heat conduction slot 306 have sealing gaskets on their inner sidewalls for use with heat sink 304 and heat conduction rod 307, respectively.

[0032] The side walls of the fixed cylinder 2 and the inner cylinder 305 are provided with threading holes 311 for the coil to enter and exit, and a waterproof collar is installed inside the threading holes 311.

[0033] A waterproof collar is installed inside the wire hole 311 to wrap the solenoid coil and prevent the cooling water inside the device from affecting the normal operation of the solenoid coil.

[0034] In this embodiment, the drive assembly 4 includes a drive motor 401 fixedly installed on the inner wall of the fixed cylinder 2, a transmission gear 402 fixedly installed on the outer side of the drive motor 401, a rotating cylinder 403 rotatably connected to the inner wall of the fixed cylinder 2, a spiral blade 404 fixedly installed on the outer side of the rotating cylinder 403, and a limiting flange 405 threadedly connected to the side of the rotating cylinder 403.

[0035] The rotating cylinder 403 has an L-shaped structure and one end is embedded inside the fixed cylinder 2. Its inner and outer side walls are rotatably connected to the inner wall and side wall of the fixed cylinder 2, respectively.

[0036] The rotating cylinder 403 is located on the outer side inside the fixed cylinder 2 and is equipped with a driven gear ring 406 that works with the transmission gear 402. The transmission gear 402 meshes with the driven gear ring 406 through its teeth.

The rotation of the drive motor 401 drives the rotation of the driven gear ring 406, which in turn drives the rotating cylinder 403 to rotate. The rotation of the rotating cylinder 403 drives the spiral blade 404 to continuously push the cooling water to one side. The heat-conducting rod 307 absorbs the heat generated by the solenoid coil and transfers it to the cooling water. After being pushed by the spiral blade 404, the cooling water enters the space between the outer cylinder 1 and the isolation cylinder 301 through the return groove 302 on one side of the isolation cylinder 301. The cooling water carrying heat reaches the heat dissipation arc groove 309 on the inner wall of the outer cylinder 1. Since the inner wall of the outer cylinder 1 is thinner at the position of the heat dissipation arc groove 309, the heat is dissipated into the air outside the outer cylinder 1 through the heat dissipation arc groove 309, thereby achieving the purpose of cooling.
