Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an inductor frame and an inductor. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. An inductor is generally composed of a skeleton, windings, a shielding cover, packaging materials, a magnetic core or an iron core, etc.

[0003] At present, a Chinese patent discloses a multi-effect heat dissipation inductor (publication number CN208027865U). Through the cooperation of the heat collecting plate, the heat transfer rod, the cold water pipe, the power supply, the switch, the first conductive block of the water pump and the second conductive block, the first conductive block, the second conductive block, the power supply and the switch are connected in sequence to form a loop, so that the water pump starts to work, the water starts to circulate in the cold water pipe, the temperature of the heat transfer rod drops, and the cooling of the heat collecting plate drives the inductor to dissipate heat.

[0004] Since the above device uses structures such as a water pump and a cold water pipe to dissipate heat from the inductor, it is necessary to leave additional space inside and outside the inductor for placing additional structures such as the water pump and the cold water pipe. This not only increases the volume of the inductor itself, but also external structures such as the water pump increase the space occupied by the inductor, resulting in low practicality.

[0005] Therefore, an inductor frame and an inductor are proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an inductor frame and an inductor in order to solve the above problems, thereby improving the problems that the existing inductors with heat dissipation function are large in size and occupy a large space and have low practicality.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions. An inductor skeleton comprises: a winding skeleton; a liquid conducting channel is provided inside the winding skeleton; two heat sinks are fixedly connected to the surface of the winding skeleton, and one end of the heat sink is communicated with the liquid conducting channel; the heat sink comprises a heat conducting pipe fixedly connected to the surface of the winding skeleton, a liquid wick communicated with the liquid conducting channel is arranged inside the heat conducting pipe, the liquid conducting channel and the liquid wick are both filled with liquid ether, a flow guiding mechanism is installed inside the liquid wick, the heat sink cooperates with the liquid conducting channel and the liquid ether to circulate and reduce the operating temperature of the coil, thereby achieving the purpose of reducing the operating heat of the coil, and compared with the existing heat dissipation structure, the heat sink is small in size and can be placed in the gap between the shielding cover and the winding skeleton, and does not increase the overall volume and occupied space of the inductor, thereby improving the practicality of the inductor.

[0008] Preferably, the liquid guiding channel is serpentine in shape, and the highest point of the liquid guiding channel is connected to the lowest point of the liquid wick, which not only increases the storage capacity of liquid ether, but also increases the indirect contact area between the liquid ether and the coil, thereby improving the heat dissipation effect of the coil.

[0009] Preferably, the guide mechanism includes an annular sleeve fixedly connected to the interior of the absorbent core, the interior of the annular sleeve is slidably connected with a connecting tube, the top and bottom ends of the connecting tube both extend to the outside of the annular sleeve, the bottom of the connecting tube is fixedly connected with a floating block in contact with liquid ether, the top of the connecting tube is fixedly connected with a mounting bar, the top of the mounting bar is fixedly connected with elastic wires that are evenly distributed and in contact with the inner top wall of the absorbent core, the guide mechanism can rub the liquid ether on the inner top wall of the absorbent core under the impact of the rising gaseous ether, which can reduce the adhesion between the liquid ether and the absorbent core, so that the liquid ether can fall more quickly, so that more gaseous ether can contact with the inner top wall of the absorbent core, thereby improving the cooling effect of the gaseous ether.

[0010] Preferably, the elastic wire is a nylon material component, and the ring sleeve, connecting pipe, floating block and mounting strip are all polytetrafluoroethylene material components, which can improve the corrosion resistance of the overall guide mechanism and extend the service life of the overall guide mechanism.

[0011] Preferably, the distance between the ring sleeve and the floating block is smaller than the distance between the mounting strip and the inner top wall of the absorbent core, which can prevent the mounting strip from scratching the inner top wall of the absorbent core, thereby reducing the occurrence of damage to the inner top wall of the absorbent core, thereby achieving the purpose of extending the service life of the heat dissipation device.

[0012] Preferably, the corners of the floating block are rounded, which can reduce the probability of the floating block scratching the inner wall of the absorbent core, further reducing the occurrence of damage to the inner top wall of the absorbent core, thereby achieving the purpose of extending the service life of the heat dissipation device.

[0013] An inductor comprises a winding frame, a coil, a magnetic ring, a base and a shielding cover, wherein the coil is wound on the surface of the winding frame, the magnetic ring is installed on the surface of the winding frame, the base is clamped on the bottom of the magnetic ring, the two ends of the coil pass through the outside of the base, the shielding cover is fixedly connected to the surface of the base, and the winding frame, the coil and the magnetic ring are all arranged inside the shielding cover; the surface of the shielding cover is provided with evenly distributed heat dissipation holes, and the shielding cover with heat dissipation holes is used. The heat dissipation holes can allow air inside and outside the shielding cover to circulate, so that the circulating air takes away the heat dissipated inside the shielding cover, thereby achieving a good cooling effect.

[0014] Preferably, a dustproof net is embedded in the heat dissipation hole, and the size of the dustproof net matches the size of the heat dissipation hole. The dustproof net can prevent dust from entering the interior of the shielding cover, which not only keeps the interior of the shielding cover clean, but also reduces the interference of dust on the heat dissipation of the internal structure of the shielding cover, so as to achieve the purpose of ensuring the heat dissipation effect.

[0015] The beneficial effects of the utility model are:

[0016] The heat dissipation device cooperates with the liquid guide channel and the liquid ether to circulate and reduce the operating temperature of the coil, thereby achieving the purpose of reducing the operating heat of the coil. Compared with the existing heat dissipation structure, the heat dissipation device is small in size and can be placed in the gap between the shielding cover and the winding frame, and does not increase the overall volume and occupied space of the inductor, thereby improving the practicality of the inductor.

[0017] The flow guiding mechanism can rub the liquid ether on the inner top wall of the absorbent core under the impact of the rising gaseous ether, which can reduce the adhesion between the liquid ether and the absorbent core, so that the liquid ether can fall more quickly, so that more gaseous ether can contact with the inner top wall of the absorbent core, thereby improving the cooling effect of the gaseous ether;

[0018] A shielding cover with heat dissipation holes is used, and the heat dissipation holes can allow air to circulate inside and outside the shielding cover, so that the circulating air takes away the heat dissipated inside the shielding cover, thereby achieving a good cooling effect.

DETAILED DESCRIPTION

[0025] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] When implementing: Figure 1-5 As shown, an inductor skeleton comprises: a winding skeleton 1; a liquid conducting channel 11 is provided inside the winding skeleton 1; two heat sinks 2 are fixedly connected to the surface of the winding skeleton 1, and one end of the heat sink 2 is communicated with the liquid conducting channel 11; the heat sink 2 comprises a heat conducting pipe 21 fixedly connected to the surface of the winding skeleton 1, a liquid wick 211 communicated with the liquid conducting channel 11 is arranged inside the heat conducting pipe 21, the liquid conducting channel 11 and the liquid wick 211 are both filled with liquid ether, and a flow guiding mechanism 22 is installed inside the liquid wick 211. When producing the sensor skeleton, the liquid conducting channel 11 inside the winding skeleton 1 is first opened, and then the heat conducting pipe 21 with the flow guiding mechanism 22 is welded to the surface of the winding skeleton 1, and the liquid wick 211 is connected with the liquid conducting channel 11, and then the inside of the heat conducting pipe 21 and the liquid conducting channel 11 is evacuated to a negative pressure state. When the negative pressure value reaches a specified value, a corresponding volume of liquid ether is poured into the heat conducting pipe 21 and the liquid conducting channel 11, and finally the heat conducting pipe 21 is closed; the liquid conducting channel 11 is serpentine in shape, and the highest point of the liquid conducting channel 11 is connected with the lowest point of the liquid wick 211.

[0027] like Figure 5 As shown, the flow guiding mechanism 22 includes a ring sleeve 221 fixedly connected to the inside of the liquid absorbent core 211, a connecting tube 222 is slidably connected to the inside of the ring sleeve 221, both the top and bottom ends of the connecting tube 222 penetrate to the outside of the ring sleeve 221, a floating block 223 in contact with liquid ether is fixedly connected to the bottom of the connecting tube 222, a mounting bar 224 is fixedly connected to the top of the connecting tube 222, and elastic wires 225 evenly distributed and in contact with the inner top wall of the liquid absorbent core 211 are fixedly connected to the top of the mounting bar 224; the elastic wires 225 are made of nylon material, the ring sleeve 221, the connecting tube 222, the floating block 223, and the mounting bar 224 are all made of polytetrafluoroethylene material; the distance between the ring sleeve 221 and the floating block 223 is smaller than the distance between the mounting bar 224 and the inner top wall of the liquid absorbent core 211; the corners of the floating block 223 are rounded;

[0028] When the gaseous ether flows into the interior of the absorbent core 211, the gaseous ether inevitably impacts the floating block 223 during the rising process, and the floating block 223 drives the connecting tube 222 to rise and fall, and the connecting tube 222 drives the mounting bar 224 to rise and fall, and the mounting bar 224 drives the elastic wire 225 to wipe the inner top wall of the absorbent core 211. At this time, the liquid ether retained on the inner top wall of the absorbent core 211 is shaken, which can reduce the adhesion between the liquid ether and the absorbent core 211, so that the liquid ether can fall more quickly, so that more gaseous ether can contact the inner top wall of the absorbent core 211, thereby improving the cooling effect of the gaseous ether.

[0029] like Figure 1-4 As shown, an inductor includes a winding frame 1, a coil 3, a magnetic coil 4, a base 5 and a shielding cover 6, the coil 3 is wound on the surface of the winding frame 1, the magnetic coil 4 is installed on the surface of the winding frame 1, the base 5 is clamped on the bottom of the magnetic coil 4, the two ends of the coil 3 pass through the outside of the base 5, the shielding cover 6 is fixedly connected to the surface of the base 5, and the winding frame 1, the coil 3 and the magnetic coil 4 are all arranged inside the shielding cover 6; the surface of the shielding cover 6 is provided with evenly distributed heat dissipation holes 61, the heat dissipation holes 61 can allow air to circulate inside and outside the shielding cover 6, so that the circulating air takes away the heat dissipated inside the shielding cover 6, thereby achieving a good cooling effect; a dustproof net 7 is embedded and installed inside the heat dissipation hole 61, the size of the dustproof net 7 matches the size of the heat dissipation hole 61, and the dustproof net 7 can prevent dust from entering the inside of the shielding cover 6, which can not only keep the inside of the shielding cover 6 clean, but also reduce the interference of dust on the heat dissipation of the internal structure of the shielding cover 6, so as to achieve the purpose of ensuring the heat dissipation effect.

[0030] When the utility model is in use, when the coil 3 is heated, the heat of the coil 3 is transferred to the winding frame 1, and the winding frame 1 transfers the heat to the liquid ether through the liquid guide channel 11. When the liquid ether reaches the boiling point, it evaporates and rises rapidly. The gaseous ether enters the liquid wick 211 along the liquid guide channel 11 and is retained at the upper end of the liquid wick 211. At this time, the liquid wick 211 cooperates with the heat conduction pipe 21 to quickly conduct the heat of the gaseous ether. At this time, the gaseous ether is cooled and condensed into a liquid state and flows back to the lower end of the liquid wick 211, so that the liquid ether is re-blended together, and the temperature of the liquid ether inside the liquid guide channel 11 is reduced, so that the hot ether can always absorb the heat dissipated by the coil 3, thereby achieving the purpose of reducing the running heat of the coil 3. Compared with the existing heat dissipation structure, the heat dissipation device 2 is small in size and can be placed in the gap between the shielding cover 6 and the winding frame 1, and will not increase the overall volume and occupied space of the inductor, thereby improving the practicality of the inductor.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
