Description

Technical Field

[0001] The invention relates to the technical field of electrical components, in particular to a large-inductance laminated low-temperature co-fired ceramic inductor and a design method thereof. Background Art

[0002] The high-inductance multilayer low-temperature co-fired ceramic inductor is a type of inductor that works based on the principle of electromagnetic induction. When current passes through the coil inside it, a magnetic field is generated around the coil, and this magnetic field in turn hinders the change of current, thus reflecting the characteristics of inductance. Unlike ordinary inductors, it adopts a multilayer structure and is made using low-temperature co-fired ceramic (LTCC) technology, and can achieve a large inductance to meet the needs of specific circuits for high inductance values.

[0003] After searching, Chinese patent publication number CN211907144U discloses a laminated ceramic inductor, including a laminated inductor, a shell is provided on the upper outer side of the laminated inductor, a plurality of anti-slip grooves are respectively provided on the two side walls of the shell, and a heat dissipation mechanism is provided on the upper inner side of the shell. The utility model discloses a laminated ceramic inductor, which provides a detachable heat-conducting frame on its non-magnetic ceramic and cooperates with the heat dissipation mechanism on the upper part of its shell, so that the shell can protect the inductor and also have the function of heat dissipation, which can effectively prevent the inductor from not being able to discharge heat when the current is unstable. During use, the patent mostly uses a heat-conducting layer to dissipate the heat generated by its internal coil. Passive heat dissipation will affect its heat dissipation effect, resulting in the inability to quickly discharge the internal heat, which easily causes the inductor to burn out. In addition, the patent protects the inductor by frictionally fixing the rubber pad with the external electrode. The external electrode is an important part for connecting with the external circuit. The setting of the rubber pad will not only affect the connection of the external circuit, but also wear the external electrode. In view of this, we propose a large-inductance laminated low-temperature co-fired ceramic inductor and a design method thereof. Summary of the invention

[0015] It can be seen from the above technical solutions that the large-inductance multilayer low-temperature co-fired ceramic inductor and the design method thereof provided in the embodiments of this specification have at least the following beneficial effects: (1) The present invention achieves the effects of auxiliary heat dissipation, buffer protection and clamping positioning on both sides of the device body through the clamping protection device and the hollow heat sink. The cold air circulation cooling device is used to generate cold air and supply the cold air to the inside of the hollow heat sink through the connecting pipe, the hard pipe and the connecting cap, thereby realizing rapid cooling of the hollow heat sink.

At the same time, during the heat dissipation, buffering, positioning protection and easy disassembly of the device body, the normal operation of the external electrode will not be affected.

[0018] (4) The present invention provides a clamping protection device, which drives the upper clamping seat and the lower clamping seat on the bidirectional threaded rod to move away from or towards each other by rotating the handle, and then adjusts the gap between the upper clamping seat and the lower clamping seat to clamp or not clamp the device body, thereby achieving the purpose of facilitating installation and disassembly.

[0019] (5) The present invention provides an airflow blowing device, and utilizes the protective rubber ball inside the device to achieve the effect of buffering, protecting and positioning one side of the device body. Combined with the squeezing of the baffle plate by the airflow passing through the drainage groove, the flow chuck on the sliding shaft of the passive pressure plate drives the protective rubber ball to squeeze the device body. During the squeezing, the gas inside the protective rubber ball is discharged toward the surface of the device body through the flow chuck. The discharged gas has the effect of air cooling and soot blowing on the surface of the device body, thereby utilizing the power of the cold air circulation to achieve secondary cooling of the surface of the device body, thereby improving the cooling effect on the device body, and also having the function of automatic cleaning of the device body.

[0026] Furthermore, the cold air circulation cooling device 10 includes a refrigeration base 101, one side of the refrigeration base 101 is connected to the end of the connecting pipe 9 through a multi-head connecting device 11, the length of the connecting pipe 9 is not limited, and the installation of the refrigeration base 101 is also positioned according to actual conditions. The refrigeration base 101 is arranged outside the device body 1, so that it is convenient for the operator to distribute it according to the installation position of the device body 1 and the installation space in the transformer, thereby improving the applicability of the overall technical solution. Two circular holes (such as Figure 7As shown), they are respectively an air inlet and an air outlet, the number of the multi-connection devices 11 is set to two, and the two multi-connection devices 11 are respectively connected to the air inlet and the air outlet (as shown Figure 7 As shown), the corresponding connecting pipe 9 on the one-way air inlet connecting spiral tube 5 corresponds to the multi-head connecting device 11 at the air outlet, and the corresponding connecting pipe 9 on the one-way air outlet connecting spiral tube 6 corresponds to the multi-head connecting device 11 at the air inlet (combined with Figure 1 , Figure 7 and Figure 5 As shown in the figure, an active motor 102 is installed on the refrigeration base 101, and a crank rod 103 is clamped on the output shaft of the active motor 102.

A semiconductor refrigerator is installed on one side of the pneumatic plate 106 inside the refrigeration base 101. 107, the semiconductor refrigerator 107 cools the gas in the refrigeration base 101, the output shaft of the active motor 102 drives the crankshaft 103 to rotate, and the crankshaft 103 drives the limit base 104 slidably connected at its end to move back and forth during the rotation, and the limit base 104 drives the air pressure plate 106 to move as a piston in the refrigeration base 101 through the connecting rod 105, so as to achieve the effect of sucking and squeezing the gas in the refrigeration base 101, and the air pressure plate 106 is connected to the connecting pipe 9 through two multi-head connecting devices 11 during the movement, so as to achieve the effect of one-way circulation of cold air to the hollow heat sink 4.

[0027] Furthermore, the end of the connecting pipe 9 away from the hard pipe 8 is fixedly connected with a convex head 91, and the multi-head connecting device 11 includes a transfer seat 111, one side of the transfer seat 111 is fixedly connected to one side of the refrigeration base 101, and the other side of the transfer seat 111 is provided with a plurality of slots 112, and the convex head 91 is inserted into the interior of any one of the plurality of slots 112, and the interior of the transfer seat 111 is fixedly connected with a plug rod 113 (such as Fig.10As shown in the figure, a blocking valve 114 is slidably connected to the plug rod 113, and a spring is fixedly connected between the surface of the blocking valve 114 and the inner wall of the adapter seat 111.

The upper magnetic clamping seat 115 and the lower magnetic clamping seat 116 are both clamped with the surface of the convex head 91. The adapter 111 transfers the cold air from the connecting pipe 9 to the hard pipe 8 through the snap-on convex head 91. The hard pipe 8 delivers the cold air to the hollow heat sink 4 through the connection between the connecting cap 7 and the one-way air inlet connecting spiral tube 5. The cold air flows from one side of the hollow heat sink 4 to the other side through the drainage groove 43. During the circulation, the hollow heat sink 4 is actively dissipated and quickly cooled. The gas is delivered to the adapter 111 at the air inlet through the one-way air outlet connecting spiral tube 6 connected to the other side and the connecting cap 7, hard tube 8, connecting pipe 9 and convex head 91 thereon.

The user can rotate any one of the multiple turning handles 38, and the turning handle 38 drives the gear 36 there to achieve the effect of driving the bidirectional threaded rod 32 to rotate. Since the four gears 36 are transmitted through the toothed belt 37, the effect of synchronous rotation of the four gears 36 can be achieved by rotating one turning handle 38. Correspondingly, the four bidirectional threaded rods 32 are also rotated and adjusted at the same time. When the bidirectional threaded rod 32 rotates, the upper clamping seat 31 and the lower clamping seat 33 are driven to move away from or towards each other through the threads on the upper clamping seat 31, and then the device body 1 is clamped or not by adjusting the gap between the upper clamping seat 31 and the lower clamping seat 33, thereby achieving the purpose of facilitating installation and disassembly.

Since the protective rubber ball 425 is elastic and is in contact with the device The baffle plate 422 is in contact with the body 1, so the baffle plate 422 is supported and contacted by the protective rubber ball 425 on the body 1, and a blocking effect will be generated inside the drainage groove 43. When the airflow passes through the drainage groove 43, the airflow force will squeeze the baffle plate 422, and the baffle plate 422 moves downward under the influence of the inclined surface on it. After the baffle plate 422 moves downward, it drives the flow chuck 424 on the sliding shaft 423 to be squeezed downward through the passive pressure plate 421, and the flow chuck 424 drives the protective rubber ball 425 to be squeezed toward the body 1. During the squeezing, the internal gas of the protective rubber ball 425 is discharged toward the surface of the body 1 through the flow chuck 424. The discharged gas has the effect of air cooling and soot blowing on the surface of the body 1, thereby utilizing the power of the cold air circulation to achieve secondary cooling of the surface of the body 1, thereby improving the cooling effect on the body 1, and also having the function of automatic cleaning of the body 1. At the same time, since the protective rubber ball 425 positions the device body 1 under normal conditions, when the device body 1 vibrates as a whole, the protective rubber ball 425 can, on the one hand, provide buffering protection for the device body 1, and on the other hand, it can also use the airflow generated by extrusion to act on the surface of the device body 1, thereby achieving the cooling and cleaning effects again.

[0030] A design method for a large-inductance multilayer low-temperature co-fired ceramic inductor, comprising: Step A: protection, by rotating any one of the multiple rotating handles 38, the bidirectional threaded rod 32 on the gear 36 is driven to rotate, and the bidirectional threaded rod 32 drives the upper clamping seat 31 and the lower clamping seat 33 to move relatively, completing the clamping protection work of the entire device body 1, thereby achieving the effect of buffering protection and positioning clamping of the device body 1, and at the same time will not affect the normal work of the external electrode 2; Step B: passive heat dissipation, the hollow heat dissipation plate 4 absorbs the heat on the device body 1 and dissipates heat through a plurality of heat sinks 41, thereby improving the overall heat dissipation effect of the device body 1; Step C: Active heat dissipation, including the following steps: C1, cooling, starting the semiconductor refrigerator 107, the semiconductor refrigerator 107 cools the gas in the cooling base 101, thereby using the cold air to achieve rapid cooling of the device body 1; C2, conveying, start the active motor 102, the output shaft of the active motor 102 controls the limit base 104 to move back and forth linearly through the reciprocating rotation of the bent rod 103, the limit base 104 drives the air pressure plate 106 to move the piston in the refrigeration base 101 through the connecting rod 105, the air pressure plate 106 squeezes the cold air in the refrigeration base 101 to the adapter 111 at the air outlet, the adapter 111 transfers the cold air from the connecting pipe 9 to the hard pipe 8 through the clamping convex head 91, the hard pipe 8 conveys the cold air to the hollow heat sink 4 through the connection cap 7 and the one-way air inlet connecting spiral tube 5, and the cold air acts on the hollow heat sink 4 to achieve rapid cooling of the device body 1; C3, circulation, cold air flows from one side of the hollow heat sink 4 to the other side through the drainage groove 43, and active heat dissipation and rapid cooling of the hollow heat sink 4 are achieved during the circulation, and the gas is transported to the adapter 111 at the air inlet through the one-way air outlet connecting spiral tube 6 connected to the other side and the connecting cap 7, hard tube 8, connecting tube 9 and protruding head 91 thereon, and the gas is transported to the refrigeration base 101 again through the adapter 111 for cooling, so as to achieve the effect of cold air circulation, and then ensure continuous auxiliary cooling of the device body 1, and solve the problem of poor heat dissipation effect of the existing inductor.

[0031] When the large-inductance laminated low-temperature co-fired ceramic inductor and the design method thereof are used, the hollow heat sink 4 and the airflow blowing device 42 on one side thereof are used to provide buffer protection and positioning clamping for one side of the device body 1, while the protective bottom plate 310 in the lower clamp seat 35 is used to provide buffer protection and positioning clamping for the other side of the device body 1. The user can rotate any one of the multiple rotating handles 38, and the rotating handle 38 drives the gear 36 there to achieve the effect of driving the bidirectional threaded rod 32 to rotate. Since the four gears 36 are driven by the toothed belt 37, the transmission is performed through By rotating a handle 38, the four gears 36 can be rotated synchronously. Accordingly, the four bidirectional threaded rods 32 are also rotated and adjusted at the same time. When the bidirectional threaded rods 32 rotate, the upper clamping seat 31 and the lower clamping seat 33 are driven to move away from or close to each other through the threads on the upper clamping seat 31 and the lower clamping seat 33. Then, the clamping of the device body 1 is achieved by adjusting the gap between the upper clamping seat 31 and the lower clamping seat 33, thereby achieving the purpose of facilitating installation and disassembly. At the same time, the adjustability of the upper clamping seat 31 and the lower clamping seat 33 can also achieve the purpose of clamping and protecting the device body 1 of different thicknesses. When the hollow heat sink 4 performs buffer protection and positioning clamping on one side of the device body 1, since the protective rubber balls 425 are distributed in a dot array on the hollow heat sink 4, when the device body 1 generates heat during normal operation, the heat energy can be transferred to the hollow heat sink 4 through the transfer of air, and the hollow heat sink 4 is set as a heat dissipation material, which can quickly dissipate the heat through the heat sink 41, thereby improving the overall heat dissipation effect of the device body 1.

[0032] At the same time, when the temperature of the device body 1 is high, by starting the semiconductor refrigerator 107 and the active motor 102, the semiconductor refrigerator 107 cools the gas in the refrigeration base 101, and the output shaft of the active motor 102 drives the crankshaft 103 to rotate. During the rotation, the crankshaft 103 drives the limit base 104 slidably connected to its end to perform reciprocating linear movement. The limit base 104 drives the air pressure plate 106 to perform piston movement in the refrigeration base 101 through the connecting rod 105. The air pressure plate 106 squeezes the cold air in the refrigeration base 101 to the adapter 111 at the air outlet. The adapter 111 transfers the cold air from the connecting pipe 9 to the hard pipe 8 through the clamping convex head 91. The hard pipe 8 delivers the cold air to the hollow heat sink 4 through the docking of the connecting cap 7 and the one-way air inlet connecting spiral tube 5. The cold air flows from one side of the hollow heat sink 4 to the other side through the drainage groove 43, and the active heat dissipation and rapid cooling of the hollow heat sink 4 are realized during the circulation, and the gas is transported to the adapter 111 at the air inlet through the one-way air outlet connecting spiral tube 6 connected to the other side and the connecting cap 7, hard tube 8, connecting tube 9 and protruding head 91 thereon, and the gas is transported to the refrigeration base 101 again through the adapter 111 for cooling, so as to achieve the effect of automatically and quickly dissipating the heat of the device body 1, and the cold air can circulate, thereby ensuring the continuous auxiliary cooling of the device body 1, solving the problem of poor heat dissipation effect of the existing inductor, and at the same time, during the heat dissipation, buffering, positioning protection and easy disassembly of the device body 1, it will not affect the normal operation of the external electrode 2.

[0033] Furthermore, when the airflow passes through the drainage groove 43, the airflow squeezes the baffle plate 422 to make it move downward. After the baffle plate 422 moves downward, it drives the flow chuck 424 on the sliding shaft 423 to be squeezed downward through the passive pressure plate 421. The flow chuck 424 drives the protective rubber ball 425 to be squeezed toward the device body 1. During the squeezing, the internal gas of the protective rubber ball 425 is discharged toward the surface of the device body 1 through the flow chuck 424. The discharged gas has the effect of air cooling and soot blowing on the surface of the device body 1, thereby utilizing the power of the cold air circulation to achieve secondary cooling of the surface of the device body 1, thereby improving the cooling effect on the device body 1 and also having the function of automatic cleaning of the device body 1.
