Description

Technical Field

[0001] The present invention relates to the technical field of electronic components, and in particular to an inductor and transformer combination device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation.

[0003] The main function of the inductor in the transformer is filtering and energy storage, making the current purer.

[0004] At present, in the combination device of inductor and transformer, the heat generated is large due to the large overall power. However, if the heat dissipation effect of the combination device is to be improved, the volume of the combination device needs to be expanded to set up more heat dissipation structures and heat dissipation spaces. The higher the power, the larger the volume required. However, this will greatly reduce the space utilization of the transformer. Summary of the invention

[0005] In view of the defects existing in the prior art, the technical problem solved by the present invention is: how to improve the heat dissipation effect of the inductor and transformer combination device without increasing the volume.

[0006] To achieve the above objectives, the present invention provides an inductor and transformer combination device, comprising: The housing comprises a main housing and a bottom plate, both of which are made of copper, and an inner wall of the main housing is provided with a partition plate, the partition plate is used to separate the main housing into a first space and a second space, and the first space is located on the top of the second space; An inductor is arranged inside the first space and located on the top surface of the partition plate, and a glass fiber board is arranged between the inductor and the partition plate to insulate the inductor from the partition plate; A transformer is arranged inside the second space, and includes a bracket, a magnetic core and a winding assembly, wherein the magnetic core is arranged inside the bracket, the winding assembly is wound outside the bracket, the bracket is provided with an insulating groove, which is used to divide the bracket into left and right parts, and the support legs of the bracket are fixedly connected to the bottom plate; The glue injection layer is arranged between the inductor and the main housing, and is arranged at the periphery of the winding integration.

[0007] By adopting the above technical solution, the heat generated by the inductor can be transferred to the main shell through the partition plate at the bottom thereof, and then transferred from the main shell to the bottom plate, and then installed on the water-cooled plate through the bottom plate to achieve the effect of heat dissipation of the inductor. The heat generated by the transformer can be directly transferred to the bottom plate through the bracket to achieve the effect of heat dissipation of the transformer, and the bracket is located inside the transformer to further improve the heat dissipation effect. The partition plate, the main shell, the bottom plate, and the bracket can all be set to a material with good thermal conductivity, such as copper. Since copper has good thermal conductivity, the heat dissipation effect of the above heat conduction route is better. At the same time, the inductor, the transformer and the heat conduction structure are insulated by the designed glass fiber board and the injection layer, and the bracket is provided with an insulating groove, so that a current loop cannot be formed on the bracket. Therefore, the above heat conduction route can only conduct heat but not conduct electricity, and there is no need to set more heat dissipation structures and heat dissipation spaces to increase the heat dissipation effect. Therefore, the inductor and transformer combination device improves the heat dissipation effect of the inductor and transformer combination device without increasing the volume.

[0014] In one embodiment, the output member is disposed on the top surface of the inductor output plate, a portion of the inductor output plate is laid on the top surface of the glass fiber board, and another portion is located outside the main housing.

[0016] In one embodiment, a partition is provided between the first winding and the second winding, a high temperature tape is sleeved on the partition, and a side edge of the partition is fixed to the partition plate.

[0017] By adopting the above technical solution, the heat dissipation area of ​​the inductor is increased, the sides of the first winding and the second winding can be transferred to the partition plate through the partition, and the partition and the winding are insulated by the high-temperature tape.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0030] The inductor and transformer combination device in the embodiment of the present invention is shown in FIG. Figure 1-3As shown, the inductor and transformer combination device includes a housing 1, which includes a main housing 101 and a bottom plate 102, both of which are made of copper. The inner wall of the main housing 101 is provided with a partition plate 105, and the partition plate 105 is used to separate the main housing 101 into a first space and a second space arranged in a vertical direction; an inductor 2 is arranged inside the first space, and the inductor 2 is located on the top surface of the partition plate 105, and a glass fiber board 106 is arranged between the inductor 2 and the partition plate 105, and the glass fiber board 106 is used to insulate the inductor 2 from the partition plate 105; inside the second space A transformer 3 is provided, which includes a bracket 304, a magnetic core and a winding assembly, the magnetic core is arranged inside the bracket 304, and the winding assembly is wound outside the bracket 304. The bracket 304 is provided with an insulating groove, which is used to divide the bracket 304 into two left and right parts so that a current loop cannot be formed on the bracket 304, and the support leg 306 of the bracket 304 is fixedly connected to the bottom plate 102; a glue injection layer is provided between the inductor 2 and the main shell 101, and a glue injection layer is provided between the winding assembly and the partition plate 105, the winding assembly and the main shell 101, and the winding assembly and the bottom plate 102.

[0031] It can be seen that the heat generated by the inductor 2 of the present invention can be transferred to the main housing 101 through the partition plate 105 at the bottom thereof, and then transferred from the main housing 101 to the bottom plate 102, and then installed on the water cooling plate through the bottom plate 102, so as to achieve the heat dissipation effect of the inductor 2. The heat generated by the transformer 3 can be directly transferred to the bottom plate 102 through the bracket 304, so as to achieve the heat dissipation effect of the transformer 3. Since copper has good thermal conductivity, the heat dissipation effect of the above heat conduction route is better, and the bracket 304 is located inside the transformer 3, which further improves the heat dissipation effect. At the same time, a glass fiber board 106 is arranged between the inductor 2 and the partition plate 105, a glue injection layer is arranged between the inductor 2 and the main shell 101, and a glue injection layer is arranged between the winding integration and the partition plate 105, the winding integration and the main shell 101, and the winding integration and the bottom plate 102. In addition, an insulating groove is provided on the bracket 304 to form a short circuit on the bracket 304. Therefore, the above-mentioned heat conduction route can only conduct heat but not conduct electricity, and there is no need to set more heat dissipation structures and heat dissipation spaces to increase the heat dissipation effect. Therefore, the inductor and transformer combination device improves the heat dissipation effect of the inductor and transformer combination device without increasing the volume.

[0032] Preferably, see Figure 2 As shown, the insulating groove is opened on the top surface of the bracket 304, and an epoxy block 305 is embedded in the insulating groove. The shape of the epoxy block 305 can be changed according to the shape of the insulating groove, but it must meet the requirement that a current loop cannot be formed on the bracket 304.

[0033] Specifically, the gap of the insulating groove is filled by the epoxy block 305, thereby avoiding the problem that when the winding is wound on the bracket 304 due to the insulating groove on the bracket 304, the winding here will be recessed into the insulating groove, thereby affecting the actual power of the transformer 3.

[0034] Preferably, see Figure 4 As shown, the inductor 2 includes a magnetic block 203, a pad 204, a first magnetic column 205, a second magnetic column 206, a first winding 207 and a second winding 208. The first magnetic column 205 and the second magnetic column 206 are arranged parallel to each other on the top of the partition plate 105, and the pad 204 is fixed at both ends of the two, and the magnetic block 203 is fixed on the other side of the pad 204. The first winding 207 is wound on the first magnetic column 205, and the second winding 208 is wound on the second magnetic column 206.

[0035] Specifically, the inductor 2 is designed as two groups. The first winding 207 is first wound around the first magnetic column 205, and the second winding 208 is wound around the second magnetic column 206. The first magnetic column 205 and the second magnetic column 206 are then placed in parallel. The two ends of the magnetic columns are fixedly connected to the pad 204 by glue. Finally, the outer side of the pad 204 is fixedly connected to the magnetic block 203 by glue. The two groups of inductors 2 are connected in parallel to increase the output current and power of the inductor 2.

[0036] For further information, see Figure 1 , 4 As shown in , 5, the winding directions of the first winding 207 and the second winding 208 are opposite to each other, forming a mirror structure, the output pieces 209 of the first magnetic column 205 and the second magnetic column 206 are connected to the same inductor output board 201; the input pieces 2010 of the first magnetic column 205 and the second magnetic column 206 are connected to the same inductor input board 202, and the bottom surface of the inductor input board 202 is connected to the positive output board 303 of the transformer 3, which is used to introduce the current generated by the transformer 3 into the inductor 2.

[0037] Specifically, by designing the windings of the two groups of inductors 2 to be opposite, the phases of the two groups of inductors 2 are at the same end, and the output direction of the current is the same, so that the two groups of inductors 2 can output current through the same inductor output board 201 to achieve parallel connection of the two groups of inductors 2. This design method does not need to rely on a connection structure to connect the two groups of inductors 2 in parallel, thereby achieving the reduction of the integrated structure; one end of the two groups of inductors 2 connected in parallel outputs current through the inductor output board 201, and the other end is provided with an inductor input board 202 to input current into the inductor 2, and the bottom surface of the inductor input board 202 is connected to the positive output board 303 of the transformer 3, so that the current generated by the transformer 3 can be input into the inductor 2, which not only plays a filtering role in the circuit to filter out the clutter in the current, making the DC power purer and more stable, but also the design of the inductor input board 202 and the positive output board 303 can achieve the reduction of the integrated structure.

[0038] For further information, see Figure 1 , 3 As shown, the output member 209 is disposed on the top surface of the inductor output plate 201 , a portion of the inductor output plate 201 is laid on the top surface of the glass fiber board 106 , and another portion is located outside the main housing 101 .

[0039] Specifically, the inductor output plate 201 extends to the outside of the main shell 101 to output the pure current generated by the inductor 2; the inductor output plate 201 connects the output component 209 and the glass fiber board 106, so that the heat generated by the inductor 2 is transferred to the glass fiber board 106 through the output component 209, and then passes through the glass fiber board 106, the partition plate 105, the main shell 101, and finally transferred to the bottom plate 102, thereby further improving the heat dissipation effect of the device.

[0040] Preferably, see Figure 3 , 4 As shown, a partition 107 is provided between the first winding 207 and the second winding 208, and a high-temperature tape is sleeved on the partition 107. The side of the partition 107 is fixed on the partition plate 105, and the high-temperature tape may or may not contact the first winding 207 or the second winding 208.

[0041] Specifically, the sides of the first winding 207 and the second winding 208 can be transferred to the partition plate 105 through the partition 107, and the partition 107 and the windings are insulated by high-temperature tape, so that the partition 107 can transfer the heat inside the inductor 2 to the partition plate 105 through the partition 107, thereby increasing the heat dissipation area of ​​the inductor 2, thereby further improving the heat dissipation effect.

[0042] Preferably, the winding integration includes a first primary winding, a second primary winding, a first secondary winding and a second secondary winding, and the bracket 304 is wound with the first primary winding, the first secondary winding, the second secondary winding and the second primary winding in sequence from the inside to the outside, and a negative output plate 301 is respectively provided at one end of the first secondary winding and the second secondary winding.

[0043] Specifically, the bracket 304 is wound with a first primary winding, a first secondary winding, a second secondary winding and a second primary winding in sequence from the inside to the outside. A negative output plate 301 is provided at one end of the first secondary winding and the second secondary winding respectively. The negative output plate 301 is used to output the converted current to power other devices. Through this winding method, the layout of the winding can be optimized, and the leakage inductance and interlayer distributed capacitance of the transformer 3 are effectively reduced, thereby reducing electromagnetic interference and voltage and current stress, and improving the performance and reliability of the switching power supply. In addition, a suitable winding method can be designed according to the specific requirements and output characteristics of the power supply.

[0044] Furthermore, the bracket 304 and the winding integration are both in two groups, the winding directions of the two groups of winding integration are opposite, forming a mirror structure, and the negative output plates 301 of the two groups are located at the same end.

[0045] Furthermore, an alumina ceramic piece is provided around the portion of the negative output plate 301 located at the main housing 101 , and one end of the alumina ceramic piece away from the negative output plate 301 is fixedly connected to the bottom plate 102 .

[0046] Specifically, one end of the alumina ceramic piece is designed in the shape of the negative output plate 301 and is wrapped around the negative output plate 301 to increase the contact area between the alumina ceramic piece and the negative output plate 301 as much as possible, and the other end of the alumina ceramic piece is fixedly connected to the bottom plate 102. The alumina ceramic piece has good thermal conductivity and insulation effect, so the heat generated by the transformer 3 can be further transferred to the bottom plate 102 through the alumina ceramic piece, thereby further improving the heat dissipation effect of the device.

[0047] Specifically, by designing the windings of the two sets of transformers 3 to be opposite, the phases of the two sets of transformers 3 are at the same end, and the output direction of the current is the same, so that the two sets of transformers 3 can output current through the same negative output plate 301 to achieve parallel connection of the two sets of transformers 3. This design method does not need to rely on a connection structure to connect the two sets of transformers 3 in parallel, thereby achieving a reduction in the size of the integrated structure; and the other ends of the two sets of transformers 3 can input current to the inductor 2 through the same positive output plate 303, further reducing the size of the integrated structure.

[0048] Preferably, see Figure 6 , 7As shown, a first epoxy plate 103 and a second epoxy plate 104 are respectively provided at both ends of the main shell 101, wherein a threading hole is provided on the first epoxy plate 103 away from the negative output plate 301, and the input line 302 of the transformer 3 is passed through the threading hole, and a plurality of grooves are provided on the second epoxy plate, which are used for the negative output plate 301 to pass through to the outside of the epoxy plate.

[0049] Specifically, both ends of the opening of the main shell 101 are covered by a first epoxy board 103 and a second epoxy board 104 respectively, so that the shell 1 forms a sealed structure, thereby combining the inductor and the transformer 3 inside a closed space. Because the inductor and the transformer 3 both need to have current input and output components, these components need to be connected to the outside, so a threading hole is set on the first epoxy board 103 and a groove is set on the second epoxy board, so as not to affect the normal use of the current input and output ends.

[0050] Preferably, see Figure 3 As shown, the main shell 101 includes an upper shell 1011 and a lower shell 1012, and a partition plate 105 is arranged between the upper shell 1011 and the lower shell 1012. The upper shell 1011, the lower shell 1012 and the partition plate 105 are fixedly connected by the same set of bolt assemblies 108, and a plurality of bolt holes are opened on the bottom plate 102, which are used to fix the bottom plate 102 to the water cooling plate.

[0051] Specifically, the main shell 101 is divided into an upper shell 1011 and a lower shell 1012, which facilitates the disassembly of the upper shell 1011, the lower shell 1012 and the partition plate 105, thereby facilitating the installation and removal of the inductor 2 and the transformer 3, and also facilitating the maintenance and inspection of the inductor 2 and the transformer 3; it is convenient to install the inductor and transformer combination device on a water-cooled plate to achieve the heat dissipation effect, and will not affect the use of the inductor and transformer combination device.
