Description
[Technical Field]
[0001] This invention relates to a device having an inductor and a high thermal conductivity frame and a method for manufacturing the same, particularly a device having an inductor and a high thermal conductivity frame and a method for manufacturing the same, which enhances thermal conductivity by embedding the frame in a magnetic powder material to contact electronic components. [Previous Technology]
[0002] As shown in Figure 1, US Patent 11770916 discloses an inductor structure 1, in which a metal strip 3 made of a high thermal conductivity material is wrapped around the outer portion of the inductor. This metal strip 3 is designed to enhance thermal conductivity between the inductor and the integrated circuit chip, thereby improving heat dissipation efficiency. The metal strip 3 can be made of high thermal conductivity materials such as copper, silver, or aluminum, and its width can be adjusted as needed to ensure effective thermal connection with the underlying integrated circuit chip.
[0003] However, this prior art has some obvious drawbacks. First, the metal strip 3 is installed by wrapping after the inductor is manufactured. Since the metal strip 3 needs to be precisely bent to fit the shape of the inductor, it is difficult to ensure a perfect fit between the metal strip 3 and the inductor surface during manufacturing. Especially at the bends, it is difficult to achieve a precise 90-degree bend, which leads to uneven or excessive gaps between the metal strip 3 and the inductor, thus affecting the heat conduction efficiency.
[0004] Secondly, a thermal interface material (TIM) is needed to connect the metal strip 3 to the inductor. Since the thermal conductivity of TIM is relatively low (typically 1 to 2 W / mK), and there is a gap between the start and end points of the metal strip 3, this further increases the thermal resistance and weakens the overall heat transfer efficiency. Furthermore, because the metal strip 3 mainly wraps around the side of the inductor, heat needs to be transferred along a longer path. This lengthens the heat transfer path from the integrated circuit chip to the heat sink, increasing the thermal resistance and thus affecting the heat dissipation effect.
[0005] Finally, heat in the middle part of the inductor is difficult to transfer to the metal strip 3 in a timely and effective manner, mainly relying on vertical heat conduction. However, the presence of multiple layers of materials and interfaces in the vertical direction, such as TIM and magnetic powder materials, increases thermal resistance and limits the overall heat dissipation performance. These drawbacks limit the performance of this prior art in terms of efficient heat dissipation and urgently require improvement.
[0006] In view of the shortcomings of the prior art, the present invention provides a design of a device with an inductor and a high heat transfer frame, which can greatly improve the heat dissipation effect through a simple manufacturing process. [Summary of the Invention]

[0022] In one embodiment, the vertical frame is located in the middle portion of the inductor, in contact with the top plate and the bottom plate, providing a heat conduction path to transfer heat from the middle portion of the inductor to the top plate and the bottom plate.
[0023] In one embodiment, the frame is directly embedded in the first magnetic powder material during the manufacturing process of the inductor, instead of using a metal sheet to cover it after the inductor is made, so as to avoid uneven or excessive gaps caused by the metal sheet covering process, thereby improving heat dissipation performance.
[0024] In one embodiment, the inductor and high thermal conductivity frame device further includes: a second magnetic powder material that covers the exterior of a structure consisting of the first magnetic powder material, the internal conductor and the frame.
[0025] In one embodiment, the first magnetic powder material and the second magnetic powder material are two different magnetic powders. The first magnetic powder material is used to determine the inductance value of the inductor, and the second magnetic powder material is used for outer layer protection and heat dissipation.
[0026] In another viewpoint, the present invention provides a method for manufacturing an apparatus having an inductor and a high thermal conductivity frame. The apparatus includes an inductor having at least two internal conductors and a frame made of a high thermal conductivity material. The frame includes a top plate above the at least two internal conductors, a bottom plate below the at least two internal conductors, and at least one vertical frame between the top plate and the bottom plate. The frame is embedded in and in direct contact with a magnetic powder material. The method for manufacturing the apparatus includes: (a) providing the at least two internal conductors and the frame; (b) placing the at least two internal conductors and the frame in a first mold, positioning the at least two internal conductors and the top plate, bottom plate, and vertical frame of the frame at predetermined positions; (c) adding a first magnetic powder material to the first mold, filling the space between the frame and the internal conductors with the first magnetic powder material; (d) ... The first mold is subjected to high temperature and high pressure treatment to integrally form the first magnetic powder material, the internal conductor and the frame, forming a structure of an inductor and a frame embedded in the first magnetic powder material; and (e) the formed structure is removed from the first mold to produce the device having an inductor and a high heat transfer frame.
[0027] In one embodiment, in step (a), the internal conductor has a clip-on structure to reduce DC resistance.
[0028] In one embodiment, the manufacturing method of the aforementioned device having an inductor and a high heat transfer frame further includes: (f) placing the structure in a second mold to position the structure at a predetermined position; (g) adding a second magnetic powder material to the second mold to fill the outside of the structure; and (h) subjecting the second mold to high temperature and high pressure treatment to integrally form the second magnetic powder material and the structure to produce the device having an inductor and a high heat transfer frame.
[0029] In one embodiment, in step (d), the frame is directly bonded to the first magnetic powder material without using a thermal interface material.
[0030] In one embodiment, after step (e), the top surface of the inductor can be connected to a high thermal conductivity object via a thermal interface material.
[0031] In another viewpoint, the present invention provides a method for manufacturing an apparatus having an inductor and a high thermal conductivity frame. The apparatus having an inductor and a high thermal conductivity frame includes an inductor having at least two internal conductors and a frame made of a high thermal conductivity material. The frame includes a top plate located above the at least two internal conductors, a bottom plate located below the at least two internal conductors, and at least one vertical frame between the top plate and the bottom plate. The frame is embedded in and in direct contact with the magnetic powder material. The method for manufacturing the apparatus having an inductor and a high thermal conductivity frame includes: (a) manufacturing at least two separate sub-inductors, each sub-inductor having at least one internal conductor and embedded in a first magnetic powder material; (b) providing the frame; and (c) assembling the at least two sub-inductors into the frame such that the top plate and the bottom plate are located on the upper and lower sides of the at least two sub-inductors, respectively, forming a structure to produce the apparatus having an inductor and a high thermal conductivity frame.
[0032] In one embodiment, the manufacturing method of the aforementioned device having an inductor and a high heat transfer frame further includes: (d) placing the structure in a mold to position the structure at a predetermined position; (e) adding a second magnetic powder material to the mold and filling the outside of the structure with the second magnetic powder material; and (f) subjecting the mold to high temperature and high pressure treatment to integrally form the second magnetic powder material and the structure to produce the device having an inductor and a high heat transfer frame.
[0033] In one embodiment, in step (c), the frame is connected to at least two sub-inductors by an adhesive or thermal interface material.
[0034] Compared with the prior art, the present invention has significant advantages. First, during the manufacturing process, the present invention directly embeds a frame made of a high thermal conductivity material into the magnetic powder material of the inductor, forming a tightly bonded structure. This method avoids the manufacturing difficulties caused by wrapping the metal strip after the inductor is manufactured in the prior art, especially the problem of accurately controlling the bend angle and gap during the bending process of the metal strip. Through the direct embedding design, the uneven or excessive gap that may exist between the metal and the inductor is eliminated, thereby greatly improving the thermal conductivity efficiency.
[0035] Secondly, the frame structure of the present invention includes a top plate located above the internal conductor of the inductor and a bottom plate located below, connected by at least one vertical frame located in the middle section. This design provides a direct heat conduction path, enabling efficient transfer of heat generated between the inductor and the electronic components to the top and bottom plates, and then dissipation to the external environment. Compared to the prior art where heat needs to be transferred to the heat sink along a long and tortuous path via the side metal strip, the present invention significantly shortens the heat conduction path, reduces thermal resistance, and improves heat dissipation performance.
[0036] Furthermore, because the frame is directly bonded to the magnetic powder material during manufacturing, there is no need to use a thermal interface material (TIM) to connect the metal and the inductor. This not only simplifies the manufacturing process but also avoids the problem of increased thermal resistance caused by the low thermal conductivity of TIM (typically 1 to 2 W / mK). In the prior art, the heat conduction efficiency was limited because a TIM was required to connect the metal strip and the inductor, and gaps were unavoidable during manufacturing. This invention achieves more efficient heat conduction by directly bonding the frame and the magnetic powder material under high temperature and pressure through a one-time molding process.
[0037] In summary, the present invention overcomes the shortcomings of prior art in terms of manufacturing difficulty, heat conduction path, thermal resistance, and heat dissipation efficiency. Through innovative structural design and manufacturing methods, the present invention provides a more effective heat dissipation solution, particularly suitable for high power density and high heat electronic components, thereby improving the reliability and performance of the device.
[0038] The following detailed description of specific embodiments will make it easier to understand the purpose, technical content, features and effects achieved by the present invention.
Implementation Method
[0064] The drawings in this invention are all schematic and are mainly intended to show the interrelationship between the components of the electronic components. The shapes and sizes are not drawn to scale.
[0065] Figures 2A, 2B, and 2C respectively show cross-sectional schematic diagrams of an embodiment of a device having an inductor and a high thermal conductivity frame according to the present invention. As shown in Figure 2A, the device 10 having an inductor and a high thermal conductivity frame includes an inductor 11 and a frame 12 made of a high thermal conductivity material. The inductor 11 includes at least two internal conductors 101 and a first magnetic powder material 102, the internal conductors 101 being embedded in the first magnetic powder material 102. The frame 12 includes a top plate 103, a bottom plate 104, and at least one vertical frame 105. The top plate 103 is located above the internal conductors 101, the bottom plate 104 is located below the internal conductors 101, and the vertical frame 105 is located between the top plate 103 and the bottom plate 104. The frame 12 is directly embedded in the first magnetic powder material 102.
[0066] Furthermore, the device 10 is positioned above the electronic component 20 and contacts the electronic component 20 via the bottom plate 104 of the frame 12. This effectively conducts the heat generated by the electronic component 20 through the frame 12 to the top plate 103 and the bottom plate 104, further improving heat dissipation performance. In this embodiment, the vertical frame 105 of the frame 12 is located in the middle portion of the inductor 11. This structure provides an effective heat conduction path, transferring heat from the middle portion between the electronic component 20 and the inductor 11 to the top plate 103 and the bottom plate 104 of the frame 12. This design significantly improves heat exchange efficiency and contributes to the overall heat dissipation effect of the device.
[0067] In one embodiment, the top plate 103 and the bottom plate 104 in this frame 12 may optionally have the same or different lengths or widths to optimize heat dissipation.
[0068] In one embodiment, the internal conductor 101 within the frame 12 uses a clip-on structure design, which further reduces the DC resistance of the inductor compared to a coil inductor and improves the efficiency of the inductor in high-current applications, as illustrated in subsequent embodiments.
[0069] In one embodiment, the device 10 can be manufactured through a one-time molding process. The top plate 103, bottom plate 104 and vertical frame 105 of the frame 12 are directly bonded to the first magnetic powder material 102 under high temperature and high pressure, without using a thermal interface material for bonding, thereby eliminating the thermal resistance problem that may occur in the process and achieving the optimal heat dissipation effect.
[0070] It should be noted that thermal interface material (TIM) is a common material in electronic devices, primarily used to fill the gaps between heat-generating components and heat sinks. Because the contact surfaces between heat-generating components (such as integrated circuits, power semiconductor devices, etc.) and heat sinks are usually not perfectly flat, air gaps are created between these irregular surfaces, leading to reduced heat conduction efficiency. Thermal interface materials are used to fill these gaps, reduce thermal resistance, and allow heat to be transferred more effectively from the heat-generating components to the heat dissipation device, such as heat sinks or radiators. There are various types of thermal interface materials, including common ones such as thermally conductive adhesives, thermally conductive pads, thermally conductive tapes, thermally conductive gels, thermally conductive phase change materials, and metal-based thermal interface materials. The thermal conductivity of thermal interface materials is approximately 1 to 2 W / m·K.
[0071] It should be noted that high thermal conductivity materials refer to materials with high thermal conductivity, which can effectively and rapidly transfer heat from one area to another, thereby aiding in thermal management and heat dissipation. Thermal conductivity is usually measured as the amount of heat that can be transferred per unit temperature difference per unit time, and the unit is watts per meter (W / m·K). In the engineering field, the thermal conductivity of high thermal conductivity materials is usually defined as at least greater than 10 W / m·K. In many electronic devices or power module applications, high thermal conductivity materials can also refer to materials with a thermal conductivity greater than 100 W / m·K to meet heat dissipation requirements. Common high thermal conductivity materials include: metallic materials, such as aluminum (~240 W / m·K), copper (~400 W / m·K), silver (~430 W / m·K), etc.; non-metallic materials, such as aluminum nitride (AlN), silicon carbide (SiC), and graphite, which also have high thermal conductivity and good electrical insulation properties, making them very suitable for some applications requiring electrical insulation; composite materials: due to the limitations of single materials, high thermal conductivity fillers (such as boron nitride or carbon nanotubes) are sometimes added to polymer or ceramic matrices to form composite materials with enhanced thermal conductivity properties.
[0072] In this embodiment, the top plate 103 and the bottom plate 104 are connected by a vertical frame 105. In one embodiment, the vertical frame 105 is connected between the top plate 103 and the bottom plate 104, and the vertical frame 105, the top plate 103 and the bottom plate 104 are integrally formed.
[0073] In one embodiment, the frame 12 may be in direct contact with the first magnetic powder material 102, for example, without the need to use a thermal interface material.
[0074] In one embodiment, the top plate 103 and the bottom plate 104 are parallel to each other.
[0075] In one embodiment, the high thermal conductivity material is a formable metal, including steel, copper, silver, gold, aluminum, tungsten, zinc or stainless steel.
[0076] In one embodiment, the high thermal conductivity material is a non-metallic material, including aluminum nitride, silicon carbide or graphite.
[0077] In one embodiment, as shown in FIG2A, the frame 12 and the first magnetic powder material 102 of the inductor 11 are coplanar. That is, the top surface 103a of the top plate 103 and the surface 1021 of the first magnetic powder material 102 are aligned on the same vertical height plane, and the bottom surface 104a of the bottom plate 104 and the surface 1022 of the first magnetic powder material 102 are aligned on the same vertical height plane.
[0078] In one embodiment, as shown in FIG2B, the frame 12 does not extend beyond the surface 1021 or 1022 of the first magnetic powder material 102. That is, the top surface 103a of the top plate 103 does not extend beyond the surface 1021 of the first magnetic powder material 102 in vertical height, and the bottom surface 104a of the bottom plate 104 does not extend beyond the surface 1022 of the first magnetic powder material 102 in vertical height.
[0079] In one embodiment, as shown in FIG2C, the frame 12 extends beyond the surfaces 1021 and 1022 of the first magnetic powder material 102 of the inductor 11. That is, the top surface 103a of the top plate 103 extends beyond the surface 1021 of the first magnetic powder material 102 in vertical height, and the bottom surface 104a of the bottom plate 104 extends beyond the surface 1022 of the first magnetic powder material 102 in vertical height.
[0080] In one embodiment, electronic component 20 includes an integrated circuit chip, an inductor, a capacitor, or a resistor.
[0081] In one embodiment, the frame 12 may be connected to the top plate 103 and the bottom plate 104 by a plurality of vertical frames 105 to improve structural strength.
[0082] In one embodiment, the frame 12 is directly embedded in the first magnetic powder material 102 during the manufacturing process of the inductor 11, instead of using a metal sheet to cover it after the inductor 11 is made, so as to avoid the heat dissipation performance being reduced due to uneven or excessive gaps between the metal sheet and the first magnetic powder material 102 (especially at the turning point of the metal sheet) generated during the metal sheet covering process.
[0083] Figure 3 shows a three-dimensional schematic diagram of the internal conductor 101 and the frame 12 in Figure 2, further demonstrating the three-dimensional structure of the device 10 with an inductor and a high heat transfer frame.
[0084] In this embodiment, the device 10 with an inductor and a high thermal conductivity frame includes an inductor 11 and a frame 12. An internal conductor 101 is embedded in a first magnetic powder material 102 (the first magnetic powder material 102 is not shown; please refer to FIG. 2). A frame is disposed around the first magnetic powder material 102, which is composed of a top plate 103, a bottom plate 104, and at least one vertical frame 105. FIG. 3 clearly shows that the internal conductor 101 uses a clip-on structure design, with the top plate 103 located above the internal conductor 101, the bottom plate 104 located below the internal conductor 101, and the vertical frame 105 located between the top plate 103 and the bottom plate 104, forming a stable support structure.
[0085] In this embodiment, the top plate 103 is a flat structure used to contact other heat dissipation components (such as heat sinks) to conduct the heat generated by the electronic components 20 and the inductor 11 to the external environment. The vertical frame 105 directly penetrates and is fixed between the top plate 103 and the bottom plate 104. The vertical frame is located in the middle part of the inductor, providing a path for heat conduction, effectively transferring heat from the inside of the inductor 11 to the top plate 103 and the bottom plate 104, further improving heat dissipation performance.
[0086] Figure 4 shows a device 30 with an inductor and a high thermal conductivity frame according to one embodiment of the present invention. In this embodiment, the frame 12 includes a top plate 103, a bottom plate 104, and a vertical frame 105 located between the top plate and the bottom plate. The frame 12 is in direct contact with or connected to a first magnetic powder material 102 via a thermal interface material, and covers the upper and lower surfaces of the internal conductor 101 to provide structural support and a heat conduction path.
[0087] As shown in Figure 4, the surface of the top plate 103 is connected to a high thermal conductivity object 106, for example, through a layer of thermal interface material 41. The high thermal conductivity object 106 is, for example, but not limited to, a heat sink. The thermal interface material 41 fills the space between the top plate 103 and the high thermal conductivity object 106 to reduce the contact thermal resistance between them and more effectively conduct the heat generated during the operation of the electronic components 20 and the inductor 11 to the high thermal conductivity object 106. Through this structural design, the high thermal conductivity object 106 can help quickly dissipate the heat generated by the inductor 11 and the electronic components 20, further improving the heat dissipation efficiency of the entire device.
[0088] The high thermal conductivity object 106 is made of a high thermal conductivity material. A high thermal conductivity object refers to a material or structure with high thermal conductivity, capable of rapidly and effectively transferring heat from a heat source to other parts or a heat dissipation system. Such objects are crucial in thermal management applications, especially in electronic devices or high-power components requiring rapid heat dissipation. High thermal conductivity materials typically refer to metallic materials, ceramic materials, or graphite and thermally conductive composite materials. Metals generally have good thermal conductivity, such as copper, aluminum, silver, and gold. Certain ceramic materials, such as aluminum nitride (AlN) and silicon carbide (SiC), also have high thermal conductivity and electrical insulation properties, thus they are often used in packaging materials for electronic components or heat dissipation substrates. Graphite is a material with a unique structure and high thermal conductivity, suitable for use in ultra-thin heat sinks. Some composite materials are made by mixing metals with ceramics or carbon materials, possessing both thermal conductivity and structural strength, achieving optimal results in specific applications. The high thermal conductivity object 106 is, for example, but not limited to, a heat sink or heat fin. Heat sinks are used to handle the heat from electronic components such as processors and power modules, and dissipate heat through convection or radiation. Heat sinks are usually made of metals with high thermal conductivity, which increases the surface area so that heat can be transferred from the components to the environment more quickly.
[0089] FIG5 shows one embodiment of the present invention. As shown in FIG5, in the device 50 having an inductor and a high thermal conductivity frame, the top plate 103 and the bottom plate 104 have different lengths. This embodiment is intended to illustrate that the dimensions of the top plate 103 and the bottom plate 104 can be different, specifically that the length and width can be different, and the length-to-width ratio of each can also be different.
[0090] FIG6 shows an embodiment of the present invention. As shown in FIG6, in the device 70 having an inductor and a high thermal transfer frame, except that the top plate 103 and the bottom plate 104 have different lengths, the vertical frame includes a connecting rod 107, and the connecting rod 107 is connected between the top plate 103 and the bottom plate 104, and the position of the connecting rod 107 can be provided on the side of the inductor 11, rather than necessarily in the middle part of the inductor 11.
[0091] Figures 7, 8, 9 and 10 show several embodiments of the present invention. As shown in Figures 7, 8, 9 and 10, in devices 90, 110, 130 and 150 having an inductor and a high thermal conductivity frame, a connecting rod 107 is connected between a top plate 103 and a bottom plate 104, and in these embodiments, the number of connecting rods 107 may be different, and the positions of the connecting rods 107 may be arranged in different ways.
[0092] FIG11 shows an embodiment of the present invention. As shown in FIG11, in the device 170 having an inductor and a high thermal transfer frame, the lengths of the top plate 103 and the bottom plate 104 may optionally not exceed the vertical frame, the vertical frame including a connecting rod 107, and the connecting rod 107 connecting between the top plate 103 and the bottom plate 104, and the position of the connecting rod 107 may be set in the middle part of the inductor 11.
[0093] Figure 12 shows a device 190 with an inductor and a high thermal conductivity frame according to one embodiment of the present invention. In this embodiment, the frame 12 includes a top plate 103, a bottom plate 104, and a vertical frame 105 connecting the top plate 103 and the bottom plate 104. The frame 12 may be in direct contact with or connected to a first magnetic powder material 102 via a thermal interface material, and covers the upper and lower surfaces of the internal conductor 101 to provide structural support and a heat conduction path. The top plate 103, the bottom plate 104, and the vertical frame 105 are, for example, integrally formed.
[0094] As shown in Figure 12, a high thermal conductivity object 106 can be connected to the side of the frame 12 for heat dissipation. In this embodiment, a high thermal conductivity object 106 is connected to the side of the top plate 103 of the frame 12 and the side of the bottom plate 104 of the frame 12, thereby more effectively conducting the heat generated by the electronic components 20 and the inductor 11 during operation to the high thermal conductivity object 106. Furthermore, the side of the top plate 103 and the side of the bottom plate 104 are connected to the heat sink 106, for example, through a layer of thermal interface material (thermal interface material 41 as shown in Figure 47). Through this structural design, the high thermal conductivity object 106 can help quickly dissipate the heat generated by the inductor 11 and the electronic components 20, further improving the heat dissipation efficiency of the entire device.
