Description

Technical Field

[0001] The utility model relates to the technical field of power electronic equipment, in particular to an integrated structure of a water-cooled high-frequency transformer and an inductor. Background Art

[0002] With the mature application of high-power and high-frequency inductors and transformers in solar photovoltaic inverters, charging piles, UPS, and energy storage devices, inductors are used more and more frequently in these products. With the development of technology, the power of inductors has also increased, and the heat generated by inductors and transformers has gradually increased. The heat dissipation of inductors and transformers has always been a difficult problem to solve in this field.

[0003] In the prior art, water-cooled inductors and transformers are a design solution with better heat dissipation. Water-cooled inductors and transformers have the characteristics of heat dissipation blocks, small size, and high power density. However, water-cooled inductors and transformers are prone to leakage and cause short circuit failures. In addition, independent water cooling is expensive and costly. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an integrated structure of a water-cooled high-frequency transformer and an inductor, which can not only solve the heat dissipation problem, but also avoid short-circuit failures caused by leakage and reduce costs.

[0005] The solution of the utility model to solve the technical problem is:

[0006] An integrated structure of a water-cooled high-frequency transformer and an inductor, comprising:

[0007] A water-cooling base, wherein the water-cooling base is hollow to form a cavity, and the cavity is open upward;

[0008] A differential mode inductor, the differential mode inductor is disposed in the cavity and connected to the bottom surface of the cavity;

[0009] A transformer, the transformer being disposed in the cavity and connected to the bottom surface of the cavity;

[0010] A potting filler is filled in the cavity to fix the differential mode inductor and the transformer.

[0011] The utility model has at least the following beneficial effects: the differential mode inductor and the transformer are fixed in the cavity of the water-cooling base by means of a potting filler, and when water cooling is performed, the water flow for cooling flows through the water-cooling base and contacts the outer wall surface and the bottom surface of the water-cooling base, thereby cooling the differential mode inductor and the transformer in the cavity and achieving a good heat dissipation effect; the potting filler has a certain heat conductivity, and can further improve the heat dissipation effect of the water flow on the outer side of the water-cooling base on the differential mode inductor and the transformer; since the potting filler is used to pot the differential mode inductor and the transformer, and the water flow does not directly contact the differential mode inductor and the transformer, the differential mode inductor and the transformer will not be short-circuited, thereby improving the safety of water cooling and improving the service life of the differential mode inductor and the transformer; in addition, the water cooling base has a simple structure and a low cost, and can greatly reduce the production cost of the integrated structure of the water-cooled high-frequency transformer and the inductor.

[0012] As a further improvement of the above technical solution, the water cooling base is provided with a partition, which is connected to the inner wall of the cavity and divides the cavity into multiple chambers, and the differential mode inductor and the transformer are respectively located in one chamber. The provision of the partition can allow a certain distance between the differential mode inductor and the transformer to increase the length of the water flow, which is more conducive to heat dissipation.

[0013] As a further improvement of the above technical solution, each of the chambers is provided with a positioning groove, the positioning groove is located on the bottom surface of the chamber, the groove wall of the positioning groove coincides with the lower end of the differential mode inductor or the lower end of the transformer, and the lower end of the differential mode inductor or the lower end of the transformer is clamped in the positioning groove.

[0014] Since the positioning groove can fix the position of the differential-mode inductor and the transformer, when potting is performed in the chamber, the flow of the potting filler can be avoided to cause the differential-mode inductor and the transformer to move in the chamber, thereby ensuring that the differential-mode inductor and the transformer are in a preset position and the distance between the differential-mode inductor and the transformer is ensured to ensure the heat dissipation effect.

[0015] As a further improvement of the above technical solution, a positioning column is provided on the upper end surface of the partition, the positioning column protrudes upward from the potting filler, and a second positioning hole is provided on the upper end surface of the positioning column, and the second positioning hole extends up and down. Providing the second positioning hole on the partition can enhance the internal strength of the water cooling base, thereby improving the connection strength with equipment such as a charging pile.

[0016] As a further improvement of the above technical solution, the lower surface of the water cooling base is provided with a downwardly protruding block. The water flow for cooling flows through the water cooling base, and the setting of the block can increase the contact area between the water cooling base and the water flow, thereby improving the heat dissipation effect.

[0017] As a further improvement of the above technical solution, the upper end surface of the water-cooling base is provided with a first positioning hole opening upward, and the outer wall surface of the water-cooling base is provided with a third positioning hole. The first positioning hole and the third positioning hole have different orientations, and the water-cooling base can be fixed from different directions, thereby improving the installation strength of the integrated structure of the water-cooled high-frequency transformer and the inductor and the charging pile and other equipment.

[0018] As a further improvement of the above technical solution, the outer wall surface of the water-cooling base is provided with a wire groove, which runs through the upper and lower end surfaces of the water-cooling base and opens away from the cavity. The wire groove is not connected to the cavity, and the wire groove is used to store the wires of the differential mode inductor and the transformer, making the wires more neat and beautiful, and more convenient for connecting the differential mode inductor and the transformer with other electrical components.

[0019] As a further improvement of the above technical solution, the differential mode inductor includes an inductor coil and an inductor core, the inductor core is provided with a middle column, the inductor coil is provided with an inner coil and an outer coil, the inner coil is located in the ring hole of the outer coil, the middle column is passed through the ring hole of the inner coil, and the inner coil and the outer coil are in a continuous winding structure. By adopting the inductor coil formed by the continuous winding structure of the inner coil and the outer coil, the inductor coil of the differential mode inductor can have more turns in a smaller space, thereby increasing the inductance of the differential mode inductor and saving space.

[0020] As a further improvement of the above technical solution, the integrated structure of the water-cooled high-frequency transformer and the inductor further includes a temperature sensor, and the temperature sensor is provided in plurality, and the plurality of temperature sensors are respectively connected to the differential mode inductor and the transformer to detect the temperature of the differential mode inductor and the transformer. The temperature sensor can transmit the temperature information of the differential mode inductor and the transformer to the external temperature monitor, so that the temperature of the differential mode inductor and the transformer can be monitored, so that the differential mode inductor and the transformer can be cooled in time, and the differential mode inductor and the transformer can be better protected.

[0021] As a further improvement of the above technical solution, the water-cooled base is provided with an upstream end and a downstream end, the differential mode inductor is located on one side of the upstream end, and the transformer is located on one side of the downstream end. The water flow used to reduce the temperature of the differential mode inductor and the transformer flows from the upstream end to the downstream end of the water-cooled base, that is, the water flow first passes through the differential mode inductor and then passes through the transformer. Such an arrangement can more effectively take away heat and achieve a good heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0037] Reference Figures 1 to 8 The embodiment of the utility model proposes an integrated structure of a water-cooled high-frequency transformer and an inductor, which includes a differential-mode inductor 200, a transformer 300 and a water-cooled base 100, wherein the water-cooled base 100 is hollow to form a cavity 110, and the cavity 110 is opened upward, and the differential-mode inductor 200 and the transformer 300 are both arranged in the cavity 110, and are respectively connected to the bottom surface of the cavity 110.

[0038] In this embodiment, after the differential mode inductor 200 and the transformer 300 are installed in the cavity 110 , the gap in the cavity 110 is filled with a potting filler 400 , thereby fixing the differential mode inductor 200 and the transformer 300 in the cavity 110 .

[0039] It is understandable that when water cooling is performed, the water used for cooling flows through the water cooling base 100 and contacts the outer wall and bottom surface of the water cooling base 100, thereby cooling the differential mode inductor 200 and the transformer 300 in the cavity 110, achieving a good heat dissipation effect.

[0040] It is understandable that, due to the provision of the water cooling base 100 , the water flow will not directly contact the differential mode inductor 200 and the transformer 300 , and the differential mode inductor 200 and the transformer 300 are not prone to short circuit, thereby improving the safety and service life of the product.

[0041] It is understandable that the potting filler 400 can not only fix the differential mode inductor 200 and the transformer 300, but also play a role in heat conduction. The potting filler 400 can be a silicone potting material, an epoxy resin potting material, etc. In this embodiment, the potting filler 400 is an epoxy resin with a thermal conductivity of 2.0W / (m·K). Compared with silicone potting, epoxy resin has less thermal deformation and generates less stress, which can better protect the differential mode inductor 200 and the transformer 300.

[0042] Reference Figure 8 The transformer 300 in this embodiment is an isolation transformer, using EE-shaped PC96 ferrite as the transformer core 310, and the excitation wire as the winding 320, which is wound in a sandwich structure. It can be understood that the frequency of the transformer 300 is relatively high, and the excitation wire (with multiple strands of twisted wire) is required in high frequency conditions, and the twisted wire is a soft wire, and the transformer 300 is fixed by potting, which has a better fixing effect.

[0043] In this embodiment, if Figure 6 As shown, the differential mode inductor 200 includes an inductor coil 210 and an inductor core 220. The inductor core 220 is provided with a middle column 221. The inductor coil 210 includes an inner coil 211 and an outer coil 212. The inner coil 211 is located in the annular hole of the outer coil 212, and the middle column 221 is penetrated through the annular hole of the inner coil 211.

[0044] It is worth noting that Figure 7 As shown, the differential mode inductor 200 in this embodiment adopts a structure in which the inner coil 211 and the outer coil 212 are wound together, and the outer coil 212 and the inner coil 211 are wound by a flat wire. It can be understood that by adopting the structure in which the inner coil 211 and the outer coil 212 are wound together, the number of turns of the inductor coil 210 of the differential mode inductor 200 can be increased in a smaller space, thereby increasing the inductance of the differential mode inductor 200, reducing the volume, and saving space.

[0045] In this embodiment, the flat wire is a 3 mm×8 mm flat enameled copper wire. By adopting a structure in which the inner coil 211 and the outer coil 212 are wound together, it is beneficial to control the height of the product coil and reduce the space size.

[0046] In this embodiment, the differential mode inductor 200 is provided with two groups of inductor coils 210, the middle column 221 of the inductor core 220 is passed through the ring hole of the inner coil 211 of the two groups of inductor coils 210, the two groups of inductor coils 210 are arranged in the front-to-back direction, and the inner coil 211 and the outer coil 212 of the two groups of inductor coils 210 are both wound along the front-to-back direction.

[0047] It is understandable that, considering the comprehensive cost and performance, the inductor core 220 can use a magnetic powder core to control the loss of the product. For circuits with a frequency of 10KHZ to 100KHZ, iron silicon nickel, iron silicon aluminum and aerosolized powder cores are used as the inductor core 220. In this embodiment, the inductor core 220 is formed by splicing three EE-shaped powder cores, and the differential mode inductor 200 produced has high efficiency and low loss.

[0048] In this embodiment, the differential mode inductor 200 and the transformer 300 disposed in the cavity 110 are both half-potted by the potting filler 400, and the potting filler 400 is filled to half the height of the transformer 300. Of course, the height filled by the potting filler 400 can also be higher or lower than half the height of the transformer 300, as long as the transformer 300 and the differential mode inductor 200 can be well fixed.

[0049] In the present embodiment, the differential mode inductor 200 and the transformer 300 disposed in the cavity 110 are both placed laterally, that is, the long side of the inductor coil 210 of the differential mode inductor 200 extends in the horizontal direction, and the long side of the winding 320 of the transformer 300 is arranged in the horizontal direction. It can be understood that such placement can make the contact area between the inductor coil 210 and the water-cooled base 100 and the contact area between the transformer 300 and the water-cooled base 100 larger, and the center of gravity of the inductor coil 210 and the transformer 300 can be lowered, so that the center of gravity of the inductor coil 210 and the transformer 300 is closer to the water-cooled base 100, thereby improving the heat dissipation effect.

[0050] In addition, since the differential mode inductor 200 is arranged laterally, the two groups of inductor coils 210 of the differential mode inductor 200 and the three EE-shaped powder cores making up the inductor core 220 can be potted with the potting filler 400, thereby improving the fixing effect of the differential mode inductor 200.

[0051] In this embodiment, the integrated structure of the water-cooled high-frequency transformer and the inductor further includes a temperature sensor 500, which can be connected to an external temperature monitor. A plurality of temperature sensors 500 are provided, and the plurality of temperature sensors 500 are respectively connected to the differential mode inductor 200 and the transformer 300, so as to monitor the temperature of the inductor coil 210 of the differential mode inductor 200 and the winding 320 of the transformer 300, so as to timely detect the overheating of the differential mode inductor 200 and the transformer 300, so as to timely perform the temperature reduction treatment.

[0052] It is understandable that the temperature sensor 500 may be a thermistor, a thermocouple, etc. In this embodiment, the temperature sensor 500 is a negative temperature coefficient thermistor (Negative Temperature Coefficient, NTC).

[0053] In this embodiment, one differential mode inductor 200 and three transformers 300 are provided. It is understandable that the number of the differential mode inductor 200 and the transformer 300 can be selected according to actual needs.

[0054] Among them, the number of transformers 300 can be selected according to the size and requirements of the transformer 300. Generally, the larger the volume of the transformer 300, the larger its capacity. Under the condition of equal capacity requirements, selecting multiple transformers 300 can avoid heat concentration caused by the large volume of the transformer 300, and can effectively take away the heat, thereby achieving an ideal temperature rise effect.

[0055] It is understandable that, since the differential mode inductor 200 in this embodiment adopts a structure in which the outer coil 212 and the inner coil 211 are continuously wound, the required performance can be met by using one differential mode inductor 200 .

[0056] In this embodiment, three transformers 300 are arranged in sequence along the front-to-back direction, and the differential mode inductor 200 is arranged at the front end or rear end of the three transformers 300. Specifically, the front end and the rear end of the water cooling base 100 are the upstream end and the downstream end of the water flow, respectively, and the differential mode inductor 200 is arranged at the upstream end of the water cooling base 100. When in use, the water flow flows from the upstream end of the water cooling base 100 to the downstream end of the water cooling base 100, that is, the water flow flows from one end of the differential mode inductor 200 to the end of the transformer 300 farthest from the differential mode inductor 200.

[0057] It is understandable that such a configuration is because the current passing through the differential mode inductor 200 is larger, while the current passing through the transformer 300 is smaller. Placing the differential mode inductor 200 at the upstream end of the water flow and placing the transformer 300 at the downstream end of the water flow can more effectively remove heat.

[0058] In some embodiments, the water-cooled base 100 is provided with a partition 120, the partition 120 is connected to the inner wall surface of the cavity 110, and the partition 120 divides the cavity 110 into multiple chambers, and the differential mode inductor 200 and the transformer 300 are respectively located in different chambers. In this embodiment, three partitions 120 are provided, and the three partitions 120 divide the cavity 110 into four chambers, and one differential mode inductor 200 and three transformers 300 are respectively located in the four chambers.

[0059] It can be understood that placing the differential-mode inductor 200 and the transformer 300 in four chambers respectively, with a certain distance between the differential-mode inductor 200 and the three transformers 300, is conducive to the use of potting filler 400 for glue fixation, and a certain distance is set between the differential-mode inductor 200 and the three transformers 300 to increase the length of the water flow, which is conducive to heat dissipation.

[0060] In this embodiment, positioning grooves 130 are respectively provided in the four chambers. The positioning grooves 130 are provided on the bottom surface of the chamber and open upward. The groove wall of the positioning groove 130 is consistent with the lower end of the differential mode inductor 200 or the lower end of the transformer 300. The lower end of the differential mode inductor 200 or the lower end of the transformer 300 can be snapped into the positioning groove 130. The groove wall of the positioning groove 130 can fix the position of the differential mode inductor 200 or the transformer 300.

[0061] It is understandable that after the differential-mode inductor 200 and the transformer 300 are placed into the cavity 110 and then potted, the flow of the potting filler 400 may cause the differential-mode inductor 200 and the transformer 300 located in the cavity to shift, and the distance between two adjacent transformers 300 or between the differential-mode inductor 200 and the transformer may be less than the preset distance, thereby failing to achieve the preset heat dissipation effect.

[0062] In this embodiment, since the positioning groove 130 can fix the positions of the differential-mode inductor 200 and the transformer 300, when potting is performed in the chamber, the flow of the potting filler 400 can be avoided to drive the differential-mode inductor 200 and the transformer 300 to move in the chamber, thereby ensuring that the differential-mode inductor 200 and the transformer 300 are in a preset position, ensuring the distance between adjacent transformers 300 and the distance between the differential-mode inductor 200 and the transformer 300, and further ensuring smooth heat dissipation.

[0063] In this embodiment, first positioning holes 160 are respectively provided at the four corners of the upper end surface of the water-cooled base 100. The first positioning holes 160 are open upward and are used to fix the integrated structure of the water-cooled high-frequency transformer and the inductor from above using screws and other connecting parts, which is conducive to installing the integrated structure of the water-cooled high-frequency transformer and the inductor on equipment such as charging piles for use.

[0064] It is understandable that the first positioning holes 160 are disposed at the four corners of the water cooling base 100 , so that the hole distance of the first positioning holes 160 can be maximized, thereby maximizing the axis distance of the screws used to fix the water cooling base 100 and improving the stability of the fixation.

[0065] In this embodiment, a positioning column 140 is provided on the upper end surface of the partition 120. The positioning column 140 extends in the up-down direction and extends upward from the potting filler 400. A second positioning hole 141 is provided on the upper end surface of the positioning column 140. The second positioning hole 141 extends in the up-down direction.

[0066] It is understandable that the second positioning hole 141 is provided on the partition 120 to enhance the internal strength of the water-cooled base 100 and further strengthen the stability of the integrated structure installation of the water-cooled high-frequency transformer and the inductor.

[0067] In this embodiment, the outer wall surface of the water-cooling base 100 is provided with a third positioning hole 170, which is extended in the horizontal direction and can be provided on the left and right sides of the water-cooling base 100, or on the front and rear sides of the water-cooling base 100. It can be understood that the provision of the third positioning hole 170 can strengthen the fixation from the side of the water-cooling base 100, and can further strengthen the stability of the integrated structure installation of the water-cooled high-frequency transformer and the inductor.

[0068] It is understandable that in other embodiments, in order to improve the fixing strength of the water cooling base 100, or to meet the fixing strength requirements, the hole position of the first positioning hole 160 is extended outward for a distance. Although such a setting can increase the hole distance between each first positioning hole 160 and improve the fixing stability, it undoubtedly increases the occupied volume of the water cooling base 100. In this embodiment, the second positioning hole 141 and the third positioning hole 170 are provided, which can improve the fixing strength of the water cooling base 100 and the charging pile and other equipment without extending the hole position of the first positioning hole 160 outward, thereby avoiding the increase in the volume of the water cooling base 100.

[0069] In this embodiment, a protrusion 150 is provided on the lower surface of the water cooling base 100, and the protrusion 150 is provided to protrude downward. It can be understood that the provision of the protrusion 150 can increase the contact area between the water cooling base 100 and the water flow, thereby improving the heat dissipation effect.

[0070] It can be understood that the number of the protrusions 150 is not specifically limited herein. In the present embodiment, four protrusions 150 are arranged under each chamber, and the protrusions 150 are symmetrically arranged on the left and right sides of the lower surface of the water-cooling base 100. Each protrusion 150 is extended in the left and right directions, and a water flow gap is provided between the left and right protrusions 150 located on the same straight line.

[0071] In this embodiment, a wire groove 180 is provided on the outer wall of the water-cooling base 100. The wire groove 180 runs through the upper and lower end surfaces of the water-cooling base 100, and the wire groove 180 is opened away from the cavity 110. It can be understood that the wire groove 180 is not connected to the cavity 110, and the wire groove 180 is used to receive the wires of the differential mode inductor 200 and the transformer 300, including the wires of the temperature sensor 500, so that the wires are more neat and beautiful.

[0072] The water-cooling base 100 in this embodiment is made of high thermal conductivity aluminum with a thermal conductivity of 150W / (m·K), which has good thermal conductivity and is more conducive to the heat dissipation of the differential mode inductor 200 and the transformer 300. It can be understood that the water-cooling base 100 has a simple structure and low cost, which can greatly reduce the production cost of the integrated structure of the water-cooled high-frequency transformer and the inductor.

[0073] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
