The electric core column is arranged in a glue filling cavity in a direction perpendicular to a mounting surface, and the coil is arranged on the electric core column along a center line. Since the center line is perpendicular to the mounting surface, a plurality of coil leads of the coil can be arranged in a direction perpendicular to the mounting surface, so that a part of the plurality of coil leads is arranged close to the mounting surface. The heat-conducting glue is filled in a gap between the mounting surface and the coil, so that the coil is wrapped by the heat-conducting glue. After the electric reactance is attached to the surface of an external heat dissipation structure, the heat dissipation is realized.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Heating, ventilation, and air conditioning (HVAC) systems are used to regulate indoor environments, including functions such as heating, ventilation, and air conditioning. Taking air conditioning systems as an example, an air conditioning system can be a multi-split system used in buildings, where one or more outdoor units are connected in parallel to multiple indoor units, forming a refrigerant loop to allow refrigerant to circulate. Figure 1The outdoor unit 300 of the air conditioning system is shown, which has a housing 301, an electronic control device 200 and a fan 302 disposed inside the housing 301.

[0029] The housing 301 is the external structure of the HVAC equipment, protecting internal components, providing a mounting base, and optimizing airflow. The electrical control unit 200 is the core control component of the HVAC equipment. Installed inside the housing 301, the electrical control unit 200 facilitates maintenance and replacement, and also streamlines the installation and layout of the overall HVAC structure. The electrical control unit 200 is responsible for precisely controlling the operation of the HVAC equipment. It contains various control circuits that use electronic components and wiring to control the HVAC equipment's start-up, stop, temperature adjustment, and mode switching.

[0030] The electronic control device 200 and the air blower 302 are housed inside the casing 301, which forms an air duct. The air blower 302 is located at the top of the casing 301, that is, at the top of the air duct, and blows air upwards. The electronic control device 200 is located inside the air duct, so the airflow within the air duct can carry away the heat generated by the electronic control device 200, ensuring the heat dissipation effect of the electronic control device 200.

[0031] The housing 301 is provided with an inspection port 300a, such as Figure 1 The figure shown is a three-dimensional structural diagram of an electronic control device 200 provided at the access port 300a of the outdoor unit 300 according to an embodiment of this application. The electronic control device 200 is located at the access port 300a, and maintenance personnel can quickly access the electronic control device 200 without having to enter the casing 301 to operate the electronic control device 200, thereby greatly improving the efficiency of maintenance and repair.

[0032] Please see Figure 2 and Figure 3 The electronic control device 200 of this application embodiment includes a heat dissipation structure, a cover 203, and multiple power components. The heat dissipation structure includes a cold plate body 201, a heat dissipation channel inside the cold plate body 201, and a heat exchange medium flowing through the heat dissipation channel. The cold plate body 201 has a first heat dissipation surface 202. The cover 203 is connected to the cold plate body 201, and the cover 203 and the first heat dissipation surface 202 together form a heat dissipation cavity. When multiple power components are disposed in the heat dissipation cavity, the cold plate body 201 can directly receive the heat generated by the power components, or the cold plate body 201 can cool the gas in the heat dissipation cavity, thereby dissipating heat from the power components.

[0033] like Figure 3As shown, multiple power components include a reactor 100. The reactor 100 is used to suppress high-order harmonics in the circuit and protect electronic devices from damage. The reactor 100 generates a large amount of heat during operation. In addition to heat dissipation through the cold plate body 201, the structure of the reactor 100 in this embodiment is improved to enhance its heat dissipation efficiency. Specifically, the reactor 100 is disposed on the first heat dissipation surface 202 and mounted on the cold plate body 201, allowing the cold plate body 201 to directly dissipate heat from the reactor 100.

[0034] Please see Figure 4 and Figure 5 This application provides an embodiment of a reactor 100, which includes a base plate 1, a housing 2, a battery core 3, a coil 4, thermally conductive adhesive, and a connector 5. The base plate 1 has a mounting surface 11, the housing 2 is connected to the mounting surface 11, and the housing 2 and the mounting surface 11 together form a potting cavity. The battery core 3 is disposed in the potting cavity and connected to the mounting surface 11. The coil 4 is wound around the battery core 3 along a center line perpendicular to the mounting surface 11. The thermally conductive adhesive is disposed in the potting cavity and at least fills the gap between the mounting surface 11 and the coil 4. The connector 5 is disposed on the base plate 1 and located outside the potting cavity. The connector 5 is electrically connected to the coil 4 and is used for electrical connection with external devices.

[0035] Optionally, the base plate 1 can be a square plate, and the base plate 1 has mounting holes at its four corners. By passing a connector through the mounting holes, the base plate 1 is fixed to the cold plate body 201, so that the base plate 1 is in contact with the first heat dissipation surface 202, thereby enabling the base plate 1 to achieve heat dissipation by contacting the first heat dissipation surface 202. The side of the base plate 1 facing away from the first heat dissipation surface 202 is the mounting surface 11.

[0036] The battery cell column 3 is connected to the mounting surface 11, and the battery cell column 3 is arranged in a direction perpendicular to the mounting surface 11, so that the battery cell column 3 has a center line perpendicular to the mounting surface 11. The coil 4 can be wound around the battery cell column 3 along the center line. The coil 4 includes multiple conductive coils, which can be arranged in a direction perpendicular to the mounting surface 11. Thus, among the multiple conductive coils, a number of conductive coils will be set closer to the mounting surface 11, that is, a number of conductive coils will be closer to the first heat dissipation surface 202. Thermal conductive adhesive is filled in the gap between the mounting surface 11 and the coil 4, so that the coil 4 can be wrapped by the thermal conductive adhesive and heat can be directly transferred through the thermal conductive adhesive, so that the conductive coils set close to the mounting surface 11 can dissipate heat quickly, thereby effectively improving the heat dissipation efficiency of the entire reactance 100. In addition, the coil 4 can be easily connected to external devices through the wiring lug 5.

[0037] Combination Figure 3 and Figure 6As shown, in some embodiments, the electronic control device 200 further includes a first power connector 204, which is mounted on the cold plate body 201. The first wiring portion 52 of the wiring ear 5 is electrically connected to the coil 4. The second wiring portion 53 of the wiring ear 5 is spaced apart from the first heat dissipation surface 202 and is electrically connected to the first power connector 204.

[0038] Optionally, the cold plate body 201 is provided with a first power connection opening, a first power connection socket 204 passes through the first power connection opening, and the first power connection socket 204 seals the first power connection opening. The first end of the first power connection socket 204 extends from the first heat dissipation surface 202. The second wiring portion 53 of the wiring ear 5 is electrically connected to the first end of the first power connection socket 204. The second end of the first power connection socket 204 is located on the side of the cold plate body 201 away from the capacitor, and the second end of the first power connection socket 204 can be electrically connected to the drive board. The first wiring portion 52 of the wiring ear 5 is electrically connected to the coil 4, so that the capacitor and the drive board located on opposite sides of the cold plate body 201 can be electrically connected through the first power connection socket 204. This allows the capacitor and the drive board to be located on opposite sides of the cold plate body 201, making use of the space on both sides of the cold plate body 201 and improving heat dissipation efficiency.

[0039] In some embodiments, the electronic control device 200 further includes a thermal pad connected to the first heat dissipation surface 202 and located between the base plate 1 and the first heat dissipation surface 202. The base plate 1 can exchange heat with the cold plate body 201 through the thermal pad, thereby further improving heat dissipation efficiency.

[0040] In this embodiment, the thermal pad can be a thin sheet made of aluminum. Aluminum has good thermal conductivity, which can increase the heat transfer efficiency between the base plate 1 and the cold plate body 201. In other embodiments, the thermal pad can be formed by the curing of thermally conductive adhesive. The thermally conductive adhesive can fill the gap between the base plate 1 and the cold plate body 201, making the base plate 1 and the cold plate body 201 fit more tightly and improving the thermal conductivity.

[0041] Please see Figure 5 In some embodiments, the coil 4 has a first side surface 41 disposed toward the mounting surface 11, the first side surface 41 being disposed parallel to the mounting surface 11, and thermally conductive adhesive filling at least the gap between the mounting surface 11 and the first side surface 41.

[0042] Optionally, the first side 41 of the coil 4 is arranged parallel to the mounting surface 11, so that the thermally conductive adhesive can be evenly filled in the gap between the mounting surface 11 and the first side 41. The first side 41 and the mounting surface 11 can transfer heat more evenly. When the base plate 1 is attached to the first heat dissipation surface 202, the first side 41 of the coil 4 can be arranged parallel to the first heat dissipation surface 202. The heat generated by the coil 4 can be evenly transferred to the cold plate body 201 for heat dissipation, further improving the heat dissipation efficiency.

[0043] Please see Figure 5 In some embodiments, the coil 4 also has a second side surface 42 disposed opposite to the mounting surface 11, and a peripheral side surface 43 located between the first side surface 41 and the second side surface 42. The peripheral side surface 43 extends around the center line, and thermally conductive adhesive is also filled between the peripheral side surface 43 and the housing 2, and between the second side surface 42 and the housing 2.

[0044] Optionally, the second side 42 and the first side 41 are opposite sides of the coil 4 along the direction perpendicular to the mounting surface 11. The peripheral side 43 is formed by splicing the surfaces of multiple wires of the coil 4. Thermal conductive adhesive is also filled between the peripheral side 43 and the housing 2, and between the second side 42 and the housing 2, so that the thermal conductive adhesive can immerse the entire coil 4. The heat generated by the entire coil 4 can be directly transferred to the base plate 1 through the thermal conductive adhesive. The base plate 1 then transfers the heat to the cold plate body 201 for heat dissipation, which can further improve the heat dissipation efficiency.

[0045] For easier application of thermally conductive adhesive, please refer to [link / reference needed]. Figure 5 In some embodiments, a glue-filling port 12 is provided on the base plate 1, and the glue-filling port 12 is connected to the glue-filling cavity. The thermal conductive adhesive is filled into the glue-filling cavity from the glue-filling port 12, which can make the liquid level of the thermal conductive adhesive gradually rise along the direction from the first side 41 to the second side 42 until the thermal conductive adhesive submerges the entire coil 4 and then the glue filling stops, which can reduce the waste of thermal conductive adhesive.

[0046] For easy electrical connection of coil 4 to external devices, please refer to [link / reference]. Figure 5 In some embodiments, the base plate 1 is provided with a wire hole 13, which communicates with the potting cavity. The reactance 100 also includes a connecting wire 6, which passes through the wire hole 13. The first end of the connecting wire 6 is located inside the potting cavity and is electrically connected to the coil 4. The second end of the connecting wire 6 is located outside the potting cavity and is electrically connected to the terminal lug 5.

[0047] Optionally, before filling with thermally conductive adhesive, the connecting wire 6 is threaded through the wire hole 13, and the connecting wire 6 and the wire hole 13 can form a seal, thereby preventing the thermally conductive adhesive from leaking from the wire hole 13 during the filling process. After the thermally conductive adhesive solidifies, it can fix the first end of the connecting wire 6 in the filling cavity, making the connection between the connecting wire 6 and the coil 4 more stable. The second end of the connecting wire 6 is located outside the filling cavity and is electrically connected to the wiring ear 5, which can be connected to external devices, thus making it easy to electrically connect the coil 4 to external devices.

[0048] Please see Figure 5 and Figure 7 In some embodiments, the reactor 100 further includes a terminal block 7 connected to the base plate 1, the terminal block 7 defining a plug-in channel 701 extending in a direction perpendicular to the mounting surface 11.

[0049] The connector 5 includes a connector body 51, a first connector portion 52, and a second connector portion 53. The connector body 51 is movably disposed in the insertion channel 701 so that the connector body 51 can move relative to the connector 7 in a direction perpendicular to the mounting surface 11. The first connector portion 52 is connected to the first end of the connector body 51 and is located outside the insertion channel 701. The first connector portion 52 is electrically connected to the coil 4. The second connector portion 53 is connected to the second end of the connector body 51 and is located outside the insertion channel 701. The second connector portion 53 is used for electrical connection with external devices.

[0050] It should be noted that due to inevitable installation errors during the manufacturing process, the height at which the first power connector 204 extends relative to the first heat dissipation surface 202 of the cold plate body 201 may deviate. When the wiring ear 5 is connected to the first power connector 204, abnormal connection may occur. For example, if the height at which the first power connector 204 extends relative to the first heat dissipation surface 202 is too high, the first power connector 204 may interfere with the wiring ear 5. Or, if the height at which the first power connector 204 extends relative to the first heat dissipation surface 202 is too low, a distance may be left between the first power connector 204 and the wiring ear 5, preventing the wiring ear 5 from connecting to the first power connector 204.

[0051] In this embodiment, by providing a plug-in channel 701 on the terminal block 7 and extending the plug-in channel 701 in a direction perpendicular to the mounting surface 11, the wiring body 51 is movably inserted through the plug-in channel 701, so that the wiring body 51 can move relative to the terminal block 7 in a direction perpendicular to the mounting surface 11. The first end and the second end of the wiring body 51 extend from the opposite ends of the plug-in channel 701, so that the wiring body 51 can drive the first wiring part 52 and the second wiring part 53 to move in a direction perpendicular to the mounting surface 11.

[0052] More specifically, when the capacitor is mounted on the cold plate body 201, the first terminal block 204 is inserted through the cold plate body 201 in a direction perpendicular to the first heat dissipation surface 202. That is, the first terminal block 204 protrudes from the cold plate body 201 in a direction perpendicular to the first heat dissipation surface 202. The mounting surface 11 is parallel to the first heat dissipation surface 202. When the wiring body 51 is moved in a direction perpendicular to the mounting surface 11, the second wiring part 53 can be moved closer to or further away from the first terminal block 204. In this way, the distance between the second wiring part 53 and the first terminal block 204 can be adjusted. In this way, even if there is a height deviation of the first terminal block 204, its adverse effects can be eliminated, so that the second wiring part 53 can be connected normally with the first terminal block 204, thereby preventing abnormal connection.

[0053] Please see Figure 8 and Figure 9 In some embodiments, the first connector 52 includes a first clamping plate 521 and a second clamping plate 522. The first clamping plate 521 is connected to the first end of the connector body 51 and is located outside the insertion channel 701. The second clamping plate 522 is connected to the first clamping plate 521, and the second clamping plate 522 and the first clamping plate 521 cooperate to form a clamping groove 523. The clamping groove 523 is used to accommodate one end of the connector 6 located outside the potting cavity, so that the first clamping plate 521 and the second clamping plate 522 can clamp the connector 6.

[0054] In this embodiment, both the first clamping plate 521 and the second clamping plate 522 are elastic. The first clamping plate 521 is connected to the first end of the wiring body 51, and the second clamping plate 522 is connected to the first clamping plate 521. Alternatively, the wiring body 51, the first clamping plate 521, and the second clamping plate 522 can be integrally formed. The first clamping plate 521 is a flat plate, and the second clamping plate 522 is a bent plate, which facilitates the formation of a clamping groove 523 between the first clamping plate 521 and the second clamping plate 522. The width of the clamping groove 523 along the first clamping plate 521 toward the second clamping plate 522 is less than the diameter of the connecting wire 6. Thus, when the connecting wire 6 is located in the clamping groove 523, the first clamping plate 521 and the second clamping plate 522 can deform and generate a clamping force to fix the connecting wire 6 in the clamping groove 523, so that the connecting wire 6 is connected to the wiring lug 5.

[0055] Please see Figure 7 and Figure 9 In some embodiments, the second wiring section 53 includes a wiring board 531, which is connected to the second end of the wiring body 51 and is located outside the plug-in channel 701. The wiring board 531 is provided with a wiring hole 532 for electrical connection with an external device.

[0056] Optionally, the terminal block 531 can be arranged parallel to the first heat dissipation surface 202, and the axis of the wiring hole 532 can be parallel to the direction perpendicular to the first heat dissipation surface 202, so that the conductive post on the first terminal block 7 can pass through the wiring hole 532, thereby electrically connecting the second wiring part 53 to the first terminal block 7, and enabling the wiring ear 5 to be electrically connected to an external device. In some other embodiments, the first terminal block 7 may have a plug hole, and the connector may be sequentially inserted into the wiring hole 532 and the plug hole, so that the wiring lug 5 is electrically connected to the first terminal block 7.

[0057] Please see Figures 7 to 10 In some embodiments, the terminal block 7 includes a connecting base 71, a support body 72, and a connector 73. The connecting base 71 is connected to the base plate 1. One end of the support body 72 is connected to the connecting base 71 and extends in a direction perpendicular to the mounting surface 11. The connector 73 is connected to the end of the support body 72 away from the connecting base 71 and the connector 73 and the mounting surface 11 are located on the same side of the base plate 1. The connector 73 defines a plug-in channel 701. In a direction parallel to the mounting surface 11, the first end and the second end of the wiring body 51 are respectively arranged on opposite sides of the support body 72, and at least a portion of the wiring body 51 is located on the side of the connector 73 facing away from the connecting base 71.

[0058] Optionally, the terminal block 7 is made of insulating material, and the connecting base 71, the support body 72, and the connector 73 can be integrally formed. The wiring body 51 may include a first part, a second part, and a third part connected in sequence. The first part has a first end of the wiring body 51, passes through the plug-in channel 701, and extends toward the connecting base 71 to connect with the first wiring portion 52. The second part extends in a curved manner relative to the first part and is located on the side of the connector 73 facing away from the connecting base 71. The third part extends in a curved manner with the second part, has a second end of the wiring body 51, is located on the side of the support body 72 facing away from the first wiring portion 52, and extends toward the connecting base 71 to connect with the second wiring portion 53.

[0059] Thus, the wiring body 51 has a U-shaped structure, so that the first end and the second end of the wiring body 51 are located on opposite sides of the support body 72, which can facilitate the connection of the wiring ear 5 to the coil 4 and external equipment. The connector 73 can also limit the wiring body 51, so that the wiring body 51 can move within a certain range and prevent the wiring body 51 from detaching from the plug-in channel 701. In addition, it can also prevent the wiring body 51 from driving the second wiring part 53 to the side of the base plate 1 facing away from the mounting surface 11, thereby preventing the second wiring part 53 from interfering with the cold plate body 201.

[0060] Please see Figure 7 In some embodiments, the side of the connector 73 facing away from the connector base 71 is provided with a first limiting structure 731. The first limiting structure 731 is used to limit the wiring body 51 to move in a direction parallel to the mounting surface 11.

[0061] More specifically, the first limiting structure 731 includes multiple limiting blocks 7311, all of which are disposed on the side of the connector 73 facing away from the connecting base 71. At least two limiting blocks 7311 are arranged in a direction parallel to the mounting surface 11 to form a limiting groove between the two limiting blocks 7311. The second part of the wiring body 51 is located in the limiting groove. When the second part shakes in a direction parallel to the mounting surface, the second part abuts against the two limiting blocks 7311 on its opposite sides parallel to the mounting surface, thereby limiting the movement of the wiring body 51 in a direction parallel to the mounting surface 11 and thus limiting the shaking amplitude of the wiring body 51 and further reducing the degree of shaking of the wiring body 51.

[0062] Please see Figure 7 In some embodiments, a second limiting structure 721 is provided on the side of the support body facing away from the first wiring portion 52. The second limiting structure 721 is used to limit the wiring body 51 to move in a direction parallel to the mounting surface 11.

[0063] Optionally, the second limiting structure 721 includes two second limiting flanges, which extend in a direction perpendicular to the mounting surface 11. The third part of the wiring body 51 is located between the two second limiting flanges. The second limiting flanges can abut against the third part of the wiring body 51 to restrict the movement of the wiring body 51 in a direction parallel to the mounting surface 11, thereby further preventing the wiring body 51 from shaking. The two second limiting flanges can also guide the wiring body 51 to move in a direction perpendicular to the mounting surface 11, so that the wiring body 51 can move more stably in a direction perpendicular to the mounting surface 11.

[0064] Please see Figure 5 and Figure 10 In some embodiments, the base plate 1 has a bending strip 14, and the connecting base plate 1 has a snap-fit ​​groove 711, in which the bending strip 14 snaps into the snap-fit ​​groove 711 to connect the connecting base 71 to the base plate 1.

[0065] Optionally, the edge of the base plate 1 may be provided with a bending strip 14. The bending strip 14 may be a metal strip, which gives the bending strip 14 good toughness, and the bending strip 14 is easy to bend and can be stable in the bent state. The bending strip 14 can be bent and the bent part of the bending strip 14 can be inserted into the snap-fit ​​groove 711, so that the bending strip 14 can connect the connecting base 71 to the base plate 1, which is very convenient to install.

[0066] Please see Figure 8 and Figure 9 In some embodiments, the first end of the wiring body 51 is provided with a limiting member 511. The insertion channel 701, the limiting member 511 and the mounting surface 11 are arranged in sequence at intervals along the direction perpendicular to the mounting surface 11, so that there can be a certain distance between the limiting member 511 and the connector 73. This distance allows the wiring body 51 to move along the direction perpendicular to the mounting surface 11, ensuring that the height of the wiring lug 5 can be adjusted along the direction perpendicular to the mounting surface 11, thereby offsetting the height deviation of the first electrical connector 204.

[0067] When the wiring body 51 moves away from the mounting surface 11, the wiring body 51 can drive the limiting member 511, the first wiring part 52 and the second wiring part 53 to move synchronously. When the limiting member 511 moves to abut against the connector 73, it can restrict the wiring body 51 from continuing to move away from the mounting surface 11, thereby restricting the first wiring part 52 from extending into the plug channel 701, and also preventing the wiring ear 5 from disengaging from the terminal block 7.

[0068] Optionally, two limiting members 511 are disposed on the first part of the wiring body 51, and both limiting members 511 are located outside the plug-in channel 701. The two limiting members 511 are arranged on opposite sides of the first part in a direction parallel to the mounting surface 11. When the wiring body 51 moves away from the connecting base 71 and moves the two limiting members 511 to abut against the connector 73, the wiring body 51 can be restricted from continuing to move away from the connecting base 71, thereby preventing the first wiring part 52 from extending into the plug-in channel 701.
