Description

Technical Field

[0001] The present invention relates to the technical field of reactors, and in particular to a three-dimensional magnetically controlled reactor and a temperature control device thereof. Background Art

[0002] A reactor is an electronic component that is mainly used to introduce inductance into a circuit to resist changes in the magnitude and direction of current. It has multiple functions in the power system, including limiting short-circuit current, stabilizing voltage, reactive power compensation, and phase shifting.

[0003] The magnetically controlled reactor is a type of reactor that mainly controls the coupling state between capacitors and inductors through magnetic fields, thereby changing the electrical characteristics of the circuit and achieving circuit regulation. It is widely used in power systems, electrical transmission, industrial control and other fields.

[0004] In the related art, for example, Chinese patent CN105261466B discloses a magnetically controlled adjustable reactor, which uses the principle of transformer impedance transformation to wind a reactor and a transformer together in a certain ratio, which is equivalent to connecting a reactor and a transformer in series, and changing the secondary impedance of the transformer to adjust the primary impedance. The tiny impedance transformation is easy to achieve, and the reactance rate K can be transformed from 4.5% to 6%, and it can also be fine-tuned within ±10% of the determined reactance rate K to make the adjustment more precise. In addition to the adjustable impedance, the wiring is no different from that of an ordinary reactor during operation. After the impedance is adjusted at the factory, its impedance changes in direct proportion to the harmonics of the power grid.

[0005] In the production process of existing reactors, in order to reduce magnetic leakage, the windings usually need to be closely fitted, which causes friction between adjacent windings during the winding process, which makes it easy for the insulation layer to wear. In addition, the reactor will vibrate during operation. The vibration frequency is very high, which will also cause wear of the insulation layer. When the reactor is dissipating heat, the heat dissipation oil or air cooling can only dissipate heat on the outer surface of the reactor, so the heat dissipation effect is not good. Summary of the invention

[0006] Based on this, it is necessary to provide a three-dimensional magnetically controlled reactor and a temperature control device thereof to address the problems of easy wear of the winding insulation layer and poor heat dissipation effect of the current reactor.

[0007] The above purpose is achieved through the following technical solutions: A three-dimensional magnetically controlled inductor, the three-dimensional magnetically controlled inductor comprising a frame, an iron core being vertically arranged on the frame, heat dissipation fins, a liquid cooling tube and a winding being spirally wound on the iron core in sequence, the heat dissipation fins being arranged as a C-shaped strip structure with an opening arranged outward; the liquid cooling tube and the winding are both inserted into the heat dissipation fins, and the liquid cooling tube is located on the inner side of the winding, the liquid cooling tube is filled with a heat absorbing fluid, and the heat absorbing fluid is configured to absorb the heat generated by the iron core; when the winding is wound in multiple layers, the heat dissipation fins are inserted between the outermost winding and the winding adjacent thereto, and the liquid cooling tube is inserted between the heat dissipation fins and the outermost winding.

[0008] Furthermore, the heat absorbing fluid includes a cooling liquid.

[0009] Furthermore, the three-dimensional magnetically controlled inductor also includes a radiator, a delivery pump and a cooling system, the liquid inlet of the liquid cooling tube is connected to the discharge end of the delivery pump, the liquid outlet of the liquid cooling tube is connected to the liquid receiving end of the radiator, and the liquid outlet end of the radiator is connected to the liquid extraction end of the delivery pump; the cooling system is configured to reduce the temperature of the radiator.

[0011] Furthermore, the throttling component includes a thermal expansion valve and an electronic expansion valve.

[0012] Furthermore, the cooling system also includes a fan.

[0013] Furthermore, there are a plurality of the iron cores, and each of the iron cores is spirally wound with the heat dissipation fins, the liquid cooling tube and the winding in sequence.

[0014] The present invention also provides a temperature control device for a three-dimensional magnetically controlled inductor, which is applied to a three-dimensional magnetically controlled inductor. The temperature control device for the three-dimensional magnetically controlled inductor includes an induction component and a control component. The induction component is configured to sense the temperature of the three-dimensional magnetically controlled inductor; the control component is configured to start a delivery pump when the temperature of the three-dimensional magnetically controlled inductor is greater than a first preset temperature; and to start a cooling system when the temperature of the three-dimensional magnetically controlled inductor is greater than a second preset temperature; wherein the second preset temperature is greater than the first preset temperature.

[0015] Furthermore, the sensing element includes an infrared temperature sensor.

The temperature control device of the three-dimensional magnetically controlled inductor is applied to the three-dimensional magnetically controlled inductor and is used to control the temperature of the three-dimensional magnetically controlled inductor. When the three-dimensional magnetically controlled inductor is in use, the heat dissipation fins can isolate the winding and the iron core from each other, thereby reducing the wear of the insulating layer on the winding. The liquid cooling pipe can not only dissipate heat from the inside to the outside, but also improve the heat dissipation effect. When a heat-absorbing fluid is passed into the liquid cooling pipe, the liquid cooling pipe expands and can simultaneously press the heat dissipation fins and the winding. On the one hand, it can increase the contact area between the iron core and the heat dissipation fins and improve the heat dissipation efficiency. On the other hand, it can make the winding generate stress and not easy to shake, thereby not easy to wear the insulating layer on the winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0022] like Figures 1 to 7 As shown, a three-dimensional magnetically controlled inductor provided by an embodiment of the present invention includes a frame 1, an iron core 2 is vertically arranged on the frame 1, and heat sink fins 3, liquid cooling tubes 4 and windings 5 ​​are spirally wound on the iron core 2 in sequence, and the heat sink fins 3 are arranged as a C-shaped strip structure with an opening facing outward; the liquid cooling tubes 4 and the windings 5 ​​are both inserted into the heat sink fins 3, and the liquid cooling tubes 4 are located on the inner side of the windings 5, and the liquid cooling tubes 4 are filled with a heat absorbing fluid, and the heat absorbing fluid is configured to absorb the heat generated by the iron core 2.

[0023] Specifically in this embodiment, Figure 2 As shown, the frame 1 is configured to be composed of an upper support plate 11 and a lower support plate 12, the upper support plate 11 and the lower support plate 12 are both configured as plate-like structures, and when in use, the plate surfaces are configured to be parallel to the horizontal plane, and the upper support plate 11 and the lower support plate 12 are arranged at intervals in the vertical direction; the iron core 2 is configured as a columnar structure, and when installed, the top end is configured to be vertically connected to the bottom of the upper support plate 11, and the bottom end is vertically connected to the top of the lower support plate 12; as shown Figure 4As shown, the heat dissipation fin 3 is composed of a main body part 31 and two split parts 32. The cross-sectional shape of the main body part 31 is set as a "匚" shape, and the cross-sectional shapes of the two split parts 32 are set as "八" shapes, and they are symmetrically arranged at both ends of the opening of the main body part 31. The large mouths of the two split parts 32 face inward, and the small mouths face outward; as Figure 6 shown, the winding 5 is set as a vertically arranged strip structure, and when inserted inside the heat dissipation fin 3, its position is restricted by the constriction formed by the two split parts 32.

[0024] When the three-dimensional magnetically controlled reactor is in use, the heat dissipation fins 3 can isolate the winding 5 and the iron core 2 from each other, thereby reducing the wear of the insulating layer on the winding 5; and the liquid cooling pipe 4 can not only dissipate heat from the inside to the outside, but also improve the heat dissipation effect. When a heat-absorbing fluid is introduced into the liquid cooling pipe 4, the liquid cooling pipe 4 expands and can simultaneously press against the heat dissipation fin 3 and the winding 5. On the one hand, it can increase the contact area between the iron core 2 and the heat dissipation fin 3, improving the heat dissipation efficiency. On the other hand, it can make the winding 5 generate stress and not easily shake, and thus not easily wear the insulating layer on the winding 5.

[0025] In some embodiments, the heat-absorbing fluid can be set to include a coolant.

[0026] In a further embodiment, to facilitate the provision of the circulating power of the coolant, the three-dimensional magnetically controlled reactor is set to further include a radiator, a delivery pump, and a cooling system. The liquid inlet of the liquid cooling pipe 4 is connected to the liquid discharge end of the delivery pump, the liquid outlet of the liquid cooling pipe 4 is connected to the liquid receiving end of the radiator, and the liquid discharge end of the radiator is connected to the liquid suction end of the delivery pump; the cooling system is configured to be able to reduce the temperature of the radiator.

[0027] Specifically in this embodiment, to facilitate the connection between the liquid cooling pipe 4 and the delivery pump and the radiator, as Figure 4 shown, connectors 41 are provided at both ends of the liquid cooling pipe 4, and the connectors 41 are set to be threadedly connected to the pipes used on the delivery pump and the radiator during installation.

[0028] During use, the delivery pump is started, and the delivery pump drives the coolant to circulate between the liquid cooling pipe 4 and the radiator. Among them, the coolant inside the liquid cooling pipe 4 can absorb the heat generated by the iron core 2 to reduce the working temperature of the three-dimensional magnetically controlled reactor and ensure its working performance; the coolant in the radiator can release the heat generated by the iron core 2 to facilitate the preparation for absorbing the heat generated by the iron core 2 next time.

[0029] In a further embodiment, the cooling system can be set to include a compressor, a condenser, a throttling component, and an evaporator. The exhaust port of the compressor is connected to the condenser, the suction port of the compressor is connected to the evaporator, the condenser is connected to the liquid inlet end of the throttling component, the liquid outlet end of the throttling component is connected to the evaporator, and the evaporator is arranged on the radiator.

[0030] During use, the refrigerant gas in the compressor first enters the condenser. After releasing heat through the condenser, it is throttled, cooled and reduced in pressure through the throttling component to become a refrigerant with gas and liquid coexisting phases. It then absorbs heat from the radiator through the evaporator and returns to the compressor, completing a refrigeration cycle.

[0031] In a further embodiment, the throttling component is configured to include a thermal expansion valve and an electronic expansion valve, which can be selected according to needs; wherein the thermal expansion valve is a key component used in a refrigeration system, and its main function is to control the superheat of the evaporator outlet by adjusting the refrigerant flow rate, thereby ensuring that the refrigerant in the evaporator is completely evaporated and preventing liquid refrigerant from entering the compressor to cause liquid hammer. It is usually installed on the liquid inlet pipe of the evaporator to play a role of throttling and reducing the pressure, throttling and reducing the pressure of the high-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure vapor-liquid mixture to facilitate evaporation in the evaporator; the working principle of the thermal expansion valve is to sense the superheat of the refrigerant vapor at the evaporator outlet based on the temperature sensing package. When the superheat increases, the pressure in the temperature sensing package also increases, and is transmitted to the space above the diaphragm through the capillary tube, causing the diaphragm to elastically deform and push the actuator to adjust the valve opening, thereby controlling the flow of the refrigerant.

[0032] An electronic expansion valve is a throttling element used in a refrigeration system. It adjusts the refrigerant flow entering the refrigeration unit through electronic control, thereby achieving precise control of the liquid supply to the evaporator. Its working principle is to adjust the refrigerant flow through the control of the valve body. The electronic expansion valve has the characteristics of fast response, quick and convenient adjustment, and flexible action. It can be precisely adjusted within the range of 10% to 100%. Compared with traditional thermal expansion valves, electronic expansion valves have significant advantages: first, electronic expansion valves have faster response speeds, and it only takes a few seconds to go from fully closed to fully open. Second, electronic expansion valves can make extremely small adjustments, so that the refrigerant flow fluctuates little, thereby maintaining a basically constant superheat under variable operating conditions. In addition, electronic expansion valves can also set opening and closing characteristics and speeds according to different product characteristics.

[0033] In other embodiments, the cooling system may also be configured to include a fan.

[0034] During use, the fan can blow air to absorb the heat of the radiator by accelerating the flow of air around the radiator.

[0035] In other embodiments, the heat absorbing fluid may also be configured to include a refrigerant.

[0036] Specifically in this embodiment, the heat dissipation efficiency can be improved by using the radiator directly as an evaporator in the cooling system so that the heat of the iron core 2 is directly absorbed by the refrigerant.

[0037] In other embodiments, there are multiple iron cores 2, and each iron core 2 is spirally wound with heat dissipation fins 3, liquid cooling tubes 4 and windings 5 ​​in sequence; when in use, the multiple iron cores 2 achieve precise control of the reactance value and effective management of the power system by adjusting the saturation degree and increasing the magnetic flux.

[0038] Specifically in this embodiment, the number of the iron cores 2 is set to three as an example. Figure 2 As shown, the three iron cores 2 are arranged at equal intervals along the length direction of the upper support plate 11; and the liquid inlets of all the liquid cooling tubes 4 are arranged in parallel to facilitate the introduction of the heat-absorbing fluid into all the liquid cooling tubes 4 at the same time, and the liquid outlets of all the liquid cooling tubes 4 are arranged in parallel to facilitate the discharge of the heat-absorbing fluid in all the liquid cooling tubes 4 at the same time, so as to facilitate unified treatment.

[0039] In other embodiments, when the winding 5 is wound in multiple layers, the heat sink fin 3 is inserted between the outermost winding 5 and the adjacent winding 5 , and the liquid cooling tube 4 is inserted between the heat sink fin 3 and the outermost winding 5 .

[0040] During use, the heat dissipation fins 3 can isolate the outermost winding 5 and the inner winding 5 from each other, reducing the wear of the insulation layer on the outermost winding 5 and the inner winding 5; the liquid cooling tube 4 can not only realize two-way heat dissipation, but also improve the heat dissipation effect, and when the liquid cooling tube 4 is passed into the heat absorbing fluid, the liquid cooling tube 4 expands and can simultaneously press the heat dissipation fins 3 and the outermost winding 5, on the one hand, it can increase the contact area between the inner winding 5 and the heat dissipation fins 3, and improve the heat dissipation efficiency, on the other hand, it can make the winding 5 produce stress and not shake easily, and thus it is not easy to wear the insulation layer on the winding 5.

[0041] An embodiment of the present invention also provides a temperature control device for a three-dimensional magnetically controlled inductor, which is applied to a three-dimensional magnetically controlled inductor. The temperature control device of the three-dimensional magnetically controlled inductor is configured to include an induction component and a control component 6. The induction component is configured to sense the temperature of the three-dimensional magnetically controlled inductor; the control component 6 is configured to start a delivery pump when the temperature of the three-dimensional magnetically controlled inductor is greater than a first preset temperature; and to start a cooling system when the temperature of the three-dimensional magnetically controlled inductor is greater than a second preset temperature; wherein the second preset temperature is greater than the first preset temperature.

[0042] Specifically in this embodiment, the sensing element may be configured to include an infrared temperature sensor so as to be able to measure the temperature of the reactor in real time.

[0043] More specifically, the control element 6 can be set as a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD) or any combination thereof; the control element 6 can also be other devices with processing functions, such as circuits, devices or software modules; in order to facilitate receiving signals from infrared temperature sensors and sending signals to the delivery pump and the cooling system, the control element 6 is configured to be connected to the infrared temperature sensor, the delivery pump and the cooling system by wire or wirelessly.

[0044] Taking the connection mode of the communication connection as Wi-Fi connection as an example, the control component 6 scans the wireless signal of the Wi-Fi hotspot (also known as a wireless router) through the communicator, and then establishes a communication connection with the Wi-Fi hotspot; after establishing a communication connection with the Wi-Fi hotspot, the controller of the display device can query other devices that have established a communication connection with the Wi-Fi hotspot; if the other devices that have established a communication connection with the Wi-Fi hotspot include an infrared temperature sensor, a delivery pump, and a cooling system, then a communication connection can be established between the controller and the infrared temperature sensor, the delivery pump, and the cooling system through the Wi-Fi hotspot.

[0045] Exemplarily, the first preset temperature can be set to 40°C, and the second preset temperature can be set to 70°C. When the temperature of the three-dimensional magnetically controlled inductor is greater than 40°C, it means that the convection heat dissipation through the natural environment is not sufficient to lower the temperature of the three-dimensional magnetically controlled inductor. At this time, the delivery pump can be started to meet the heat dissipation demand of the three-dimensional magnetically controlled inductor by delivering the heat-absorbing fluid; when the temperature of the three-dimensional magnetically controlled inductor is greater than 70°C, it means that the heat absorption capacity of the heat-absorbing fluid is insufficient. At this time, the cooling system can be started to quickly reduce the temperature of the three-dimensional magnetically controlled inductor by increasing the heat absorption capacity of the heat-absorbing fluid to ensure its working performance.

[0046] It is understandable that even if the liquid inside the liquid cooling tube 4 does not flow, the pressure of the liquid inside the liquid cooling tube 4 will not decrease, thereby preventing the change in fluid pressure inside the liquid cooling tube 4 from causing a change in the volume of the liquid cooling tube 4, causing the winding 5 to move inside the heat sink fin 3 and cause wear.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
