[0002] Vertical winding reactor is a kind of electrical equipment for power system, its main function is to adjust and control current, voltage and other parameters, vertical winding reactor usually includes box, magnetic column and coil around magnetic column. Because vertical winding reactor will generate a large amount of heat in the working process, so it usually needs to adopt air cooling or water cooling to the vertical winding reactor inside heat dissipation. Since the cost of water cooling heat dissipation mode is high, so the prior art adopts the mode of air cooling to vertical winding reactor heat dissipation.
[0003] The vertical winding reactor of air-cooled heat dissipation of prior art is usually cooled by the way that the external cold air flows into the box, the cold air is heat-dissipated to the coil in the box, and the hot air absorbing heat flows out from the box. Because the air duct in the box is simple, the heat dissipation air flows quickly through the box, and the coil cannot be well heat-dissipated, and the heat dissipation effect is very poor.
[0004] Therefore, it is urgent to develop a vertical winding reactor with simple structure and good heat dissipation effect. UTILITY MODEL CONTENT
[0005] The utility model discloses a vertical winding reactor with simple structure and good heat dissipation effect to solve the above technical problems.
[0006] A vertical winding reactor comprises a box with an air inlet and an air outlet, a magnetic column arranged in the box, and a coil arranged around the magnetic column. A fan is arranged at a position corresponding to the air outlet on the outside of the box. A first baffle is arranged between the air inlet and the air outlet in the box and embedded in the coil from one side end of the coil.
[0007] Preferably, the other side end of the coil is embedded in a second baffle arranged between the air inlet and the air outlet from the side of the magnetic column axial of the first baffle in the box.
[0008] Preferably, the first baffle and the second baffle are embedded in more than half of the thickness of the coil.
[0009] Preferably, the first baffle and the second baffle are provided with a U-shaped groove, and the magnetic column is located in the U-shaped groove.
[0010] Preferably, the first baffle and the second baffle are arranged in parallel, and the first baffle and the second baffle are respectively at an angle of 20 degrees to 150 degrees with the magnetic column.
[0011] Preferably, the first baffle and the second baffle each have four ends, one end of the first baffle is suspendedly embedded in the coil, and at least one of the remaining ends of the first baffle is fixed to the inner wall of the box; one end of the second baffle is suspendedly embedded in the coil, and at least one of the remaining ends of the second baffle is fixed to the inner wall of the box.
[0012] Preferably, the first baffle is an insulating baffle, and the second baffle is an insulating baffle; the coil is a flat coil, a square coil or a circular coil.
[0013] Preferably, the number of the magnetic columns of the box is three, the three magnetic columns are arranged in parallel, the three magnetic columns each surround the coil, the first baffles corresponding to the magnetic columns are arranged on the same horizontal line, and the three first baffles are integrally formed as one piece; the second baffles corresponding to the magnetic columns are arranged on the same horizontal line, and the three second baffles are integrally formed as one piece.
[0014] Preferably, the magnetic columns are vertically arranged, the air inlet is arranged at the bottom or the lower part of one side face of the box, and the air outlet is arranged at the top or the upper part of one side face of the box.
[0015] Preferably, the magnetic columns are horizontally arranged, the air inlet is arranged at the left side of the box, and the air outlet is arranged at the right side of the box; or the air inlet and the air outlet are arranged at two ends of the front side of the box, respectively.
[0016] The vertical reactor of the utility model is provided with the first baffle embedded in the coil from one side end of the coil between the air inlet and the air outlet in the box. When running, the fan at the position corresponding to the air outlet is started, and under the suction force of the fan, the cold air outside the box enters the box through the air inlet, the cold air flows to the direction of the air outlet, and the coil between the air outlet and the air inlet is cooled; because the first baffle embedded in the coil from one side end of the coil is arranged between the air inlet and the air outlet in the box, when the originally straight-flowing cold air meets the first baffle, the airflow flows from one end of the first baffle under the action of the first baffle, continues to cool the coil behind the first baffle, and finally, the hot air absorbing the heat of the coil flows out from the air outlet under the suction force of the fan.
[0017] This utility model's vertically wound reactor incorporates a fan, accelerating airflow within the enclosure and improving heat dissipation efficiency and performance. Furthermore, the inclusion of a first baffle plate transforms the previously linear airflow within the enclosure into a zigzag flow, lengthening the airflow path and increasing the air's contact time with the coil. This allows the air more time to absorb heat from the coil and carry it away, significantly enhancing heat dissipation efficiency and resulting in excellent cooling performance. The first baffle plate in this vertically wound reactor design contributes to its simple structure and low cost. Attached Figure Description

[0024] The present invention will be further described in conjunction with the following embodiments and accompanying drawings:
[0025] A type of vertically wound reactor, such as Figures 1 to 5 As shown, it includes: a housing 12 with an air inlet 10 and an air outlet 11, a magnetic column 13 disposed inside the housing 12, a coil 14 disposed around the magnetic column 13, a fan 15 disposed at the corresponding position of the air outlet 11 on the outside of the housing 12, and a first baffle 16 disposed between the air inlet 10 and the air outlet 11 inside the housing 12, which is embedded into the coil 14 from one side end.
[0026] The utility model discloses a vertical winding reactor is provided with the first baffle 16 of embedding coil 14 from one side end of coil 14 between the air inlet 10 and the air outlet 11 in the box 12.
[0027] The utility model discloses a vertical winding reactor is provided with the first baffle 16 of embedding coil 14 from one side end of coil 14 between the air inlet 10 and the air outlet 11 in the box 12.
[0028] Preferably, as Figures 1 to 4As shown, the first baffle 16 in the box 12 is provided with a second baffle 17 embedded in the coil 14 from the other side end of the coil 14, and the second baffle 17 is arranged between the air inlet 10 and the air outlet 11. The direction of the dashed arrow in the figure is the direction of the air flow. The second baffle 17 is embedded in the coil 14 from the other side end of the coil 14. If the second baffle 17 is arranged on the air outlet 11 side of the first baffle 16, the air in the box 12 passes through the first baffle 16, and then encounters the second baffle 17 in the process of flowing towards the air outlet 11. Under the action of the second baffle 17, the air flow bypasses the second baffle 17 from one end of the second baffle 17, continues to dissipate heat for the coil 14 behind the second baffle 17, and finally, the hot air absorbing the heat of the coil 14 flows out from the air outlet 11 under the suction of the fan 15. Since the first baffle 16 is embedded in the coil 14 from one side end of the coil 14, and the second baffle 17 is embedded in the coil 14 from the other side end of the coil 14, an "S" shaped heat dissipation channel is formed in the box 12 by the first baffle 16 and the second baffle 17. Therefore, the air makes two times of turning motion under the action of the first baffle 16 and the second baffle 17, greatly increasing the flow path of the air in the box 12. Therefore, the arrangement of the second baffle 17 further increases the flow path of the air in the box 12, increases the flow time of the air in the box 12, that is, further increases the contact time of the air with the coil 14, so that the air has more time to absorb the heat of the coil 14, and then carries away more heat of the coil 14, thereby further improving the heat dissipation efficiency and greatly improving the heat dissipation effect. Of course, in some smaller standing reactors, if the space in the box 12 is small, only the first baffle needs to be arranged.
[0029] Preferably, the first baffle 16 and the second baffle 17 are embedded in more than half of the thickness of the coil 14. Embedding the first baffle 16 and the second baffle 17 in more than half of the thickness of the coil 14 can change the flow direction of more air in the box 12, the air turning path is long, which is conducive to increasing the flow path of the air in the box 12, increasing the flow time of the air in the box 12, and improving the heat dissipation efficiency.
[0030] Preferably, as shown in the figure, Figure 5 The first baffle 16 and the second baffle 17 are provided with a U-shaped groove 18, and the magnetic column 13 is located in the U-shaped groove 18. In this way, the first baffle 16 and the second baffle 17 can wrap the magnetic column 13 more, which can change the flow direction of more air in the box 12, the air turning path is long, which is conducive to increasing the flow path of the air in the box 12, increasing the flow time of the air in the box 12, and improving the heat dissipation efficiency.
[0031] Preferably, the first baffle 16 and the second baffle 17 are arranged in parallel, with the first baffle 16 and the second baffle 17 forming an angle of 20 degrees to 150 degrees with the vertical plane of the magnetic column 13, respectively. The parallel arrangement of the first baffle 16 and the second baffle 17 prevents sudden widening or narrowing of the airflow path, facilitating smooth airflow within the housing 12 and preventing heat accumulation, thus promoting heat dissipation. The 20-150 degree angle between the first baffle 16 and the second baffle 17 and the magnetic column 13 ensures that they form a certain angle. If the angle between the first baffle 16 and the second baffle 17 and the magnetic column 13 is too large or too small, i.e., the first baffle 16 and the second baffle 17 are almost parallel to the magnetic column 13, then the first baffle 16 and the second baffle 17 cannot effectively change the direction of airflow within the housing 12, resulting in poor heat dissipation. Therefore, the first baffle 16 and the second baffle 17 are at an angle of 20 degrees to 150 degrees to the vertical plane of the magnetic column 13, which helps to increase the path length of air flow in the coil 14 and the air flow time in the housing 12, thus ensuring higher heat dissipation efficiency.
[0032] Better, such as Figures 1 to 4 As shown, the first baffle 16 and the second baffle 17 each have four ends. One end of the first baffle 16 is suspended and embedded in the coil 14, and at least one end of the remaining ends of the first baffle 16 is fixed to the inner wall of the housing 12. One end of the second baffle 17 is suspended and embedded in the coil 14, and at least one end of the remaining ends of the second baffle 17 is fixed to the inner wall of the housing 12.
[0033] The first baffle 16 and the second baffle 17 each have four ends. At least one of the remaining ends of the first baffle 16 is fixed to the inner wall of the housing 12. That is, one, two, or three of the remaining ends of the first baffle 16 can be fixed to the inner wall of the housing 12 as needed. In this way, the air duct formed by the first baffle 16 and the inner wall of the housing 12 is conducive to the concentrated circulation of air in the housing 12 and to heat dissipation. Moreover, the fixing method of the first baffle 16 is very simple and does not require additional structure to fix the first baffle 16. The fixing is firm.
[0034] At least one of the remaining ends of the second baffle 17 is fixed to the inner wall of the housing 12. That is, one, two, or three of the remaining ends of the second baffle 17 can be fixed to the inner wall of the housing 12 as needed. In this way, the air duct formed by the second baffle 17 and the inner wall of the housing 12 is conducive to the concentrated circulation of air in the housing 12 and to heat dissipation. Moreover, the fixing method of the second baffle 17 is very simple, and no additional structure is needed to fix the second baffle 17. The fixing is firm.
[0035] Preferably, the first baffle plate 16 is an insulating baffle plate, and the second baffle plate 17 is an insulating baffle plate; the coil 14 is a flat coil 14 or a square coil 14 or a circular coil 14. Since the inner coil 14 of the vertical winding reactor is electrified, the first baffle plate 16 and the second baffle plate 17 are provided as insulating baffle plates, which can effectively prevent the arc discharge and avoid damage to the vertical winding reactor due to arc discharge. Specifically, the first baffle plate 16 and the second baffle plate 17 can be epoxy plates, which have good insulation effect and low cost, and of course can also be insulating baffle plates of other materials in the prior art. The coil 14 can be a flat coil 14 or a square coil 14 or a circular coil 14, which facilitates the embedding of the first baffle plate 16 and the second baffle plate 17 between layers, and of course the coil 14 can also be a coil of other shapes in the prior art.
[0036] Preferably, as shown in Figure 5 the number of magnetic columns 13 of the box body 12 is three, the three magnetic columns 13 are arranged in parallel, and the three magnetic columns 13 are all arranged around the coil 14. The first baffle plate 16 corresponding to each magnetic column 13 is arranged on the same horizontal line, and the three first baffle plates 16 are integrally formed as one piece. The second baffle plate 17 corresponding to each magnetic column 13 is arranged on the same horizontal line, and the three second baffle plates 17 are integrally formed as one piece. Three magnetic columns 13 are arranged in the box body 12, and the three magnetic columns 13 are all arranged around the coil 14, i.e. three groups of magnetic columns 13 and coils 14. In this way, the structure of the vertical winding reactor is more compact, and the three coils 14 can be respectively connected to external three-phase electricity. The three first baffle plates 16 are integrally formed as one piece, and the three second baffle plates 17 are integrally formed as one piece, so that the structure is more compact and simple; three first baffle plates 16 and three second baffle plates 17 do not need to be installed respectively, but only the integrally formed first baffle plate 16 and the first baffle plate 16 need to be installed, which is more simple and efficient, greatly improving the installation efficiency and saving the installation time.
[0037] Preferably, as shown in Figures 1 to 3 the magnetic column 13 is vertically arranged, the air inlet 10 is arranged at the bottom or the lower part of one side of the box body 12, and the air outlet 11 is arranged at the top or the upper part of one side of the box body 12. That is, the magnetic column 13 can be vertically arranged, and the air inlet 10 and the air outlet 11 can be freely combined according to the positions of the air inlet 10 and the air outlet 11 as described above. The positions of the air inlet 10 and the air outlet 11 can be arranged as needed, i.e. the air flowing into the air inlet 10 can flow out of the air outlet 11 after flowing through all the coils 14 of the box body 12. As shown in Figure 1 the air inlet 10 is arranged at the bottom of the box body 12, and the air outlet 11 is arranged at the top of the box body 12; as shown in Figure 2 the air inlet 10 is arranged at the bottom of the box body 12, and the air outlet 11 is arranged at the top of the box body 12; as shown in Figure 3As shown, the air inlet 10 is arranged at the lower part of the side surface of the cabinet 12, and the air outlet 11 is arranged at the upper part of the side surface of the cabinet 12.
[0038] Preferably, the magnetic column 13 is arranged vertically, and the air inlet 10 and the air outlet 11 are arranged at the upper and lower parts of the front surface of the cabinet 12 respectively. Figure 4 As shown, the air inlet 10 is arranged at the left side of the cabinet 12, and the air outlet 11 is arranged at the right side of the cabinet 12, and the fan is not shown in the figure; of course, the air inlet 10 and the air outlet 11 can also be arranged at the two ends of the front surface of the cabinet 12 respectively, and the air inlet 10 and the air outlet 11 can also be arranged at the two ends of the rear surface of the cabinet 12 respectively. That is, the magnetic column 13 can be arranged transversely, and the air inlet 10 and the air outlet 11 can be arranged in the above-mentioned manner, that is, to ensure that the air entering the air inlet 10 flows out from the air outlet 11 after flowing through the coil 14 of the cabinet 12.
