The core 32 is provided with a locking part 321 which locks a reactor core 31 not to move in the direction of the open portion 34. Consequently, the radius of the reactor coil 15 can be reduced without interfering the formation of a magnetic path for a magnetic flux generated in the inside direction of the reactor coil 15.

  When the reactor coil of the reactor device is energized, a magnetic flux is generated. In particular, in the case of the cylindrical reactor coil disclosed in Patent Document 1, the magnetic flux concentrates inside the cylindrical shape of the reactor coil, and the magnetic flux density increases. When the coil radius of the reactor coil is reduced in order to reduce the size of such a reactor device, the distances between the reactor coil and the bolt insertion hole and the bolt inserted inside the reactor core are reduced. Therefore, the formation of magnetic flux is hindered inside the cylindrical shape of the reactor coil where the magnetic flux is concentrated. Thereby, the inductance of a reactor apparatus falls and there exists a problem that a reactor apparatus cannot exhibit a desired function. In addition, there is a problem that the reactor core is dropped from the casing due to road surface conditions when the vehicle is traveling, vibration due to the driving engine, or deformation caused by thermal contraction or thermal expansion of the reactor core. Therefore, when the bolt insertion hole and the bolt are lost to secure a space for forming a magnetic path inside the cylindrical reactor coil, it is difficult to fix the reactor core to the casing.

  Therefore, the present invention has been made in view of such a problem, and an object thereof is to provide a reactor device that achieves both a reduction in size of the reactor device and prevention of dropping of the reactor core from the housing.

  In order to solve the above problems, the invention according to claim 1 is a state in which a reactor coil that generates a magnetic flux by energization, a magnetic powder filled in an inner periphery and an outer periphery of the reactor coil, and the magnetic powder are dispersed.

A core is formed on the core, and the core includes a locking portion that locks movement of the reactor core toward the opening, and the core has a front Characterized in that it is formed so as to be located between the end face of the end wall facing the reactor coil and said end wall portion.

  If comprised in this way, a center core is formed so that it may be located between the end surface and end wall part of the reactor coil which oppose an end wall part. Therefore, compared with the configuration in which the core is formed from the inner side of the reactor coil and from the end wall portion to the open portion, the core of the present invention prevents the formation of the magnetic path of the magnetic flux generated in the inner direction of the reactor coil. Absent. Therefore, according to the present invention, the coil radius of the reactor coil can be reduced compared to the configuration in which the core is formed from the inside of the reactor coil and from the end wall portion to the open portion. Can be

  Further, since the core includes a locking portion that locks the movement of the reactor core toward the opening portion, it is possible to prevent the reactor core from falling off the housing.

  Further, since the core is formed from the end wall portion, the heat of the reactor core can be radiated to the reactor case via the core.

For this reason, when the reactor core moves in the direction of the opening portion, the locking portion locks the movement of the reactor core. Therefore, according to the present invention, it is possible to prevent the reactor core from dropping from the housing.

  FIG. 2 shows a plan view of the semiconductor cooler 2 constituting the power conversion device 1.

  The semiconductor cooler 2 constitutes a part of an inverter as the power conversion device 1 that drives the AC motor 12. As shown in FIG. 2, the cooling pipe 3 is arranged so as to sandwich the semiconductor modules 16A and 16B from both sides. And the laminated body which laminated | stacked the cooling pipe 3 and the row | line | column of semiconductor module 16A, 16B alternately is comprised as a whole. Thereby, all the semiconductor modules 16 </ b> A and 16 </ b> B are in a state where both surfaces thereof are sandwiched by the cooling pipe 3. In addition, a plurality of cooling pipes 3 adjacent to each other in the stacking direction are connected to each other by refrigerant pipes (not shown) and refrigerant outlets (not shown) provided at both ends in the longitudinal direction.

And are arranged. Further, the reactor device 30 is disposed at one end of the laminated body that is 180 degrees opposite to the positions where the refrigerant introduction pipe 5 and the refrigerant discharge pipe 6 are arranged. The cooling pipes 3 arranged at both ends of the laminated body are provided with heat radiation surfaces 21 on which semiconductor modules 16A and 16B are arranged in close contact only on one side. The cooling pipes 3 arranged at the ends other than the both ends of the laminated body are provided with heat radiation surfaces 21 on both sides.

  With this configuration, the cooling medium introduced from the refrigerant introduction pipe 5 is distributed to the plurality of cooling pipes 3. The cooling medium is introduced from a refrigerant inlet (not shown) in each cooling pipe 3 and flows in the direction of a refrigerant outlet (not shown) in each cooling pipe 3. At this time, the cooling medium exchanges heat between the semiconductor modules 16 </ b> A and 16 </ b> B and the reactor device 30 arranged in close contact with the heat radiation surface 21 of each cooling pipe 3.

  Next, the specific structure of the reactor apparatus 30 including the reactor coil 15 arrange | positioned at the said power converter device 1 is demonstrated.

  Fig.3 (a) is the top view of the reactor apparatus 30 in Example 1, FIG.3 (b) has shown AA sectional drawing of Fig.3 (a).

  The reactor device 30 includes a reactor coil 15, a reactor core 31, a core 32, and a reactor case 33.

  The reactor case 33 has a rectangular outer shape. The reactor case 33 includes a side wall portion 331 that covers the entire circumference of the side surface of the reactor core 31, and an end wall portion 332 that is formed at the end portion of the side wall portion 331 and covers the end surface of the reactor core 31. Further, the reactor case 33 includes an open portion 34 on the side opposite to the end wall portion 332 by 180 degrees. Reactor case 33 is formed with a concave shape that accommodates reactor coil 15, reactor core 31 and core 32 in the space surrounded by side wall portion 331 and end wall portion 332. The reactor case 33 is made of aluminum having a high thermal conductivity.

  The reactor coil 15 is configured to have a cylindrical shape by spirally winding a flat conductor wire made of a copper wire. Moreover, the coil terminal part 151 of the both ends of the reactor coil 15 is pulled out of the reactor apparatus 30 through the open part 34, and is connected with the exterior. The reactor coil 15 is entirely surrounded by the reactor core 31, and the reactor core 31 is in close contact with the side wall portion 331 and the end wall portion 332 of the reactor case 33. Further, the reactor coil 15 is arranged at a certain distance from the side wall portion 331 and the end wall portion 332 of the reactor case 33 in order to secure a magnetic path in the reactor case 33.

  The reactor core 31 uses a dust core in which a magnetic powder and a resin encapsulated in a state where the magnetic iron powder is dispersed are mixed. The dust core is filled in the inner periphery and the outer periphery of the reactor coil 15, is cured, and is in close contact with the side wall portion 331 and the end wall portion 332 of the reactor case 33. Magnetic powder used in the dust core includes soft magnetic iron, iron / silicon, iron / nickel, iron / cobalt alloy, iron / aluminum, soft ferrite powder, reduced iron powder, atomized iron powder, silicon alloy iron powder, etc. Can be used. As the resin, an epoxy resin excellent in heat resistance, insulation, and adhesion, and a phenol resin, a nylon resin, a polyamide resin, a polyester resin, and the like are used.

  Next, the main part of a present Example is demonstrated.

  As shown in FIG. 3, the reactor device 30 is formed with a core 32 that protrudes from the end wall portion 332 of the reactor case 33 toward the open portion 34. The core 32 includes a locking portion 321 that locks the movement of the reactor core 31 in the direction of the opening portion 34. Specifically, the core 32 in the first embodiment has a cylindrical shape. The center core 32 is formed so as to be integrated with the end wall portion 332 located on the central axis of the reactor coil 15. A locking portion 321 is formed to project from the peripheral edge of the end portion of the intermediate core 32 in the opposite end wall portion direction to the direction orthogonal to the opening portion 34 direction from the end wall portion 332. That is, the locking part 321 is positioned in a state orthogonal to the direction of the opening part 34 from the end wall part 332. Further, when viewed from the axial direction of the reactor coil 15, the locking portion 321 has a circular shape. The distal end of the locking portion 321 is formed so as to be located within the coil inner diameter of the cylindrical reactor coil 15. For this reason, the inner diameter r1 of the reactor coil 15 and the circular diameter r2 of the locking portion 321 have a relationship of r1> r2. The core 32 is formed between the end surface of the reactor coil 15 on the end wall portion 332 side and the end wall portion 332. That is, the core 32 is formed so that the front end of the locking portion 321 on the reactor coil 15 side is positioned closer to the end wall portion 332 than the end surface of the reactor coil 15 on the end wall portion 332 side. The core 32 in the first embodiment is made of aluminum having a high thermal conductivity.

  Next, the manufacturing method of the reactor apparatus 30 in Example 1 is demonstrated using FIG.

  First, as shown in FIG. 4A, a coil positioning table 35 for determining the position of the reactor coil 15 is provided for the reactor case 33 formed so that the core 32 is integrated. The coil positioning table 35 is a dust core formed in a rectangular parallelepiped shape in advance, and the reactor coil 15 is placed on the coil positioning table 35. At this time, the coil terminal portions 151 at both ends of the reactor coil 15 are projected outward from the open portion 34 of the reactor case 33. Next, as shown in FIG. 4 (b), a magnetic powder mixed resin liquid 40 serving as a dust core is injected from the open portion of the reactor case 33. Then, the reactor core 31 is formed including the dust core used as the coil positioning table 35 by solidifying the magnetic powder mixed resin liquid 40 at a predetermined heating temperature for a predetermined time. By this solidification, the reactor core 31 and the side wall portion 331 and the end wall portion 332 of the reactor case 33 are brought into close contact with each other. Further, the inner core 32 is covered with the reactor core 31. Therefore, the locking portion 321 of the center core 32 bites into the reactor core 31 in the direction orthogonal to the direction in which the reactor core 31 moves to drop off from the reactor case 33 (the direction from the end wall portion 332 to the opening portion 34). It becomes a state.

  Next, the effect of Example 1 is demonstrated.

  In the first embodiment, the core 32 is formed so as to be integrated with the end wall portion 332 located on the central axis of the reactor coil 15, and the end surface and the end wall portion 332 of the reactor coil 15 facing the end wall portion 332. It is formed so that it may be located between. Therefore, compared to the configuration in which the core 32 is formed from the inner side of the reactor coil 15 and from the end wall portion 332 to the open portion 34, the core 32 of the first embodiment has a magnetic flux generated in the inner direction of the reactor coil 15. Does not interfere with magnetic path formation. Therefore, since the coil radius of the reactor coil 15 can be reduced as compared with the configuration in which the core 32 is formed from the inner side of the reactor coil 15 and from the end wall portion 332 to the open portion 34, the reactor device 30 can be reduced in size. Can be

  Further, the locking portion 321 of the center core 32 bites into the reactor core 31 with respect to the direction perpendicular to the direction in which the reactor core 31 moves to drop off from the reactor case 33 (from the end wall portion 332 to the opening portion 34). Therefore, the reactor core 31 can be prevented from dropping from the reactor case 33.

  Further, since the core 32 is formed from the end wall portion 332, the heat of the reactor core 31 positioned inside the reactor coil 15 can be radiated to the reactor case 33 through the core 32.

(Example 2)
Next, Example 2 will be described.

  FIG. 5A is a plan view of the reactor device according to the second embodiment, and FIG. 5B is a cross-sectional view taken along line AA in FIG.

  In the second embodiment, as shown in FIGS. 5A and 5B, the reactor case 33 is provided with a lid portion 36 that covers the open portion 34, and the lid portion 36 extends from the lid portion 36 toward the end wall portion 332. The point from which the 2nd center core 37 which protrudes in this way is formed differs from Example 1. FIG. Specifically, the second core 37 is integrated with the lid 36 positioned on the central axis of the reactor coil 15, that is, the lid 36 at a position facing the core 32 formed on the end wall 332. Is formed. The second center core 37 has a truncated cone shape. The bottom surface of the truncated cone shape is formed so as to be integrated with the lid portion 36, and the upper surface of the truncated cone shape is formed so as to face the center core 32. . Further, when viewed from the axial direction of the reactor coil 15, the second core 37 is formed so as to be positioned within the coil inner diameter of the cylindrical reactor coil 15. For this reason, the diameter r3 of the bottom surface of the truncated cone and the diameter r4 of the top surface have a relationship of r1> r3> r4. Further, the circular diameter r2 of the locking portion 32 and the diameter r3 of the bottom surface of the second core 36 have a relationship of r2 = r3. Unlike the core 32, the second core 37 does not include the locking portion 321, and the frustoconical side surface is tapered. The second core 37 is formed so as to be positioned between the end surface of the reactor coil 15 on the lid 36 side and the lid 36. That is, the second core 37 is formed so that the upper surface of the second core 37 is positioned closer to the lid 36 than the end surface of the reactor coil 15 on the lid 36. Further, the second core 37 in the second embodiment is made of aluminum having a high thermal conductivity.

  Two terminal holes 361 are formed in the lid portion 36, and the coil terminal portions 151 at both ends of the reactor coil 15 protrude outside the reactor case 33 through the terminal holes 361.

  The configuration other than the above is the same as that of the first embodiment.

  Next, the effect of Example 2 is demonstrated.

  In the second embodiment, a second core 37 is formed in the direction of the end wall portion 332 from the lid portion 36 that covers the open portion 34 at a position facing the end wall portion 332. Therefore, the heat of the reactor core 31 located inside the reactor coil 15 can be radiated to the lid portion 36 via the second core. Therefore, compared with Example 1, the heat dissipation of the reactor apparatus 30 can be improved.

  In the above embodiment, the second core 37 is formed on the lid 36, but the second core 37 may not be formed on the lid 36.

  In the above embodiment, the locking portion 321 is formed from the peripheral edge of the end portion of the center core 32 in the opposite end wall portion direction, but the end portion on the end wall portion 332 side and the end portion on the opposite end wall portion side You may form between.

  -In the said Example, as shown to Fig.6 (a), (b), it is good also considering the curved surface of the column-shaped center core 32 as an external thread shape, and making it the latching | locking part 321. FIG. Thereby, the latching | locking part 321 is formed in the outer peripheral surface side of the core 32, and protrudes in the direction which cross | intersects the axial direction of the reactor coil 15.

Further, as shown in FIGS. 8A and 8B, the tip of the locking portion 321 formed on the core 32 shown in FIG. 3B may be bent 90 degrees in the direction of the end wall portion 332. .
