以下、本発明の実施の形態を図面に基づき説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の第１の実施形態に係わる回転電機構造の斜視図で、図２は図１とは反対の紙面裏側から見た斜視図である。回転電機構造のハウジング１は、大略円筒形状のモータ部３と、モータ部３の円筒形状部分の図１中で上部側の側部に一体的に設けられて大略直方体形状のインバータ部５とを備えている。   FIG. 1 is a perspective view of a rotating electrical machine structure according to the first embodiment of the present invention, and FIG. 2 is a perspective view as viewed from the back side of the paper, opposite to FIG. A housing 1 having a rotating electrical machine structure includes a motor portion 3 having a substantially cylindrical shape, and an inverter portion 5 having a substantially rectangular parallelepiped shape which is integrally provided on the upper side of the cylindrical portion of the motor portion 3 in FIG. I have.

モータ部３内には、回転電機としてのモータ７が収容され、インバータ部５内には、電力変換装置としてのインバータ９が収容される。したがって、モータ部３は回転電機収容部を構成し、インバータ部５は電力変換装置収容部を構成する。モータ部３とインバータ部５との間のハウジング１内には、図示しない隔壁が設けられ、当該隔壁にモータ７とインバータ９とを電気的に接続する配線の通し孔を設けている。なお、図２では、モータ７やインバータ９は図示省略している。   A motor 7 as a rotating electrical machine is accommodated in the motor unit 3, and an inverter 9 as a power converter is accommodated in the inverter unit 5. Therefore, the motor part 3 comprises a rotary electric machine accommodating part, and the inverter part 5 comprises a power converter device accommodating part. A partition (not shown) is provided in the housing 1 between the motor unit 3 and the inverter unit 5, and a through hole for wiring for electrically connecting the motor 7 and the inverter 9 is provided in the partition. In FIG. 2, the motor 7 and the inverter 9 are not shown.

インバータ９は、電子部品として、平滑コンデンサ、パワー半導体素子を備えるパワーモジュール、ドライバ基板などを備え、取付部材としてのトレー１１のモータ部３側に対応する下面に取り付けられる。トレー１１は、長方形の板状部材で構成され、材質としては、金属、樹脂、セラミックなどが挙げられる。トレー１１に、インバータ部品である電子部品を複数搭載することでインバータモジュールを構成する。   The inverter 9 includes, as electronic components, a smoothing capacitor, a power module including a power semiconductor element, a driver board, and the like, and is attached to a lower surface corresponding to the motor unit 3 side of the tray 11 as an attachment member. The tray 11 is formed of a rectangular plate-like member, and examples of the material include metal, resin, and ceramic. An inverter module is configured by mounting a plurality of electronic components, which are inverter components, on the tray 11.

インバータ部５は、図３に示すように、モータ部３と反対側の上部が長方形状に開口しており、この開口部に対し、トレー１１が覆うようにして図示しないボルトなどを使用して取り付けられる。その際、ボルトの内側のトレー１１の周縁とインバータ部５の周縁との間の接合部に、シール部材１３を設ける。   As shown in FIG. 3, the inverter unit 5 has a rectangular opening on the upper side opposite to the motor unit 3, and a bolt or the like (not shown) is used so that the tray 11 covers the opening. It is attached. At that time, the seal member 13 is provided at the joint between the periphery of the tray 11 inside the bolt and the periphery of the inverter unit 5.

トレー１１の上面、すなわちインバータ９が取り付けられる面と反対側には、水路形成部材１５を接合固定している。水路形成部材１５は、トレー１１に対向する側が開口し、開口側をトレー１１の表面に接合固定することで、トレー１１との間にトレー冷却水通路１７が形成される。トレー冷却水通路１７は、冷却媒体が流れる第２冷却媒体通路を構成する。   A water channel forming member 15 is bonded and fixed to the upper surface of the tray 11, that is, the side opposite to the surface on which the inverter 9 is attached. The water channel forming member 15 opens on the side facing the tray 11, and the tray cooling water passage 17 is formed between the water channel forming member 15 and the tray 11 by bonding and fixing the opening side to the surface of the tray 11. The tray cooling water passage 17 constitutes a second cooling medium passage through which the cooling medium flows.

水路形成部材１５は、長方形状のトレー１１における短辺部に沿って平行に形成される第１主通路形成部１５ａ、第２主通路形成部１５ｂ、第３主通路形成部１５ｃを備える。第１主通路形成部１５ａと第２主通路形成部１５ｂとは、それぞれの一方側の端部同士が第１連絡通路形成部１５ｄで接続される。第２主通路形成部１５ｂと第３主通路形成部１５ｃとは、第１連絡通路形成部１５ｄと反対側の端部同士が第２連絡通路形成部１５ｅで接続される。   The water passage forming member 15 includes a first main passage forming portion 15a, a second main passage forming portion 15b, and a third main passage forming portion 15c that are formed in parallel along the short side portion of the rectangular tray 11. The first main passage forming portion 15a and the second main passage forming portion 15b are connected to each other at one end by a first communication passage forming portion 15d. The second main passage forming portion 15b and the third main passage forming portion 15c are connected to each other at the ends opposite to the first connecting passage forming portion 15d by the second connecting passage forming portion 15e.

したがって、水路形成部材１５は蛇行状に形成される。水路形成部材１５の形状に対応してトレー冷却水通路１７も蛇行状となる。   Therefore, the water channel forming member 15 is formed in a meandering shape. Corresponding to the shape of the water channel forming member 15, the tray cooling water passage 17 also has a meandering shape.

第１主通路形成部１５ａの第１連絡通路形成部１５ｄと反対側の端部は、インバータ部５の外側に突出する出口通路突出部１５ａ１を備える。出口通路突出部１５ａ１に対応してトレー１１にも、図４に示すようにトレー出口突出部１１ａが形成される。トレー出口突出部１１ａの出口通路突出部１５ａ１と反対側の下面には、直管状の出口連結管１９が接合される。出口連結管１９とトレー１１とは、両者が金属の場合には溶接やろう付けにより接合する。出口連結管１９とトレー１１とを樹脂で一体化してもよい。   The end of the first main passage forming portion 15 a opposite to the first communication passage forming portion 15 d includes an outlet passage protruding portion 15 a 1 that protrudes outside the inverter portion 5. As shown in FIG. 4, a tray outlet projection 11a is also formed on the tray 11 corresponding to the outlet passage projection 15a1. A straight tubular outlet connecting pipe 19 is joined to the lower surface of the tray outlet protruding portion 11a opposite to the outlet passage protruding portion 15a1. The outlet connecting pipe 19 and the tray 11 are joined by welding or brazing when both are metal. The outlet connecting pipe 19 and the tray 11 may be integrated with resin.

出口連結管１９に対応してインバータ部５の外側の壁部には、インバータ部５の開口側の端部からモータ部３にわたってボス部２１が形成されている。ボス部２１内には、図３に示すように第３冷却媒体通路としてのボス部冷却水通路２１ａが形成される。ボス部冷却水通路２１ａ内に出口連結管１９が挿入されて、トレー冷却水通路１７とボス部冷却水通路２１ａとが連通接続される。出口連結管１９の外面とボス部２１の内面との間には、Ｏリングなどのシール材を設けて水密性を確保する。   A boss portion 21 is formed on the outer wall portion of the inverter portion 5 so as to correspond to the outlet connecting pipe 19 from the opening-side end portion of the inverter portion 5 to the motor portion 3. In the boss portion 21, a boss portion cooling water passage 21a as a third cooling medium passage is formed as shown in FIG. The outlet connecting pipe 19 is inserted into the boss portion cooling water passage 21a, and the tray cooling water passage 17 and the boss portion cooling water passage 21a are connected in communication. A sealing material such as an O-ring is provided between the outer surface of the outlet connecting pipe 19 and the inner surface of the boss portion 21 to ensure water tightness.

モータ部３の壁部内には、第１冷却媒体通路としてのハウジング冷却水通路２３を設けている。ハウジング冷却水通路２３と、ボス部冷却水通路２１ａのトレー冷却水通路１７と反対側の下端とは互いに連通している。したがって、第３冷却媒体通路であるボス部冷却水通路２１ａは、第１冷却媒体通路であるハウジング冷却水通路２３と、第２冷却媒体通路であるトレー冷却水通路１７とを接続している。   A housing cooling water passage 23 as a first cooling medium passage is provided in the wall portion of the motor portion 3. The housing cooling water passage 23 and the lower end of the boss portion cooling water passage 21a opposite to the tray cooling water passage 17 communicate with each other. Therefore, the boss part cooling water passage 21a that is the third cooling medium passage connects the housing cooling water passage 23 that is the first cooling medium passage and the tray cooling water passage 17 that is the second cooling medium passage.

ハウジング冷却水通路２３は、円筒形状のモータ部３の壁部内を、壁部のほぼ全域にわたって形成されている。ハウジング冷却水通路２３のボス部冷却水通路２１ａと反対側の端部は、図示していないが、モータ部３の外部に開口して冷却媒体である冷却水の出口部となる。   The housing cooling water passage 23 is formed in the wall portion of the cylindrical motor portion 3 over almost the entire wall portion. Although not shown, the end of the housing cooling water passage 23 opposite to the boss cooling water passage 21a opens to the outside of the motor unit 3 and serves as an outlet for cooling water as a cooling medium.

水路形成部材１５における第３主通路形成部１５ｃの第２連絡通路形成部１５ｅと反対側の端部は、インバータ部５の外側に突出する入口通路突出部１５ｃ１を備える。入口通路突出部１５ｃ１に対応してトレー１１にも、図４に示すようにトレー入口突出部１１ｂが形成される。トレー入口突出部１１ｂの入口通路突出部１５ｃ１と反対側の下面には、Ｌ字管状の入口連結管２５が接合される。入口連結管２５とトレー１１とは、両者が金属の場合には溶接やろう付けにより接合する。入口連結管２５とトレー１１とを樹脂で一体化してもよい。   The end of the water channel forming member 15 opposite to the second communication passage forming portion 15 e of the third main passage forming portion 15 c includes an inlet passage protruding portion 15 c 1 that protrudes outside the inverter portion 5. As shown in FIG. 4, a tray inlet protruding portion 11b is formed on the tray 11 corresponding to the inlet passage protruding portion 15c1. An L-shaped inlet connection pipe 25 is joined to the lower surface of the tray inlet protrusion 11b opposite to the inlet passage protrusion 15c1. The inlet connecting pipe 25 and the tray 11 are joined by welding or brazing when both are metal. The inlet connecting pipe 25 and the tray 11 may be integrated with resin.

入口連結管２５は、外部の図示しない冷却水ポンプに接続される。すなわち、冷却水ポンプから送られる冷却水が、入口連結管２５を経てトレー冷却水通路１７に流入する。   The inlet connection pipe 25 is connected to an external cooling water pump (not shown). That is, the cooling water sent from the cooling water pump flows into the tray cooling water passage 17 through the inlet connecting pipe 25.

トレー冷却水通路１７では、流入した冷却水が、第３主通路形成部１５ｃ、第２連絡通路形成部１５ｅ、第２主通路形成部１５ｂ、第１連絡通路形成部１５ｄ、第１主通路形成部１５ａの順に流れ、その後ボス部冷却水通路２１ａに流入する。トレー冷却水通路１７を流れる冷却水によって、インバータ９の各種電子部品が冷却される。   In the tray cooling water passage 17, the inflowing cooling water forms the third main passage forming portion 15c, the second connecting passage forming portion 15e, the second main passage forming portion 15b, the first connecting passage forming portion 15d, and the first main passage forming. It flows in the order of the portion 15a and then flows into the boss portion cooling water passage 21a. Various electronic components of the inverter 9 are cooled by the cooling water flowing through the tray cooling water passage 17.

ボス部冷却水通路２１ａ内の冷却水はハウジング冷却水通路２３に流入し、ハウジング冷却水通路２３を流れる過程でモータ７を冷却する。モータ７を冷却した冷却水は、ハウジング冷却水通路２３のモータ部３の外部に開口している出口部から外部に排出される。外部に排出された冷却水は、ラジエータなどの熱交換器で冷却された後、冷却水ポンプに戻される。   The cooling water in the boss portion cooling water passage 21 a flows into the housing cooling water passage 23 and cools the motor 7 in the process of flowing through the housing cooling water passage 23. The cooling water that has cooled the motor 7 is discharged to the outside through an outlet portion of the housing cooling water passage 23 that opens to the outside of the motor portion 3. The cooling water discharged to the outside is cooled by a heat exchanger such as a radiator and then returned to the cooling water pump.

図５は、トレー１１と、ハウジング１のインバータ部５との接合面に対応する部分の模式的な平面図である。トレー１１とインバータ部５との間に設けたシール部材１３は、インバータ９が位置する斜線で示す領域Ａを囲むように、当該領域Ａの外側に設置している。さらに、シール部材１３の外側、すなわちシール部材１３を間にして領域Ａと反対側に、出口連結管１９及び入口連結管２５が位置している。   FIG. 5 is a schematic plan view of a portion corresponding to the joint surface between the tray 11 and the inverter unit 5 of the housing 1. The seal member 13 provided between the tray 11 and the inverter unit 5 is installed outside the region A so as to surround the region A indicated by the oblique line where the inverter 9 is located. Further, the outlet connecting pipe 19 and the inlet connecting pipe 25 are located outside the seal member 13, that is, on the side opposite to the region A with the seal member 13 therebetween.

このように、シール部材１３は、トレー１１におけるインバータ９が位置する領域Ａと、出口連結管１９及び入口連結管２５との間に設けられている。このため、出口連結管１９周辺の配管接続部や入口連結管２５周辺の配管接続部から、冷却水が例え漏れたとしても、ハウジング１内の電子部品などが収容されている領域への冷却水の流入を抑えることができ、インバータ９やモータ７を冷却水から保護することができる。   Thus, the seal member 13 is provided between the region A in the tray 11 where the inverter 9 is located and the outlet connecting pipe 19 and the inlet connecting pipe 25. For this reason, even if the cooling water leaks from the pipe connection part around the outlet connection pipe 19 and the pipe connection part around the inlet connection pipe 25, the cooling water to the area in which the electronic components and the like in the housing 1 are accommodated. And the inverter 9 and the motor 7 can be protected from the cooling water.

本実施形態は、出口連結管１９及びボス部冷却水通路２１ａは、トレー１１におけるインバータ９が位置する領域Ａの外側に設けられている。このため、出口連結管１９及びボス部冷却水通路２１ａを、ハウジング１の外側に設けるという簡素な構造で、冷却水のハウジング１内への流入を抑制できる。   In the present embodiment, the outlet connecting pipe 19 and the boss portion cooling water passage 21 a are provided outside the region A in the tray 11 where the inverter 9 is located. For this reason, inflow of the cooling water into the housing 1 can be suppressed with a simple structure in which the outlet connecting pipe 19 and the boss portion cooling water passage 21 a are provided outside the housing 1.

図６は、本発明の第２の実施形態を示す、図３に対応する斜視図である。第２の実施形態は、第１の実施形態の図１、図３に示すボス部２１に代えて、ハウジング１におけるインバータ部５Ａの内部に内部ボス部２１Ａを設けている。内部ボス部２１Ａに対応する位置のトレーの下面には、図４の出口連結管１９に代わる出口連結管１９Ａ（図７参照）を設けている。   FIG. 6 is a perspective view corresponding to FIG. 3, showing a second embodiment of the present invention. In the second embodiment, instead of the boss portion 21 shown in FIGS. 1 and 3 of the first embodiment, an internal boss portion 21 </ b> A is provided inside the inverter portion 5 </ b> A in the housing 1. On the lower surface of the tray at a position corresponding to the internal boss portion 21A, an outlet connecting pipe 19A (see FIG. 7) is provided in place of the outlet connecting pipe 19 in FIG.

内部ボス部２１Ａの内部には、モータ部３Ａのハウジング冷却水通路２３Ａに下端が連通する連通管２７を設けている。連通管２７は、内部に第３冷却媒体通路としての連通管冷却水通路２７ａを備える。連通管２７と内部ボス部２１Ａとの間には、環状の隙間２９が形成される。   A communication pipe 27 having a lower end communicating with the housing cooling water passage 23A of the motor portion 3A is provided inside the internal boss portion 21A. The communication pipe 27 includes a communication pipe cooling water passage 27a as a third cooling medium passage. An annular gap 29 is formed between the communication pipe 27 and the internal boss portion 21A.

隙間２９に図４の出口連結管１９に代わる出口連結管１９Ａを挿入して接続する。このとき、内部ボス部２１Ａの端面２１Ａａとトレーとの間に、シール部材としての内側シール部材３１を設ける。   An outlet connecting pipe 19A instead of the outlet connecting pipe 19 shown in FIG. At this time, an inner seal member 31 as a seal member is provided between the end surface 21Aa of the internal boss portion 21A and the tray.

図７は、第２の実施形態による図５に対応する模式的な平面図である。図７のトレー１１におけるインバータ９が位置する領域Ａは、シール部材１３と内側シール部材３１との間に位置する。内側シール部材３１は、インバータ９が位置する領域Ａと出口連結管１９Ａとの間に設けられている。すなわち、出口連結管１９Ａ及び連通管冷却水通路２７ａは、インバータ９が位置する領域Ａに周囲を囲まれた位置に設けられている。さらに、図７のシール部材１３は、インバータ９が位置する領域Ａと入口連結管２５との間に設けられている。   FIG. 7 is a schematic plan view corresponding to FIG. 5 according to the second embodiment. A region A in which the inverter 9 is located in the tray 11 of FIG. 7 is located between the seal member 13 and the inner seal member 31. The inner seal member 31 is provided between the region A where the inverter 9 is located and the outlet connecting pipe 19A. That is, the outlet connection pipe 19A and the communication pipe cooling water passage 27a are provided at a position surrounded by a region A where the inverter 9 is located. Further, the seal member 13 of FIG. 7 is provided between the region A where the inverter 9 is located and the inlet connection pipe 25.

このように、内側シール部材３１は、トレー１１におけるインバータ９が位置する領域Ａと、出口連結管１９Ａとの間に設けられている。このため、出口連結管１９Ａと連通管２７との接続部周辺から、冷却水が例え漏れたとしても、内側シール部材３１によってハウジング１内の電子部品などが収容されている領域への冷却水の流入を抑えることができる。よって、インバータ９やモータ７を冷却水から保護することができる。   Thus, the inner seal member 31 is provided between the region A in the tray 11 where the inverter 9 is located and the outlet connecting pipe 19A. For this reason, even if the cooling water leaks from the periphery of the connection portion between the outlet connecting pipe 19A and the communication pipe 27, the cooling water is supplied to the area in which the electronic components and the like in the housing 1 are accommodated by the inner seal member 31. Inflow can be suppressed. Therefore, the inverter 9 and the motor 7 can be protected from cooling water.

さらに、シール部材１３は、トレー１１におけるインバータ９が位置する領域Ａと、入口連結管２５との間に設けられている。このため、入口連結管２５と外部の配管との接続部周辺から、冷却水が例え漏れたとしても、シール部材１３によってハウジング１内の電子部品などが収容されている領域への冷却水の流入を抑えることができる。   Further, the seal member 13 is provided between the region A in the tray 11 where the inverter 9 is located and the inlet connection pipe 25. For this reason, even if the cooling water leaks from the periphery of the connection portion between the inlet connecting pipe 25 and the external piping, the cooling water flows into the region in which the electronic components in the housing 1 are accommodated by the seal member 13. Can be suppressed.

インバータ部品をトレー１１によりモジュール化してインバータモジュールとした利点は、以下のとおりである。
（１）インバータモジュール内の電子部品を含むインバータ部品の変更、交換が容易となる。このとき、ハウジング１の形状などの変更は不要であり、部品変更、交換のみの小変更で済み。コスト低下に寄与できる。
（２）回転電機構造におけるインバータに対するメンテナンス時に、ユニット単位（インバータモジュール）での交換が可能となり、メンテナンス作業が容易となる。
（３）インバータモジュールを単体のインバータとして利用することができる。この場合、一種類のインバータモジュールを複数の機器に適用することもでき、利便性が向上する。 Advantages obtained by modularizing the inverter parts with the tray 11 to form an inverter module are as follows.
(1) It is easy to change and replace inverter components including electronic components in the inverter module. At this time, it is not necessary to change the shape of the housing 1, and only a small change of replacement or replacement is required. It can contribute to cost reduction.
(2) During maintenance on the inverter in the rotating electrical machine structure, replacement in units (inverter modules) is possible, and maintenance work is facilitated.
(3) The inverter module can be used as a single inverter. In this case, one type of inverter module can be applied to a plurality of devices, and convenience is improved.
