Of these two grooves, the groove located on the outer peripheral side of the first housing 4 and the second housing 5 is located between the seal material pressing part 9 on the first housing 4 and the groove on the outer peripheral side of the second housing 5. This is a sealing material application section 10.

- the first length 11a is longer than the second length 11b. That is, with respect to the sealing material application portion 10, the bonding area closer to the coolant flow path 2 is larger than that on the outer peripheral side of the bonding surface. This is because internal pressure is applied to the adhesive surface from the refrigerant in the refrigerant flow path 2, so that the first casing 4 expands due to the internal pressure.
- first length 11a the portion with a large bonding area (first length 11a) is arranged close to the refrigerant flow path 2. Furthermore, since the sealant 7 protrudes into the sealant inflow suppressing section 8 when the cases are bonded together, a wide range of bonding surface is ensured in the first length 11a to prevent the sealant 7 from protruding too much. ing.

- the amount of the sealant 7 applied is controlled to a predetermined amount by a coating machine or the like, and the sealant 7, which is spread out in the left and right direction when the casings are bonded to each other, is kept in the sealant inflow suppressing section 8. Since it is adjusted so that the sealing material 7 can be prevented from flowing into the refrigerant flow path 2. Further, the width of the sealing material application section 10 is such that the amount of application of the sealing material 7 can be sufficiently received.

Can have power.
- the sealing material 7 is spread out in the horizontal direction of the adhesive surface. As a result, a part of the sealing material 7 accumulates in the groove of the sealing material inflow suppressing part 8 on the side of the refrigerant flow path 2, while a part of the sealing material 7 accumulates in the sealing material storage part 12 when it is pushed toward the outer peripheral part. becomes accumulated.
- the sealant pressing part 9 of the first casing 4 separates the air drawn into the sealant 7 and pushes it toward both ends of the bonding surface. Since the adhesive is discharged, the adhesion area in the sealant application section 10 can be secured. Furthermore, by making the adhesive strength uniform, the adhesive force of the adhesive surface is stabilized. Further, since the sealing material 7 is applied and pressed using only one groove instead of the double groove structure shown in the prior art, it is possible to improve the reliability of adhesion by preventing air entrainment.

- the sealing material 7 tends to adhere to the side of the case that has a large surface area when the cases are overlapped, which poses a problem in the reliability of the adhesion surface. This problem can be prevented by matching the lengths between the ends of the housing 5 and bonding them together. Further, since the first end 4a and the third end 5a are combined, there is an effect that the sealing material 7 does not flow into the refrigerant flow path 2 even if it is separated from the sealing material inflow suppressing part 8.
- first casing 4 and the second casing 5 are each provided with a sealing material reservoir 12 for storing the sealing material 7 at the outer periphery of the adhesive surface of each casing. This prevents the sealing material 7 from excessively protruding to the outer periphery of the adhesive surface, preventing salt accumulation from occurring in the protruding portion, and suppressing corrosion of the sealing material 7.

As such, both ends of the application section are not perpendicular, but sloped. This allows the sealing material 7 to flow easily when the casings are bonded together. Since the sealing material pressing part 9 is the center of the horizontal spread of the sealing material 7 during assembly, the way the sealing material 7 spreads can be controlled by the position and shape of the pressing part 9.

Further, the sealant pressing section 9 and the sealant applying section 10 can be connected to the first housing 4 or The arrangement can be done independently of which side of the second casing 5 it is attached to.

- a sealing material pressing part 9 that presses the sealing material 7 at a corresponding position, and the refrigerant flow is lower than that of the sealing material application part 10 on the adhesive surface of either the first casing 4 or the second casing 5.
- a sealing material inflow suppressing portion 8 that suppresses the inflow of the sealing material 7 into the refrigerant flow path 2 is provided at a position close to the path 2 .

Abstract
Description
(図1)
図1(a)は筐体に収納するパワーモジュールについての説明図、図1(b)は筐体に取り付けるロアーカバーについての説明図である。半導体装置1は、ケース5に半導体を用いてモータを駆動する電力を出力するパワーモジュール3が挿入されており、パワーモジュールプレート13がケース5に組付けられることによって、挟むようにしてパワーモジュール3を収納・保持している。
図2(a)は図1(b)のA-A断面図、図2(b)は図2(a)の筐体接続部の拡大図である。半導体装置1は、パワーモジュール3を有し、パワーモジュール3をケース5内に収納するためにロアーカバー4をケース5に取り付けている。これにより、パワーモジュール3を冷却する冷媒流路2が形成される。以下の説明以降、ロアーカバー4を第1の筐体4、ケース5を第2の筐体5として説明する。
シール材塗布部10とシール材流入抑制部8は、第1の筐体4と第2の筐体5との接着時に、シール材7の広がり方をコントロールする配置である。シール材塗布部10の位置は、第1の筐体4と第2の筐体5との接着面において、冷媒流路2よりも外周部側に近い位置に配置する。一方で、シール材流入抑制部8の位置は、第1の筐体4と第2の筐体5との接着面において、外周部側よりも冷媒流路2に近い位置に配置する。
図4(a)はシール材塗布部10にシール材7を塗布した図、図4(b)は第1の筐体4と第2の筐体5とが接着する途中の様子を表した図、図4(c)は第1の筐体4と第2の筐体5とが接着した時の様子を表した図である。図4(a)~図4(c)で筐体同士の接続の一連のプロセスを表している。
シール材塗布部10は、シール材7が塗布され第1の筐体4が第2の筐体5に取り付けられる際に、シール材押圧部9がシール材7を押し広げながらエアーを排出が出来るよう、塗布部両端は直角の形状ではなく、斜面の形状が設けられている。これにより、筐体同士の接着時にシール材7を流動しやすいようにする。シール材押圧部9は組み立て時におけるシール材7の左右の広がりの中心となるため、押圧部9の位置や形状によりシール材7の広がり方をコントロールできる。
(図6)
シール材流入抑制部8は第1の筐体4または第2の筐体5のどちらに設けてもよい。また、シール材押圧部9とシール材塗布部10は、接着時にシール材押圧部9がシール材塗布部10に収納されてさえいれば、シール材流入抑制部8が第1の筐体4または第2の筐体5のどちらについているかに依存せずに配置することができる。
(図7)
図7(a)に示すように、押圧部の周囲に溝を有したシール材押圧部9bでも同様の効果を奏することができ、これにより、溝を有さないシール材押圧部9よりも、簡易的な加工でシール材押圧部9を形成できる。また、図7(b)に示すように、シール材塗布部10は、シール材押圧部9に対応した接着面積でなくてもよく、また、シール材押圧部9がシール材塗布部10の中心に来るような配置にしない形状であってもよい。
