Description

【０００１】
【発明の属する技術分野】
本発明は、給気マニホールドに冷却水を通す複数の平行な冷却水通水管と冷却水通水管に貫通される多数のフィンからなる冷却コアを備えた内燃機関の給気冷却装置に関するものである。
【０００２】
【従来の技術】
図３は、従来の内燃機関の給気冷却器２００の一部縦断正面図である。図３に示すように従来の給気冷却器２００は、紙面と直角方向に並列に配置された多数のフィン９２（図３では１枚のみを表示）を複数の冷却水通水管９３で貫通させた冷却コア部を備えている。この給気冷却器２００は、上流側には高温の空気流９０を通すエアダクト９１がボルト８８で接続されており、下流側には給気マニホールド９４がボルト８９で接続されている。さらに給気マニホールド９４はシリンダヘッド９５内の吸気ポートと連通するように接続されている。
【０００３】
図４は、図３とは別の従来の給気冷却器３００（コルゲートタイプ）の縦断正面図である。給気冷却器３００も給気冷却器２００と同様に、上流側にはエアダクト９６がボルト８６で接続されており、下流側には給気マニホールド９７がボルト８７で接続されて冷却された空気がシリンダヘッド９８内の給気通路に流入するようになっている。
【０００４】
図３の給気冷却器２００では冷却水として主に海水が使用され、また、図４の給気冷却器３００では清水（水道水等）が使用され、両者の間には冷却水が海水か清水かの違いによる構造上の相違点はあるものの、基本的にエアダクト（９１，９６）と給気マニホールド（９４，９７）の間に挟持されるような形で設置されている。
【０００５】
そのため、部品点数が多くなり、接続箇所にはボルト（８６〜８９）を設けるためのフランジ部やボルト孔，ねじ穴等を多数設ける必要があり、組立の工数もかかり、コストダウンの図りにくい構造となっている。
【０００６】
【発明が解決しようとする課題】
そこで本発明では、部品点数が少なく、組立が容易な給気冷却装置を提供することを課題としている。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、請求項１に係る発明は、
空気の流れ方向と平行に配置された多数のフィンを複数の冷却水通水管が貫通するように構成された冷却コア部を、給気マニホールドのハウジングの中に内蔵し、
前記複数の冷却水通水管の両端部は、それぞれ、厚肉円板状の支持部材又は有底で円筒状の支持部材の平坦部に対して水密を保ちながら貫通するように構成され、前記２つの支持部材の曲面状の外壁と給気マニホールドのハウジングとの間にそれぞれ水密保持部材を設け、前記支持部材のうちの少なくとも一方が前記ハウジングに対して摺動可能であり、
前記給気マニホールドのハウジング全体を補強するとともに前記冷却コア部を流れる空気を整流する補強整流部を、前記給気マニホールド内に配設してなることを特徴としている。
【０００８】
【発明の実施の形態】
図１は請求項１〜３の発明を実施した給気冷却装置１００の一部縦断正面略図である。また、図２は図１のII−II断面図である。給気冷却装置１００は、エアダクト部１，冷却コア部２及び給気マニホールド部３から構成されている。エアダクト部１と給気マニホールド部３は共通のハウジング１２により一体成形されている。
【０００９】
図１に示すようにエアダクト部１は、内部に整流部１３，１４を備えており、図示しない過給機から供給される高温の圧縮空気流２０を整流し、圧縮空気流２０を下流側へほぼ一様に分配させている。また、整流部１３，１４は、エアダクト部１の補強機能を有しており、給気冷却装置１００の強度を向上させる役割を果たしている。但し、エアダクト部１の強度が十分に確保されており、かつ、空気流が下流側へほぼ一様に分配される場合には、これら整流部１３，１４を要しないのは言うまでもない。
【００１０】
エアダクト部１と給気マニホールド部３の間のハウジング１２には同芯に対向する２つの孔６，７が設けてある。この孔６，７の間に冷却コア部２が挿入配置されている。
【００１１】
冷却コア部２は、多数の平行に配置されたフィン８を複数の冷却水通水管９で貫通させて主要部が構成されており、冷却水通水管９の両端は有底で筒状の支持部材１０，１１に気密を保ち貫通させてある。支持部材１０，１１の代わりに、厚肉状の円板を使用することもできる。
【００１２】
支持部材１０と孔６の間にはＯリング２４，２５（気密保持部材）が設けてある。孔６には給水側蓋４が水密を保ち固着されており、支持部材１０はハウジング１２に対して移動不能に孔６（ハウジング１２）に固定されている。
【００１３】
また、孔７には排水側蓋５が水密を保ち固着されている。排水側蓋５とハウジング１２の間にはＯリング１９が設けてあり、Ｏリング１９の内周部分に支持部材１１の円筒側壁が密着してハウジング１２内と冷却水通路の間の水密及び気密が保たれている。また、排水側蓋５には段２２が形成されており、支持部材１１は冷却水通水管９が熱膨張した際に段２２と支持部材１１の間に形成された隙間２１の間で摺動移動が可能となっている。
【００１４】
図１は、６気筒の内燃機関に適用した場合を示している。給気マニホールド部３は、６つの枝管部２３ａ〜２３ｆが形成されており、各枝管部２３ａ〜２３ｆは図２に示すようにそれぞれシリンダヘッド１７に設けた吸気ポート１８ａ〜１８ｆ（図２にはそのうちの吸気ポート１８ｃのみを表示）と連通している。
【００１５】
また、給気マニホールド部３には下流側整流部１５，２６が設けてある。下流側整流部１５，２６は、冷却コア部２で冷却された低温の空気流を整流し、枝管部２３ａ〜２３ｆから吸気ポート１８ａ〜１８ｆへ円滑に流れるようにすることができる。また整流部１５，２６は、給気マニホールド部３の補強部として機能し、給気冷却装置１００の強度を向上させる役割を果たしている。但し、給気マニホールド部３の強度が十分に確保されており、かつ空気流が下流側へ円滑に流れる場合には、これら整流部１５，２６を要しないのは言うまでもない。
【００１６】
以上のように構成された給気冷却装置１００では、図示しない過給機から高温の圧縮空気流２０が供給され、圧縮空気流２０は上流側整流部１３，１４により三手に分岐して進行し、エアダクト部１の長手方向（図１で見て左右方向）に一様に分散され、冷却コア部２へと流入する。
【００１７】
圧縮空気は冷却コア部２で冷却され、低温の空気流が給気マニホールド部３の枝管部２３ａ〜２３ｆ及びシリンダヘッド１７の吸気ポート１８ａ〜１８ｆを介して各気筒の燃焼室内に供給される。
【００１８】
冷却水通水管９及びフィン８は、低温の冷却水と高温の圧縮空気流の間の熱交換が良好に行われるように、熱伝導率の高い金属（例えば銅）で形成されている。冷却水通水管９は、給水側蓋４から供給される冷却水をハウジング１２内に混入させないように排水側蓋７まで導く。フィン８は薄い略円板形であり、例えば厚さ０．２ｍｍのフィン８が１ｍｍ間隔で配置されて多数の冷却水通水管９に貫通されている。
【００１９】
図１の給気冷却装置１００では、支持部材１１のみが移動可能な構成になっているが、支持部材１０も支持部材１１と同様に構成して移動可能にしても差し支えない。ただし、その際には、支持部材１０の移動範囲は孔６と給水側蓋４の内周面（孔６と同径の部分）に限定されるようにする。図１の空気冷却器では、冷却水は一方の給水側蓋６から入り、冷却水通水管９を経て他方の排水側蓋５へと流れるが、一方の側蓋に給排水口を設け、他方の側蓋で折り返す（Ｕターン）方式を採用することもできる。
【００２０】
給気冷却装置１００を鋳物で一体成形すると、図１，図２に示すように、ハウジング１２にリブ１６を一体に設け、冷却コア部２を内蔵する部分のハウジング１２を容易に補強することができる。
【００２１】
比較的低出力の内燃機関においては、圧縮空気流２０の温度が比較的低温となり、冷却水通水管９が昇温して膨張する度合が小さくなるので、支持部材１０，１１の両方を摺動移動不能にハウジング１２に拘束（固着）するようにしてもよい。また、気筒数の少ない内燃機関においても、冷却コア部の全長が短く膨張量が小さいので、支持部材１０，１１の両方を摺動移動不能にハウジング１２に拘束（固着）するようにしてもよい。
【００２２】
【発明の効果】
請求項１の発明では、給気マニホールド部３を形成するハウジング１２に冷却コア部２を内蔵させるようにしたので、従来のような給気冷却器２００（図３）と給気マニホールド９４とを接続するために必要な部材が不要であり、部品点数の削減と組立の容易化を図ることができる。
【００２３】
請求項２の発明では、冷却水通水管９の両端に設けた支持部材１０、１１のうちの少なくとも一方がハウジング１２に対して摺動可能にしたので、冷却水通水管９が昇温して膨張しても、支持部材１０，１１の少なくともどちらか一方をハウジング１２に対して摺動させることにより冷却コア部２及びハウジング１２にかかる負担を軽減して破損を回避することができ、安全性を確保することができる。
【００２４】
請求項３の発明において、エアダクト部１（給気マニホールド）内に整流部１３，１４を設けると、過給機から供給される高温の圧縮空気流２０を整流し、圧縮空気流２０を下流側へほぼ一様に分配させることができる。また、給気マニホールド３内に下流側整流部１５，２６を設けると、冷却された空気流は円滑に枝管部２３ａ〜２３ｆからシリンダヘッド１７の吸気ポート１８ａ〜１８ｆ内へ流入させることができる。さらに、整流部１３，１４は一体成形された給気冷却装置１００のエアダクト部１の補強部材として機能させることができ、下流側整流部１５，２６は、一体成形された給気冷却装置１００の給気マニホールド部３の補強部材として機能させることができる。

In the supply air cooler 200 in FIG. 3, seawater is mainly used as cooling water, and in the supply air cooler 300 in FIG. 4, fresh water (tap water or the like) is used. Although there is a difference in structure depending on whether it is fresh water, it is basically installed so as to be sandwiched between the air duct (91, 96) and the air supply manifold (94, 97).
[0005]
For this reason, the number of parts is increased, and it is necessary to provide a large number of flanges, bolt holes, screw holes, and the like for providing bolts (86 to 89) at connection points. It has become.
[0006]

A reinforcing rectifying unit that reinforces the entire housing of the air supply manifold and rectifies the air flowing through the cooling core portion is provided in the air supply manifold.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a partially longitudinal schematic front view of an air supply and cooling device 100 embodying the inventions of claims 1 to 3. 2 is a cross-sectional view taken along the line II-II in FIG. The air supply and cooling device 100 includes an air duct portion 1, a cooling core portion 2, and an air supply manifold portion 3. The air duct portion 1 and the air supply manifold portion 3 are integrally formed by a common housing 12.
[0009]
As shown in FIG. 1, the air duct unit 1 includes rectifying units 13 and 14 inside, rectifies a high-temperature compressed air flow 20 supplied from a supercharger (not shown), and moves the compressed air flow 20 downstream. Almost uniformly distributed. Further, the rectifying units 13 and 14 have a function of reinforcing the air duct unit 1 and play a role of improving the strength of the air supply and cooling device 100. However, it is needless to say that the rectifying sections 13 and 14 are not required when the strength of the air duct section 1 is sufficiently secured and the air flow is distributed substantially uniformly downstream.
[0010]
The housing 12 between the air duct portion 1 and the air supply manifold portion 3 is provided with two holes 6 and 7 facing concentrically. The cooling core portion 2 is inserted between the holes 6 and 7.
[0011]
The cooling core portion 2 has a main portion formed by passing a plurality of fins 8 arranged in parallel through a plurality of cooling water flow pipes 9, and both ends of the cooling water flow pipes 9 are bottomed and cylindrically supported. The members 10 and 11 are kept airtight and penetrated. Instead of the support members 10 and 11, a thick disk can be used.
[0012]
O-rings 24 and 25 (airtight holding members) are provided between the support member 10 and the hole 6. The water supply side lid 4 is fixed to the hole 6 while maintaining watertightness, and the support member 10 is fixed to the hole 6 (housing 12) so as not to move with respect to the housing 12.
[0013]
Further, the drainage side lid 5 is fixed to the hole 7 while keeping watertight. An O-ring 19 is provided between the drainage-side lid 5 and the housing 12, and the cylindrical side wall of the support member 11 is in close contact with the inner peripheral portion of the O-ring 19 so that watertightness and airtightness between the housing 12 and the cooling water passage are provided. Is maintained. Further, a step 22 is formed on the drainage side lid 5, and the support member 11 slides between a gap 21 formed between the step 22 and the support member 11 when the cooling water flow pipe 9 is thermally expanded. It is possible to move.
[0014]
FIG. 1 shows a case where the present invention is applied to a 6-cylinder internal combustion engine. The supply manifold section 3 is formed with six branch pipe sections 23a to 23f, and the branch pipe sections 23a to 23f are respectively provided with intake ports 18a to 18f (FIG. 2) provided in the cylinder head 17, as shown in FIG. (Only the intake port 18c is shown).
[0015]
The air supply manifold section 3 is provided with downstream rectification sections 15 and 26. The downstream side rectification units 15 and 26 can rectify the low-temperature air flow cooled by the cooling core unit 2 and smoothly flow from the branch pipe portions 23a to 23f to the intake ports 18a to 18f. The rectifying units 15 and 26 function as reinforcing portions of the air supply manifold unit 3 and play a role of improving the strength of the air supply cooling device 100. However, it is needless to say that the rectifying sections 15 and 26 are not required when the strength of the air supply manifold section 3 is sufficiently secured and the airflow smoothly flows downstream.
[0016]
In the supply air cooling apparatus 100 configured as described above, a high-temperature compressed air flow 20 is supplied from a supercharger (not shown), and the compressed air flow 20 is branched into three hands by the upstream rectification units 13 and 14 and proceeds. Then, the air is uniformly dispersed in the longitudinal direction of the air duct portion 1 (left and right direction as viewed in FIG. 1) and flows into the cooling core portion 2.
[0017]
The compressed air is cooled by the cooling core portion 2, and a low-temperature air flow is supplied into the combustion chamber of each cylinder via the branch pipe portions 23 a to 23 f of the air supply manifold portion 3 and the intake ports 18 a to 18 f of the cylinder head 17. .
[0018]
The cooling water flow pipes 9 and the fins 8 are formed of a metal having a high thermal conductivity (for example, copper) so that heat exchange between the low-temperature cooling water and the high-temperature compressed air flow can be performed satisfactorily. The cooling water flow pipe 9 guides the cooling water supplied from the water supply side lid 4 to the drain side lid 7 so as not to be mixed into the housing 12. The fins 8 are thin and substantially disk-shaped. For example, fins 8 having a thickness of 0.2 mm are arranged at intervals of 1 mm and penetrated through a large number of cooling water flow pipes 9.
[0019]
1, only the support member 11 is movable. However, the support member 10 may be configured and moved in the same manner as the support member 11. In this case, however, the movement range of the support member 10 is limited to the hole 6 and the inner peripheral surface of the water supply side lid 4 (portion having the same diameter as the hole 6). In the air cooler of FIG. 1, the cooling water enters from one water supply side lid 6 and flows to the other drainage side lid 5 through the cooling water flow pipe 9, but one side lid is provided with a water supply / drainage port, It is also possible to adopt a method of folding back (U-turn) with a side cover.
[0020]
When the air supply and cooling device 100 is integrally formed of a casting, as shown in FIGS. 1 and 2, the ribs 16 are integrally provided in the housing 12, and the housing 12 in the portion containing the cooling core portion 2 can be easily reinforced. it can.
[0021]
In an internal combustion engine with a relatively low output, the temperature of the compressed air flow 20 is relatively low, and the degree of expansion of the cooling water water pipe 9 is reduced, so that both the support members 10 and 11 are slid. You may make it restrain (fix) to the housing 12 so that it cannot move. Further, even in an internal combustion engine having a small number of cylinders, since the entire length of the cooling core portion is short and the expansion amount is small, both the support members 10 and 11 may be restrained (fixed) to the housing 12 so that they cannot slide. .
[0022]
【The invention's effect】
According to the first aspect of the present invention, since the cooling core portion 2 is built in the housing 12 forming the air supply manifold portion 3, the conventional air supply cooler 200 (FIG. 3) and the air supply manifold 94 are provided. Members required for connection are unnecessary, and the number of parts can be reduced and assembly can be facilitated.
[0023]
In the invention of claim 2, since at least one of the support members 10, 11 provided at both ends of the cooling water water pipe 9 is slidable with respect to the housing 12, the cooling water water pipe 9 is heated. Even if it expands, by sliding at least one of the support members 10 and 11 with respect to the housing 12, it is possible to reduce the burden on the cooling core portion 2 and the housing 12 and to avoid breakage. Can be secured.
[0024]
In the invention of claim 3, when the rectifying sections 13 and 14 are provided in the air duct section 1 (supply manifold), the hot compressed air flow 20 supplied from the supercharger is rectified, and the compressed air stream 20 is placed downstream. Can be distributed almost uniformly. Further, if the downstream side rectification units 15 and 26 are provided in the air supply manifold 3, the cooled air flow can smoothly flow into the intake ports 18a to 18f of the cylinder head 17 from the branch pipe portions 23a to 23f. . Furthermore, the rectifying units 13 and 14 can function as a reinforcing member of the air duct unit 1 of the integrally formed air supply cooling device 100, and the downstream rectifying units 15 and 26 are configured as the integrally formed air supply cooling device 100. It can function as a reinforcing member for the air supply manifold section 3.
