Description
本発明は、水冷式チャージエアクーラ等に用いられる積層熱交換器に関する。

JP7-112775U discloses a stacked heat exchanger in which a plurality of tube sheets formed by folding a single plate are stacked, and a tank is provided at the end opposite to the folded side of the tube sheet.
上記積層熱交換器においては、振動に対する耐久性を確保できるように、複数のチューブシートの折り返し部を一枚のサイドプレートと接合して連結することで、コアの剛性を高める場合がある。
In the laminated heat exchanger, the rigidity of the core may be increased by joining and connecting the folded portions of a plurality of tube sheets with one side plate so as to ensure durability against vibration.
しかしながら、上記のように一枚のサイドプレートに複数のチューブシートを接合して連結すると、チューブシートの両端がタンクとサイドプレートの接合部とで拘束された状態になるので、高温の媒体が流通してチューブシートが熱膨張した場合の歪の逃げ場が無く、積層したチューブシートの接合部や、媒体の流路周辺に応力が集中するという問題があった。
However, when a plurality of tube sheets are joined and connected to a single side plate as described above, both ends of the tube sheet are constrained by the joint between the tank and the side plate, so that a high-temperature medium flows. As a result, there is no strain escape when the tube sheet is thermally expanded, and there is a problem that stress is concentrated around the joined portion of the laminated tube sheets and around the flow path of the medium.
本発明は、このような技術的課題に鑑みてなされたもので、コアの剛性を確保しつつ熱膨張による応力集中を緩和できる積層熱交換器を提供することを目的とする。

FIG. 2 is a perspective view showing the sheet member. FIG. 3 is a cross-sectional view taken along the line III-III in FIG.
シート部材１４は、プレート１４ａをプレス成形し、上述したように第１シート８と第２シート９と連結部１３とを形成したものである。
The sheet member 14 is obtained by press-molding the plate 14a and forming the first sheet 8, the second sheet 9, and the connecting portion 13 as described above.
プレート１４ａには、両端にそれぞれ２つのバーリング１５が設けられる。そして、第１シート８部に設けられた２つのバーリング１５を繋ぐように、プレート１４ａを正面から見てＵ型の、チューブシート６内に冷却水を循環させる流路を形成するための溝８１が凹設される。第２シート９部についても同様に、２つのバーリング１５を繋ぐようにＵ型の溝９１が凹設される。
The plate 14a is provided with two burrings 15 at both ends. And the groove | channel 81 for forming the flow path which circulates a cooling water in the U-shaped tube sheet 6 seeing the plate 14a from the front so that the two burring 15 provided in the 1st sheet | seat 8 part may be connected. Is recessed. Similarly, a U-shaped groove 91 is also provided in the second sheet 9 so as to connect the two burrings 15.
プレート１４ａを連結部１３で曲折し、両端のバーリング１５のフランジを突き合わせて接合することで、第１シート８と第２シート９とが、突き合わせたフランジの高さの隙間を持って平行に対向したシート部材１４が形成される。
The plate 14a is bent at the connecting portion 13 and the flanges of the burrings 15 at both ends are butted and joined so that the first sheet 8 and the second sheet 9 face each other in parallel with a gap at the height of the butted flanges. The sheet member 14 thus formed is formed.
各部品の接合は、各部品が接触する部分にあらかじめロウ材を被覆し、組み立てた状態で高温の炉内で一体にロウ付け固定して行われる。
接合 Joining of each part is performed by previously brazing a part where each part comes into contact with a brazing material and brazing and fixing in a high temperature furnace in an assembled state.
チューブシート６は、隣接して積層される一方のシート部材の第１シート８に設けられたリブ８２およびプレート基面８３と、他方のシート部材の第２シート９に設けられたリブ９２およびプレート基面９３とを接合して形成され、対向する溝８１と溝９１とによりチューブシート６内に冷却水を循環させる流路１０が形成される。
The tube sheet 6 includes a rib 82 and a plate base surface 83 provided on the first sheet 8 of one sheet member stacked adjacent to each other, and a rib 92 and a plate provided on the second sheet 9 of the other sheet member.

Further, the burring 15 of the first sheet 8 and the burring 15 of the second sheet 9 that are abutted by the flange communicate with each other in the stacking direction of the sheet members 14, and a plurality of sheet members 14 are stacked and joined. The inflow side tank 11 and the outflow side tank 12 communicated by the flow path 10 are formed.
なお、上述したようにプレート基面８３、９３がロウ付けにより接合されるので、プレート基面８３、９３の接合部と、第１シート８と連結部１３との間の曲折部および第２シート９と連結部１３との間の曲折部とを離間しておくと、チューブシート６が熱膨張した場合の歪を連結部１３の曲折部で吸収しやすくなる。
Since the plate base surfaces 83 and 93 are joined by brazing as described above, the joint portion of the plate base surfaces 83 and 93, the bent portion between the first sheet 8 and the connecting portion 13, and the second sheet When the bent part between 9 and the connecting part 13 is separated, the bent part of the connecting part 13 can easily absorb the distortion when the tube sheet 6 is thermally expanded.
また、チューブシート６の長手方向では熱膨張による変形が大きくなる。したがって、チューブシート６の長手方向の一端に連結部１３を備える構成とすることで、チューブシート６が熱膨張した場合の歪を効果的に吸収できる。
Also, deformation due to thermal expansion increases in the longitudinal direction of the tube sheet 6. Therefore, by providing the connecting portion 13 at one end in the longitudinal direction of the tube sheet 6, it is possible to effectively absorb strain when the tube sheet 6 is thermally expanded.
以上述べたように、本実施形態によれば、隣接して積層されるチューブシート６の端部が連結部１３によって連結されるので、サイドプレートにチューブシートを接合して連結した場合と同等の剛性を確保することができ、また、サイドプレートが不要となるので部品点数が削減できる。

Rigidity can be ensured, and the number of parts can be reduced because side plates are not required.
また、高温の媒体が流通してチューブシート６が熱膨張した場合の歪を連結部１３で吸収できるので、チューブシート６の接合部や流路１０周辺の応力集中を緩和できる。
Further, since the strain when the tube sheet 6 thermally expands due to the circulation of a high-temperature medium can be absorbed by the connecting portion 13, the stress concentration around the joint portion of the tube sheet 6 and the flow path 10 can be alleviated.
また、チューブシート６の長手方向の一端に連結部１３を設けることで、チューブシート６が熱膨張した場合の歪を効果的に吸収でき、チューブシート６の接合部や流路１０周辺の応力集中を緩和できる。

Can be relaxed.
また、チューブシート６の第１シート８と第２シート９との接合部と、第１シート８と連結部１３との間の曲折部および第２シート９と連結部１３との間の曲折部とを離間しておくことで、チューブシート６が熱膨張した場合の歪を連結部１３の曲折部で吸収しやすくなり、チューブシート６の接合部や流路１０周辺の応力集中を緩和できる。
Moreover, the junction part of the 1st sheet | seat 8 and the 2nd sheet | seat 9 of the tube sheet 6, the bending part between the 1st sheet | seat 8 and the connection part 13, and the bending part between the 2nd sheet | seat 9 and the connection part 13 are shown.

As mentioned above, although embodiment of this invention was described, the said embodiment showed only a part of application example of this invention, and is not the meaning which limits the technical scope of this invention to the specific example of said embodiment. .
上記実施形態では、本発明をエアインテークマニホールド内に設置する水冷式チャージエアクーラに適用しているが、例えば、オイルクーラやＥＧＲクーラに適用してもよい。
In the above embodiment, the present invention is applied to a water-cooled charge air cooler installed in an air intake manifold, but may be applied to, for example, an oil cooler or an EGR cooler.
また、図４に示すように、連結部１３に溝等の凹部１３１を設けてもよい。これにより、チューブシート６が熱膨張した場合の歪をより吸収しやすくなり、チューブシート６の接合部や流路１０周辺の応力集中を緩和できる。
Further, as shown in FIG. 4, the connecting portion 13 may be provided with a recess 131 such as a groove. Thereby, it becomes easier to absorb the distortion when the tube sheet 6 is thermally expanded, and stress concentration around the joint portion of the tube sheet 6 and the flow path 10 can be alleviated.
このとき、シート部材１４の外側から内側へ向けて溝等を設けるようにすれば、溝等をプレス成形した裏側の凸部が外側に出っ張ることがないので、外形を大きくすることなく、チューブシート６が熱膨張した場合の歪を吸収する構造とすることができる。

It can be set as the structure which absorbs the distortion when 6 heat-expands.
また、上記実施形態では、積層された各チューブシート６の間にフィン７を備えた構成としているが、フィン７を備えない構成としてもよい。これにより、エアインテークマニホールド内の空気がコア５を流れるときの抵抗が減るので、吸気量を増やすことができる。つまり、フィン７を備える構成とすれば冷却効率を高くすることができ、フィン７を備えない構成とすれば流量を増やすことができる。
Moreover, in the said embodiment, although it is set as the structure provided with the fin 7 between each laminated | stacked tube sheet 6, it is good also as a structure which is not provided with the fin 7. FIG. As a result, the resistance when the air in the air intake manifold flows through the core 5 is reduced, so that the intake amount can be increased. That is, if it is set as the structure provided with the fin 7, a cooling efficiency can be made high, and if it is set as the structure where the fin 7 is not provided, the flow rate can be increased.
また、上記実施形態では、一枚のプレート１４ａから一つのシート部材１４を形成しているが、図５に示すように、複数のプレート１４ａが千鳥状に接続された形の一枚のプレート１４ｂからシート部材を形成してもよい。これにより、複数のプレート１４ａを一枚のプレート１４ｂにまとめることができるので、部品点数を削減できる。
