ところで、高温側入口連結管２０のダクト２０ｃは、直径ＲＨの円筒形状であり、高温側入口面１１は、Ｌ１×Ｌ２の長方形状であるので、ダクト２０ｃと高温側入口面１１の周縁部とを連結するためにパン２０ｂがあるが、ダクト２０ｃの内側を流通する気体が高温側入口面１１の全面に均一に広がるようにするため、パン２０ｂの長さＰＨを長くする必要がある。
また、低温側入口連結管３０のダクト３０ｃは、直径ＲＬの円筒形状であり、低温側入口面１３は、Ｌ１×Ｌ３の長方形状であるので、ダクト３０ｃと低温側入口面１３の周縁部とを連結するためにパン３０ｂがあるが、ダクト３０ｃの内側を流通する気体が低温側入口面１３の全面に均一に広がるようにするため、パン３０ｂの長さＰＬを長くする必要がある。
しかしながら、パン３０ｂの長さＰＨやパン３０ｂの長さＰＬを長くすると、熱交換器１０７が大きくなるという問題点があるので、従来の熱交換器１０７では、空気流れが高温側入口面１１や低温側入口面１３の全面に均一に広がらないが、パン３０ｂの長さＰＨやパン３０ｂの長さＰＬを短くしている。
そこで、本発明は、小型化したまま、ダクトを流通する気体が入口面の隅部まで広がるようにすることができる熱交換器を提供することを目的とする。 By the way, the duct 20c of the high temperature side inlet connecting pipe 20 has a cylindrical shape with a diameter RH , and the high temperature side inlet surface 11 has a rectangular shape of L 1 × L 2 . there are pan 20b for connecting the peripheral portion, but since the gas flowing inside the duct 20c is to spread uniformly over the entire surface of the hot side inlet surface 11, necessary to increase the length P H of the pan 20b There is.
Further, the duct 30c of the low temperature side inlet connecting pipe 30 has a cylindrical shape with a diameter R L , and the low temperature side inlet surface 13 has a rectangular shape of L 1 × L 3 , so that the duct 30c and the low temperature side inlet surface 13 are formed. there are pan 30b for connecting the peripheral portion, but since the gas flowing inside the duct 30c is to spread uniformly over the entire surface of the cold side inlet surface 13, necessary to increase the length P L of the pan 30b There is.
However, when the length P L of the length P H and pan 30b bread 30b, there is a problem that the heat exchanger 107 is increased, in the conventional heat exchanger 107, the high temperature-side inlet faces the air flow not spread uniformly on the 11 and the entire surface of the cold side inlet surface 13, but to shorten the length P L of the length P H and pan 30b bread 30b.
Then, an object of this invention is to provide the heat exchanger which can make the gas which distribute | circulates a duct spread to the corner | angular part of an entrance surface, reducing in size.

Thereby, the gas which distribute | circulates the inner side of a duct distribute | circulates as a swirl flow by a swirl flow member. And if the gas which distribute | circulates the inner side of a duct reaches | attains a pan, it will spread at a short distance because it is a swirl flow. That is, the gas flowing inside the duct spreads to the corner of the entrance surface.

これにより、高温側入口連結管２０のダクト２０ｃの内側の中央部を設定方向に流通する高温の空気は、設定方向を維持したまま流通するので、高温側入口面１１の中央部に送られ、一方、ダクト２０ｃの内側の周縁部を設定方向に流通する高温の空気は、旋回流となり、高温側入口面１１の隅部に送られる。また、低温側入口連結管３０のダクト３０ｃの内側の中央部を設定方向に流通する低温の空気は、設定方向を維持したまま流通するので、低温側入口面１３の中央部に送られ、一方、ダクト２０ｃの内側の周縁部を設定方向に流通する低温の空気は、旋回流となり、低温側入口面１３の隅部に送られる。
その結果、パン３０ｂの長さＰＨやパン３０ｂの長さＰＬを短くしても、高温の空気がコア１０の複数の高温流路１６を均一に左右方向に流通するとともに、低温の空気がコア１０の複数の低温流路１７を均一に前後方向に流通することで、金属製のコア１０に熱が伝導するので、高温の空気と低温の空気との間で熱交換が効率よく行われる。 While connecting such a heat exchanger 7 into the high temperature side piping of the aircraft through which high temperature air flows, using the flange 20a of the high temperature side inlet connection pipe 20 and the flange 21a of the high temperature side outlet connection pipe 21 The flange 30a of the low temperature side inlet connecting pipe 30 and the flange 31a of the low temperature side outlet connecting pipe 31 are connected to a low temperature side pipe of an aircraft through which low temperature air flows.
Thereby, since the high temperature air which distribute | circulates the center part inside the duct 20c of the high temperature side inlet connection pipe 20 in a setting direction distribute | circulates maintaining the setting direction, it is sent to the center part of the high temperature side inlet surface 11, On the other hand, the high-temperature air flowing in the setting direction in the inner peripheral edge of the duct 20 c becomes a swirling flow and is sent to the corner of the high-temperature side inlet surface 11. Moreover, since the low temperature air which distribute | circulates the center part inside the duct 30c of the low temperature side entrance connection pipe 30 in a setting direction distribute | circulates maintaining the setting direction, it is sent to the center part of the low temperature side inlet surface 13, The low-temperature air that circulates in the setting direction along the inner peripheral edge of the duct 20 c becomes a swirling flow and is sent to the corner of the low-temperature side inlet surface 13.
As a result, even with a shorter length P L of the length P H and pan 30b bread 30b, together with the hot air flows in the lateral direction a plurality of the high-temperature passage 16 uniform core 10, cold air However, since heat is conducted to the metal core 10 through the plurality of low-temperature flow paths 17 of the core 10 uniformly in the front-rear direction, heat exchange is efficiently performed between the high-temperature air and the low-temperature air. Is called.

本発明は、例えば、高温の空気と低温の気体との間で熱交換を行う航空機用熱交換器に利用することができる。   The present invention can be used, for example, in an aircraft heat exchanger that performs heat exchange between high-temperature air and low-temperature gas.
