| 摘要 |
The heat exchanger comprises a first housing (10) provided with air channels (210) extending in a first direction (X) from an upstream end wall (13) towards a downstream end wall (14), a top plenum (20) in an upper portion of the first housing (10) above the air channels (210), and partition walls (220, 230) extending in a second direction (Y) perpendicular to the first direction (X) and dividing a lower portion of the first housing (10) into an upstream end section (31), a middle section (32), and a downstream end section (33). The air channels (210) terminate at the partition wall (230) between the middle section (32) and the downstream end section (33). The downstream end section (33) comprises at least one cone (300) extending in the first direction (X) and having a first upstream end (301) at the partition wall (230) where the air channels (210) terminate, and a second contracted downstream end (302). |

1. An air-to air heat exchanger comprising:
a first housing comprising a floor, a ceiling, an upstream end wall, a downstream end wall, and side walls, air channels extending in a first direction from the upstream end wall towards the downstream end wall in the first housing, a top plenum extending from the upstream end wall to the downstream end wall in an upper portion of the first housing above the air channels partition walls extending in a second direction perpendicular to the first direction and dividing a lower portion of the first housing below the top plenum into an upstream end section, a middle section, and a downstream end section, wherein: the air channels terminate at the partition wall between the middle section and the downstream end section, the downstream end section comprises at least one cone extending in the first direction and having a first upstream end at the partition wall where the air channels terminate, and a second contracted downstream end at the downstream end wall of the first housing or within the downstream end section in which case a further air channel is provided between the second contracted downstream end of the at least one cone and the downstream end wall of the first housing, the first upstream end of the at least one cone surrounds in a fluid tight manner in a circumferential direction all the air channels, which terminate at the partition wall between the middle section and the downstream end section. |
