| 摘要 |
A heat exchanger and a gas-fired furnace including the same are provided. The heat exchanger includes at least two heat exchange shell enclosures; and at least three rows of heat exchange tubes arranged along a furnace air flow path. Each of the heat exchange tubes defines a leaving-tube-end and an entering-tube-end, two adjacent rows are spaced from each other, the at least three rows of heat exchange tubes are connected in a leaving-tube-end to entering-tube-end fashion sequentially via the at least two heat exchange shell enclosures to define a substantially serpentine flue gas passage. |
