The guide plates are vertical plate-shaped structures. The heat exchange tube bundle is arranged between adjacent guide plates, and a plurality of spoiler strips are respectively arranged on both sides of the guide plates.

[0008] In one embodiment, the spoiler strip is in a continuous S-shaped structure.
