| 摘要 |
The invention relates to a heat transfer unit having at least one heat exchanger (6) and at least one blower (5), wherein the heat exchanger comprises a plurality of heat transfer elements (7) permeated by a first medium or thermally conductively connected to tubes permeated by a first medium and surrounded by a second medium at the outer surface thereof, which second medium permeates the intermediate spaces (8) present between the heat transfer elements by the action of the blower. A first region (I) of the heat exchanger thereby comprises a lower distance from the blower than does a second region (II). The portion of area of the intermediate spaces (8) at the surface impinged by the second medium of the heat exchanger (6) is greater in the second region (II) thereof than in the first region (I) thereof. |
