摘要

The tool (1) has a fixed and/or flexible air channel (8), which is arranged in a housing (2). An end (9) of the air channel is turned towards a fan wheel (4) and another end (10) is turned towards a heat source (5). The air channel directs the air flow and/or distributes the air flow to cool the heat source, and is formed by disposition of flexible and/or preformed tubes. The air channel consists of individual parts (15, 15`, 18, 18`), which are firmly flanged together.
