| 摘要 |
The invention relates to a heat exchanger for heating the ambient air of a textile machine, preferably a tenter frame, comprising a heat exchanger channel (20) for guiding through the ambient air. Said heat exchanger channel (20) is to be configured in such a way as to heat an air stream (21) that is drawn through by suction uniformly throughout the flow cross-section. According to the invention, a gas-heated heat exchanger is provided with at least two flame tubes (26, 27) which extend spatially parallel to each other and next to each other inside the heat exchanger channel (20). Heating agents flow through adjacent flame tube in opposite directions.
