| 摘要 |
The invention relates to a device for cooling waste gas, comprising an inlet area (1) for guiding a flow of waste gas, an outlet area (2) for discharging the optionally cooled waste gas, and a longitudinal housing (1) for receiving exchanging means (13) for heat exchange. The flow of waste gas flows through the exchanging means (13) on the way from the inlet area to the outlet area. The inlet area (2) and the outlet area (3) are arranged respectively on end areas of the housing (1) which are opposite in relation to the longitudinal direction. The flow of waste gas flows through the exchanging means (13) on a first flow path (16) and also on a second flow path (17) which is counter thereto.
