A balanced device with separated channels for inlet and exit gas is comprised of a T-pipe, an internal partition belt for the pipe, and a partition belt for wind-rain cap. The T-pipe includes a main pipe and a manifold branch. The pipe is divided into two channels for inlet and exit gas by the partition belt in the form of flat or spiral, or multiple channels by multi-fin plate in the form of flat or spiral. Through an opening of a sealed space communicated with ambient, the ventilation can be operated under the effect of an elevating force generated by heat or heat combustion gas and temperature pressure and gas pressure regardless of having mechanical power. The device integrated chimney with heat exchanger has simple structure and reasonable design. The device can be used as an inlet and exit gas unit when the direct-combustion stoves or ranges used in room in the cool season or cool places. |
