The working principle of the utility model is that the smoke-collecting pipe of the heat exchanger collects the high-temperature flue gas from the combustion chamber of the heat exchanger through the heat-exchanging device inside the heat exchanger and collects the low-temperature flue gas after it has been fully absorbed by the heat-exchanging device. The smoke collection pipe of the heat exchanger is discharged to the outside through the chimney outside the boiler.

Preferably, the smoke collecting pipe of the heat exchanger is a hollow cylinder. The heat exchanger smoke collection pipe and the heat exchanger body are integrated to form a hollow cylindrical barrel structure, which is conducive to the smooth discharge of micro-pressure smoke; it is also conducive to the installation of general-purpose PVC pipes.

Preferably, the gas outlet of the smoke collecting pipe of the heat exchanger is a chimney connection port provided with a sealing groove, and a sealing ring is provided in the sealing groove. Place a suitable sealing ring in the sealing groove to make a good seal between the heat exchanger flue chimney connection and the installed universal piece PVC pipe chimney.

Preferably, the condensed water drainage device is a siphon device. The siphon device is designed to facilitate the discharge of condensed water.

The beneficial effects of the utility model are:

1) The design of this utility model is beneficial to casting, finishing, inspection and detection, and assembly of the heat exchanger body, and is also convenient for maintenance and cleaning of the boiler, ensuring that highly corrosive condensed water does not stay in the heat exchanger and reduces damage to the pipeline. Corrosion and clogging, increasing the efficiency and service life; the design of the flue blocking plate is convenient for maintenance and cleaning of the boiler;
