Description

Double-channel wall-hung boiler heat exchanger

technical field

The utility model relates to the field of heat exchangers, in particular to a double-channel wall-hung furnace heat exchanger.

Background technique

The heat exchanger part of the existing gas wall-hung boiler adopts a double-channel design, which can be used to heat domestic hot water and heating hot water at the same time. After heating the external heating hot water, the heat of the heating hot water is transferred to the internal domestic hot water through heat exchange. The existing domestic hot water pipes use straight-through pipes. The water flows smoothly in the heating pipes, and the water temperature is high on the side of the pipe wall, while the water temperature in the center of the heating pipes is low, which causes uneven water temperature and affects heat exchange efficiency.
