Abstract

The invention discloses a heat exchange device. The heat exchange device comprises a hollow outer shell, a main heat exchange tube layer, a condensation heat exchange tube layer and a first baffle, wherein the main heat exchange tube layer, the condensation heat exchange tube layer and the first baffle are arranged in the outer shell and are hollow. First fluid channels are formed in the wall bodyof the main heat exchange tube layer, a first gas channel communicating with the inner side and the outer side is formed on the wall body of the main heat exchange tube layer, and the first gas channel is distributed between the first fluid channels; the condensation heat exchange tube layer sleeves the periphery of the main heat exchange tube layer at intervals, and second fluid channels communicating with the first fluid channels are formed in the wall body of the condensation heat exchange tube layer; and the first baffle is located between the main heat exchange tube layer and the condensation heat exchange tube layer, a plurality of first flue gas through holes communicating with the inner side and the outer side are formed in the first baffle, and the plurality of first flue gas through holes are opposite to the first fluid channels and are distributed in the direction of the first fluid channels. According to the heat exchange device, the flue gas temperature distribution is more uniform, the heat exchange is more sufficient, heat waste is reduced, and the heat exchange efficiency is greatly improved.

Description

technical field

[0001] The invention relates to a heat exchange device, in particular to a heat exchange device. Background technique

[0002] In the prior art, most of the heat exchangers use finned tube heat exchangers, and the combustion chamber part adopts water tube shells. Since the contact surface between the water tubes and the shell is small, the heat available for the water tubes is less, and most of the heat is transferred. To the surface of the shell, the surface temperature of the shell is high, causing a lot of waste of heat, and the heat conversion efficiency is low. Some condensers add a condensing heat exchanger after the main heat exchanger to increase the heat exchange stroke, but the sealing requirements between the main heat exchanger and the condensing heat exchanger are high, and the overall efficiency is difficult to improve.
