The top cover 120 is installed on the guide shell 110 and seals one end of the inner shell 112. The smoke exhausting assembly 130 is installed on the guide cylinder 110, and a smoke exhausting channel 131 communicated with the second guide chamber 1122 is formed in the smoke exhausting assembly 130.
In the above flow guiding device 100, during the combustion process, the high-temperature flue gas enters the first flow guiding cavity 1121, and contacts the heat exchange tube 200 to perform heat exchange, so as to achieve the purpose of heating the cold fluid. Because the top cover 120 is sealed at one end of the inner cylinder 112, the high-temperature flue gas which just enters is prevented from being directly discharged from one end of the inner cylinder 112, the residence time of the high-temperature flue gas in the first flow guide cavity 1121 is prolonged, the heat loss is reduced, and the heat exchange efficiency of the whole machine is improved.
