The utility model proposes a kind of heat exchangers of gas heater.
In the utility model embodiment, as shown in Figure 1 to Figure 3, the heat exchanger of the gas heater include shell (not
Mark) and heat exchange main body 30.Wherein, shell includes opposite along first direction and spaced two collector plate 10, two collector plates
It is formed with heat exchanging chamber 100 between 10, intake tunnel, exhalant canal, and connection intake tunnel and water outlet are formed in collector plate 10
The bypass passageways in channel.The main body 30 that exchanges heat is set to heat exchanging chamber 100, and heat exchange main body 30 includes heat exchanging pipe, and heat exchanging pipe is series at
Heat exchanger channels are formed between two collector plates 10, and the water inlet end of heat exchanger channels is connected to intake tunnel, the water outlet of heat exchanger channels
End is connected to exhalant canal.
In the present embodiment, the heat exchanger of the gas heater is used to carry out hot friendship with the high-temperature flue gas after combustion heating
It changes, to provide hot water.Specifically, shell includes two collector plates 10 being oppositely arranged, and is formed with intake tunnel in collector plate 10, goes out
Aquaporin and bypass passageways, wherein intake tunnel are connected to water inlet 115, and exhalant canal is connected to water outlet 116.Exchange heat main body
30 are set in the heat exchanging chamber 100 formed between two collector plates 10, and the heat exchanging pipe for the main body 30 that exchanges heat is connected with two collector plates 10
It is logical so that outer low temperature water can enter heat exchanging pipe from intake tunnel and carry out heat exchange type at defeated from exhalant canal again after high-temperature water
Go out.Bypass passageways are mixed the part water at low temperature in intake tunnel to be drained in exhalant canal with the high-temperature water after heat exchange
It closes, to achieve the purpose that reduce water cut-off temperature-rising.It is understood that in order to which the water ensured in bypass passageways is unlikely to influence combustion gas
Water temperature when water heater normal use, the section of general bypass passageways are less than the section of intake tunnel.
Wherein, can be that single snakelike heat exchange tube is constituted or more exchange heat about the concrete structure of heat exchanging pipe
Pipe passes through two collector plates, 10 one snakelike heat exchange tube road of formation concatenated with one another.Intake tunnel, water outlet are limited inside collector plate 10
