Background technique
Pile power generation can generate high-temp waste gas to methanol fuel cell at work, this part high-temp waste gas needs are discharged,
Existing mode is usually that setting heat exchanger can be sufficiently sharp by the way of the hot air draft of exhaust fan, while at exhaust emission tube
With the waste heat of this part, but if exhaust fan is arranged in the sprue of exhaust pipe, fan shaft is very possible to cross thermal conductivity
Cause fan shaft damage, influence the service life of exhaust fan, if by the fan shaft of exhaust fan and blade be arranged from sprue
It just will affect hot exhaust effect apart from too short, therefore, how fan shaft adjusted according to the temperature of sprue high temperature exhaust gas
Position is to guarantee the effect of hot air draft and ensure that the service life of fan shaft is exactly the present inventor's problem to be solved.
Summary of the invention
In view of the deficienciess of the prior art, the main purpose of the present invention is to provide one kind to protect fan shaft to extend
The dedicated heat balance device of the methanol fuel cell of the service life of exhaust fan.
To achieve the above object, the present invention provides the following technical scheme that a kind of dedicated thermal balance dress of methanol fuel cell
It sets, including methanol fuel cell, the methanol fuel cell includes high-temp waste gas discharge pipe, the high-temp waste gas discharge pipe connection
There is heat exchanger, the outlet of the heat exchanger is provided with exhaust pipe, and the side of the exhaust pipe is provided with bimetal leaf, the exhausting
Machine includes fan shaft and the blade with blower axis connection, and the bimetal leaf includes the first sheet metal and second close to exhaust pipe
Sheet metal, the coefficient of expansion of first sheet metal are greater than the coefficient of expansion of the second sheet metal, and the exhaust fan is connected to second
On sheet metal.
Preferably, first sheet metal is copper sheet, and second sheet metal is steel disc.
Preferably, the outside of the exhaust pipe is provided with fan housing, be provided on the fan housing air outlet and cold air into
Mouthful.
Preferably, high-temperaure coating is coated on the inner wall of the fan housing.
The present invention has the following advantages compared with the prior art, a kind of dedicated thermal balance dress of methanol fuel cell of the invention
It sets, using bimetal leaf expanded by heating to drive exhaust fan displacement to protect fan shaft to be notheated damage, because first
The coefficient of expansion of sheet metal is greater than the coefficient of expansion of the second sheet metal, and when being heated, the first sheet metal is active layers.Second sheet metal
For passive layer, active layers can be expanded to passive layer occurs position bending, and temperature is higher, then the degree of bending is bigger, thus the second gold medal
Exhaust fan will be driven further away from the sprue of exhaust pipe by belonging to piece, the fan shaft heat damage of exhaust fan be reduced, to improve wind
The service life of arbor and exhaust fan ensures the even running of methanol fuel cell.
