Description
Technical field
The present invention relates to methanol fuel cell technical field, particularly to a kind of methanol fuel cell special thermal balance dress
Put.
Background technology
Methanol fuel cell operationally pile generating can produce high-temp waste gas, and this part high-temp waste gas needs to be discharged,
Existing mode is typically with the mode of air exhauster hot type wind, and arrange heat exchanger at exhaust emission tube can be fully sharp simultaneously
With the waste heat of this part, but if air exhauster being arranged on the sprue of exhaustor, then fan shaft is very possible crosses thermal conductance
Cause fan shaft damages, and affect the service life of air exhauster, if by the fan shaft of air exhauster and blade setting from sprue
Hot exhaust effect will be affected apart from too short, therefore, how adjust fan shaft according to the temperature of high-temp waste gas in sprue
Position is to ensure the effect of hot type wind and to ensure the problem to be solved of the present inventor just in service life of fan shaft.
Summary of the invention
The deficiency existed for prior art, present invention is primarily targeted at offer one and fan shaft can be protected to extend
The special heat balance device of methanol fuel cell in the service life of air exhauster.
For achieving the above object, the technical scheme is that a kind of methanol fuel cell special thermal balance dress
Putting, including methanol fuel cell, described methanol fuel cell includes high-temp waste gas discharge pipe, and described high-temp waste gas discharge pipe connects
Having heat exchanger, the outlet of described heat exchanger to be provided with exhaustor, the side of described exhaustor is provided with bimetal leaf, described convulsion
Machine includes fan shaft and the blade being connected with fan shaft, and described bimetal leaf includes the first sheet metal and second near exhaustor
Sheet metal, the coefficient of expansion of described first sheet metal is more than the coefficient of expansion of the second sheet metal, and described air exhauster is connected to second
On sheet metal.
Preferably, described first sheet metal is copper sheet, and described second sheet metal is steel disc.
Preferably, the outside of described exhaustor is provided with fan housing, described fan housing is provided with air outlet and cold air enters
Mouthful.
Preferably, the inwall of described fan housing is coated with high-temperaure coating.
The present invention has the advantage that relative to prior art, a kind of methanol fuel cell special thermal balance dress of the present invention
Put, its utilize bimetal leaf expanded by heating thus drive air exhauster displacement to protect fan shaft to be notheated damage because first
The coefficient of expansion of sheet metal is more 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 expand to passive layer and position bending occurs, and temperature is the highest, then the degree bent is the biggest, thus the second gold medal
Belonging to sheet will drive air exhauster further away from the sprue of exhaustor, reduces the fan shaft heat damage of air exhauster, thus improves wind
Arbor and the service life of air exhauster, ensure the even running of methanol fuel cell.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of special heat balance device of methanol fuel cell, including methanol fuel cell 1, described methanol fires
Material battery 1 includes high-temp waste gas discharge pipe 2, and described high-temp waste gas discharge pipe 2 connects heat exchanger 3, the outlet of described heat exchanger 3
Being provided with exhaustor 4, the side of described exhaustor 4 is provided with bimetal leaf 5, and described air exhauster 8 includes fan shaft 9 and and blower fan
The blade 10 that axle 9 connects, described bimetal leaf 5 includes the first sheet metal 6 and the second sheet metal 7 near exhaustor 4, described the
The coefficient of expansion of one sheet metal 6 is more than the coefficient of expansion of the second sheet metal 7, and described air exhauster 8 is connected on the second sheet metal 7.
The special heat balance device of a kind of methanol fuel cell 1 of the present invention, it utilizes bimetal leaf 5 expanded by heating thus carries
Dynamic air exhauster 8 displacement protects fan shaft 9 to be notheated damage, because the coefficient of expansion of the first sheet metal 6 is more than the second metal
The coefficient of expansion of sheet 7, when being heated, the first sheet metal 6 is active layers.Second sheet metal 7 is passive layer, and active layers can be to passive layer
Expand occur position bending, temperature is the highest, then the degree bent is the biggest, thus the second sheet metal 7 will drive air exhauster 8 further away from
The sprue of exhaustor 4, reduces fan shaft 9 heat damage of air exhauster 8, thus improves the use longevity of fan shaft 9 and air exhauster 8
