Description of the drawings
Fig. 1 is the structural schematic diagram of the fuel cell turbo charge system for the embodiment for indicating the utility model.
Fig. 2 is to indicate Centrufugal compressor impeller blade pattern and discharge velocity triangle figure.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.Without departing substantially from this
In the case of utility model spirit and essence, to modifications or substitutions made by the utility model method, step or condition, belong to
The scope of protection of the utility model.
In fuel battery air feed system, the course of work of electricity auxiliary single-stage turbocharger is as follows：
Air passes through the filtering of air filter (1), into centrifugal compressor (2), the High Temperature Gas being pressurized through compressor (2)
Body is cooled by charge air cooler (9), and subsequently into fuel cell pile (5), electrochemical reaction, pile (5) occurs with hydrogen
The water that air and reaction generation is discharged enters condenser (6) together, and what is come out from condenser (6) is wet with overbottom pressure residual temperature
Air enters turbine (4), does work through turbine (4), drives compressor (2) to rotate together with motor (3), then passes through pipeline
Into mixing chamber (7), the use of turbine (4) can improve the efficiency of fuel cell power system with recovery section parasitic power；
Pile (5) tail gas still has higher temperature, if being directly discharged in air that thermal pollution can be caused, destroys natural environment and the mankind
Living environment.The water come out simultaneously from condenser (6) also enters mixing chamber, with react after be discharged to the hydrogen one of mixing chamber (7)
It is same to be discharged into air.
Centrifugal compressor is mainly formed by air intake duct, impeller body, without leaf or vaned diffuser, spiral case etc..Compressor
Impeller uses semi-open type, blade conduit side to be closed by wheel disc, and the other side is opened wide.Compressor impeller blade curve form is hypsokinesis
Swept-back, the bending direction and inclined direction of blade exit are different with impeller direction of rotation.Backward leaning vane,,, referring to Fig. 2.Back ward impeller air stream outlet absolute velocity is smaller so that air-flow flow losses in diffuser
It is small.Pressure rise is mainly completed in impeller internal, and the air-flow in impeller is acted on by centrifugal force, is not likely to produce boundary layer point
From so flow losses of the gas in impeller are smaller than in diffuser.The leaf road of back ward impeller is long, blade curvature compared with
Small, sectional area increase in leaf road is slower, and the equivalent divergent angle in the leaf road roads diffusion Du Heye is smaller, it is not easy to gas be made to be flowed in Ye Daozhong
Boundary layer separation is generated when dynamic, therefore efficiency is higher.Since fuel-cell vehicle centrifugal air compressor is to there is more stall margin
Harsh requirement is adopted different from diesel locomotive with centrifugal air compressor to make designed stall margin be extended to low discharge operating mode
Lean forward backward leaning vane export structure, using hypsokinesis swept-back exit vane structure, improves low flow rate condition centrifugal impeller
Working performance.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done should be included in the utility model
Within protection domain.
The above content is in conjunction with specific embodiments to being described in detail made by the utility model, and it cannot be said that this practicality is new
Type specific implementation is only limitted to these explanations.For those skilled in the art of the present invention, this is not being departed from
Under the premise of utility model is conceived, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the utility model guarantor
The range of shield.
