Cooling system is the important component of engine, and according to relevant information introduction, 50% or so of vehicle failure is come from
Engine, and 50% or so of engine failure is as caused by cooling system failure, it can be seen that cooling system can in automobile
Important function in property.Cooling system not only can generate significant impact to the reliability of engine, and be also to influence to start
An important factor for mechanomotive force and economy, function are ensuring that engine under any loading condiction and under working environment
It can work normally and reliably under most suitable state of temperature.As the revolving speed and power of Modern Engine are continuously improved, hair
Motivation thermic load is higher and higher, and the discharge and noise control to engine are also increasingly stringenter, thus to engine-cooling system
Design and research it is also more and more deep.The engine of especially currently employed boosting type gradually increases, and engine with supercharger is general
Compact-sized, thermic load and mechanical load generally improve, more sensitive to the cooling problem of engine, are also cooling system proposition
Higher requirement.On the other hand, high traditional cooling system big energy-consuming, especially cooling fan energy consumption is also urgently to be solved asks
Topic.Nervous in current energy supply, in the case that oil price constantly rises, reducing cooling system energy consumption seems for engine energy-saving
It is particularly significant.Under the premise of meeting cooling require, raising cooling efficiency, reduction energy consumption reduce noise and have become as much as possible
The main direction of studying of cooling system.The continuous renewal of the extensive use of new technology, new material, design means and manufacturing process,
Also advantage is provided to rationally design engine-cooling system.Cooling efficiency is improved, energy consumption is reduced, is engine cool system
Following developing direction of system, therefore Optimal Structure Designing is carried out to cooling fan, the influence expansion to heat spreader structures to performance
Research, and the Optimized Matching of cooling fan and radiator.
Summary of the invention
The invention patent technical problems to be solved are a kind of optimization methods of automobile cooling system.
The present invention solves the optimization method that technical solution used by above-mentioned technical problem is a kind of automobile cooling system, packet
Include engine water tank, power supply, cooling fan and controller, the prioritization scheme of the cooling fan are as follows:
1) under the premise of given associated technical parameters, air quantity of fan and wind pressure is calculated, the knot of optimization design fan is passed through
Structure parameter finds out optimal fan internal diameter DrOuter diameter D2With rotation speed of the fan n and radial clearance SrThe power N for consuming fanfMost
It is small；
2) optimal fan internal diameter D is solvedrOuter diameter D2With rotation speed of the fan n and radial clearance SrLater, by Dr D2n Sr
As known parameters, then blade parameter is calculated, makes the hydraulic efficiency η of fanhHighest；
3) optimized mathematical model is established, is solved
It is more further than above scheme, when the signal acquisition, it can be taken multiple measurements with two same type sensors,
Peak and minimum are rejected, the sampling value as the secondary measurement is averaged.
More further than above scheme, the controller integrally uses modularized design, as Intelligent Single-Chip Based controls mould
Block.
More further than above scheme, the power supply powers to entire automobile cooling system.
The beneficial effects of the present invention are: consuming power and fan using variable-metric method and Means of Penalty Function Methods with cooling fan
Hydraulic efficiency is as optimization aim, using mixed punishable function method, using Fortran Programming with Pascal Language, to cooling fan of engine
Calculating is optimized in structural parameters.
Detailed description of the invention
Fig. 1 is structure connection diagram of the invention.
Specific embodiment
It is clear to be more clear technical solution of the present invention, below the present invention is described further, any pair of sheet
The technical characteristic of inventive technique scheme carries out the scheme that equivalencing is obtained with conventional reasoning and each falls within the scope of the present invention.
A kind of optimization method of automobile cooling system, including engine water tank, power supply, cooling fan and controller, it is described
The prioritization scheme of cooling fan are as follows:
1) under the premise of given associated technical parameters, air quantity of fan and wind pressure is calculated, the knot of optimization design fan is passed through
Structure parameter finds out optimal fan internal diameter DrOuter diameter D2With rotation speed of the fan n and radial clearance SrThe power N for consuming fanfMost
It is small；
2) optimal fan internal diameter D is solvedrOuter diameter D2With rotation speed of the fan n and radial clearance SrLater, by Dr D2n Sr
As known parameters, then blade parameter is calculated, makes the hydraulic efficiency η of fanhHighest；
3) optimized mathematical model is established, is solved
It determines optimization aim and founding mathematical models, prepares a computer program, solve optimum structure parameter, optimize cooling wind
Fan structure.The practical application value of fan structure parameter and computer program after optimization is verified, and with before optimization
Fan is compared.The air quantity of fan is one of important indicator of fan performance, under the premise of fan consumption power is identical, is wished
The air quantity of fan of keeping watch is the bigger the better；Or in the case where the air quantity of fan is certain, the power consumption of fan is minimum, and engine is normal
Sheet metal fan efficiency is lower, and general only 30% one 50%, the raising of fan efficiency helps to reduce energy consumption.
Signal acquisition: the acquisition to signal parameters such as engine water temperature, air inflow size pressure, engine speed, very
Important, they are the foundations that intelligent control is realized.When signal acquisition, it can be taken multiple measurements, be picked with two same type sensors
Except peak and minimum, it is averaged the sampling value as the secondary measurement.Use average value that can reduce measurement as measured value
Error mentions high control precision.
Modularized design: control system integrally uses modularized design, such as Intelligent Single-Chip Based control module.Automatically reset mould
Block, data acquisition and signal conditioning module, A/D analog-to-digital conversion module, in this way convenient for extension, strong applicability.Intelligence control system
The valve that not only can control thermostat may be simultaneously used for controlling automatically controlled cooling fan, automatically controlled wind deflector etc., as long as increasing
Different control device, so that it may to there is different purposes.
