Description
Technical field
This utility model relates to a kind of novel cooling system of vehicle cold collateral resistance simulation test experiment platform, particularly to one
Kind simulate what real vehicle operating condition carrying out was tested by coolant flow situation during the internal each parts cooling of simulation piggyback pod
Pilot system.
Background technology
Along with Modern Vehicle Engine uses more compact design and has bigger power per liter, reinforcing degree is increasingly
Height, the heat flow density that electromotor produces significantly increases the most therewith, and the demand of electromotor is also improved constantly by market simultaneously, Ji Yaoman
The output that foot improves constantly, has good economy again, and in addition, the discharge standard of increasingly stringent is also to cooling system
Propose new requirement.Current almost all of engine models all suffers from how solving cooling and thermal balance under high power density
Problem, the quality of the service behaviour of cooling system, directly affect the overall performance of dynamical system.Exploitation high efficiency, highly reliable
The cooling system of property, has become electromotor and has improved power further, improves economy and crucial skill that emission performance must be broken through
Art problem.Therefore, the further investigation to cooling system of vehicle, use advanced design of Cooling System and significantly more efficient research to open
Forwarding method, the design specification being applied to Modern Design Technology proposition solution just becomes more and more urgent with strategy, has the heaviest
The practical significance wanted.
The reasonable layout of Cooling-water Flow for Engine directly influences the economy of electromotor with properly functioning.If cooling
Hypervolia, chilling temperature is low, can increase engine oil viscosity and friction power, cause the abrasion between part to aggravate, add simultaneously
The power attenuation of water pump has taken away utilizable energy, and radiation loss increases, and can reduce the economy of electromotor.If cooling water inflow mistake
Few, coolant water temperature is too high, and the water velocity that cooling water skims over cooling water cavity side is too small, makes cylinder head and relevant parts can not get
Enough coolings, affect their service life.If cooling water distribution is improper, there are flow dead or microvovtex in current district, also
Localized heat stress can be caused too high, cause part premature breakdown.Therefore suitable cooling water inflow and rational Flow Field Distribution are sought
In occupation of considerable position in engine research, and this meaning the most just flow of cooling water studied.

During 5m/s) generally 7.5 × 103～12.5 × 103Pa, water jacket resistance is generally 13 × 103～15 × 103Pa, and water dissipates
Hot device resistance 20 × 103～25 × 103Pa, drag overall is 40 × 103～53 × 103Pa.It can thus be seen that in cooling system
Each parts are all same order with the resistance of pipeline, and the efficiency of whole cooling system is suffered from important impact.In enclosed
In compulsory circulative cooling system, water pump is used to overcome bigger flow resistance to maintain necessary circular flow, if cooling system
System flow resistance is excessive will result in unnecessary energy loss, and due to drag overall excessive and result at unit fixed on water pump suction quiet
Press through low.This not only results in water pump cavitation pitting, and is easily generated steam when heat engine works, and causes pump capacity and cooling capacity
Drastically decline.Meanwhile, the pressure distribution in engine water jacket directly affects flowing and the distribution situation of coolant, greatly
Affect the efficiency of cooling system.Therefore, the research to cooling system flow resistance, to ensure coolant rate reasonable distribution with
And each critical piece coupling has considerable meaning.
In the hybrid electric vehicle application epoch the most widely, the cooling system of this kind of vehicle is the most of increasing concern.Mixed
Closing power type electric vehicle and mainly cooling down object is electromotor, electromotor, motor, set of cells and control system etc..Consider
To the feature that high/low temperature heat source component operational difference is bigger, whole cooling system is by high temperature circulation loop and cryogenic circulation loop structure
Become, high temperature heat source load and low-temperature heat source load are separated, improves the work efficiency of cooling system, make each parts in optimum temperature
Lower work.
Therefore, in order to reach experiment purpose and less experimental cost, the resistance of a kind of cooling system of vehicle cold side is proposed
Power simulation test experiment platform is of great advantage, and this testing stand has two high/low temperature two kinds circulation, is applicable to various vehicle.
