Description
Technical field
The present invention relates to dynamic lithium battery field, more particularly to the dynamic lithium battery of battery car and hybrid vehicle to lead
Domain, the specifically a kind of coldplate and its cooling device of the dynamic lithium battery with flow equalizing function.
Background technology
Pure electric automobile and hybrid vehicle can realize no pollution in use using battery as power source, and can
Using other non-oil resources such as coal, waterpower, can effectively solve hicle emissions and energy problem, thus worldwide obtain
To most attention.The performance and quality of these vehicles largely rely on the performance of its power battery pack configured.Temperature
Degree is to influence the vital factor of electrokinetic cell performance.When vehicle is run under different travel conditions, battery can be with difference
Multiplying power discharging, amount of heat is produced with different heat speed, uneven heat can be produced plus accumulated time and spacial influence
Aggregation, so as to cause battery pack running temperature complicated and changeable.And too high temperature can cause capacity, life-span and the energy dose-effect of battery
The reduction of rate, if the heat of battery accumulation can not shed in time, the generation of thermal runaway can be caused, battery has generation violent when serious
Expansion and the danger of blast, so battery cooling must be carried out to dynamic lithium battery, its operating temperature is set to be in preferably section.
If at this stage new energy car owner with air is cold and liquid cooling battery based on, because air cooling effect is poor, the temperature difference
Greatly, the cold scheme of liquid, parts are more, weight weight, and risk of leakage be present, so refrigerant cooling would is that a kind of heat well
Way to manage.
Refrigerant evaporation latent heat is big, and the coefficient of heat transfer is high, is the efficient battery type of cooling, and at normal temperatures and pressures, refrigeration
Agent is gaseous state, and instant battery cooling system has slight leakage, is also not in battery short circuit, damages cell condition.
It is the schematic diagram of current existing scheme battery cooling shown in Fig. 1.Automotive air-conditioning system is by compressor, condenser, swollen
Swollen valve and evaporator composition, forms refrigerant loop.Because new-energy automobile needs to carry out heat management to battery, typically in air-conditioning
On loop, a battery cooler in parallel with evaporator.And water pump, battery cooler and the coldplate in another loop constitute
Coolant circuit.Heat transfer is to coldplate caused by battery work, then is delivered to coolant, and the medium in two loops is in electricity
Heat exchange is carried out in the cooler of pond to cool to battery.
It can be seen from figure 1 that the refrigeration system of existing air conditioning for automobiles uses two cooling circuits.One is refrigerant loop,
It is mainly used in adjusting air themperature.The second is coolant circuit, is mainly used in cooling down battery or battery pack.Because two loops are adopted
With different cooling mediums, it is necessary to carry out heat transfer by a battery cooler, while it is cold to also need to a water pump driving
But liquid produces circulation.Specifically, battery cooler has cold side channel and hot-side channel, described cold side channel and evaporator
It is in parallel；Described hot-side channel is connected with coldplate.Heat passes to coolant through coldplate caused by battery.Cooled down in battery
In device, the refrigerant in the coolant and cold side channel in hot-side channel carries out heat exchange, cools after coolant release heat.Water
Pump driving coolant circulates in the loop, plays the cooling effect to battery.Thus existing battery cooling apparatus part
More, weight is big, complicated, and cost is high.Also, the mixing being made up of due to coolant generally use 50% ethylene glycol and 50% water
Thing, its advantage are that specific heat capacity is big, and temperature homogeneity is good, and develop matching simply, but also easily leakage.Once leak,
Then the ethylene glycol in coolant is possible to trigger burning, so as to damage battery, or even causes bigger security incident.
In addition, the volume of battery pack is generally worked in 300mm*300mm, conventional coldplate using single process, coldplate
Temperature distribution gradients from inlet tube to outlet are larger, thus the temperature difference of the diverse location of battery pack is larger, can not play
The effect of even cooling, and then have impact on the service behaviour of battery pack.
