Domain, the coldplate and its cooling device of specifically a kind of dynamic lithium battery.
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
