Technical field
It uses and moves the utility model is related to a kind of dynamic lithium battery cooling device more particularly to pure electric automobile or hybrid power
Power lithium battery cooling device, specifically a kind of push-in dynamic lithium battery cooling device.
Background technology
Using battery as power source no pollution may be implemented, and can in pure electric automobile and hybrid vehicle in use
Using other non-oil resources such as coal, waterpower, hicle emissions and energy problem can be effectively solved, thus are worldwide obtained
To most attention.The performance and quality of these vehicles largely rely on the performance for the power battery pack that it is configured.Temperature
Degree is to influence the vital factor of power battery performance.When vehicle is run under different driving conditions, battery can be with difference
Multiplying power discharging generates amount of heat, in addition accumulated time and spacial influence will produce uneven heat with different heat rates
Aggregation, it is complicated and changeable so as to cause battery pack running temperature.And excessively high temperature can lead to capacity, service life and the energy dose-effect of battery
The reduction of rate can lead to the generation of thermal runaway if the heat of battery accumulation can not shed in time, and battery has generation violent when serious
The danger of expansion and explosion makes its operating temperature be in preferably section so battery cooling must be carried out to dynamic lithium battery.
If new energy car owner liquid cooling is but based on battery at this stage, and liquid cooling apparatus mainly uses welded type liquid cooling plate,
Since current liquid cooling plate suqare is big, welding procedure difficulty is big, it is difficult to which product is indeformable after guarantee.The quantity increase of cooling tube is got over
More, the area of liquid cooling plate is bigger, and defect becomes apparent from.
