Between, coolant liquid is passed through in runner later, is taken the heat that battery generates out of under the circulation effect of coolant liquid, with the band leakage of electricity
The heat generated in the work of pond, realization cool to battery.
However the prior art is unfortunately, and cooling liquid inlet and cooling liquid outlet usually is arranged at the both ends of liquid cooling plate,
Runner is set between cooling liquid inlet and cooling liquid outlet, and runner usually flows to coolant liquid from cooling liquid inlet in a manner of fold-back
Outlet, since runner fold-back route is longer, in the runner laid on liquid cooling plate, for the flow path of coolant liquid, away from
Runner from cooling liquid inlet immediate area is preferable to the cooling effect of battery, the runner pair apart from cooling liquid inlet compared with far region
The cooling effect of battery is poor, therefore the inhomogeneities that shape battery pair cools；When coolant liquid is flowed to from cooling liquid inlet
When cooling liquid outlet, coolant liquid have just enter into cooling liquid inlet and enter runner after in certain length range when cooling effect compared with
Good, when coolant liquid close cooling liquid outlet in flowing, coolant liquid is since endothermic temperature is higher, close to coolant liquid in runner
Endothermic effect is poor within the scope of the certain length of outlet, causes coolant liquid close to cooling liquid inlet and close to cooling liquid outlet
The position temperature difference is larger, causes the battery itself temperature difference big when cooling to battery, and the battery itself temperature difference is larger to will lead to battery knot
The destruction of structure or function, therefore the setting distribution mode of conventional flow field cannot carry out uniform decrease in temperature in all directions to battery, it is cooling
Cooling effect is poor.
