In sum, heat management device 1000 provided by the invention, with traditional add heat abstractor compared with, pyroconductivity is obviously improved, it is possible to provides for battery modules 300 and dispels the heat efficiently or add heat management.Specifically, when battery modules 300 internal heat generation, heat conduction fin 200 can absorb heat in time and conduct heat to liquid cooling plate 100, takes away heat by the circulation of coolant in liquid cooling plate 100, reaches the purpose to battery modules 300 heat radiation.When battery modules 300 works at low ambient temperatures, in liquid cooling plate 100, the hot liquid that adds of circulation transfers heat to battery modules 300 in time by heat conduction fin 200, and then is reached for battery modules 300 heat temperature raising and makes it be operated in the purpose of preferably charging and discharging state.
The foregoing is only the preferred embodiment of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
