The invention relates to the technical field of new energy vehicles, and discloses a new energy automobile battery compartment temperature control system, which comprises a battery compartment, a thermal insulation compartment and a liquid cooling plate; a water inlet pipe of the liquid cooling plate is communicated with a thermostatic valve, and two water inlet pipes of the thermostatic valve arerespectively communicated with a hot compartment and a cold compartment. According to the new energy automobile battery compartment temperature control system, high-temperature cooling liquid and low-temperature cooling liquid are stored in the hot compartment and the cold compartment correspondingly; on the premise that the electric quantity of a battery is not consumed, the constant temperaturecan be maintained for a long time, and energy consumption of a new energy automobile is reduced; meanwhile, heat emitted by work of a motor and the battery is actively absorbed, and heat preservationenergy consumption of the battery is further reduced; the shrink film blows intermittently, so that air convection is generated in the thermal insulation compartment, the temperature in the thermal insulation compartment is more uniform, cooling liquid is disturbed in the process that water flow enters again and the shrink film blows up, the temperature of the upper surface and the temperature ofthe lower surface of a water column are evenly mixed, and the temperature of the water on the upper surface can still keep small temperature change after absorbing heat.
本发明涉及新能源汽车技术领域,且公开了一种新能源汽车电池仓温控系统,包括电池仓、保温仓和液冷板,所述液冷板的进水管连通有恒温阀,所述恒温阀的两个进水管分别连通有热仓和冷仓。该新能源汽车电池仓温控系统,热仓和冷仓内分别存储高温和低温的冷却液,在不消耗电池电量的前提下,可以维持较长时间的恒温,减少新能源车能耗,同时主动吸收电机和电池工作散发的热量,进一步减少电池的保温耗能,其次,收缩膜间歇时鼓动,使得保温仓内产生空气对流,使得保温仓内的温度更加均匀,并且在水流重新进入使收缩膜鼓起的过程中,会使冷却液扰动,使水柱上下表面温度混合均匀,上表面水温在吸收热量后仍能维持较小的温度变化。
