Lithium battery module for new energy vehicles

Abstract

The application provides a lithium battery module for a new energy vehicle, and belongs to the technical field of lithium batteries.The lithium battery module comprises a battery compartment, a condenser and a connecting pipeline.The battery compartment comprises a main evaporation base body and an auxiliary evaporation gland, and the auxiliary evaporation gland and the main evaporation base body are detachably connected; the main evaporation base body is internally provided with a first evaporation cavity, and the auxiliary evaporation gland is internally provided with a second evaporation cavity; the condenser is installed above the outside of the battery compartment; and a low-boiling-point phase change working medium realizes siphon self-circulation by phase change in the condenser and the first evaporation cavity and the second evaporation cavity.The application specifically provides a lithium battery module for a new energy vehicle, which utilizes the phase change characteristics that a low-boiling-point phase change working medium absorbs heat and boils in an evaporation cavity and releases heat and condenses in a condenser, and combines the height difference between the condenser and the evaporation cavity to form a heat-siphon self-circulation lithium battery module for a new energy vehicle.
