Abstract

The invention discloses a lithium battery pack heat dissipation structure which comprises a battery bottom fixing plate, a 48V hybrid battery, an airflow driving device and a battery fan cover, wherein the 48V hybrid battery is installed on the battery bottom fixing plate, the airflow driving device is connected to the outside of the 48V hybrid battery in a sleeving mode, the bottom of the airflow driving device is connected to the battery bottom fixing plate, the battery fan cover covers the periphery of the 48V hybrid battery and the airflow driving device, and the bottom of the battery fan cover is connected to the battery bottom fixing plate. The airflow driving device comprises an airflow driving plate and a spring, the periphery of the 48V hybrid battery is sleeved with the airflow driving plate, one end of the spring is connected to the battery bottom fixing plate, and the other end of the spring is connected to the airflow driving plate. Through the structural design, the structural airflow driving plate in the battery moves to drive internal air to flow by utilizing inertia force in the moving process of the whole vehicle, so that the effect of cooling the battery is achieved, and other energy sources are not needed in the process. The invention further discloses a lithium battery pack heat dissipation method.

Description

technical field [0001] The invention belongs to the technical field of new energy hybrid vehicles, and in particular relates to a heat dissipation structure of a lithium battery pack and a heat dissipation method thereof. Background technique [0002] With the development of the new energy automobile industry, the performance requirements for new energy batteries are getting higher and higher, and the safety requirements are also increasing; on the basis of ensuring safety, battery performance improvement is a key indicator for battery evaluation. During the use of batteries The influence of temperature on the battery is a very critical factor. Especially for batteries like hybrid vehicles, a large amount of heat will be generated in a short period of time during battery use. This heat must be dissipated through the thermal conductivity of the battery and the casing to prevent the internal temperature of the battery from being too high and affecting safety and performance; ...
