Abstract

A power battery module based on air, hot pipe and phase-change material coupled cooling belongs to power battery modules. Each cylinder of a trifolium-type sleeve of the power battery module is inside provided with a plurality of cylindrical cell individuals in serial connection, and all cylinder battery groups have same quantity of the cell individuals in serial connection, and are in parallel connection. The power battery module reasonably combines the advantages of air cooling, hot-pipe cooling and phase-change material cooling, a hot pipe exports heat in cell bottoms of which the heat radiation property is relatively bad, a fin is used to export heat in the phase-change material and the hot pipe, and air natural convection or forced convection cooling is reasonably employed for assisting heat radiation of the fin. The battery module is obvious in battery temperature-controlling effect, simple and compact in structure and convenient for mounting and dismounting, and a large battery group can be formed by connecting multiple modules. A plurality of the power battery modules can be properly combined and designed for being applied to various electric equipment driven by power batteries, and wide market prospect is provided.

Description

technical field [0001] The invention relates to a power battery module, in particular to a power battery module based on coupled cooling of air, heat pipes and phase change materials. Background technique [0002] With the development of the global economy, energy and the environment are facing severe challenges, and the transportation industry is a major player in energy consumption and pollutant emissions. Since new energy vehicles, especially electric vehicles, have obvious advantages in energy saving and emission reduction, the development of electric vehicle strategy is of great significance. At present, the main driving force of electric vehicles is provided by the battery pack composed of single cells, and the temperature level and temperature uniformity have a great influence on the capacity and life of the battery pack. When the power battery is running at high power, the battery generates a lot of heat. If it cannot be dissipated in time, the temperature of the ba...
