Description
Technical Field
The invention relates to a battery thermal management device.
Background
With the increasing world energy demand, energy crisis and environmental pollution are caused. The energy consumption and the waste emission brought by the traditional fuel automobile account for a great proportion. Therefore, in order to solve these problems, the automobile industry is turning from internal combustion engine-driven automobiles to new energy automobiles in many countries.

The lithium ion battery has the advantages of high energy density, long service life and the like, and is a preferred power source of the electric automobile. The performance of the battery is highly dependent on temperature. The battery thermal management system enables the battery pack to operate in a proper temperature range, which not only has an important influence on the performance of the battery pack system, but also is important for the safety and stability of the battery pack. The primary function of the battery pack thermal management system is to maintain the average temperature of the battery cells within an optimum operating temperature range, wherein the individual battery pack temperatures in the battery pack vary by less than 5 ℃.
Currently, the main battery thermal management systems are mainly air cooling, liquid cooling, and phase change material cooling. Air cooling is the preferred cooling option for automotive manufacturers among all currently available thermal management systems. This can be attributed to its low operating cost, compact design and good reliability. On the contrary, however, air cooling systems also have considerable drawbacks, such as their low cooling capacity, limited flow and uneven temperature distribution upstream and downstream. Air cooling is compared to the liquid cooling, and the cooling effect is more outstanding, but equipment is comparatively complicated, and will guarantee the leakproofness of device, prevents revealing of coolant liquid. The phase-change material has low heat conductivity coefficient and low potential heat storage capacity, and has certain limitations such as easy leakage, odor emission, toxicity, corrosivity and the like.
