Description
Technical Field
The utility model relates to the technical field of cooling systems for battery packs, in particular to a micro-channel liquid cooling and air cooling composite cooling system for a power battery.
Background
The lithium ion battery has higher specific capacity, good charge and discharge performance, long cycle life and the like, and the comprehensive performance is superior to that of other types of batteries, so that the lithium ion battery is widely applied to the fields of automobiles, electronic products and energy storage.
In order to greatly improve the energy density, the internal structure of the power battery pack for the electric automobile is more compact, and a sufficient effective heat dissipation space is lacked, so that a large amount of heat generated by the battery in the operation process is difficult to dissipate, and the temperature of the battery is increased. The battery operates at a high temperature, which not only affects the performance and life of the battery, but also causes safety problems due to thermal runaway.
The cooling system of the battery mainly comprises components such as a liquid cooling plate, a pipeline and the like, wherein the traditional liquid cooling plate is usually positioned at the bottom or the upper part of a battery pack, and the battery is cooled in a single-sided cooling mode. The manner of single-sided cooling tends to result in the following problems:
(1) The temperature difference of the battery pack is large.
The liquid cooling plate is cooled on one side, so that the temperature of the side end of the battery pack at the cooling surface is higher, and particularly under the condition of high-rate charge and discharge, the temperature difference caused by heat generation and heat dissipation is larger.
(2) The single-side cooling heat exchange efficiency is low.
Because the single side of the liquid cooling plate is contacted with the battery pack, only one side of the battery pack can be contacted, and the heat exchange efficiency of the liquid cooling plate is limited. Therefore, the heat dissipation effect of the battery can only solve the heat dissipation of the edge part of the battery, but not the heat dissipation of the inside of the battery, so that the temperature difference of the inside of the battery is large, and the service life and the safety of the battery are influenced.
(3) The single air cooling heat exchange efficiency is low.
The air cooling heat dissipation effect using air as a medium obviously cannot meet the current heat dissipation requirement. Moreover, air cooling is greatly affected by the temperature of the outside air, and particularly, the heat transfer efficiency is drastically reduced in the superheated or supercooled weather condition.
Therefore, a novel micro-channel liquid cooling and air cooling composite cooling system for a power battery is needed to solve the problems, so that the four surfaces of the single battery are cooled simultaneously, and the heat exchange area is increased; the multi-surface cooling also reduces the temperature difference between the single batteries and improves the integration level, thereby improving the utilization rate of the internal space of the battery; and utilize the medium in the liquid cooling structure to cool down to the air, improved the heat exchange efficiency of air cooling, and then promoted holistic heat exchange efficiency.
