Description
Technical Field
The utility model relates to an energy storage device technical field especially relates to a liquid cooling board supports buffer structure and has battery package of this structure.
Background
the thermal management of the power battery of the electric automobile is a key factor for determining the service performance, safety, service life and service cost of the power battery of the electric automobile. The temperature level of a lithium ion battery directly affects its energy and power performance in use. Too high or too low a temperature may affect the performance and even cause safety accidents. In addition, the working or storage temperature of the lithium ion battery can affect the service life of the lithium ion battery, the suitable temperature of the battery is about 10-30 ℃, and the over-high or over-low temperature can cause the rapid decay of the service life of the battery. Therefore, it is particularly important to maintain the temperature in the battery pack within a certain temperature range. The cooling and heating are mainly realized by cooling and heating, and the common cooling modes include air cooling, liquid cooling and direct cooling. The liquid cooling mode is widely used due to the advantages of high heat exchange coefficient of a cooling medium, large heat capacity, high cooling speed, obvious effects of reducing the highest temperature and improving the consistency of the temperature field of the battery pack and the like.
The liquid cooling system generally comprises a liquid cooling plate, a liquid cooling pipeline, a cooling pump, a cooling valve and the like. The liquid cooling plate is one of the most critical parts in the liquid cooling system of the battery pack, and the support and buffering of the liquid cooling plate are particularly important. A common supporting and cushioning solution is to support the liquid cooling plate by a stainless steel plate spring. The leaf spring direct mount guarantees the stability of liquid cooling board on the battery package box.
However, the existing supporting and buffering scheme has the following disadvantages: firstly, the liquid cooling plate needs to be subjected to vibration and impact load tests, but the plate spring is made of hard elastic materials, and when the plate spring is impacted, the impact can be quickly absorbed, but the released impact can also generate large impact on the liquid cooling plate. The liquid cooling plate is supported by the plurality of plate springs, so that the local area of the liquid cooling plate is stressed excessively, the whole stress is not uniform, and the stability of the whole supporting structure is poor. Secondly, the plate spring is connected with the box body through mechanical structures such as nuts, and when the automobile runs for a long time, abrasion is easily generated between the plate spring and the box body and between the plate spring and the liquid cooling plate. Particularly, the liquid cooling plate and the box body are generally made of aluminum, the risk of deformation and leakage exists, and the leakage of a liquid medium seriously harms the safety of the battery pack. The plate spring and box connection structure is broken, the plate spring can fall off, the liquid cooling plate is inclined and separated, and the cooling efficiency is poor. Furthermore, the resilience of the plate spring is related to the deformation of the plate spring structure, and the plate spring needs to be high enough to generate sufficient resilience to support the liquid cooling plate, which may reduce the available space of the battery pack and reduce the capacity of the battery pack. In addition, the plate spring is a metal piece, has good heat conductivity, and is directly contacted with the liquid cooling plate to cause the need of arranging a layer of heat preservation cotton on the periphery of the box body, so that the battery pack shell is prevented from influencing a liquid cooling system, and the cost is increased.
