Although the above heat dissipation scheme has the characteristics of simple design and low cost, it can be used when the working current of the lithium battery pack is very small, but in the high-power, high-current working environment of the aircraft, new heat dissipation measures must be adopted. The traditional heat dissipation method Can no longer meet the requirements of use

Embodiment Construction
[0018] In order to facilitate understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, the aviation lithium battery cooling system of the present invention includes a heat conducting plate set 100 , a radiator 200 and a cooling pipeline 300 . The cooling pipeline 300 communicates with the cooling liquid source 400, and the cooling liquid in the cooling liquid source 400 flows into the cooling pipeline 300 and circulates in the cooling pipeline 300. The cooling pipeline 300 is in contact with the heat conducting plate set 100, and the heat conducting plate set 100 and Lithium batteries are in contact for heat transfer; the coolant in the cooling pipeline 300 exchanges heat with the heat conduction plate set 100 to absorb the heat transferred by the lithium battery through the heat conduction plate set 100 , and then the cooled liquid after absorbing the heat p...

Abstract
The invention discloses a lithium battery heat dissipation system for aviation. The lithium battery heat dissipation system comprises a heat conduction plate group, a radiator and a cooling pipeline.The cooling pipeline is communicated with a cooling liquid source and then communicated between the heat conducting plate group and the radiator to form a circulating pipeline; the heat conducting plate group is composed of a plurality of heat conducting plates arranged at intervals, the cooling pipeline is branched into a plurality of cooling branch pipes corresponding to the heat conducting plates in a one-to-one mode, and the cooling branch pipes are connected with the corresponding heat conducting plates and then communicated with the cooling pipeline. According to the invention, the heatconducting plate group, the radiator and the cooling pipeline form a heat dissipation circulating pipeline of the lithium battery; the multiple flow guide plates are matched with the cooling branch pipes of the cooling pipeline branches, the heat exchange area of cooling liquid is greatly increased, and the heat dissipation effect can be effectively improved; the problem of heat dissipation of thelithium battery pack is solved, the working temperature of the aviation lithium battery is effectively controlled, the service life of the lithium battery is prolonged, the performance attenuation speed is effectively controlled, and the working safety of the lithium battery is ensured.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a cooling system for lithium batteries used in aviation. Background technique [0002] The aviation lithium battery pack is a new type of high-energy battery, which has been successfully applied to the airborne DC chemical power supply. It undertakes the functions of providing emergency power supply for key equipment and starting the engine during the use of the aircraft, which is a reliable guarantee for the safe flight of the aircraft. The lithium battery pack has the advantages of high output power and long working time in use, but it also has the disadvantage of high battery heat generation. If the lithium battery pack is used at a temperature exceeding 55°C, the performance of the lithium battery pack will be attenuated and the service life will be greatly reduced. Shortening will also increase the safety risk of lithium battery packs. [0003] At present, there a...
