Problems solved by technology

[0002] At present, in the field of lithium batteries for small unmanned aerial vehicles, lithium-ion battery packs usually do not have their own cooling measures, resulting in frequent battery overheating, shortened flight duration, and unbalanced lithium-ion battery packs, which can lead to The battery has not reached the end of its cycle life and is scrapped ahead of time
In the field of lithium batteries for large drones, refrigerators or air conditioners are usually used to cool the battery pack on the ground. When flying, take out the cooled battery pack and use it. Although this method can increase the flight time, it will also When the capacity of the battery pack is not used up and the flight ends, this passive cooling method has high cost, low cooling performance, long cooling time and no space saving

Abstract

An automatic cooling and heat dissipation device for a lithium-ion storage battery pack, in particular relates to the field of electricity consumption by high-specific energy and high-rate unmanned aerial vehicles. Several temperature sensors are arranged in the battery pack of the present invention, and the temperature sensor collects the internal temperature of the lithium-ion storage battery pack; Shen's heat flow meter uses the latent heat of the phase change material to continuously absorb the heat inside the battery pack received by the heat flow meter. The control system controls the opening and speed of the fan to accelerate the flow of airflow inside the battery pack, and then adjusts the wind direction of the fan to make the air flow Maximize the heat to the external environment through the heat dissipation window; when the internal temperature of the battery pack is lower than a certain value, the control system controls the fan to be turned off, so that the temperature of the battery pack can be kept at The set stable temperature realizes the efficient operation of the battery pack.

Description

Technical field [0001] The present invention relates to a lithium-ion battery pack automatic cooling and heat dissipation device, particularly to the field of electricity consumption characterized by high specific energy, high magnification of unmanned aerial vehicle electricity. Background [0002] At present, in the field of lithium batteries for small unmanned aerial vehicles, lithium-ion battery packs usually do not come with cooling measures, resulting in frequent overtemperature of batteries, shortening flight time, and the phenomenon of monomer imbalance of lithium-ion battery packs, which leads to batteries not reaching the end of cycle life and being scrapped in advance. Heavy will lead to the crash of the UAV; large UAV lithium battery field, usually use refrigerators or air conditioning ground cooling battery pack, wait until the flight, take out the cooled battery pack to use, although the method can increase the flight time, but also appear in the battery pack capac...
