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

The utility model discloses an automatic cooling and radiating device for a lithium ion storage battery pack, and particularly relates to the field of high-specific-energy and high-magnification unmanned aerial vehicle power utilization. A plurality of temperature sensors are arranged in the battery pack, and the temperature sensors collect the internal temperature of the lithium ion storage battery pack; the control system is used for processing temperature data acquired by the temperature sensor; when the temperature in the battery pack is higher than a certain value, a phase-change materialis used as a heat flow meter of the heat sink, latent heat of the phase-change material is used for continuously absorbing heat, received by the heat flow meter, in the battery pack, the control system controls starting and rotating speed of the fan and accelerates flowing of air flow in the battery pack, and the air flow brings the heat to the external environment to the maximum extent through aheat dissipation window by adjusting the air direction of the fan. 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 is kept at a set stable temperature under a high-magnification use condition of the battery pack, and efficient operation of the battery pack is realized.

Description

technical field [0001] The invention relates to an automatic cooling and heat dissipation device for a lithium-ion storage battery pack, in particular to the field of power consumption for unmanned aerial vehicles characterized by high specific energy and high rate. Background technique [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 an...
