Abstract

A battery (100, 200, 300) and its heat management device (101, 301), and a UAV (10) having the battery, the heat management device (101, 301) comprising: a heat conduction device with a cavity (311) Shell (110, 210, 220, 310); at least one heat conducting frame (320) installed in the cavity (311); wherein, the heat conducting frame (320) conducts heat with the inner wall of the cavity (311) connection, so that the heat of the heat conducting frame (320) can be conducted to the heat conducting shell (110, 210, 220, 310); the heat conducting frame (320) separates the cavity (311) for accommodating electric a plurality of battery cell positions (120, 330) for the core (103, 303), and the heat conducting frame (320) can be in contact with the battery cell (103, 303) to conduct heat. The above-mentioned heat management device (101, 301) can improve the service life of the battery, eliminate the temperature difference between two adjacent battery cells (103, 303), is small in size, light in weight, and low in cost. The choice of the battery Advantages such as less limitations.

Description

technical field [0001] The present invention relates to an energy storage device, in particular to a battery, a thermal management device thereof, and a UAV (Unmanned Aerial Vehicle, unmanned aerial vehicle) having the battery. Background technique [0002] When the UAV's power battery is used, its high-rate discharge will generate a lot of heat, resulting in a serious problem of temperature rise. In addition, the power battery of UAV is often connected in series and parallel with multiple cells, the internal heat of the battery is not easy to dissipate, the internal temperature is uneven, and the local temperature rise is too high, which further accelerates battery attenuation, shortens battery life, and affects safety performance. Therefore, it is necessary to install a thermal management device to solve the problem of temperature rise and uneven temperature of the battery core. [0003] The traditional power battery structure for UAV is that multiple cells are directly s...
