Abstract

A battery (100, 200, 300), a heat management apparatus (101, 301) thereof and a UAV (10) having the battery. The heat management apparatus (101, 301) comprises: a heat conduction shell (110, 210, 220, 310) having an accommodation cavity (311), and at least one heat conduction frame (320) mounted inside the accommodation cavity (311), wherein the heat conduction frame (320) is connected to an inner wall of the accommodation cavity (311) in a heat-conducting manner, so that the heat of the heat conduction frame (320) can be conducted to the heat conduction shell (110, 210, 220, 310); the heat conduction frame (320) divides the accommodation cavity (311) into multiple battery cell bin positions (120, 330) for accommodating battery cells (103, 303); and the heat conduction frame (320) can be in contact with the battery cells (103, 303) so as to conduct the heat generated by the battery cells (103, 303). The above-mentioned heat management apparatus (101, 301) has the advantages of being able to improve the service life of a battery and eliminate a temperature difference between two adjacent battery cells (103, 303), a smaller volume, a lighter weight, a lower cost and less limitation on the selection of a battery.

Description

technical field [0001] The present invention relates to an energy storage device, in particular to a battery and its heat management device, and a UAV (Unmanned Aerial Vehicle, unmanned aerial vehicle) with 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 stacked a...
