Unmanned aerial vehicle

Abstract

The invention relates to an unmanned aerial vehicle. The unmanned aerial vehicle comprises a battery module. The battery module comprises an inner shell and an outer shell. The inner shell defines a battery cell installation space. A heat-conducting component is arranged between the inner shell and the outer shell. The heat-conducting component comprises a component absorbing or releasing heat. The component comprises a phase change material. The inner shell is connected with a heating element and a temperature sensor. The heating element is used for heating the inner shell. The temperature sensor is used for detecting temperature of the inner shell and thereby generating a temperature signal. The temperature sensor and the heating element are connected with a control part. The control part controls the heating element according to the temperature signal generated by the temperature sensor. The temperature of the inner shell is detected by the temperature sensor. When the temperature is low, the control part controls the heating element to heat the inner shell. The heat-conducting component comprises the phase change material, and can improve the heating performance of the inner shell; when the temperature of the inner shell is relatively high, the control part controls the heating element to stop heating the inner shell and conducts heat outwards through the phase change material of the heat-conducting component to ensure the safety of a battery.

Description

technical field [0001] The present invention relates to an unmanned aerial vehicle. Background technique [0002] Battery performance is extremely important for drones, and temperature has a crucial impact on battery performance.
