Unmanned aerial vehicle

The invention relates to an unmanned aerial vehicle. The unmanned aerial vehicle comprises a battery module, the battery module comprises a monomer and a housing body for accommodating the battery monomer, and a part positioned between the battery monomer and the housing body for absorbing or releasing heat, wherein the part comprises a phase-transition material. The part is a box arranged along the inner circumference of the housing body, and the phase-transition material is packed in the box. The phase-transition material is arranged between the battery monomer and the housing body, when thetemperature is low, the phase-transition material releases heat, and the working ambient temperature of the battery is guaranteed. When the temperature is high, the phase-transition material absorbsheat, the battery heat is effectively transferred, the safety can be guaranteed, and the safe flight of the unmanned aerial vehicle can be guaranteed. 本发明涉及种无人飞机，包括电池模组，所述电池模组包括：电池单体和容纳所述电池单体的外壳体，于所述电池单体与所述外壳体之间设置用于吸收或释放热能的部件，
