The invention relates to the technical field of heat dissipation, in particular to a heat dissipation device, an unmanned aerial vehicle, a heat dissipation system, a design method and a lighting device. The heat dissipation device comprises a base and a plurality of first fins arranged on the heat dissipation side of the base, and a first gap is formed between every two adjacent first fins in the transverse direction of the base; in the longitudinal direction of the base, at least part of the first fins are distributed to form a wavy structure, and the middle of the wavy structure is provided with a trough facing the base. And a first gap between the transversely adjacent first fins is a main heat dissipation channel. According to the heat dissipation device, the airflow vortex is formed between the barrier and the heat dissipation device, so that the flow velocity of the first fins located on the two sides of the barrier is larger, the flow velocity of the first fins right opposite to the barrier is smaller, heat can be rapidly taken out of the heat dissipation device, and the heat dissipation efficiency is improved; and the heat exchange of the whole wavy structure is relatively balanced and quicker, so that the heat dissipation capability of the heat dissipation device is stronger.
本发明涉及散热技术领域,特别是一种散热装置、无人机、散热系统、设计方法及照明装置。其中散热装置包括基座和设置于基座散热侧的多个第一翅片,其中:沿基座横向,相邻第一翅片具有第一间隙;沿基座纵向,至少部分第一翅片分布形成波浪状构造,波浪状构造的中部具有朝向基座的波谷。横向相邻第一翅片之间的第一间隙为主要散热通道。本发明散热装置,在阻挡物和散热装置之间形成气流涡旋,能够使得位于阻挡物两侧的第一翅片处的流速更大,位于阻挡物正对的第一翅片处的流速更小,这使得能够更快的将热量带离散热装置,提高散热效率;且整个波浪状构造换热较为均衡,且更为迅速,这使得散热装置的散热能力更强。
