The invention discloses an unmanned aerial vehicle with a circuit board heat dissipation structure. The cavity of the unmanned aerial vehicle body is divided into an upper cavity and a lower cavity bya partition plate; the section of a circuit board heat dissipation component is in a shape of Chinese character 'hui', one side edge of the circuit board heat dissipation component is open, parallelheat conduction plates are arranged at the bottom of a top plate and the top of a bottom plate of the circuit board heat dissipation component; circulating channels, which are communicated with each other, are formed in the top plate and the bottom plate; a circuit board is arranged between the two heat conduction plates; the liquid inlet end of a heat exchanger is communicated with the outlet endof the circulating channel through a conduit; a liquid storage tank is arranged in the lower cavity; a cooling medium is arranged in the liquid storage tank, the liquid inlet end of the liquid storage tank is communicated with the liquid outlet end of the heat exchanger through a conduit; the liquid inlet end of a liquid pump is communicated with the liquid outlet end of the liquid storage tank through a conduit, the liquid outlet end of the liquid pump is communicated with the inlet end of the circulating channel through a conduit, compared with a traditional heat dissipation structure witha heat dissipation fan, the circuit board is surrounded, comprehensive heat dissipation is conducted on the circuit board through circulation flow of cooling media, heat dissipation is uniform, and the heat dissipation effect is better.

    本发明公开一种带有电路板散热结构的无人机,分隔板将无人机本体的腔室分隔为上腔室和下腔室,电路板散热部件,截面呈回型状,且一侧边开口,其顶板底部和底板顶部设置有相互平行的热传导板,并且顶板和底板内具有相互连通的循环通道,电路板设置在两个的热传导板之间,换热其进液端与循环通道的出口端通过导管连通,储液箱设置在下腔室内,其内部具有冷却介质,并且进液端与换热器的排液端通过导管连通,抽液泵进液端与储液箱的排液端通过导管连通,其排液端与通过导管与循环通道的进口端连通,相对于传统的置散热风扇的散热结构,将电路板包围并且通过冷却介质的循环流动对电路板进行全面散热,散热均匀并且散热效果更好。
