The invention discloses a battery assembly heat dissipation system of an electric aircraft, which comprises a heat dissipation channel, a heat dissipation fan, a plurality of battery cells and at least one spacing structure, the plurality of battery cells are arranged in the heat dissipation channel side by side, and the spacing structure is formed by a plurality of spacing plate arrays with different thicknesses. The plurality of spacing plates are arranged between the adjacent battery cells, a gap communicated with the heat dissipation channel is formed between every two adjacent battery cells, and due to the thickness difference of the spacing plates, the thicknesses of the gaps between every two adjacent battery cells are different. The thickness of the gap between the adjacent battery cells is determined by the thickness of the spacing plate, so that the air flow is increased by properly increasing the thickness of the gap at the position of the gap with lower flow velocity of an air flow field, namely, the thickness of the gap can be increased at the position of the lower flow velocity of the air flow field, the air flow field is more uniform, and the problems that the air flow field is not uniform and the flow rate is low in the prior art are solved. And a relatively large temperature difference exists between the battery cells.
本发明公开了一种电动航空器的电池组件散热系统,包括散热通道、散热风扇、多个电芯以及至少一个间隔结构,所述多个电芯并排设置于所述散热通道的内部,所述间隔结构由多个不同厚度的间隔板阵列而成,所述多个间隔板设置于相邻的电芯之间,相邻两个电芯之间具有与所述散热通道贯通的间隙,由于每一个间隔板的厚度差异,相邻两个电芯之间的间隙的厚度不同。由于间隔板的厚度决定相邻电芯间的间隙的厚度,使空气流场流速较低的间隙的位置通过适当扩大其间隙厚度来增加空气流量,即可以在空气流速较低的位置增加间隙的厚度,使空气流场更为均匀,解决目前技术存在的空气流场不均匀,电芯之间存在较大的温差的技术问题。
