本发明提出了一种氢燃料电堆风洞式辅助散热装置,包括集风罩、风洞件、若干散热格栅、移动机构和旋转清洗机构,集风罩内设有进风通道;风洞件呈圆筒体,风洞件的一端与进风通道的出风端相连通;若干散热格栅均设置于风洞件的内壁上,且沿风洞件的轴向延伸方向设置,散热格栅内设有流体通道,氢燃料电堆的冷却液流动在流体通道中;该装置的散热格栅沿风洞件的轴向方向设置在风洞件的内壁上,在引风面上受到的风阻较小,进而不会影响到车辆行驶中的受力问题,有效的保证了车辆驾驶的安全性,并且节能环保,同时,该装置结构集成度高,占用空间小,满足车辆上有限的空间、轻量化和节约电能的要求。

    The invention provides a hydrogen fuel stack wind tunnel type auxiliary heat dissipation device which comprises a wind collection cover, a wind tunnel piece, a plurality of heat dissipation grids, a moving mechanism and a rotary cleaning mechanism, and a wind inlet channel is arranged in the wind collection cover; one end of the wind tunnel piece is communicated with the air outlet end of the air inlet channel; the plurality of heat dissipation grids are arranged on the inner wall of the wind tunnel part and are arranged in the axial extension direction of the wind tunnel part, fluid channels are formed in the heat dissipation grids, and cooling liquid of the hydrogen fuel electric pile flows in the fluid channels; the heat dissipation grating of the device is arranged on the inner wall of the wind tunnel piece in the axial direction of the wind tunnel piece, wind resistance on the air inducing face is small, then the stress problem in the vehicle running process cannot be affected, the vehicle driving safety is effectively guaranteed, energy saving and environment protection are achieved, and meanwhile the device is high in structural integration degree, small in occupied space and convenient to use. And the requirements of limited space, light weight and electric energy saving on the vehicle are met.
