The utility model relates to a solar energy power generation flow box that uses foreign currency specifically is a photovoltaic power plant heatstroke prevention collection flow box, has solved current collection flow box and has had the easy ageing problem that causes life to shorten. Photovoltaic power plant heatstroke prevention collection flow box, including the box, the bottom of box is provided with the bottom plate that white was painted to the lower surface, opens the shutter that has the blade slant to have a down dip on the wall of the box left and right sides, and the window department of shutter is provided with dustproof yarn, and the lateral wall and the roof surface of box all are provided with aluminium membrane reflector layer. The utility model has the advantages of reasonable design reliably, weakened sunshine and installation base surface to converging flow box's heat radiation, improved the ventilative heat dispersion who converges in the flow box moreover, guaranteed incasement electric elements's normal intensification simultaneously, reduced the line impedance loss, and then the extension converges the life of in flow box device, have simple structure, processing is convenient and advantage with low costs.
