The utility model discloses a plastic roll-forming greenhouse solar heat collecting plate which comprises a heat transfer medium inlet header pipe, a heat transfer medium outlet header pipe and a plurality of hollow pipes, the heat transfer medium inlet header pipe is communicated with an inlet of each hollow pipe through a flow dividing structure, the hollow pipes are arranged in a snakelike loop mode, and the heat transfer medium inlet header pipe is communicated with the heat transfer medium outlet header pipe. And an outlet of each hollow pipe in the plurality of hollow pipes is communicated with the heat transfer medium outlet header pipe through a flow collecting structure. By means of the mode, the plate-type solar heat exchanger is formed in a one-time blowing mode, high in solar radiation absorptivity, low in emissivity, high in mechanical strength, good in heat transfer medium pressure bearing performance, large in heat exchange area, small in heat exchange temperature difference and low in manufact
