Solar steam generation device

The invention provides a solar steam generation device which has the beneficial effects of being good in heat collection effect, stable in performance and durable. The solar steam generation device comprises a header (2) and heat collection tubes (16) connected with the header (2). The header (2) is provided with at least one heat exchange tube (11), the heat exchange tubes (11) enter inner tubes (7) of the corresponding heat collection tubes (16) in sequence, and the steam outlet ends (18) of the heat exchange tubes (11) are located inside or outside the header (2). The inner tubes (7) are provided with heat transfer fins (5), and the cross section of each heat transfer fin (5) is in an arc shape or a W shape. If the cross section of each heat transfer fin (5) is in the arc shape, the outer surfaces of the arc-shaped parts are provided with first grooves (19) and second grooves (20) for installing the heat exchange tubes (11); and if the cross section of each heat transfer fin (5) is in the W shape, the W-shaped parts each comprise two wings and a middle portion, the wings abut against the walls of the inner tubes (7), and the heat exchange tubes (11) are arranged at the middle portions. The parts, located in the header (2), of the heat exchange tubes (11) are provided with heat insulation bodies (12) used for isolating the parts from heat insulation materials (13) with which the header (2) is filled.
