A solar receiver includes a hollow body, which has a longitudinal axis (8.4), a wall (8) surrounding the longitudinal axis (8.4), an opening (9) disposed in the wall (8) for the entry of heat rays, and an end region opposite the opening (9). The wall (8) includes an outer wall (8.1), an inner wall (8.2), and a partition wall (8.3) disposed therebetween. The outer wall (8.1) and the partition wall (8.3) enclose an outer annular space (8.1.1). The inner wall (8.2) and the partition wall (8.3) enclose an inner annular space (8.2.1). The outer annular space (8.1.1) has, in the end region, an inlet (12) for a free-flowing medium. The two annular spaces (8.1.1, 8.2.1) are conductively connected to one another in the region of the opening (9), and the inner annular space (8.2.1) has an outlet (11) for a free-flowing medium in the end region.
