SOLAR HEAT SOURCE SYSTEM

摘要

A solar heat source system comprises a translucent thermal insulation box (1), a reflecting device, a light-concentration device (2), a heat absorption device (3), and a heat storage device (12). The heat absorption device (3) receives solar radiation and at the same time receives reflected and concentrated radiation. Two types of reflecting mirrors (4, 5) whose planes intersect are provided inside the translucent thermal insulation box (1). The reflecting mirrors (4, 5) are planar reflecting mirrors (5) and convex reflecting mirrors (4) arranged according to a certain rule. A reflecting light-concentrating lens is provided outside the translucent thermal insulation box (1). The rule for the arrangement of the convex reflecting mirrors (4) is that the center-to-center distance (L) of two adjacent heat absorption devices (3) is equal to three times the diameter (d) of a convex reflecting mirror (4). The heat storage device (12) outputs a heat storage medium or outputs thermal energy through a multipath heat exchange device (11, 13). The solar heat source system satisfies a demand for usable heat of temperatures higher than that of boiling water, produces excellent results, and affords a high solar heat utilization rate.
