Embodiment Construction
[0030] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0031] The present invention is a cavity type solar receiver with shrink tube bundle structure, such as figure 1 with figure 2 As shown, it includes the outer wall of the air inlet 1, the shell 2, the glass base 3, the transparent glass 4, the heat absorber 5, the heat absorber support wall 6, the reverse flow support 7, the connection support 8, the support plate 9, and the air inlet 10, air outlet 11, outer wall 12 of air outlet.
[0032] The outer wall 1 of the air inlet is cylindrical, and the outer shell 2 is hollow and frusto-conical. The end of the circular conical section with a small diameter is fixedly connected to the outer wall 1 of the air inlet, and the end of the circular conical section with a large diameter is fixedly connected to the glass bottom bracket 3 , between the shell 2 and the glass bottom support 3, there is a support pl...

The invention discloses a narrowing tube bundle structural-cavity solar receiver, and belongs to the field of solar high-temperature heat utilization. A narrowing tube bundle heat absorber designed according to a light collection rule makes the receiver uniformly receive solar light rays, the difficult problem that energy in an existing receiver is not uniformly distributed is solved, an air channel structure formed by a truncated conical outer shell, cavity sealing glass, and a truncated conical inner cavity enables working media to flow uniformly in the receiver, accordingly energy flow is well matched, heat collection performance is well achieved, the receiver can operate in a disc-type objective lens and large tower-type concentrating solar power with a concentration ratio of 100, large-power heat exchange is achieved in a limited heat exchange space, and the air working media can be heated so that the outlet temperature can reach more than 1000 DEG C. The receiver has the advantages of being compact, efficient and low in flow resistance, and has a significant meaning for improving competitiveness of a solar high-temperature heat utilization system, and making the solar receiver be high-temperature and efficient.
Description
technical field [0001] The invention relates to a cavity-type solar receiver with a shrinking tube bundle structure, belonging to the technical field of high-temperature heat utilization of solar energy. Background technique [0002] With the rapid development of global industrialization, the consumption of traditional energy continues to increase, and problems such as energy shortage and excessive pollutant discharge are increasing day by day. Human beings urgently need to find new energy sources to solve the contradictions in demand. Among renewable energy sources, solar energy is inexhaustible, green and environmentally friendly, so it is of great significance to vigorously develop solar energy resources. In the field of solar thermal utilization, the dish-type and tower-type solar concentrating heat collection systems with high concentration ratio can realize high energy density heat exchange in a small focused space, drive Stirling, Brayton and other efficient power cyc...
