Solar array

摘要

The system (1) has a solar heat collector (2) comprising a collector tube with a cladding tube (6) that is engaged with a register (5). An inner chamber connected with atmosphere is formed between the cladding tube and the register that is connected with an inlet port (17) and an outlet port (19) through which the register supplies a heat carrier. The register partially consists of structural steel, and a protective device is formed such that formation of condensed water on an outer surface of the register is prohibited. The outer surface of the register turns towards the heat carrier. The structural steel material is selected from pressure resistant steel material. The cladding tube is designed as a vacuum tube.
