| 摘要 |
The invention relates to a thin wall header with a variable cross-section for solar absorption panels, manufactured in nickel-based superalloy and formed by a main thin wall body (18) and by a plurality of nozzles (16,21). The header (10) is connected to a series of junction nozzles (16) wherein respective solar absorption tubes (14) are connected, and at least one inlet or outlet nozzle (21) wherein at least a fed tube is connected. The body (18) can have a spindle shape or can be formed by two frustoconical sections joined by the larger base, and can further have a central cylindrical section at the height of the inlet or outlet nozzles (21). It is applicable in the collection of fluids at high temperature, especially in solar panels.
