Abstract
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.

A thin wall header with a variable cross-section for solar absorption panels, manufactured in nickel-based superalloy for the distribution and collection of molten nitrate salts or any other fluid at high temperature, formed by a main body, a plurality of junction nozzles distributed throughout the body, connecting it to solar absorption tubes, and at least an inlet or outlet nozzle connecting the body to at least a feed tube, wherein the main body has a variable cross-section, decreasing continuously from a central area with a maximum cross-section until reaching the end sections of the body, the axis of the at least one inlet or outlet nozzle being located in said central area, and
- wherein the body of the header adopts a spindle shape.
