Header for high pressure heat exchanger

摘要

A header (36,38) for high pressure heat exchanger includes a header body (42) with a plurality of supporting members (42a) longitudinally formed and a cover plate (44) combined and closely contacting the supporting members (42a) such that a space is formed between the header body (42) and the cover plate (44), in which inserting grooves (42c) to insert the ends of tubes thereinto are formed at the supporting members, and tube inserting holes (44a) to insert the tubes are formed at the cover plate (44). Accordingly, it is easy to assemble and braze the header and tubes, and the cross section of the header is reduced and pressure proof is improved as well.
