Heat exchanger and producing method thereof

Abstract

A heat exchanger and a production method thereof are disclosed. A through hole (17) is formed in a second header member (17) of a first refrigerant header tank (14) of segmentation type. A protrusion (20a) of a first connector (20) for pipe connection is deformed by being inserted into the through hole (17b) and thus tacked by engagement. Under this condition, the first header member (16) is fitted and tacked on the second header member (17) so that the first connector (20), the second head member (17) and the first head member (16) are integrally brazed and coupled. By doing so, the first connector (20) can be properly coupled to the first refrigerant header tank (14). Further, the first connector (20) can be tacked by engagement before the first refrigerant header tank (14) assumes a cylindrical shape, and therefore the workability of tacking the first connector (20) is improved.

Dependencies are inferred from the claim text.
