Binding Structure between Tank and Header of Automotive Heater Core

Abstract

This invention involves a binding structure between tank and header of an automotive heater core, which belongs to the field of auto parts technology. Said structure includes the upper tank ( 3 ), the bottom tank ( 8 ) and the header ( 4 ). Characteristics of said structure are that there are clinching tabs ( 4.1 ) around the headers connecting to the upper tank ( 3 ) and to the bottom tank ( 8 ). Said clinching tabs ( 4.1 ) clamp to the edges of the upper tank ( 3 ) and the bottom tank ( 8 ). The clamping of clinching tabs to the edges of the tanks structurally ensures the mechanical strength of the binding between the header to the upper tank and to the bottom tank. It ensures a good brazing and firm binding between the tanks and the header.

1 . A binding structure between tank and header of automotive heater core comprising a upper tank, a bottom tank and a header, the header has clinching tabs around the top border and bottom border thereof for connecting the upper tank and the bottom tank by clamping to the edges of the upper tank and the bottom tank.
