STRUCTURE OF ONE UNIT CAP FOR HEAT CORE

摘要

An integrated cap structure of a heater core is provided to restrict the insertion length of cooling water pipe by preventing the cooling water pipe from being excessively inserted through the bead formed on the end of inward protrusion. An integrated cap structure of a heater core comprises an integrated cap(50) combined to the end part of a header tank(20), a cooling water pipe(P) which is inserted and welded in the integrated cap, an inward protrusion(54) protruding to the inside of the integrated cap on the side of the integrated cap, and a bead(54a) which is formed so that the end of the cooling water pipe is hung at the end part of the inward protrusion.
