Tank and spout interface for heat exchanger and its manufacturing

摘要

A tank and spout interface of a radiator of a motor vehicle having a tank part having an inner surface, an outer surface, a connecting part, a bottom portion, a first end, a second end, a first outer margin, and a second outer margin. The tank and spout interface has a connection sleeve disposed on the tank part and extending outwardly from the tank part having an inner surface integrally formed with the inner surface of the first outer margin of the tank part and an outer surface integrally formed with the outer surface of the tank part. A first entry riser and a second entry riser are disposed on opposing sides of the inner surface of the connection sleeve and a first internal riser and a second internal riser are disposed on the first outer margin of the tank part.

1. A tank and spout interface of a radiator of a motor vehicle, comprising:
a tank part having an inner surface, an outer surface, a bottom portion, a first end, a second end, a first outer margin, and a second outer margin; a connection sleeve having a central axis, the connection sleeve disposed on the tank part and extending outwardly from the tank part, the connection sleeve having an inner surface integrally formed with an inner surface of the first outer margin of the tank part and an outer surface integrally formed with the outer surface of the tank part; a first entry riser and a second entry riser disposed on opposing sides of the inner surface of the connection sleeve adjacent the first outer margin of the tank part; a first wall riser and a second wall riser disposed on the inner surface of the first outer margin of the tank part, the first wall riser integrally formed with the first entry riser and the second wall riser integrally formed with the second entry riser, the first wall riser and the second wall riser protruding from the inner surface of the tank part and extending towards the bottom portion; a first end riser and a second end riser disposed on the second outer margin of the tank part and a partition disposed intermediate the first end riser and the second end riser, wherein the first entry riser and the second entry riser respectively protrude inwardly in a radial direction of the connection sleeve for narrowing a flow passage of the connection sleeve, and wherein the partition is aligned with the central axis of the connection sleeve and protrudes from the second outer margin beyond the first end riser and the second end riser; and at least three guide risers equidistantly spaced apart from each other and disposed on the first outer margin intermediate the second wall riser and the second end of the tank part, wherein each of the guide risers has a height in a longitudinal direction thereof, the height of each of the guide risers decreasing with an increasing distance from the second wall riser; wherein the longitudinal direction of each of the guide risers is arranged perpendicular to the central axis of the connection sleeve, the central axis of the connection sleeve arranged substantially perpendicular to the first outer margin and the second outer margin and the connection sleeve located at a position on the tank part substantially opposite the bottom portion of the tank part.
