Abstract
Improper assembly and/or dissociation due to improper handling of a tank 10 to header plate 14 joint in a heat exchanger is avoided through the use of a retaining strip 50 having fingers 54 receivable in slots 36 in an upstanding flange 26 surrounding a sealing surface 28 on the header plate 14. The fingers 54 are provided with hook-like formations 60, 62, 64 which lodge behind a surface 44 of the flange 26.
Claims15
A heat exchanger comprising:
- a header plate having a peripheral seal receiving groove;
- a resilient seal disposed in said groove;
- an upstanding flange surrounding said groove;
- an aligned row of apertures in said flange above the bottom of said groove;
- a tank having a peripheral outwardly directed flange located in said groove and having a first surface sealed against and compressing said seal and an opposed surface nominally aligned with said row of apertures;
- and
- a tank flange retainer including an elongated strip with a plurality of hook-like formations, said strip being disposed on the side of said upstanding flange opposite said groove with said formations extending through said apertures and lodged against said upstanding flange oppositely of said strip in overlying relation to said tank flange.

A heat exchanger comprising:
- a header plate having a peripheral seal receiving surface;
- a resilient seal engaging said surface;
- an upstanding flange surrounding said surface;
- an aligned row of apertures in said flange above said surface;
- a tank having a peripheral outwardly directed flange disposed within said upstanding flange and having a first surface sealed against and compressing said seal against said header plate surface and an opposed surface nominally aligned with said row of apertures;
- and
- a tank flange retainer including an elongated strip with a plurality of fingers terminating in hook-like noses disposed on the side of said upstanding flange opposite said seal receiving surface with said fingers extending through said apertures such that said noses lodge against said upstanding flange oppositely of said strip in overlying relation to said tank flange and in engagement with said opposed surface.

- a resilient seal engaging said surface;
- an upstanding flange surrounding said surface;
- an aligned row of apertures in said flange above the bottom of said groove;
- a tank having a peripheral outwardly directed flange disposed within said upstanding flange and having a first surface sealed against and compressing said seal and an opposed surface nominally aligned with said row of apertures;
- a tank flange retainer including an elongated, semi-rigid strip with a plurality of fingers, said strip being disposed on the side of said upstanding flange opposite said seal receiving surface with said fingers extending through said apertures and lodged against said upstanding flange oppositely of said strip in overlying relation to said tank flange to prevent removal of said strip;
- and
- means on said strip for preventing any of said fingers from said lodging against said upstanding flange unless all of said fingers lodge against said upstanding flange.
