A header-tank assembly

Abstract

The header-tank assembly includes a tank, a header a sealing element. The tank includes foot portions configured on at least one pair of opposite sides thereof. The header includes tabs configured on at least one pair of opposite sides. The tabs are crimped along fold lines configured thereon to receive the respective foot portions of the tank and configure connection between the header and the tank. The sealing element is disposed between the foot portions of the tank and the header. A notch is configured on an outside wall of each tab, wherein the notch extends along the fold line to facilitate crimping of the tabs over the respective foot portions and is visible after crimping operation.

1 . A header-tank assembly comprising:
 a tank comprising foot portions configured on at least one pair of opposite sides thereof;   a header comprising tabs configured on at least one pair of opposite sides thereof, the tabs adapted to be crimped along fold lines configured thereon to receive the respective foot portions of the tank and configure connection between the header and the tank;   a sealing element disposed between the foot portions of the tank and the header,   wherein a notch is configured on an outside wall of each tab, the notch extends along the fold line to facilitate crimping of the tabs over the respective foot portions.   
     
     
         2 . The header-tank assembly as claimed in  claim 1 , wherein at least one tab is configured on each side of at least one pair of opposite sides of the header. 
     
     
         3 . The header-tank assembly as claimed in  claim 1 , wherein the tabs configured on each side of at least one pair of opposite sides of the header are spaced apart from each other. 
     
     
         4 . The header-tank assembly as claimed in  claim 1 , wherein the tabs are adapted to fold along the respective fold lines and the notches extending along top edges of the foot portions of the tank received in the respective header to define the crimped configuration of the tabs of the headers. 
     
     
         5 . The header-tank assembly as claimed in  claim 4 , wherein the tabs in the crimped configuration thereof are adapted to receive the respective foot portions of the tanks such that a first portion and a second portion of the tabs connected along the notch abut against edges of the foot portions of the tank. 
     
     
         6 . The header-tank assembly as claimed in  claim 1 , wherein thickness of each tab along the notch is reduced by 10-35 percent as compared to the rest of the tab. 
     
     
         7 . A heat exchanger comprising a pair of spaced apart header-tank assembly and connected by a plurality of heat exchanger elements, wherein a first header-tank assembly is adapted to facilitate distribution of heat exchange fluid to the heat exchanger elements, whereas a second header-tank assembly disposed opposite to and spaced away from the first header-tank assembly is adapted to facilitate collection of heat exchange fluid from the heat exchanger elements, at least one of the header-tank assembly of the pair of header-tank assembly is according to  claim 1 .
