Definitions

  • the present invention relates to a header-tank assembly for a heat exchanger.
  • a heat exchanger generally includes a pair of spaced apart headers connected to two distant and opposite end portions of a heat exchanger core that is received inside a housing. Specifically, each of the spaced apart headers is configured with slots for receiving end portions of heat exchange tubes that along with the fins configure the heat exchanger core. Further, the pair of spaced apart headers, hereinafter referred to as headers are also connected to the end portions of the housing either by welding or brazing or any other joining process.
  • the heat exchanger further includes a pair of heat exchanger tanks, hereinafter referred to as tanks, wherein each tank is joined to the corresponding header for configuring a sealed connection between the headers and the corresponding tanks, thereby configuring a header-tank assembly.
  • the headers are connected to the respective tanks by crimping.
  • the tank receives first heat exchanging fluid, often pressurized heat exchanging fluid from a first inlet, the heat exchanging fluid traverses through the heat exchange tubes and is received in the tank.
  • the tank delivers out the first heat exchange fluid through a first outlet.
  • the tanks are connected to the headers by crimping.
  • the tanks in conjunction with the corresponding headers facilitate distribution of first heat exchange fluid to and collection of first heat exchange fluid from the heat exchange core.
  • the crimping between the headers and the respective tanks is used for configuring header tank assembly for different heat exchangers such as for example, Water charge Air-cooler, radiator, condenser and evaporator.
  • the housing receives second heat exchange media, for example, coolant therein and around the heat exchange tubes through at least one second inlet.
  • the second heat exchange media or coolant is delivered out of the housing through at least one second outlet after the coolant has extracted heat from the first heat exchange fluid flowing through the heat exchange tubes.
  • the headers of the header-tank assembly are provided with tabs that fold along fold lines for facilitating crimping of the tabs of the headers over respective foot portions of the tanks with sealing elements disposed between the headers and the respective foot portions of the tanks.
  • the crimping between the headers and the corresponding tanks is required to be secure in order to configure leak-proof connection between the headers and the corresponding tanks.
  • the headers are formed of aluminum. In case the tabs of the headers are thick sectioned, comparative more crimping force is required for crimping the tabs over the respective foot portions of the tanks as compared to when the tabs are thin sectioned.
  • the higher crimping forces may damage the tabs or the crimping tool used for crimping the tabs over the respective foot portions of the tank.
  • the higher crimping forces may also damage the tanks, particularly, in case the tanks are of plastic material. Due to crimping of the tabs over the respective foot portions, cracks and defects may be formed over the tabs, however, these cracks and defects may go un-noticed and aggravate over time resulting in mechanical failures, thereby reducing reliability and service life of the heat exchanger. Examples of such heat exchangers are disclosed in US2002/134529 A or

  • header-tank assembly with header that not only prevents formation of cracks or defects resulting due to crimping of tabs of the header over foot portion of the respective tank but also ensures quick detection of the cracks or defects just by visual inspection, in case the cracks or defects are formed.
  • An object of the present invention is to provide a header-tank assembly with a header that obviates drawbacks associated with conventional headers that do not have any provision for weakening tabs along fold lines to facilitate crimping of the headers on respective tanks and as such the tabs are prone to damage, cracks and defects due to being subjected to high crimping forces during crimping.
  • Another object of the present invention is to provide a header-tank assembly with a header of such configuration that requires comparatively less force for crimping of tabs configured on the header over foot portions of respective tank.
  • object of the present invention is to provide a header-tank assembly with a header of such configuration that substantially reduces forces required for crimping tabs configured on the headers over foot portion of respective tanks, thereby preventing damage to crimping tool used for crimping and extending service life of the crimping tool.

  • Yet another object of the present invention is to provide a header-tank assembly with a header of such configuration that facilitates quick and easy detection of cracks or defects formed on the header just by visual inspection, in case any cracks or defects are formed.
  • some elements or parameters may be indexed, such as a first element and a second element.
  • this indexation is only meant to differentiate and name elements which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention.
