Definitions

  • the present invention generally relates to a heat exchanger, more particularly, to a header-tank assembly of a heat exchanger provided with a groove-protrusion setup to retain the tank within the header while assembling the tank with the header of the heat exchanger.
  • heat exchanger are provided with a pair of tanks to enable introduction or reception of fluid to or from the heat exchanger.
  • the heat exchanger may include a core provided with a pair of headers at both side of the core.
  • the pair of headers is adapted to be coupled with the pair of tanks, thereby enabling the fluid circulation to the core of the heat exchanger.
  • a gasket is introduced to provide proper sealing between the pair of tanks and the pair of headers.
  • the pair of headers is brazed with the core and it is provided with any connecting means to couple it with the pair of tanks.
  • the connecting means may be tabs formed on the periphery of the pair of headers and adapted to be crimped on the tanks to enable connection between the pair of tanks and the pair of headers.
  • the gasket is provided on the pair of headers, followed by placing the pair of tanks on the respective headers of the core.
  • the assembly is moved to a machine in which the tabs formed on the headers are crimped/bent on the foot portion of the respective tanks.
  • the pair of tanks In order to enable optimal crimping between the pair of tanks and respective headers, the pair of tanks have to lie flat on the gasket provided on the respective headers without any inclination of the tank.
  • a header and tank assembly is known from US 2002/144808 A1 .
  • the pair of tanks may pop from the respective header while assembling the tank on the respective header. Further, the pair of tanks may not lie flat on the gasket provided on the respective header, which may lead to improper connection between the pair of tanks and respective headers. Further, any inclination of the tank with respect to the respective header prevents the tabs formed on the header from being crimped on the tanks, and it may lead to damaging the gasket e.g., by pinching. In case the pair of tanks having centre of gravity distant from symmetry plane of the tanks, the pair of tanks may experience topping out of tank on one side from the respective header and results in falling out of the tank from the respective header.
  • 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. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.
  • an embodiment of the invention herein provides a header-tank assembly according to claim 1.
  • the protrusion is formed on the outer wall of the foot portion of the tank on a side opposite to the first side of the tank, and the groove is formed on inner wall of the header, complementary to the protrusion.

  • the protrusion is formed throughout any one of the outer wall of the foot portion of the tank, and the inner wall of the header.
  • the groove is formed throughout any one of the outer wall of the foot portion of the tank, and the inner wall of the header.
  • the protrusion comprises a slope adapted to slide into the groove when the tank is positioned on the header.
  • a gasket disposed on a gasket recess formed on the header is adapted to provide sealing between the header and the tank when the tank is positioned on the header.
  • the heat exchanger includes a heat exchanger core fluidically connected to the header.
  • the conduit is fluidically connected to the header to enable fluid flow to the heat exchanger core.
  • the present invention relates to a heat exchanger provided with a pair of tanks coupled with a core of the heat exchanger.
  • the heat exchanger may include a pair of headers corresponding to the pair of tanks.
  • the pair of tanks is adapted to be coupled with the respective headers of the heat exchanger.
  • the pair of headers and the pair of tanks are collectively referred to as a header-tank assembly.
  • the heat exchanger explained in the present document is described with one header and one tank.
  • the present document is explained with a header and a tank amongst the pair of header and tank assemblies, the same features can be applied to other header and tank amongst the pair of header and tank assemblies.
  • the heat exchanger is provided with a groove-protrusion configuration to retain the tank on the header, while assembling the tank on the header.
  • the groove is complementary to the protrusion formed in the heat exchanger, and adapted to be coupled with each other, thereby providing a retention force between the tank and the header while assembling the tank on the header of the heat exchanger. Further, detailed location and geometry of the groove-protrusion configuration are explained with forthcoming description with figures.
  • FIGS. 1 and 2 illustrate schematic views of a heat exchanger 100, in accordance with an embodiment of the present invention.

  • the symmetric plane of the tank 104 is defined on a point on which both sides of the tank 104 have equal mass. In such cases, the tank 104 may pop-out from the header 102 at one side, while crimping the tank 104 on the header 102.
  • the conduit 112 is formed on a first side 104A of the tank 104, so the centre of gravity is moved out of the symmetric plane of the tank, thereby the tank 104 may not lie flat on the header 102 and there may be an inclination between the tank 104 and the header 102. Such inclination may lead to toppling of the tank 104 while assembling the tank 104 on the header 102 and to damaging of the gasket as pinching, provided in the header 102.
