Definitions

  • the present invention is generally relates to a heat exchanger, more particularly to a heat exchanger provided with a connector assembly for connecting a receiver drier to the heat exchanger.
  • a heat exchanger particularly a condenser
  • HVAC Heating Ventilation Air-conditioning system
  • a receiver drier may be connected downstream of the condenser to, inter alia, remove moisture content from the refrigerant.
  • the receiver drier can act as a refrigerant reservoir to the HVAC system.
  • the receiver drier is a bottle having a filter to remove the unwanted content from the refrigerant. Normally, the receiver drier is connected to the condenser through a socket provided on the condenser.
  • the socket is defined on a core of the condenser and perpendicularly protruding from the core of the condenser. Further, the receiver drier may be perpendicularly coupled to the socket with respect to the general direction of the socket's protrusion.
  • Fig. 1 shows a condenser 100 connected with a receiver drier 104 in a conventional connection. As explained above, the socket 106 is perpendicularly protruded out from the core 102 of the condenser 100.
  • the receiver drier 104 is connected to a lateral side of the socket 106.
  • the receiver drier 104 may include a connecting part 108 defined on the same axis as the longitudinal axis of the receiver drier 104.
  • the connecting part 108 may be fluidically connected to channels provided in the socket 106 in such a way that the connecting part 108 is perpendicular to the general axis of protrusion of the socket 106.
  • the receiver drier 104 occupies significant amount of space on the core 102 of the condenser 100. Therefore, it is cumbersome to accommodate the receiver drier 104 on the core 102 of the condenser 100.
  • internal volume of the receiver drier 104 can be reduced, so that the receiver drier 104 can be easily assembled on the core 102 of the condenser 100 without overly protruding over or beyond the outline of the core.
  • such technique may reduce the performance of the receiver drier 104, since less internal volume of the receiver drier 104 may lead to reception and filtration of less amount of the refrigerant flowing from the condenser 100.
  • other conventional methods to connect the receiver drier to the condenser without affecting performance of the receiver drier, may require multiple components, which leads to increase in cost and weight of the condenser.
  • 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.
