Definitions

  • the present invention relates to a receiver-drier for storing the refrigerant used in an air conditioning device of a vehicle and the like.
  • the air conditioning device mounted on a vehicle and the like is equipped with a receiver-drier that stores the refrigerant compressed by a compressor and liquidized by a condenser, and removes the moisture within the refrigerant.
  • the receiver-drier is formed of a cylindrical body, a refrigerant entrance through which the refrigerant enters the body, and a refrigerant exit.
  • the entrance and the exit of the refrigerant are positioned in the opposite sides in the axial direction of the body, and a drying chamber filled with a drying agent is equipped between the entrance and the exit.
  • the receiver-drier body comprises a cylindrical shape with one end being opened, formed of aluminum alloy so as to reduce the weight of the member.
  • the aluminum alloy has advantageous plasticity and fluidity, so the cylindrical body and a pipe that penetrates through the center portion of the body can be formed together integrally by forging.
  • Japanese Laid-Open Patent Publication No. 5-305381 discloses a method for forming a double walled cylinder having one closed end by forging an aluminum alloy material.
  • the lid member is made of the same aluminum alloy material as the body, and the lid is fixed to the body by MIG welding means and the like.
  • the pipe, the plug and the like that are connected to the body are made of copper alloy material, so these members are joined to the body using for example a mechanical bonding means or a brazing means.
  • the present invention provides a receiver-drier applying an improved bonding means for fixing the pipe etc. onto the body.
  • the receiver-drier comprises as basic means a double wall cylinder body with a bottom and having a pipe member mounted to the center portion thereof, a pair of cap members penetrated by the pipe member and positioned inside said body, a drying agent filled to the space between the pair of cap members, and a lid member that covers the opening portion of said body.
  • the present receiver-drier further comprises a body made of aluminum alloy which is forged integrally with a bottom member including a hole that communicates to said pipe member, a pipe inserted to the hole formed to the bottom member of the body and joined thereto by in-furnace brazing, and a coil spring positioned between the lid member and one of the cap members.
  • the receiver-drier can be equipped with a body made of aluminum alloy which is forged integrally with a bottom member including a hole that communicates to the pipe member, a pipe inserted to a first hole formed to the bottom member of the body and bonded thereto by in-furnace brazing, a plug screwed onto a second hole either formed to the bottom member of the body or to the body, and a coil spring mounted between the lid member and one of the cap members.
