  • the receiver tank attached to the condenser (condenser) is provided to separate the refrigerant condensed by the condenser into gas and liquid and store the excess refrigerant, and is joined to the header tank of the condenser via the refrigerant inflow and outflow paths.
  • a receiver tank is composed of a lower tubular member having a connecting portion for an inflow pipe and an outflow pipe on the side and an insertion port for a desiccant and a filter at the lower end, and an upper tubular member joined to the upper end of the lower tubular member and having an end cap brazed to the upper end (see Patent Document 1 below).
  • the thickness of the upper tubular member is thinner than that of the lower tubular member, and the thickness of the lower tubular member having the connecting portion is made relatively thick, thereby reducing the overall weight while maintaining strength.
  • the upper and lower cylindrical parts which correspond to the tank body, consist of multiple parts, including the end cap, and each part is formed separately and then joined by brazing, resulting in high manufacturing costs.
  • the risk of defective brazing increases, making it difficult to increase the yield.

  • the present invention having such characteristics can reduce the manufacturing cost of the receiver tank, reduce the risk of defective brazing, and increase the yield.

  • the thickness of the second cylindrical portion 1C is gradually increased from the stepped portion 20 toward the opening portion 1D while keeping the inner diameter of the enlarged diameter portion 21 of the second cylindrical portion 1C constant.
  • a relatively large wall thickness is required near the opening 1D in the second cylindrical portion 1C in order to form the female screw portion 22 described above.
  • the strength required for forming the female screw portion 22 is ensured by making the thickness in the vicinity of the opening 1D thicker than the thickness of the first tubular portion 1B.

At this time, heat exchange is performed in the liquid state of the heat medium, and the temperature drops.

Abstract

[Problème] Réduire les coûts de fabrication d'un réservoir de récupération et diminuer le risque de défauts de brasage afin d'améliorer les rendements. [Solution] Un réservoir de récupération est relié par l'intermédiaire d'un circuit d'entrée et d'un circuit de sortie à un réservoir de collecteur auquel des extrémités d'une pluralité de tubes d'échange de chaleur sont reliées, le réservoir de récupération comprenant un corps de réservoir cylindrique à partie supérieure fermée comportant une ouverture sur un côté d'extrémité et une partie surface supérieure disposée en une seule pièce sur l'autre côté d'extrémité. Le corps du réservoir est formé à l'aide d'un moulage par impact et comprend une première section cylindrique s'étendant, à diamètre interne constant, à partir du côté interne de la partie surface supérieure, et une seconde section cylindrique présentant un diamètre interne s'élargissant au moyen d'une section échelonnée par rapport au diamètre interne de la première section cylindrique.
