Definitions

  • the present invention relates to a heat exchanger for use in an air conditioner for a vehicle.
  • the present invention relates to the heat exchanger, e.g., a subcool type condenser or the like, which has a function as a receiver and has an interior member including a filter and a desiccant.
  • a heat exchanger for example, a subcool type condenser that has the function as a conventional receiver, is known in the art.
  • a subcool type condenser accommodates an interior member including at least a filter, particularly a filter and a desiccant in a condenser.
  • the interior member such as a packed-desiccant having a cylindrical shape, is pushed into a receiver or the interior member, such as a desiccant integrally formed with a filter that is packed by a netcasing, is pushed into the condenser.
  • Such an interior member may be accommodated to be able to be exchanged, and the condenser maintains the interior member in its fixed position, as necessary.
  • the condenser When an interior member is accommodated, in case of it being deformed by a heat of refrigerant, the condenser provides the interior member with a certain amount of strength.
  • a subcool type condenser 1 is also known in the art.
  • a subcool type condenser 1 comprises a second header 2 and a first header 3 which are vertically arranged in parallel with each other, and a plurality of heat exchanger tubes 4 which extend in parallel with each other, communicating between both the headers 2 and 3.
  • Pluralities of corrugated fins 5 are provided between heat exchanger tubes 4 and on their outer layers.
  • the second header 2 has an inlet pipe 6 for introducing refrigerant and an outlet pipe 7 for discharging refrigerant at the lower portion in a vertical direction.
  • a partition board 8 is provided within the second header 2.
  • the partition board 8 divides the inside of the second header 2 into an upper compartment (an upper header section 2a) and a lower compartment (a lower header section 2b).
  • This partition board 8 also divides the area in which the plurality of heat exchange tubes 4 are located, into a refrigerant condensing core 9 and a subcool core 10.
  • the condensing core 9 condenses the refrigerant introduced into the condenser 1 and the subcool core 10 supercools the condensed refrigerant from refrigerant condensing core 9.
  • the partition board 8 provided in integrally formed the second header 2 divides the entire core of the condenser 1 into a refrigerant condensing core 9 and a subcool core 10.
  • the refrigerant introduced through the inlet pipe 6 into the second header 2 passes through the heat exchange tubes 4 of the refrigerant condensing core 9 which constitute one path route and flows into the first header 3. Subsequently, after the refrigerant flows downwardly within the first header 3, the refrigerant is directly introduced into the inlet of the subcool core 10. Moreover, the refrigerant passes through each heat exchange tube 4 of the subcool core 10, and flows out through the outlet pipe 7.
  • the refrigerant condensing core 9 may consist of two or more path routes.
  • At least the lower section 3b of the first header 3 which serves as an inlet to the subcool core 10 constitutes a refrigerant liquid storage area 11.
  • refrigerant from the refrigerant condensing core 9, namely refrigerant coming from the upper section 3a of the first header 3 is stored in this liquid storage area 11. Subsequently, the refrigerant flows into each heat exchange tube 4 of the subcool core 10.
  • an interior member 15 is accommodated within the first header 3.
  • the interior member 15 comprises a liquid-permeable casing 14.
  • a desiccant 13 is disposed in casing 14.
  • the casing 14 has a function of holding a desiccant 13 and a function as a filter.
  • the interior member 15 is accommodated in the first header 3 so as to be exchangeable with a cover 16.
  • Interior member 15 has a connecting step 15a. When interior member 15 is inserted from an upper side of the first header 3, connecting step 15a abuts to a support board 17 formed within first header 3, such that interior member 15 is fixed.
  • an interior member 19 has a connecting step 19a.
  • connecting step 19a abuts to a support board 20 formed within first header 3, such that interior member 19 is fixed.
  • interior members 15 and 19 if a high atmospheric temperature or a high refrigerant temperature influences interior members 15 and 19, interior members 15 and 19 may be deformed (e.g., interior members 15 and 19 may contract in a vertical direction). Therefore, a space may be created between each connecting step 15a and 19a and each support board 17 and 20, respectively, and such space may cause vibration because interior members 15 and 19 come into collision with support boards 17 and 20. As a result, noise may occur, or interior members 15 and 19 may be damaged. Moreover, connecting portions between connecting steps 15a and 19a and support boards 17 and 20 may prevent the refrigerant from flowing from condensing core 9 to subcool core 10.
  • the refrigerant may shortcut the connecting portion, and a foreign body other material (e.g., pieces of a desiccant) may not be caught by interior members 15 and 19. Therefore, such foreign body may circulate into a refrigerant cycle with the heat exchange medium, and components in the refrigerant cycle may be damaged.
  • interior members 15 and 19 may not remove the water in the heat exchange medium. Therefore, such a subcool type condenser may not perform properly.
  • a technical advantage of the present invention is that a connecting portion between an interior member and a header of the heat exchanger may be sealed.
  • a heat exchanger comprising:
  • the heat exchanger may have two headers communicated with each other by a plurality of heat exchanger tubes extending between the headers in parallel with each other.
  • the refrigerant route is formed from the header and the tubes.
  • the heat exchanger may be a refrigerant condenser and further comprises a refrigerant condensing core and a subcool core.
  • the refrigerant condensing core condenses the heat exchange medium.
  • the subcool core supercools the heat exchange medium condensed by the refrigerant condensing core.
  • the refrigerant condensing core and the subcool core are divided each other.
  • a first header namely one of said two headers which is located on the subcool core inlet side, its section serving at least as an inlet to the subcool core constitutes a refrigerant liquid storage area.
  • the interior member may be a liquid-permeable casing that is filled with a desiccant. Also, all or a part of the liquid-permeable casing may be formed from filter.
  • the elastic seal may be one of an o-ring or felt or a bellows.
  • a substantial part of a heat exchanger of the present invention according to a first embodiment is described.

  • Interior member 21 includes casing 22, and a part of casing 22 is formed of a net and desiccant 23 disposed in casing 22.
  • casing 22 has the function of holding desiccant 23 and as a filter.
  • Casing 22 has a connecting step 21a, a small diameter portion 21b, and a large diameter portion 21c.
  • Connecting step 21a abuts to a support board 17.
  • Small diameter portion 21b is disposed into a lower section 3b of subcool type condenser 1.
  • a large diameter portion 21c is disposed into an upper section 3a of subcool type condenser 1.
  • a small diameter portion 21b penetrates an opening 17a formed through support board 17.
  • a part of casing 22, namely, a small diameter portion 21b is formed of a net including the function of a filter.
  • a bellows 24 for sealing between connecting step 21a and support board 17 is formed integrally with connecting step 21a. Alternatively, bellows 24 may be formed integrally with support board 17.
  • Interior member 21 includes an o-ring 25 as an elastic sealing member instead of bellows 24 of Figs. 6 and 7.
  • interior member 21 may include felt 25 as an elastic sealing member instead of o-ring 25.
  • the structure of the heat exchanger other than the elastic sealing members in this embodiment of the present invention is substantially the same as that of subcool type condenser 1 depicted in Figs. 6 and 7.
  • FIG. 9 and 10 an area around a support member 20 of a subcool type condenser 1 and a substantial part of an interior member 31 are described, respectively, according to a second embodiment of the present invention.
  • the structure of the heat exchanger is substantially the same as subcool type condenser 1 depicted in Fig. 4 and 5 except that interior member 31 is inserted from a lower side of the first header 3 into first header 3.
  • Interior member 31 includes a casing 32 formed entirely of a net and a desiccant 33 disposed in casing 32.
