Definitions

  • the present invention relates to a heat exchanger, and, more specifically, to a heat exchanger suitable as a radiator and the like used in a refrigeration cycle using carbon dioxide as its refrigerant.
  • Carbon dioxide has been paid attention to as a refrigerant to be substituted for a fleon group refrigerant which has been used in a refrigeration cycle.
  • various alterations are required also with respect to the structure of a heat exchanger, as compared with a case where a fleon group refrigerant has been used.
  • a cross-flow type heat exchanger because air for cooling having a substantially constant temperature is introduced over the entire area of the radiation route, in a case where this cross-flow type heat exchanger is used as a gas cooler (a radiator) and the like of a refrigeration cycle for refrigerant of carbon dioxide, the temperature difference between the refrigerant and the air for cooling becomes great at the entrance side of the route and becomes small at the exit side of the route, and a high efficiency for heat exchange cannot be obtained as a whole. Accordingly, as described above, by using a so-called counter-flow type heat exchanger, the temperature difference between air for cooling and refrigerant can be ensured sufficiently great over the entire area of the route, and the efficiency for heat exchange can be increased.
  • the refrigerant of carbon dioxide is to be used at a high pressure from the property thereof, a high pressure resistance is required to a header and the like of the heat exchanger.
  • a header structure satisfying such a high pressure-resistance performance it is known that a structure of a header formed integrally by extrusion or drawing is effective, and in particular, it is known that, even in a case where twin fluid (refrigerant) passages are formed in a single header, while a high pressure-resistance performance can be ensured, the processing performance for production also can be improved (for example, JP-A-11-226685).
  • this JP-A-11-226685 only discloses a structure wherein merely parallel refrigerant flows are simultaneously formed in a direction across the flow direction of outside air for heat exchange.
  • the above-described JP-A-2004-77079 discloses a structure of counter flow, it only shows a structure wherein the refrigerant flows merely at a snaking condition in the heat exchanger core portions which are disposed adjacent to each other relative to the flow direction of outside air for heat exchange, and therefore, it is difficult to say that this JP-A-2004-77079 shows an optimum formation of refrigerant flow on a viewpoint of heat exchange performance.
  • the headers of one heat exchanger core portion are formed separately from the headers of the other heat exchanger core portion disposed adjacent to the above-described one heat exchanger core portion, both headers are communicated by an exterior pipe, and therefore, in such a structure, not only a high pressure-resistance performance as in JP-A-11-226685 cannot be expected, but also the assembling work of the entire heat exchanger becomes complicated. Further, because the respective headers are made independently, dispersion on processing may occur in the dimension and pitch of the tube insertion holes.
  • a heat exchanger has at least one header, the whole of which is integrally formed by extrusion or drawing and in which a plurality of fluid passages are provided in parallel to each other and parted from each other, and a plurality of tubes which are connected to the header so that an end of each of which communicates with each of the fluid passages, and is characterized in that a first partition is provided in a first fluid passage which is one of fluid passages adjacent to each other in the header, a second partition is provided in a second fluid passage which is the other of the fluid passages adjacent to each other at a position different from a position of the first partition in a fluid passage extending direction, and a communication path is provided to a partition wall parting the first and second passages from each other at a position between the first and second partitions to communicate the first and second passages with each other.
  • first and second partitions are provided to the first and second fluid passages adjacent to each other, respectively, a route structure where fluid can go and return can be employed for each of a first heat exchanger core portion formed by using the first fluid passage and a second heat exchanger core portion formed by using the second fluid passage, and a high heat exchange performance can be achieved as the entire heat exchanger.
  • first partition and the second partition are disposed so as to shift from each other in the fluid passage extending direction, and the communication path is provided to the partition wall between the first and second passages at a position between the first and second partitions, an external communication path becomes unnecessary, and a desirable heat exchanger can be realized by a simple assembling work.
  • a target counter-flow type heat exchanger can be realized easily and surely. Namely, a counte'r-flow type heat exchanger optimum for a refrigeration cycle using fluid of carbon dioxide can be realized.
  • the above-described communication path may be provided by post-processing of the header from outside (for example, by carrying out hole-opening processing or cutting from the outer surface side of the header, and processing a through hole and the like, functioning as the communication path, on the above-described partition wall), and an opening formed on the outer surface of the header by this post-processing may be closed by providing a lid member or welding. Namely, by processing from outside of the header, a desirable communication path can be easily provided.
  • a structure may be employed wherein a pipe reinforcing portion extending up to an inlet pipe for introducing fluid into the header or an outlet pipe for discharging fluid from the header to support the inlet pipe or the outlet pipe is provided integrally with a partition member forming the first or second partition.
  • a structure may be employed wherein a pipe reinforcing portion extending up to an inlet pipe for introducing fluid into the header or an outlet pipe for discharging fluid from the header to support the inlet pipe or the outlet pipe is provided integrally with the above-described lid member.
  • Another heat exchanger has at least one header, the whole of which is integrally formed by extrusion or drawing and in which a plurality of fluid passages are provided in parallel to each other and parted from each other, and a plurality of tubes which are connected to the header so that an end of each of which communicates with each of the fluid passages, and is characterized in that a first partition is provided in a first fluid passage which is one of fluid passages adjacent to each other in the header, a second partition is provided in a second fluid passage which is the other of the fluid passages adjacent to each other at a position different from a position of the first partition in a fluid passage extending direction, and a communication path is processed relative to a partition wall parting the first and second passages from each other at a position between the first and second partitions to communicate the first and second passages with each other, together with processing of a tube insertion hole in the header.
  • first and second partitions are provided to the first and second fluid passages adjacent to each other, respectively, a route structure where fluid can go and return can be employed for each of a first heat exchanger core portion formed by using the first fluid passage and a second heat exchanger core portion formed by using the second fluid passage, and a high heat exchange performance can be achieved as the entire heat exchanger.
  • first partition and the second partition are disposed so as to shift from each other in the fluid passage extending direction, and the communication path is provided to the partition wall between the first and second passages at a position between the first and second partitions, an external communication path becomes unnecessary, and a desirable heat exchanger can be realized by a simple assembling work.
  • a target counter-flow type heat exchanger can be realized easily and surely. Namely, a counter-flow type heat exchanger optimum for a refrigeration cycle using fluid of carbon dioxide can be realized.
  • the above-described communication path may be formed extremely easily by cutting away a part of the partition wall by utilizing the processing of the tube insertion hole of the header.
  • an opening of the header extending from the outer surface of the header to a communication path forming portion of the partition wall is formed in this processing of the tube insertion hole, a portion except the communication path in the opening of the header formed by the processing of the tube insertion hole may be closed by a tube itself inserted into the opening.
