- This condensed refrigerant is introduced from the condensing section outlet (lb) into the inflow passage (4a) of the block flange (4), passes through the inflow passage (4a), and flows from the receiver tank inlet (3a) through the receiver tank. Introduced in (3).
- the refrigerant flowing into the receiver tank inlet hole (3a) rapidly diffuses over a wide area in the concave step (330) to reduce the flow velocity. It is lowered, passes through the inlet strainer (333), and rises through the filter layer (335). Further, at the time of this ascent, the filter layer (335) functions as a resistance layer against the flow of the refrigerant, so that the refrigerant further lowers the ascent rate further, and the fibers between the non-woven fabrics constituting the filter layer (335). As a result, the local high-velocity flow disappears due to the rectification effect and the drift is prevented. 350 The refrigerant passes through the refrigerant passage hole (353a) in (50) and flows into the tank interior space (310).
- the liquid refrigerant thus introduced into the tank space (310) forms a liquid pool (R) without being disturbed.
- the gas (gas refrigerant) mixed or generated in the liquid refrigerant that rises up the filter layer (335) rises up the filter layer (335).
- the flow velocity drops rapidly and reaches the liquid pool (R)
- it rises in the liquid smoothly breaks bubbles without disturbing the liquid surface, and escapes above the gas-liquid interface to remove gas refrigerant.
- the refrigerant thus introduced into the receiver tank outlet (3b) is introduced into the outlet (4b) of the block flange (4), passes through the outlet (4b), and passes through the supercooling section (2). Introduced within.
- the liquid refrigerant introduced into the subcooling section (2) is supercooled by the outside air while flowing through the subcooling section (2), and then flows out through the subcooling section outlet (2b).
- the liquid refrigerant thus discharged from the heat exchanger with the receiver tank is decompressed and expanded by the expansion valve, then absorbs heat from the outside air in the evaporator, evaporates and returns to the compressor.
- the refrigerant circulates through the refrigeration cycle of the refrigeration system, and a predetermined refrigeration performance is obtained.
- the condensed refrigerant introduced into the receiver tank (3) forms a liquid pool (R) gently at a low speed and is efficiently and smoothly defoamed.
- the stable range of the filling amount can be expanded, and only stable liquid refrigerant can be reliably extracted. Therefore, the liquid refrigerant can be stably supplied to the supercooling section of the heat exchanger, so that the refrigeration cycle can be operated in a stable state, and excellent refrigeration performance can be obtained.
- the receiver tank (3) can be made smaller and smaller, and the performance can be reduced. In addition, refrigerant can be saved.
- one filter layer (335) is formed as a layer, it is not necessary to separately provide a resistance layer, so that the number of parts can be further reduced, the structure can be simplified, and the cost can be reduced. Can be achieved.
- the block flange (4) for connecting the receiver tank is joined in a state where the buried portion (42) is buried in the header (1 1) of the heat exchanger body (10). Therefore, the installation space of the buried portion (42) can be omitted, and the size and size can be reduced.
- a flange-shaped partition (50) is integrally provided around the inlet of the inflow passage (4a) at the upper end face of the buried part (42), and the partition (50) is used to install one flange (11) inside the header (11). Is divided into a condensing section (1) and a subcooling section (2), so the partitioning member for separating the condensing section (1) and the supercooling section (2) is separately provided separately. Since there is no need to assemble, the number of parts can be reduced accordingly, and the assembling work can be performed easily, and the cost can be reduced.
- part (42) of the block flange (4) is embedded in one header (1 1), the receiver tank (4) joined to the block flange (4) is replaced with the header (1). 1) As close as possible, the entire heat exchanger can be made smaller.
- the inflow side of the inflow path (4a) in the block flange (4) is lowered, and the outflow side end of the inflow path (4a) is positioned lower than the inflow side end. Therefore, the installation position of the receiver tank (3) can be arranged entirely below, and accordingly, a receiver tank (3) having a long size can be used. Accordingly, a sufficiently large tank capacity of the receiver tank (3) can be ensured, a stable area in a supercooled state of the refrigerant is widened, and an excessive amount of the refrigerant and an insufficient amount of the refrigerant can be prevented. The refrigeration performance can be obtained, and the refrigeration performance can be improved. Furthermore, since a long tank can be used as the receiver tank (3), it is possible to use a tank with a small diameter while securing sufficient tank capacity. Can be planned.
- the descending flow path (40a) in the inflow path (4a) of the block flange (4) is inclined with respect to the axis of the header (11), and the descending flow path (40 Since the upper opening surface of a) is perpendicular to the axis of the header (11), the upper opening area of the downflow channel (40a) should be smaller than the area of the downflow channel (40a). It can be formed large. In this way, the opening area of the upper end of the descending flow path (40a) can be formed large, so that the refrigerant can be efficiently and smoothly introduced, the pressure loss can be reduced, and the refrigerant is supplied in a more stable state. And the refrigeration performance can be further improved.
- the opening area at the upper end of the downflow channel (40a) (condensing section outlet lb) is set to be as large as about 62 mm2.
- the entrance member is formed separately from the tank body.
- the present invention is not limited to this, and may be applied to a case where the entrance member is integrally formed with the tank body. it can.
- the number of passes of the heat exchanger body and the number of heat exchange tubes in each pass are not limited to those described above.
- the receiver tank (3) is assembled to the heat exchanger integrated with the supercooling section.
- the present invention is not limited to this. It may be assembled to a heat exchanger such as a condenser having no supercooling section.
- the desiccant layer (312) is provided at the upper end of the tank body (30).
- the present invention is not limited to this, and the desiccant layer (3 12) may be fixed to the middle or lower part of the tank body (30), and the desiccant layer may be arranged in the tank body in a loose state.
- the filter layer (335) it is not always necessary to use a nonwoven fabric, but other fiber complex, for example, a woven fabric or a knitted fabric, may be used. And the like consisting of a desiccant such as In short, any material that can provide resistance to the flow of the refrigerant may be used.
- the refrigeration cycle receiver unit, the heat exchanger with a receiver tank, and the refrigeration cycle condensing device according to the present invention can be suitably used for air conditioning systems for automobiles, homes, and businesses.
