The two-loop supercooling concurrent-flow condenser comprises a plurality of condensing tubes arranged in parallel and two collecting pipes arranged at two ends of the condensing tubes and vertically communicated with the condensing tubes, wherein each collecting pipe is internally provided with a plurality of clapboards causing the condensing tubes and the collecting pipes to form a plurality of flow dividing circuits; refrigerant is input through a refrigerant inlet arranged at the middle section of one collecting pipe and is output through a refrigerant outlet which is also arranged on the collecting pipe where the refrigerant inlet is arranged; and a stored liquid dryer is communicated with another collecting pipe through a connector. The two-loop supercooling concurrent-flow condenser is internally provided with a high-temperature area of the refrigerant corresponding to the largest flow area of a blower and has strong heat exchange capacity, compact structure and small volume.
Description
Technical field
The utility model relates to a kind of condenser of used for automobile air conditioning, particularly relates to a kind of parallel flow condenser of used for automobile air conditioning.
Background technology
At present, the parallel flow condenser of general used for automobile air conditioning is to constitute by some flat tubes that are arranged in parallel with perpendicular to their end and the header that communicates with it, is provided with in the header to make cold-producing medium form the dividing plate that turns back and flow out.The condenser cooling is to force to blow away by the air on its surface to take away heat by blower fan, thereby realizes heat exchange, and blower fan is installed normally at the condenser medium position.The flow process of existing automobile air conditioner parallel flow condenser internal refrigeration storage agent is the unidirectional flow direction of turning back, on one side after cold-producing medium flows into from condenser, via the blower fan cooling that is installed in the condenser middle part, flow out from the condenser another side.Because the place that refrigerant temperature is the highest flows into condenser one side of condenser at cold-producing medium, the medium position of the condenser that the big zone of condenser air flow then is mounted at blower fan, therefore make that zone and condenser surface Temperature Distribution that the condenser air flow is big are not corresponding, cause the condenser heat exchange efficiency lower.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the new structure condenser of a kind of double loop Overcold is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of double loop Overcold parallel flow condenser, be used for air conditioning for automobiles, comprise some condenser pipes that are arranged in parallel and be arranged at those condenser pipe two ends and perpendicular two headers that communicate, be provided with some dividing plates in each header, those dividing plates form a plurality of shunting circuits with described condenser pipe and header, this cold-producing medium is by being arranged at the wherein refrigerant inlet input in a header stage casing, and by refrigerant outlet output, this refrigerant outlet also is arranged on the described header with refrigerant inlet.
Described double loop Overcold parallel flow condenser also comprises the drier receiver that is connected with another header, this drier receiver communicates with described another header by connector, and described connector comprises that the cold-producing medium on the condenser pipe that is arranged at outside described a plurality of loop crosses head piece.
The advantage of the utility model parallel flow condenser is:
When double loop provided by the utility model Overcold parallel flow condenser was used for air conditioning for automobiles, the flow district correspondence of the high-temperature region of condenser internal refrigeration storage agent and blower fan maximum had improved the heat-exchange capacity of condenser.The agent of condenser internal refrigeration storage is flowed back to condenser more earlier through the super-dry liquid reservoir, through twice cooling, has guaranteed that cold-producing medium has enough degree of supercoolings.Drier receiver integrates by the header of connector and condenser, makes the air conditioner structure compactness, and the air-conditioning volume reduces.
Description of drawings
Accompanying drawing 1 is the structural representation of existing a kind of parallel flow condenser;
Accompanying drawing 2 is structural representations of a kind of double loop of the utility model Overcold parallel flow condenser.
The specific embodiment
Elaborate below in conjunction with the advantage of accompanying drawing a kind of double loop of the utility model Overcold parallel flow condenser, and provide a kind of specific embodiment of the present utility model, to need in order narrating clearly, to select to have the Overcold parallel flow condenser of limited dividing plate herein as example.
See also Fig. 1, a kind of parallel flow condenser of the prior art, comprise condenser pipe 11, first header 12, with second header 13, be provided with first dividing plate 123 and second partition 124 in first header 12, be provided with the 3rd dividing plate 133 in second header 13, cold-producing medium enters condenser from the refrigerant inlet 101 on first header, by first dividing plate 123, second partition 124, and the qualification of the 3rd dividing plate 133 and in condenser, form flow circuits, the flow direction of this flow circuits and and then flows out condensers by refrigerant outlet 102 shown in arrow among the figure.The flow direction of this existing automobile air conditioner parallel flow condenser internal refrigeration storage agent is the unidirectional flow direction of turning back.
See also Fig. 2, according to a kind of double loop of the present utility model Overcold parallel flow condenser, comprise condenser pipe 21, first header 22 and second header 23, be provided with first dividing plate 223, second partition 224 and the 3rd dividing plate 225 in the cavity of first header 22, first header 22 between described first dividing plate 223 and the second partition 224 is provided with refrigerant inlet 201, and described the 3rd dividing plate 225 annexes are provided with refrigerant outlet 202.Be provided with the 4th dividing plate 233, the 5th dividing plate 234 and the 6th dividing plate 235 in the cavity of described second header 23.
Please continue to consult Fig. 2, a kind of double loop of the utility model Overcold parallel flow condenser also comprises the drier receiver 24 with the 23 adjacent settings of described second header, this drier receiver 24 is connected with second header 23 by connector 25, this connector 25 comprises first connector 251 that is provided with near the 4th dividing plate 233, and is arranged at second connector 252 between described the 5th dividing plate 234 and described the 6th dividing plate 235.Being provided with the 3rd connector 253, the three connectors 253 near described the 6th dividing plate is used for the cold cold-producing medium of mistake is flowed into condenser from drier receiver 23.
During work, cold-producing medium enters condenser by refrigerant inlet 201, realize the two-phase shunting by the 4th dividing plate 233 and the 5th dividing plate 234, it flows to referring to the arrow points shown in Fig. 2, and and then turn back to second header 23 by first dividing plate 223 in first header 22 and second partition 224, enter drier receiver 24 by first connector 252 and second connector 252.Cold-producing medium by the defeated condenser that is back to of the 3rd connector 253 quilts, and then can export 202 outflow condensers by refrigerator after drier receiver 24 dry coolings.
