Description

Technical Field

[0001] The utility model belongs to the technical field related to vehicle air conditioners, and in particular relates to a vehicle-mounted condenser, a vehicle-mounted air conditioner and a vehicle. Background Art

[0002] The vehicle-mounted condenser is used to cool the high-temperature and high-pressure refrigerant vapor discharged from the compressor and condense it into liquid high-pressure refrigerant. According to the flow direction of the inlet and outlet, the condenser is divided into a downstream condenser and a countercurrent condenser. According to the number of processes, there are usually one-process, two-process, three-process and four-process condensers.

[0003] The drying cylinder is an important component of the condenser. The arrangement position of the drying cylinder on the condenser will directly affect the assembly space required for the overall assembly of the condenser. Among them, the inlet position of the drying cylinder in the co-current condenser is usually arranged below the condenser. The liquid refrigerant will flow into the cylinder of the drying cylinder preferentially due to the influence of gravity, so that the refrigerant quickly enters the last section of the co-current condenser, which will affect the heat exchange efficiency of the co-current condenser during operation; the inlet position of the drying cylinder in the countercurrent condenser is arranged above the co-current condenser. The refrigerant usually enters the cylinder of the drying cylinder in a mist state. The mist refrigerant will occupy a large volume of the initial liquid level in the cylinder before entering the last section of the process. This will cause the last section of the countercurrent condenser to fail to achieve the set liquefaction effect, thereby making the heat exchange capacity of the countercurrent condenser unable to be fully utilized.

[0018] The present application also seeks protection for a vehicle-mounted air conditioner, comprising the vehicle-mounted condenser described above.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] like Figure 1 , Figure 2As shown, a vehicle-mounted condenser 100 provided in an embodiment of the present application includes a condenser body 10 and a drying cylinder 20, the condenser body 10 has at least three refrigerant flows 11, at least two of the at least three refrigerant flows 11 are connected in a downstream manner, and at least two of the at least three refrigerant flows 11 are connected in a countercurrent manner; wherein, the condenser body 10 is divided into a first part 101 and a second part 102 in a vertical direction, the first part 101 is arranged below the second part 102, and is used to accommodate a refrigerant flow 11 located at the bottom position on the condenser body 10; the drying cylinder 20 is arranged in the area where the second part 102 is located and is connected to the two refrigerant flows 11 respectively. That is to say, the vehicle-mounted condenser 100 of the present application arranges the drying cylinder 20 in the middle and upper position of the condenser body 10, and the vehicle-mounted condenser 100 realizes the flow of the refrigerant in the refrigerant flow 11 on the condenser body 10 in a combination of downstream and countercurrent when working. In this process, the efficient heat dissipation of the refrigerant in downstream can be fully utilized. Here, the vehicle-mounted condenser 100 is specifically assembled in the car using the first part 101. It should be noted that the specific structure of the condenser body 10 and the drying cylinder 20 and the working principle of how the refrigerant performs heat exchange when flowing in the refrigerant flow 11 on the condenser body 10 and the drying cylinder 20 can all adopt the conventional method of the existing condenser, which will not be elaborated here.

[0030] It can be understood that arranging the drying cylinder 20 in the area where the second part 102 is located can reduce the space required for assembling the vehicle-mounted condenser 100 in the car, so that the vehicle-mounted condenser 100 can be assembled and used in a small space of the car; at the same time, a combination of downstream and countercurrent flow is adopted to realize the flow of the refrigerant in the refrigerant flow path 11 on the condenser body 10, which can ensure that the refrigerant discharged through the condenser body 10 is in liquid state. In this way, the heat exchange efficiency of the vehicle-mounted condenser 100 during operation can be ensured, so that the heat exchange capacity of the vehicle-mounted condenser 100 can be fully utilized.

[0031] like Figure 1 , Figure 2 As shown, the drying cylinder 20 has a refrigerant outlet 21, and the refrigerant outlet 21 is connected to a refrigerant flow path 11 located at the top position of the condenser body 10. In other words, when the vehicle-mounted condenser 100 is working, the refrigerant is discharged using the refrigerant flow path 11 located at the top position of the condenser body 10, that is, the vehicle-mounted condenser 100 uses the refrigerant flow path 11 at the top layer to discharge liquid refrigerant. Of course, in other embodiments, the refrigerant outlet 21 of the drying cylinder 20 can also be connected to other refrigerant flows 11 in the area where the second part 102 of the vehicle-mounted condenser 100 is located, and discharged.

[0032] like Figure 1 , Figure 2As shown, the condenser body 10 has an inlet 12, and the volume of the refrigerant flow path 11 on the condenser body 10 connected to the inlet 12 is greater than the volume of other refrigerant flow paths 11 on the condenser body 10. This allows the vehicle-mounted condenser 100 to fully utilize the high heat exchange efficiency when the refrigerant is just introduced, which can further improve the heat exchange efficiency of the vehicle-mounted condenser 100 when it is working. Here, the vehicle-mounted condenser 100 can control the volume of the refrigerant flow path 11 by controlling the height occupied by the refrigerant flow path 11 on the condenser body 10.

[0033] like Figure 1 As shown, the number of refrigerant flow paths 11 on the condenser body 10 is configured as four, and in the vertical direction of the condenser body 10, the four refrigerant flow paths 11 are sequentially set from bottom to top as the first flow path 111, the third flow path 113, the second flow path 112 and the fourth flow path 114. In other words, the vehicle-mounted condenser 100 is configured as a four-flow condenser.

[0034] like Figure 1 As shown, along the flow direction of the refrigerant, the first flow 111, the second flow 112, the third flow 113, the drying cylinder 20 and the fourth flow 114 are connected in sequence. That is to say, when the vehicle-mounted condenser 100 is working, the external gaseous refrigerant can flow in through the first flow 111, first flow to the second flow 112 in a countercurrent manner, then flow to the third flow 113 in a downstream manner, and then flow into the fourth flow 114 in a countercurrent manner through the drying cylinder 20, and finally the liquid refrigerant is discharged from the fourth flow 114.

[0035] like Figure 1 As shown, the vehicle-mounted condenser 100 also includes a first connecting pipe 30, which is connected and communicated with the condenser body 10, and the first process 111 can be communicated with the third process 113 through the first connecting pipe 30; that is, the refrigerant in the first process 111 can flow to the third process 113 in a countercurrent manner through the first connecting pipe 30.

[0036] like Figure 2 As shown, the number of refrigerant flow paths 11 on the condenser body 10 is configured as four, and in the vertical direction of the condenser body 10, the four refrigerant flow paths 11 are sequentially set from bottom to top as the third flow path 113, the second flow path 112, the first flow path 111 and the fourth flow path 114. In other words, the vehicle-mounted condenser 100 is also configured as a four-flow condenser.

[0037] like Figure 2As shown, along the flow direction of the refrigerant, the first flow 111, the second flow 112, the third flow 113, the drying cylinder 20 and the fourth flow 114 are connected in sequence. That is to say, when the vehicle-mounted condenser 100 is working, the external gaseous refrigerant can flow in through the first flow 111, first pass through the second flow 112 and the third flow 113 in a downstream manner, and then flow into the fourth flow 114 in a countercurrent manner through the drying cylinder 20, and finally the liquid refrigerant is discharged from the fourth flow 114.

[0038] like Figure 2 As shown, the vehicle-mounted condenser 100 also includes a second connecting pipe 40, which is connected and communicated with the condenser body 10, and the third process 113 can be communicated with the fourth process 114 through the second connecting pipe 40; that is, the refrigerant in the third process 113 can flow to the fourth process 114 in a countercurrent manner through the second connecting pipe 40.

[0039] It should be noted that the number of refrigerant flows 11 on the condenser body 10 in the vehicle-mounted condenser 100 of the present application is not limited to the four shown above. For those skilled in the art, the number of refrigerant flows 11 on the condenser body 10 can be set to three, five, or even more, and the co-current and countercurrent arrangement of the refrigerant flows 11 on the condenser body 10 can be specifically set according to the requirements of use, which will not be elaborated here.

[0040] The present application also provides a vehicle-mounted air conditioner, comprising the vehicle-mounted condenser 100 described above.

[0041] In addition, the present application also provides a car, comprising the above-mentioned vehicle air conditioner.

[0042] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present invention.
