[0030] With the popularity of vehicles, people have higher and higher requirements for the comfort of riding. At present, air conditioners are installed on general vehicles to adjust the temperature in the passenger compartment.

[0031] When the air conditioner is in refrigeration operation, the air in the cabin exchanges heat when flowing through the evaporator, and water vapor in the air condenses to form condensed water. Considering that the temperature of the condensed water is low, direct discharge will waste energy. At present, low-temperature condensed water is usually drained to the condenser to reduce the inlet air temperature of the condenser to improve the condensing effect.

[0032] However, at present, a pump needs to be arranged in the condensed water collecting mechanism, and the condensed water is transported to the condenser by the work of the pump, which increases the energy consumption of the air conditioner.

[0033] The utility model provides a kind of vehicle air conditioner.

[0034] Please refer to Figure 1 In an embodiment of the utility model, the vehicle air conditioner includes a compressor 110, a condenser 120, a throttle valve 130 and an evaporator 140. The compressor 110, the condenser 120, the throttle valve 130 and the evaporator 140 are connected in communication to form a refrigerant circuit 150. A condensed water recovery mechanism 200 is arranged between the evaporator 140 and the condenser 120. The condensed water recovery mechanism 200 is used to spray the condensed water generated by the evaporator 140 to the condenser 120. The height of the evaporator 140 is higher than that of the condensed water recovery mechanism 200.

[0035] Specifically, when the air conditioner is working, the compressor 110 works to compress the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. The low-temperature and medium-pressure liquid refrigerant is obtained by cooling through the condenser 120, and then the pressure is reduced through the expansion valve, and the low-temperature and low-pressure gaseous flow is returned to the compressor 110 through the evaporator 140.

[0036] When the air conditioner is in refrigeration, the high-temperature and high-humidity air becomes low-temperature air after passing through the evaporator 140, and the humidity is also reduced. The high-humidity molecules in the air are condensed into condensed water on the surface of the evaporator 140, and the temperature of the condensed water is low. At the same time, the high-temperature and high-pressure gaseous refrigerant at the outlet of the compressor 110 needs to be cooled through the condenser 120 to obtain liquid refrigerant. In summer, the temperature is high, and the air temperature at the inlet of the condenser 120 is also high. If the inlet air temperature can be reduced, a higher temperature difference can be obtained to improve the condensing efficiency and reduce the energy consumption.

[0037] The utility model discloses a condensate water recovery mechanism 200 is arranged between evaporator 140 and condenser 120, and the condensate water recovery mechanism 200 is used to deliver the low temperature condensate water of evaporator 140 to the import air before condenser 120, thereby reducing the air temperature at the import, and the high specific heat condensate water can take away higher heat, thereby greatly improving the condensing efficiency of condenser 120 and reducing energy consumption.

[0038] Meanwhile, in the utility model, evaporator 140 is arranged above condensate water recovery mechanism 200, so that the condensate water produced by evaporator 140 can directly flow into condensate water recovery mechanism 200 by gravity, thereby avoiding setting additional power parts, and thus being favorable to reducing the energy consumption of vehicle air conditioner.

[0039] The technical scheme of the utility model sets condensate water recovery mechanism 200 in vehicle air conditioner, sprays the condensate water produced by evaporator 140 on condenser 120, thereby reducing the air temperature at the import of condenser 120, improving the condensing efficiency of condenser 120 and reducing the energy consumption of vehicle air conditioner. Meanwhile, the height of evaporator 140 is higher than the height of condensate water recovery mechanism 200, so that the condensate water can directly drip into condensate water recovery mechanism 200 by gravity, thereby avoiding the use of additional power parts, and thus further reducing the energy consumption of vehicle air conditioner.

[0040] Please refer to Figures 1 to 3 In the embodiment of the utility model, condensate water recovery mechanism 200 includes drainage pipe 210 communicated with the water collecting disc under evaporator 140, flow collecting pipe 220 with one end communicated with drainage pipe 210 and the other end blocked, and shunt pipe 230 with one end communicated with flow collecting pipe 220 and the other end blocked, shunt pipe 230 extends along the up-down direction, and shunt pipe 230 is provided with multiple shunt holes 231 from top to bottom; condensate water flows into shunt pipe 230 through drainage pipe 210 and flow collecting pipe 220, and is sprayed to condenser 120 through shunt hole 231.

[0041] Specifically, in the scheme shown in the drawings of the present application, the condensed water recovery mechanism 200 includes a drainage pipe 210, a collecting pipe 220 and a distribution pipe 230. It can be understood that the evaporator 140 is provided with a water collecting tray (not shown) below, and the condensed water generated on the surface of the evaporator 140 flows downward under the action of gravity and drips into the water collecting tray. In an embodiment, a water inlet hole is provided on the water collecting tray, and one end of the drainage pipe 210 is connected with the water inlet hole to introduce the condensed water into the condensed water recovery mechanism 200. Along the length direction of the collecting pipe 220, one end of the collecting pipe 220 is connected with the drainage pipe 210, and the other end is blocked to avoid the condensed water flowing out. The collecting pipe 220 is also connected with the distribution pipe 230, and the distribution pipe 230 extends in the up-down direction. It is worth noting that the up-down direction here refers to the height direction of the vehicle. A plurality of distribution holes 231 are provided on the distribution pipe 230, and the condensed water is sprayed out of the distribution holes 231 to spray on the condenser 120. In an embodiment, the plurality of distribution holes 231 are uniformly and spaced arranged on the distribution pipe 230 to ensure that the amount of condensed water received by the condenser 120 in the up-down direction is basically consistent, thereby improving the uniformity and consistency of the condensing effect of the condenser 120.

[0042] Of course, in other embodiments, the condensed water recovery mechanism 200 can also include a recovery pipe and a spray head, one end of the recovery pipe is connected with the water collecting tray, and the other end is connected with the spray head. The condensed water flows from the water collecting tray into the recovery pipe and is sprayed onto the condenser 120 through the spray head, which can also reduce the inlet air temperature of the condenser 120 and absorb the heat on the surface of the condenser 120 through the evaporation of the condensed water, thereby improving the condensing efficiency and reducing the load of the system.

[0043] Please refer to Figures 1 to 3 In the embodiment of the present application, the vehicle air conditioner further includes a fan 160 arranged beside the condenser 120, the collecting pipe 220 and the distribution pipe 230 are located on the air inlet side of the condenser 120, the distribution holes 231 are arranged on the side wall of the distribution pipe 230 between the side wall facing the condenser 120 and the side wall facing the fan 160, and the fan 160 is used to spray the condensed water flowing out of the distribution pipe 230 onto the condenser 120.

[0044] Specifically, in the scheme shown in the drawings of the present application, the condenser 120 is also provided with a fan 160, and the air outlet of the fan 160 is aligned with the condenser 120, thereby improving the air flow speed at the condenser 120 and improving the heat exchange efficiency. The collecting pipe 220 and the distribution pipe 230 are arranged on the air inlet side of the condenser 120, and the opening direction of the distribution holes 231 on the distribution pipe 230 is intersected with the air outlet direction of the fan 160, so that the air outlet of the fan 160 can blow the condensed water flowing out of the distribution pipe 230 onto the condenser 120, without the need to set an additional power device.

[0045] In an embodiment, the opening direction of the shunt hole 231 on the shunt pipe 230 is perpendicular to the air outlet direction of the fan 160, so that all the condensed water can be sprayed on the condenser 120 as much as possible, the utilization rate of the condensed water is improved, and the condensing efficiency of the condenser 120 is improved, and the energy consumption of the vehicle air conditioner is reduced.

[0046] It can be understood that the vehicle air conditioner includes an indoor unit and an outdoor unit, wherein the indoor unit includes the evaporator 140, and in an embodiment, the evaporator 140 is installed in the passenger compartment of the vehicle, such as under the instrument panel, inside the center console, or the like. The outdoor unit includes the condenser 120, and in an embodiment, the condenser 120 is installed at the front end of the vehicle, such as behind the front bumper, in the engine compartment, or the like. When the vehicle air conditioner is used, the high-temperature and high-humidity ambient air passes through the evaporator 140 to generate low-temperature and low-humidity air into the passenger compartment of the vehicle, and the hot and humid air passing through the condenser 120 is discharged from the vehicle air conditioner to the outside environment. In this way, the use comfort of the vehicle air conditioner is ensured.

[0047] Please refer to Figure 2 In the embodiment of the utility model, the pipe diameter of the collecting pipe 220 gradually increases in the direction away from the drainage pipe 210.

[0048] Specifically, it can be understood that a plurality of shunt pipes 230 are arranged in the condensed water recovery mechanism 200, and the plurality of shunt pipes 230 are in communication with the collecting pipe 220, so that the spraying area of the condensed water sprayed on the condenser 120 is increased, and the condensing efficiency of the condenser 120 is improved. The plurality of shunt pipes 230 are arranged side by side along the extension direction of the collecting pipe 220. In order to ensure that the flow of condensed water flowing through each shunt pipe 230 is equal, the pipe diameter of the collecting pipe 220 gradually increases in the direction away from the drainage pipe 210, so that the amount of condensed water sprayed at different positions of the condenser 120 is basically consistent, thereby facilitating the consistency and uniformity of the condensing effect of the condenser 120.

[0049] In the embodiment of the utility model, the hole diameter of the plurality of shunt holes 231 gradually increases in the direction away from the collecting pipe 220.

[0050] Specifically, it can be understood that in the scheme of the utility model, the shunt pipe 230 extends in the up-down direction, and the condensed water can flow into the shunt pipe 230 from the collecting pipe 220 by gravity. In order to ensure that the amount of condensed water sprayed by the shunt hole 231 at the upper part of the shunt pipe 230 is basically consistent with the amount of condensed water sprayed by the shunt hole 231 at the lower part of the shunt pipe 230, the hole diameter of the plurality of shunt holes 231 gradually increases in the direction away from the collecting pipe 220. In this way, in the up-down direction, the condensed water is uniformly sprayed on the condenser 120, thereby facilitating the consistency and uniformity of the condensing effect of the condenser 120.

[0051] Referring to Figure 2 In the embodiment of the present application, the shunt pipes 230 are arranged side by side, and the multiple shunt pipes 230 are respectively connected to the collecting pipe 220, and the multiple shunt pipes 230 are respectively arranged in one-to-one correspondence with the multiple heat dissipation pipes 121 of the condenser 120.

[0052] Specifically, for the convenience of description, the condenser 120 is defined to have a certain height and length, wherein the height direction is the above-mentioned up-down direction, and the length direction is perpendicular to the height direction. The length direction of the collecting pipe 220 is consistent with the length direction of the condenser 120, and in an embodiment, the collecting pipe 220 is arranged corresponding to the upper end of the condenser 120. It can be understood that the condenser 120 includes multiple heat dissipation pipes 121 extending in the up-down direction, and the multiple shunt pipes 230 are respectively arranged in one-to-one correspondence with the multiple heat dissipation pipes 121. That is, in the direction from the fan 160 to the condenser 120, the projection of the shunt pipe 230 falls on the heat dissipation pipe 121. In this way, compared with the shunt pipe 230 being arranged staggered with the heat dissipation pipe 121, the corresponding arrangement of the shunt pipe 230 and the heat dissipation pipe 121 avoids increasing the wind resistance, thereby avoiding affecting the normal operation of the fan 160 and ensuring the condensing efficiency of the condenser 120.

[0053] In an embodiment, the pipe diameter of the shunt pipe 230 is equal to that of the heat dissipation pipe 121. In this way, compared with the scheme that the pipe diameter of the shunt pipe 230 is smaller than that of the heat dissipation pipe 121, the equal pipe diameter of the shunt pipe 230 and the heat dissipation pipe 121 is conducive to the spraying of the condensate water. Compared with the scheme that the pipe diameter of the shunt pipe 230 is larger than that of the heat dissipation pipe 121, the equal pipe diameter of the shunt pipe 230 and the heat dissipation pipe 121 avoids increasing the wind resistance and ensures the condensing efficiency of the condenser 120.

[0054] In an embodiment, between the two heat dissipation pipes 121 corresponding to the adjacent shunt pipes 230, there is at least one heat dissipation pipe 121.

[0055] Specifically, in the working process of the vehicle air conditioner, the generation of condensate water needs time, and the amount of condensate water is not large. In this way, an appropriate amount of shunt pipes 230 is arranged in the condensate water recovery mechanism 200 to spray the condensate water into the condenser 120. In an embodiment, between the two heat dissipation pipes 121 corresponding to the adjacent shunt pipes 230, there is at least one heat dissipation pipe 121. That is, the number of shunt pipes 230 is less than that of heat dissipation pipes 121. In this way, the reduction of the number of shunt pipes 230 is also conducive to reducing the wind resistance and ensuring the condensing efficiency of the condenser 120. In an embodiment, the shunt pipes 230 are uniformly spaced on the collecting pipe 220, and between the two heat dissipation pipes 121 corresponding to the adjacent shunt pipes 230, there can be one, two or three heat dissipation pipes 121, and the number of shunt pipes 230 is not limited herein.

[0056] Referring toFigure 2 and Figure 3 In the embodiment of the present application, the condensate water recovery mechanism 200 further comprises a bottom plate 240, and the ends of the plurality of shunt pipes 230 away from the collecting pipe 220 are installed on the bottom plate 240.

[0057] Specifically, the condensate water recovery mechanism 200 further comprises a bottom plate 240, so that the ends of the plurality of shunt pipes 230 away from the collecting pipe 220 can be connected together through the bottom plate 240, thereby facilitating to improve the structural strength of the condensate water recovery mechanism 200. In an embodiment, the length of the bottom plate 240 is consistent with the length of the collecting pipe 220.

[0058] In the embodiment of the present application, the condensate water recovery mechanism 200 is installed on the condenser 120 through the bottom plate 240. Thus, compared with installing the condensate water recovery mechanism 200 on the vehicle body, the present application installs the condensate water recovery mechanism 200 on the condenser 120, thereby avoiding the transmission of the vehicle body vibration to the condensate water recovery mechanism 200. In an embodiment, the bottom plate 240 is provided with a screw hole, and correspondingly, the shell of the condenser 120 is also provided with a screw hole, and a screw or a bolt passes through the two screw holes to install the condensate water recovery mechanism 200 on the condenser 120.

[0059] The present application also provides a vehicle, which comprises the vehicle air conditioner, and the specific structure of the vehicle air conditioner refers to the above-mentioned embodiments. Since the vehicle adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0060] The above-mentioned is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
