Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning equipment, specifically relating to automotive air conditioners. Background Technology

[0002] With the rise of RV tourism culture, RVs have become the preferred mode of transportation for more and more people. Of course, it's not just RVs; with the upgrading of related technologies and cost reductions in the automotive manufacturing industry, vehicles are being given more functions beyond just transportation, such as temporary duty stations, blood donation centers, and temporary aid stations, most of which are converted from existing vehicles. These vehicles, unlike cars for conventional purposes, require certain functions to be maintained properly after parking, such as air conditioning.

[0003] Automotive air conditioning typically consists of an indoor unit and an outdoor unit, with the indoor unit installed inside the vehicle cabin and the outdoor unit generally located on the roof. For example, existing technology discloses a split-type rooftop RV air conditioning system, including a rooftop indoor unit and an independent outdoor unit; the rooftop indoor unit includes a panel assembly and an evaporator assembly mounted on the roof; the independent outdoor unit includes a condenser assembly; the rooftop indoor unit is installed in a first position on the RV roof, and the independent outdoor unit is installed in a second position on the RV, the second position including other locations on the roof different from the first position, the RV body, or the RV floor.

[0004] As vehicles become increasingly versatile, especially motorhomes, travel to different regions may expose them to harsh climates such as strong winds, torrential rain, extreme heat, and frigid temperatures. Therefore, externally mounted air conditioning units have limitations in terms of safety and environmental tolerance. While air conditioners that integrate the evaporator and refrigeration systems into a single unit have emerged, their evaporator and refrigeration fans are limited to a single model, failing to meet the diverse climatic needs of different vehicles. Therefore, there is a need to design a new automotive air conditioner that can meet the diverse climatic requirements of different vehicles and improve the applicability of automotive air conditioning systems.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0053] The automobile air conditioner generally comprises an indoor unit and an outdoor unit, wherein the indoor unit is installed in the vehicle cabin and the outdoor unit is generally placed on the roof of the vehicle. As disclosed in the prior art, a split type roof-mounted motor home air conditioner system comprises a roof-mounted indoor unit and a separate outdoor unit. The roof-mounted indoor unit comprises a panel assembly and an evaporating assembly installed on the roof of the vehicle. The separate outdoor unit comprises a condensing assembly. The roof-mounted indoor unit is installed at a first position on the roof of the motor home, and the separate outdoor unit is installed at a second position on the motor home, which comprises other positions on the roof of the motor home, the body of the motor home or the bottom of the motor home, which are different from the first position.

[0054] With the increasing use of vehicles, especially motor homes, when traveling to different regions, strong winds, heavy rain, heat, cold and other weather conditions may be encountered. Therefore, the outdoor unit of the external type has limitations in safety and environmental tolerance. Although an air conditioner with an evaporating system and a refrigerating system integrated in one box has appeared, the evaporating fan and the refrigerating fan of the air conditioner are single in type and cannot meet the needs of different vehicles in different weather conditions. Therefore, it is necessary to design an automobile air conditioner to meet the needs of different vehicles in different weather conditions and improve the applicability of the automobile air conditioner.

[0055] It should be understood that the "evaporating system 2" and the "condensing system 3" in the present application are both internal components of the air conditioner. According to general naming habits, the part installed indoors or the part for temperature regulation and heat exchange in the room is called "evaporating system 2", and the part installed outdoors or the part for heat exchange with outdoor air is called "condensing system 3". When the air conditioner is working, in the refrigeration mode, the evaporator 21 of the evaporating system 2 absorbs indoor heat, and the condenser 31 of the condensing system 3 releases heat to the outdoor. In the heating mode, the air conditioner changes the flow direction of the refrigerant through the internal four-way reversing valve to exchange the functions of the evaporator 21 and the condenser 31, but the installation positions of the evaporator 21 and the condenser 31 cannot be exchanged. At this time, the evaporator 21 located in the room releases heat to the room, and the condenser 31 located outdoors absorbs outdoor heat.

[0056] It should be noted that the temperature regulating gas refers to the gas for temperature regulation in the environment to be regulated (refrigeration or heating area). The gas in the area to be regulated enters the first cavity 11 through the first air inlet 111 and exchanges heat in the first cavity 11, and the temperature of the gas increases or decreases, and then is blown out to the area to be regulated through the first air outlet 112 to heat or cool the area to be regulated.

[0057] In contrast, the so-called medium gas refers to the gas from an area outside the temperature-controlled environment (cooling or heating zone). After entering the second cavity 12, this gas exchanges heat with the condensing system 3. The condensing system 3 absorbs heat from these gases and then releases heat back into them. After exchanging heat with the condensing system 3, these gases are finally discharged from the second air outlet 122 to an area outside the temperature-controlled environment (cooling or heating zone). This gas does not enter the temperature-controlled environment and does not directly heat or cool the temperature-controlled environment. Therefore, these gases are referred to as medium gases.

[0058] In the attached diagram, the trajectories marked with "air intake" and "air exhaust" represent the movement of the temperature-regulating gas or medium gas within the vehicle's air conditioning unit.

[0059] Example 1:

[0060] like Figures 1-3 As shown, this automotive air conditioner includes a housing 1, an evaporation system 2, and a condensation system 3. The housing 1 contains a first cavity 11 and a second cavity 12 spaced apart. The evaporation system 2 is installed within the first cavity 11, which has a first air inlet 111 and a first air outlet 112. The evaporation system 2 includes an evaporator 21 and an evaporation fan 22. Temperature-regulating gas enters the first cavity 11 through the first air inlet 111, undergoes heat exchange through the evaporator 21, and is then blown out through the first air outlet 112 by the evaporation fan 22. The first air inlet 111 and the first air outlet... All 112 are oriented towards the area to be regulated; the evaporator fan 22 is a forward-curved double-sided centrifugal fan or a forward-curved single-sided centrifugal fan; the condensing system 3 is installed in the second cavity 12, the second cavity 12 is provided with a second air inlet 121 and a second air outlet 122, the condensing system 3 includes a condenser 31 and a condensing fan 32; the medium gas enters the second cavity 12 through the second air inlet 121, and after heat exchange through the condenser 31, the heat-exchanged medium gas is blown out from the second air outlet 122 by the condensing fan 32, the condensing fan 32 is a forward-curved double-sided centrifugal fan, a backward-curved centrifugal fan or an axial flow fan.

[0061] like Figure 1 and 2 As shown, in this embodiment, the evaporator fan 22 is a forward-curved double-sided centrifugal fan; the condenser fan 32 is a forward-curved double-sided centrifugal fan.

[0062] When the air conditioner of the vehicle is working, medium gas enters the second cavity 12 through the second air inlet 121 and passes through the condenser 31, and is finally blown out by the condensing fan 32 and discharged through the second air outlet 122; the condensing fan 32 works to suck in medium gas through the second air inlet 121, and after the medium gas enters the second cavity 12, it will contact the condenser 31, exchange heat with the condenser 31, and then be blown out through the air outlet of the condensing fan 32, and the medium gas blown out by the condensing fan 32 is directly discharged through the second air outlet 122 and into an area outside the temperature-adjusted environment (refrigeration or heating area). The temperature-adjusted gas enters the first cavity 11 through the first air inlet 111 and passes through the evaporator 21, and is finally blown out by the evaporating fan 22 and discharged through the first air outlet 112; the evaporating fan 22 works to suck in temperature-adjusted gas through the first air inlet 111, and after the temperature-adjusted gas enters the first cavity 11, it will contact the evaporator 21, exchange heat with the evaporator 21, and then be blown out through the air outlet of the evaporating fan 22, and the temperature-adjusted gas blown out by the evaporating fan 22 is directly discharged through the first air outlet 112 and into the temperature-adjusted environment, achieving temperature adjustment of the temperature-adjusted environment. Since the evaporating fan 22 can be a forward double-sided centrifugal fan or a forward single-sided centrifugal fan, and the condensing fan 32 can be a forward double-sided centrifugal fan or a backward centrifugal fan or an axial flow fan, different types of evaporating fans 22 and condensing fans 32 are selected according to different climate environments to meet the needs of different vehicles in different climate environments, greatly improving the applicability of the vehicle air conditioner.

[0063] As Figure 2 and 3As shown, in the embodiment, the box 1 is further provided with a flow equalizing cavity 13, the first cavity 11 is isolated from the flow equalizing cavity 13, the flow equalizing cavity 13 comprises a first end 131 and a second end 132, the first end 131 is close to the air outlet of the evaporative fan 22, and the second end 132 is provided with the first air outlet 112. Specifically, the central axes of the air outlet of the evaporative fan 22, the flow equalizing cavity 13 and the first air outlet 112 are located in the same horizontal plane. In this structure, since the central axes of the air outlet of the evaporative fan 22, the flow equalizing cavity 13 and the first air outlet are located in the same horizontal plane, that is, the temperature-adjusted gas blown out of the air outlet of the evaporative fan 22 is directly blown into the flow equalizing cavity 13 without flowing through other fluid channels, without changing the direction of the blown-out heat exchange gas, avoiding the loss of wind energy, ensuring a larger air volume, and the heat exchange gas moves in the flow equalizing cavity 13 from the first end 131 to the second end 132 and is blown out of the first air outlet, ensuring uniform blowing from the first air outlet, more uniform wind speed, and providing a more comfortable experience for the user. The function of the flow equalizing cavity 13 is to ensure that the temperature-adjusted gas is more concentrated and uniformly blown out of the first air outlet 112 by introducing the temperature-adjusted gas into a closed cavity, so that the temperature-adjusted gas has greater thrust when being sent out, thereby being able to cover a longer distance, and the temperature-adjusted gas does not collide with the inner wall of the flow equalizing cavity 13, reducing the noise of the heat exchange gas and ensuring the air conditioner to be quiet.

[0064] As shown in Figure 2 and 3 In the embodiment, the cross-sectional area of the first end 131 of the flow equalizing cavity 13 is greater than the cross-sectional area of the second end 132. In this structure, the cross-sectional area of the first end 131 of the flow equalizing cavity 13 is greater than the cross-sectional area of the second end 132, so that when the temperature-adjusted gas is blown into the flow equalizing cavity 13 through the air outlet of the evaporative fan 22, the temperature-adjusted gas is more concentrated in the flow equalizing cavity 13, and the wind speed is greater and more uniform when the temperature-adjusted gas is blown out of the first air outlet 112.

[0065] As shown in Figure 2 and 3 In the embodiment, the direction from the first end 131 to the second end 132 is the first direction, the direction of the heat exchange gas blown out by the evaporative fan 22 into the flow equalizing cavity 13 is the second direction, and the first direction is parallel to the second direction. In this structure, the first direction is parallel to the second direction, that is, the temperature-adjusted gas blown out of the air outlet of the evaporative fan 22 is directly blown into the flow equalizing cavity 13 without flowing through other fluid channels, without changing the direction of the blown-out temperature-adjusted gas, avoiding the loss of wind energy, and ensuring a larger air volume.

[0066] In some embodiments, the first direction and the second direction can also be non-parallel, and an included angle between the first direction and the second direction can be set to be less than 45 degrees, so as to leave a fault-tolerant space for the installation combination of the evaporative fan 22 and the flow uniformization cavity 13, that is, the air outlet of the evaporative fan 22 and the flow uniformization cavity 13 can not be on a straight line, and there can be a slight deviation, which on one hand facilitates the assembly of the evaporative fan 22 and the flow uniformization cavity 13 and improves the assembly efficiency, and on the other hand, the gas blown out of the air outlet of the evaporative fan 22 can also smoothly flow into the flow uniformization cavity 13.

[0067] Specifically, the evaporator 21 is arranged close to the first air inlet 111, the evaporative fan 22 is arranged on the side of the evaporator 21 away from the first air inlet 111, the temperature-adjusting gas enters the first cavity 11 through the first air inlet 111 and passes through the evaporator 21, and finally is blown out by the evaporative fan 22 and blown out by the first air outlet 112. The condenser 31 is arranged close to the second air inlet 121, the condensing fan 32 is arranged on the side of the condenser 31 away from the second air inlet 121, the medium gas enters the second cavity 12 through the second air inlet 121 and passes through the condenser 31, and finally is blown out by the condensing fan 32 and blown out by the second air outlet 122.

[0068] Specifically, the first air inlet 111 is arranged at the bottom, top or side of the cabinet 1, and the first air outlet 112 is arranged at the bottom, top or side of the cabinet 1. In this structure, the first air inlet 111 is arranged at the bottom, top or side of the cabinet 1, and the first air outlet 112 is arranged at the bottom, top or side of the cabinet 1, that is, the positions of the first air inlet 111 and the first air outlet 112 can be determined according to the installation position inside the automobile, for example, if the automobile air conditioner is installed on the ceiling of the vehicle, the first air inlet 111 and the first air outlet 112 can be arranged on the side or bottom of the shell, so as to ensure that the front of the first air inlet 111 and the first air outlet 112 is not blocked after installation.

[0069] Specifically, the second air inlet 121 is arranged at the bottom, top or side of the cabinet 1, and the second air outlet 122 is arranged at the bottom, top or side of the cabinet 1, and the second air outlet 122 and the second air inlet 121 are arranged with a height difference in the height direction of the cabinet 1. In this structure, the second air inlet and the second air outlet are arranged with a height difference in the height direction of the cabinet 1, so as to avoid interference between the condensing system 3 and the air inlet and air outlet, to avoid the second air inlet from inhaling a large amount of air discharged by the second air outlet as much as possible, and to ensure the heat exchange efficiency of the condenser 31.

[0070] In some embodiments, the direction of the second air outlet can be at an angle of 0 to 45 degrees to the direction of the second air inlet, so that the second air inlet and the second air outlet face different directions, further avoiding interference between the air intake and exhaust of the condensing system 3, that is, avoiding the second air inlet from drawing in a large amount of gas discharged from the second air outlet, and ensuring the heat exchange efficiency of the condenser 31.

[0071] Preferably, the first air outlet 112 includes several independent small air outlets, each of which is located on the same or different surfaces of the housing 1. In this structure, if each small air outlet is located on two or more different surfaces, air can be delivered to different directions of the area to be regulated, enabling rapid temperature regulation of the area and ensuring uniform temperature at various locations within the regulated area.

[0072] Example 2:

[0073] like Figure 4 and 5 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 1, except that:

[0074] The evaporator fan 22 is a forward-curved single-sided centrifugal fan.

[0075] In this embodiment, the condenser fan 32 is also a forward-facing double-sided centrifugal fan. Since the central axes of the airflow outlet, the flow equalization chamber 13, and the first air outlet of the evaporator fan 22 are located on the same horizontal plane, the temperature-regulating gas blown out of the airflow outlet of the evaporator fan 22 is directly blown into the flow equalization chamber 13 without having to flow through other fluid channels or change the direction of the blown heat exchange airflow. This avoids energy loss and ensures a larger air volume. Furthermore, the heat exchange airflow moves from the first end 131 to the second end 132 within the flow equalization chamber 13 and is blown out from the first air outlet, ensuring that the airflow is evenly blown out from the first air outlet, resulting in a more uniform airflow speed and a more comfortable user experience. The function of the flow equalization cavity 13 is to ensure that the temperature-regulating gas is more concentrated and blown out evenly from the first air outlet 112 by introducing the temperature-regulating gas into a sealed cavity. This gives the temperature-regulating gas a greater thrust when it is delivered, thus covering a longer distance. In addition, the temperature-regulating gas does not collide with the inner wall of the flow equalization cavity 13, reducing the noise of the heat exchange airflow and ensuring that the air outlet of the air conditioner is quiet.

[0076] Example 3:

[0077] like Figures 6-8 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 1, except that:

[0078] The condenser fan 32 is a backward centrifugal fan.

[0079] In this embodiment, the evaporator fan 22 is also a forward-facing double-sided centrifugal fan. Since the central axes of the airflow outlet, the flow equalization chamber 13, and the first air outlet of the evaporator fan 22 are located on the same horizontal plane, the temperature-regulating gas blown out of the airflow outlet of the evaporator fan 22 is directly blown into the flow equalization chamber 13 without having to flow through other fluid channels or change the direction of the blown heat exchange airflow, thus avoiding energy loss and ensuring a larger air volume. Furthermore, the heat exchange airflow moves from the first end 131 to the second end 132 within the flow equalization chamber 13 and is blown out from the first air outlet, ensuring that the airflow is evenly blown out from the first air outlet, resulting in a more uniform airflow speed and a more comfortable user experience. The function of the flow equalization cavity 13 is to ensure that the temperature-regulating gas is more concentrated and blown out evenly from the first air outlet 112 by introducing the temperature-regulating gas into a sealed cavity. This gives the temperature-regulating gas a greater thrust when it is delivered, thus covering a longer distance. In addition, the temperature-regulating gas does not collide with the inner wall of the flow equalization cavity 13, reducing the noise of the heat exchange airflow and ensuring that the air outlet of the air conditioner is quiet.

[0080] Example 4:

[0081] like Figures 9-11 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 3, except that:

[0082] The evaporator fan 22 is a forward-curved single-sided centrifugal fan.

[0083] In this embodiment, the condenser fan 32 is also a backward centrifugal fan. Since the central axes of the airflow outlet, the flow equalization chamber 13, and the first air outlet of the evaporator fan 22 are located on the same horizontal plane, the temperature-regulating gas blown out of the airflow outlet of the evaporator fan 22 is directly blown into the flow equalization chamber 13 without having to flow through other fluid channels or change the direction of the blown heat exchange airflow. This avoids energy loss and ensures a larger air volume. Furthermore, the heat exchange airflow moves from the first end 131 to the second end 132 within the flow equalization chamber 13 and is blown out from the first air outlet, ensuring that the airflow is evenly blown out from the first air outlet, resulting in a more uniform airflow speed and a more comfortable user experience. The function of the flow equalization cavity 13 is to ensure that the temperature-regulating gas is more concentrated and blown out evenly from the first air outlet 112 by introducing the temperature-regulating gas into a sealed cavity. This gives the temperature-regulating gas a greater thrust when it is delivered, thus covering a longer distance. In addition, the temperature-regulating gas does not collide with the inner wall of the flow equalization cavity 13, reducing the noise of the heat exchange airflow and ensuring that the air outlet of the air conditioner is quiet.

[0084] Example 5:

[0085] like Figures 12-14 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 1, except that:

[0086] The condenser fan 32 is a backward axial flow fan.

[0087] In this embodiment, the evaporator fan 22 is also a forward-facing double-sided centrifugal fan. Since the central axes of the airflow outlet, the flow equalization chamber 13, and the first air outlet of the evaporator fan 22 are located on the same horizontal plane, the temperature-regulating gas blown out of the airflow outlet of the evaporator fan 22 is directly blown into the flow equalization chamber 13 without having to flow through other fluid channels or change the direction of the blown heat exchange airflow, thus avoiding energy loss and ensuring a larger air volume. Furthermore, the heat exchange airflow moves from the first end 131 to the second end 132 within the flow equalization chamber 13 and is blown out from the first air outlet, ensuring that the airflow is evenly blown out from the first air outlet, resulting in a more uniform airflow speed and a more comfortable user experience. The function of the flow equalization cavity 13 is to ensure that the temperature-regulating gas is more concentrated and blown out evenly from the first air outlet 112 by introducing the temperature-regulating gas into a sealed cavity. This gives the temperature-regulating gas a greater thrust when it is delivered, thus covering a longer distance. In addition, the temperature-regulating gas does not collide with the inner wall of the flow equalization cavity 13, reducing the noise of the heat exchange airflow and ensuring that the air outlet of the air conditioner is quiet.

[0088] Example 6:

[0089] like Figures 15-17 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 5, except that:

[0090] The evaporator fan 22 is a forward-curved single-sided centrifugal fan.

[0091] In this embodiment, the condenser fan 32 is a backward axial flow fan. Since the central axes of the airflow outlet, the flow equalization chamber 13, and the first air outlet of the evaporator fan 22 are located on the same horizontal plane, the temperature-regulating gas blown out of the airflow outlet of the evaporator fan 22 is directly blown into the flow equalization chamber 13 without having to flow through other fluid channels or change the direction of the blown heat exchange airflow. This avoids energy loss and ensures a larger air volume. Furthermore, the heat exchange airflow moves from the first end 131 to the second end 132 within the flow equalization chamber 13 and is blown out from the first air outlet, ensuring that the airflow is evenly blown out from the first air outlet, resulting in a more uniform airflow speed and a more comfortable user experience.

In addition, the temperature-regulating gas does not collide with the inner wall of the flow equalization cavity 13, reducing the noise of the heat exchange airflow and ensuring that the air outlet of the air conditioner is quiet.

[0092] Example 7:

[0093] like Figures 18-20 As shown, the air conditioner in this embodiment has a basically the same structure as that in Embodiment 1, except that:

[0094] The condenser fan 32 is an axial flow fan.

[0095] In the embodiment, the evaporative fan 22 is also a forward type double-side centrifugal fan. Since the airflow blowing outlet of the evaporative fan 22, the flow uniforming cavity 13 and the central axis of the first air outlet are located in the same horizontal plane, i.e. the temperature-adjusted gas blown out by the airflow blowing outlet of the evaporative fan 22 is directly blown into the flow uniforming cavity 13 without flowing through other fluid channels, without changing the air direction of the blown heat exchange gas flow, avoiding the loss of wind energy, ensuring a larger air volume, and the heat exchange gas flow moves in the flow uniforming cavity 13 from the first end 131 to the second end 132 and is blown out by the first air outlet, ensuring uniform blowing out from the first air outlet, more uniform air speed, and providing a more comfortable experience for the user. The flow uniforming cavity 13 functions to ensure that the temperature-adjusted gas is more concentrated and uniformly blown out from the first air outlet 112 by introducing the temperature-adjusted gas into a closed cavity, so that the temperature-adjusted gas has greater thrust when being sent out, thereby being able to cover a longer distance, and the temperature-adjusted gas does not substantially collide with the inner wall of the flow uniforming cavity 13, reducing the noise of the heat exchange gas flow and ensuring the air outlet silence of the air conditioner.

[0096] Embodiment Eight

[0097] As shown in the drawings, the air conditioner of the embodiment is basically the same as that of Embodiment Seven, and the difference lies in that: Figures 21-23

[0098] The evaporative fan 22 is a forward type single-side centrifugal fan.

[0099] In the embodiment, the condensing fan 32 is an axial fan. Since the airflow blowing outlet of the evaporative fan 22, the flow uniforming cavity 13 and the central axis of the first air outlet are located in the same horizontal plane, i.e. the temperature-adjusted gas blown out by the airflow blowing outlet of the evaporative fan 22 is directly blown into the flow uniforming cavity 13 without flowing through other fluid channels, without changing the air direction of the blown heat exchange gas flow, avoiding the loss of wind energy, ensuring a larger air volume, and the heat exchange gas flow moves in the flow uniforming cavity 13 from the first end 131 to the second end 132 and is blown out by the first air outlet, ensuring uniform blowing out from the first air outlet, more uniform air speed, and providing a more comfortable experience for the user.
