[0066] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0067] On the one hand, combined with Figures 1 to 5 As shown, this embodiment provides a HVAC system, which includes: an air inlet housing module 1 , a volute module 2 and a distributor module 3 .

[0068] The air inlet shell module 1 includes a shell air inlet 101 and a shell air outlet 102, the volute module 2 includes a volute air inlet 201 and a volute air outlet 202, and the distributor module 3 includes a distributor air inlet 301 and a distributor air outlet 302; the air inlet shell module 1 and the distributor module 3 are respectively connected to the volute module 2, and the shell air outlet 102 is connected to the volute air inlet 201, and the volute air outlet 202 is connected to the distributor air inlet 301.

[0069] The HVAC system also includes at least one of an adapter duct member 4 and a transition duct member 5; the adapter duct member 4 is connected to the air inlet shell module 1 and communicates with the shell air inlet 101; the transition duct member 5 is connected to the distributor module 3 and communicates with the distributor air outlet 302.

[0070] The HVAC system of this embodiment includes an air inlet housing module 1, a volute module 2 and a distributor module 3. The air inlet housing module 1 can introduce external or internal air into the vehicle, the volute module 2 can provide circulation power for the air, and the distributor module 3 can cool or heat the air to provide air conditioning functions such as cold air and warm air for the interior of the vehicle.

[0071] In order to adapt to the scene requirements of different vehicle models, an adapter air duct component 4 can be connected to the air inlet shell module 1, and the adapter air duct component 4 is connected to the shell air inlet 101 to adjust the position and / or direction of the shell air inlet 101. A transition air duct component 5 can also be connected to the distributor module 3, and the transition air duct component 5 is connected to the distributor air outlet 302 to adjust the position and / or direction of the distributor air outlet 302, so that the HVAC system can adapt to a variety of different vehicle models with height differences, size differences, etc., to achieve multi-model and multi-platform commonality of the HVAC system, and reduce the development cycle and development cost of the HVAC system.

[0072] When the HVAC system of this embodiment is working, air enters the air inlet shell module 1 from the shell air inlet 101, and then enters the volute module 2 through the shell air outlet 102 and the volute air inlet 201. After being driven by the volute module 2, the air enters the distributor module 3 through the volute air outlet 202 and the distributor air inlet 301. The distributor module 3 can perform cold or hot treatment on the air, or not. Then the air is blown out from the distributor air outlet 302 and enters the vehicle to achieve air conditioning in the vehicle.

[0073] In some possible implementations, the HVAC system includes an air inlet housing module 1, a volute module 2 and a distributor module 3, as well as an adapter air duct component 4, which is connected to the air inlet housing module 1 and communicates with the housing air inlet 101 for adjusting the position and / or direction of the housing air inlet 101.

[0074] Exemplarily, the HVAC system of this embodiment can be applied to sedans and SUVs. Since the opening of the front fender 6 of a sedan is lower, while the opening of the front fender 6 of an SUV is higher, the shell air inlet 101 can be consistent with the opening height of one of the front fenders 6, and the height of the shell air inlet 101 can be adjusted by using the adapter air duct member 4, so that the HVAC system can be adapted to the two types of vehicles respectively.

[0075] In some possible implementations, the HVAC system includes an air inlet housing module 1, a volute module 2, a distributor module 3, and a transition duct member 5, which is connected to the distributor module 3 and communicates with the distributor air outlet 302 for adjusting the position and / or direction of the distributor air outlet 302.

[0076] Exemplarily, after the adapter air duct member 4 is connected to the distributor air outlet 302 , the height of the distributor air outlet 302 increases to dock with the instrument panel 7 of a greater height.

[0077] Exemplarily, the HVAC system of this embodiment can be applied to sedans and SUVs. Since the dashboard 7 of a sedan is shorter and that of an SUV is taller, the air outlet of the distributor can be aligned with the height of one of the dashboards 7 , and the height of the distributor air outlet 302 can be adjusted by using the transition duct member 5 , so that the HVAC system can be adapted to the two types of vehicles respectively.

[0078] In some possible implementations, the HVAC system includes an air inlet housing module 1, a volute module 2 and a distributor module 3, as well as an adapter air duct component 4 and a transition air duct component 5. The adapter air duct component 4 is connected to the air inlet housing module 1 and communicates with the housing air inlet 101, and is used to adjust the position and / or direction of the housing air inlet 101. The transition air duct component 5 is connected to the distributor module 3 and communicates with the distributor air outlet 302, and is used to adjust the position and / or direction of the distributor air outlet 302.

[0079] In some possible implementations, reference Figure 5 and Figure 6 As shown, the transition duct member 5 is detachably connected to the distributor module 3. Exemplarily, a third buckle structure 51 is provided on the transition duct member 5, and a fourth buckle structure 35 is provided on the distributor module 3. The third buckle structure 51 and the fourth buckle structure 35 are buckled and connected, so that the transition duct member 5 and the distributor module 3 are detachably connected together.

[0080] In some other possible implementations, refer to Figure 8 and Fig. 9 As shown, the adapter air duct member 4 and the air inlet housing module 1 are detachably connected. Exemplarily, a second buckle structure 41 is provided on the adapter air duct member 4, and a first buckle structure 14 is provided on the air inlet housing module 1. The first buckle structure 14 and the second buckle structure 41 are buckled and connected, so that the adapter air duct member 4 and the air inlet housing module 1 are detachably connected together.

[0081] Combination Figure 3 and Figure 4 As shown, in some embodiments, the volute module 2 includes a fan assembly 21 and a volute body 22; the fan assembly 21 and the volute body 22 are connected in the left-right direction, the volute air inlet 201 is located on the top surface of the fan assembly 21, and the volute air outlet 202 is located on the rear side of the volute body 22; the air inlet housing module 1 is located above the fan assembly 21, and the distributor module 3 is located on the rear side of the volute body 22.

[0082] Through the above arrangement, the volute module 2 can utilize the fan assembly 21 to drive the air flow, and the volute body 22 provides a flow path for the air, so that the air can flow to the distributor module 3 according to the target trajectory.

[0083] In this embodiment, the air inlet housing module 1 is arranged above the fan assembly 21, and the distributor module 3 is arranged on the rear side of the volute body 22, so that the HVAC system has a better integration effect and can reduce the volume occupied by the HVAC system. If it is necessary to explain, the directions such as the rear side and the rear side in this embodiment refer to the HVAC system installed behind the vehicle, with the front and rear directions of the vehicle as the reference system.

[0084] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the fan assembly 21 includes a centrifugal fan 211 , the axis of the centrifugal fan 211 is arranged in a vertical direction, and the volute air inlet 201 and the shell air outlet 102 are respectively located on the axis of the centrifugal fan 211 .

[0085] In this embodiment, the fan assembly 21 uses the internal centrifugal fan 211 to provide flow power for the air. The axis of the centrifugal fan 211 is arranged in the vertical direction, which can make the centrifugal fan 211 have better rotation stability during rotation, which is conducive to reducing the noise level of the HVAC system. The volute air inlet 201 and the shell air outlet 102 just correspond to the air inlet direction of the centrifugal fan 211, and the kinetic energy loss of the centrifugal fan 211 is smaller, which is conducive to improving the air volume and other air supply effects of the volute module 2.

[0086] Combination Figure 1 As shown, in some embodiments, the axis of the centrifugal fan 211 is located in a vertical section passing through the center point of the housing air inlet 101. Through the above arrangement, the axis of the centrifugal fan 211 is coplanar with the center point of the housing air inlet 101 in the front-to-back direction, the center line of the air inlet housing module 1 tends to be coplanar with the axis of the centrifugal fan 211, and when the air inlet housing module 1 is arranged on the fan assembly 21, the fan assembly 21 can provide good bottom support for the air inlet housing, and the air inlet housing module 1 has better assembly stability and reliability.

[0087] In some possible implementations, reference Figure 1 , Figure 2 and Figure 3 As shown, at least two first fixing structures 23 are provided at the bottom of the volute module 2, and the volute module 2 can be fixedly connected to the front baffle 6 of the vehicle by using the at least two first fixing modules.

[0088] Exemplarily, at least two first fixing structures 23 are respectively arranged on both sides of the bottom of the fan assembly 21 to provide balanced bottom support for the fan assembly 21 .

[0089] Combination Figure 3 and Figure 4 As shown, in some embodiments, the volute module 2 includes a left rudder volute and a right rudder volute; the structures of the left rudder volute and the right rudder volute are bilaterally symmetrical. Figure 3 A left rudder volute is shown. Figure 4 A right rudder volute is shown.

[0090] In order to achieve the universal use of the HVAC system on left-hand drive and right-hand drive vehicles, the volute module 2 of the present embodiment can be divided into a left-hand drive volute and a right-hand drive volute. The structures of the left-hand drive volute and the right-hand drive volute are symmetrical on the left and right, so that the left-hand drive volute can be adapted to left-hand drive vehicles, and the right-hand drive volute can be adapted to right-hand drive vehicles. The structures of the air inlet housing module 1 and the distributor module 3 themselves can be the same, and it is only necessary to adjust their respective assembly positions according to the left and right positions of the fan assembly 21 and the volute body 22 in the left-hand drive volute and the right-hand drive volute.

[0091] In some possible implementations, based on the left rudder volute and the right rudder volute provided in this embodiment, when the air inlet housing module 1 and the distributor module 3 are connected to the left rudder volute, a left rudder HVAC system is formed, such as Figure 1 When the air inlet housing module 1 and the distributor module 3 are connected to the right-hand rudder volute, a right-hand rudder HVAC system is formed, such as Figure 2 As shown, it is suitable for right-hand-drive vehicles. For example, the structures of the air inlet housing module 1 and the distributor module 3 in the left-hand-drive HVAC system and the right-hand-drive HVAC system are exactly the same, but because of the different connection positions with the volute module 2, a left-right symmetrical structure is formed.

[0092] Combination Figures 1 to 8 As shown, in some embodiments, the housing air inlet 101 is located on the front side of the air inlet housing module 1 , and the housing air outlet 102 is located on the bottom surface of the air inlet housing module 1 .

[0093] Through the above arrangement, the housing air inlet 101 is arranged on the front side of the air inlet housing module 1, and the direction of the housing air inlet 101 corresponds to the position of the front baffle 6 of the vehicle, and can be connected to the opening on the front baffle 6, which is conducive to reducing the difficulty of air intake of the HVAC system and improving the air intake efficiency. In addition, the housing air outlet 102 is arranged on the bottom surface of the air inlet housing module 1. When the air inlet housing module 1 is installed on the top of the fan assembly 21, the housing air outlet 102 can be connected to the volute air inlet 201 on the top surface of the fan assembly 21 in a corresponding manner up and down, which has a simple structure and higher reliability.

[0094] Combination Figures 1 to 8 As shown, in some embodiments, the distributor air inlet 301 is located on the front side of the distributor module 3 , and the distributor air outlet 302 is located on the top surface of the distributor module 3 .

[0095] Through the above arrangement, when the distributor module 3 is arranged at the rear side of the volute body 22, the distributor air inlet 301 is connected to the volute air outlet 202 of the volute body 22 in a front-to-rear corresponding manner, which has a simple structure and higher reliability. In addition, the distributor air outlet 302 is arranged on the top surface of the distributor module 3, and can be connected to the internal air outlet channel 71 of the instrument panel 7, and then transported to various air outlets in the vehicle by the internal air outlet channel 71, which is conducive to reducing the difficulty of air outlet of the HVAC system.

[0096] Combination Figure 7 and Figure 8 As shown, in some embodiments, the air inlet housing module 1 further includes a return air port 103 , an internal and external circulation switching component 11 and a filter element component 12 .

[0097] The shell air inlet 101 is used to connect to the vehicle's external air inlet channel, and the return air outlet 103 is used to connect to the vehicle's internal return air channel; the filter element assembly 12 is close to the shell air outlet 102, and the internal and external circulation switching assembly 11 is located on the side of the filter element assembly 12 away from the shell air outlet 102. The internal and external circulation switching assembly 11 is used to switch at least one of the shell air inlet 101 and the return air outlet 103 to be connected to the shell air outlet 102.

[0098] Through the above arrangement, the air inlet housing module 1 can use the internal and external circulation switching component 11 to control the housing air inlet 101 to be connected with the housing air outlet 102, or control the return air port 103 to be connected with the housing air outlet 102. When the housing air inlet 101 is connected with the housing air outlet 102, the outside air can enter through the housing air inlet 101, enter the volute module 2 and the distributor module 3 after passing through the filter element component 12, and finally enter the vehicle interior space, realizing the external circulation of the air inside the vehicle. When the return air port 103 is connected with the housing air outlet 102, the air inside the vehicle can enter through the return air port 103, enter the volute module 2 and the distributor module 3 after passing through the filter element component 12, and finally enter the vehicle interior space, realizing the internal circulation of the air inside the vehicle.

[0099] In some possible implementations, the internal and external circulation switching component 11 includes a flap damper and a driving mechanism. The flap damper is arranged in the air inlet shell module 1. The driving mechanism is connected to the flap damper. The driving structure can drive the flap damper to rotate to open or close the shell air inlet 101, or open or close the return air outlet 103, thereby realizing the switching of internal and external circulation.

[0100] In some possible implementations, the filter element assembly 12 includes filter paper, an activated carbon filter element, a HEPA (high efficiency air filter) air conditioning filter element, and the like.

[0101] In some other possible implementations, the air inlet housing module 1 further includes a fourth fixing structure 13 , which can realize installation and fixation of the air inlet housing module 1 .

[0102] Combination Figure 5 and Figure 6 As shown, in some embodiments, the distributor module 3 includes a refrigerator 31 , a heater 32 , and a damper assembly 33 .

[0103] The damper assembly 33 is close to the air inlet 301 of the distributor, and the refrigerator 31 and the heater 32 are respectively close to the air outlet 302 of the distributor. The damper assembly 33 is used to control the air flow through the refrigerator 31 or the heater 32 .

[0104] Through the above arrangement, the distributor module 3 can use the damper assembly 33 to control the air entering the distributor air inlet 301 to flow through the refrigerator 31 or the heater 32 in a controlled manner. When the air flows through the refrigerator 31, the refrigerator 31 can absorb heat in the air and reduce the temperature of the air. When the air flows through the heater 32, the heater 32 can release heat into the air and increase the temperature of the air, thereby achieving air temperature regulation. The regulated air can be delivered into the vehicle interior space through the distributor air outlet 302 to achieve air regulation of the vehicle interior space.

[0105] In some possible implementations, the distributor module 3 includes a second fixing structure 34 for installing and fixing the distributor module 3 .

[0106] In some possible implementations, the HVAC system also includes a compressor, a throttle valve and a condenser. The outlet of the compressor is connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the expansion valve, the outlet of the expansion valve is connected to the inlet of the refrigerator 31, and the outlet of the refrigerator 31 is connected to the inlet of the compressor. The refrigerator 31 acts as an evaporator, which can absorb heat in the air, reduce the temperature of the air, and achieve air temperature regulation.

[0107] On the other hand, the present embodiment provides a vehicle, and the vehicle includes the HVAC system of the present application.

[0108] The vehicle of this embodiment adopts the HVAC system of the present application and has all the beneficial technical effects of all the embodiments herein.

[0109] In some possible implementations, the vehicle includes but is not limited to a sedan, an SUV, and an MPV, and may be a fuel vehicle, an electric vehicle, or a hybrid vehicle.

[0110] In some other possible implementations, the distributor module 3 is arranged at the middle of the instrument panel 7 , and the air inlet housing module 1 is arranged at a side of the instrument panel 7 corresponding to the co-pilot position.

[0111] Exemplarily, the vehicle may be a left-hand drive vehicle or a right-hand drive vehicle.

[0112] When the vehicle is a left-hand drive vehicle, refer to Fig.10 As shown, the left side of the front fender 6 is the driving position, and the right side is the co-pilot position. At this time, the distributor module 3 is arranged in the middle of the instrument panel 7, and the air intake module is arranged on the right side of the instrument panel 7.
