[0024] The first aspect of this application provides a vehicle HVAC system 10, Figure 1 This is a schematic diagram of a structural embodiment of the vehicle HVAC system 10 provided in this application. Figure 2 yes Figure 1 The diagram shown is a structural illustration from another perspective. Figure 3 yes Figure 1 The diagram shows the structure from another perspective.

[0025] Combination Figure 1 The vehicle HVAC system 10 includes an air conditioning unit 11, a blower 12, and a distribution device 13. The blower 12 is connected to the air conditioning unit 11 to form airflow. The distribution device 13 is connected to the air conditioning unit 11 and the blower 12 to introduce external gas and to distribute and exhaust the airflow.

[0026] Specifically, the air conditioning unit 11 includes a heat exchange device, which is mainly used to exchange heat with the refrigerant in the vehicle's thermal management system, thereby enabling the air conditioning unit 11 to have cooling and heating functions. The blower device 12 may include a blower fan, which generates airflow. The generated airflow comes into contact with the heat exchange device, thereby forming a cold airflow or a warm airflow, thus achieving cooling or heating for the passenger compartment. The generated cold airflow or warm airflow can enter the distribution device 13, which can distribute and discharge the cold airflow or warm airflow.

[0027] Specifically, the distribution device 13 is provided with an air inlet 131 and an air outlet 132. The air inlet 131 is used to introduce outside airflow into the air conditioning unit 11, thereby ultimately forming a cold airflow or a warm airflow. The air outlet 132 is used to exhaust the airflow inside the air conditioning unit 11, that is, to exhaust the cold airflow or warm airflow formed inside the air conditioning unit 11 to the outside. The distribution device 13 may be provided with one or more air inlets 131 or one or more air outlets 132, and the specific configuration can be determined according to actual needs.

[0028] Figure 4 This is a schematic diagram showing the layout of the vehicle's HVAC system 10 at the front of the vehicle.

[0029] Combination Figure 4The vehicle has a front bulkhead 21 extending in the width direction, dividing the vehicle's space into an engine compartment and a passenger compartment arranged in the length direction. The engine compartment houses the engine, front-end cooling structure, etc., while the passenger compartment contains seats for users. The air conditioning unit 11, blower 12, and distribution device 13 are all located on the side of the front bulkhead 21 away from the passenger compartment, within the engine compartment. The distribution device 13 is fitted against the side wall of the front bulkhead 21 so that the air outlet 132 guides airflow through the openings in the front bulkhead 21 into the passenger compartment. The fitting of the distribution device 13 to the front bulkhead 21 facilitates the fixing of the vehicle's HVAC system 10 and the transmission of airflow to the passenger compartment through the air outlet 132.

[0030] It should be understood that when related technologies place the HVAC structure in the passenger compartment of a vehicle, it not only results in significant space occupation and noise, but also requires the condenser pipes from the engine compartment to be routed through the front bulkhead 21 into the HVAC structure within the passenger compartment. This makes the condenser pipes susceptible to compression at locations such as the front bulkhead 21, leading to water leakage. In contrast, the technical solution of this application, because the vehicle HVAC system 10 is located in the engine compartment, does not occupy a large amount of passenger compartment space, nor does its placement in the passenger compartment reduce the vehicle's NVH performance. Furthermore, the condenser pipes can be directly connected from the engine compartment to the vehicle HVAC system 10, thus avoiding compression of the condenser pipes at the front bulkhead 21 and reducing the risk of water leakage due to compression.

[0031] Continue to combine Figures 1-3 In some specific embodiments, the blower 12 and the distributor 13 are disposed on one side of the air conditioning unit 11 in the vehicle width direction, specifically on the left side of the air conditioning unit 11 in the vehicle width direction. The blower 12 and the distributor 13 are arranged at intervals in the vehicle length direction, and the distributor 13 is disposed closer to the passenger compartment than the blower 12.

[0032] Specifically, the length extension direction of the air conditioning unit 11 can be aligned with the length direction of the vehicle. The blower 12 and the distributor 13 can be fitted against the side wall of the air conditioning unit 11 in the width direction of the vehicle, thereby placing the blower 12 and the distributor 13 on one side of the air conditioning unit 11 in the width direction of the vehicle. This allows the blower 12, the distributor 13, and the air conditioning unit 11 to be arranged closely together, thus reducing the overall size of the air conditioning unit 11. The blower 12 and the distributor 13 are spaced apart in the length direction of the vehicle, which reduces the size of the vehicle HVAC system 10 in the width direction, thus facilitating the arrangement of the vehicle HVAC system 10 in the engine compartment. By placing the distributor 13 closer to the passenger compartment than the blower 12, the distributor 13 can be placed closer to the passenger compartment, thus facilitating the introduction of cold or warm air into the passenger compartment.

[0033] Continue to combine Figures 1-3 In some specific embodiments, the air inlet 131 is disposed on the top of the dispensing device 13, and the air outlet 132 is disposed on one side of the dispensing device 13 in the length direction of the vehicle. The air inlet 131 faces the top of the vehicle, and the air outlet 132 faces the side wall of the front bulkhead 21.

[0034] It should be understood that by positioning the air inlet 131 at the top of the distribution device 13 and facing the top of the vehicle, it facilitates the introduction of outside air into the distribution device 13. After the outside air is introduced into the distribution device 13, it is further introduced into the blower 12 and the air conditioning unit 11, ultimately forming a cold or warm airflow. By positioning the air outlet 132 on one side of the distribution device 13 along the length of the vehicle and facing the side wall of the front bulkhead 21, it facilitates the introduction of airflow into the passenger compartment of the vehicle through the front bulkhead 21.

[0035] Continue to combine Figures 1-3 Regarding the specific configuration of the air outlet 132, in some specific embodiments, the air outlet 132 includes a first air outlet 1321 and a second air outlet 1322, which are arranged at intervals in the vehicle height direction. The distribution device 13 can control the airflow to be introduced into the first air outlet 1321 and / or the second air outlet 1322. By setting multiple air outlets 132, different air outlet needs can be met. For example, the first air outlet 1321 can be a face air outlet, and the second air outlet 1322 can be a foot air outlet. By arranging the first air outlet 1321 and the second air outlet 1322 at intervals in the vehicle height direction, the first air outlet 1321 and the second air outlet 1322 can be arranged on one side of the distribution device 13 without affecting each other, which facilitates the outflow of airflow.

[0036] Furthermore, in order to enable the air inlet 131 and the air outlet 132 to filter impurities, a sponge structure can be provided at the air inlet 131 and the air outlet 132 to filter impurities through the sponge structure.

[0037] Figure 5 yes Figure 1 The diagram shown is a structural schematic from its bottom view.

[0038] Combination Figure 5 In some specific embodiments, the vehicle HVAC system 10 also includes a condenser expansion valve 14, which is located at the bottom of the distribution device 13 near the air conditioning unit 11. The condenser expansion valve 14 is connected to the distribution device 13 and is used to connect to the condenser piping in the engine compartment.

[0039] The condenser expansion valve 14 is located on the side of the distribution device 13 closest to the air conditioning unit 11, specifically on the side of the distribution device 13 closest to the air conditioning unit 11 in the vehicle width direction. The bottom of this side is located at the bottom of the distribution device 13 in the vehicle height direction, but the bottom wall of the condenser expansion valve 14 can be higher than the bottom wall of the distribution device 13 in the vehicle height direction. The distribution device 13 contains a condenser pipe that eventually connects to the air conditioning unit 11. The condenser expansion valve 14 is also connected to the distribution device 13, specifically to the condenser pipe within the distribution device 13. At this point, the refrigerant in the condenser pipe in the engine compartment can be introduced into the distribution device 13 through the condenser expansion valve 14, and then further introduced into the air conditioning unit 11.

[0040] Continue to combine Figure 5 In some specific embodiments, the vehicle HVAC system 10 also includes an evaporator expansion valve 15 and a heating water pipe connector 16, both of which are located at the bottom of the distribution device 13 on the side away from the air conditioning unit 11. In conjunction with the above, the distribution device 13 is located on the side away from the air conditioning unit 11 in the vehicle width direction. The evaporator expansion valve 15 and the heating water pipe connector 16 are both connected to the distribution device 13. The evaporator expansion valve 15 is used to connect to the evaporator pipe in the engine compartment, and the heating water pipe connector 16 is used for the input and output of radiator water.

[0041] Specifically, the distribution device 13 is equipped with pipes that are connected to the evaporator expansion valve 15 and the HVAC water pipe connector 16, and these pipes will eventually connect to the relevant pipes inside the air conditioning unit 11. Since the evaporator expansion valve 15 is used to connect to the evaporator pipes inside the engine compartment, the evaporator pipes inside the engine compartment will eventually connect to the relevant pipes inside the air conditioning unit 11 via the evaporator expansion valve 15. Since the HVAC water pipe connector 16 is used for the input and output of radiator water, it enables the input of radiator water into the air conditioning unit 11 and the output of radiator water from the air conditioning unit 11 to the outside.

[0042] A second aspect of this application provides a vehicle front-end structure 20, Figure 6 This is a schematic diagram of one embodiment of the vehicle front-end structure 20 provided in this application. Figure 7 yes Figure 6 Top view of the structure shown. Figure 8 yes Figure 7 Rear view of the structure shown.

[0043] Combination Figures 6-8 The vehicle front structure 20 includes: a vehicle HVAC system 10 as described in any of the above embodiments; a front bulkhead 21 extending along the width direction of the vehicle; and a fixing bracket 22 extending along the width direction of the vehicle. The fixing bracket 22 and the front bulkhead 21 are arranged at intervals along the length direction of the vehicle. The fixing bracket 22 and the front bulkhead 21 are connected to the vehicle HVAC system 10 to fix the vehicle HVAC system 10.

[0044] It should be understood that when the front bulkhead 21 extends in the width direction of the vehicle, it divides the vehicle space into the engine compartment and the passenger compartment. At this time, the fixing bracket 22 is closer to the front end of the vehicle in the length direction than the front bulkhead 21. At this time, the fixing bracket 22 and the front bulkhead 21 can be fixedly connected to both ends of the vehicle HVAC system 10 in the length direction of the vehicle, thereby achieving a good fixing effect on the vehicle HVAC system 10.

[0045] Regarding the specific configuration of the front bulkhead 21, combined with Figure 8 In some specific embodiments, the front bulkhead 21 is provided with a ventilation opening 211, which is used to communicate with the air outlet 132 so that the airflow from the air outlet 132 is introduced into the passenger compartment through the ventilation opening 211. The ventilation opening 211 facilitates the direct transmission of airflow from the air outlet 132 into the passenger compartment through the front bulkhead 21.

[0046] Regarding the specific arrangement of the fixed bracket 22, in some specific embodiments, the fixed bracket 22 includes an upper crossbar 221 and a lower crossbar 222. The upper crossbar 221 is connected to the lower crossbar 222 and is located above the lower crossbar 222. The upper crossbar 221 is connected to the blower 12 and the air conditioning unit 11, and the lower crossbar 222 is also connected to the blower 12 and the air conditioning unit 11.

[0047] Specifically, the vehicle HVAC system 10 includes connecting brackets 17. Connecting brackets 17 can be provided on the outer walls of the air conditioning unit 11, the blower 12, and the distribution device 13, thus the vehicle HVAC system 10 includes multiple connecting brackets 17. The upper crossbar 221 is connected to the blower 12 and the air conditioning unit 11 via connecting brackets 17, and the lower crossbar 222 is also connected to the blower 12 and the air conditioning unit 11 via connecting brackets 17. By providing two parts, upper and lower, the fixing brackets 22 can effectively secure the vehicle HVAC system 10 in the vehicle's height direction.

[0048] A third aspect of this application provides a vehicle including a vehicle HVAC system 10 as described in any of the above embodiments, or a vehicle front-end structure 20 as described in any of the above embodiments. Specific descriptions of the vehicle HVAC system 10 and the vehicle front-end structure 20 can be found in the relevant descriptions of the above embodiments, and will not be repeated here.

[0049] In summary, based on the vehicle HVAC system 10, vehicle front-end structure 20, and vehicle provided in this application, the vehicle HVAC system 10 includes: an air conditioning unit 11; a blower 12 connected to the air conditioning unit 11 for generating airflow; and a distribution device 13 connected to the air conditioning unit 11 and the blower 12. The distribution device 13 is provided with an air inlet 131 and an air outlet 132. The air inlet 131 is used to introduce external airflow into the air conditioning unit 11, and the air outlet 132 is used to discharge the airflow from the air conditioning unit 11. The air conditioning unit 11, the blower 12, and the distribution device 13 are all located on the side of the front bulkhead 21 away from the passenger compartment, within the engine compartment. The distribution device 13 is fitted against the side wall of the front bulkhead 21 so that the air outlet 132 can guide airflow through the through-hole of the front bulkhead 21 into the passenger compartment. Therefore, by placing the main structure of the vehicle HVAC system 10 in the engine compartment and directing airflow into the passenger compartment through the front bulkhead 21, the space occupied by the passenger compartment and the noise caused to the passenger compartment can be significantly reduced, and the risk of water leakage from the condenser pipe can be reduced.

[0050] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
