Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to an air intake structure, an air conditioning unit, and a vehicle. Background Technology

[0002] With social progress, automobiles are gradually developing towards greater universality and diversification, and the comfort of automobiles has gradually become a focus of people's attention.

[0003] Currently, most automotive air conditioning units on the market adopt a dual-layer flow energy-saving air intake mode, which can achieve environmental protection, energy saving, safety and stability, and energy saving. The dual-layer flow energy-saving air intake mode air conditioning unit is gradually becoming the mainstream design.

[0004] However, the existing dual-flow air conditioning units on the market have problems such as small impeller diameter-to-height ratio, poor vibration and noise performance, and large space occupation, which is not conducive to the space layout inside the car. Summary of the Invention

[0005] The purpose of this application is to provide an air intake structure, an air conditioning unit, and a vehicle that can reduce the vibration and noise generated by the air conditioning unit, reduce the installation space required, and improve comfort.

[0006] The first aspect of this application provides an air intake structure, including:

[0007] An air intake assembly includes a volute and a rotating component. The volute has an air inlet and an air outlet that are connected to each other. The rotating component is disposed inside the volute and corresponds to the air inlet. The rotating component can rotate inside the volute to drive the gas from the air inlet to the air outlet. A baffle is disposed inside the volute and extends along the gas flow direction, and the baffle is spaced apart from the rotating component; A first gas flow channel is formed between the rotating component and the partition plate, and a second gas flow channel is formed between the rotating component and the inner wall of the volute. The first gas flow channel and the second gas flow channel are centrally symmetrical about the center of the rotating component.

[0008] In one exemplary embodiment of this application, the partition is disposed around a portion of the outer edge of the rotating member on the side near the rotating member; The partition has a first surface and a second surface. The first surface is located on the side of the partition closer to the rotating member, and the second surface is located on the side of the partition away from the rotating member. The first surface and the rotating member form a first gas flow channel, and the second surface and the inner wall of the volute form a third gas flow channel. Both the first gas flow channel and the third gas flow channel are connected to the air outlet. The inner wall of the volute opposite to the rotating component forms a second gas flow channel with the rotating component.

[0009] In one exemplary embodiment of this application, the volute includes a body and a first volute tongue, the first volute tongue being disposed on the side of the body near the air outlet and spaced apart from the rotating member; The air intake structure also includes a second volute tongue, which protrudes from the side of the partition near the rotating member. The second volute tongue is spaced apart from the rotating member, and the second volute tongue and the first volute tongue are centrally symmetrical about the center of the rotating member.

[0010] In one exemplary embodiment of this application, the distance between the second volute tongue and the center of the rotating member gradually increases in the gas flow direction.

[0011] In one exemplary embodiment of this application, the air inlet structure further includes a fourth gas flow channel, which connects the first gas flow channel and the air outlet; In the direction of gas flow, the cross-sectional areas of the third gas flow channel and the fourth gas flow channel gradually increase.

[0012] In one exemplary embodiment of this application, the first gas flow channel and the third gas flow channel are arranged sequentially in the radial direction of the rotating member.

[0013] A second aspect of this application provides an air conditioning unit, the air conditioning unit comprising: The air inlet box unit has an internal circulation air inlet channel and an external circulation air inlet channel. The internal circulation air inlet channel has an internal circulation air inlet and an internal circulation air outlet. The external circulation air inlet channel has an external circulation air inlet and an external circulation air outlet. The internal circulation air inlet and the external circulation air inlet are spaced apart. The internal circulation air outlet and the external circulation air outlet are also spaced apart. The distribution box unit has an inlet, a first outlet, and a second outlet that are spaced apart from each other. In any of the above-mentioned air intake structures, the air inlet of the air intake structure is connected to the internal circulation air outlet and the external circulation air outlet, and the air outlet of the air intake structure is connected to the inlet of the distribution box unit; The gas at the internal circulation outlet flows into the second gas channel under the action of the rotating component; the gas at the external circulation outlet flows into the first gas channel under the action of the rotating component. Gas passing through the first gas channel flows out from the first outlet, and gas passing through the second gas channel flows out from the second outlet.

[0014] In another exemplary embodiment of this application, the air conditioning unit further includes an isolation plate disposed at the internal circulation air outlet and the external circulation air outlet to separate the internal circulation air outlet and the external circulation air outlet.

[0015] In another exemplary embodiment of this application, the distribution box unit further includes an evaporator core and a warm air core, the evaporator core and the warm air core being arranged sequentially in the gas flow direction, and the evaporator core and the warm air core being spaced apart; The distribution box unit includes a first flow chamber and a second flow chamber, wherein the first flow chamber is connected to the first gas flow channel and the second flow chamber is connected to the second gas flow channel; The evaporator core is located in the first flow chamber and the other part is located in the second flow chamber; the heater core is located in the first flow chamber and the other part is located in the second flow chamber.

[0016] A third aspect of this application provides a vehicle including the air conditioning unit described in any of the preceding claims.

[0017] The proposed solution has the following beneficial effects: This application includes an air intake structure, an air conditioning unit, and a vehicle. The air intake structure includes an air intake assembly and a baffle. The air intake assembly includes a volute and a rotating component. The rotating component and the baffle are both located inside the volute. The rotating component, the baffle, and the inner wall of the volute are spaced apart, and the rotating component can rotate within the volute to drive gas from the air inlet to the air outlet. Since the rotating component forms a first gas flow channel and a second gas flow channel with respect to the inner wall of the volute and the baffle, respectively, and the first and second gas flow channels are symmetrical with respect to the center of the rotating component, the fluid pressure and turbulent kinetic energy, and other fluid dynamic parameters, experienced by the rotating component in the first and second gas flow channels are similar. This results in the reaction force experienced by the rotating component in the first gas flow channel and the reaction force experienced in the second gas flow channel being concentrated in the same direction, which can reduce the operational imbalance and surge of the rotating component, reduce the vibration and noise of the air intake structure, and thus reduce the vibration and noise generated by the air conditioning unit and the vehicle.

[0018] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0027] Example 1 This application provides an air intake structure 100, which can be applied to the air conditioning unit 10 in a vehicle or in other environments, without specific limitations.

[0028] Among them, see Figure 1 or Figure 2 As shown, this air intake structure 100 includes: An air intake assembly 101 includes a volute 110 and a rotating member 111. The volute 110 has an air inlet 112 and an air outlet 113 that are interconnected. The volute 110 also has a receiving cavity corresponding to the air inlet 112. The receiving cavity houses the rotating member 111, which can rotate within the receiving cavity, generating negative pressure at the air inlet 112 and positive pressure at the air outlet 113 to provide airflow power, thereby driving the air at the air inlet 112 to flow from the air inlet 112 to the air outlet 113. Figure 1 As shown.

[0029] A baffle 102 is disposed inside the volute 110 and connected to the two opposing inner sidewalls of the volute 110. The baffle 102 extends along the gas flow direction and is spaced apart from the rotating member 111. Figure 1 As shown.

[0030] Among them, see Figure 2 As shown, a first gas flow channel 103 is formed between the rotating member 111 and its corresponding partition 102, and the rotating member 111 can drive gas to flow out of the first gas flow channel 103; a second gas flow channel 104 is formed between the rotating member 111 and its corresponding inner wall of the volute 110, and the rotating member 111 can drive gas to flow out of the second gas flow channel 104. The first gas flow channel 103 and the second gas flow channel 104 are centrally symmetrically distributed about the center of the rotating member 111.

[0031] It is understandable that, since the first gas flow channel 103 and the second gas flow channel 104 are symmetrical about the center of the rotating member 111, the fluid pressure, turbulent kinetic energy and other fluid dynamic parameters in the first gas flow channel 103 and the second gas flow channel 104 are similar. Therefore, the reaction force exerted by the gas on the rotating member 111 in the first gas flow channel 103 and the second gas flow channel 104 is also symmetrical about the center. This can reduce the force on the rotating member 111, reduce the actuation imbalance and surge of the rotating member 111, and thus reduce the vibration and noise generated by the air intake structure 100 when conveying gas.

[0032] In other words, the present application solution forms a first gas flow channel 103 and a second gas flow channel 104 at the two centrally symmetrical ends of the rotating component 111, so that the reaction force on the rotating component 111 is centrally symmetrical, which can reduce the actuation imbalance and surge of the rotating component 111, thereby reducing the vibration and noise generated by the air intake structure 100 when conveying gas, and improving the overall comfort.

[0033] In one possible embodiment of this application, the rotating component 111 may be an impeller, and a motor 105 may be provided on the side opposite to the air inlet 112 in the volute 110, such as... Figure 3 As shown. The motor 105 is electrically connected to the impeller. Under the control of the motor 105, the impeller can rotate in a preset direction and speed, thereby generating negative pressure at the air inlet 112 and positive pressure at the air outlet 113 of the volute 110, providing airflow power so that the gas flows from the air inlet 112 to the air outlet 113.

[0034] In one possible embodiment of this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, a portion of the partition 102 is disposed within this receiving cavity and surrounds a portion of the outer edge of the rotating member 111, that is, the partition 102 and the rotating member 111 have corresponding portions, and are approximately concentric. The partition 102 surrounding the rotating member 111 is spaced apart from the rotating member 111. The partition 102 has a first surface and a second surface. The first surface is located on the side of the partition 102 closest to the rotating member 111, forming a first gas flow channel 103 between the first surface and the rotating member 111. The second surface is located on the side of the partition 102 away from the rotating member 111, forming a third gas flow channel 106 with the inner wall of the volute 110. The gas introduced by the rotating member 111 through the air inlet 112 can flow out through the first gas flow channel 103 or the second gas flow channel 104, and the second gas flow channel 104 and the third gas flow channel 106 are interconnected. Figure 2 As shown.

[0035] Among them, such as Figure 1As shown, the present application also includes a fourth gas flow channel 107. The first gas flow channel 103 is connected to the air outlet through the fourth gas flow channel 107. The first gas flow channel 103 and the third gas flow channel 106 are arranged sequentially in the radial direction of the rotating member 111. By designing the airflow separation in the radial direction of the rotating member 111, a dual-layer flow energy-saving air intake mode can be realized. Moreover, by adopting the radial separation design, the rotating member 111 can achieve a larger diameter-to-height ratio, reducing the vibration and noise generated during operation.

[0036] Furthermore, in the gas flow direction, the cross-sectional areas of the first gas channel 103, the second gas channel 104, the third gas channel 106, and the fourth gas channel 107 gradually increase, thereby gradually reducing the gas velocity and increasing the gas flow rate. That is, in the gas flow direction, the flow rates of the first gas channel 103, the second gas channel 104, the third gas channel 106, and the fourth gas channel 107 gradually increase to reduce the gas flow rate.

[0037] In one possible embodiment of this application, please continue to refer to Figure 1 As shown, the volute 110 includes a body 114 and a first volute tongue 115. The body 114 is provided with an air inlet 112, an air outlet 113, and the aforementioned receiving cavity. The first volute tongue 115 is located on the side of the body 114 near the air outlet 113, and is spaced apart from the rotating member 111. The air inlet structure 100 also includes a second volute tongue 108, which protrudes from the partition 102 on the side near the rotating member 111 and is spaced apart from the rotating member 111. The second volute tongue 108 and the first volute tongue 115 are centrally symmetrical about the center of the rotating member 111.

[0038] It is understandable that by using the double volute structure of the first volute tongue 115 and the second volute tongue 108, and by adjusting the distance between the double volute tongue and the center of the rotating part 111, as well as the position of the double volute tongue, it is possible to reduce gas leakage in the second gas flow channel 104 and the first gas flow channel 103 caused by the volute tongue, while also reducing vibration and noise caused by the excessively close distance between the volute tongue and the center of the rotating part 111, thereby achieving a balance between low leakage rate and vibration and noise.

[0039] The first volute tongue 115 is at a first distance from the center of the rotating member 111, and the second volute tongue 108 is at a second distance from the center of the rotating member 111. The first distance and the second distance are equal to ensure that the air leakage rate caused by the volute tongue is reduced and the vibration and noise generated are reduced.

[0040] In one possible embodiment of this application, see [link to relevant documentation]. Figure 1As shown, in the direction of gas flow, the distance between the second volute tongue 108 and the center of the rotating member 111 gradually increases. This not only guides the gas flow but also reduces the gas leakage rate at the second volute tongue 108, preventing gas in the second gas channel 104 from leaking into the first gas channel 103, and also preventing gas in the first gas channel 103 from leaking into the second gas channel 104.

[0041] It is worth mentioning that this partition 102 separates the first gas flow channel 103 and the third gas flow channel 106 in the radial direction of the rotating member 111. That is, the first gas flow channel 103 and the third gas flow channel 106 are arranged sequentially in the radial direction of the rotating member 111. See Figure 4 As shown, this airflow separation design achieves a dual-layer flow energy-saving air intake mode. Furthermore, the first gas flow channel 103 and the third gas flow channel 106 adopt a radial separation design, allowing the rotating component 111 to achieve a larger diameter-to-height ratio, reducing vibration and noise during operation, thereby reducing the vibration and noise of the air intake structure 100.

[0042] In addition, the radially partitioned design can reduce the volume of the air intake structure 100, thus requiring less installation space.

[0043] It should be noted that when this air intake structure 100 is applied to the air conditioning unit 10 of a vehicle, the air intake structure 100 is interconnected with the air intake box unit 200 and the distribution box unit 300 on the air conditioning unit 10. For example, the air intake box unit 200, the air intake structure 100, and the distribution box unit 300 are assembled together using fasteners such as clips and screws to ensure that the air intake box unit 200, the air intake structure 100, and the distribution box unit 300 do not wobble relative to each other. Figure 5 and Figure 6 As shown.

[0044] Among them, see Figure 7 and Figure 8 As shown, the air intake unit 200 has an internal circulation air intake channel and an external circulation air intake channel. The internal circulation air intake channel has an internal circulation inlet 201 and an internal circulation outlet 202, and the external circulation air intake channel has an external circulation inlet 203 and an external circulation outlet 204. The internal circulation inlet 201 and the external circulation inlet 203 are spaced apart from each other, and the internal circulation outlet 202 and the external circulation outlet 204 are spaced apart from each other. In other words, this air conditioning unit 10 has two circulation channels, internal circulation and external circulation, which are separated from each other and do not interfere with each other, and the air flows out from their respective circulation outlets.

[0045] In addition, see Figure 7As shown, in order to adjust the channel size of the internal circulation air intake channel and the external circulation air intake channel, this air intake box unit 200 also includes an air intake body 205 and a circulation damper 206. The circulation damper 206 is disposed on the air intake body 205 and can adjust the channel size of the internal circulation air intake channel and the external circulation air intake channel.

[0046] It is worth mentioning that the internal circulation outlet 202 and the external circulation outlet 204 are connected to the air inlet 112 of the air inlet structure 100; that is, the gas in the internal circulation outlet 202 and the gas in the external circulation outlet 204 can flow into the volute 110 through the air inlet 112 in the air inlet structure 100.

[0047] See Figure 9 and Figure 10 As shown, the distribution box unit 300 has an inlet 301, a first outlet 302 and a second outlet 303 arranged at intervals. The first outlet 302 has two gas flow channels, one of which can be a front blowing gas flow channel 320 and the other can be a defrosting gas flow channel 321. The second outlet 303 can be a front blowing foot vent.

[0048] Among them, see Figure 11 As shown, the inlet 301 of the distribution box unit 300 is connected to the outlet 113 of the air intake structure 100. Gas at the internal circulation outlet 202 flows into the third gas flow channel 106 under the influence of the rotating component 111, while gas at the external circulation outlet 204 flows into the first gas flow channel 103 under the influence of the rotating component 111. In other words, the air intake structure 100 can separate the gas in the internal and external circulation air intake channels, achieving a dual-layer flow energy-saving air intake mode and reducing the vehicle's energy consumption. Furthermore, this air intake structure 100 can also reduce vibration and noise and improve space utilization.

[0049] Understandably, to prevent mixing of gases when they enter the internal and external circulation air intake ducts simultaneously, this air conditioning unit 10 is also equipped with an isolation plate 400, such as... Figure 8 As shown. This isolation plate 400 is disposed at the internal circulation air inlet 201 and the external circulation air inlet 203 to separate the gas in the internal circulation air inlet channel and the external circulation air inlet channel, so that the gas in the internal circulation air inlet channel and the gas in the external circulation air inlet channel flow into the second gas flow channel 104 and the first gas flow channel 103 respectively. Furthermore, the double volute structure of the first volute tongue 115 and the second volute tongue 108 can reduce the gas leakage rate between the internal and external gases, and can also reduce vibration and noise, thereby achieving a balance between low gas leakage rate and vibration and noise.

[0050] It should be noted that, through the design of the fluid dynamics model, this isolation plate 400 is set at the internal circulation air outlet 202 and the external circulation air outlet 204, so that the air inside the vehicle and the air outside the vehicle can enter the air inlet 112 at a specific angle, and then, driven by the rotating part 111, can enter the second gas flow channel 104 and the first gas flow channel 103 respectively, without air mixing between them.

[0051] In one possible embodiment of this application, see [link to relevant documentation]. Figure 9 As shown, the distribution box unit 300 also includes an evaporator core 304 and a heater core 305, which are arranged sequentially in the gas flow direction, i.e., the evaporator core 304 is closer to the inlet 301 of the distribution box unit 300 than the heater core 305. Furthermore, this distribution box unit 300 also includes a first flow chamber 306 and a second flow chamber 307. The first flow chamber 306 is connected to the first gas flow channel 103, i.e., the first flow chamber 306 is connected to the first gas flow through the fourth gas flow channel 107; the second flow chamber 307 is connected to the third gas flow channel 106. A portion of the evaporator core 304 is located in the first flow chamber 306, and another portion is located in the second flow chamber 307; a portion of the heater core 305 is located in the first flow chamber 306, and another portion is located in the second flow chamber 307.

[0052] In one possible embodiment of this application, see [link to relevant documentation]. Figure 11 As shown, half of the evaporator core 304 is located in the first flow chamber 306 and the other half is located in the second flow chamber 307. Half of the warm air core 305 is located in the first flow chamber 306 and the other half is located in the second flow chamber 307.

[0053] It is understandable that by using this partition 102 to radially separate the first gas flow channel 103 and the third gas flow channel 106, the third gas flow channel 106 and the fourth gas flow channel 107 in the air inlet structure 100 are centrally layered, which makes the gas flow rate and gas velocity in the first flow chamber 306 and the second flow chamber 307 of the evaporator core 304 approximately the same, ensuring good uniformity of the flow velocity on the surface of the evaporator core 304.

[0054] Furthermore, this radially separated design ensures uniform flow velocity on the surface of the evaporator core 304 while allowing for greater flexibility in the position of the air intake structure 100 relative to the distribution box unit 300, which is beneficial for the overall vehicle layout.

[0055] The dual-layer flow energy-saving mode of this application is implemented as follows: The motor 105 drives the rotating component 111 to rotate inside the volute 110, which generates negative pressure at the air inlet 112 and positive pressure at the air outlet 113.

[0056] See Figure 11 As indicated by the dark arrow, the gas inside the vehicle flows into the internal circulation intake channel through the internal circulation intake port 201, and then into the air inlet 112 through the internal circulation outlet 202. The gas enters the air inlet 112 at a specific angle through the baffle plate 400. As the rotating part 111 rotates in the receiving cavity, the internal gas rotates at a certain angle and flows into the second gas flow channel 104. Then, it is separated by the baffle plate 102 so that the internal gas flows into the third gas flow channel 106. Then, it flows out from the air outlet 113 through the third gas flow channel 106 and finally enters the distribution box unit 300. The internal gas flows out from the second outlet 303 through the evaporator core 304 or the heater core, that is, it flows out from the front foot vent.

[0057] See Figure 11 As indicated by the gray arrow, external air flows into the external air intake channel through the external air intake port 203, and then into the air intake port 112 through the external air outlet 204. The gas is guided into the air intake port 112 at a specific angle by the baffle plate 400. As the rotating component 111 rotates in the receiving cavity, the external gas rotates at a certain angle and flows into the first gas flow channel 103. After being guided by the baffle plate 102, this external gas is introduced into the fourth gas flow channel 107, and then flows out from the air outlet 113 through the fourth gas flow channel 107. Finally, it enters the distribution box unit 300. The external gas flows out from the first outlet 302 through the evaporator core 304 or the heater core; that is, from the front blowing gas flow channel 320 and the defrosting gas flow channel 321, for blowing and defrosting.

[0058] See Figure 11 As indicated by the dark and gray arrows, when gases from inside and outside the vehicle simultaneously enter the internal and external circulation intake channels, the isolation plate 400 separates the gases from the gases outside the vehicle, and they enter the rotating component 111 in layers at a specific angle. When the rotating component 111 rotates, the gases inside the vehicle will flow out from the air outlet 113 along the second gas flow channel 104 and the third gas flow channel 106, and the gases outside the vehicle will flow out from the air outlet 113 along the first gas flow channel 103 and the fourth gas flow channel 107, and then enter the second flow chamber 307 and the first flow chamber 306 respectively.

[0059] Understandably, the gas is cooled down after passing through the evaporator core 304, and heated after passing through the heater core.

[0060] The present application solution can reduce the vibration and noise generated by the rotating component 111 during gas conveying through the aforementioned air inlet structure 100; in addition, the double volute structure can also achieve a balance between low gas leakage rate and vibration and noise. Moreover, through the radial separation design, the rotating component 111 can achieve a large diameter-to-height ratio, reducing vibration and noise during operation, and the air inlet structure 100 is small in size, requiring little installation space.

[0061] Example 2 Embodiment 2 of this application provides an air conditioning unit 10, which includes an air inlet box unit 200, a distribution box unit 300, and an air inlet structure 100 as described in Embodiment 1, such as... Figure 5 or Figure 6 As shown.

[0062] The air inlet box unit 200, the air inlet structure 100 and the distribution box unit 300 are assembled together by fasteners such as buckles and screws to ensure that the air inlet box unit 200, the air inlet structure 100 and the distribution box unit 300 do not shake with each other.

[0063] Among them, see Figure 7 and Figure 11 As shown, the air intake unit 200 has an internal circulation air intake channel and an external circulation air intake channel. The internal circulation air intake channel has an internal circulation inlet 201 and an internal circulation outlet 202, and the external circulation air intake channel has an external circulation inlet 203 and an external circulation outlet 204. The internal circulation inlet 201 and the external circulation inlet 203 are spaced apart from each other, and the internal circulation outlet 202 and the external circulation outlet 204 are spaced apart from each other. In other words, this air conditioning unit 10 has two circulation channels, internal circulation and external circulation, which are spaced apart from each other to avoid interference, and the air flows out from their respective circulation outlets.

[0064] In addition, to adjust the channel size of the internal and external circulation air intake channels, this air intake box unit 200 also includes an air intake body 205 and a circulation damper 206. The circulation damper 206 is located on the air intake body 205 and can adjust the channel size of the internal and external circulation air intake channels. Figure 7 As shown.

[0065] It is worth mentioning that the internal circulation outlet 202 and the external circulation outlet 204 are connected to the air inlet 112 of the air inlet structure 100; that is, the gas in the internal circulation outlet 202 and the gas in the external circulation outlet 204 can flow into the volute 110 through the air inlet 112 of the air inlet structure 100, such as... Figure 11 As shown.

[0066] See Figure 10As shown, the distribution box unit 300 has an inlet 301, a first outlet 302 and a second outlet 303 arranged at intervals. The first outlet 302 has two gas flow channels, one of which can be a front blowing gas flow channel 320 and the other can be a defrosting gas flow channel 321. The second outlet 303 can be a front blowing foot vent.

[0067] In this design, the inlet 301 of the distribution box unit 300 is connected to the outlet 113 of the air intake structure 100. Gas at the internal circulation outlet 202 flows into the third gas flow channel 106 under the influence of the rotating component 111, while gas at the external circulation outlet 204 flows into the first gas flow channel 103 under the influence of the rotating component 111. In other words, the air intake structure 100 can separate the gas in the internal and external circulation air intake channels, achieving a dual-layer flow energy-saving air intake mode and reducing the vehicle's overall energy consumption. Furthermore, this air intake structure 100 can also reduce vibration and noise and improve space utilization.

[0068] Understandably, to prevent mixing of gases when they enter the internal and external circulation air intake ducts simultaneously, this air conditioning unit 10 is also equipped with an isolation plate 400, such as... Figure 8 As shown. This isolation plate 400 is disposed at the internal circulation air inlet 201 and the external circulation air inlet 203 to separate the gas in the internal circulation air inlet channel and the external circulation air inlet channel, so that the gas in the internal circulation air inlet channel and the gas in the external circulation air inlet channel flow into the second gas flow channel 104 and the first gas flow channel 103 respectively. Furthermore, the double volute structure of the first volute tongue 115 and the second volute tongue 108 can reduce the gas leakage rate between the internal and external gases, and can also reduce vibration and noise, thereby achieving a balance between low gas leakage rate and vibration and noise.

[0069] It should be noted that, through the design of the fluid dynamics model, this isolation plate 400 is set at the internal circulation air outlet 202 and the external circulation air outlet 204, so that the air inside the vehicle and the air outside the vehicle can enter the air inlet 112 at a specific angle, and then, driven by the rotating part 111, can enter the second gas flow channel 104 and the first gas flow channel 103 respectively, without air mixing between them.

[0070] In one possible embodiment of this application, see [link to relevant documentation]. Figure 11As shown, the distribution box unit 300 also includes an evaporator core 304 and a heater core 305, which are arranged sequentially in the gas flow direction, i.e., the evaporator core 304 is closer to the inlet 301 of the distribution box unit 300 than the heater core 305. Furthermore, this distribution box unit 300 also includes a first flow chamber 306 and a second flow chamber 307. The first flow chamber 306 is connected to the first gas flow channel 103, i.e., the first flow chamber 306 is connected to the first gas flow through the fourth gas flow channel 107; the second flow chamber 307 is connected to the third gas flow channel 106. A portion of the evaporator core 304 is located in the first flow chamber 306, and another portion is located in the second flow chamber 307; a portion of the heater core 305 is located in the first flow chamber 306, and another portion is located in the second flow chamber 307.

[0071] In one possible embodiment of this application, please continue to refer to Figure 11 As shown, half of the evaporator core 304 is located in the first flow chamber 306 and the other half is located in the second flow chamber 307. Half of the warm air core 305 is located in the first flow chamber 306 and the other half is located in the second flow chamber 307.

[0072] It is understandable that by using this partition 102 to radially separate the first gas flow channel 103 and the third gas flow channel 106, the third gas flow channel 106 and the fourth gas flow channel 107 in the air inlet structure 100 are centrally layered, which makes the gas flow rate and gas velocity in the first flow chamber 306 and the second flow chamber 307 of the evaporator core 304 approximately the same, ensuring good uniformity of the flow velocity on the surface of the evaporator core 304.

[0073] Furthermore, this radially separated design ensures uniform flow velocity on the surface of the evaporator core 304 while allowing for greater flexibility in the position of the air intake structure 100 relative to the distribution box unit 300, which is beneficial for the overall vehicle layout.

[0074] The dual-layer flow energy-saving mode of this application is implemented as follows: The motor 105 drives the rotating component 111 to rotate inside the volute 110, which generates negative pressure at the air inlet 112 and positive pressure at the air outlet 113.

[0075] See Figure 11As indicated by the dark arrow, the gas inside the vehicle flows into the internal circulation intake channel through the internal circulation intake port 201, and then into the air inlet 112 through the internal circulation outlet 202. The gas enters the air inlet 112 at a specific angle through the baffle plate 400. As the rotating part 111 rotates in the receiving cavity, the internal gas rotates at a certain angle and flows into the second gas flow channel 104. Then, it is separated by the baffle plate 102 so that the internal gas flows into the third gas flow channel 106. Then, it flows out from the air outlet 113 through the third gas flow channel 106 and finally enters the distribution box unit 300. The internal gas flows out from the second outlet 303 through the evaporator core 304 or the heater core, that is, it flows out from the front foot vent.

[0076] See Figure 11 As indicated by the gray arrow, external air flows into the external air intake channel through the external air intake port 203, and then into the air intake port 112 through the external air outlet 204. The gas is guided into the air intake port 112 at a specific angle by the baffle plate 400. As the rotating component 111 rotates in the receiving cavity, the external gas rotates at a certain angle and flows into the first gas flow channel 103. After being guided by the baffle plate 102, this external gas is introduced into the fourth gas flow channel 107, and then flows out from the air outlet 113 through the fourth gas flow channel 107. Finally, it enters the distribution box unit 300. The external gas flows out from the first outlet 302 through the evaporator core 304 or the heater core; that is, from the front blowing gas flow channel 320 and the defrosting gas flow channel 321, for blowing and defrosting.

[0077] See Figure 11 As indicated by the dark and gray arrows, when gases from inside and outside the vehicle simultaneously enter the internal and external circulation intake channels, the isolation plate 400 separates the gases from the gases outside the vehicle, and they enter the rotating component 111 in layers at a specific angle. When the rotating component 111 rotates, the gases inside the vehicle will flow out from the air outlet 113 along the second gas flow channel 104 and the third gas flow channel 106, and the gases outside the vehicle will flow out from the air outlet 113 along the first gas flow channel 103 and the fourth gas flow channel 107, and then enter the second flow chamber 307 and the first flow chamber 306 respectively.

[0078] Understandably, the gas is cooled down after passing through the evaporator core 304, and heated after passing through the heater core.

[0079] The present application solution can reduce the vibration and noise generated by the rotating component 111 during gas conveying through the aforementioned air inlet structure 100; in addition, the double volute structure can also achieve a balance between low gas leakage rate and vibration and noise. Moreover, through the radial separation design, the rotating component 111 can achieve a large diameter-to-height ratio, reducing vibration and noise during operation, and the air inlet structure 100 is small in size, requiring little installation space.

[0080] In other words, the air conditioning unit 10 achieves a centrally located dual-layer flow energy-saving air intake mode, which reduces energy consumption for the whole vehicle while reducing vibration and noise. The air conditioning unit 10 requires little installation space.

[0081] Example 3 This application provides a vehicle in embodiment three, which includes the air conditioning unit 10 from embodiment two, as shown below. Figure 5 or Figure 6 As shown. This air conditioning unit 10 can achieve a dual-layer flow energy-saving air intake mode, which reduces the energy consumption of the whole vehicle, while also reducing vibration and noise. The air conditioning unit 10 requires little installation space, increasing the space utilization of the vehicle.
