[0039] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] The air conditioning system of a heavy-duty vehicle includes an air intake system. The air intake system can supply air from the outside environment to the evaporator in the air conditioning system to achieve external circulation, and it can also supply air from the passenger compartment to the evaporator in the air conditioning system to achieve internal circulation.

[0042] The intake system typically uses a rotating damper to open and close the external circulation channel. However, when the damper closes the external circulation channel by rotating, there is often a gap between the damper and the external circulation channel.

[0043] The aforementioned gaps can easily allow dust to enter and clog the filter element inside the evaporator, affecting the air volume of the air conditioning system and causing air leakage in the air conditioning system.

[0044] The automotive air conditioning evaporator intake system and vehicle provided in this application utilize a sealing component that effectively seals the gap between the sealing component and the side wall of the intake passage. This significantly improves the airtightness of the intake passage, preventing dust and moisture from the external environment from seeping into the evaporator and clogging the evaporator filter, thereby reducing the airflow volume required for internal recirculation in the air conditioning system. Furthermore, because the gap between the sealing component and the side wall of the intake passage is sealed, air leakage is prevented during internal recirculation of the air conditioning system. When external air enters the intake passage through the intake port, it flows along the axial direction of the intake port and collides with the side wall of the intake passage, effectively separating dust and moisture from the airflow and preventing them from affecting the operation of the evaporator.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] Firstly, such as Figures 1-2 and Figure 4As shown in the figure, this application embodiment provides an air intake system for a vehicle air conditioning evaporator, including a housing 100. An air intake channel 110 is formed inside the housing 100, and the air intake channel 110 has two openings on the housing 100, namely an inlet end 111 and an outlet end 112. The housing 100 is connected to the evaporator 200 in the air conditioning system, and the housing 100 is specifically connected to the air intake side of the evaporator 200, so that the outlet end 112 of the air intake channel 110 can be connected to the air intake channel of the evaporator 200, so that air from the external environment can be supplied to the evaporator 200 sequentially through the inlet end 111 and the outlet end 112 of the air intake channel 110, thereby realizing the temperature regulation of the driver's cab by the air conditioning system.

[0047] Furthermore, such as Figures 3-4 As shown, a sealing element 300 is also provided in the air intake passage 110. The sealing element 300 is movable in the air intake passage 110, allowing it to open and close the air intake passage 110 by moving within it. When the air conditioning system needs to draw air from the external environment, the sealing element 300 opens the air intake passage 110; when the air conditioning system does not need to draw air from the external environment, the sealing element 300 closes the air intake passage 110.

[0048] The vehicle air conditioning evaporator intake system of this application embodiment has a sealing element provided on at least one of the intake passage 110 and the sealing element 300. Specifically, when the sealing element is provided in the intake passage 110, it is located on the side wall of the intake passage 110; when the sealing element is provided on the sealing element 300, it is located on the circumferential side of the sealing element 300. When the sealing element 300 closes the intake passage 110 by movement, the circumferential side of the sealing element 300 can be pressed against the side wall of the intake passage 110 by the sealing element. That is, the circumferential side of the sealing element 300 can deform the sealing element by pressing it, thereby abutting against the side wall of the intake passage 110.

[0049] Understandably, when the sealing element 300 closes the air intake passage 110, the sealing element is positioned between the circumferential side of the sealing element 300 and the side wall of the air intake passage 110. This allows the sealing element to seal the gap between the sealing element 300 and the side wall of the air intake passage 110, thereby improving the airtightness of the air intake passage 110. This prevents dust and moisture from the external environment from seeping into the evaporator 200, avoiding clogging of the filter element of the evaporator 200, and thus preventing the air supply volume of the air conditioning system from recirculating. Simultaneously, because the gap between the sealing element 300 and the side wall of the air intake passage 110 is sealed by the sealing element, there will be no air leakage in the air intake passage 110 when the air conditioning system is in recirculation mode.

[0050] The vehicle air conditioning evaporator intake system of this application embodiment, such as Figure 1 and Figure 4 As shown, an air intake plate 120 is provided at the inlet end 111 of the air intake channel 110. The air intake plate 120 can be fixedly installed at the inlet end 111 of the air intake channel 110 by means of bolt connection, snap connection or adhesive connection, so that the air in the external environment needs to pass through the air intake plate 120 to enter the air intake channel 110, so that the air intake plate 120 can filter the air in the external environment and block some water vapor, dust and other impurities from the outside.

[0051] Furthermore, multiple air inlets 121 are provided on the air intake plate 120. The air inlets 121 can connect the air intake channel 110 with the external environment, so that the air from the external environment needs to enter the air intake channel 110 through the air inlet 121. When the sealing member 300 closes the air intake channel 110, the extension line of the axis of the air intake port 121 intersects the side wall of the air intake channel 110 on the side of the sealing member 300 away from the evaporator 200. That is, the air intake port 121 faces the side wall of the air intake channel 110. When the air from the external environment enters the air intake channel 110 through the air intake port 121, the airflow will first flow along the axis of the air intake port 121, and then the airflow will hit the side wall of the air intake channel 110, so that dust, water vapor and other particles in the airflow can adhere to the side wall of the air intake channel 110. That is, the airflow can be separated from dust and water vapor. Then the airflow enters from the side of the sealing member 300 away from the evaporator 200 to the side of the sealing member 300 close to the evaporator 200, and then enters the interior of the evaporator 200.

[0052] It is worth mentioning that regardless of whether the sealing component 300 opens or closes the air intake channel 110, the air from the external environment, when entering the air intake channel 110 through the air intake port 121, will flow along the axial direction of the air intake port 121, and then separate dust, water vapor, and other impurities by impacting the side wall of the air intake channel 110. When the sealing component 300 opens the air intake channel 110, the cooperation between the air intake port 121 and the side wall of the air intake channel 110 can effectively separate dust and water vapor in the airflow, avoiding affecting the operation of the evaporator 200; when the sealing component 300 closes the air intake channel 110, the cooperation between the air intake port 121 and the side wall of the air intake channel 110 can effectively separate dust and water vapor in the airflow, avoiding contamination of the sealing component 300 and reducing the adhesion of dust and water vapor on the sealing component 300.

[0053] Furthermore, in this embodiment, the axis of the air inlet 121 forms an angle of 45 degrees ± 5 degrees with the surface of the air inlet plate 120.

[0054] In some embodiments, such as Figure 4As shown, the intake passage 110 has a first sidewall 113 and a second sidewall 114 along a first direction, wherein the first sidewall 113 and the second sidewall 114 are positioned opposite each other, and the first direction is perpendicular to the flow direction of the airflow in the intake passage 110.

[0055] Furthermore, combined Figure 4 and Figure 11 As shown, the sealing member 300 has a first side 301 and a second side 302 along a first direction, wherein the first side 301 and the second side 302 are positioned opposite each other. The sealing member 300 located in the air intake channel 110 has its first side 301 corresponding to the first side wall 113 of the air intake channel 110 and its second side 302 corresponding to the second side wall 114 of the air intake channel 110. The first side 301 of the sealing member 300 is rotatably connected to the first side wall 113, and the second side 302 of the sealing member 300 is rotatably connected to the second side wall 114.

[0056] The sealing member 300 of this embodiment can rotate within the air intake channel 110 via its first side 301 and second side 302, thereby enabling the sealing member 300 to open or close the air intake channel 110. When the sealing member 300 rotates, causing its circumferential side to fit against the circumferential sidewall of the air intake channel 110, the air intake channel 110 is closed. When the sealing member 300 rotates, creating an opening between its circumferential side and the circumferential side of the air intake channel 110 for airflow, the air intake channel 110 is opened.

[0057] Furthermore, combined Figure 4 and Figure 11 As shown, in this embodiment of the application, a first rotating shaft 301a is provided on the first side 301, a second rotating shaft 302a is provided on the second side 302, a first mounting hole 113a is provided on the first side wall 113, and a second mounting hole 114a is provided on the second side wall 114. The first rotating shaft 301a is rotatably connected in the first mounting hole 113a, and the second rotating shaft 302a is rotatably connected in the second mounting hole 114a. This allows the sealing member 300 to be rotatably connected to the air intake channel 110 via the first side 301 and the second side 302, thereby enabling the sealing member 300 to open or close the air intake channel 110.

[0058] Of course, in some preferred embodiments, the mobility of the blocking member 300 is not necessarily in the form of rotation. For example, the mobility of the blocking member 300 can also be translational. The blocking member 300 can be translated in a first direction under the drive of the motor, thereby realizing the opening or closing of the air intake channel 110. This is not particularly limited.

[0059] In some embodiments, combined with Figure 1 and Figures 3-6 As shown, the intake channel 110 has a third sidewall 115 and a fourth sidewall 116 along the second direction. The third sidewall 115 and the fourth sidewall 116 are positioned opposite each other. The second direction is perpendicular to the airflow direction in the intake channel, and the first direction is perpendicular to the second direction. The third sidewall 115 is connected to the first sidewall 113 and the second sidewall 114, and the fourth sidewall 116 is connected to the first sidewall 113 and the second sidewall 114, respectively. That is, the intake channel 110 is a square channel composed of the first sidewall 113, the second sidewall 114, the third sidewall 115 and the fourth sidewall 116.

[0060] Furthermore, such as Figure 3 and Figure 5 As shown, a first abutment 115a is provided on the third side wall 115, such as Figure 4 and Figure 6 As shown, a second abutment 116a is provided on the fourth sidewall 116. The first abutment 115a is formed by the bending deformation of the third sidewall 115, and the second abutment 116a is formed by the bending deformation of the fourth sidewall 116. The first abutment 115a protrudes from the third sidewall 115, and the second abutment 116a protrudes from the fourth sidewall 116. Figures 3-6 As shown, the above-mentioned sealing element includes a first sub-seal 410 and a second sub-seal 420. The first sub-seal 410 is disposed on the first abutment 115a, and the second sub-seal 420 is disposed on the second abutment 116a. Specifically, the first sub-seal 410 is disposed on the side of the first abutment 115a near the outlet end 112 of the air intake channel 110, and the second sub-seal 420 is disposed on the side of the second abutment 116a near the inlet end 111 of the air intake channel 110.

[0061] like Figure 11As shown, the sealing member 300 of this application embodiment has a third side 303 and a fourth side 304 along the second direction. The third side 303 and the fourth side 304 are positioned opposite each other. The third side 303 is connected to the first side 301 and the second side 302, respectively, and the fourth side 304 is connected to the first side plate and the second side 302, respectively. The sealing member 300 located in the air intake passage 110 has its third side 303 positioned on the side of the first stop 115a near the outlet end 112 of the air intake passage 110, and its fourth side 304 positioned on the side of the second stop 116a near the inlet end 111 of the air intake passage 110. Therefore, it can be understood that when the sealing member 300 rotates counterclockwise, the third side 303 of the sealing member 300 will move towards the direction closer to the first stop 115a, and the fourth side 304 of the sealing member 300 will move towards the direction closer to the second stop. When the third side 303 abuts against the first stop 115a and the fourth side 304 abuts against the second stop 116a, the sealing member 300 closes the air intake passage 110. When the sealing member 300 rotates clockwise, the third side 303 of the sealing member 300 moves away from the first stop 115a, and the fourth side 304 of the sealing member 300 moves away from the second stop 116a, thereby opening the air intake passage 110.

[0062] Furthermore, since a first sub-seal 410 is provided on the first abutment 115a and a second sub-seal 420 is provided on the second abutment 116a, when the sealing member 300 rotates counterclockwise, the third side 303 of the sealing member 300 will press against the first abutment 115a by squeezing the first sub-seal 410. Similarly, the fourth side 304 of the sealing member 300 will press against the second abutment 116a by squeezing the second sub-seal 420. The first abutment 115a can seal the gap between the third side 303 and the first abutment 115a by deforming. The second abutment 116a can also seal the gap between the fourth side 304 and the second abutment 116a by deforming. This can improve the sealing effect of the sealing member 300 when closing the air intake passage 110, better prevent dust and moisture in the external environment from penetrating into the evaporator 200, and also better prevent air leakage in the air intake passage 110 when the air conditioning system is in internal circulation.

[0063] It is worth mentioning that, since the first sub-seal 410 has a certain elasticity, it can better buffer the compression between the third side 303 and the first stop 115a, avoid hard contact between the third side 303 and the first stop 115a, and reduce collision noise. Similarly, since the second sub-seal 420 has a certain elasticity, it can better buffer the compression between the fourth side 304 and the second stop 116a, avoid hard contact between the fourth side 304 and the second stop 116a, and reduce collision noise.

[0064] In some embodiments, such as Figures 3-10 As shown, the aforementioned sealing element also includes a third sub-seal 430 and a fourth sub-seal 440, wherein, as Figure 7 and Figure 8 As shown, a third sub-seal 430 is provided on the third side 303, and a fourth sub-seal 440 is provided on the fourth side 304. When the sealing member 300 rotates counterclockwise, the third side 303 of the sealing member 300 drives the third sub-seal 430 to move towards the first abutment 115a, and the fourth side 304 of the sealing member 300 drives the fourth sub-seal 440 to move towards the second abutment 116a, so that the third side 303 can be pressed against the first sub-seal 410 by the third sub-seal 430. Figure 3 and Figure 5 As shown, the fourth side 304 can be squeezed by the fourth sub-seal 440 and the second sub-seal 420, thereby achieving the closure of the air intake passage 110 by the sealing member 300.

[0065] It is understandable that the mutual compression between the third sub-seal 430 and the first sub-seal 410 can effectively improve the sealing effect between the third side 303 and the first abutment 115a. Similarly, as Figure 4 and Figure 6 As shown, the mutual compression between the fourth sub-seal 440 and the second sub-seal 420 can better improve the sealing effect between the fourth side 304 and the second stop 116a, thereby better improving the sealing effect when the sealing member 300 closes the air intake passage 110, better preventing dust, water vapor and other substances in the external environment from penetrating into the evaporator 200, and also better preventing air leakage in the air intake passage 110 when the air conditioning system is in internal circulation.

[0066] It should be noted that, in some preferred embodiments, the first sub-seal 410 can extend along the circumferential direction of the air intake channel 110 to the first sidewall 113 and / or the second sidewall 114, and the second sub-seal 420 can extend along the circumferential direction of the air intake channel 110 to the first sidewall 113 and / or the second sidewall 114, such that the two ends of the first sub-seal 410 are connected to the two ends of the second sub-seal 420, so that the first sub-seal 410 and the second sub-seal 420 form an annular structure. This allows the cooperation of the first sub-seal 410 and the second sub-seal 420 to form a sealing effect not only on the third sidewall 115 and the fourth sidewall 116, but also on the first sidewall 113 and the second sidewall 114, so that the circumferential side of the sealing member 300 can completely seal with the circumferential sidewall of the air intake channel 110, thereby improving the sealing effect. Of course, the third sub-seal 430 can extend along the circumferential direction of the sealing member 300 to the first side 301 and / or the second side 302, and the fourth sub-seal 440 can extend along the circumferential direction of the sealing member 300 to the first side 301 and / or the second side 302, so that the two ends of the third sub-seal 430 are connected to the two ends of the fourth sub-seal 440, so that the third sub-seal 430 and the fourth sub-seal 440 form an annular structure. Thus, the cooperation of the third sub-seal 430 and the fourth sub-seal 440 can not only form a sealing effect on the third side 303 and the fourth side 304, but also form a sealing effect on the first side 301 and the second side 302, so that the circumferential side of the sealing member 300 can completely seal with the circumferential sidewall of the air intake passage 110, thereby improving the sealing effect.

[0067] In some embodiments, combined with Figures 9-10 As shown, a first mounting groove 431 is provided on the third sub-seal 430. Specifically, the first mounting groove 431 extends along the length direction of the third sub-seal 430. The first mounting groove 431 allows the third side 303 to extend into it, that is, the third sub-seal 430 can be sleeved on the third side 303 through the first mounting groove 431. Figures 7-8 As shown. A first through hole 310 is also provided on the third side 303, as... Figure 11 As shown, the first through hole 310 penetrates the sealing member 300, and along the extending direction of the third side 303, multiple first through holes 310 are spaced apart on the third side 303. Figures 9-10 As shown, a first positioning post 431a is provided in the first mounting groove 431, and multiple first positioning posts 431a are spaced apart in the first mounting groove 431 along the extending direction of the first mounting groove 431. When the third side 303 is in the first mounting groove 431, the multiple first positioning posts 431a are correspondingly located in the multiple first through holes 310, as shown. Figure 7 and Figure 8As shown, the cooperation between the first positioning post 431a and the first through hole 310 can limit the third sub-seal 430, thereby better preventing the third sub-seal 430 from falling off the third side 303 and better improving the structural stability of the third sub-seal 430 installed on the third side 303.

[0068] Furthermore, combined Figures 9-10 As shown, a second mounting groove 441 is provided on the fourth sub-seal 440. Specifically, the second mounting groove 441 extends along the length direction of the fourth sub-seal 440. The second mounting groove 441 allows the fourth side 304 to extend into it, that is, the fourth sub-seal 440 can be sleeved on the fourth side 304 through the second mounting groove 441. Figure 7 and Figure 8 As shown. A second through hole 320 is also provided on the fourth side 304, as... Figure 11 As shown, the second through hole 320 penetrates the sealing member 300, and along the extending direction of the fourth side 304, multiple second through holes 320 are spaced apart on the fourth side 304. Figures 9-10 As shown, a second positioning post 441a is provided in the second mounting groove 441, and multiple second positioning posts 441a are spaced apart in the second mounting groove 441 along the extending direction of the second mounting groove 441. When the fourth side 304 is in the second mounting groove 441, the multiple second positioning posts 441a are correspondingly located in the multiple second through holes 320, as shown. Figure 7 and Figure 8 As shown, the cooperation between the second positioning post 441a and the second through hole 320 can limit the fourth sub-seal 440, thereby better preventing the fourth sub-seal 440 from falling off the fourth side 304 and better improving the structural stability of the fourth sub-seal 440 installed on the fourth side 304.

[0069] In some embodiments, such as Figure 8 and Figure 11 As shown, along the thickness direction of the sealing member 300, the sealing member 300 has a first surface 305 and a second surface 306, wherein the first surface 305 and the second surface 306 are positioned opposite each other. When the sealing member 300 closes the air intake passage 110, the first surface 305 is further away from the evaporator 200 than the second surface 306.

[0070] The sealing member 300 of this application embodiment has at least one connecting strip 330 provided on the first surface 305, such as Figure 5 , Figures 8-10As shown, the connecting strip 330 is embedded in the first surface 305. The connecting strip 330 has a first end and a second end, wherein the first end of the connecting strip 330 is connected to the third sub-seal 430, and the second end of the connecting strip 330 is connected to the fourth sub-seal 440. It is understood that by connecting the third sub-seal 430 and the fourth sub-seal 440 through the connecting strip 330, the third sub-seal 430 and the fourth sub-seal 440 can form a whole. In this embodiment, the connecting strip 330, the third sub-seal 430, and the fourth sub-seal 440 are made of the same material, so that when the third sub-seal 430 is installed on the third side 303, and the fourth sub-seal 440 is installed on the fourth side 304, the third sub-seal 430 and the fourth sub-seal 440 can... The connecting strip 330 can be stretched, so that in the installed state, the connecting strip 330 can exert a pulling force on the third sub-seal 430 and the fourth sub-seal 440, thereby enabling the third sub-seal 430 to be stably fitted on the third side 303, improving the stability of the connection between the third sub-seal 430 and the third side 303. Similarly, it also enables the fourth sub-seal 440 to be stably fitted on the fourth side 304, improving the stability of the connection between the fourth sub-seal 440 and the fourth side 304.

[0071] Furthermore, such as Figure 7 As shown, a groove 340 is also provided on the first surface 305, such as... Figure 9 and Figure 10 As shown, a protrusion 331 is provided on the connecting strip 330, wherein the protrusion 331 is embedded in the groove 340, thereby realizing the embedded connection of the connecting strip 330 on the first surface 305, improving the stability of the relative position of the connecting strip 330 and the first surface 305, preventing the connecting strip 330 from shaking or falling off, and thus improving the stability of the third sub-seal 430 and the fourth sub-seal 440 installed on the sealing member 300.

[0072] Furthermore, in this embodiment of the application, a plurality of connecting strips 330 are provided on the first surface 305, and the plurality of connecting strips 330 are spaced apart on the first surface 305. The cooperation of the plurality of connecting strips 330 can improve the stability of pulling the third sub-seal 430 and the fourth sub-seal 440, and the force is more even, thereby improving the stability of the third sub-seal 430 and the fourth sub-seal 440 installed on the sealing member 300.

[0073] It is understood that, in some preferred embodiments, the connecting strip 330 may also be disposed on the second surface 306, which can also improve the stability of the installation of the third sub-seal 430 and the fourth sub-seal 440 on the sealing member 300.

[0074] In some embodiments, such as Figure 11 As shown, at least one reinforcing rib 350 is provided on the first surface 305. The provision of the reinforcing rib 350 can better improve the structural strength of the sealing member 300, making the sealing member 300 less prone to deformation and bending. Therefore, when the third side 303 of the sealing member 300 is pressed on the first abutment 115a and the fourth side 304 of the sealing member 300 is pressed on the second abutment 116a, the relative position of the third side 303 and the first abutment 115a can remain stable, and the relative position of the fourth side 304 and the second abutment 116a can remain stable, thereby effectively improving the sealing effect between the sealing member 300 and the side wall of the air intake channel 110.

[0075] Of course, at least one reinforcing rib 350 can also be provided on the second surface 306, which can also improve the structural strength of the sealing component 300, making the sealing component 300 less prone to deformation and bending, and effectively improving the sealing effect between the sealing component 300 and the side wall of the air intake channel 110.

[0076] It should be noted that the reinforcing ribs 350 provided on the sealing component 300 can be formed by bending or folding the sealing component 300 itself, such as by rolling on the sealing component 300, or by fixing and installing it by bolt connection, snap connection or other methods, and there is no particular limitation on this.

[0077] In some embodiments, the sealing element described above can be at least one of rubber or sponge, which can seal the gap between the circumferential side of the sealing element 300 and the side wall of the air intake channel 110, and can also buffer the contact between the third side 303 and the first abutment 115a and the fourth side 304 and the second abutment 116a.

[0078] Furthermore, in the embodiments of this application, the first sub-seal 410 and the second sub-seal 420 are both sponge parts; the third sub-seal 430 and the fourth sub-seal 440 are both rubber parts, and since the material of the connecting strip 330 is the same as that of the third sub-seal 430 and the fourth sub-seal 440, the connecting strip 330 is also a rubber part.

[0079] It is worth mentioning that the sponge component, while possessing elasticity, also exhibits excellent adsorption properties for moisture and dust. Therefore, the first sub-seal 410 and the second sub-seal 420 possess both elasticity and excellent adsorption properties for moisture and dust. When the sealing component 300 closes the air intake passage 110, the third side 303 is pressed against the first abutment 115a by the first sub-seal 410 and the third sub-seal 430. While the first sub-seal 410, in conjunction with the third sub-seal 430, seals the gap between the third side 303 and the first abutment 115a, the first sub-seal 410 also adsorbs moisture and dust from the surrounding air, preventing moisture and dust from seeping into the evaporator 200 from between the third side 303 and the first abutment 115a. Similarly... When the sealing member 300 closes the air intake passage 110, the fourth side 304 is pressed against the second abutment 116a by the second sub-seal member 420 and the fourth sub-seal member 440. While the second sub-seal member 420 cooperates with the fourth sub-seal member 440 to seal the gap between the fourth side 304 and the second abutment 116a, the second sub-seal member 420 can also adsorb water vapor and dust in the surrounding air to prevent water vapor and dust from seeping into the evaporator 200 from between the fourth side 304 and the second abutment 116a.

[0080] In some embodiments, such as Figure 4 As shown, when the sealing member 300 closes the air intake passage 110, the extension surface of the inlet end 111 of the air intake passage 110 intersects with the extension surface of the sealing member 300. That is, the inlet end 111 of the air intake passage 110 and the sealing member 300 have a certain angle. This allows the air from the external environment to enter the air intake passage 110 through the air intake plate 120 at the inlet end 111 of the air intake passage 110. The airflow direction has a certain angle with the sealing member 300, causing the airflow to hit the side wall of the air intake passage 110 and change its direction before flowing through the sealing member 300 to the evaporator 200.

[0081] It is understood that, through the positional design of the air intake end of the air intake channel 110 and the sealing member 300 in this embodiment of the application, it is possible to better ensure that the air from the external environment can impact the side wall of the air intake channel 110 after entering the air intake channel 110, thereby separating impurities such as dust and water vapor in the airflow and improving the cleanliness of the airflow entering the evaporator 200.

[0082] In some embodiments, such as Figures 1-4As shown, a rotatable internal circulation damper 500 is also provided at the inlet end 111 of the air intake passage 110. The internal circulation damper 500 is connected to an external drive motor 520, and the internal circulation damper 500 is also connected to a blocking component 300 via a linkage 510. When the external drive motor 520 drives the internal circulation damper 500 to rotate, thereby opening the internal circulation damper 500, the internal circulation damper 500 simultaneously drives the blocking component 300 to rotate via the linkage 510, thereby closing the air intake passage 110. When the external drive motor 520 drives the internal circulation damper 500 to rotate, thereby closing the internal circulation damper 500, the internal circulation damper 500 simultaneously drives the blocking component 300 to rotate via the linkage 510, thereby opening the air intake passage 110.

[0083] It is understandable that by driving the internal circulation damper 500 through the external drive motor 520, the switching between internal circulation and external circulation modes in the air conditioning system can be effectively achieved. Specifically, during internal circulation operation, the internal circulation damper 500 is in the open state, and the sealing component 300 closes the air intake passage 110; during external circulation operation, the internal circulation damper 500 is in the closed state, and the sealing component 300 opens the air intake passage 110.

[0084] Furthermore, the internal circulation damper 500 and the sealing component 300 can be driven by different drive devices. That is, the internal circulation damper 500 and the sealing component 300 can also be in a non-linkage state, as long as the two working modes of internal circulation operation and external circulation operation can be switched between each other. There are no special restrictions on this.

[0085] Secondly, this application also provides a vehicle that includes the above-mentioned vehicle air conditioning evaporator intake system, thus possessing the corresponding technical effects and advantages described above.

[0086] Furthermore, the vehicles in this application embodiment may specifically be tractor-trailers, cargo trucks, lorries, commercial vehicles, new energy vehicles, etc., without any particular limitation.

[0087] In some embodiments, when the vehicle air conditioning evaporator intake system is applied in the vehicle described above, the inlet end 111 of the intake passage 110 faces the rear of the vehicle. For example, when the vehicle is moving forward, the inlet end 111 of the intake passage 110 faces away from the direction of travel of the vehicle, and when the vehicle is moving backward, the inlet end 111 of the intake passage 110 faces the direction of travel of the vehicle.
