Description

Air conditioning module and vehicle Technical Field

[0001] The present disclosure relates to the field of air conditioning, and more particularly to an air conditioning module, which is, for example, an air conditioning module for a vehicle. The present disclosure also relates to a vehicle comprising such an air conditioning module. Background Art

[0002] When the air conditioning module is used to regulate the gas in a partitionable space, more specifically to regulate the temperature and / or flow of the gas, the partitionable space is, for example, a vehicle cabin including a main driver's area, a co-driver's area, a rear area, or areas behind the main driver and behind the co-driver. It is usually expected that each area can be independently regulated by the air conditioning module according to actual needs. Known air conditioning modules usually include a heater, such as an electric heater, for heating the gas flowing through it. When it is necessary to use an air conditioning module to independently regulate the various partitions of the space equipped with the air conditioning module, it is also expected that the electric heater of the air conditioning module is divided into heating parts corresponding to each partition. However, this is difficult to achieve in terms of design, process and integration into the air conditioning module. In this case, a compromise is to divide the electric heater into fewer heating parts than the number of partitions of the space, so that one heating part can be used for two or more space partitions that are independently regulated, thereby meeting the design, process and integration constraints. However, this brings a new problem, that is, the same heating part of the electric heater may be used for two or more independently regulated space partitions. When the first partition of the two or more space partitions does not need to use heated air and the second partition needs to use heated air, the first air flow channel corresponding to the first partition will be closed. At this time, no air flow will be able to flow through the part of the heating part of the electric heater corresponding to the first air flow channel, causing dry burning in this part. Dry burning can easily damage the electric heater or air-conditioning module and pose a safety hazard.

[0003] There is a need for a new air conditioning module that solves the problems of the prior art while providing other advantages.

[0129] With reference to Figures 1-3, 5-7, 13-14, and 19, the present invention provides an air conditioning module 10, for example, an air conditioning module 10 for a vehicle, for conditioning air entering a vehicle cabin, such as a motor vehicle, an electric vehicle, or a hybrid vehicle. According to one embodiment, the air conditioning module 10 may include a housing 100 and a heater disposed within the housing 100. The housing 100 is configured to allow airflow therethrough. In a specific embodiment, the housing 100 may include one or more air inlets and multiple outlets. The inlets are configured to allow airflow into the housing 100 for conditioning, such as heating or cooling, by the air conditioning module 10, and the outlets are configured to discharge the conditioned airflow from the housing 100, for example, into corresponding areas within the vehicle cabin. The heater is configured to heat the airflow passing therethrough during operation and may include an electric heater 200. More specifically, the electric heater 200 may include a positive temperature coefficient (PTC) heating element. Optionally, the heater may also include other heaters, such as a heating core 290 that heats the airflow using a heat transfer fluid. In one embodiment, as shown in FIG2 , the air conditioning module 10 is a three-zone air conditioning module, which may include three independently regulated and controlled zones: a first zone Z1a, a second zone Z2a, and a third zone Z3a. In another embodiment, as shown in FIG3 , the air conditioning module 10 is a four-zone air conditioning module, which may include four independently regulated and controlled zones: a first zone Z1b, a second zone Z2b, a third zone Z3b, and a fourth zone Z4b.

[0130] As shown in Figures 4-12 and 15-18, according to some embodiments, the electric heater 200 may include a first heating portion 210 that allows airflow to pass through. In a specific embodiment, the first heating portion 210 is operated independently of the rest of the electric heater 200, for example, it is independently turned on and off. It should be noted that in the sense of this article, when the electric heater 200 or one of its parts is turned on, current will flow through the electric heater 200 or one of its parts; when the electric heater 200 or one of its parts is turned off, no current will flow through the electric heater 200 or one of its parts. As shown in the figure, the housing 100 may be provided with a partition wall, referred to herein as a first partition wall 110, which is provided to extend from the first heating portion toward the downstream direction of the airflow flow to separate the first airflow channel 2001 and the second airflow channel 2002 downstream of the first heating portion 210. That is, the housing 100 of the air conditioning module 10 is provided with a first airflow channel 2001 and a second airflow channel 2002 in the space downstream of the first heating portion 210 of the electric heater 200. The first airflow channel 2001 and the second airflow channel 2002 are separated from each other by the first partition wall 110. In a specific embodiment, the first airflow channel 2001 and the second airflow channel 2002 are each defined by the first partition wall 110 and other corresponding portions of the housing 100. In a specific embodiment, the first airflow channel 2001 and the second airflow channel 2002 can lead to different outlets of the housing 100. In an exemplary embodiment, the first airflow channel 2001 can lead to the right front blowing face outlet 1005 and / or the right front blowing foot outlet 1006 (shown in FIG1 ) among the outlets of the housing 100. The right front blowing face outlet 1005 and / or the right front blowing foot outlet 1006 can lead to the right front area of ​​the vehicle compartment, i.e., the passenger compartment. The second airflow channel 2002 can lead to the rear outlet of the housing 100, more specifically, the right rear blowing face foot outlet 1009 (shown in FIG1 and FIG5-7 ) among the rear outlets. The right rear blowing face foot outlet 1009 can, for example, lead to the right rear area of ​​the vehicle compartment, i.e., the rear area behind the passenger compartment. It should be noted that the corresponding arrangement of the first airflow channel 2001 and the second airflow channel 2002 and the corresponding outlets of the housing 100 is merely illustrative and not restrictive.

[0131] In some embodiments, as shown in Figures 6-12, 15-18, and 20, a bypass hole, referred to herein as a first bypass hole 111, can be provided in the first partition wall 110. Accordingly, the air conditioning module 10 further includes a first bypass valve 300a disposed in the housing 100 and cooperating with the first bypass hole 111. The first bypass hole 111 can be, for example, a portion of a sector, or can be circular, rectangular, or have any other suitable shape. The first bypass valve 300a can be switched between at least a first position (schematically shown in Figures 6, 11, 15-18, and 22) that closes the first bypass hole 111 and a second position (schematically shown in Figures 7-10 and 12) that at least partially opens the first bypass hole 111. More specifically, when one of the first airflow channel 2001 and the second airflow channel 2002 is closed, i.e., no longer able to lead to the corresponding outlet of the housing 100, the first bypass valve 300a is configured to be in the second position to at least partially open the first bypass hole 111, so that the first airflow channel 2001 and the second airflow channel 2002 are connected through the first bypass hole 111. Thus, the unheated airflow can still pass through the entire first heating section 210 and enter the first airflow channel 2001 and the second airflow channel 2002 located downstream of the first heating section 210. Since the first bypass hole 111 is at least partially open, the heated airflow downstream of the first heating section 210 can flow through the first bypass hole 111 into the airflow channel in the first airflow channel 2001 or the second airflow channel 2002 that is not closed, i.e., is open to lead to the corresponding outlet of the housing 100, and from there flow to the corresponding outlet of the housing 100. This effectively prevents any portion of the first heating section 210 from drying out under any conditions.

[0132] In some embodiments, as schematically shown in Figures 8-12 and 15-18, the air conditioning module 10 may further include a first channel valve 1001 disposed on the housing 100 for the first air flow channel 2001. The first channel valve 1001 may open or close the first air flow channel 2001. When the first air flow channel 2001 is opened, the first air flow channel 2001 can lead to the corresponding outlet of the housing 100. When the first air flow channel 2001 is closed, the first air flow channel 2001 no longer leads to the corresponding outlet of the housing 100. Optionally, the air conditioning module 10 may further include a second channel valve 1002 disposed on the housing 100 for the second air flow channel 2002. The second channel valve 1002 may open or close the second air flow channel 2002. When the second air flow channel 2002 is opened, the second air flow channel 2002 can lead to the corresponding outlet of the housing 100. When the second air flow channel 2002 is closed, the second air flow channel 2002 no longer leads to the corresponding outlet of the housing 100.

[0133] As shown in Figures 7-9, in the exemplary embodiment shown therein, the first air flow channel 2001 is closed, more specifically, it is closed via the first channel valve 1001 so as to no longer be able to lead to the corresponding outlet of the housing 100, while the second air flow channel 2002 is opened, more specifically, it is opened via the second channel valve 1002 so as to be able to lead to the corresponding outlet of the housing 100. The first heating part 210 of the electric heater 200 needs to be in an open state, that is, an energized state. At this time, the first bypass valve 300a needs to be placed in the second position to at least partially open the first bypass hole 111, and the air from the upstream needs to be opened. The heated air flows through the entire first heating portion 210 and reaches the first airflow channel 2001 and the second airflow channel 2002. However, since the first airflow channel 2001 is closed and cannot be connected to the corresponding outlet of the housing 100, the heated air in the first airflow channel 2001 cannot be discharged through the corresponding outlet of the housing 100. Instead, it flows through the at least partially opened first bypass hole 111 into the second airflow channel 2002, and is discharged into a predetermined area inside the vehicle cabin, such as the right rear area, through the corresponding outlet of the housing 100 connected to the second airflow channel 2002. This design effectively prevents dry heating of the portion of the first heating portion 210 of the electric heater 200 corresponding to the first airflow channel 2001, thereby ensuring safety. Similarly, as schematically shown in FIG10 , the second air flow channel 2002 is closed, more specifically, closed via the second channel valve 1002 so as to no longer be able to lead to the corresponding outlet of the housing 100, while the first air flow channel 2001 is opened, more specifically, opened via the first channel valve 1001 so as to be able to lead to the corresponding outlet of the housing 100. The first heating portion 210 needs to be in an open state, i.e., an energized state. At this time, the first bypass valve 300a also needs to be placed in the second position to at least partially open the first bypass hole 111. The air flow from the upstream needs to pass through the entire first bypass hole 111. The heated air flows through the first heating portion 210 and into the first airflow channel 2001 and the second airflow channel 2002. However, since the second airflow channel 2002 is closed and thus cannot be discharged through the corresponding outlet of the housing 100, the heated airflow in the second airflow channel 2002 cannot be discharged through the corresponding outlet of the housing 100. Instead, the heated airflow flows through the at least partially opened first bypass hole 111 into the first airflow channel 2001, and is discharged into a predetermined area of ​​the vehicle interior, such as the right front area, through the corresponding outlet of the housing 100 connected to the first airflow channel 2001. This effectively prevents dry heating of the portion of the first heating portion 210 of the electric heater 200 corresponding to the second airflow channel 2002.Furthermore, as schematically shown in FIG11 , when both the first airflow channel 2001 and the second airflow channel 2002 are open, the first heating unit 210 is turned on, i.e., powered on. It is necessary to allow airflow from upstream to pass through the entire first heating unit 210. In this case, the first bypass valve 300a can be placed in the first position, closing the first bypass hole 111, to allow independent regulation and control of the corresponding air conditioning module portions of the first airflow channel 2001 and the second airflow channel 2002, and thus the corresponding areas of the vehicle cabin. Furthermore, as schematically shown in FIG12 , when both the first airflow channel 2001 and the second airflow channel 2002 are closed, the first heating unit 210 is turned off, i.e., powered off. It is no longer necessary to allow airflow from upstream to pass through the first heating unit 210. In this case, the first bypass valve 300a can be placed in either the first position or the second position.

[0134] In some embodiments, as shown in FIG. 4-19 , the electric heater 200 may further include a second heating portion 220 that allows airflow. In a specific embodiment, the second heating portion 220 is operated independently of the rest of the electric heater 200, more specifically, independently of the first heating portion 210, for example, independently opened and closed. The housing 100 may be provided with a partition wall, referred to herein as a second partition wall 120, extending from the second heating portion 220 toward the downstream direction of airflow to separate the third airflow channel 2003 from the fourth airflow channel 2004 downstream of the second heating portion 220. Specifically, the housing 100 of the air conditioning module 10 is provided with the third airflow channel 2003 and the fourth airflow channel 2004 in the space downstream of the second heating portion 220 of the electric heater 200, and the third airflow channel 2003 and the fourth airflow channel 2004 are separated from each other by the second partition wall 220. In a specific embodiment, the third airflow channel 2003 and the fourth airflow channel 2004 are each defined by the second partition wall 120 and other corresponding portions of the housing 100. In a specific embodiment, the third airflow channel 2003 and the fourth airflow channel 2004 can lead to different outlets of the housing 100. In an exemplary embodiment, the third airflow channel 2003 can lead to a rear outlet among the outlets of the housing 100, more specifically, a left rear face-blowing and foot-blowing outlet 1010 among the rear outlets (shown in Figures 1 and 5-7). The left rear face-blowing and foot-blowing outlet 1010 can, for example, lead to the left rear area of ​​the vehicle cabin, i.e., the rear area behind the driver's seat. The fourth airflow channel 2004 can lead to a left front face-blowing outlet 1007 and / or a left front foot-blowing outlet 1008 (shown in Figure 1) among the outlets of the housing 100. The left front face-blowing outlet 1007 and / or the left front foot-blowing outlet 1008 can lead to the left front area of ​​the vehicle cabin, i.e., the driver's seat. It should be noted that the corresponding arrangement of the third air flow channel 2003 and the fourth air flow channel 2004 and the corresponding outlets of the housing 100 is merely illustrative and not restrictive.

[0135] In some embodiments, as shown in Figures 5, 8-12, 14-19, 23, and 26, a bypass hole, referred to herein as the second bypass hole 121, can be provided in the second partition wall 120. Accordingly, the air conditioning module 10 further includes a second bypass valve 300b disposed in the housing 100 and cooperating with the second bypass hole 121. The second bypass hole 121 can be, for example, a portion of a sector, or can be circular, rectangular, or have any other suitable shape. The second bypass valve 300b can be switched between at least a first position (schematically shown in Figures 5-13, 17-18, and 25) that closes the second bypass hole 121 and a second position (schematically shown in Figures 14-16 and 26) that at least partially opens the second bypass hole 121. More specifically, when one of the third airflow channel 2003 and the fourth airflow channel 2004 is closed, i.e., no longer able to lead to the corresponding outlet of the housing 100, the second bypass valve 300b is configured to be in the second position to at least partially open the second bypass hole 121, so that the third airflow channel 2003 and the fourth airflow channel 2004 are connected through the second bypass hole 121. Thus, the unheated airflow can still pass through the entire second heating section 220 and enter the third airflow channel 2003 and the fourth airflow channel 2004 located downstream of the second heating section 220. Since the second bypass hole 121 is at least partially open, the heated airflow downstream of the second heating section 220 can flow through the second bypass hole 121 into the airflow channel in the third airflow channel 2003 or the fourth airflow channel 2004 that is not closed, i.e., is open to lead to the corresponding outlet of the housing 100, and from there flow to the corresponding outlet of the housing 100. This effectively prevents dry heating of any portion of the second heating section 220 under any conditions.

[0136] In some embodiments, as shown in Figures 8-12 and 15-18, the air conditioning module 10 may further include a third channel valve 1003 disposed on the housing 100 for the third air flow channel 2003. The third channel valve 1003 may open or close the third air flow channel 2003. When the third air flow channel 2003 is opened, the third air flow channel 2003 can lead to the corresponding outlet of the housing 100. When the third air flow channel 2003 is closed, the third air flow channel 2003 no longer leads to the corresponding outlet of the housing 100. Optionally, the air conditioning module 10 may further include a fourth channel valve 1004 disposed on the housing 100 for the fourth air flow channel 2004. The fourth channel valve 1004 may open or close the fourth air flow channel 2004. When the fourth air flow channel 2004 is opened, the fourth air flow channel 2004 can lead to the corresponding outlet of the housing 100. When the fourth air flow channel 2004 is closed, the fourth air flow channel 2004 no longer leads to the corresponding outlet of the housing 100.

[0137] As shown in FIG15 , in the exemplary embodiment shown therein, the third air flow channel 2003 is closed, more specifically, it is closed via the third channel valve 1003 so as to no longer be able to lead to the corresponding outlet of the housing 100, while the fourth air flow channel 2004 is opened, more specifically, it is opened via the fourth channel valve 1004 so as to be able to lead to the corresponding outlet of the housing 100. The second heating portion 220 needs to be in an open state, i.e., an energized state. At this time, the second bypass valve 300b needs to be placed in the second position to at least partially open the second bypass hole 121, and the air flow from the upstream needs to pass through the entire The heated air flows through the second heating portion 220 of the electric heater 200 and into the third airflow channel 2003 and the fourth airflow channel 2004. However, since the third airflow channel 2003 is closed and thus cannot be directed to the corresponding outlet of the housing 100, the heated air in the third airflow channel 2003 cannot be discharged through the corresponding outlet of the housing 100. Instead, the heated air flows through the at least partially opened second bypass hole 121 into the fourth airflow channel 2004, and is discharged into a predetermined area of ​​the vehicle interior, such as the left front area, through the corresponding outlet of the housing 100 connected to the fourth airflow channel 2004. This design effectively prevents dry heating of the portion of the second heating portion 220 of the electric heater 200 corresponding to the third airflow channel 2003, thereby ensuring safety. 16, the fourth air flow channel 2004 is closed, more specifically, the fourth channel valve 1004 is closed so as to no longer be able to lead to the corresponding outlet of the housing 100, while the third air flow channel 2003 is opened, more specifically, the third channel valve 1003 is opened so as to be able to lead to the corresponding outlet of the housing 100, and the second bypass valve 300b is also in the second position to at least partially open the second bypass hole 121. The second heating part 220 needs to be in the open state, that is, the energized state. At this time, the second bypass valve 300b needs to be placed in the second position to at least partially open the second bypass hole 121. To open the second heating section 220, the airflow from upstream must pass through the entire second heating section 220 and reach the third airflow channel 2003 and the fourth airflow channel 2004. However, since the fourth airflow channel 2004 is closed and thus cannot be connected to the corresponding outlet of the housing 100, the heated airflow in the fourth airflow channel 2004 cannot be discharged through the corresponding outlet of the housing 100. Instead, it flows through the at least partially opened second bypass hole 121 into the third airflow channel 2003, and is discharged into a predetermined area of ​​the vehicle interior, such as the right rear area, through the corresponding outlet of the housing 100 connected to the third airflow channel 2003. This effectively prevents dry heating of the portion of the second heating section 220 of the electric heater 200 corresponding to the fourth airflow channel 2004.Furthermore, as schematically shown in FIG17 , when both the third airflow channel 2003 and the fourth airflow channel 2004 are open, the second heating unit 220 is turned on, i.e., powered on. It is necessary to allow airflow from upstream to pass through the entire second heating unit 220. In this case, the second bypass valve 300b can be placed in the first position, closing the second bypass hole 121, to allow independent regulation and control of the air conditioning module portions corresponding to the third airflow channel 2003 and the fourth airflow channel 2004, and thus the corresponding areas of the vehicle cabin. Furthermore, as schematically shown in FIG18 , when both the third airflow channel 2003 and the fourth airflow channel 2004 are closed, the second heating unit 220 is turned off, i.e., powered off. It is no longer necessary to allow airflow from upstream to pass through the second heating unit 220. In this case, the second bypass valve 300b can be placed in either the first or second position.

[0138] In some embodiments, as schematically shown in Figures 8-12 and 15-18, the housing 100 of the air conditioning module 10 may also be provided with a main partition wall 130. This main partition wall 130 includes a first partition portion 131 that separates the first heater 210 and the second heater 220 of the electric heater 200 from each other, thereby allowing the first heater 210 and the second heater 220 to operate independently of each other. Furthermore, the main partition wall 130 includes a second partition portion 132 that separates the second airflow channel 2002 and the third airflow channel 2003 from each other. In one embodiment, the first partition portion 131 and the second partition portion 132 are separate pieces; alternatively, the first partition portion 131 and the second partition portion 132 are a single piece.

[0139] In one embodiment, as shown in particular with reference to Figure 4, the electric heater 200 is composed of a first heating part 210 and a second heating part 220 that operate independently of each other, and the first partition portion 131 of the main partition wall 130 separates the first heating part 210 and the second heating part 220 from each other. According to a specific embodiment, the first heating part 210 and the second heating part 220 are each a half of the electric heater 200. Alternatively, the size and even shape of the first heating part 210 and the second heating part 220 can be different. The first partition wall 110 is set as its virtual extension to divide the first heating part 210 into two parts, so that the part of the first heating part 210 corresponding to the first air flow channel 2001 and the part of the first heating part 210 corresponding to the second air flow channel 2002 are the same or different in size. According to a specific embodiment, the second partition wall 120 is configured as a virtual extension thereof, and the second heating portion 220 can be divided into two parts, so that the portion of the second heating portion 220 corresponding to the third airflow channel 2003 and the portion of the second heating portion 220 corresponding to the fourth airflow channel 2004 are of the same or different sizes. Thus, the electric heater 200 only needs to be physically divided into two independently operable parts via the first partition 131, which simplifies the design and manufacturing process and facilitates its integration into the air conditioning module 10.

[0140] In some embodiments, as schematically shown in Figures 8-19, the air conditioning module 10 may further include multiple mixing dampers located upstream of the electric heater 200 in the direction of airflow within the housing 100. For example, the respective mixing dampers may control the types and amounts of airflow directed to corresponding portions of the electric heater 200. More specifically, the air conditioning module 10 may further include an evaporator 500 located upstream of the electric heater 200 in the direction of airflow within the housing 100. In this case, the respective mixing dampers may be configured to control the presence or absence, and amount, of airflow directed to corresponding portions of the electric heater 200 that is cooled by the evaporator 500, and the presence or absence, and amount, of airflow that is not cooled by the evaporator 200.

[0141] In some embodiments, as shown in Figures 8-12 and 15-18, the mixing damper includes: a mixing damper corresponding to the first heating portion 210 of the electric heater 200, which is referred to as a "first type of mixing damper" for distinction; and a mixing damper corresponding to the second heating portion 220 of the electric heater 200, which is referred to as a "second type of mixing damper" for distinction.

[0142] In a first embodiment, as schematically shown in FIG8 , the space in the housing 100 upstream of the electric heater 200 can be divided into a first generally upstream airflow channel 2110 and a second generally upstream airflow channel 2120, separated from each other, for example, by an upstream main partition wall 140a of the housing 100. The upstream main partition wall 140a extends upstream from the electric heater 200 relative to the airflow direction. The first-type mixing damper 1110 is configured to open or close the first generally upstream airflow channel 2110, while the second-type mixing damper 1120 is configured to open or close the second generally upstream airflow channel 2120. When the first heating unit 210 is in operation (i.e., powered on), the first-type mixing damper 1110 should be in a position that at least partially opens the first generally upstream airflow channel 2110 to ensure airflow to the entire first heating unit 210 and prevent dry-burning of any portion of the first heating unit 210. When the first heating unit 210 is not in operation (i.e., powered off), the first-type mixing damper 1110 can be in a position that closes the first generally upstream airflow channel 2110. Similarly, when the second heating portion 220 is in operation (i.e., powered on), the second type mixing damper 1120 should be in a position that at least partially opens the second overall upstream airflow channel 2120 to ensure airflow to the entire second heating portion 220 and prevent dry-burning of any portion of the second heating portion 220. When the second heating portion 220 is inoperative (i.e., powered off), the second type mixing damper 1120 can be in a position that closes the second overall upstream airflow channel 2120. More specifically, the evaporator 500 can be disposed in the housing 100 upstream of the first type mixing damper 110 and the second type mixing damper 1120. It should be noted that in further embodiments, the first overall upstream airflow channel 2110 and the second overall upstream airflow channel 2120 can each include multiple sub-upstream airflow channels, each of which can be provided with a corresponding mixing damper.

[0143] In a second embodiment, as schematically shown in Figures 9-12 and 15-18, the space in the shell 100 located upstream of the electric heater 200 can be divided into a first upstream airflow channel 2101, a second upstream airflow channel 2102, a third upstream airflow channel 2103 and a fourth upstream airflow channel 2104 that are separated from each other, wherein the first upstream airflow channel 2101 and the second upstream airflow channel 2102 correspond to the first heating part 210 of the electric heater 200, and the third upstream airflow channel 2103 and the fourth upstream airflow channel 2104 correspond to the second heating part 220 of the electric heater 200. More specifically, the first upstream airflow channel 2101 and the first airflow channel 2001 correspond to the same portion of the first heating portion 210, the second upstream airflow channel 2102 and the second airflow channel 2002 correspond to the same portion of the first heating portion 210, the third upstream airflow channel 2103 and the third airflow channel 2003 correspond to the same portion of the second heating portion 220, and the fourth upstream airflow channel 2104 and the fourth airflow channel 2004 correspond to the same portion of the second heating portion 220. In a specific embodiment, the housing 100 may include a first upstream partition wall 150, a second upstream partition wall 160, and an upstream main partition wall 140b. Among them, the first upstream partition wall 150 is configured to extend from the first heating part 210 in the upstream direction relative to the airflow flow direction to separate the first upstream airflow channel 2101 and the second upstream airflow channel 2102 from each other, the second upstream partition wall 160 is configured to extend from the first heating part 210 in the upstream direction relative to the airflow flow direction to separate the third upstream airflow channel 2103 and the fourth upstream airflow channel 2104 from each other, and the upstream main partition wall 140b is configured to extend from the electric heater 200 in the upstream direction relative to the airflow flow direction to separate the second upstream airflow channel 2102 and the third upstream airflow channel 2103 from each other. In this case, the first type of mixing damper may include a first mixing damper 1101 configured to open or close the first upstream air flow channel 2101 and a second mixing damper 1102 configured to open or close the second upstream air flow channel 2102; the second type of mixing damper may include a third mixing damper 1103 configured to open or close the third upstream air flow channel 2103 (Figures 13-14 and 19) and a fourth mixing damper 1104 configured to open or close the fourth upstream air flow channel 2104.In this embodiment, as shown in Figures 9-11 and 15-18, when the first heating part 210 is in operation, that is, powered on, the first mixing damper 1101 and the second mixing damper 1102 should be in a position to at least partially open the first upstream airflow channel 2101 and the second upstream airflow channel 2102, respectively, to ensure that airflow can flow to the entire first heating part 210, so as to prevent dry burning of any part of the first heating part 210; as shown in Figure 12, when the first heating part 210 is not in operation, that is, powered off, the first mixing damper 1101 and the second mixing damper 1102 should be in a position to close the first upstream airflow channel 2101 and the second upstream airflow channel 2102, respectively. Similarly, as shown in Figures 9-12 and 15-17, when the second heating unit 220 is in operation, i.e., powered on, the third mixing damper 1103 and the fourth mixing damper 1104 should be in a position to at least partially open the third downstream airflow channel 2103 and the fourth upstream airflow channel 2104, respectively, to ensure that air can flow to the entire second heating unit 220 and prevent any part of the second heating unit 220 from drying out. As shown in Figure 18, when the second heating unit 220 is not in operation, i.e., powered off, the third mixing damper 1103 and the fourth mixing damper 1104 can be in a position to close the third downstream airflow channel 2103 and the fourth upstream airflow channel 2104, respectively. More specifically, the evaporator 500 can be disposed in the housing 100 upstream of the first mixing damper 1101, the second mixing damper 1102, the third mixing damper 1103, and the fourth mixing damper 1104.

[0144] In some embodiments, as shown in Figures 5-6 and 20-22, the first bypass valve 300a is configured as a rotatable flap valve on the housing 100, referred to as the first flap valve. More specifically, the first flap valve can be disposed on a first support shaft 170 supported by the housing 100 and rotate along with the first support shaft 170, for example, by a motor driving the first support shaft 170. This allows the first bypass valve 300a to be easily switched between a first position and a second position. In some embodiments, the first partition wall 110 can be provided with a first arcuate tab 112 that protrudes relative to the first partition wall 110 and surrounds at least a portion of the first bypass hole 111, more specifically, toward the first bypass valve 300a. The first radially outer edge 320a of the first flap valve is configured to complement the first arcuate tab 112, such that, at least in the closed position (i.e., the first position) in which the first flap valve closes the first bypass hole 111, the first radially outer edge 320a of the first flap valve abuts the first arcuate tab 112. It should be noted that the "radially outer edge" here refers to the edge of the first flap valve that is radially outward relative to its rotational center. This ensures a good seal between the first airflow channel 2001 and the second airflow channel 2002 when the first flap valve is in the position closing the first bypass hole 111, while also ensuring smooth rotational switching of the first flap valve between the first and second positions. In a more specific embodiment, a first sealing member 321a, such as a rubber pad, can be provided at the first radially outer edge 320a of the first flap valve. This further ensures a good seal between the first airflow channel 2001 and the second airflow channel 2003.

[0145] Similarly, in some embodiments, as shown in Figures 5-7, 13-14, and 23-26, the second bypass valve 300b can also be configured as a flap valve that can rotate on the housing 100, referred to as a second flap valve. More specifically, the second flap valve can be disposed on a second support shaft 180 supported by the housing 100 and rotate along with the second support shaft 180, for example, by a motor driving the second support shaft 180. This allows the second bypass valve 300b to be easily switched between a first position and a second position. In some embodiments, the second partition wall 120 can be provided with a second curved tab 122 that protrudes relative to the second partition wall 120 and surrounds at least a portion of the second bypass hole 121, more specifically, toward the second bypass valve 300b. The second radially outer edge 320b of the second flap valve is configured to have a complementary shape to the second curved tab 122, such that at least in the closed position (i.e., the first position) in which the second flap valve closes the second bypass hole 121, the second radially outer edge 320b of the second flap valve abuts the second curved tab 122. This ensures that when the second flap valve is in the position closing the second bypass hole 121, the third airflow channel 2003 and the fourth airflow channel 2004 are well sealed relative to each other, while also ensuring smooth rotational switching of the second flap valve between the first and second positions. In a more specific embodiment, a second sealing member 321b, such as a rubber pad, can be provided at the second radial outer edge 320b of the second flap valve. This further ensures the sealing between the third airflow channel 2003 and the fourth airflow channel 2004.

[0146] In some embodiments, as shown in Figures 5-6 and 20-22, the first bypass valve 300a is configured as part of the first defrost priority valve 400a. This allows for a reduction in the number of components of the air conditioning module 10, simplifies component manufacturing and assembly, improves cost-effectiveness, and facilitates a compact structure of the air conditioning module 10. In a specific embodiment, the first defrost priority valve 400a is rotatably disposed, for example, disposed on the first support shaft 170 and capable of rotating therewith. More specifically, the first defrost priority valve 400a can rotate together with the first bypass valve 300a between a first position that closes the first bypass hole 111 and a second position that opens the first bypass hole 111. Furthermore, the first defrost priority valve 400a can also rotate from the second position in a direction away from the first position to a third position, i.e., the defrost priority position, and can be moved from the third position to the second position. In the defrost priority position, the first defrost priority valve 400a closes the rear exhaust outlet of the housing 100 of the air conditioning module 10, which leads to the rear passenger compartment of the vehicle. More specifically, it closes the right rear-facing foot outlet 1009 of the rear exhaust outlet. More specifically, in the defrost priority position, the first bypass valve 300a fully opens the first bypass hole 111. This ensures that the maximum amount of air can flow between the second airflow channel 2002 and the first airflow channel 2001 via the first bypass hole 111, for example, allowing the maximum amount of air to reach the defrost outlet 1011 (shown in FIG. 1 ) of the housing 100 of the air conditioning module 10. More specifically, the first bypass valve 300a is configured to partially open the first bypass hole 111 in the second position, for example, opening the first bypass hole 111 to 50%.

[0147] In some embodiments, as shown in Figures 5-6 and 20-22, the first defrost priority valve 400a is a cylindrical valve referred to herein as the first cylindrical valve 400a. In some embodiments, the first bypass valve 300a is an axial end surface of the first cylindrical valve 400a disposed perpendicular to the rotation axis of the first cylindrical valve 400a. In a specific embodiment, as shown in Figures 21 and 22, the first cylindrical valve includes a first rotational shaft 401a, which is, for example, sleeved on a first support shaft 170 supported by the housing 100 so as to rotate therewith. The first cylindrical valve 400a also includes two first door frame portions 410a and 420a that protrude radially outward from the first rotational shaft 401a and are circumferentially spaced apart. Each first door frame portion includes a first axial end beam 411a, 421a, a second axial end beam 412a, 422a, and a top beam 413a, 423a connected between the first axial end beam 411a, 421a and the second axial end beam 412a, 422a. The first bypass valve 300a is configured to connect the first axial end beams 411a, 421a of the two first door frames 410a, 420a to form an axial end surface of the first cylindrical valve 400a. The first cylindrical valve 400a also includes a first extension portion 430a extending between the top beams 413a, 423a of the two first door frames 410a, 420a and between the second axial end beams 412a, 422a of the two first door frames 410a, 420a. In a more specific embodiment, in the defrost priority position, the axial end face of the first cylindrical valve 400a formed by the first bypass valve 300a abuts against the first partition wall 110, and the second axial end beams 412a, 422a of the two first door frame portions 410a, 420a of the first cylindrical valve 400a abut against the main partition wall 130 mentioned above, more specifically, one side of the second partition portion 132 of the main partition wall 130, and the corresponding rear exhaust outlet of the shell 100, for example, the right rear blowing foot outlet 1009, is closed by means of the first extension portion 130a.

[0148] In some embodiments, as shown in Figures 5-7, 13-14, and 23-26, the second bypass valve 300b is configured as part of the second defrost priority valve 400b. This also reduces the number of components in the air conditioning module 10, simplifies component manufacturing and assembly, improves cost-effectiveness, and further contributes to the compact construction of the air conditioning module 10. In a specific embodiment, the second defrost priority valve 400b is rotatably disposed, for example, on the second support shaft 180 and capable of rotating therewith. More specifically, the second defrost priority valve 400b can rotate together with the second bypass valve 300b between a first position closing the second bypass hole 121 and a second position opening the second bypass hole 121. Furthermore, the second defrost priority valve 400b can also rotate from the second position away from the first position to a third position, i.e., the defrost priority position, and can be transferred from the third position to the second position. In the defrost priority position, the second defrost priority valve 400b closes the rear outlet of the housing 100 of the air conditioning module 10, which leads to the rear area of ​​the vehicle's cabin. More specifically, the left rear face-to-foot outlet 1010 of the rear outlet is closed. More specifically, in the defrost priority position, the second bypass valve 300b fully opens the second bypass hole 121. This ensures that the maximum amount of air can flow between the third airflow channel 2003 and the fourth airflow channel 2004 via the second bypass hole 121, for example, allowing the maximum amount of air to reach the defrost outlet 1011 (shown in FIG. 1 ) of the housing 100 of the air conditioning module 10. More specifically, the second bypass valve 300b is configured to partially open the second bypass hole 121 in the second position, for example, to a 50% opening.

[0149] In some embodiments, as shown in Figures 5-7, 13-14, and 23-26, the second defrost priority valve 400b is a cylindrical valve, referred to herein as a second cylindrical valve 400b. In some embodiments, the second bypass valve 300b is an axial end surface of the second cylindrical valve 400b disposed perpendicular to the rotation axis of the second cylindrical valve 400b.
