As one of the important internal functions, car air conditioning has a direct impact on the driver's experience of using the vehicle.

[0003] However, in the related art, the air-conditioning device used in the vehicle requires separate design of cooling pipes and heating pipes to achieve the regulation of the temperature inside the vehicle. The heat causes the overall space occupied to be large. Therefore, how to improve the space utilization of the air-conditioning device is a technical problem that needs to be solved today. Summary of the invention

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, an embodiment of the present application provides a heat exchanger for an air-conditioning device, comprising a shell, wherein a first heat exchange chamber and a second heat exchange chamber are provided inside the shell, and the first heat exchange chamber and the second heat exchange chamber are independent of each other, wherein the shell has a first opening and a second opening, both of which are connected to the first heat exchange chamber, and the shell also has a third opening and a fourth opening, both of which are connected to the second heat exchange chamber; the first opening and the second opening respectively connect the first heat exchange chamber with the air-conditioning device, and the third opening and the fourth opening respectively connect the second heat exchange chamber with the air-conditioning device, and the air-conditioning device is suitable for inputting refrigerant of the same temperature into the first heat exchange chamber and the second heat exchange chamber so that the first heat exchange chamber and the second heat exchange chamber have the same working mode, and the air-conditioning device is also suitable for inputting refrigerant of different temperatures into the first heat exchange chamber and the second heat exchange chamber or inputting refrigerant into one of the first heat exchange chamber and the second heat exchange chamber so that the first heat exchange chamber and the second heat exchange chamber have different working modes.

[0007] A heat exchanger for an air-conditioning device provided in an embodiment of the present application has a first heat exchange chamber and a second heat exchange chamber that are independent of each other inside a shell, and the first heat exchange chamber and the second heat exchange chamber can be in different working modes according to different refrigerant temperatures or different simultaneous refrigerant acquisitions, thereby achieving effective utilization of the space of the heat exchanger. When the heat exchanger is in different working modes, at least part of the heat exchanger is in a working state, thereby helping to improve the space utilization of the air-conditioning device.

[0008] Optionally, the first heat exchange chamber and the second heat exchange chamber are stacked along a first direction, and the first direction is parallel to the thickness direction of the shell.

[0009] In the above scheme, the first heat exchange chamber and the second heat exchange chamber are stacked, which can further improve the compactness of the structure, help reduce the occupied space, and improve space utilization. At the same time, when the first heat exchange chamber and the second heat exchange chamber are in the same working mode, it helps to improve the overall working efficiency of the heat exchanger. When the first heat exchange chamber and the second heat exchange chamber are in different working modes or only one of them is working, a high space utilization can still be guaranteed.

[0010] In the second aspect, an embodiment of the present application provides an air-conditioning device for a vehicle, comprising: a shell, an air inlet end, an air outlet end and the heat exchanger in the above embodiment; the shell has a first accommodating space; there are multiple air outlet ends, and along a first direction, the air inlet end and the multiple air outlet ends are arranged on both sides of the shell; the heat exchanger in the above embodiment is arranged in the first accommodating space and is located between the air inlet end and the multiple air outlet ends.

[0011] In the above scheme, the heat exchanger in the above embodiment is arranged in the first accommodation space, which can more effectively utilize the first accommodation space in the shell, so that the air-conditioning device can use less space to simultaneously undertake different heat exchange tasks, thereby performing efficient heat exchange in a limited space, and improving the space utilization rate of the air-conditioning device. At the same time, the heat exchanger in the above embodiment is located between the air inlet end and multiple air outlet ends, and the airflow entering the air inlet end can directly pass through the heat exchanger for heat exchange, so that when the heat exchanger is in different working modes, heat exchange can still be performed directly, reducing the need for additional gas paths, thereby helping to improve the space utilization rate of the air-conditioning device.

[0012] Optionally, the air conditioning device further comprises a first connecting pipeline, a second connecting pipeline, a third connecting pipeline and a fourth connecting pipeline, one end of the first connecting pipeline is connected to the first opening, one end of the second connecting pipeline is connected to the second opening, one end of the third connecting pipeline is connected to the fourth opening, and one end of the fourth connecting pipeline is connected to the third opening;

[0013] The air conditioning device also includes a first fixing block and a second fixing block, the other ends of the first connecting pipeline and the second connecting pipeline are fixed to the first fixing block, and the other ends of the third connecting pipeline and the fourth connecting pipeline are fixed to the second fixing block.

[0015] Optionally, the air inlet end includes a fresh air inlet and an indoor air inlet, the fresh air inlet is connected to the external space, and the indoor air inlet is connected to the passenger compartment space of the vehicle.

[0016] In the above scheme, the fresh air inlet and indoor air inlet set up separately can respectively play the role of conveying outdoor air and conveying indoor air, so that the outdoor wind and indoor wind have independent air inlets respectively, reducing the probability of interference between the outdoor wind and indoor wind airflow, thereby reducing the probability of heat exchange between the outdoor wind and the indoor wind.

[0017] Optionally, the air conditioning device also includes an air guide structure, which is arranged in the shell, and has a fresh air channel and an indoor air channel. The fresh air channel can selectively guide the fresh air from the fresh air inlet to the heat exchanger, and the indoor air channel can selectively guide the indoor air from the indoor air inlet to the heat exchanger.

[0018] In the above scheme, the air guide structure provides a clear air inlet path for the air conditioning system, improves the air flow transmission efficiency, and thus helps to improve the heat exchange efficiency. The fresh air channel and the indoor air channel provide independent air flow paths for the outdoor wind and the indoor wind respectively, thereby reducing the probability of interference between the air flows of the outdoor wind and the indoor wind, thereby reducing the probability of heat exchange between the outdoor wind and the indoor wind, and at the same time ensuring that the air conditioning system obtains air flows with different heat for heat exchange.

[0019] Optionally, the air guide structure includes a second shell, a first blocking block and a second blocking block, the shell defines a fresh air channel and an indoor air channel, the first blocking block is movably disposed on the shell to close or open the fresh air channel, and the second blocking block is movably disposed on the shell to close or open the indoor air channel.

[0020] In the above scheme, the first blocking block is used to close or open the fresh air channel, thereby realizing the input control of outdoor wind in the air-conditioning system, and the second blocking block is used to close or open the indoor wind channel, thereby realizing the input control of indoor wind, so that the air-conditioning system can perform heat exchange on the indoor wind or outdoor wind respectively, thereby reducing the probability of heat exchange between outdoor wind and indoor wind, which helps to improve the heat exchange effect of indoor wind or outdoor wind.

[0023] In the above scheme, by rotating the adjustment plate, the air flow entering the heater can be accurately controlled, thereby achieving fine adjustment of the air flow at different air outlets. When the temperature of the air flow needs to be changed, the air flow can be directed to the heater for heat exchange through the adjustment plate, and then the air flow can be heat exchanged according to the different heat exchange capacities of different heat exchangers, further improving space utilization.

[0025] In the above scheme, the third opening is connected to the sixth opening, so that the refrigerant can flow between the outdoor heat exchanger and the second heat exchange chamber. The fourth opening can be selectively connected to one of the inlet and outlet of the compressor, and then under the action of the compressor, the refrigerant flow direction between the outdoor heat exchanger and the second heat exchange chamber can be changed, so that refrigerant of different temperatures can flow into the second heat exchange chamber, thereby changing the working mode of the second heat exchange chamber. The second opening can be selectively connected to the inlet of the compressor, and the first opening can be selectively connected to the sixth opening and the third opening, so that the first heat exchange chamber can selectively work when the second heat exchange chamber has a different working mode, thereby further forming a working mode with different overall effects, thereby improving the space utilization efficiency.

[0026] Optionally, the fifth opening is selectively connected to the outlet of the compressor through the third valve body, and the fifth opening is selectively connected to the inlet of the compressor through the first valve body;

The second heat exchange chamber can be selectively connected to the inlet or outlet of the compressor through the fourth valve body and the fifth valve body, thereby changing the refrigerant flow direction between the second heat exchange chamber and the compressor, and then changing the working mode of the second heat exchange chamber, which helps to improve space utilization. The second valve body can selectively connect the first heat exchange chamber with the inlet of the compressor, thereby controlling the flow of refrigerant between the first heat exchange chamber and the compressor, and then switching the state of the first heat exchange chamber between working and non-working.

[0069] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0071] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0072] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

[0075] With the development and growth of automobiles, the application scenarios of automobiles are becoming more and more extensive, and the functions of automobiles are also becoming diversified. As one of the important internal functions, car air conditioning has a direct impact on the driver's experience of using the vehicle.

[0076] However, in the related art, the air-conditioning system used in the vehicle requires separate design of cooling pipes and heating pipes to achieve the regulation of the temperature inside the vehicle. The heat causes the overall space occupied to be large. Therefore, how to improve the space utilization of the air-conditioning system is a technical problem that needs to be solved today.

[0077] In view of this, in order to improve the space utilization rate of the air-conditioning device, the embodiment of the present application discloses a heat exchanger 400 for the air-conditioning device, please refer to Figure 1 , including a shell 401, and the shell 401 has a first heat exchange chamber 411 and a second heat exchange chamber 421 inside.

[0078] It is understandable that the first heat exchange chamber 411 and the second heat exchange chamber 421 can be integrally formed inside the shell 401, or can be formed as a whole with the shell 401 by plugging or fixing with screws, and the present application does not limit this.

[0079] The first heat exchange chamber 411 and the second heat exchange chamber 421 are independent of each other, so that the first heat exchange chamber 411 and the second heat exchange chamber 421 do not interfere with each other when working separately. The first heat exchange chamber 411 and the second heat exchange chamber 421 can perform independent temperature adjustment and refrigerant flow control as needed, so that the heat exchanger 400 can more flexibly realize different working modes, thereby improving the space utilization inside the shell 401.

[0080] The shell 401 has a first opening 412 and a second opening 413, both of which are connected to the first heat exchange chamber 411. The first opening 412 and the second opening 413 respectively connect the first heat exchange chamber 411 with the air-conditioning device, so that the refrigerant can flow between the first heat exchange chamber 411 and the air-conditioning device through the first opening 412 and the second opening 413.

[0081] The shell 401 also has a third opening 422 and a fourth opening 423, both of which are connected to the second heat exchange chamber 421. The third opening 422 and the fourth opening 423 respectively connect the second heat exchange chamber 421 with the air-conditioning device, so that the refrigerant can flow between the second heat exchange chamber 421 and the air-conditioning device through the third opening 422 and the fourth opening 423.

[0082] The air conditioning device is suitable for inputting refrigerant of the same temperature into the first heat exchange chamber 411 and the second heat exchange chamber 421 so that the first heat exchange chamber 411 and the second heat exchange chamber 421 have the same working mode.

[0083] It can be understood that the first heat exchange chamber 411 and the second heat exchange chamber 421 can obtain refrigerant of the same temperature from other functional components in the air-conditioning device, thereby realizing the same heat exchange process in the first heat exchange chamber 411 and the second heat exchange chamber 421. At this time, the first heat exchange chamber 411 can obtain refrigerant of the same temperature from one of the first opening 412 and the second opening 413, and the second heat exchange chamber 421 can obtain refrigerant of the same temperature from one of the third opening 422 and the fourth opening 423, and have the same working mode.

[0084] For example, the first heat exchange chamber 411 and the second heat exchange chamber 421 obtain refrigerant of the same temperature from the first opening 412 and the third opening 422 respectively. The joint heat exchange effect of the first heat exchange chamber 411 and the second heat exchange chamber 421 helps to improve the heat exchange efficiency of the heat exchanger 400 and improve the heat exchange effect of the heat exchanger 400.

[0085] The air conditioning device is also suitable for inputting refrigerants of different temperatures into the first heat exchange chamber 411 and the second heat exchange chamber 421 or inputting refrigerants into one of the first heat exchange chamber 411 and the second heat exchange chamber 421 so that the first heat exchange chamber 411 and the second heat exchange chamber 421 have different working modes.

[0086] It can be understood that the first heat exchange chamber 411 and the second heat exchange chamber 421 can obtain refrigerants of different temperatures from other functional components in the air-conditioning device, thereby realizing different heat exchange processes in the first heat exchange chamber 411 and the second heat exchange chamber 421. At this time, the first heat exchange chamber 411 can obtain refrigerants of different temperatures from one of the first opening 412 and the second opening 413, and the second heat exchange chamber 421 can obtain refrigerants of different temperatures from one of the third opening 422 and the fourth opening 423, and have different working modes, which work together to form a new working mode of the heat exchanger 400, such as dehumidification.

[0087] For example, the first heat exchange chamber 411 and the second heat exchange chamber 421 obtain refrigerants of different temperatures through the first opening 412 and the fourth opening 423 respectively. Through the different heat exchange effects of the first heat exchange chamber 411 and the second heat exchange chamber 421, more different heat exchange processes can be carried out in a limited space, thereby helping to improve the space utilization of the heat exchanger 400.

[0088] In addition, one of the first heat exchange chamber 411 and the second heat exchange chamber 421 can independently obtain refrigerant from other functional components in the air-conditioning device, thereby further increasing the working modes of the heat exchanger 400 and further improving space utilization.

[0089] For example, the second heat exchange chamber 421 obtains refrigerant through the fourth opening 423 to realize one working mode, or the first heat exchange chamber 411 obtains refrigerant from the first opening 412, or the second heat exchange chamber 421 obtains refrigerant from the third opening 422 to realize another working mode.

[0090] In the above scheme, the first heat exchange chamber 411 and the second heat exchange chamber 421 can be in different working modes according to the different refrigerant temperatures or the different simultaneous refrigerant acquisitions, thereby achieving effective utilization of the space of the heat exchanger 400. When the heat exchanger 400 is in different working modes, at least part of the heat exchanger 400 is in a working state, which helps to improve the space utilization of the air-conditioning device.

[0091] That is to say, by designing that the first opening 412 can be selectively opened and the flow direction between the third opening 422 and the fourth opening 423 can be variable, the first heat exchange chamber 411 and the second heat exchange chamber 421 can each obtain the corresponding refrigerant, thereby generating different or the same working modes, thereby forming a variety of working modes of the heat exchanger 400, reducing the additional space occupied by the heat exchanger 400 and improving space utilization.

[0092] In other embodiments, please refer to Figure 2 , along a first direction X, the first heat exchange chamber 411 and the second heat exchange chamber 421 are stacked, and the first direction is parallel to the thickness direction of the shell 401 .

[0093] In the above scheme, the first heat exchange chamber 411 and the second heat exchange chamber 421 are stacked, which can further improve the compactness of the structure, help reduce the occupied space, and improve space utilization. At the same time, when the first heat exchange chamber 411 and the second heat exchange chamber 421 are in the same working mode, it helps to improve the overall working efficiency of the heat exchanger 400. When the first heat exchange chamber 411 and the second heat exchange chamber 421 are in different working modes or only one of them is working, a high space utilization can still be guaranteed.

[0094] That is to say, by stacking the first heat exchange chamber 411 and the second heat exchange chamber 421, the space inside the outer shell 401 can be more effectively utilized, and the first heat exchange chamber 411 and the second heat exchange chamber 421 can respectively undertake different heat exchange tasks. The multi-stage heat exchange method can make more effective use of the space and improve the heat exchange efficiency.

[0095] In addition, the two stacked heat exchange chambers can form a more reasonable temperature gradient, so that the fluid can transfer heat more evenly when flowing through the heat exchanger 400, thereby improving the overall heat exchange effect.

[0096] As an example, the first heat exchange chamber 411 and the second heat exchange chamber 421 are integrally formed, which further improves the integration of the heat exchanger 400, and the first heat exchange chamber 411 and the second heat exchange chamber 421 can respectively play different heat exchange roles, thereby improving the overall space utilization.

[0097] In the second aspect, the present application embodiment discloses an air conditioning device for a vehicle, please refer to Figure 2 , comprising a shell 100, an air inlet end 200, an air outlet end 300 and a heat exchanger 400 in any one of the above embodiments.

[0098] The shell 100 has a first accommodating space 110. It can be understood that the accommodating space can accommodate the heat exchanger 400 and provide a gas flow path, thereby achieving efficient heat exchange in a limited space and helping to reduce occupied space.

[0099] There are multiple air outlet ends 300, and the multiple air outlet ends 300 can respectively play the role of providing gas flow paths, thereby facilitating the integration of more gas flow paths.

[0100] Along the first direction X, the air inlet end 200 and multiple air outlet ends 300 are arranged on both sides of the shell 100. It can be understood that the air inlet end 200 and the air outlet end 300 can respectively play the role of air intake and air outlet on both sides of the shell 100, thereby providing a smoother gas flow path for the airflow, which helps to save the space occupied by the shell 100.

[0101] The heat exchanger 400 is arranged in the first accommodating space 110 and is located between the air inlet end 200 and the multiple air outlet ends 300. The heat exchanger 400 can exchange heat for the air flow between the air inlet end 200 and the multiple air outlet ends 300, so that the air flow in the gas flow path corresponding to different air outlet ends 300 can share the heat exchanger 400, thereby improving space utilization.

[0102] In the above scheme, the heat exchanger 400 in the above embodiment is arranged in the first accommodating space 110, which can more effectively utilize the first accommodating space 110 in the shell, so that the air-conditioning device can use less space to simultaneously undertake different heat exchange tasks, thereby performing efficient heat exchange in a limited space and improving the space utilization of the air-conditioning device.

[0103] That is to say, when the air conditioning device is in different working modes, at least part of the heat exchanger 400 is in working state, which reduces the probability of idle space and improves space utilization.

[0104] At the same time, the heat exchanger 400 in the above embodiment is located between the air inlet end 200 and the multiple air outlet ends 300. The airflow entering the air inlet end 200 can directly pass through the heat exchanger 400 for heat exchange, so that when the heat exchanger 400 is in different working modes, heat exchange can still be performed directly, reducing the need for additional gas paths, thereby helping to improve the space utilization of the air-conditioning device.

[0105] In other embodiments, please refer to Figure 1 The air conditioning device also includes a first connecting pipeline 430, a second connecting pipeline 440, a third connecting pipeline 450 and a fourth connecting pipeline 460. It can be understood that the first connecting pipeline 430, the second connecting pipeline 440, the third connecting pipeline 450 and the fourth connecting pipeline 460 can all play the role of circulating refrigerant, thereby providing a clear flow path for the refrigerant.

[0106] One end of the first connecting pipe 430 is connected to the first opening 412, and one end of the second connecting pipe 440 is connected to the second opening 413. That is, the first connecting pipe 430 and the second connecting pipe 440 are connected to the first heat exchange chamber 411 through the first opening 412 and the second opening 413 respectively, thereby providing a clear flow path for the refrigerant in the first heat exchange chamber 411.

[0107] It is understandable that the first connecting pipeline 430 and the second connecting pipeline 440 can both play the role of circulating the refrigerant in the first heat exchange chamber 411 to facilitate the circulation of the refrigerant in the first heat exchange chamber 411, thereby helping the first heat exchange chamber 411 to achieve more heat exchange effects.

[0108] One end of the third connecting pipe 450 is connected to the fourth opening 423, and one end of the fourth connecting pipe 460 is connected to the third opening 422; that is, the third connecting pipe 450 and the fourth connecting pipe 460 are connected to the second heat exchange chamber through the fourth opening 423 and the third opening 422 respectively, thereby providing a clear flow path for the refrigerant in the second heat exchange chamber.

[0109] It is understandable that the third connecting pipeline 450 and the fourth connecting pipeline 460 can both play the role of circulating the refrigerant in the second heat exchange chamber to facilitate the circulation of the refrigerant in the second heat exchange chamber, thereby helping the second heat exchange chamber to achieve more heat exchange effects.

[0110] The air conditioning device also includes a first fixing block 510 and a second fixing block 520. It can be understood that the first fixing block 510 and the second fixing block 520 can be fixedly arranged on the shell 100, and can be fixed by welding, bolting, or clamping, and the present application does not limit this.

[0111] The other end of the first connecting pipeline 430 and the other end of the second connecting pipeline 440 are fixed to the first fixing block 510. It can be understood that the first connecting pipeline 430 and the second connecting pipeline 440 can be fixed by the first fixing block 510, thereby improving the reliability of the first connecting pipeline 430 and the second connecting pipeline 440.

[0112] The other end of the third connecting pipeline 450 and the other end of the fourth connecting pipeline 460 are fixed to the second fixing block 520. It can be understood that the third connecting pipeline 450 and the fourth connecting pipeline 460 can be fixed by the second fixing block 520, thereby improving the reliability of the third connecting pipeline 450 and the fourth connecting pipeline 460.

[0113] Please refer to Figure 2 and Figure 3 Along the second direction Y, the first fixing block 510 and the second fixing block 520 are arranged at intervals and are respectively located on both sides of the heat exchanger 400, and the first direction X is perpendicular to the second direction Y.

[0114] In the above solution, the first fixing block 510 and the second fixing block 520 are arranged at intervals, which can not only reduce the probability of mutual influence between the refrigerants in the first heat exchange chamber 411 and the second heat exchange chamber, but also effectively utilize the space and further improve the compactness of the structure.

[0115] In other embodiments, please refer to Figure 4 The air inlet end 200 includes a fresh air inlet 210 and an indoor air inlet 220. The fresh air inlet 210 is connected to the external space, and the indoor air inlet 220 is connected to the passenger compartment space of the vehicle.

[0116] In the above scheme, the fresh air inlet 210 and the indoor air inlet 220 are respectively arranged to transport outdoor air and indoor air respectively, so that the outdoor wind and the indoor wind have independent air inlets respectively, reducing the probability of interference between the outdoor wind and the indoor wind airflow, thereby reducing the probability of heat exchange between the outdoor wind and the indoor wind.

[0117] It can be understood that the airflow in the space inside the passenger compartment can enter the air-conditioning system from the indoor air inlet 220, and the airflow in the outside space can enter the air-conditioning system from the fresh air inlet 210, so that the air-conditioning system can perform heat exchange on airflows with different heat respectively and transport them to different positions as needed. For example, the airflow in the outside space can be transported to the front windshield, and the airflow in the space inside the passenger compartment can be transported back to the passenger compartment.

[0118] In other embodiments, please refer to Figure 4The air conditioning device also includes an air guide structure 120, which is arranged in the shell 100. The air guide structure 120 has a fresh air channel and an indoor air channel. The fresh air channel can selectively guide the fresh air from the fresh air inlet to the heat exchanger 400, and the indoor air channel can selectively guide the indoor air from the indoor air inlet to the heat exchanger 400.

[0119] In the above scheme, the air guide structure 120 provides a clear air inlet path for the air-conditioning system, improves the air flow transmission efficiency, and thus helps to improve the heat exchange efficiency. The fresh air channel and the indoor air channel provide independent air flow paths for the outdoor wind and the indoor wind respectively, thereby reducing the probability of interference between the outdoor wind and the indoor wind airflow, thereby reducing the probability of heat exchange between the outdoor wind and the indoor wind, and at the same time ensuring that the air-conditioning system obtains airflows with different heat amounts for heat exchange.

[0120] In other embodiments, please refer to Figure 4 The air guide structure 120 includes a second shell 121, a first blocking block and a second blocking block. The shell 121 defines a fresh air channel and an indoor air channel. The first blocking block is movably disposed on the shell 121 to close or open the fresh air channel, and the second blocking block is movably disposed on the shell 121 to close or open the indoor air channel.

[0121] In the above scheme, the first blocking block is used to close or open the fresh air channel, thereby realizing the input control of outdoor wind in the air-conditioning system, and the second blocking block is used to close or open the indoor wind channel, thereby realizing the input control of indoor wind, so that the air-conditioning system can perform heat exchange on the indoor wind or outdoor wind respectively, thereby reducing the probability of heat exchange between outdoor wind and indoor wind, which helps to improve the heat exchange effect of indoor wind or outdoor wind.

[0122] It can be understood that the first blocking block and the second blocking block can respectively block the corresponding channels or open the corresponding channels at the same time to input different airflows into the air-conditioning system, which helps to exchange heat between airflows with different heat in a limited space and improve the space utilization of the air-conditioning system.

[0123] In other embodiments, please refer to Figure 1 The air conditioning device also includes a regulating mechanism 800 and a heater 400a. Along the first direction X, the heater 400a and the heat exchanger 400 are opposite and spaced apart. The regulating mechanism 800 is arranged between the heater 400a and the heat exchanger 400. It can be understood that the regulating mechanism 800 can play a role in regulating the flow of gas, thereby adjusting the gas path flowing from the heat exchanger 400 to the heater 400a, so that the gas flow path of the air conditioning system is adjustable, thereby improving its applicability.

[0124] Among them, there are multiple adjustment mechanisms 800, and the multiple adjustment mechanisms 800 correspond one-to-one to the multiple air outlet ends 300, so that each air outlet end 300 has an independent adjustment mechanism 800, so that the gas flow paths of each air outlet end 300 do not affect each other, thereby realizing precise control of the air flow of multiple air outlet ends 300 in a compact space.

[0125] Each regulating mechanism 800 has an regulating plate 801 , which is rotatably disposed on the regulating mechanism 800 , so that the wind entering from the air inlet end 200 can selectively pass through the heat exchanger 400 to be directed to the corresponding air outlet end 300 .

[0126] In the above scheme, by rotating the adjustment plate 801, the air flow passing through the heater 400a can be accurately controlled, thereby achieving fine adjustment of the air flow at different air outlets 300, which is more flexible and accurate than traditional single air flow control and can meet different air flow requirements in different areas or at different times.

[0127] When the temperature of the airflow needs to be changed, the airflow can be directed to the heater 400a for heat exchange through the adjustment plate 801, and then the airflow is heat exchanged according to the different heat exchange capacities of the heat exchanger 400 and the heater 400a, further improving space utilization.

[0128] In addition, the air flow can be adjusted according to actual needs. For example, in areas where less cooling / heating is required, the air flow can be reduced by reducing the opening of the adjustment plate 801, thereby reducing energy consumption. This on-demand adjustment method helps to improve the energy efficiency of the entire air conditioning system.

[0129] In addition, the one-to-one correspondence between the multiple adjustment mechanisms 800 and the multiple air outlets 300 enables the air conditioning system to be flexibly adjusted according to different usage scenarios and needs. For example, in areas where rapid cooling or heating is required, the opening of the corresponding adjustment mechanism 800 can be increased to increase the air flow; while in areas where a constant temperature is required, the opening can be reduced to maintain a stable air flow.

[0130] In a third aspect, the present application provides a thermal management system for a vehicle. Fig. 9 , including a compressor 600, an outdoor heat exchanger 700 and the heat exchanger 400 in any of the above embodiments. It can be understood that the compressor 600 and the outdoor heat exchanger 700 can respectively play the role of heat exchange. When the refrigerant passes through the compressor 600 or the outdoor heat exchanger 700, the heat carried can be changed to change its own temperature, thereby achieving different heat exchange effects.

[0131] The outdoor heat exchanger 700 has a fifth opening 710 and a sixth opening 720. The fifth opening 710 is connected to one of the inlet and the outlet of the compressor 600. It can be understood that the refrigerant can flow between the compressor 600 and the outdoor heat exchanger 700, so as to realize heat exchange at different positions. During cooling, the outdoor heat exchanger 700 can effectively transfer the heat absorbed indoors to the outdoors.

[0132] The sixth opening 720 is connected to the third opening 422. It can be understood that the refrigerant can flow between the second heat exchange chamber 421 and the outdoor heat exchanger 700 through the third opening 422 and the sixth opening 720, thereby providing a flow path for the refrigerant in the second heat exchange chamber 421 to exchange heat with the outdoor, so that refrigerants of different temperatures can flow into the second heat exchange chamber 421, so that the second heat exchange chamber 421 can perform different heat exchanges under the action of refrigerants of different temperatures, thereby further improving the space utilization efficiency.

[0133] The first opening 412 is connected to the sixth opening 720. It can be understood that the refrigerant can flow between the first heat exchange chamber 411 and the outdoor heat exchanger 700 through the first opening 412 and the sixth opening 720, thereby providing a flow path for the refrigerant in the first heat exchange chamber 411 to exchange heat with the outdoor, thereby changing the heat carried by the refrigerant, so that the first heat exchange chamber 411 can perform different heat exchanges under the action of refrigerants with different heat amounts, thereby further improving the space utilization efficiency.

[0134] The first opening 412 can be selectively connected to the sixth opening 720 and the third opening 422. It can be understood that the first opening 412 and the third opening 422 are both connected to the sixth opening 720 of the outdoor heat exchanger 700 to form a circulation channel for the refrigerant, so that the refrigerant in the first heat exchange chamber 411 and the second heat exchange chamber 421 can circulate, which helps the first heat exchange chamber 411 and the second heat exchange chamber 421 to produce different heat exchange effects, thereby improving the space utilization efficiency.

[0135] When the first opening 412 and the third opening 422 are connected, the refrigerant can flow between the first heat exchange chamber 411 and the second heat exchange chamber 421, which helps the first heat exchange chamber 411 and the second heat exchange chamber 421 to produce different heat exchange effects, thereby improving space utilization efficiency.

[0136] The second opening 413 is selectively connected to the inlet of the compressor 600. It can be understood that the refrigerant can flow between the first heat exchange chamber 411 and the compressor 600, so that the refrigerant after heat exchange in the first heat exchange chamber 411 can flow out in time, and the refrigerant of different temperatures can quickly flow into the first heat exchange chamber 411, so that the first heat exchange chamber 411 maintains efficient heat exchange.

[0137] The fourth opening 423 can be selectively connected to one of the inlet and the outlet of the compressor 600. It can be understood that the refrigerant can flow between the second heat exchange chamber 421 and the compressor 600. When the fourth opening 423 is connected to the inlet of the compressor 600, the refrigerant in the second heat exchange chamber 421 can enter the compressor 600 and become a high-temperature and high-pressure state after absorbing heat. Then, through the action of the compressor 600, the refrigerant in the high-temperature and high-pressure state is transported to the outdoor heat exchanger 700. After releasing heat at the outdoor heat exchanger 700, the refrigerant can return to the second heat exchange chamber 421 to absorb heat.

[0138] When the fourth opening 423 is connected to the outlet of the compressor 600, the refrigerant that has become a high-temperature and high-pressure state in the compressor 600 can enter the second heat exchange chamber 421, and after releasing heat in the second heat exchange chamber 421, it is transported to the outdoor heat exchanger 700 through the action of the compressor 600. After absorbing heat in the outdoor heat exchanger 700, the refrigerant can return to the compressor 600 and become a high-temperature and high-pressure state, and finally re-enter the second heat exchange chamber 421 to release heat.

[0139] In the above scheme, the third opening 422 is connected to the sixth opening 720, so that the refrigerant can flow between the outdoor heat exchanger 700 and the second heat exchange chamber 421, and the fourth opening 423 can be selectively connected to one of the inlet and outlet of the compressor 600, and then under the action of the compressor 600, the refrigerant flow direction between the outdoor heat exchanger 700 and the second heat exchange chamber 421 can be changed, so that refrigerants of different temperatures can flow into the second heat exchange chamber 421, thereby changing the working mode of the second heat exchange chamber 421.

[0140] The second opening 413 can be selectively connected to the inlet of the compressor 600, and the first opening 412 can be selectively connected to the sixth opening 720 or the third opening 422, so that the first heat exchange chamber 411 can selectively work when the second heat exchange chamber 421 has a different working mode, thereby further forming a working mode with different overall effects, thereby improving space utilization efficiency.

[0141] As an example, in cooling mode, refer to Fig. 9 The refrigerant exchanges heat with the circulating air in at least one of the first heat exchange chamber 411 and the second heat exchange chamber 421, taking away part of the heat in the air to achieve a cooling effect. Then, the refrigerant is compressed by the compressor 600 to become a high-temperature and high-pressure refrigerant. The heat absorbed by the refrigerant is transferred to the outdoors in the outdoor heat exchanger 700, and the refrigerant becomes a liquid refrigerant at room temperature and high pressure, and then enters the first heat exchange chamber 411 and the second heat exchange chamber 421. The refrigerant is depressurized and cooled in the first heat exchange chamber 411 and the second heat exchange chamber 421, so that the refrigerant circulates in the system and achieves a cooling effect.

[0142] As an example, in heating mode, please refer to Fig.10 The refrigerant exchanges heat with the circulating air in the second heat exchange chamber 421, releasing heat into the air to achieve a heating effect, and then the refrigerant enters the outdoor heat exchanger 700 through the fourth opening 423 and the sixth opening 720, absorbs heat at the outdoor heat exchanger, and then enters the compressor 600 through the fifth opening 710 and the inlet of the compressor. The refrigerant is then compressed by the compressor 600 into a high-temperature and high-pressure refrigerant, and flows out of the opening of the compressor 600 and returns to the second heat exchange chamber 421 through the fourth opening 423 to release heat.

[0143] As an example, see Fig.11 , when the third opening 422 is connected to the sixth opening 720 and the first opening 412 at the same time, and the fourth opening 423 is connected to the outlet of the compressor 600, and the second opening 413 and the fifth opening 710 are connected to the inlet of the compressor 600 at the same time, the flow path of the refrigerant is that after the refrigerant releases heat at the second heat exchange chamber 421, it flows out of the second heat exchange chamber 421 through the third opening 422, and then enters the outdoor heat exchanger 700 and the first heat exchange chamber 411 through the sixth opening 720 and the first opening 412 respectively, so that the refrigerant can be in the outdoor heat exchanger 700 and the first heat exchange chamber 411 The heat exchange chamber 411 absorbs heat, and then the refrigerant flows out of the outdoor heat exchanger 700 and the first heat exchange chamber 411 through the fifth opening 710 and the second opening 413 respectively, and enters the compressor 600 through the inlet of the compressor 600, and is compressed into a high-temperature and high-pressure refrigerant under the action of the compressor 600. Finally, the high-temperature and high-pressure refrigerant flows out from the outlet of the compressor through the fourth opening 423 and re-enters the second heat exchange chamber 421 to release heat, thereby achieving heating of the second heat exchange chamber 421 and cooling of the first heat exchange chamber 411, forming a new heat exchanger working mode, such as dehumidification.

[0144] In other embodiments, the fifth opening 710 is selectively connected to the outlet of the compressor 600 through the third valve body 603. It can be understood that when the third valve body 603 is turned on, the fifth opening 710 is connected to the outlet of the compressor 600. After the refrigerant in the compressor 600 is compressed to a high temperature and high pressure state, it can enter the outdoor heat exchanger 700 to release heat.

[0145] The fifth opening 710 is selectively connected to the inlet of the compressor 600 through the first valve body 601. It can be understood that when the first valve body 601 is turned on, the fifth opening 710 is connected to the inlet of the compressor 600. After heat exchange at the outdoor heat exchanger 700, the refrigerant can re-enter the compressor 600 and be compressed into a high temperature and high pressure state.

[0146] In the above scheme, the outdoor heat exchanger 700 can be selectively connected to the inlet or outlet of the compressor 600 through the third valve body 603 and the first valve body 601, thereby changing the refrigerant flow direction between the outdoor heat exchanger 700 and the compressor 600, and then changing the working mode of the outdoor heat exchanger 700, which helps to improve space utilization.

[0147] A second valve body 602 is arranged between the second opening 413 and the inlet of the compressor 600. It can be understood that when the second valve body 602 is turned on, the second opening 413 is connected to the inlet of the compressor 600, and the refrigerant can enter the compressor 600 and be compressed into a high temperature and high pressure state after heat exchange in the first heat exchange chamber 411.

[0148] A fourth valve body 604 is arranged between the fourth opening 423 and the outlet of the compressor 600. It can be understood that when the fourth valve body 604 is turned on, the fourth opening 423 is connected to the outlet of the compressor 600. After the refrigerant in the compressor 600 is compressed to a high temperature and high pressure state, it can enter the second heat exchange chamber 421 to release heat.

[0149] A fifth valve body 605 is arranged between the fourth opening 423 and the inlet of the compressor 600. It can be understood that when the fifth valve body 605 is turned on, the fourth opening 423 is connected to the inlet of the compressor, and the refrigerant can enter the compressor 600 and be compressed into a high temperature and high pressure state after heat exchange in the second heat exchange chamber 421.

[0150] As an example, two ends of the fifth valve body 605 are connected to the second valve body 602 and the fourth opening 423 , respectively, and the fifth valve body 605 and the second opening 413 are connected to the same end of the second valve body 602 .

[0151] That is to say, when the fifth valve body 605 and the second valve body 602 are turned on at the same time, the inlet of the compressor is connected, and the refrigerant can enter the compressor 600 and be compressed into a high temperature and high pressure state after heat exchange in the second heat exchange chamber 421.

[0152] This optimizes the pipeline and helps improve space utilization.

[0153] In the above scheme, the second heat exchange chamber 421 can be selectively connected to the inlet or outlet of the compressor 600 through the fourth valve body 604 and the fifth valve body 605, thereby changing the refrigerant flow direction between the second heat exchange chamber 421 and the compressor 600, and then changing the working mode of the second heat exchange chamber 421, which helps to improve space utilization.

[0154] The second valve body 602 can selectively connect the first heat exchange chamber 411 with the inlet of the compressor 600, so as to control the flow of refrigerant between the first heat exchange chamber 411 and the compressor 600, and further switch the state of the first heat exchange chamber 411 between working and non-working.

[0155] In other embodiments, the first valve body 601 , the second valve body 602 , the third valve body 603 , the fourth valve body 604 and the fifth valve body 605 are all configured as stop valves.

[0156] In the above scheme, the first valve body 601, the second valve body 602, the third valve body 603, the fourth valve body 604 and the fifth valve body 605 are all constructed as stop valves, so as to realize the opening and closing of the corresponding passages between the first heat exchange chamber 411, the second heat exchange chamber 421, the outdoor heat exchanger 700 and the compressor 600, which helps to ensure the sealing of the remaining passages in different working modes.

[0157] In other embodiments, please refer to Figure 9-11 A first expansion valve 701 is disposed between the sixth opening 720 and the first opening 412 , and a second expansion valve 702 is disposed between the sixth opening 720 and the third opening 422 .

[0158] In the above scheme, the first expansion valve 701 and the second expansion valve 702 can reduce the pressure and temperature of the refrigerant flowing through the first expansion valve 701 and the second expansion valve 702 by half-open throttling, thereby helping to achieve different working modes, thereby helping to improve space utilization.

[0159] In the specific embodiment, please refer to Figure 9-11 A second expansion valve 702 is disposed between the third opening 422 and the sixth opening 720 , the first opening 412 and the third opening 422 are connected to the same end of the second expansion valve 702 , and a first expansion valve 701 is disposed between the first opening 412 and the second expansion valve 702 .

[0160] A second valve body 602 is disposed between the second opening 413 and the inlet of the compressor 600 . The fourth opening 423 and the second opening 413 are connected to the same end of the second valve body 602 . A fifth valve body 605 is disposed between the fourth opening 423 and the second valve body 602 .

[0161] A fourth valve body 604 is disposed between the fourth opening 423 and the outlet of the compressor 600 , a first valve body 601 is disposed between the first opening 710 and the inlet of the compressor 600 , and a third valve body 603 is disposed between the first opening 710 and the outlet of the compressor 600 .

[0162] As an example, the valve body and the openings may be connected via pipelines, and a refrigerant medium flows through the pipelines.

[0163] When cooling, please refer to Fig. 9 The second heat exchange chamber 421 and the first heat exchange chamber 411 can be cooled at the same time, or can be cooled separately as needed. At this time, the fourth valve body 604 and the first valve body 601 are closed, the second valve body 602, the third valve body 603 and the fifth valve body 605 are connected, and the first expansion valve 701 and the second expansion valve 702 are half-open for throttling.

[0164] The following briefly describes the working process during refrigeration, taking the second heat exchange chamber 421 and the first heat exchange chamber 411 working simultaneously as an example.

[0165] Under the action of the compressor 600, the refrigerant flows out of the compressor 600 and passes through the third valve body 603 to enter the outdoor heat exchanger 700 to release heat.

[0166] After releasing heat, the refrigerant flows out of the outdoor heat exchanger 700 and passes through the first expansion valve 701 and the second expansion valve 702 to enter the first heat exchange chamber 411 and the second heat exchange chamber 421 respectively. Since the first expansion valve 701 and the second expansion valve 702 are half-open for throttling, a pressure drop occurs when the refrigerant enters the first heat exchange chamber 411 and the second heat exchange chamber 421, thereby continuing to cool in the first heat exchange chamber 411 and the second heat exchange chamber 421 to realize refrigerant circulation.

[0167] The refrigerant in the second heat exchange chamber 421 enters the compressor 600 through the fifth valve body 605 and the second valve body 602 in sequence after being cooled, and the refrigerant in the first heat exchange chamber 411 enters the compressor 600 through the second valve body 602 after being cooled.

[0168] The working process of the second heat exchange chamber 421 during heating is briefly described below.

[0169] When heating, please refer to Fig.10 , the first heat exchanger does not work, the second heat exchanger releases heat, the second valve body 602, the third valve body 603 and the fifth valve body 605 are closed, the first valve body 601 and the fourth valve body 604 are connected, the second expansion valve 702 is half-open for throttling, and the first expansion valve 701 is fully closed.

[0170] After absorbing heat, the refrigerant flows out of the outdoor heat exchanger 700, passes through the first valve body 601 and enters the compressor 600. Under the action of the compressor 600, the refrigerant flows out of the compressor 600 and passes through the fourth valve body 604 back to the second heat exchange chamber 421 to release heat, thereby realizing the refrigerant circulation.

[0171] After being heated, the refrigerant in the second heat exchange chamber 421 enters the outdoor heat exchanger 700 through the second expansion valve 702. Since the second expansion valve 702 is half-open for throttling, a pressure drop occurs when the refrigerant enters the outdoor heat exchanger 700, thereby performing cooling at the outdoor heat exchanger 700.

[0172] The following briefly describes the working process of the first heat exchange chamber 411 and the second heat exchange chamber 421 during simultaneous cooling and heating.

[0173] When cooling and heating are required at the same time, please refer to Fig.11 The second heat exchange chamber 421 is for cooling and the first heat exchange chamber 411 is for heating. At this time, the third valve body 603 and the fifth valve body 605 are closed, the first valve body 601, the second valve body 602 and the third valve body 603 are connected, and the first expansion valve 701 and the second expansion valve 702 are half-open for throttling.

[0174] The refrigerant cooled in the outdoor heat exchanger 700 enters the compressor 600 through the first valve body 601. Under the action of the compressor 600, it flows out of the compressor 600 and returns to the second heat exchange chamber 421 through the fourth valve body 604 to release heat, thereby realizing the refrigerant circulation.

[0175] The refrigerant cooled in the first heat exchange chamber 411 enters the compressor 600 through the second valve body 602. Under the action of the compressor 600, it flows out of the compressor 600 and returns to the second heat exchange chamber 421 through the fourth valve body 604 to release heat, thereby realizing the refrigerant circulation.

[0176] A portion of the refrigerant in the second heat exchange chamber 421 enters the outdoor heat exchanger 700 through the second expansion valve 702 . Since the second expansion valve 702 is half-open for throttling, a pressure drop occurs when the refrigerant enters the outdoor heat exchanger 700 , thereby performing cooling at the outdoor heat exchanger 700 .

[0177] Another part of the refrigerant in the second heat exchange chamber 421 enters the first heat exchange chamber 411 through the first expansion valve 701. Since the first expansion valve 701 is half-open for throttling, a pressure drop occurs when the refrigerant enters the first heat exchange chamber 411, thereby performing cooling in the first heat exchange chamber 411.

[0178] As an example, a gas-liquid separator is provided at the opening of the compressor 600 to separate the refrigerant into gas and liquid before entering the compressor 600. The first valve body 601 and the second valve body 602 are connected to the same end of the gas-liquid separator and are respectively arranged at the two ends of the gas-liquid separator with the compressor 600.

[0179] In other embodiments, please refer to Figure 2 The air conditioning device includes a plurality of adjustment mechanism groups 810, and the plurality of adjustment mechanism groups 810 are arranged along the third direction Z. Each adjustment mechanism group 810 includes a plurality of adjustment mechanisms 800 arranged along the second direction Y.

[0180] It can be understood that multiple adjustment mechanism groups 810 can respectively play the role of adjusting the airflow, that is, multiple adjustment mechanism groups 810 can respectively form gas flow paths to guide the airflow to different positions, so that after the air-conditioning device takes in air, the airflow can be utilized separately through different gas flow paths, so that the airflow can be adjusted in a variety of ways in a compact space, thereby improving space utilization.

[0181] As an example, in areas that require less cooling / heating, energy consumption can be reduced by reducing the opening of the corresponding regulating mechanism group 810; while in areas that require more cooling / heating, the opening can be increased to meet the demand. By precisely controlling the opening of each regulating mechanism group 810, precise control of the air-conditioning device can be achieved, which helps to improve the energy efficiency of the entire air-conditioning device.

[0182] In other embodiments, please refer to Figure 2 The air conditioning device includes a plurality of air outlet end groups 310, and the plurality of air outlet end groups 310 are arranged along a third direction Z. Each air outlet end group 310 includes a plurality of air outlet ends 300 arranged along a second direction Y. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0183] In the above scheme, since the three directions are perpendicular to each other, this layout can make full use of the three-dimensional space, so that the air-conditioning device can arrange multiple adjustment mechanisms and air outlets 300 in a limited space, further improving space utilization.

[0184] It can be understood that each air outlet end 300 can play the role of discharging air, thereby improving the uniformity of the airflow. At the same time, each adjustment mechanism 800 and the corresponding air outlet end 300 can be selectively cooperated with the heat exchanger 400 to obtain airflows of different temperatures or humidities, thereby reducing the probability of idle space in the air-conditioning device and improving space utilization.

[0185] In other embodiments, please refer to Figure 5 The adjustment mechanism 800 also includes a rotating shaft 802 and a connecting plate 803. The rotating shaft 802 is rotatably disposed on the shell 100. It can be understood that the rotatability of the rotating shaft 802 enables the adjustment mechanism 800 to be flexibly rotated or swung as needed, thereby changing the position or angle of the adjustment plate 801.

[0186] The connecting plate 803 connects the rotating shaft 802 and the adjusting plate 801. It can be understood that the connecting plate 803 can fix the adjusting plate 801 to the rotating shaft 802, and can disperse the force and torque generated by the rotating shaft 802 during the rotation process, thereby preventing the adjusting plate 801 from being deformed or damaged due to uneven force.

[0187] In the above solution, the rotating shaft 802 is connected to the adjusting plate 801 via the connecting plate 803, so as to ensure the synchronous movement between the two and achieve a precise adjustment effect.

[0188] In other embodiments, please refer to Figure 5 The adjustment plate 801 is constructed as an arc plate 801a. It can be understood that the arc plate 801a can guide the airflow to be distributed more evenly. When the airflow flows to the surface of the arc plate 801a, according to the Coanda effect, the airflow will flow along the surface of the arc surface and gradually change the flow direction. This design can reduce the forced turning of the airflow, reduce the probability of airflow impact, and make the airflow more uniform and soft.

[0189] The arc plate 801a protrudes in a direction away from the rotating axis 802. It can be understood that the arc plate 801a protrudes in a direction away from the rotating axis 802, which can further increase the contact area with the airflow, thereby guiding the airflow toward the corresponding air outlet end 300, making the airflow more uniform.

[0190] In addition, the design of the curved plate 801a helps to reduce noise and vibration during the operation of the air conditioning device. When the air flows through the curved plate 801a, its flow is smoother and continuous, reducing the noise generated by the turbulent air flow.

[0191] In other embodiments, please refer to Figure 5 and Figure 8 The multiple regulating mechanism groups 810 include a first regulating mechanism group 811 and a second regulating mechanism group 812. It can be understood that the first regulating mechanism group 811 and the second regulating mechanism group 812 can respectively regulate different gas flow paths to achieve independent regulation of the air flow rates of different gas flow paths, thereby improving the flexibility and adaptability of the air-conditioning device.

[0192] Please refer to Figure 2 and Figure 5 The multiple air outlet end groups 310 include a first air outlet end group 311 and a second air outlet end group 312. It can be understood that the multiple air outlet end groups 310 can send wind to different areas or directions to meet the air supply needs of different positions or spaces.

[0193] The first accommodating space 110 includes a first flow channel group 910, a second flow channel group 920 and a third flow channel 930. It can be understood that by setting up multiple flow channels, a more refined division of the airflow can be achieved, and different flow channels can correspond to different functions or needs, such as heating, cooling, air supply, etc., which will further improve the space utilization and improve the functionality and flexibility of the air-conditioning device.

[0194] The heater 400a is disposed in the third flow channel 930. It can be understood that by disposing the heater 400a in the third flow channel 930, the airflow passing through the flow channel can be heated, so that the system can heat the airflow as needed.

[0195] The first regulating mechanism group 811 is used to guide the airflow proportionally to the inlet of the first flow channel group 910 and the inlet of the third flow channel 930. It can be understood that the first regulating mechanism group 811 can accurately control the distribution ratio of the airflow between the first flow channel group 910 and the third flow channel 930, thereby realizing flexible adjustment of the air flow rate of the two flow channels, reducing the probability of idleness of the internal structure of the air-conditioning device, and improving space utilization.

[0196] The second regulating mechanism group 812 is used to guide the airflow proportionally to the inlet of the third flow channel 930 and the inlet of the second flow channel group 920. It can be understood that the second regulating mechanism group 812 can accurately control the distribution ratio of the airflow between the second flow channel group 920 and the third flow channel 930, thereby realizing flexible adjustment of the air flow rate of the two flow channels, reducing the probability of idleness of the internal structure of the air-conditioning device, and improving space utilization.

[0197] Please refer to Figure 2 The outlet of the first flow channel group 910 is constructed as the first air outlet end group 311, and the outlet of the second flow channel group 920 is constructed as the second air outlet end group 312. It can be understood that by constructing the outlet of the first flow channel group 910 as the first air outlet end group 311 and the outlet of the second flow channel group 920 as the second air outlet end group 312, it can be ensured that the airflow passing through the first flow channel group 910 and the second flow channel group 920 can be smoothly delivered to the designated area or direction, thereby improving the air supply efficiency.

[0198] The outlet of the third flow channel 930 is connected to the outlet of the first flow channel group 910, and the outlet of the third flow channel 930 is connected to the outlet of the second flow channel group 920. It can be understood that by connecting the outlet of the third flow channel 930 with the outlets of the first flow channel group 910 and the second flow channel group 920, the airflows of different flow channels can share the outlet, further improving the space utilization.

[0199] In addition, since the outlet of the third flow channel 930 is connected to the outlets of the first flow channel group 910 and the second flow channel group 920, the system can flexibly mix the heated air with the unheated air to meet different temperature requirements, thereby further improving space utilization.

[0200] In the above scheme, by establishing the first regulating mechanism group 811 and the second regulating mechanism group 812, the system can independently control the airflow distribution of different flow channel groups, so as to accurately adjust the airflow volume of each flow channel according to actual needs. Since the first regulating mechanism group 811 and the second regulating mechanism group 812 can both realize the airflow regulation of two flow channels, the space utilization rate is higher.

[0201] As an example, the third flow channel 930 is provided with a heater 400a, which can be used to heat the air; the first flow channel group 910 and the second flow channel group 920 can be used to directly supply air or be used in conjunction with other processing equipment (such as a cooler), so that the first flow channel group 910, the second flow channel group 920 and the third flow channel 930 respectively realize different functions, reducing the probability of idleness of various components of the air-conditioning device and further improving space utilization.

[0204] The first air outlet group 311 includes a first air outlet 311a and a second air outlet 311b. It can be understood that the two air outlets 300 in the first air outlet group 311 can supply air respectively, so that the system can adjust the direction of air supply as needed.

[0205] The first flow channel group 910 includes a first sub-flow channel 911 and a second sub-flow channel 912. It can be understood that by setting up multiple sub-flow channels, a more refined division of the airflow can be achieved. Different sub-flow channels can correspond to different functions or needs, such as heating, cooling, air supply, etc., which will further improve the space utilization and improve the functionality and flexibility of the air-conditioning device.

[0206] The first regulating mechanism 811a guides the airflow proportionally to the inlet of the first sub-channel 911 and the inlet of the third channel 930 by rotating the regulating plate 801. It can be understood that the first regulating mechanism 811a can accurately control the distribution ratio of the airflow between the first sub-channel 911 and the third channel 930, thereby realizing flexible adjustment of the airflow volume of the two channels, further reducing the probability of idleness of the internal structure of the air-conditioning device, and further improving space utilization.

[0207] The second regulating mechanism 811b guides the airflow proportionally to the inlet of the second sub-channel 912 and the inlet of the third channel 930 by rotating the regulating plate 801. It can be understood that the second regulating mechanism 811b can accurately control the distribution ratio of the airflow between the second sub-channel 912 and the third channel 930, thereby realizing flexible adjustment of the airflow volume of the two channels, further reducing the probability of idleness of the internal structure of the air-conditioning device, and further improving space utilization.

[0208] The second regulating mechanism group 812 includes a third regulating mechanism 812a and a fourth regulating mechanism 812b. It can be understood that the third regulating mechanism 812a and the fourth regulating mechanism 812b can respectively regulate different gas flow paths to achieve independent regulation of the air volume of different gas flow paths, thereby improving the flexibility and adaptability of the air-conditioning device.

[0209] The second air outlet group 312 includes a third air outlet 312a and a fourth air outlet 312b. It is understandable that the two air outlets 300 in the second air outlet group 312 can supply air respectively, so that the system can adjust the direction of air supply as needed.

[0210] Please refer to Figure 6 and Figure 7 The second flow channel group 920 includes a third sub-flow channel 921 and a fourth sub-flow channel 922. It can be understood that by setting up multiple sub-flow channels, a more refined division of the airflow can be achieved. Different sub-flow channels can correspond to different functions or needs, such as heating, cooling, air supply, etc., which will further improve the space utilization and improve the functionality and flexibility of the air-conditioning device.

[0211] The third regulating mechanism 812a guides the airflow proportionally to the inlet of the third sub-channel 921 and the inlet of the third channel 930 by rotating the regulating plate 801. It can be understood that the third regulating mechanism 812a can accurately control the distribution ratio of the airflow between the third sub-channel 921 and the third channel 930, thereby realizing flexible adjustment of the airflow volume of the two channels, further reducing the probability of idleness of the internal structure of the air-conditioning device, and further improving space utilization.

[0212] The fourth regulating mechanism 812b guides the airflow proportionally to the inlet of the fourth sub-channel 922 and the inlet of the third channel 930 by rotating the regulating plate 801. It can be understood that the fourth regulating mechanism 812b can accurately control the distribution ratio of the airflow between the fourth sub-channel 922 and the third channel 930, thereby realizing flexible adjustment of the air flow of the two channels, further reducing the probability of idleness of the internal structure of the air-conditioning device, and further improving space utilization.

[0213] In the above scheme, the first flow channel group 910 and the second flow channel group 920 each include two sub-flow channels (first sub-flow channel 911, second sub-flow channel 912, third sub-flow channel 921 and fourth sub-flow channel 922), so that the system can flexibly adjust the flow channel configuration according to different operating modes and user needs. For example, in summer, the system can lower the indoor temperature by reducing the airflow of the heater 400a; in winter, the indoor temperature can be increased by increasing the airflow passing through the heater 400a.

[0214] In addition, since the accommodation space inside the shell is divided more finely and the airflow can be adjusted jointly between different areas, the space utilization rate of the air conditioning device is further improved.

[0218] In the above scheme, by proportionally directing the airflow to different flow channel groups and heat exchange zone groups, the heat exchange process is optimized.
