It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model.

[0050] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model or its application or use.

[0051] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0052] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0053] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof in subsequent drawings is not required.

[0054] The automotive air conditioning box 100 according to an embodiment of the present utility model will be specifically described below with reference to the accompanying drawings.

[0055] As Figures 1 to 12 shown, the automotive air conditioning box 100 according to an embodiment of the present utility model includes: a box body 10, a first heat exchange core 20, and a second heat exchange core 30.

[0056] Specifically, a air supply channel is provided in the box body 10. The air supply channel includes a first air duct 12 and a second air duct 13. The box body 10 is provided with an air inlet and an air outlet. Among them, the first end of the first air duct 12 and the first end of the second air duct 13 are adapted to communicate with the air inlet, and the second end of the first air duct 12 and the second end of the second air duct 13 are adapted to communicate with the air outlet. The first heat exchange core 20 is disposed in the first air duct 12, and the second heat exchange core 30 is disposed in the second air duct 13.

[0057] In other words, as Figures 1 to 12 shown, the automotive air conditioning box 100 according to an embodiment of the present utility model mainly includes a box body 10, a first heat exchange core 20, and a second heat exchange core 30. Among them, an air supply channel is provided in the box body 10, and the box body 10 is further provided with an air inlet and an air outlet. The air supply channel is located between the air inlet and the air outlet. The air supply channel includes the first air duct 12 and the second air duct 13 arranged side by side. The first air duct 12 can be an upper air duct, and the second air duct 13 can be a lower air duct. The end of the first air duct 12 and the second air duct 13 close to the air inlet is the first end, and the end of the first air duct 12 and the second air duct 13 close to the air outlet is the second end.

[0058] The first end of the first air duct 12 and the first end of the second air duct 13 can be in communication with the air inlet, so that air flow can enter from the first end of the first air duct 12 and the first end of the second air duct 13. The second end of the first air duct 12 and the second end of the second air duct 13 can be in communication with the air outlet, so that air flow can be discharged from the second end of the first air duct 12 and the second end of the second air duct 13.

[0059] As Figures 1 to 12 shown, the first heat exchange core 20 can be fixed to the first air duct 12. When air flow passes through the first air duct 12, the passing air flow can be heat-exchanged through the first heat exchange core 20; the second heat exchange core 30 can be fixed to the second air duct 13. When air flow passes through the second air duct 13, the passing air flow can be heat-exchanged through the second heat exchange core 30, and can be independent of the first heat exchange core 20 without interference.

[0060] Thus, for the automotive air-conditioning box 100 according to the embodiment of the present utility model, by providing a air supply channel including the first air duct 12 and the second air duct 13, the cross-sectional area of the air supply channel is effectively increased. Compared with the existing air-conditioning box with a single air duct, the air flow velocity in the air supply channel is reduced, thereby reducing the air flow resistance, effectively reducing the overall pressure drop, and at the same time effectively reducing the noise and increasing the air volume; and by respectively arranging the first heat exchange core 20 and the second heat exchange core 30 in the first air duct 12 and the second air duct 13, it can be ensured that when air flows through the two independent air ducts, it can respectively perform heat exchange with the two heat exchange cores. Compared with the existing air-conditioning box with a single air duct, the heat exchange area is increased, the heat exchange efficiency is also improved, and at the same time, more precise control of the air flow distribution in different areas of the vehicle can be achieved. Moreover, the air flow only passes through one core in each air duct, and the air flow resistance is small, which can effectively reduce the noise and increase the air volume.

[0061] As Figure 1 shown, in some alternative examples of the present utility model, the air inlet includes an external circulation air inlet and an internal circulation air inlet. An air inlet damper h is provided in the box body 10. The air inlet damper h is located between the external circulation air inlet and the internal circulation air inlet. The air inlet damper h is rotatably connected to the box body 10, and the intake mode of the internal and external circulations can be adjusted by the size of its rotation angle. For example, the air inlet damper h is movable between a first intake position and a second intake position. When the air inlet damper h is located at the first intake position, the external circulation air inlet is closed, and the box body 10 is in the state of internal circulation air intake; when the air inlet damper h is located at the second intake position, the internal circulation air inlet is closed, and the box body 10 is in the state of external circulation air intake.

[0062] According to an embodiment of the present utility model, the first heat exchange core 20 is adapted to heat and / or cool the air flow flowing through the first heat exchange core 20; and / or, the second heat exchange core 30 is adapted to heat and / or cool the air flow flowing through the second heat exchange core 30.

The entire space inside the box body 10 is fully utilized, and the heat exchange area is large, which can effectively improve the heating efficiency of the automotive air conditioning box 100.

[0065] Situation 2: Both the first heat exchange core 20 and the second heat exchange core 30 have a cooling function. Compared with the prior art, in the refrigeration condition of the automotive air conditioning box 100 in this embodiment, the first heat exchange core 20 and the second heat exchange core 30 can respectively cool the air flow flowing through them. The entire space inside the box body 10 is fully utilized, and the heat exchange area is large, which can effectively improve the refrigeration efficiency of the automotive air conditioning box 100.

[0066] Situation 3: Both the first heat exchange core 20 and the second heat exchange core 30 have a heating function and a cooling function, so that the first heat exchange core 20 and the second heat exchange core 30 can both heat the air flow flowing through them and cool the air flow flowing through them. Thus, while realizing the heating and cooling of the air flow, the use of components can be reduced, and the usage requirements of the automotive air conditioning box 100 can be met, and the heating efficiency and refrigeration efficiency of the automotive air conditioning box 100 can be effectively improved.

[0067] In some specific embodiments of the present utility model, the first heat exchange core 20 is provided with a first heat exchange flow channel, and the first heat exchange flow channel is adapted to circulate a heat exchange medium; and / or, the second heat exchange core 30 is provided with a second heat exchange flow channel, and the second heat exchange flow channel is adapted to circulate a heat exchange medium.

That is, the first heat exchange flow channel has a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet of the first heat exchange flow channel can be connected to the circulation loop of the heat exchange medium of the automotive air conditioning system. The temperature of the heat exchange medium can be adjusted through the automotive air conditioning system, so that the first heat exchange core 20 can be used to heat the air flow and also to cool the air flow.

[0069] Further, the second heat exchange core 30 is provided with a second heat exchange flow channel, and the second heat exchange flow channel is adapted to circulate a heat exchange medium (for example, the coolant of a vehicle).

The temperature of the heat exchange medium can be adjusted through the automotive air conditioning system, so that the second heat exchange core 30 can be used to heat the air flow and also to cool the air flow.

[0070] According to an embodiment of the present invention, the inner wall of the first air passage 12 is provided with a first installation groove adapted to install the first heat exchange core 20, and the inner wall of the second air passage 13 is provided with a second installation groove adapted to install the second heat exchange core 30.

The first installation groove plays a positioning role when installing the first heat exchange core 20, which is convenient for installation and can ensure the stability of the first heat exchange core 20 at the same time; the inner wall of the second air passage 13 in the height direction is provided with a second installation groove adapted to the end of the second heat exchange core 30. The second installation groove plays a positioning role when installing the second heat exchange core 30, which is convenient for installation and can ensure the stability of the second heat exchange core 30 at the same time.

[0072] In some alternative examples of the present invention, an air passage defining portion 11 is provided in the housing 10, and the air passage defining portion 11 and the inner wall surface of the housing 10 define the first air passage 12 and the second air passage 13.

[0073] That is to say, as Figure 1 shown, an air passage defining portion 11 is provided in the housing 10. The air passage defining portion 11 is formed as a plate-like structure. The width direction of the air passage defining portion 11 can be the same as the width direction of the vehicle. The first end of the air passage defining portion 11 is close to the air inlet, and the second end of the air passage defining portion 11 is close to the air outlet. The first air passage 12 and the second air passage 13 are defined by the air passage defining portion 11 and the inner wall surface of the housing 10, and the structure is simple.

[0074] In some specific embodiments of the present invention, a first water collecting groove 111 is provided on the side of the air passage defining portion 11 close to the first air passage 12, and the first water collecting groove 111 is located on the side of the first heat exchange core 20 close to the air outlet.

[0075] Specifically, as Figure 1As shown, on one side of the airway defining portion 11 close to the first airway 12 (i.e., the upper side of the airway defining portion 11), there is a first water collecting tank 111 extending along the length direction of the air inlet, and the first water collecting tank 111 is located on one side of the first heat exchange core 20 close to the air outlet, so that the condensed water generated by the cooling of the air flow passing through the first heat exchange core 20 can be collected, the condensed water can be prevented from being blown out from the air outlet along with the air flow, and the performance of the automotive air conditioning box 100 can be ensured.

[0076] According to an embodiment of the present invention, on the wall surface of the second airway 13 away from the airway defining portion 11, there is a second water collecting tank 14, and there is a diversion channel 15 connecting the first water collecting tank 111 and the second water collecting tank 14 to each other, and there is a water outlet on one side of the second water collecting tank 14.

[0077] That is to say, as Figure 1 and Figure 3 shown, on one side of the airway defining portion 11 close to the second airway 13 (i.e., the lower side of the airway defining portion 11), there is a second water collecting tank 14, the second water collecting tank 14 can be located directly below the first water collecting tank 111, there is a diversion channel 15 connecting the first water collecting tank 111 and the second water collecting tank 14 to each other, and a water outlet is arranged at a lower position of the second water collecting tank 14, so that the water in the first water collecting tank 111 can flow into the second water collecting tank 14 along the diversion channel 15 and flow out from the water outlet, and further, the water in the first water collecting tank 111 can be prevented from being blown out from the air outlet along with the air flow, and the performance of the automotive air conditioning box 100 can be ensured.

[0078] In some alternative examples of the present invention, there is a diversion groove connecting the first water collecting tank 111 and the second water collecting tank 14 to each other, and the inner wall surface of the diversion groove defines the diversion channel 15.

[0079] In other words, the diversion channel 15 between the first water collecting tank 111 and the second water collecting tank 14 can be defined by the inner wall surface of the diversion groove, that is, there is a diversion groove between the first water collecting tank 111 and the second water collecting tank 14, the first end of the diversion groove extends to the first water collecting tank 111 so that the first end of the diversion groove is communicated with the first water collecting tank 111, the second end of the diversion groove extends to the second water collecting tank 14 so that the first end of the diversion groove is communicated with the second water collecting tank 14, and the structure is simple and convenient for production and manufacturing.

[0080] In some specific embodiments of the present invention, the automotive air conditioning box 100 further includes: a diversion pipe, the diversion pipe is arranged between the first water collecting tank 111 and the second water collecting tank 14, the first end of the diversion pipe is communicated with the first water collecting tank 111, the second end of the diversion pipe is communicated with the second water collecting tank 14, and the inner wall surface of the diversion pipe defines the diversion channel 15.

[0081] Specifically, the diversion channel 15 between the first water collecting tank 111 and the second water collecting tank 14 can be defined by the inner wall surface of a diversion pipe. That is, a diversion pipe is provided between the first water collecting tank 111 and the second water collecting tank 14. The first end of the diversion pipe is communicated with the first water collecting tank 111, and the second end of the diversion pipe is communicated with the second water collecting tank 14. Compared with the above embodiments, there is no need to open a groove on the box body 10, which can ensure the structural strength of the box body 10 and has a good diversion effect.

[0082] According to an embodiment of the present invention, diversion channels 15 are provided at both ends of the first water collecting tank 111, and the middle of the first water collecting tank 111 is higher than both ends of the first water collecting tank 111.

[0083] That is to say, a diversion channel 15 is provided between the first end of the first water collecting tank 111 and the second water collecting tank 14, and a diversion channel 15 is also provided between the second end of the second water collecting tank 14 and the second water collecting tank 14, so that the water in the first water collecting tank 111 can be quickly discharged. Moreover, the middle position of the first water collecting tank 111 is higher than both ends of the first water collecting tank 111, which is beneficial to the flow of the first water collecting tank 111 to the diversion channel 15, can avoid the problem of condensate retention in the first water collecting tank 111, and can prevent the condensate from being blown out from the air outlet along with the air flow.

As Figures 4 to 6 shown, when the first air door 40 is in the open position, the first air door 40 avoids the first end of the second air duct 13, so that the air flow can enter the first air duct 12 and the second air duct 13 simultaneously to increase the ventilation area; as Figure 7 and Figure 8 shown, when the first air door 40 is in the closed position, the first air door 40 blocks the first end of the second air duct 13, so that the air flow will not enter from the first end of the second air duct 13, and multiple modes can be provided for users to choose from, which will be specifically described in the subsequent mode description.

[0086] In some specific embodiments of the present utility model, the second heat exchange core 30 is disposed at the second end of the second air passage 13.

A connection port 112 is provided at a portion of the air passage defining portion 11 close to the second heat exchange core 30. The connection port 112 penetrates the air passage defining portion 11 in the thickness direction thereof, so that the first air passage 12 is communicated with the second air passage 13. The first heat exchange core 20 is located on a side of the connection port 112 away from the second heat exchange core 30, so that the air flow can enter the second air passage 13 through the connection port 112 after passing through the first heat exchange core 20 and pass through the second heat exchange core 30.

[0088] As Figure 1 shown, a second air door 50 is installed at the position of the connection port 112 of the air supply passage, that is, the second air door 50 is rotatably connected to the box body 10, and the second air door 50 is rotatable between an open position and a closed position. When the second air door 50 is in the open position, the second air door 50 avoids the connection port 112, and the connection port 112 is opened, and the gas in the first air passage 12 can enter the second air passage 13 through the connection port 112; when the second air door 50 is in the closed position, the second air door 50 blocks the connection port 112, and the connection port 112 is closed, and the gas in the first air passage 12 cannot enter the second air passage 13 through the connection port 112.

[0089] Thus, by providing the second air door 50, the communication between the first air passage 12 and the second air passage 13 can be controlled, so that the air flow can pass through the first heat exchange core 20 and then pass through the second heat exchange core 30, which can meet different mode requirements of the automotive air conditioning box 100.

[0090] According to an embodiment of the present utility model, the automotive air conditioning box 100 further includes: a third air door 60, which is disposed at the second end of the first air passage 12 and is adapted to close and open the second end of the first air passage 12.

[0091] That is to say, as Figure 1As shown, a third air damper 60 is provided at the second end of the first air duct 12. The third air damper 60 is rotatably connected to the box body 10, and the second air damper 50 is rotatable between an open position and a closed position. When the third air damper 60 is in the open position, the second air damper 50 is displaced from the second end of the first air duct 12, and the second end of the first air duct 12 is opened, and the air flow in the first air duct 12 can flow out from the second end of the first air duct 12; when the third air damper 60 is in the closed position, the third air damper 60 blocks the second end of the first air duct 12, the second end of the first air duct 12 is closed, and the air flow in the first air duct 12 does not flow out from the second end of the first air duct 12. At this time, when the second air damper 50 is in the open position, the air flow in the first air duct 12 enters the second air duct 13 through the connection port 112 and flows out from the second end of the second air duct 13.

[0092] In some specific embodiments of the present invention, the first air duct 12 and the second air duct 13 communicate with the air outlet through the distribution cavity 16. The air outlet includes a defrosting air outlet a, a face-blowing air outlet b, and a foot-blowing air outlet c. Among them, the defrosting air outlet a and the face-blowing air outlet b are located at the second end of the first air duct 12, and the foot-blowing air outlet c is located at the second end of the second air duct 13. The automotive air-conditioning box 100 further includes: a fourth air damper 70, a fifth air damper 80, and a sixth air damper 90. The fourth air damper 70 is provided at the defrosting air outlet a, and the fourth air damper 70 is adapted to close and open the defrosting air outlet a. The fifth air damper 80 is provided at the face-blowing air outlet b, and the fifth air damper 80 is adapted to close and open the face-blowing air outlet b. The sixth air damper 90 is provided at the foot-blowing air outlet c, and the sixth air damper 90 is adapted to close and open the foot-blowing air outlet c.

[0093] In other words, as Figure 1 shown, the air outlet according to the embodiment of the present invention includes a defrosting air outlet a, a face-blowing air outlet b, and a foot-blowing air outlet c. Among them, the defrosting air outlet a and the face-blowing air outlet b are located at the second end of the first air duct 12. The defrosting air outlet a can be arranged upward, the face-blowing air outlet b can be arranged obliquely upward, the foot-blowing air outlet c can be arranged downward, and the foot-blowing air outlet c can be divided into a front foot-blowing sub-air outlet and a rear foot-blowing sub-air outlet for the use of front and rear row passengers.

[0094] [[ID=\\(11\\)]]As Figure 1As shown, a fourth air door 70 is provided in the defrost air outlet a. The fourth air door 70 is rotatably connected to the box body 10 and can rotate between an open position and a closed position. When the fourth air door 70 is in the open position, the fourth air door 70 avoids the defrost air outlet a, and the defrost air outlet a is opened, and air flow can blow out from the defrost air outlet a. A fifth air door 80 is provided in the face air outlet b. The fifth air door 80 is rotatably connected to the box body 10 and can rotate between an open position and a closed position. When the fifth air door 80 is in the open position, the fifth air door 80 avoids the face air outlet b, and the face air outlet b is opened, and air flow can blow out from the face air outlet b. A sixth air door 90 is provided in the foot air outlet c. The sixth air door 90 is rotatably connected to the box body 10 and can rotate between an open position and a closed position. When the sixth air door 90 is in the open position, the sixth air door 90 avoids the foot air outlet c, and the foot air outlet c is opened, and air flow can blow out from the foot air outlet c.

[0095] In some optional examples of the present utility model, the box body 10 mainly includes a main housing and an air inlet housing connected together. The air supply channel and the air outlet are provided in the main housing, the air inlet is provided in the air inlet housing, and a blower is further provided in the air inlet housing. The blower includes an impeller and a driving motor. The output end of the driving motor is fixedly connected to the impeller. The driving motor is fixedly installed in the air inlet housing, and the impeller is rotatably installed in the air inlet housing. Thus, the impeller can be driven to rotate by the driving motor, and air can be supplied to the air supply channel.

[0096] It should be noted that the air door in the present utility model can be driven by a motor-driven mode disk or a gear, and the transmission drive is realized through structures such as a lever, a driven gear or a rack.

[0097] Furthermore, the main housing includes a first outer shell, a second outer shell and a partition fixedly connected together. The partition is located between the first outer shell and the second outer shell. The internal spaces of the first outer shell and the second outer shell can be separated by the partition to form two air supply channels, and the air outlet is also divided into two parts, so as to facilitate separate control of the driver's and passenger's positions in the vehicle.

[0098] As Figure 4 shown, when the automotive air-conditioning box 100 according to the embodiment of the present utility model is in the full-cooling face-blowing mode, the first air door 40 is in the second position, the third air door 60 is in the open position, the fifth air door 80 is in the open position, and both the sixth air door 90 and the fourth air door 70 are in the closed position. Air is driven by the fan to enter the air-conditioning box body 10 from the air inlet, and the air flow is divided into upper and lower paths. As Figure 2As shown by the dashed arrows in the figure, the air flow in the first air duct 12 passes through the first heat exchange core 20 and the third air damper 60 and then enters the distribution cavity 16. The air flow in the second air duct 13 passes through the second heat exchange core 30 and then enters the distribution cavity 16. After the upper and lower air flows are aggregated into one path in the distribution cavity 16, they are blown out from the face blowing air outlet b. In this working mode, the heat exchange working mediums inside the first heat exchange core 20 and the second heat exchange core 30 are both low-temperature fluids. The upper and lower air flows decrease in temperature after passing through the heat exchange cores, realizing the working condition requirements of full cold face blowing.

[0099] As Figure 5 shown, when the vehicle air-conditioning box 100 according to the embodiment of the present invention is in the full heat foot blowing mode, similar to the full cold face blowing mode, the air is divided into two parallel paths along the Figure 3 path shown by the dashed arrows in the figure. The air flow in the first air duct 12 passes through the first heat exchange core 20 and the third air damper 60, and then the air flow in the second air duct 13 passes through the second heat exchange core 30 and enters the distribution cavity 16. After the upper and lower air flows are aggregated into one path in the distribution cavity 16, they are blown out from the foot blowing air outlet c. In this working mode, the sixth air damper 90 is in the open state, the fifth air damper 80 and the fourth air damper 70 are in the closed state, and the heat exchange working mediums inside the first heat exchange core 20 and the second heat exchange core 30 are both high-temperature fluids. The upper and lower air flows increase in temperature after passing through the heat exchange cores, realizing the working condition requirements of full heat foot blowing.

[0100] As Figure 6 shown, when the vehicle air-conditioning box 100 according to the embodiment of the present invention is in the full heat defrosting mode, except that the opening state of the air damper at the defrosting air outlet is different from that in the full heat foot blowing mode, the working states of the rest of the components are the same as those in the full heat foot blowing mode. The air flows through the box body 10 along the Figure 5 path of the dashed arrow in the figure. The fourth air damper 70 is in the open state, the fifth air damper 80 and the sixth air damper 90 are in the closed state, and the heat exchange working mediums inside the first heat exchange core 20 and the second heat exchange core 30 are both high-temperature fluids. The upper and lower air flows increase in temperature after passing through the heat exchange cores, realizing the working condition requirements of full heat defrosting.

[0101] As Figure 7 shown, when the vehicle air-conditioning box 100 according to the embodiment of the present invention is in the defogging mode, the first air damper 40 is in the closed state, the air flow flowing into the box body 10 is no longer divided into two paths, the third air damper 60 is in the closed state, and the second air damper 50 is in the open state. When the fourth air damper 70 is in the open state, the air entering the box body 10 is along Figure 6The path indicated by the dashed arrow in the figure first flows through the first heat exchange core 20 and the second heat exchange core 30, and then flows out from the defrost air outlet a through the distribution cavity 16. A low-temperature heat exchange medium is introduced into the first heat exchange core 20, and a high-temperature heat exchange medium is introduced into the second heat exchange core 30. In a scenario with a relatively high ambient relative humidity, after the air flow passes through the low-temperature first heat exchange core 20, water vapor is condensed and removed. Then, the air flow is heated by the second heat exchange core 30, and a high-temperature and dry air flow is discharged from the outlet, which can be used for working conditions such as front windshield defogging, meeting the requirements of defogging performance. Since the air volume requirement for the defogging working condition is small, therefore, this air path that first passes through the first heat exchange core 20 and then through the second heat exchange core 30 will not have a great impact on the performance.

[0102] As Figure 9 shown, when the vehicle air conditioner box 100 according to the embodiment of the present invention is in the face and foot blowing mode, the first air door 40, the fifth air door 80, the sixth air door 90, and the third air door 60 are all in the open state, and the fourth air door 70 and the second air door 50 are in the closed state. The air flows along Figure 9 the path indicated by the dashed arrow in the figure through the air conditioner box body 10, and the air flow is divided into upper and lower paths. In this working mode, a relatively high-temperature heat exchange medium is introduced into the first heat exchange core 20, and a higher-temperature heat exchange medium is introduced into the second heat exchange core 30. The temperature of the upper path air flow rises after passing through the first heat exchange core 20 and is blown out from the face blowing air outlet b, and the temperature of the lower path air flow rises after passing through the second heat exchange core 30 and is blown out from the foot blowing air outlet c. Relying on the design of the internal structure of the parallel air path of the present invention, by introducing heat exchange working media with different temperatures into the first heat exchange core 20 and the second heat exchange core 30, temperature stratification in the face and foot blowing mode can be achieved, that is, the relatively high-temperature air passes through the first air duct 12 and is blown out from the face outlet to avoid the face blowing air temperature being too high, and the higher-temperature hot air passes through the second air duct 13 and is blown out from the foot outlet to meet the requirement of foot warming. The output temperature adjustment of "cool head and warm feet" in the face and foot blowing mode can also be achieved by controlling the flow rates of the heat exchange media in the first heat exchange core 20 and the second heat exchange core 30, which can greatly improve the user experience. The temperature stratification of "cool head and warm feet" means that the air outlet temperature of the face blowing air outlet on the vehicle instrument panel is 5°C to 15°C lower than the air outlet temperature of the foot blowing air outlet.

[0103] As Figure 10 shown, when the vehicle air conditioner box 100 according to the embodiment of the present invention is in the foot and defrost mode, the first air door 40, the fourth air door 70, the sixth air door 90, and the third air door 60 are all in the open state, and the fifth air door 80 and the second air door 50 are in the closed state. The air flows along Figure 10The path indicated by the dotted arrow flows through the box body 10, and the air flow is divided into two paths, one above and one below. In this working mode, high-temperature heat exchange medium flows through both the first heat exchange core 20 and the second heat exchange core 30. After the air flow is heated by the first heat exchange core 20 and the second heat exchange core 30, it is blown out from the defrost outlet a and the foot-blowing outlet c, achieving the working goals of heating the front windshield and warming the feet. The design of the parallel air path enables the temperature of the two winds, defrosting and foot-blowing, to be adjusted separately. A typical adjustment is that the heat exchange medium in the first heat exchange core 20 will be about 5°C to 15°C lower than that in the second heat exchange core 30, so that the air temperature at the defrost outlet a is lower than the air temperature at the foot-blowing outlet c, to achieve head and foot temperature comfort stratification, and at the same time reduce the energy consumption of the air-conditioning box body 10 in the corresponding mode.

[0104] like Figure 11 As shown, when the automobile air conditioner 100 according to the embodiment of the present invention is in the face-blowing defrosting mode, the first damper 40, the fourth damper 70, the fifth damper 80, and the third damper 60 are all in the open state, and the sixth damper 90 and the second damper 50 are in the closed state. Figure 11 The path indicated by the dotted arrow flows through the air-conditioning box 10, and the air flow is divided into two paths, the upper and lower paths. In this working mode, high-temperature heat exchange medium is passed through the first heat exchange core 20 and the second heat exchange core 30. The upper air is heated by the first heat exchange core 20 and then discharged from the defrost outlet a. The lower air is discharged from the blowing surface outlet b after passing through the second heat exchange core 30, thereby achieving the working goal of heating the front windshield and the blowing surface. Due to the need for human comfort, the blowing surface air temperature is generally lower than the defrost air temperature. At this time, the temperature and flow rate of the heat exchange medium in the first heat exchange core 20 and the second heat exchange core 30 can be used to achieve zoned regulation of the outlet air temperature. Based on the same principle as described above, the design of the parallel air paths makes it possible for the temperature regulation of the defrost and blowing surfaces to not interfere with each other, which can improve human comfort when the air-conditioning box 10 is working.

[0105] like Figure 12 As shown, when the automobile air conditioner 100 according to the embodiment of the present invention is in the face-blowing and foot-blowing defrosting mode, the first damper 40, the fourth damper 70, the fifth damper 80, the sixth damper 90, and the third damper 60 are all in the open state, and the second damper 50 is in the closed state. Figure 12 The path indicated by the dashed arrows flows through the housing 10, with the airflow splitting into two paths, one above and one below. In this operating mode, high-temperature heat exchange medium flows through both the first heat exchange core 20 and the second heat exchange core 30. To ensure the aforementioned comfort requirements of a cool head and warm feet, the heat exchange medium temperature in the first heat exchange core 20 is typically lower than that in the second heat exchange core 30. After being heated by the first and second heat exchange cores 20 and 30, the air is then blown out through the defrost outlet a, the face outlet b, and the foot outlet c.

[0106] In some alternative examples of the present utility model, in the arrangement direction of the first air duct 12 and the second air duct 13, the first heat exchange core 20 and the second heat exchange core 30 partially overlap.

[0107] That is to say, as Figure 1 shown, in the arrangement direction of the first air duct 12 and the second air duct 13 (for example, the up-down direction), a part of the first heat exchange core 20 overlaps with a part of the second heat exchange core 30, which can make full use of the space inside the box body 10. Compared with the prior art, without increasing the outer boundary of the automotive air conditioning box 100, the heat exchange efficiency can still be effectively improved.

[0108] All in all, for the automotive air conditioning box 100 according to the embodiments of the present utility model, by providing a air supply channel including the first air duct 12 and the second air duct 13, the cross-sectional area of the air supply channel is effectively increased. Compared with the prior art air conditioning box with a single air duct, the air flow velocity in the air supply channel is reduced, thereby reducing the air flow resistance, effectively reducing the overall pressure drop, and at the same time being able to effectively reduce noise and increase the air volume; and by respectively arranging the first heat exchange core 20 and the second heat exchange core 30 in the first air duct 12 and the second air duct 13, when the air flows through the two independent air ducts, it can respectively exchange heat with the two heat exchange cores. Compared with the prior art air conditioning box with a single air duct, the heat exchange area is increased, the heat exchange efficiency is also improved, and at the same time, more precise control of the air flow distribution in different areas of the vehicle interior can be achieved. Moreover, the air flow only passes through one core in each air duct, and the air flow resistance is small, which can effectively reduce noise and increase the air volume.

[0109] The embodiments of the present utility model further provide an air conditioning system, including the automotive air conditioning box 100 described in any of the above embodiments. Since the automotive air conditioning box 100 according to the present utility model has the above technical effects, the air conditioning system according to the embodiments of the present utility model also has corresponding technical effects, which will not be elaborated in this embodiment.

[0110] In some examples of the present utility model, the air conditioning system further includes: a water pump 110, a three-way proportional valve 120, a first heat exchanger 130, and a second heat exchanger 140. The liquid inlet end of the water pump 110 is communicated with the liquid outlet ends of the first heat exchange core 20 and the second heat exchange core 30. The first end of the three-way proportional valve 120 is communicated with the liquid outlet end of the water pump 110. The liquid inlet end of the first heat exchanger 130 is communicated with the second end of the three-way proportional valve 120. The liquid outlet end of the first heat exchanger 130 is communicated with the liquid inlet end of the first heat exchange core 20. The liquid inlet end of the second heat exchanger 140 is communicated with the third end of the three-way proportional valve 120. The liquid outlet end of the second heat exchanger 140 is communicated with the liquid inlet end of the second heat exchange core 30. The water pump 110, the three-way proportional valve 120, the first heat exchanger 130, the second heat exchanger 140, the first heat exchange core 20, and the second heat exchange core 30 form a heat exchange flow path, and a heat exchange medium is filled in the heat exchange flow path.

[0111] That is to say, as Figure 13 shown, the air conditioning system can form a heat exchange flow path suitable for circulating a heat exchange medium (for example, coolant) through the water pump 110, the three-way proportional valve 120, the first heat exchanger 130, the second heat exchanger 140, the first heat exchange core 20, and the second heat exchange core 30. Specifically, the liquid outlet ends of the first heat exchange core 20 and the second heat exchange core 30 are combined into one path through a pipeline and then communicated with the liquid inlet end of the water pump 110, and the liquid outlet end of the water pump 110 is communicated with the first end of the three-way proportional valve 120.

[0112] The first heat exchanger 130 can be a plate heat exchanger. The first heat exchanger 130 has mutually staggered and independent first flow paths (for example, refrigerant flow paths) and second flow paths. Among them, the first flow path of the first heat exchanger 130 is used to be communicated with the circulation flow path of the refrigerant system. The second flow path of the first heat exchanger 130 has a liquid inlet end and a liquid outlet end. The liquid inlet end of the first heat exchanger 130 is communicated with the second end of the three-way proportional valve 120 through a pipeline, and the liquid outlet end of the first heat exchanger 130 is communicated with the liquid inlet end of the first heat exchange core 20.

[0113] The second heat exchanger 140 can be a plate heat exchanger. The second heat exchanger 140 has mutually staggered and independent first flow paths (for example, refrigerant flow paths) and second flow paths. Among them, the first flow path of the second heat exchanger 140 is used to be communicated with the circulation flow path of the refrigerant system. The second flow path of the second heat exchanger 140 has a liquid inlet end and a liquid outlet end. The liquid inlet end of the second heat exchanger 140 is communicated with the third end of the three-way proportional valve 120 through a pipeline, and the liquid outlet end of the second heat exchanger 140 is communicated with the liquid inlet end of the second heat exchange core 30.

[0114] In this example, the water pump 110 serves as a power source to drive the heat exchange medium to flow in the system. The three-way proportional valve 120 divides the heat exchange medium into two paths and can also adjust the proportion of the flow rates of the two paths. The first heat exchanger 130 and the second heat exchanger 140 can perform heat exchange on the heat exchange medium. Thus, by controlling the temperature of the refrigerant in the refrigerant system, the first heat exchanger 130 and the second heat exchanger 140 can function to cool or heat the heat exchange medium, and the cooling or heating power can also be adjusted by regulating the refrigerant system.

[0115] In some specific embodiments of the present utility model, the air-conditioning system further includes: a first heater 150, the liquid inlet end of the first heater 150 is connected to the liquid outlet end of the first heat exchanger 130, and the liquid outlet end of the first heater 150 is communicated with the liquid inlet end of the first heat exchange core 20; and / or, a second heater 160, the liquid inlet end of the second heater 160 is connected to the liquid outlet end of the second heat exchanger 140, and the liquid outlet end of the second heater 160 is communicated with the liquid inlet end of the second heat exchange core 30.

[0116] That is to say, as Figure 13 shown, in order to ensure the heating effect of the air-conditioning system, the air-conditioning system is provided with a first heater 150 (for example, a water PTC heater) between the first heat exchanger 130 and the first heat exchange core 20. The liquid inlet end of the first heater 150 is connected to the liquid outlet end of the first heat exchanger 130, and the liquid outlet end of the first heater 150 is communicated with the liquid inlet end of the first heat exchange core 20. Thus, through the first heater 150, the heat exchange medium flowing through can be heated between the first heat exchanger 130 and the first heat exchange core 20, the temperature of the heat exchange medium can be rapidly increased, which is beneficial to the rapid warming of the air-conditioning system and can ensure the heating effect of the air-conditioning system. <(

[0117] Further, the air-conditioning system is further provided with a second heater 160 (for example, a water PTC heater) between the second heat exchanger 140 and the second heat exchange core 30. The liquid inlet end of the second heater 160 is connected to the liquid outlet end of the second heat exchanger 140, and the liquid outlet end of the second heater 160 is communicated with the liquid inlet end of the second heat exchange core 30. Thus, through the second heater 160, the heat exchange medium flowing through can be heated between the second heat exchanger 140 and the second heat exchange core 30, the temperature of the heat exchange medium can be rapidly increased, which is beneficial to the rapid warming of the air-conditioning system and can further ensure the heating effect of the air-conditioning system.

[0118] The following further explains the corresponding relationships of the three situations mentioned in the foregoing embodiments in the system principle.

[0119] Case 1: When both the first heat exchange core 20 and the second heat exchange core 30 are in the heating function, taking the system path where the first heat exchange core 20 is located as an example, at this time, the first heater 150 works, and the first heat exchanger 130 does not work. The heat exchange medium is driven by the water pump 110 to the first heater 150 in the path where the first heat exchange core 20 is located and is heated to an appropriate temperature, and then flows into the first heat exchange core 20, so that the first heat exchange core 20 can heat the air flow passing through it in the air handling unit where it is located; the same applies to the second heat exchange core 30.

[0120] Case 2: When both the first heat exchange core 20 and the second heat exchange core 30 are in the cooling function, taking the system path where the first heat exchange core 20 is located as an example, at this time, the first heater 150 does not work, and the first heat exchanger 130 works. The heat exchange medium flowing through the first heat exchanger 130 is cooled to an appropriate temperature and then flows into the first heat exchange core 20, so that the first heat exchange core 20 can cool the air flow; the same applies to the second heat exchange core 30.

[0121] Case 3: When the first heat exchange core 20 is in the cooling function and the second heat exchange core 30 is in the heating function, in the system path where the first heat exchange core 20 is located, the first heater 150 does not work, and the first heat exchanger 130 works. The engine coolant cooled to an appropriate temperature flows into the first heat exchange core 20; in the system path where the second heat exchange core 30 is located, the second heater 160 works, and the second heat exchanger 140 does not work. The engine coolant heated to an appropriate temperature flows into the second heat exchange core 30 to achieve the corresponding functions.

[0122] The following further explains the temperature regulation:

[0123] As mentioned above, due to the combined action of the water pump 110 and the three-way proportional valve 120, the flow rate through the heat exchange core can be accurately controlled; while the first heat exchanger 130 and the second heat exchanger 140 play the role of cooling the heat exchange medium in the cooling system, and the power of the first heat exchanger 130 and the second heat exchanger 140 can be adjusted through the refrigerant system, that is to say, the heat exchange medium can be cooled to a specified temperature through the first heat exchanger 130 and the second heat exchanger 140; the first heater 150 and the second heater 160 are used to heat the heat exchange medium, and the power is controllable, that is to say, the heat exchange medium can be heated to a specified temperature through the first heater 150 and the second heater 160. Because the paths where the first heat exchange core 20 and the second heat exchange core 30 are located are both equipped with independent heaters and heat exchangers, that is to say, the flow rate and temperature of the heat exchange medium of the first heat exchanger 130 core and the second heat exchanger 140 core can be independently adjusted. Further, it means that the air flow temperature flowing through the two heat exchanger cores can be independently adjusted. Once, the high and low adjustment of the outlet air temperature can be easily and accurately achieved, and the different outlet air temperatures of different air outlets can also be easily and accurately achieved. A typical situation such as the comfort requirement of cool head and warm feet mentioned above can be well met.

[0124] An embodiment of the present utility model further provides a vehicle, including the air conditioning system described in any of the above embodiments. Since the automotive air conditioning box 100 according to the present utility model has the above technical effects, the vehicle according to the embodiment of the present utility model also has corresponding technical effects, which will not be elaborated in this embodiment.
