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

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

According to a first aspect of the present utility model, there is provided an air conditioning apparatus for a vehicle, comprising: the box body, the first air door 2, the first heat exchanger, the second air door 4, the second heat exchanger, the third air door 6 and the third heat exchanger; an air duct 1 is formed in the box body, and the first air door 2, the first heat exchanger, the second air door 4, the second heat exchanger, the third air door 6 and the third heat exchanger are sequentially arranged in the air duct 1; the first air door 2, the second air door 4 and the third air door 6 are respectively used for guiding the air flow direction in the air duct 1.

As shown in fig. 1 to 5, a first air door 2, a first heat exchanger, a second air door 4, a second heat exchanger, a third air door 6 and a third heat exchanger are sequentially arranged in a box body of the air conditioner provided by the utility model, namely, the first air door 2 is correspondingly arranged in front of the first heat exchanger, the second air door 4 is correspondingly arranged in front of the second heat exchanger, and the third air door 6 is arranged in front of the third heat exchanger, so that the three heat exchangers can correspondingly open and close through each air door under different working modes, and air in an air duct 1 can flow according to a preset path.

The types and specific setting modes of the first heat exchanger, the second heat exchanger and the third heat exchanger can be set according to actual demands and structures in the air duct 1, and the forms and setting modes of the air doors are set according to the types, setting positions and setting modes of the corresponding heat exchangers, so that the utility model is not limited to the types, the setting positions and the setting modes.

In the air conditioner, the number of the heat exchangers in the box body is increased by arranging the first heat exchanger, the second heat exchanger and the third heat exchanger, so that the heat exchange efficiency of the air conditioner is higher, and the temperature rise of air temperature is faster. Further, by arranging the air door at the front end of each heat exchanger, in practical application, when a certain heat exchanger works, the air door can be in an open state, and air in the air duct 1 is allowed to flow through the heat exchanger, so that a heat exchange function is realized. When a certain heat exchanger does not work, the air door can be in a closed state to shield the heat exchanger, so that air in the guide air duct 1 flows through the periphery of the corresponding heat exchanger, wind resistance to the air in the air duct 1 is avoided, the wind temperature is influenced, the heat exchange performance of each heat exchanger is improved, and the energy consumption is reduced.

It should be noted that, in this embodiment, the opening and closing of each air door may be intelligently controlled according to the working state of each heat exchanger, and the specific control manner may be implemented by a mechanical manner or an electrical control manner, which is not limited in this utility model.

Alternatively, referring to fig. 1 to 4, the first, second and third heat exchangers are an evaporator 3, a warm air core 5 and a condenser 7, respectively.

Specifically, in this embodiment, the three heat exchangers may be respectively an evaporator 3, a warm air core 5 and a condenser 7, that is, the air conditioning apparatus is a direct heat pump air conditioner, and compared with an indirect heat pump air conditioner, the condenser 7 is disposed in the box body, so that the heat exchange efficiency is higher, and the temperature of the air increases faster. In practical application, the arrangement sequence of the evaporator 3, the warm air core 5 and the condenser 7 in the air duct 1 can be arranged according to practical requirements, and the utility model is not limited to this.

Alternatively, referring to fig. 1 to 4, the first heat exchanger and the second heat exchanger are an evaporator 3 and a warm air core 5, respectively; the first air door 2 and the second air door 4 are interlocked with each other, so that the second air door 4 can allow air to flow through the warm air core 5 when the first air door 2 shields the evaporator 3; alternatively, the second damper 4 may block the warm air core 5 when the first damper 2 allows air to flow from the evaporator 3.

Specifically, in the present embodiment, the first air door 2 at the front end of the evaporator 3 and the second air door 4 at the front end of the warm air core 5 are set to be in a linked control mode, that is, the opening and closing of the first air door 2 and the second air door 4 are linked with each other, and this setting mode not only can reduce the resistance of the air duct 1, but also can simplify the control of the air doors in front of the plurality of heat exchangers in the box, and reduce the complexity of control instructions.

In practical application, the low-temperature condensed liquid passes through the evaporator 3 to exchange heat with the outside air, so that gasification absorbs heat and the refrigerating effect is achieved. And the air which can be heated quickly by the warm air core body 5 is a heating device. The different roles of the evaporator 3 and the warm air core 5 are such that they are not generally used at the same time. I.e. the air conditioning unit is typically in a single evaporator 3 mode (i.e. only the evaporator 3 is in operation) or in a single warm air core 5 mode (i.e. only the warm air core 5 is in operation), in which case the linkage of the first damper 2 and the second damper 4 makes the control of the whole air conditioning unit simpler.

As shown in fig. 1 to 4, schematic diagrams of internal structures of a box body of an air conditioner in different modes are provided. Wherein, evaporator 3, warm braw core 5 and condenser 7 set gradually from left to right. The evaporator 3 is provided with a first air door 2 in front, the first air door 2 has an a1 position and an a2 position, the air flow through the evaporator 3 is blocked when the first air door 2 is in the a1 position, and the air flows through the evaporator 3 when the first air door 2 is in the a2 position; a second air door 4 is arranged in front of the warm air core 5, and blocks air from flowing through the warm air core 5 when the warm air core 5 is in the b1 position, and air flows through the warm air core 5 when the warm air core 5 is in the b2 position; a third damper 6 is arranged in front of the condenser 7, and the third damper 6 blocks the flow of air through the condenser 7 when in the c1 position and blocks the flow of air through the condenser 7 when in the b2 position.

In the above-described structure, the control principle of the linkage of the first damper 2 and the second damper 4 may refer to fig. 6, and when the first damper 2 is located at a1, the second damper 4 is located at b2; conversely, when the first damper 2 is located at a2, the second damper 4 is located at b1, and the third damper 6 is independently controllable.

Optionally, the third heat exchanger is a condenser 7, and the third damper 6 can block the condenser 7 or can allow air to flow through the condenser 7 in a case that the first damper 2 blocks the evaporator 3 or the second damper 4 blocks the warm air core 5.

In the present embodiment, the third damper 6 may be individually controlled according to the heating capacity of the air conditioner (heat pump). Specifically, as shown in fig. 1, the single evaporator 3 mode (i.e. the air conditioner is in a cooling mode), at this time, the first damper 2 is moved from the a1 position to the a2 position, the second damper 4 is linked to the b1 position, and the third damper 6 is moved to the c1 position, at which time the wind flows through only the evaporator 3. Since wind flows through only one layer of heat exchangers, the wind resistance of the wind channel 1 is low, and the control logic thereof is referred to fig. 6.

As shown in fig. 2, in the single warm air core 5 mode (i.e., the air conditioner is in the heating mode), the first damper 2 is operated to a1, and the second damper 4 is linked to b 2. At this time, when the heating capacity of the heat pump is insufficient (such as the environment temperature is extremely low), the water PTC heats the hot water of the warm air loop to heat; or for the hybrid motor vehicle, when the water temperature of the engine is higher, the hot water of the engine can be used for heating the warm air loop for heating. Therefore, the third damper 6 is moved to the position c1 at this time, and the wind flows only through the warm air core 5.

As shown in fig. 3, in the mode of adding the condenser 7 to the warm air core 5, that is, when the heating capacity of the heat pump is sufficient or the temperature of the engine water is low, the third air door 6 is moved to the position c2 at this time, and the air flows through the warm air core 5 and then passes through the condenser 7.

As shown in fig. 4, in the mode of adding the condenser 7 to the evaporator 3, that is, when the air conditioner sends an air conditioner dehumidifying command, the first air door 2 moves to a2, the second air door 4 moves to b1, the third air door 6 moves to c2, and the air flows through the evaporator 3 and then passes through the condenser 7.

As can be seen from the above embodiments, in various working modes of the air conditioning apparatus provided by the present utility model, through the linkage of the first air door 2 and the second air door 4 and the independent control mode of the third air door 6, the resistance of the air flow (air) in the air duct 1 can be greatly reduced, the heat exchange efficiency is improved, and the energy consumption is reduced.

Optionally, the vehicle air conditioner further includes a linkage mechanism connected to the first damper 2 and the second damper 4, respectively, to control the positions or open/closed states of the first damper 2 and the second damper 4.

Specifically, in this embodiment, the linkage of the first air door 2 and the second air door 4 is implemented by a linkage mechanism, and the linkage mechanism is configured to make the linkage control of the first air door 2 and the second air door 4 more convenient and reliable, and the specific form thereof can be adaptively designed according to the specific structure of the air door, so that the existing linkage mechanism in the prior art can be applied, which is not limited in the present utility model.

Optionally, the first damper 2, the second damper 4 and the third damper 6 have a first position and a second position, respectively; in the first position, the first air door 2, the second air door 4 and the third air door 6 can respectively shield the corresponding heat exchanger; in the second position, the first damper 2, the second damper 4 and the third damper 6 are each capable of allowing air to flow through the corresponding heat exchanger.

Specifically, the first air door 2, the second air door 4 and the third air door 6 can be opened and closed, and in the opened state, wind can flow through the corresponding heat exchanger, so that the corresponding heat exchanger can be shielded when the heat exchange function is in the closed state, and wind current is prevented from flowing through the corresponding heat exchanger, so that wind resistance is reduced.

The opening and closing of the first, second and third dampers 2, 4, 6 may be achieved by the positional movement of the respective dampers, i.e. as shown in fig. 1 to 4, two positions are provided for each damper, e.g. the first damper 2 has a first position a1 and a second position a2, whereas the second damper 4 has a first position b1 and a second position b2, and the third damper 6 has a first position c1 and a second position c2, the opening and closing of the dampers being controlled by only controlling the movement of the respective dampers between the first and second positions.

In addition, the opening and closing of each damper may be achieved by a valve-like structure, and specifically may be selected according to the size and dimensions of the air duct 1 and the arrangement of the heat exchanger.

Alternatively, as shown in fig. 5, the width dimensions of the first damper 2, the second damper 4, and the third damper 6 in the direction from the edge position to the center position of the duct 1 are gradually reduced, the width dimensions being the cross-sectional dimensions of the windward sides of the respective dampers.

Specifically, the width dimension of each air door in the direction from the edge position to the center position is gradually reduced, so that in practical application, when the air door is opened or closed, namely, the air door is positioned at the first position or the second position, the width of the air door at a position close to the position where the wind flows through is smaller, the wind resistance of the air door to the air in the air duct 1 is reduced, and the heat exchange efficiency is further improved.

Optionally, the vehicle air conditioning device further comprises a control module, and the control module is connected with the linkage mechanism to control the first air door 2 and the second air door 4 through the linkage mechanism.

Specifically, in this embodiment, the control module is connected with the linkage mechanism, so that, in various working modes of the air conditioner, the control module can control the actions of the linkage mechanism, so as to control the states of the first air door 2 and the second air door 4, thereby improving the control intellectualization of the air conditioner.

Alternatively, as shown in fig. 1 to 4, the first heat exchanger, the second heat exchanger and the third heat exchanger are sequentially arranged in parallel and are respectively perpendicular to the air duct 1.

Specifically, in this embodiment, each heat exchanger is sequentially arranged in parallel in the air duct 1 and is perpendicular to the air duct 1, so that air can flow in the air duct 1 regularly, and wind resistance is further reduced. The heat exchangers are perpendicular to the air duct 1, namely working surfaces of the heat exchangers are arranged to be windward surfaces, so that windward areas can be enlarged, and heat exchange efficiency is improved.

According to a second aspect of the present utility model, there is provided a vehicle comprising the air conditioning apparatus for a vehicle according to the first aspect.

Specifically, in this embodiment, the vehicle provided includes the air conditioning device provided in the first aspect of the present utility model, and since the air conditioning device provided in the first aspect of the present utility model has the advantages of high heat exchange efficiency and low energy consumption, when the air conditioning device is applied to the vehicle, the temperature in the vehicle can be quickly adjusted, the comfort of the vehicle is improved, and the temperature control cost is reduced.

The foregoing embodiments mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in consideration of brevity of line text, no further description is given here.
