Description

Technical Field

[0001] The present application relates to the technical field of automobile air conditioning, and in particular to a noise-reducing built-in automobile air conditioning box assembly, a vehicle, and a control method. Background Art

[0002] With the improvement of people's living standards and the development of automobile technology, people's requirements for automobiles are no longer limited to ensuring safety and reliability, but also put forward higher requirements for the comfort of automobiles, especially high-end automobiles. Automobile air conditioners are mainly used to adjust the riding environment inside the car, and improve riding comfort by adjusting the air volume and fresh air temperature.

[0003] However, the comfort of a car also includes the control of noise inside the car. To control noise, the entire vehicle must have good sealing properties to isolate external noise. But when the air-conditioning system is turned on, whether it is internal circulation or external circulation, it needs to be connected to the interior of the car through the air outlet. The noise generated when the air conditioner is running will directly enter the car through the air outlet. Therefore, controlling the noise of the air conditioner becomes the key to solving the problem.

[0004] Automobile air conditioners consist of components such as evaporators and heater cores. The refrigerant exchanges heat with the air through the evaporator. The air after heat exchange enters the passenger compartment through the air duct to cool the passenger compartment. In order to ensure uniform heat exchange of the evaporator, from the perspective of heat exchange, it is hoped that the surface wind speed flowing through the evaporator is consistent.

[0005] Then, due to the limitations of the spatial structure of the car air conditioner, there is insufficient heat exchange outside the local area of ​​the evaporator, but the internal refrigerant is still flowing, causing the local temperature of the evaporator to be too low, which in turn causes local frost on the evaporator and makes heat exchange impossible, thereby affecting the cooling capacity of the car air conditioner and the cooling effect of the passenger compartment. If the frost on the surface of the evaporator worsens, it may also cause damage to the compressor. Summary of the invention

[0043] 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 ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The embodiments of the present application provide a noise-reducing embedded automobile air-conditioning box assembly, a vehicle, and a control method, which can solve the problem in the related art that, due to the limitations of the automobile air-conditioning space structure, there is insufficient heat exchange outside the local area of ​​the evaporator, thereby affecting the cooling effect of the passenger compartment.

[0045] See also Figure 1 and Figure 2 As shown, the first aspect of the embodiment of the present application provides a noise-reducing built-in automobile air-conditioning box assembly, comprising:

[0046] The evaporator bin 10 is provided with an evaporation core 11, which is arranged horizontally in the evaporator bin 10, with the lower part of the evaporation core 11 being the air inlet direction, and the upper part of the evaporation core 11 being the air outlet direction. The fresh air entering the evaporator bin 10 exchanges heat with the evaporation core 11 to form cold air. An air inlet 12 located upstream of the evaporation core 11 is provided on one side of the bottom of the evaporator bin 10, as well as a movable air guide assembly 13 that guides the fresh air entering the air inlet 12 into the evaporation core 11 at a set angle.

[0047] The blower compartment 20 is located at one side of the evaporator compartment 10. The blower compartment 20 is provided with a fresh air inlet and a fresh air outlet 23. The fresh air outlet 23 is connected to the air inlet 12 of the evaporator compartment 10 in an inclined downward direction. A plurality of fixed air guide blades 24 are provided in the fresh air outlet 23. The fixed air guide blades 24 are used to divide and guide the fresh air blown out from the blower compartment 20 into the air inlet 12, thereby avoiding eddy currents and turbulences generated by the blown fresh air at the connection between the fresh air outlet 23 and the air inlet 12 of the evaporator compartment 10.

[0048] The noise-reducing built-in automobile air-conditioning box assembly of the embodiment of the present application is provided with an air inlet 12 located upstream of the evaporator core 11 on one side of the bottom of the evaporator compartment 10, the blower compartment 20 is located on one side of the evaporator compartment 10, and the fresh air outlet 23 of the blower compartment 20 is connected to the air inlet 12 of the evaporator compartment 10 in an inclined downward direction, the blower compartment 20 and the evaporator compartment 10 are interconnected to form a side-blowing air intake air-conditioning shell structure.

[0049] The side-blowing air-intake air conditioner housing structure makes the flow direction of the fresh air entering the air inlet 12 from the fresh air outlet 23 be horizontal, while the air inlet direction of the evaporation core 11 is vertically upward, and the angle between the horizontal direction and the vertically upward direction is close to being perpendicular to each other. Therefore, it is difficult for the fresh air entering the evaporator compartment 10 to fully exchange heat with the evaporation core 11, but the refrigerant inside the evaporation core 11 is still flowing, resulting in the local temperature of the evaporation core 11 being too low, and then causing the evaporation core 11 to be partially frosted, unable to exchange heat, thereby affecting the cooling capacity of the automobile air conditioner, and then affecting the cooling effect of the passenger compartment.

[0050] In order to solve the problem that the fresh air entering the evaporator bin 10 is difficult to fully exchange heat with the evaporator core 11, the embodiment of the present application is provided with a movable air guide component 13 at the bottom of the evaporator bin 10 to guide the fresh air entering the air inlet 12 to the evaporator core 11 at a set angle. The movable air guide component 13 can make the flow direction of the fresh air as perpendicular to the evaporator core 11 as possible, so that the surface of the evaporator core 11 is heated more evenly, the heat exchange effect is more sufficient, and the temperature distribution on the surface of the evaporator core 11 is more uniform, so that the outlet temperature of the air blown to the air outlet of the cab is more consistent and balanced.

[0051] In some alternative embodiments: See Figure 1 and Figure 2As shown, the embodiment of the present application provides a noise-reducing built-in automobile air-conditioning box assembly, in which an expansion valve 14 and a refrigerant pipeline 15 for connecting an evaporating core 11 are provided in an evaporator bin 10 of the noise-reducing built-in automobile air-conditioning box assembly, and the expansion valve 14 and the refrigerant pipeline 15 are both located in the upstream direction of the evaporating core 11 and away from the air inlet 12. The expansion valve 14 and the refrigerant pipeline 15 are directly opposite to the air inlet 12 in the evaporator bin 10, and the fresh air entering the evaporator bin 10 from the air inlet 12 intersects with the expansion valve 14 and the refrigerant pipeline 15, so as to generate noise and turbulence.

[0052] In order to solve the problem of noise and turbulence caused by the intersection of the fresh air entering the evaporator bin 10 from the air inlet 12 with the expansion valve 14 and the refrigerant pipeline 15, the embodiment of the present application is provided with an air guide plate 16 in the evaporator bin 10, near the upstream of the evaporation core 11 and bent from the air inlet 12 toward the expansion valve 14 and the refrigerant pipeline 15. The air guide plate 16 separates the evaporation core 11 from the expansion valve 14 and the refrigerant pipeline 15. In addition, the distance between the air guide plate 16 and the evaporation core 11 gradually decreases in the direction away from the air inlet 12, and the distance between the air guide plate 16 and the air inlet 12 is greater than the distance between the movable air guide assembly 13 and the air inlet 12.

[0053] In the embodiment of the present application, an air guide plate 16 is formed in the evaporator bin 10, near the upstream of the evaporation core 11 and bent from the air inlet 12 toward the expansion valve 14 and the refrigerant pipeline 15. A cavity for embedding the expansion valve 14 and the refrigerant pipeline 15 is formed between the air guide plate 16 and the evaporator bin 10. The expansion valve 14 and the refrigerant pipeline 15 avoid noise and turbulence with the fresh air entering from the air inlet 12 in the cavity, and reduce the resistance of the fresh air to the evaporation core 11, so that when the fresh air flows to the air guide plate 16, it flows directly and parallel to the evaporation core 11 as much as possible to avoid the formation of a wind vortex.

[0054] In some alternative embodiments: See Figure 1 and Figure 2 As shown, the embodiment of the present application provides a noise-reducing built-in automobile air-conditioning box assembly, in which a blower compartment 20 is provided with a blower 25 located between a fresh air inlet and a fresh air outlet 23. The plurality of fixed air guide blades 24 include a straight air guide blade 26 and an arc-shaped air guide blade 27. The straight air guide blade 26 is close to the blower 25 and is perpendicular to the rotating shaft of the blower 25, and the arc-shaped air guide blade 27 is close to the fresh air outlet 23 and is bent toward the air inlet 12.

[0055] In the embodiment of the present application, since the blower compartment 20 is located on one side of the evaporator compartment 10, and the fresh air outlet 23 of the blower compartment 20 is connected to the air inlet 12 of the evaporator compartment 10 in an inclined downward direction, the blower compartment 20 and the evaporator compartment 10 are connected to each other to form a side-blowing air-inlet air-conditioning shell structure, and the connection between the fresh air outlet 23 and the air inlet 12 is a curved section for changing the flow direction of the fresh air. The straight air guide blades 26 and the arc-shaped air guide blades 27 are arranged in this curved section to guide and break up the turbulent fresh air and change the flow direction, so that it is evenly blown to the surface of the evaporation core 11, thereby ensuring uniform air intake of the evaporation core 11.

[0056] In some alternative embodiments: See Figures 1 to 5 As shown, the embodiment of the present application provides a noise-reducing built-in automobile air-conditioning box assembly, and the bottom of the evaporator bin 10 of the noise-reducing built-in automobile air-conditioning box assembly is provided with a mounting hole for mounting a movable air-guiding assembly 13. The movable air-guiding assembly 13 includes a bottom shell 131 with an open top and closed around, and the bottom shell 131 is detachably connected to the bottom of the evaporator bin 10. A plurality of rows of air-guiding blades arranged in sequence and rotatably connected are provided inside the bottom shell 131, and a driving mechanism for driving the plurality of rows of air-guiding blades to rotate is provided outside the bottom shell 131, and the plurality of rows of air-guiding blades gradually move away from the air inlet 12 in the horizontal direction.

[0057] Specifically, the wind guide blade group includes a wind guide blade fixing shaft 132 rotatably connected to the bottom shell 131, and a plurality of wind guide blades 133 fixed to the wind guide blade fixing shaft 132, and the plurality of wind guide blades 133 are arranged at intervals on the wind guide blade fixing shaft 132. The projections of the wind guide blades 133 of two adjacent rows of the multi-row wind guide blade group in the wind inlet direction do not overlap each other, and the driving mechanism includes a stepping motor 134 connected to each wind guide blade fixing shaft 132 respectively.

[0058] The movable air guide assembly 13 of the embodiment of the present application is provided with a plurality of rows of air guide blades arranged in sequence in a rotationally connected manner in the bottom shell 131. The air guide blade group is rotationally connected to the bottom shell 131 through an air guide blade fixing shaft 132. The air guide blade fixing shaft 132 is rotated on the bottom shell 131 to adjust the angle of the air guide blade 133 located on the air guide blade fixing shaft 132. The fresh air entering the evaporator bin 10 is guided by adjusting the air guide angle of the air guide blade 133, so that the fresh air is blown vertically and evenly to the surface of the evaporation core 11, so that the heat exchange on the surface of the evaporation core 11 is more sufficient, uniform and thorough.

[0059] The projections of the air guide blades 133 of two adjacent rows of the air guide blade groups in the embodiment of the present application along the air inlet direction do not overlap each other, so that the air guide blades 133 located in the front will not block and affect the continuous flow of fresh air to the air guide blades 133 located in the rear, and the air guide blades 133 located in the rear can also continue to guide the fresh air. The driving mechanism includes a stepper motor 134 connected to each air guide blade fixing shaft 132. The air guide blade fixing shafts 132 of the multi-row air guide blade group are respectively connected to the stepper motor 134, and the rotation angle of the air guide blades of each row of the air guide blade group can be flexibly controlled by their respective stepper motors 134.

[0060] Noise reduction and sound silencing cotton 135 is provided in the bottom shell 131, and the noise reduction and sound silencing cotton 135 is used to reduce the noise generated by the fresh air entering the bottom shell 131. The top of the evaporator compartment 10 is provided with a main passenger air outlet and a co-pilot air outlet located in the downstream direction of the evaporation core 11, and the fresh air inlet includes an internal circulation fresh air inlet 21 and an external circulation fresh air inlet 22. A switching valve plate is provided between the internal circulation fresh air inlet 21 and the external circulation fresh air inlet 22.

[0061] The embodiment of the present application can adjust the angle of the air guide blade 133 according to user needs, and then adjust the amount of cold air entering the main driver's seat and the co-driver's seat after entering the evaporation core 11. When there are passengers on both the main driver's seat and the co-driver's seat, the angle of the air guide blade 133 guides the fresh air to balance the air volume of the main driver's seat and the co-driver's seat. When there is only an occupant on the main driver's seat, the angle of the air guide blade 133 guides the fresh air to make the air volume of the main driver's seat outlet greater than the air volume of the co-driver's seat outlet, so that more cold air blows to the passenger on the main driver's seat side.

[0062] In addition, the embodiment of the application can adjust the angle of the air guide blade 133 by the size of the wind speed gear of the fresh air, and then adjust the angle of entry into the evaporator core 11. For example, when the wind speed gear is adjusted to the minimum, the air guide blade 133 increases the diversion angle to divert the fresh air. When the wind speed gear is adjusted to the maximum, the air guide blade 133 reduces the diversion angle to divert the fresh air. This can make the flow direction of the fresh air as perpendicular to the evaporator core 11 as possible, so that the surface of the evaporator core 11 is heated more evenly and the heat exchange effect is more sufficient.

[0063] See also Figure 6 As shown, the second aspect of the embodiment of the present application provides a vehicle, including: the noise-reducing embedded automobile air-conditioning box assembly described in any of the above embodiments; and a driver's seat and a passenger seat, the driver's seat is provided with a first seat sensor 31, and the passenger seat is provided with a second seat sensor 32; a vehicle controller 33, the first seat sensor 31, the second seat sensor 32 and the stepper motor 134 of the movable air guide assembly 13 are all connected to the vehicle controller 33.

[0064] When the first seat sensor 31 and the second seat sensor 32 detect that there are passengers on both the driver's seat and the passenger's seat, the vehicle controller 33 controls the stepper motor 134 to make the angle of the air guide blade 133 guide the fresh air so that the air volume of the driver's air outlet and the passenger's air outlet is balanced. When the first seat sensor 31 and the second seat sensor 32 detect that there is only an occupant on the driver's seat and the passenger's seat, the vehicle controller 33 controls the stepper motor 134 to make the angle of the air guide blade 133 guide the fresh air so that the air volume of the driver's air outlet is greater than the air volume of the passenger's air outlet, so that more cold air is blown to the occupant on the driver's seat side.

[0065] See also Figures 1 to 6 As shown, the third aspect of the embodiment of the present application provides a control method for a noise-reducing built-in automobile air-conditioning box assembly, the control method uses the vehicle described in the above embodiment, and includes the following steps:

[0066] Step 101 , after the blower 25 is started, the blower 25 blows the air from the fresh air inlet into the fresh air outlet 23 and then into the air inlet 12 of the evaporator bin 10 .

[0067] Step 102 , when there are occupants in both the driver's seat and the passenger seat, the first seat sensor 31 and the second seat sensor 32 send a first signal to the vehicle controller 33 .

[0068] Step 103 , after receiving the first signal, the vehicle controller 33 controls the stepper motor 134 of the movable air guide assembly 13 to rotate the air guide blades 133 to a set angle, so that the fresh air entering the air inlet 12 is vertically introduced into the evaporation core 11 .

[0069] Step 104 , when there is an occupant in the driver's seat and no occupant in the passenger seat, the first seat sensor 31 and the second seat sensor 32 send a second signal to the vehicle controller 33 .

[0070] Step 105, after receiving the second signal, the vehicle controller 33 controls the stepper motor 134 of the movable air guide assembly 13 to rotate the air guide blade 133 to a set angle, so that the fresh air entering the air inlet 12 is introduced into the evaporation core 11 and then most of it is discharged from the main driving air outlet.
