Description

Technical Field

[0001] This invention belongs to the field of automotive air conditioning technology. Specifically, this invention relates to a flow guiding method for a dual-layer flow split-type distributor. Background Technology

[0002] Currently, all water-heated air conditioners have the entire unit located inside the passenger compartment. In heating mode, the coolant is heated after flowing through the engine, PTC heater, or heat pump. A portion of the hot water (heated coolant) enters the heating core in the air conditioning unit. The blower forces the cold air to exchange heat with the heating core, and the heated air enters the passenger compartment through the air duct for heating. In cooling mode, the airflow temperature decreases after passing through the evaporator, and after being regulated by the damper, it no longer passes through the heating core and directly enters the passenger compartment for cooling.

[0003] Since the entire air conditioner is located in the driver's cabin, it occupies a large amount of interior space. When producing different vehicle models, the position and design of the entire air conditioner need to be changed according to the different vehicle models to adapt to them. In addition, noisy components such as blowers located in the vehicle interior will generate a lot of noise, affecting the driver's driving experience. Summary of the Invention

[0036] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0037] Please see Figure 1-10 A method for guiding airflow in a dual-layer flow split-type distributor is provided. The dual-layer flow split-type distributor includes a distributor box 1, which is divided into a main box 2 and a side box 3 located on the side of the main box 2. The main box 2 and the side box 3 are provided with an air guiding structure 4 for guiding the airflow direction and a heating structure 5 for heating the airflow. The heating structure 5 is provided with horizontal ribs 6 at both ends. The distributor box 1 is provided with an air inlet 7 and an air outlet 8.

[0038] Airflow is blown into the distributor box 1 through the air inlet 7. The airflow enters the main box 2 and the side box 3 respectively, and the airflow direction is guided by the air guide structure 4 in the distributor box 1. The cold airflow passes directly through the distributor box 1 and is discharged from the air outlet 8. When heating is needed, the airflow passes through the heating structure 5 separated by the horizontal rib 6 and is heated, and is discharged from the air outlet 8. The horizontal rib 6 can prevent the cold air from being heated. In this way, the heating and distribution of airflow can be completed by using the distributor box 1 as a single device, which has a wide range of applications.

[0039] The air outlet 8 includes a lower air outlet 81 located at the bottom of the main housing 2, a rear air outlet 82 located on the side of the main housing 2, left and right air outlets 83 located on the side of the side housing 3, an upper air outlet 85 located on the top of the distributor housing 1, and a defrost air outlet 84.

[0040] By using air outlets 8 at different locations and with different airflow directions, the heating or cooling air can be directed to different locations and directions, achieving different effects. This allows the airflow guidance function of the air conditioner to be completed using the distributor box 1.

[0041] The air guiding structure 4 includes a diverter plate 41, which is installed inside the distributor box 1. A first damper 42 is provided on one side of the diverter plate 41, a second damper 43 is provided on the other side of the diverter plate 41, a third damper 44 is provided between the horizontal rib 6 and the inner wall of the distributor box 1, a fourth damper 45 is provided at the upper air outlet 85, and a fifth damper 46 is provided at the defrost air outlet 84.

[0042] By using the first damper 42 and the second damper 43 in conjunction with the diverter plate 41, and by utilizing the horizontal ribs 6 at both ends of the heating structure 5, the heating structure 5 is sealed off, preventing the gas entering the distributor box 1 from the air inlet from passing through the heating structure 5 and being heated. At the same time, as the second damper 43 rotates upward and controls the third damper 44, cold air can be blown into the distributor box 1. When heating is needed, the third damper 44 is closed and the second damper 43 is rotated downward, so that the airflow injected into the distributor box 1 from the air inlet 7 will pass through the heating structure 5 and be heated into warm air. The fourth damper 45 and the fifth damper 46 control the opening and closing of the upper air outlet 85 and the defrost air outlet 84, respectively.

[0045] S2: The second air door 43 rotates downward, the first air door 42 opens, the third air door 44 closes, the airflow enters the main box 2 through the air inlet 7, the airflow passes through the heating structure 5 and becomes warm air, the lower air door 47 opens, and the warm air is sprayed out from the lower air outlet 81, thus completing the effect of spraying warm air from the lower air outlet 81 to provide foot heating.

[0046] S3: The second air door 43 rotates downward, the first air door 42 opens, the third air door 44 closes, the airflow enters the main box 2 through the air inlet 7, the airflow passes through the heating structure 5 and becomes warm air, the rear air door 48 opens, and the warm air is sprayed out from the rear air outlet 82. After the rear air outlet 82 sprays out warm air to provide leg heating effect.

[0050] S7: The second air door 43 rotates upward, the first air door 42 closes, the lower air door 47 opens, the airflow enters the main housing 2 from the air inlet 7 and is ejected from the lower air outlet 81, thus completing the purpose of cooling the feet by ejecting cold air from the lower air outlet 81.

[0051] S8: The second air door 43 rotates upward, the first air door 42 closes, and the rear air door 48 opens. Airflow enters the main housing 2 from the air inlet 7 and is ejected from the rear air outlet 82, thus completing the purpose of cooling the legs by ejecting cold air from the rear air outlet 82.

[0052] S9: The second air door 43 rotates upward, the first air door 42 closes, the fifth air door 46 and the third air door 44 open, the airflow enters the distributor box 1 from the air inlet 7 and is ejected from the defrost air outlet 84, thus completing the purpose of defogging by ejecting cold air from the defrost air outlet 84.

[0053] S10: The second damper 43 rotates upward, the first damper 42 closes, and the fourth sealing door and the third damper 44 open. The airflow enters the distributor box 1 from the air inlet 7 and is ejected from the upper air outlet 85, thus completing the purpose of cooling by ejecting cold air from the upper air outlet 85.

[0054] The horizontal ribs 6 are located at both ends of the heating structure 5. The first damper 42, the diverter plate 41, and the second damper 43 are located between the horizontal ribs 6 on both sides. The horizontal ribs 6, together with the first damper 42, the diverter plate 41, and the second damper 43, enclose the heating structure 5. When the heating airflow is not needed, the heating structure 5 is closed to reduce the occurrence of heat exchange.

[0055] The third damper 44 is located between the horizontal rib 6 and the inner wall of the distributor box 1; the direction of airflow is controlled by opening and closing the gap between the horizontal rib 6 and the distributor box 1 through the third damper 44.

[0056] When the second damper 43 rotates to one side, both sides of the second damper 43 are in contact with the diversion plate 41 and the horizontal rib 6. When the second damper 43 rotates to the other side, both sides of the second damper 43 are in contact with the diversion plate 41 and the distributor box 1. The second damper 43 is used to control the opening and closing of the gaps on the upper and lower sides of the horizontal rib 6, thereby reducing structural redundancy.

[0057] The heating structure 5 is a warm air core or a heat pump core. The heating structure 5 is located at one end of the horizontal rib 6, and a connecting plate 10 is provided on one side of the heating structure 5. The warm air core or heat pump core is used to heat the airflow passing through the heating structure 5.

[0058] A downwind door 47 is provided at the downwind vent 81, a rear air vent 48 is provided at the rear air vent 82, and guide plates 49 are provided at the left and right air vents 83.

[0059] A partition 9 is provided between the main housing 2 and the side housing 3 to separate the main housing 2 and the side housing 3, and to control different air outlets 8 respectively.

[0060] The technical advantages of this invention are as follows: By using the distributor box 1, the effect of cold or warm air being sprayed from any air outlet can be controlled. Since the distributor box 1 is separate from the original air conditioner, its overall size is small and it can be used independently. Moreover, it only needs to connect the air outlet pipe of the air conditioner to the air inlet 7 of the distributor box 1, which can be better applied to different vehicle bodies, has a wider range of applications, and is more convenient to install.
