Description

Technical Field

[0001] This utility model relates to the field of air conditioner evaporator technology, specifically to an air distribution component for an air conditioner evaporator. Background Technology

[0002] The air conditioner evaporator is a key heat exchange component in the refrigeration system. It exchanges heat with the air flowing over the fin surface through the low-temperature refrigerant circulating inside, thereby achieving the purpose of cooling the air. This process plays a decisive role in the cooling efficiency and performance of the air conditioner.

[0003] Traditional air conditioner evaporators have significant shortcomings in airflow organization, often resulting in uneven air delivery and uneven airflow distribution between the fins, leading to excessive airflow in some areas and insufficient airflow in others.

[0004] Uneven airflow can cause localized temperature variations on the evaporator surface, and even create heat exchange dead zones. This not only reduces heat exchange efficiency and affects the overall cooling effect, but also increases energy consumption and may cause problems such as poor condensate drainage.

The frame serves as a basic structure for support and fixation. The symmetrically arranged side plates are used to install the heat dissipation fins and connect the pipes. The core function of the heat dissipation fins is to expand the heat exchange area and enhance air heat conduction. The input pipe is responsible for introducing the cooling medium into the system, while the output pipe discharges the medium after heat exchange.

The frame 1 serves as a basic support structure, and the side plates 2 are symmetrically fixed and used to install the heat dissipation fins 6. The heat dissipation fins 6 expand the heat exchange area to enhance air heat conduction. The input pipe 3 is responsible for introducing the cooling medium, and the output pipe 4 is responsible for discharging the medium that has completed heat exchange. The heat exchange pipe 5 penetrates the interior of the heat dissipation fins 6 to realize the heat transfer between the refrigerant and the air.

[0027] A connecting frame 7 is fixedly installed at the end of the frame 1 away from the heat dissipation fins 6. A flow equalization plate 8 is movably installed inside the connecting frame 7. Several through holes are provided on the flow equalization plate 8. Sealing strips 9 are provided at the upper and lower edges of the flow equalization plate 8. Several pins 10 are movably installed at the upper and lower ends of the flow equalization plate 8. A baffle 11 is fixedly installed at the end of each pin 10 near the flow equalization plate 8. A movable groove 12 is provided inside the flow equalization plate 8. A spring 13 is fixedly installed between the baffle 11 and the inner wall of the movable groove 12. The frame 7 is used to connect the air duct and accommodate the flow equalization plate 8. The flow equalization plate 8 achieves uniform airflow distribution through surface through holes. Sealing strips 9 are provided on the upper and lower edges of the flow equalization plate 8 to ensure airtightness. The pin 10 is movably set at the upper and lower ends of the flow equalization plate 8 for locking position. A baffle 11 is fixed at the end of the pin 10 near the flow equalization plate 8 to limit its range of movement. The movable groove 12 is opened inside the flow equalization plate 8 to accommodate the pin 10 and the spring 13. The spring 13 provides elasticity so that the pin 10 can automatically reset and lock.

[0028] The inner wall of the connecting frame 7 has several holes 14 corresponding to the pins 10. An air duct 15 is fixedly installed at the end of the connecting frame 7 away from the heat sink fins 6. A connecting plate 16 is fixedly installed on one side of the air duct 15. Fixing seats 17 are fixedly installed on both sides of the connecting plate 16. A cross-flow fan 18 is movably installed inside the fixing seat 17. A motor 19 is fixedly installed at one end of the fixing seat 17. The output shaft of the motor 19 is connected to the cross-flow fan 18 through a coupling.

The cross-flow fan 18 rotates to generate uniform airflow. The motor 19 drives the cross-flow fan 18 to operate through its output shaft.

[0029] Working principle: The motor 19 drives the cross-flow fan 18 to rotate and generate airflow. The airflow is guided by the air duct 15 and enters the interior of the connecting frame 7. The flow equalization plate 8 distributes the airflow evenly through multiple through holes on its surface. The airflow after being equalized passes through the gaps of the heat dissipation fins 6 and exchanges heat with the internal heat exchange tube 5. The cooling medium enters the heat exchange tube 5 from the input pipe 3, absorbs heat and is discharged from the output pipe 4, completing the refrigeration cycle. The installation process is to push the flow equalization plate 8 into the interior of the connecting frame 7. During the pushing process, the pin 10 is squeezed by the inner wall of the connecting frame 7 and moves into the movable groove 12, which drives the baffle 11 to compress the spring 13. Continue to push the flow equalization plate 8 until the pin 10 is aligned with the insertion hole 14. At this time, the spring 13 rebounds and pushes the pin 10 into the insertion hole 14 to complete the fixation. The baffle 11 restricts the pin 10 from coming out. The sealing strip 9 enhances the sealing between the flow equalization plate 8 and the connecting frame 7.
