Description

Technical Field

[0001] The invention relates to the technical field of automobile air conditioners, and in particular to a water filtering unit component and a liquid water filtering device for an automobile air conditioner condenser evaporator. Background Art

[0002] The automobile air conditioning system is one of the core key systems of the automobile. It can timely adjust the key parameters such as temperature, humidity, cleanliness, etc. of the air delivered to the cabin to ensure the riding comfort of passengers. So far, the installation rate of air conditioning in domestic cars has achieved full coverage.

[0003] In the automobile air conditioning system, the evaporator transfers the heat of the airflow through the air conditioning duct by using the phase change of the refrigerant from liquid to gas in its pipeline, thereby reducing the airflow temperature and realizing the cooling and dehumidification function of the air conditioning system. When the humidity in the air intake outside the car is high, a large amount of condensed water will be generated on the surface of the evaporator heat dissipation pipe. When a certain amount of air passes through, the large amount of condensed water and small water mist droplets will be brought into the downstream air duct and directly introduced into the cabin through the air outlet pipe of the air conditioner, which deviates from the original intention of dehumidification and seriously affects the consumer experience. At the same time, for new energy vehicles, a heating component will be installed at the rear end of the evaporator, which will cooperate with the evaporator to provide dry, warm and comfortable airflow. The introduction of the above condensed water and small water mist droplets will increase the energy consumption of the heating component and increase the load of the entire thermal management system. Therefore, it is necessary to deal with the condensed water and small water mist droplets generated on the evaporator in a timely manner to avoid affecting the subsequent components and consumer experience.

[0004] Conventional technology generally utilizes the principle of gravity to optimize the design of the evaporator heat dissipation pipe structure, adjusts the appropriate window angle and angle of the evaporator heat dissipation belt (CN 115451614 A), and makes it easier for condensed water to be diverted to the automatic manifold. However, small droplets or water films are still inevitably present on the surface of the evaporator pipe. Under a certain airflow speed, the phenomenon of the condensed water being brought into the downstream air duct still exists. Some patents disclose "an air conditioner anti-blow water structure" (CN 110239313 B), which uses a hydrophobic and hydrophilic filter to intercept condensed water. However, the above device only processes large droplets of condensed water, and does not solve small droplets or water mist, and cannot effectively remove small droplets. Summary of the invention

[0005] In order to intercept condensed water and small water mist droplets downstream of the evaporator in the air duct of an automobile air conditioner, the present invention provides a water filtration unit assembly and a liquid water filtration device for an automobile air conditioner condenser evaporator, which can provide dry air for the automobile cabin and reduce the heat load of the downstream heating components of new energy vehicles.
