Technical Field
[0001] The utility model relates to the technical field of air-conditioning evaporators, in particular to a drainage device for an automobile air-conditioning evaporator. Background Art
[0002] The air conditioner evaporator is a key component in air conditioning systems. Its function is to achieve cooling by evaporating a low-temperature liquid refrigerant at low pressure, transforming it into vapor and absorbing heat from the medium being cooled. In the air conditioner's refrigeration cycle, the evaporator is typically located in the indoor unit, responsible for absorbing heat from the indoor air and lowering the indoor temperature.
[0003] In existing automotive air-conditioning evaporator drainage devices, the angle of the drainage pipe is usually fixed and may not be adjusted according to actual needs. The fixed-angle drainage pipe may also not be able to adapt to different installation locations and vehicle models, limiting its versatility. In some special vehicle usage scenarios, such as driving on rugged roads or in extreme weather conditions, the fixed-angle drainage pipe may not be able to effectively drain condensed water, thereby affecting the normal operation of the air-conditioning system.

This connection method is simple and reliable, easy to install and disassemble, and can also effectively prevent water leakage.
[0009] As a further improvement of the above solution, a positioning shaft is inserted into the inner wall of the positioning hole, and one end of the positioning shaft is fixedly connected to a mounting ring.
[0010] As a further improvement of the above solution, there are several positioning shafts, and the several positioning shafts are located on the inner wall of the positioning hole. The mounting ring is plugged into the clamping ring.
[0011] Through the above technical solution, by setting the positioning hole and the positioning axis, the user can adjust the angle of the positioning axis in the positioning hole, thereby adjusting the drainage angle of the drainage pipe. This combination increases the flexibility of the device and can adapt to different vehicle usage scenarios and environments.
