Dewatering mildew-proof device of vehicle air-condition evaporator and dewatering mildew-proof method thereof

Abstract

The invention relates to a dewatering mildew-proof device of a vehicle air-condition evaporator; and the non-ventilation surface of the vehicle air-condition evaporator is provided with a dewatering mildew-proof device which is formed by pipelines. The invention also discloses a dewatering mildew-proof method of the dewatering mildew-proof device of the vehicle air-condition evaporator. The dewatering mildew-proof device is arranged on the non-ventilation surface of the vehicle air-condition evaporator, circular flow high-temperature engine cooling liquid flows through the dewatering mildew-proof device, the circulation of the engine cooling liquid is controlled by a vehicle body controller in real time, heat of the engine cooling liquid is transferred to the vehicle air-condition evaporator to evaporate surface condensate water of the vehicle air-condition evaporator in a heat absorption mode, and the surface condensate water of the vehicle air-condition evaporator is removed in timeto prevent mildew.

Description

technical field [0001] The invention relates to a vehicle air conditioner evaporator, in particular to a water and mildew removal device for a vehicle air conditioner evaporator and a method for removing water and mildew. Background technique [0002] According to its function, the automobile air conditioning system can be divided into five basic components: refrigeration system, heating system, ventilation system, control and manipulation system and air purification system. Among them, the refrigeration system is to cool the air in the passenger compartment or the fresh air entering the passenger compartment from the outside to achieve the purpose of reducing the temperature in the passenger compartment. The temperature of the evaporator as a cold source is lower than the dew point temperature of the air, so the refrigeration system also has the functions of dehumidification and air purification. The warm air system generally introduces the coolant of the engine into the h...

AI Technical Summary

Problems solved by technology

[0003] When the car air conditioner is cooling, because the temperature of the air conditioner evaporator is low (0-3 degrees), a large amount of water droplets will condense on the surface of the air conditioner evaporator, although the heating, ventilation and air conditioning unit HVAC (Heating, Ventilation and Air Conditioning Unit) There is a drainage device, but due to the adsorption force of the heating ventilation and air conditioning unit HVAC, the water droplets on the air conditioning evaporator cannot be completely drained in time

At the same time, because the air filter has certain limitations on air filtration, the evaporator of the air conditioner with condensed water is easy to absorb dust and other dirt. After the air conditioner is turned off, the remaining water droplets and the adsorbed dust will undergo a chemical reaction. Especially in summer, the temperature inside the car is high and the chemical reaction is fast. When the air conditioner is turned on again, the wind blowing out in the first few minutes will have a musty smell, which seriously affects the comfort of the whole car.
