Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning guide, in particular to an automobile air-conditioning guide structure. Background Art

[0002] Usually, when the car air conditioner starts working, the blower sucks air from inside or outside the vehicle, and the blower sucks air into the volute through the air inlet to form an air flow, which flows through the evaporator along the internal flow channel of the volute; however, due to the air conditioning structure, the air flow at each position of the internal flow channel of the volute is not uniform (especially, when the total volume of the volute design is small, the curvature of the internal flow channel of the volute is usually large). At this time, when the blower throws out the air flow and flows into the evaporator along the volute flow channel, the air flow is very likely to be concentrated on the flow channel in a certain direction. When the air flow flows through the evaporator, it will be concentrated in an area of ​​the evaporator, resulting in slow cooling efficiency, uneven air outlet temperature, and uneven air volume; the main working modes of the car air conditioner at present are complex modes such as face blowing, foot blowing, defrosting, face blowing and foot blowing, and foot blowing defrosting. When the car air conditioner is operating in each mode, if the air outlet cannot discharge air normally or the air outlet temperature is uneven, the air volume is uneven, and the cooling time is long, the comfort of the cabin will be reduced and even safety will be affected.

[0003] After searching, the applicant found that the Chinese patent document with publication number CN117190473A disclosed an anti-condensation air-conditioning guide device and air conditioner on December 8, 2023, which relates to the field of air-conditioning technology.
