Automobile air conditioner with improved discharged air temperature evenness shell and air door structure

Abstract

The invention discloses an automobile air conditioner with an improved discharged air temperature evenness shell and air door structure. The automobile air conditioner comprises a fan, a spiral casingassembly, an evaporator and a warm air assembly, wherein the spiral casing assembly is fixed in the fan through bolts; the inner wall of the fan on the left side of the spiral casing assembly is fixedly provided with the evaporator through bolts; the outer wall of the fan on the left side of the evaporator is fixedly provided with the warm air assembly; a temperature air door is rotatably connected through a rotary shaft in the warm air assembly; a warm air core body is fixed in the warm air assembly above the temperature air door through bolts; a lower half part in the warm air assembly is rotatably connected with a face blowing air door through a rotary shaft; and a foot blowing air door is rotatably connected through a rotary shaft in the warm air assembly above the face blowing air door. By use of the automobile air conditioner with the improved discharged air temperature evenness shell and air door structure, the flow direction of an airflow in a warm air side can be dynamicallychanged and regulated, the mixing evenness of cold air and warm air is improved, and the temperature distribution and the temperature rise evenness of an air outlet can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning equipment, and in particular relates to an automobile air conditioner with an improved air outlet temperature uniformity housing and a damper structure. Background technique [0002] Automobile air conditioner is a device for cooling, heating, ventilating and dehumidifying the air in the compartment. The HVAC assembly of automobile air conditioner is composed of evaporator assembly, warm air assembly and controller, and is the main component to realize air conditioning. The air enters the evaporator assembly through the action of the centrifugal fan, and becomes cold air through the evaporator; while the warm air assembly is provided with a warm air core, and the cold air passes through the warm air core and is heated into warm air. The dampers in HVAC mainly include: blowing face damper, foot blowing damper, defrosting damper, temperature damper. Among them, the temperature d...

AI Technical Summary

Problems solved by technology

Due to the space limitation of the automotive air conditioner assembly, the evaporator core and the warm air core are placed in the same shell assembly and the cold and warm air mixing areas are small, which may easily lead to uneven distribution of air temperature at each air outlet of the air conditioner or the The temperature rise of each air outlet is uneven when the heating and cooling air door in the air conditioner is opened from full cooling to full warm state
