Where is the air conditioning evaporator located in a car?

Automotive evaporators are generally installed under the dashboard on the passenger side. The car air conditioning evaporator is mounted inside the heater blower, which is a large plastic component containing air ducts, the evaporator, heater core, and other parts. Here is an introduction to automotive evaporators: 1. The car air conditioning evaporator is located inside the vehicle and adopts a direct air-cooled structure. It operates on the principle that low-temperature, low-pressure liquid refrigerant absorbs substantial heat during evaporation, thereby removing heat from the surrounding air to achieve cooling and dehumidification, while delivering cooled air into the cabin to lower the interior temperature. 2. The function of the evaporator is to allow high-temperature, high-pressure liquid refrigerant to enter through the atomization effect of the expansion valve. As the pressure decreases, the atomized refrigerant vaporizes into a gaseous state. During this phase change process, heat absorption occurs. Consequently, the surface temperature of the evaporator drops, and air passing over it becomes cooled.
