Air conditioner for vehicle
View Patent ↗Provided is an air conditioner for a vehicle, including a blower unit that blows air, an air conditioning case including an evaporator and a heater core, which are sequentially disposed in an airflow path, and an air inlet path that allows air to flow to an evaporator from the blower unit, wherein the airflow path includes a first path that allows air entered from the air inlet path to flow to a lower part of the evaporator and second and third paths that allow the air to flow to the lower part of the evaporator after passing through both sides of the evaporator. The air conditioner increases an amount of airflow and reduces airflow resistance since airflow paths are formed on both sides of the evaporator in addition to a direction perpendicular to the separator. Consequently, the airflow entering a lower part of the evaporator can be uniformly distributed.
1. An air conditioner for a vehicle, comprising:
a blower unit that blows air toward an evaporator; and
an air conditioning case which includes
the evaporator and a heater core sequentially disposed in an airflow path, and
an air inlet path that allows air to flow to the evaporator from the blower unit,
wherein the air conditioning case includes
a first path that allows air entered from the air inlet path to directly flow to a lower part of the evaporator, and
second and third paths that allow the air entered from the air inlet path to flow to the lower part of the evaporator after passing along both lateral sides of the evaporator; and
wherein the second and third paths are respectively disposed on the lateral sides of the evaporator and are connected to the first path.
2. The air conditioner for a vehicle of claim 1 , wherein the first path includes
a cooling path that passes through a portion of the evaporator, and
a detour path that detours the evaporator.
3. The air conditioner for a vehicle of claim 1 , wherein the second and third paths are guide conduits protruding outward from both lateral sides of the air conditioning case.
4. The air conditioner for a vehicle of claim 1 , wherein
a portion of the air inlet path is blocked by an upper tank of the evaporator, and
the evaporator is mounted at a slope in a direction from the upper tank to a lower tank of the evaporator.
