A recently granted patent (Publication Number: US11912102B2) discloses an innovative air conditioner designed for vehicles. The air conditioner includes an air-conditioning case with an air passageway, a heating heat exchanger for heating the vehicle's interior, and a perforated member, such as an electric heater, with multiple perforated holes. The system also features partition walls that divide the air passageway into multiple sections, with the partition walls extending through the electric heater in the air flow direction and being detachably combined with the perforated member. Additionally, the partition walls are made of a material with higher heat resistance than the air-conditioning case, ensuring durability and efficiency in operation.

Furthermore, the patented air conditioner allows for separate introduction of indoor and outdoor air into the air passageway, which is divided into upper and lower sections by a separation wall. The electric heater in the system includes heat generating units arranged symmetrically in a vertical direction, with a heat radiating unit for exchanging heat with air. The design also incorporates a heater core for heating air using a cooling water heat source, with the electric heater integrated downstream of the heater core in the air flow direction. The system's unique configuration and components aim to enhance heating efficiency, durability, and overall performance in vehicle air conditioning systems.
