Split type automobile air conditioner

Abstract

The invention relates to a split type automobile air conditioner which is provided with a front shell, a rear shell and a firewall, wherein the front shell is located in a compartment, and a heat exchanger for heating a flowing airflow is arranged in the front shell; the rear shell is positioned in an engine compartment or a motor compartment; and the front shell and the rear shell are connected through a firewall opening. In the air conditioner, from upstream to downstream in an airflow direction, an air inlet, an air blower positioned on the rear shell, an evaporator, upper and lower mixingair doors positioned on the downstream side of the evaporator, a heat exchanger, and upper and lower side air outlets are successively arranged, wherein the airflow from the air blower completely passes through the evaporator. A first plate rib is arranged between the upper mixing air door and the lower mixing air door and divides the airflow from the evaporator into an upper side airflow and a lower side airflow, the upper mixing air door and the lower mixing air door enable the airflow to selectively pass through the heat exchanger, and a second plate rib is arranged on the downstream side of the heat exchanger and guides the downstream airflow of the heat exchanger to the upper side and/or lower side air outlet. A noise reduction requirement in the compartment can be met, and the spacein the engine compartment or the motor compartment can be fully utilized.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a split type automobile air conditioner. Background technique [0002] At present, all vehicles powered by engines (including fuel vehicles, hybrid vehicles, etc.) and some pure electric vehicles use integral water heating air conditioners, and the entire air conditioner is placed in the cockpit. In the heating mode, the coolant flows through the engine or the PTC heater for the waterway and is heated, a part of the hot water (heated coolant) enters the heater core in the air conditioning box, and the blower forces the cold air to exchange with the heater core. The heated air enters the vehicle interior through the air supply channel for heating. In the cooling mode, the temperature of the airflow decreases after passing through the evaporator. After being adjusted by the damper, it will no longer pass through the warm air core, and directly enter the car int...
