Description

Air flow guiding device of passenger car air conditioner evaporator Technical Field The utility model relates to the technical field of evaporators, in particular to an air flow guiding device of a passenger car air conditioner evaporator. Background The automobile air conditioner refrigerating system mainly comprises a compressor, a condenser, a liquid storage device, an expansion valve, an evaporator, a fan, a pipeline, a control part and the like, when the air conditioner refrigerating system is opened, the air conditioner compressor starts to operate and sends refrigerant to the evaporator, the evaporator is cooled by the refrigerant, air from a blower is cooled, and then cool air is sent into a carriage through the fan and the pipeline for cooling. When the air conditioner is installed on a passenger car, the passenger car air conditioner is required to provide larger cold air flow because the inner space is large, a pair of evaporators are symmetrically installed on the left and right sides of the air conditioner installation assembly, a fan is installed at an air conditioner air port corresponding to each side of the evaporators, the air cooled by the evaporators is brought into a carriage by the suction force of the fan, but in actual use, condensed water is easy to generate on the surfaces of the evaporators, if the condensed water is directly flushed by high-speed air flow, and the condensed water can be brought into the carriage to cause dampness or peculiar smell. Disclosure of utility model The utility model aims to solve the technical problem that condensed water is easy to generate on the surface of an evaporator, and if the condensed water is directly flushed by high-speed air flow, the condensed water can be possibly brought into a carriage to cause dampness or peculiar smell. The utility model adopts the following technical scheme for realizing the purposes: an air flow guiding device for a passenger car air conditioner evaporator, comprising: The mounting plate is provided with a pipeline communicated with the output end of the external evaporator; The gas-liquid separation mechanism is arranged at the end part of the pipeline and is used for separating condensed water mixed in the cooling gas.
