Air inlet and air exchange integrated machine for automobile

Abstract

The invention relates to an air inlet and air exchange integrated machine for an automobile. The integrated machine is suitable for air inlet and air exchange in the automobile and various vehicles for air circulation. The integrated machine comprises a draught fan installing plate, a first draught fan, a second draught fan, an in-vehicle main air duct, a first in-vehicle branch air duct, a second in-vehicle branch air duct, a draught fan air inlet connecting pipe, a first air inlet and outlet pipe, a second air inlet and outlet pipe, an evaporator, a cold air heater, a temperature control valve, an internal circulation control valve and an external circulation control valve; the two ends of the draught fan air inlet connecting pipe are connected with an air inlet of the first draught fan and an air inlet of the second draught fan respectively, one end of the first air inlet and outlet pipe is connected with the air inlet of the first draught fan, and the other end of the first air inlet and outlet pipe is connected with the in-vehicle main air duct; the evaporator, the cold air heater and the temperature control valve are installed in the in-vehicle main air duct; an outlet of the in-vehicle main air duct communicates with the first in-vehicle branch air duct; one end of the second air inlet and outlet pipe is connected with an air outlet of the second draught fan, and the other end of the second air inlet and outlet pipe is connected with the exterior of the vehicle; one end of the second in-vehicle branch air duct is connected with the second air inlet and outlet pipe, and the other end of the second in-vehicle branch air duct is connected into the vehicle.

Description

Technical field [0001] The invention relates to an automobile air intake and ventilation integrated machine, which is suitable for air intake and ventilation in automobiles and various vehicles, and air circulation is performed. Background technique [0002] At present, the ventilation in the car is usually carried out by opening the car windows and the car roof sunroof, but it cannot be carried out in rainy weather and winter and when driving on the highway. Although there is a fan installed on the side of the car engine to bring the outside air into the car to improve the car environment, because the car engine generates a lot of heat when it is working, when the outside air enters the car, the heat generated by the engine will be brought into the car. Increase the temperature in the car and affect the air comfort in the car. The turbid air inside the car cannot be directly and effectively discharged outside the car. Summary of the invention [0003] The purpose of the present...

[0002] At present, the ventilation in the car is usually carried out by opening the car window and the roof sunroof of the car, but it cannot be carried out in rainy days and winter and when driving on the highway.

Although there is a fan installed on the side of the car engine to bring the air outside the car into the car to improve the environment inside the car, because the car engine generates a lot of heat when the car engine is working, when the air outside the car enters the car, the heat generated by the engine will be brought into the car. Increase the temperature inside the car and affect the air comfort in the car

The stale air in the car cannot be directly and effectively discharged outside the car
