Title Structure design of air purification equipment for vehicle
Abstract
The structure design of the car air purification device in the subject,is designed for a small bus with a set of intelligent detection and control functions,external circulation is used to be ventilation to air inside the car,and internal circulation purification and escape function in one of the environmental protection intelligent skylight,is the effective way to solve air pollution in car. In the subject ,according to the air exchange quantity of the fresh air inside the bus,the circulation and the outer circulating air duct of the purification device are calculated,determine duct dimensions and appearance shapes,used to determine the installation position,used 3D modeling software to modeling,and used 2D graphics software complete the 2D engineering drawings.Finally,complete 3D model assembly,and strength check to key parts.So then improve automation,intelligent level and practical validity of the environmental intelligence skylight.Realize the full purification of air in the car and save space of the car,improvement environmental protection and practical performance of the passenger car overally.
Keywords Air purification equipment for vehicle internal circulation External circulation Practical and environmental protection
