Abstract

The invention provides a fresh air pipe and a forming process thereof.The forming process of the fresh air pipe comprises the following steps that S1, an oval pipe mold with the oval cross section is obtained, and an extrusion machine head is arranged on the periphery of one end of the oval pipe mold; s2, the oval tube mold is controlled to rotate and pass through the extrusion machine head; and S3, the plastic in the molten state is extruded to the oval pipe mold through the extrusion machine head, so that the fresh air pipe is formed. According to the forming process of the fresh air pipe, the problems that when an existing fresh air pipe of a fresh air conditioner is formed, the inner wall is uneven, so that wind resistance is large, and noise is large can be solved.

Description

technical field [0001] The application relates to the technical field of air-conditioning duct manufacturing, in particular to a fresh air duct and its forming process. Background technique [0002] In recent years, with the introduction of fresh air conditioning systems, people have put forward higher requirements for indoor air quality and installation experience. For the sake of avoiding drilling, the fresh air ducts of existing fresh air conditioners usually use higher utilization rates. oval tube. [0003] Existing elliptical pipes are generally formed by blow molding. When the elliptical pipe is blown, it is easy to form uneven pipe inner walls. Such elliptical pipes have large wind resistance and are prone to noise, which affects user experience. SUMMARY OF THE INVENTION [0004] The present application provides a fresh air duct and its forming process to solve the problems of large wind resistance and high noise caused by uneven inner walls when forming the fresh ...
