Nozzle i.e. dual nozzle, for use in manufacturing system to deliver liquid nitrogen into halogen lamp utilized in passenger car for illumination purposes, has protective gas pipe whose outer side portion is heated by heater

摘要

#CMT# #/CMT# The nozzle (1) has a protective gas pipe (2) supplying protective gas, and a medium pipe (3) guiding medium such that the medium that is discharged from the medium pipe is surrounded by protective gas. A portion of an outer side of the protective gas pipe is heated by a heater (4). A heat insulation unit (20) is provided between the protective gas pipe and the medium pipe that supports the heat insulation unit. The heat insulation unit is designed as a tubular piece and controlled by a temperature sensor. #CMT#USE : #/CMT# Nozzle i.e. dual nozzle, for use in a manufacturing system for delivering cold medium i.e. low-cold medium e.g. liquid nitrogen (all claimed) into halogen lamp, that is utilized in a passenger car for illumination purposes. Can also be used for delivering liquid medium. #CMT#ADVANTAGE : #/CMT# The heat insulation unit is provided between the protective gas pipe and the medium pipe, thus avoiding formation of an ice layer in a reliable manner using reduced heat, and hence delivering cold medium into the halogen lamp in a reliable manner and increasing efficiency of the nozzle. The heat insulation unit is made of fluoroplastic, PTFE, polytrifluorochloroethylene, polymide, polyolefin, polyethylene or vinyl polymers and PVC so as to achieve sufficient thermal stability in the nozzle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a nozzle. 1 : Nozzle 2 : Protective gas pipe 3 : Medium pipe 4 : Heater 20 : Heat insulation unit #CMT#METALLURGY : #/CMT# The outer side of the protective gas pipe is made of copper. #CMT#POLYMERS : #/CMT# The heat insulation unit is made of fluoroplastic, PTFE, polytrifluorochloroethylene, polymide, polyolefin, polyethylene or vinyl polymers and PVC.
