Document Type and Number:
WIPO Patent Application WO2002039005
Kind Code:
A8
Abstract:
The present invention relates to a joint for connecting a metal tube and a glass tube. The joint is composed of a metallic part and a glass part. Each part has a through hole. The two parts are sealed together along the periphery of the holes. The joint is used in vacuum heat collecting tube system of a solar energy heating apparatus. A glass tube of the solar energy heating apparatus is sealed to the glass part of the joint and a metallic heat absorber is sealed to the metallic part of the joint. By using the joint according to the present invention, the sealing process and manufacturing device are simplified, the manufacture cost is lowered.
