Description

ABSTRACT:
The present invention provides an improved liquid conduit for a device such as a solar collector. A tube of stretchable material carries the liquid. A rigid elongate channel has side walls in contact with and enclosing the tube about at least 50% but not the entirety of its circumference. The channel allows the tube to expand radially along part of its circumference when the liquid expands due to freezing.
