Spacer for axial parallel fixation of multiple pipe lines at distant from each other, particularly ground source heat pumps forming pipe bundle, comprises internal receptacle for three or multiple pipes placed outside pipe bundle

摘要

The spacer (1) comprises an internal receptacle (16) for three or multiple pipes (5) placed outside a pipe bundle. The spacer has one or multiple braking elements (8) made of a material in a zone for resting against the pipes. The braking element comprises higher friction efficiency than the raw material. The residual spacer is made of raw material.
