The turbulator has a partial annular disc (40) lying in a plane that is arranged in an angle to an orthogonal plane of a longitudinal axis of an earth probe (20). A middle point lies on the longitudinal axis, and an inner edge for fastening annular disc to an inner pipe outer surface (58) of a probe inner pipe (30). Outer diameter of the turbulator is smaller or equal to an internal diameter of a probe outer pipe (32). Two neighboring partial annular discs are arranged along the longitudinal axis. An independent claim is also included for a method for manufacturing a partial annular disc. |
