Title:
GROUND COLLECTOR FOR A HEAT PUMP AND MILLING CUTTER FOR MILLING A SLIT IN THE GROUND
Document Type and Number:
WIPO Patent Application WO/2012/000583
Kind Code:
A3
Abstract:
The invention relates to a ground collector suitable for a heat pump and a milling cutter for forming a ground collector, comprising a slit (100a, 100b, 100c), which is milled into the ground (500) and which has a length (L1) and a width (B1) and a depth (T1), comprising a ground collector device (200), wherein two main sides (110) define the width (B1) of the milled slit (100a, 100b, 100c), wherein a bottom (110) defines the depth (T1) of the milled slit (100a, 100b, 100c), and wherein a first end face (130) and a second end face define the length (L1) of the milled slit (100a, 100b, 100c), wherein the length (L1) of the milled slit (100a, 100b, 100c) is bounded in the vicinity of the first end face (130) by an obstacle (510, 520, 200h), comprising a first area (a) of the milled slit (100a, 100b, 100c) for positioning the ground collector device (200), wherein the first area (a) is distanced from a ground surface (550) of the ground (500) by at least one second area (b), wherein in the vicinity of the obstacle (510, 520, 200h) the first end face (130) is predominantly perpendicular down into the first area (a) relative to the ground surface (550) of the ground (500), and wherein the ground collector device (200) is positioned in the milled slit (100a, 100b, 100c) in the first area (a) on the predominantly perpendicular first end face (130).
