APPARATUS FOR MANUFACTURING GEOTHERMAL PIPE OF GEOTHERMAL HEAT EXCHANGER

摘要

PURPOSE: A device for manufacturing geothermy pipe is provided to rapidly manufacture a bent meandering type geothermy pipe in order to have a curvature of the outer circumference of a cylindrical pile because the plastic-deformation of a synthetic resin pipe is performed. CONSTITUTION: A device(10) for manufacturing geothermy pipe is composed of a mold(11) and heating unit(23). A plurality of first arc shaped units being opened in a first direction and a plurality of second arc shaped units being opened in a second direction facing to the first direction are arranged in the mold as a zigzag form. The plurality of first arc shaped units and plurality of second arc shaped units are connected to a plurality of connection units. The heating device heats a synthetic resin pipe accommodated in the mold, thereby performing the plastic-deformation of the synthetic resin pipe as a shape corresponding to an accommodation groove shape.
