Abstract
A concentric pipe geothermal heat exchanger well head is described. The well head may include a riser pipe having an outer pipe and an inner core pipe, wherein an inner heat exchanger pipe is coupled to the inner core pipe, a reducer coupled to an outer heat exchanger pipe on one side and coupled to the outer pipe on a second opposite side to conduct fluid between the outer heat exchanger pipe and the outer pipe, a flow pipe parallel to and biaxial with the riser pipe configured to be coupled to a geothermal heat pump, and an elbow coupled to the outer pipe to couple fluid between the outer pipe and the well head pipe.
Claims7
A well head interconnecting a concentric pipe ground heat exchanger to a geothermal heat pump, the geothermal heat pump having biaxially-arranged supply and a return flow pipes, wherein the supply flow pipe is biaxially-arranged relative to the concentric pipe ground heat exchanger with the return flow pipe coaxially-arranged, the concentric pipe ground heat exchanger having an outer heat exchanger pipe configured to convey a heat exchange fluid in a first direction and an coaxially arranged inner heat exchanger pipe configured to convey the heat exchange fluid in a second direction, the outer heat exchanger pipe having a first radius, which is associated with a borehole radius of the heat exchanger, and the inner heat exchanger pipe having a second radius, wherein the second radius is smaller than the first radius, the well head comprising:
- an outer riser pipe of a third radius smaller than the first radius and larger than the second radius;
- an inner riser pipe fluidically interconnected to the inner heat exchanger pipe;
- a first reducer fluidically interconnected to the outer heat exchanger pipe on one end and to the outer riser pipe on an opposite end;
- a second reducer coupled to the outer riser pipe and fluidically interconnected to the inner riser pipe on one end and to a third reducer on an opposite end, the third reducer fluidically interconnected to the return flow pipe of the geothermal heat pump;
- and
- an elbow fluidically interconnected to the outer riser pipe on one end and to the supply flow pipe of the geothermal heat pump on an opposite end, wherein a distance from the center of the outer riser pipe to a distal side of the elbow is not greater than the first radius.
