Abstract
A heat exchanger for a stirling engine 10A of a twin-cylinder α type includes a heat transfer tube group 70A formed with heat transfer tubes 71A causing a working fluid of the stirling engine 10A to flow between a high-temperature cylinder 20 and a low-temperature cylinder 30 arranged linearly and parallel to each other in the stirling engine. The heat transfer tube group 70A includes a rising section G1 extending upward, a falling section G2 extending downward, and a connecting section G3 connecting the rising section G1 and the falling section G2 in a turn-back manner, where the heat transfer tube group 70A is regarded as extending from one end or the other end thereof.
Claims10
A heat exchanger for a stirling engine, comprising
- a tube group comprising a plurality of tubes configured to cause a working fluid of the stirling engine to flow between two cylinders arranged linearly and parallel to each other in the stirling engine, the stirling engine being of a twin-cylinder a type,
- wherein the tube group comprises a rising section extending upward, a falling section extending downward, and a connecting section connecting the rising section and the falling section in a turn-back manner, where the tube group is regarded as extending from one end thereof,
- wherein the rising section is located along a first plane parallel to an aligning direction of the cylinders and an extending direction of the cylinders, and the falling section is located along a second plane parallel to the first plane.
