<p><P>PROBLEM TO BE SOLVED: To provide a Stirling engine heat exchanger for reducing a dead space, by improving heat transmission efficiency, without increasing a pressure loss. <P>SOLUTION: This Stirling engine heat exchanger includes a regenerated heat exchanger 5 and a low temperature heat exchanger 6 concentrically arranged around four cylinders 3, and includes a high temperature heat exchanger 7 arranged in the adjacent cylinders 3 and constituted of a plurality of heat transfer tubes 7a for connecting between the cylinders 3, and is formed as a structure that a compression space 10 constituted of the cylinders 3 and one end 9a of a piston 9 of these cylinders 3, is adjacent to the low temperature heat exchanger 6 in an inside space of the low temperature heat exchanger 6. The compression space 10, the low temperature heat exchanger 6, the regenerated heat exchanger 5, the high temperature heat exchanger 7 and an expansion space 11 form a closed flow passage of four systems by connecting the high temperature heat exchanger 7 to the expansion space 11 constituted of the adjacent cylinder 3 of the cylinders 3 forming the compression space 10 and one end 9b of the piston 9 of this adjacent cylinder 3 in an inside space of the regenerated heat exchanger 5, and are constituted so that the plurality of heat transfer tubes 7a of the high temperature heat exchanger 7 are connected in an equal arrangement position on a concentric circle to the expansion space 10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
