Title
(EN) HEAT EXCHANGER FOR STIRLING ENGINE AND STIRLING ENGINE USING THE SAME
(FR) ÉCHANGEUR THERMIQUE POUR MOTEUR STIRLING ET MOTEUR STIRLING ASSOCIÉ

Abstract
(EN)
A Stirling engine in which a working mixture is reciprocatingly moved between a compression space and an expansion space by a piston and a displacer. Each of a high temperature side internal heat exchanger and a low temperature side internal heat exchanger disposed between the compression space and the expansion space of the Stirling engine and transmitting a heat heat-exchanged with the working mixture to a high temperature side heat transfer head and a low temperature side heat transfer head is formed of the heat exchanger of this invention. In the heat exchanger, a large number of fins extending to the center of a ring are formed on the inner surface of a ring-shaped base. A retaining ring is press-fitted to cylindrical spaces formed between the tips of the fins.
(FR)
La présente invention concerne un moteur Stirling dans lequel un mélange de travail est déplacé en va-et-vient entre un espace de compression et un espace de dilatation par un piston et un piston auxiliaire. Chacun d’un échangeur thermique interne côté haute température et un échangeur thermique interne côté basse température disposés entre l’espace de compression et l’espace de dilatation du moteur Stirling et transmettant une chaleur échangée thermiquement avec le mélange de travail à une tête de transfert thermique côté haute température et une tête de transfert thermique côté basse température est formé de l’échangeur thermique de la présente invention. Dans l’échangeur thermique, un nombre important d’ailettes qui s’étendent jusqu’au centre d’un anneau sont formées sur la surface intérieure d’une base annulaire. Un anneau de retenue est ajusté avec serrage sur des espaces cylindriques formés entre les embouts des ailettes.

 スターリング機関はピストン及びディスプレーサにより圧縮空間と膨脹空間の間で作動ガスを行き来させる。圧縮空間と膨脹空間の間に配置され、作動ガスとの間で熱を授受した熱を高温側伝熱ヘッド及び低温側伝熱ヘッドに伝える高温側内部熱交換器と低温側内部熱交換器は、いずれも本発明に係る熱交換器により構成される。熱交換器は、リング状ベースの内面に、リングの中心方向に向かって延びる多数のフィンを形成したものである。フィンの先端同士の間に形成される円筒形の空間には留めリングが圧入される。
