To provide a multistage type heat exchanger, a method of using the same and a refrigerator incorporating its multistage type heat exchanger thereinto in such consideration that there is resistance in circulation of refrigerant at every heat exchanger and such circulation lacks smoothness.SOLUTION: In order to attenuate a high pressure of refrigerant by means of at least primary and secondary heat exchanges and produce condensate again by means of the secondary and tertiary heat exchanges, multiple tubes formed at intervals concentrically are provided, a first channel formed of an inlet of refrigerant which is ejected from a compressor and is caused to pass through a condenser on one end and an outlet thereof, formed on the other end is formed, a first outer channel connecting to a second channel formed on the inside of the first channel from refrigerant outlet of the first channel is formed, this constitution is plurally continued in succession, such circulation of refrigerant to respective intervals of the multiple tubes is performed and a central tube of the multiple tube is used as the channel of fluid for facilitating condensation action of refrigerant.SELECTED DRAWING: Figure 1 【課題】 冷媒の流通に各熱交換器ごとに抵抗があり、スムーズさに欠けるという問題点があった。【解決手段】 少なくとも第一次、第二次の熱交換で冷媒の高圧を減衰させ、少なくとも第二次と第三次の熱交換で再び凝縮液の生成をするために、同心円状に間隔をもって形成されている多重管を有し、その多重管の最外間隔には圧縮機から吐出され、凝縮器を通過した冷媒の入口を一端に形成し、他端に出口を形成した第一流路を形成し、その第一流路の冷媒出口からは第一流路の内側に形成された第二流路へと連結する第一外流路を形成し、この構成を順次複数連続して、多重管の各間隔に一連に冷媒を流通させる構成とし、前記多重管の中心管は、冷媒の凝縮液化作用を促進させるための流体の流路としてあることとする。【選択図】 図１
