PROBLEM TO BE SOLVED: To provide a heat exchanger for heat exchange between two types of fluids, having improved heat efficiency by increasing its heat transfer area and having saved installation space by reducing its size. SOLUTION: An opening hole 21 is formed in the bottom of a container 20 molded into an oblong vessel container, at one side end. A required number of containers 20 are stacked alternately turning their directions rightward and leftward and joined at their stacked peripheral edges with air tightness into a stacked structure to form one fluid passage ranging from the uppermost stage to the lowermost stage (or from the lowermost stage to the uppermost stage). A tubing is spirally wound on the stacked structure and joined to both side walls of the container to form the other fluid passage. COPYRIGHT: (C)2004,JPO |
