PURPOSE:To obtain a simple apparatus with reduced running cost by gathering comparatively short metal cans with small cross sections filled with liquid respectively with gaps remained among each other for moving into low temperature air after being brought in contact with hot air in their outsides to accumulate heat. CONSTITUTION:Short metal containers 10 of comparatively small capacity with water enclosed are gathered, and each lid-binding part 11 is set on the lid binding part 11 of the neighbouring container 10. Horizontal and vertical gaps are maintained between gathered metal cans neighbouring with each other, and hot air is supplied into these gaps. This construction serves to obtain a heat exchanger in which mutual heat-exchanging efficiency between the whole amount of water contained in cans and the temperature of ventilation is highly promoted and the specific heat of contained water can be sufficiently used almost in a whole amount with reduced equipping and running costs. |
