<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of easily unifying flow division, being sufficiently miniaturized as the whole heat exchanger including flow dividers on inflow side and flow mergers on outflow side, and being installed in a product such as a water heater without restriction on a water circuit. <P>SOLUTION: The heat from carbon dioxide can be transferred to the water flowing from the approximately whole of a porous tube 2 to the inside of a variant form-tube 4 kept into contact with the porous tube 2, and further almost the flow divider 5, and the merger 6 of the porous tube 2 and the flow divider 7, and the merger 8 of the variant form-tube 4 are placed in the same coil by winding the porous tube 2 and the variant form-tube 4 together into the coil shape, thus the heat exchanger main body 1 can be miniaturized as a whole. Further a heat insulating material may be attached integrally with the flow divider 5, and merger 6 of the porous tube 2 and the flow divider 7, and merger 8 of the variant form-tube 4, thus the heat insulating material attached to the heat exchanger 1 can be simplified, and sufficiently miniaturized, and the working efficiency in attaching the heat insulating material can be improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
