PURPOSE:To reduce the weight of the device and eliminate a joint from a tube conducting primary operating fluid. CONSTITUTION:A conduit 5 for conducting the liquid of primary operating fluid is constituted of a continuous plastic tube having flexibility while a heat dissipating body 11, contacting with the gas of secondary operating fluid, is mounted on the outer periphery of the conduit 5. The heat dissipating body 11 is constituted of a tubular body 12, through which the conduit 5 is penetrated so as to be contacted closely, and a plurality of heat dissipating fins 13, formed integrally with the outer surface of the tubular body 12. Accordingly, a heat exchanging device, light in weight, convenient in handling, inexpensive in price, having no coupling, readily causing the leakage of liquid, and easy in quality control, can be obtained. |
