<p>PURPOSE:To elevate the temperature of a coolant at a discharging pipe of coolant higher than that obtained in a conventional method and to obtain a highly useful heat source, by dividing a tank and supplying a coolant from the downstream side with respect to the advancing direction of a strip and extracting it from the upstream side. CONSTITUTION:A coolant 3 in a tank 2 is agitated by a running metallic strip 1 as a driving force, and a dividing board 10 acts to divide the coolant 3 in two by separating the agitation into a line A side and a line B side. Accordingly the temperature of coolant 3 is made to be T1>T2, where T1 is a temperature at the line A side and T2 at the line B side. Further, by supplying a coolant 9 from the line B side and extracting it from the line A side, a sensible heat higher in temperature compared with that obtained in a conventional method, that is, higher in usefulness can be recovered.</p> |
