The heat exchanger (1) has a prim. side (1a) through which flows a heat-emitting fluid, and a sec. side (1B) which has an inlet (10) and an outlet (11) and is flowed through by a heat-absorbing fluid. The heat-absorbing fluid temp. is monitored by an indicator (14) on the sec. side outlet and compared in a control unit (6) with a pre-set temp. theoretical value. If the monitored temp. is less than the theoretical value, the control unit increases the heat-emitting fluid flow on the prim. side, and if the monitored value exceeds the theoretical value, the control unit reduces the flow. |
