<p>The fluid-coupled heat exchanger with venting and tapping-off devices involves a heat recovery battery with several superimposed circuits, through which heat-transmitting fluid circulates. The circuits comprise horizontal exchange tubes (12) provided with lamellas (15), which within a circuit in the form of a vertical row or several laterally located vertical rows are connected with each other via end-located row bends (13) to row circuits. The row circuits are in turn coupled together in a horizontal direction to a whole circuit via circuit bends (14) at the highest and lowest points of the row circuits. The inlet and outlet of the circuits are connected via connecting tubes (9,11) to collection tubes (3,5) on the inlet and outlet sides. The collection tubes are provided with tapping-off and venting devices.</p> |
