Abstract (en)

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.

The present invention relates to a heat recovery battery (1) with a plurality of circuits (10), placed above each other, through which a heat transferring liquid circulates. The circuits comprise horizontal exchanger tubes (12), provided with ribs (15), which exchanger tubes within a circuit in the form of a vertical row or several adjacent vertical rows are connected to each other via row bends (13), located at the ends of the circuits, to row circuits (12), which in their turn in a horizontal direction are connected to an entire circuit via circuits bends (14) at the highest and the lowest points of the row circuits, the inlets and the outlets of the circuits respectively through connecting tubes (9 and 11 respectively) being connected to collecting tubes (3 and 5 respectively) on the inlet and the outlet side respectively, which connecting tubes are provided with discharge and aeration means respectively (18 and 19). According to the invention each formation of said circuit bends (14) to row circuits (12), located vertically above each other and consequently also the last-mentioned row circuits per se being connected to each other via a through connecting tube (16) with aeration and discharge means respectively (17).
