摘要： The invention relates to a heat exchanger assembly with at least one multi-pass heat exchanger, comprising a first distributor (1) with a first connection part (1a) for connecting to a fluid line (9), a second distributor (2) with a second connection part (2a) for connecting to a fluid line (9), and at least one first deflection distributor (4), as well as a plurality of tube lines (5) through which a fluid, in particular water, can flow, wherein the first distributor (1) and the second distributor (2) are arranged at one end (A) of the heat exchanger assembly, the deflection distributor (4) is arranged at the opposite end (B) and the tube lines (5) extend from the one end (A) to the opposite end (B), and wherein the first connection part (1a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the first distributor (1) and the second connection piece (2a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the second distributor (2). In order to allow for the heat exchanger assembly to be quickly filled with the fluid and quickly emptied, a third connection part (3) is arranged on the first distributor (1) and/or on the second distributor (2) at a highest point (H) or at least near to the highest point (H) of the respective distributor (1 or 2), and at least one ventilation opening (10) is provided at a highest point (T) or at least near to the highest point (T) of the deflection distributor (4) for pressure equalisation with the environment.

摘要： The invention relates to a heat exchanger arrangement having at least one multipass heat exchanger, which comprises a first distributor (1), a second distributor (2) and at least one tubular diverter distributor (4) having a predefined tube cross-section (AU), and a tube arrangement (25) having a plurality of tubes (5) which are at least substantially parallel to one another and have a predefined tube cross-section (AR), through which a fluid—particularly, water—can flow and which are arranged in the tube arrangement (25) in columns with a predefined number of columns (n), wherein the first distributor (1) and the second distributor (2) are arranged at one end (A) of the heat exchanger arrangement and the diverter distributor (4) is arranged at the opposing end (B), and the tubes (5) extend from the one end (A) to the opposing end (B) and are connected to the diverter distributor (4) and the first or the second distributor (1, 2), and at least one vent opening (10) is arranged at a highest point (T), or at least in the vicinity of the highest point (T), of the diverter distributor (4) to equalize the pressure with the surroundings. In order to enable rapid filling of the heat exchanger arrangement with the fluid, a valve (11) is arranged in the at least one vent opening (10). When the valve (11) is fully opened, a flow cross-section (d) is clear for the passage of air, and the pipe cross-section (AU) of the diverter distributor (4) and the flow cross-section (d) of the valve (11) are the same as or greater than a minimum cross-section (Dmin), which is calculated from the product of the number of columns in the tube arrangement (25) and the pipe cross-section (AR) of the tubes (Dmin=n AR).
