| 摘要 |
The invention relates to a heat exchanger block (1) including a heat exchanger (4, 41, 42) which is arranged between an inflow surface (2) and an outflow surface (3) so that a transport fluid (5) can be supplied via the inflow surface (2) to a heat exchanging surface (7) of the heat exchanger (4, 41, 42), can be brought into flowing contact with the heat exchanging surface (7) and can be led away from the heat exchanger (4, 41, 42) again via the outflow surface (3) for the exchange of heat between the transport fluid (5) and a heating agent (6) flowing through the heat exchanger (4, 41, 42) in the operating state. In accordance with the invention a perforated coolant lance (8) is provided so that a coolant (9) can be introduced between two heat exchanging surfaces (7) of the heat exchanger (4, 41, 42) via the coolant lance (8)The invention furthermore relates to a method for wetting a heat exchanger block (1).
