HEAT EXCHANGER AND BOILER COMPRISING THE HEAT EXCHANGER

摘要

A heat exchanger for exchanging heat between a first and a second medium comprising a casing having a compartment enclosing a plurality of substantially parallel tubes (24) and an inlet and an outlet arranged such that the first medium is constrained to flow from inlet to outlet in a flow direction (R) substantially parallel to the tubes, a plurality of elongate surface enlarging elements (28) for the improved exchange of heat each having a first end attached to one of the tubes and extending obliquely and generally transverse relative to the flow direction to a second unattached end, the second unattached end being located upstream of said first end relative to the flow direction, the heat exchanger further comprising at least one perforated sound suppressing plate (52) mounted between the tubes such that the compartment is subdivided into two or more sub-compartments.
