Radiators for use in hot water central heating systems.

摘要

A radiator (10) for use in hot water central heating systems is constructed from extruded aluminium alloy sections. One section having a tubular duct (12) extending therethrough and provided with fins (21) is used as the heat exchanger (11) which interconnects the flow header (24) and return header. These headers (24) each incorporate locking flanges (30, 32) which interlock with respective external slots (23) pre-formed in the fins (21) on each side of the heat exchanger (11). Pressure tight fluid connections between the headers (24) and the duct (12) in each heat-exchanger section are made by double-ended chamfered barrel nipples (34).
