Abstract

In the field of heat exchangers for air conditioning systems there is a need for an improved heat exchanger which provides improved efficiency in terms of overall packaging and performance.
A heat exchanger (70; 90; 100; 140), for use in an air conditioning system of a building, comprises an elongate fluid conduit (32) which has first and second elongate heat exchange fins (34, 36) extending laterally therefrom. Opposed faces (38, 40) of the first and second fins (34, 36) define an acute angle therebetween. The fluid conduit (32) defines a discrete conduit body (42), the first fin (34) defines a first fin body (44), and the second fin (36) defines a second fin body (46). The conduit body (42) is thermally coupled to at least one of the first and second fin bodies (44, 46) by a discrete heat exchange member (72).
