HEAT EXCHANGER

摘要

A heat exchanger unit (110) for a heating system comprises a manifold (111) having a fluid inlet (112) for connection to a fluid conduit of the heating system and a fluid outlet (113), the manifold defining a flow path (140) for fluid between the fluid inlet and the fluid outlet. The manifold has an outer wall with a plurality of apertures (119). A plurality of heat pipes (120) is sealingly mounted in a respective aperture (119) of the wall of the manifold (111). Each heat pipe (120) comprises a body having an outer sleeve. A major part of the heat pipe (120) extends outwardly from the manifold (111) and one end of the heat pipe is positioned in the flow path of the manifold, such that there is direct contact between the outer sleeve of the heat pipe (120) and fluid in the flow path.
