A heat exchanger including the multiplicity of elongate laterally spaced parallel tubes, each of which is formed with circumferentially spaced longitudinally extending radially outwardly projecting lobes which are semi-circular in cross-section and circumferentially spaced longitudinally extending radially outwardly opening intermediate grooves which are semi-circular in cross-section and wherein related lobes and grooves of adjacent tubes are interengated with their opposing semi-circular surfaces in uniform spaced relationship from each other whereby a labyrinth of passages of substantially uniform cross-section, through which a fluid medium can flow, occur about and between all adjacent related tubes whereby more uniform lateral flow of a fluid medium about and between adjacent tubes is attainable.
