In a sectional radiator for domestic use or for use in a vehicle, in which each section comprises complementary half-sections 1, 2 joined together to form tubular passages extending between two fluid-collecting chambers each in the form of a collar 3, 3a, the collar has a projecting flange 9a which engages in the collar of a neighbouring section and which accommodates a spacing washer 10, a perforated reinforcing ring 11 being disposed within each collar and the assembly of sections being held together by threaded rods 12 extending through the collars between end clamping members 13, 16 one at least of which serves to conduct fluid to or from the radiator. Secondary heat exchange surfaces in the form of corrugated metal strips 17 may be secured between adjacent sections and may be shaped at their crests to correspond with the external contour of the sections (Fig. 9, not shown). The rings 11 and bolts 12 may be made of a reinforced synthetic plastic material and the heat exchange elements may be dipped into a suitable adhesive which provides also a protective coating. A radiator section may contain tubes 8a, 8b, 8c of differing cross-sectional area (Fig. 12). Fig. 11 shows a vehicle radiator in which the top header of the tube assembly is joined at both ends to a header box 18 of synthetic plastic material, the radiator having side plates 20 each provided with a mounting flange 21.
