F28D 1 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, in which the other heat-exchange medium is a large body of fluid, e.g. domestic or motor car radiators (15,886)
F28D 11 - Heat-exchange apparatus employing moving conduits (827)
F28D 13 - Heat-exchange apparatus using a fluidised bed (566)
F28D 15 - Heat-exchange apparatus with the intermediate heat-transfer medium in closed tubes passing into or through the conduit walls (13,807)
F28D 17 - Regenerative heat-exchange apparatus in which a stationary intermediate heat-transfer medium or body is contacted successively by each heat-exchange medium, e.g. using granular particles (1,231)
F28D 19 - Regenerative heat-exchange apparatus in which the intermediate heat-transfer medium or body is moved successively into contact with each heat-exchange medium (1,599)

F28D 21 - Heat-exchange apparatus not covered by any of the groups (2,512)
F28D 3 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, in which the other heat-exchange medium flows in a continuous film, or trickles freely, over the conduits (934)
F28D 5 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, using the cooling effect of natural or forced evaporation (2,036)
F28D 7 - Heat-exchange apparatus having stationary tubular conduit assemblies for both heat-exchange media, the media being in contact with different sides of a conduit wall (15,499)
F28D 9 - Heat-exchange apparatus having stationary plate-like or laminated conduit assemblies for both heat-exchange media, the media being in contact with different sides of a conduit wall (9,577)
