F28D1/022 - CPC Classification

Classification description:

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 with heat-exchange conduits immersed in the body of fluid; Heat exchangers immersed in a large body of liquid for immersion in a natural body of water, e.g. marine radiators
