Thermodynamics > Heat exchangers




The apparatus is for studying heat transfer from hot water to cross flow air such as in automobile radiator.

    The unit consists of an air duct with outlet damper, an automotive radiator, an axial flow fan and a service module. The module provided hot water tank with transfer pump and control and measuring instruments.

    Instruction manual is also supplied.
