Air to Water Heat Exchanger with Fan The
air radiator is the main device of the heat exchangers using a cold
medium and a heat medium for air cooling or heating. It can heat
air if fed with high-temperature water, steam or heat transfer oil,
or cool air if fed with saltwater, so it is extensively used in the
warm-air heating, air-conditioning, cooling, condensing,
dehumidifying and drying in fields such as light industry,
architecture, chemical industry, machinery, textile, printing and
dyeing, electronics, food, pharmaceutical industry, metallurgy,
wood, plastics, rubber, etc.SRZ air heater can be used for the air
heating purpose of both steam systems and hot water systems. It is
mainly used for the air heating of warm-air heating system,
air-conditioning systems, and drying devices. As the main part of
air heating devices, it is widely used in the heating and
ventilation systems of the large buildings of present industrial
and mining enterprises.The heat medium of the air radiator may be
steam, hot water or heat transfer oil. The operating pressure of
steam is 0.2 MPa to 1.6MPa; the temperatures of hot water and heat
transfer oil are about 70ºC to 150ºC and 160ºC to 300ºC
respectively.Selection principles, steel standards, thermal
treatment states and permissible stress values of the materials of
the pressure parts should be subject to requirements of the GB 150.
The pressure parts used in inflammable, fatal or toxic operating
environments should be made of cast iron.The common parent tube
materials include carbon steel Q235B, 20#, 304, 316, copper tube,
etc.The common fin materials include carbon steel, 304, 316,
aluminum, etc.See Table 2 for the common materials of other
parts.Table 2 Materials Parts of the air
