The industrial finned tube radiator is the main equipment in the heat exchange device such as cooling air with refrigerant, heating air with heat medium, or recovering air waste heat with cold water.
The air can be heated by feeding high temperature water, steam or high temperature heat transfer oil, and the air can be cooled by feeding salt water or low temperature water.
Industrial finned tube radiator
The heat dissipation pipe is composed of a heat dissipation pipe bundle, and the heat dissipation pipe is composed of a base pipe and a fin.
The quality of the heat pipe determines the heat exchange effect, the arrangement of the heat pipe affects the air resistance, and the installation method of the heat pipe determines the ability to withstand temperature differences.
Commonly used industrial finned tube radiator installation methods: frame fixed type, frame support type (GL type, U type).
Industrial finned tube
Among them, the frame fixed type, the heat pipe is directly welded to the frame box, the structure is simple, generally used for heat or refrigerant below 180 ℃; the frame support type, the heat pipe passes through the frame porous plate, and is welded with the connecting pipe (or elbow) , generally used for heating medium above 180 ℃.
Commonly used finned tube heat pipe types: steel heat pipe, steel-aluminum composite heat pipe, copper heat pipe, copper-aluminum composite heat pipe, stainless steel heat pipe.
Finned tube radiator
Main technical parameters of industrial finned tube radiator: heat dissipation area, net ventilation cross-sectional area, heat transfer coefficient.
Among them, the heat dissipation area affects the heat dissipation and is also the main cost parameter of the radiator; the ventilation net cross-sectional area affects the ventilation resistance; the heat transfer coefficient affects the heat transfer effect.
Industrial finned tube radiator selection parameters: heat medium (steam, hot water), hot air, materials, heat transfer oil, solutions of other media.
Among them: steam (pressure, temperature), hot water (inlet water temperature, outlet water temperature, flow rate), hot air (flow rate, inlet air temperature, humidity (water content), outlet air temperature, air resistance), material (heat consumption, evaporation water), heat transfer oil (inlet temperature, flow).
Thermal insulation industrial finned tube radiator selection parameters: heat medium, space, area, thermal insulation.
Among them: steam, hot water (inlet water temperature, outlet water temperature, flow rate), space (length, width, height).
