Lord Fin Tube--Fin type heat radiator

fin type heat radiator

The fin type heat radiator is adopted to achieve the purpose of heat transfer enhancement by adding fins on a common base tube. Base tube can be used steel pipe; stainless steel pipe; brass, etc.. The fin can also use steel strip; stainless steel, copper, aluminum etc..
Fin type radiator in the form of the fin structure can be divided into the winding type; series chip; welding chip; rolled piece.
At present, the most widely used is the steel aluminum composite fin tube, which uses the steel pipes pressure resistance and high efficiency thermal conductivity of aluminum, in a special machine tool on the composite. The thermal contact resistance is almost zero at 210 centigrade.
The steel aluminum composite pipe has the advantage of other kinds of fin and tube heat sink.
1 the thermal performance of the fin type heat sink, the higher the heat transfer coefficient K value, the better the cooling performance. To improve the heat dissipating capacity of the radiator, the fin type radiator heat transfer coefficient is increased and can be used to increase the radiating area of the outer wall of the improved finned radiator in the surrounding air flow velocity and increase the radiator radiates strength way.
2 economic aspects of the request, the fin type radiator heat transfer to the room of the unit of heat required for the less metal consumption, the lower the cost, the better the economy. The metal heat intensity of the fin type radiator is a sign of the economic performance of the radiator. Metal thermal intensity refers to the radiator heat medium average temperature and indoor air temperature difference of 1 degrees. From the quality of per kilogram per unit time of heat radiator. This index can be used as an indicator to measure the economic performance of the same material radiator. For a variety of different materials of the fin type radiator, the economic evaluation standard is appropriate to the radiator unit heat dissipation cost (yuan /w) to measure.
3, installation, use and process of requirements finned radiator should have certain mechanical strength and bearing capacity; structure should be convenient combination for the heat dissipation area, structure size small, accounting for less space and room space and fin type radiator production process should meet the requirements of mass production.
4. The health and appearance, the appearance of smooth, non fouling and easy to clean, fin type radiator design should not affect room perception.
5 service life requirements, fin type radiator should not be easy to be corroded and damaged, long service life.
