Product Description
Finned radiator is one of the most widely used heat exchangers in gas and liquid heat exchangers. It is through the addition of fins in the general base pipe to achieve the purpose of enhanced heat transfer. The base pipe can be used steel pipe; stainless steel pipe; brass and so on. Fin strip can also be used; stainless steel, copper, aluminum and so on.
Finned Heat Exchanger is mainly used for drying air heating system is the main device in the hot air device, the radiator heat medium can be used steam or hot water, can also be used in heat transfer oil, steam pressure is generally not more than 0.8Mpa , And the temperature of the hot air is 150 ° C or lower.
Selection of Tube Spacing and Slice Distance
Usually, the fin-Tube Heat Exchanger spacing and height are mainly affected by the wing-to-wing ratio, fineness ratio and the tube inside and outside the media membrane heat transfer coefficient has a great relationship. If the tube inside and outside the membrane heat transfer coefficient of difference, should select the wing than the relatively large fin tubes, such as steam heating the air. When there is phase change in one side of the medium, the difference in heat transfer coefficient will be larger, such as the exchange of hot and cold air, when the hot air below the dew point, you can use finned tube heat exchanger. In the absence of phase change of air and air heat transfer, or water and water heat exchange, usually more suitable for bare pipe. Of course, you can also use low-fin tube, because at this time belongs to the weak heat transfer coefficient, to strengthen one side of which have some effect. However, the role of the wing is too large is not obvious, the best internal and external contact area of the tube at the same time to strengthen, you can use threaded pipe or groove tube.
Fins from the main consideration is fouling, dust, easy to clean and other factors, at the same time to be strictly in line with equipment requirements such as pressure drop. Arrangement, the pipe and the distance between the tube is not easy to too large, generally> 1mm or more for the cloth can be. In the heat transfer process, the air flow through the finned tube heat exchanger, the main is the two sides of the fin surface to participate in heat transfer. The middle part of the two fin tubes has only a small amount of radiation heat transfer, the heat transfer effect is not obvious. This part because no fin, no resistance, easy to penetrate the air. During the process of air heating, the cold air without heat exchange will neutralize the heated air passing through from the middle of the fin, but reduce the effect of heat exchange. Compared with the foreign finned tube heat exchanger, The spacing is only 0.5mm larger than the outer diameter of the fin, showing the importance of the tube spacing when arranging the finned tubes.
