Abstract
The present invention discloses a kind of inner-outer fin tube and fin tube group, and it is formed from inner core, outer tube, fin A and fin B. It is characterized by that it in the interior of outer tube the inner core is set, between inner core and outer tube the fin A is mounted and between outer tube and outer wall the fin B is mounted. Said invented fin tube and fin tube group are equioped with high-efficiency compact secondary heat-conducting surface respectively on inner wall and outer wall of heat-exchange tube, and can be used in the heat exchanger in which the heat emission coefficients of its two side heat exchange fluids are smaller and/or approximate. The structure of said heat exchange is more reasonable, compact and high in heat-conductive efficiency, specially it is applicable to gas-gas medium heat exchange.
Description
Technical field
The present invention discloses a kind of internal and external finned tubes and fin tube bundle, is specially adapted to gas-gas-heat exchanger.
Background technology
For improving the heat transfer coefficient of heat exchanger, increase the heat transfer area of heat exchanger, reduce heat exchanger volume and weight, be everlasting and increase fin (or claiming fin) on heat exchanger tube outer wall or the inwall, the finned tube that is used for heat exchanger at present, can be divided into two classes substantially: a class is an external finned tube, and this class finned tube has pipe with wound fin, nest plate pipe and whole rolled fin pipe etc.; Another kind of is internally finned tube, this class finned tube is to increase fin on the heat exchanger tube inwall, as on the heat exchanger tube inwall, drawing out rib longitudinally, or in heat exchanger tube, pack into and have the inner core of external fin, in addition, also have a kind of internally finned tube, it is provided with interior pipe in outer tube, between outer tube and the interior pipe fin is arranged, interior effective plug is shut.Above-mentioned finned tube is applicable to that mainly both sides heat exchanging fluid exothermic coefficient differs bigger occasion, as the heat exchange between gas-liquid, is not suitable for the less and/or close occasion of both sides heat exchanging fluid exothermic coefficient, as the heat exchange between gas-gas.
The purpose of this invention is to provide a kind of internal and external finned tubes and fin tube bundle that uses in the less and/or close heat exchanger of both sides heat exchanging fluid exothermic coefficient that be applicable to, this finned tube and finned tube family are specially adapted to carry out between gas-gas the heat exchanger of heat exchange.
Summary of the invention
Internal and external finned tubes provided by the invention and fin tube bundle are made up of inner core 1, outer tube 2, fin 3, fin 4, it is characterized in that, are provided with inner core 1 in the outer tube 2, between inner core 1 and the outer tube 2 fin 3 are arranged, and on outer tube 2 outer walls fin 4 are arranged.
Inner core 1 of the present invention can be light pipe, pole, also can be to have totally to be the integrally finned tubes of vertical external fin or rod, and when inner core 1 was pipe, endoporus can be shut; Outer tube 2 can be a light pipe, also can be the integrally finned tubes that has external fin or vertical internal-rib; Fin 3 can be the continuous and/or interrupted folded fin of plate system, it also can be the external fin of inner core 1, the internal-rib of outer tube 2, when fin 3 is folded fin, the shape of folded fin can be straight shape, straight punching shape, zigzag, corrugated, shutter shape, sheet bar shaped, also can be the fin of many other shapes of obtaining of their difform combinations or conversion; Fin 4 can be that the bar shaped of plate system is around sheet, the external fin of outer tube 2 or plate shaped fin, plate shaped fin has the plate shaped fin of plate shaped fin of pore solitary and multitube hole, fluting or difform protuberance can be arranged on the plate shaped fin, ripple etc., to promote flow disturbance, breakable layer laminar sublayer, enhanced heat exchange.When the plate shaped fin 4 of pore solitary is arranged on outer tube 2 outer walls, constitute internal and external finned tubes of the present invention.When the plate shaped fin 4 in multitube hole is arranged on some outer tube 2 outer walls, constitute the inside and outside fin tube bundle.
Internal and external finned tubes of the present invention and fin tube bundle, owing on the inside and outside wall of heat exchanger tube, all be furnished with efficient, compact secondary heating surface, be used for the less and/or close heat exchanger of two side liquid exothermic coefficients, the heat exchanger structure design is reasonable more, compact, heat transfer efficiency is higher, can significantly reduce heat exchanger volume and weight, save raw materials consumption.
