Abstract

The invention provides internal and external finned tubes with an efficient heat exchanging function, an efficient heat exchanger and a manufacturing method for the efficient heat exchanger. The problem that an external-fin type heat exchanger is not high enough in heat exchanging efficiency can be mainly solved. In order to further improve the heat exchanging efficiency of finned tubes, firstly, internal fins are added to a heat exchange pipeline, then heat exchangers with internal and external fins are overlapped to be made into a multi-stage circulation tube bank box recoverer or a heat pipe type waste heat recoverer which is used in cooperation with an industrial clothes dryer and an object dryer, and therefore the intended purposes of high efficiency and energy conservation are achieved. The efficient heat exchanger is quite suitable for being selected, produced, used and popularized by special production factories and specialized households.

Description

The internal and external finned tubes of high efficient heat exchanging and high-performance heat exchanger and manufacture method thereof

Technical field: a kind of internal and external finned tubes of high efficient heat exchanging and high-performance heat exchanger and make making method, belongs to pipeline and method field of manufacturing.

Background technology: due to the needs of energy-saving and emission-reduction, scientific worker has invented calandria gas one gas waste-heat recoverer, this waste-heat recoverer have employed the method being socketed outer fin outward at pipeline and has made than the outer fin comb afterheat heat exchanger with high several times of the waste-heat recoverer heat exchange efficiency not having the naked body pipeline of fin to make, but along with the requirement of environmental protection and energy saving and the needs of social development, especially the heat exchange efficiency of heat exchanger has proposed higher standard-required, therefore in the urgent need to researching and developing a kind of new pipeline for the manufacture of more high-performance heat exchanger.Object of the present invention is for realizing high effective heat transfering tube with inner fins road that preceding aim designs and and efficient discharge heat exchange of heat pipe and manufacture method thereof.

Summary of the invention: in order to realize aforementioned object, imagination of the present invention is: adopt copper sheet or aluminum slice that heat exchange efficiency is higher, take first weld on thin plate two sides or be molded into the thin plate that there is fin on two sides, then on demand bore cut close size be rolled into pipe welding make inside and outside have the inside and outside fin pipeline of fin, except two sides welding fin and with mould water cast out two sides have fin sheet reel be welded into inside and outside have the finned tube of fin except, the third method adopts collapsed corrugations plate, the mode that reel docks has the inside and outside corrugated finned pipe of convex-concave corrugated fin inside and outside making.Manufactured by three kinds of methods, all to have gas contact heat-exchanging area large for internal and external finned tubes out, heat transfer is fast, the feature that heat exchange efficiency is high, thus can be used for manufacturing the better efficient waste heat recover of heat transfer effect, referred to as high-performance heat exchanger or be called efficient level heat exchanger, its concrete manufacture method also has two kinds of modes, can make calandria and heat pipe-type two kinds of high-performance heat exchangers; Be specifically designed to and reclaim the various industry dryer waste heat of discharging and support the use.Realize the expection object improving Synergistic and energy-saving reduction of discharging.
