Description

Finned heat exchanger is led directly to outside a kind of vertical runner

Technical field

The utility model is related to technical field of heat exchange equipment, and finned heat exchanger is led directly to outside more particularly to a kind of vertical runner.

Background technology

Tubular heat exchanger (tubular exchanger) is that one kind most widely used in current chemical industry and Alcohol Production is changed Hot device.It is mainly made up of housing, tube sheet, heat exchanger tube, end socket, hydraulic barrier etc..Required material, can be respectively adopted common carbon Steel, red copper or stainless steel make.When being exchanged heat, a kind of fluid is entered by the connecting piece of end socket, in pipe flowing, from envelope The outlet outflow of the head other end, this is referred to as tube side；Separately-kind of fluid is entered by the adapter of housing, from another adapter on housing Place's outflow, this is referred to as shell side tubular heat exchanger.

But current tubular heat exchanger, heat exchanger tube energy consumption is too high, and weight is too big, and is easily produced during heat exchange Life and death angle, is a kind of very uneconomical and backward technology.

Utility model content

The utility model, which is provided, leads directly to finned heat exchanger outside a kind of vertical runner, solve existing tubular heat exchanger energy consumption High, weight is too big, the problem of be also easy to produce dead angle.

In order to solve the above technical problems, the technical solution of the utility model is：

Led directly to outside a kind of vertical runner outside finned heat exchanger, including base tube, the base tube and be arranged with aluminum pipe, the aluminum pipe peripheral hardware Outer fin is equipped with, the outer fin is made up of the heat-sink unit longitudinally led directly to along the base tube, the cross section of the heat-sink unit Take the shape of the letter U, the outer fin is connected with base tube sintering.

Wherein it is preferred to, the cross section of the heat-sink unit includes arc, and the arc two ends are connected with straight line Section.

Wherein it is preferred to, corresponding 180 ° of the central angle of the arc, the diameter of the arc and the straightway Length ratio is 1:1~1.5.

Wherein it is preferred to, the inwall of the base tube is provided with helicla flute.

Wherein it is preferred to, the helicla flute is multi-head spiral groove.

Wherein it is preferred to, it is respectively arranged with zinc coat on the surface of the base tube and the outer fin.

The beneficial effects of the utility model：

1. the utility model China and foreign countries fin is connected with base tube sintering, integral type leads directly to outer fin heat exchange pipe than conventional fins pipe With bigger specific surface area, therefore heat transfer rate is faster, and heat transfer efficiency is higher, can be widely used in the energy, chemical industry, refrigeration etc. Field.

2. the helicla flute in the utility model base tube, produces disturbance to the fluid media (medium) of the flowing in base tube, improves heat exchange The heat exchange efficiency of pipe.

3. the utility model is bimetallic nickel plating, strong with surface texture power, anti-impact brushing force is big；Coating is extremely uniform, table Surface hardness is high, corrosion-resistant；Surface is less scaling, improves the advantages of service life improves 3 times than not nickel plating service life.

In figure, 1. base tubes, 2. outer fins, 2-1. arcs, 2-2. straightways, 3. zinc coats

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The all other embodiment obtained, belongs to the scope of the utility model protection.

As depicted in figs. 1 and 2, the present embodiment provides and finned heat exchanger is led directly to outside a kind of vertical runner, including base tube, outside base tube It is arranged with outside aluminum pipe, aluminum pipe and is provided with outer fin, outer fin is made up of the heat-sink unit longitudinally led directly to along base tube, heat-sink unit U-shaped profile, outer fin is connected with base tube sintering.The outer fin heat exchange pipe of integral type has bigger ratio table than conventional fins pipe Area, therefore heat transfer rate is faster, heat transfer efficiency is higher, can be widely used in the fields such as the energy, chemical industry, refrigeration.In addition, outer wing Piece is connected with base tube sintering, in the absence of thermal contact resistance, further increases heat transfer efficiency.

Wherein, the cross section of heat-sink unit includes arc, and arc two ends are connected with straightway.The corresponding circle of arc 180 ° of heart angle, the diameter of arc and the length ratio of straightway are 1:1.2.In the utility model, the diameter of arc with it is straight The length ratio of line segment does not limit to this, according to the difference of heat transfer medium, and the length ratio of the two is 1:1~1.5.

Wherein, the inwall of base tube is provided with helicla flute, produces disturbance to the fluid media (medium) of the flowing in base tube, improves heat exchange The heat exchange efficiency of pipe, also, in order to which the helicla flute further improved in the disturbance of fluid medium generation, the present embodiment is bull Helicla flute (not shown).

Wherein, it is respectively arranged with zinc coat on the surface of base tube and outer fin.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
