Description
Technical field
The utility model is related to a kind of heat exchanger, especially overlength high efficient fin type heat exchanger.
Background technology
, more than 3 meters, the heat exchanger of this overlength is at present all using finned for the heat exchanger length that some equipment are needed to use
Heat exchanger, due to heat exchanger surface complex structure, length is more long, does not install the strong point, is easy in the operation of big flow operating mode
Vibration is produced, causes fatigue crack, cause the heat exchanger lost of life, scrapped ahead of time.Current this overlength heat exchanger is usually used
Life-span only one year, can only more renew after damage, and maintenance cost is very high.
Due to the influence of the factors such as mould, technique and equipment, fin generally can not be made thin big, in overlength heat exchanger,
Fin is typically multiple laid out in parallel, it is impossible to improve the bulk strength of overlength heat exchanger.For reduces cost, existing fin is a lot
Using aluminum fin-stock, aluminum fin-stock is softer, makes that the intensity of overlength heat exchanger is worse, and service life is shorter, while heat transfer effect is poor.
Utility model content
To solve the above problems, a kind of good effect of heat exchange of the utility model offer, intensity are high, long service life overlength is high
Finned heat exchanger is imitated, concrete technical scheme is：
Overlength high efficient fin type heat exchanger, including fin, heat exchanger tube and reinforcing plate；The heat exchanger tube is provided with many, heat exchange
Pipe is equidistantly interspersed, and one end of heat exchanger tube is provided with large tubesheet, and the other end is provided with small tube sheet, the heat exchanger tube and large tubesheet and
Small tube sheet is fixedly connected；The fin is provided with multiple fin pores corresponding with heat exchanger tube, and the heat exchanger tube is inserted in fin
In pore, the fin is provided with multiple rows of, is distributed along the axial direction of heat exchanger tube, and is equidistantly enclosed within heat exchanger tube, often arranges many two
Individual fin and column distribution；The reinforcing plate is provided with multiple reinforcing plate pores corresponding with heat exchanger tube, and the heat exchanger tube is inserted in
In reinforcing plate pore, the reinforcing plate is no less than one, and is equidistantly fixed between large tubesheet and small tube sheet.
The fin is copper fin.
The heat exchanger tube is stainless steel heat exchange tube.
The thermal conductivity factor of copper is far above aluminium, and strength ratio aluminium is high, therefore improves bulk strength and the radiating of heat exchanger
Effect.
The bulk strength of heat exchanger is improve using stainless steel heat exchange tube.
Reinforcing plate is tight fit with stainless steel, is realized by way of drawing and rising.Reinforcing plate make many stainless steel heat exchange tubes with
Reinforcing plate forms overall structure, improves intensity, solves vibration problem, improves service life.The quantity of reinforcing plate can root
Set according to the length of heat exchanger, no less than one.During using a reinforcing plate, reinforcing plate is located at the axial interposition of heat exchanger tube
Put.Using more than two reinforcing plates, equidistantly install.
Although improve the cost of overlength heat exchanger using copper fin and stainless steel heat exchange tube, greatly extending makes
With the life-span, it is not necessary to which annual more switching heat-exchanger, maintenance cost is low, and comprehensive use cost is low.
The utility model has the advantages that compared with prior art：
The utility model provide overlength high efficient fin type heat exchanger structure it is simple, intensity is high, without friction, heat exchange efficiency
Height, long service life, maintenance cost are low.
