Abstract

The utility model pertains to a new heat exchanger in the machinery industry, which integrated the characteristics of both fin and corrugated tubes by taking the defects of traditional similar equipments into consideration. The new heat exchanger is characterized in that a plurality types of fins are arranged on the corrugated tubes. The utility model has the advantages of higher heat exchange efficiency, saving raw materials and small device volume, with a wide application prospect in metallurgy, chemistry industries, etc.

Description

Fin bellows-type heat exchanger

The utility model belongs to a kind of heat-exchange apparatus in the machinery manufacturing industry.

At present, the heat exchanger of domestic and international application can be divided into two major types substantially, i.e. tubular type and board-like; In pipe heat exchanger, be divided into forms such as shell and tube, bushing type, coil pipe type again, fin tube type and bellows-type have appearred again in recent years; Though finned tube and bellows-type heat exchanger have improved the heat exchanger effectiveness of traditional heat exchangers effectively, but still not ideal enough.

The purpose of this utility model is, a kind of fin bellows-type heat exchanger is provided, and on the bellows body of heat exchanger tube 2, various forms of fins is set, and further improves the thermal efficiency of traditional heat exchangers.

Fin bellows-type heat exchanger is to be made of parts such as shell, tube sheet (1), deflection plates (3), it is characterized in that:

A) bellows body of heat exchanger tube (2) is provided with fin (4);

B) fin (4) can by inlay, on the crest that extruding and welding manner are located at bellows body or be arranged on crest and the trough;

C) fin (4) can be the monolithic arrangement, and also shape is provided with helical fin (5) in the shape of a spiral; Fin (4) vertically is provided with at the bellows axis direction, also can multidirectional setting on the bellows body surface.

Good effect of the present utility model is, changes bellows at heat-exchange tube, on the improved basis of heat exchanger effectiveness, integrates the characteristic of finned tube and bellows, improved the thermal efficiency significantly, compares with finned tube to exceed 2～4 times; Raw materials consumption is descended significantly, the equipment overall weight is reduced, volume dwindles greatly, and has the effect of economize on electricity.

Embodiment 1

Trial-production helical form fin bellows-type heat exchanger.Select 70 of spiral integral fins bellowss for use, adopt expansion to connect technology and be fixed on 1 of two tube sheet, tube sheet 1 and the heat exchanger tube 2 that installs assembled in the enclosure, and strict sealing, avoid the mixing of heat exchange two fluids, spill and leakage to leak; Heat exchange area is 15m ²After testing, reach the requirement index really after, be qualified products.Test result shows: suitable fin straight tube bundle heat exchanger 37m ²More than the twice of device heat efficiency.

Embodiment 2

Adopt 360 of transverse fin bellowss, make tubular heat exchanger, in establish deflection plate 3, the crest of bellows and trough all are provided with fin 4, after installation testing is qualified, are used for oil cooler; Fin adopts mosaic technology to install, and can also adopt kinds of processes such as extrusion modling or welding, winding to form the fin bellows; The direction of fin 4 can be taked multiple direction; Increase under the comprehensive function of available heat exchange area and turbulent flow at heat exchanger tube 2, this equipment is compared with former straight pipe type tubular heat exchanger, increases by three times of effective heat transfer areas, has saved a large amount of raw material, and equipment volume dwindles 30%.Result on trial receives praises from customers.
