Abstract
The utility model relates to a universal pipe-typed heat exchanger for a heat exchange or heat transfer device, which is composed of a seamless elliptical pipe and an outer fin. The inner wall of the seamless elliptical pipe is fully provided with 3-D rib sheets which can be rectangular, T-shaped, needle-shaped, sawtooth-shaped, etc., and the 3-D rib sheets on the inner wall are arranged in a spiral mode. The heat performance of the utility model far overcomes the heat performance of various existing heat exchange pipes through the 3-D rib sheets; the heat transfer coefficient and the heat exchange efficiency are improved, and the heat transfer area is enlarged.
Description
This practicality newly relates to the universal component of a kind of heat exchange or heat-transfer equipment, further relates to a kind of pipe heat exchanger.
Pipe heat exchanger mostly is the single tube structure so far, and heat is implemented in the heat exchanging process between the outer two kinds of working medium of pipe in the pipe according to the tube wall transmission.Yet rate of heat exchange is subjected to the restriction of tube wall shape, area and pipe diameter, the enlarged tube wall area then needs to increase caliber, prolongs tube length or increases number of tubes, the caliber increase can be subjected to the restriction of actual conditionses such as spatial volume, caliber specification, the pipe shaft lengthening can make the intraductal working medium flow resistance strengthen again simultaneously, the operating cost of heat exchanger is increased greatly, and heat exchanger effectiveness is low.
The purpose of this utility model is to provide the three-dimensional internal-rib elliptical fin heat exchanger tube that a kind of heat transfer area is big, heat transfer coefficient is high, it is not under the situation about increasing considerably at heat exchanger volume, make the enhanced heat exchange element with three-dimensional internal-rib elliptical fin, make fluid in pipe or the disturbance increase outside the pipe, heat exchanger effectiveness increases substantially.
The technical solution of the utility model is as follows: it is made up of seamless elliptical tube, outer fin, be covered with three-dimensional rib plate on the inwall of seamless elliptical tube, wherein the three-dimensional rib plate of the inwall of seamless elliptical tube can be shapes such as rectangle, T shape, aciculiform, zigzag, and the three-dimensional rib plate of inwall shape is in the shape of a spiral arranged.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is side of the present utility model and view;
Fig. 2 is that I-I of Fig. 1 is to cutaway view.
As depicted in figs. 1 and 2, the utility model is made up of seamless elliptical tube 2, fin 1, and the elliptical tube inwall has three-dimensional rib plate 3, has flow-disturbing hole 4 on the outer fin 1.Process is to adopt special process to process the spiral three-dimensional fin of shapes such as rectangle, T type, aciculiform, zigzag at round tube inner wall earlier, again this pipe is rolled into elliptical tube 2 by needed major and minor axis size, with sheet metal punching, moulding, outer fin 1, process flow-disturbing hole 4 on the fin 1 outside, the outer fin 1 of moulding is enclosed within on the in type elliptical tube 2, after pickling, alkali cleaning, sends into whole galvanizing in the liquid thermal zinc groove.Its outer fin 1 can be processed into rectangle, zigzag etc., by setting up of inside and outside two-layer heat transfer structure, heat transmission function is strengthened, and heat exchange area enlarges.The oval rectangular fin heat exchanger tube of fluted body spiral wife shown in Fig. 1, as basic structure of the present utility model, the heat exchange tube structure of other shape can change according to this.
The utility model compared with prior art, volume does not increase considerably, but has enlarged heat transfer Area has improved heat transfer coefficient and heat exchanger effectiveness, wherein the three-dimensional inner rib plate of elliptical tube inwall Played decisive role. Operating position proves that thermal performance of the present utility model is considerably beyond existing The various heat exchange pipe fittings that have have improved heat exchanger effectiveness greatly, use very extensive.
