Abstract

Disclosed is a plate and tube heat exchanging device. A group of plate and tube heat exchanging panels 1 are overlapped and connected, with intervals in between; a plate tube 2 is arranged in parallel inside the plate and tube heat exchanging panel 1; the outward surface of the plate and tube heat exchanging panel 1 is in the shape of equal ripples; the neighbouring plate and tube heat exchanging panels 1 are separated by uniform intervals and are arranged in fluctuation and in transposition; an equivalently folded waveform channel 6 which is vertical to the plate tube 2 is formed between the neighbouring two plate and tube heat exchanging panels 1. The utility model has the advantages of stable integral structure, simple and convenient arrangement, combination and assembling. In addition, the intervals between the plate and tube heat exchanging panels are flexible to be regulated. Free from heat resistance caused by dirt between panels, the utility model has little flowing resistance, thus reinforcing the heat transmission effect. Two heat exchanging flowing bodies cross each other and flow mutual perpendicularly with relatively big heat transmission temperature difference and evidently increased integral stiffness.

The utility model can be simply and conveniently manufactured and installed and can be put into specialized production. With a wide range of application, the utility model can be used in the heat exchanging of cold and hot air, the heat exchange of air and high temperature industrial waste which contains solid particulates, the heating of air by hot water or vapour, the heating of water by high temperature waste gas or flue gas, the heat exchange from water to water (vapour).

Description

The band-tube type heat-exchanger rig

One, technical field: the utility model belongs to a kind of heat-exchange device, especially a kind of band-tube type heat-exchanger rig.

Two, background technology: disclosed heat-exchange device generally can be divided into tubular type and board-like two big classes.Pipe heat exchanger normally is arranged to heat exchanger tube to restrain shape and arranges, cause that heat transfer coefficient is low, volume greatly, deficiency such as easy scaling and maintenance not; Plate type heat exchanger is being widely used aspect the liquid heat exchanges such as water-water in recent years, but aspect gas converting heat, normally used plate-fin and smooth walled still exist between plate thermal resistance big, and heat transfer coefficient is low, problems such as the manufacturing crudy is unsecured, and flow resistance is big, rigidity and intensity are low.In order to improve the raising heat transfer coefficient, increase the heat transfer area of unit volume, reduce technical problems such as flow resistance, various technical scheme has appearred, be 94225613.1 as application number and be called " no fixed tube sheet shell-and-tube heat exchanger ", remain around tubular type and board-like two separate directions and study that technology is also immature, the value deficiency of practical application, above-mentioned technical problem do not solve simultaneously.

Three, summary of the invention: technical problem to be solved in the utility model is to propose a kind of advantage that can have tubular type and board-like two class heat exchangers concurrently, the band-tube type heat-exchanger rig with actual application value.

The measure that overcomes the above problems is one group of plate pipe heat exchanger fin interval overlapping is connected, there is the plate pipe that is arranged in parallel plate pipe heat exchanger fin inside, corrugated such as plate pipe heat exchanger fin two outer surfaces are, the even interval of adjacent panels pipe heat exchanger fin, the dislocation that rises and falls is arranged, form between adjacent second tube sheet heat exchanger fin with the plate tube side to vertical waveform channel.

Overall structure of the present utility model is firm, and the permutation and combination assembling is simple, and plate pipe heat exchanger fin spacing is regulated flexibly, and the scope of application is bigger.Of the present utility modelly be also advantageous in that plate pipe heat exchanger fin two sides are waveform channel, constantly change direction during forced fluid flow, destroy flow boundary layer and make the enhancing of conducting heat, increase length 5%-50% than line flowing channel simultaneously, as setting up fin in plate pipe heat exchanger fin two sides, can heat transfer area be increased considerably, to increase heat output; Because the zero lap heat transfer area does not form dirtiness resistance between plate; Plate pipe cross section of fluid channel in the layout board pipe heat exchanger fin be an ellipse, flows through the fluid of plate pipe heat exchanger fin two sides, the entrance end of process be taper or streamlined, two side runners are the uiform section runner, fluid velocity is constant, and flow resistance is little, and the inlet resistance reduces significantly.Two heat exchanging fluids cross flow one on mutually perpendicular direction, heat transfer temperature difference is bigger; Integral rigidity obviously increases, and can select thin sheet material or foil for use, and material selection is in extensive range, can reduce manufacturing cost significantly, and manufacturing processing is easy, can realize specialized production.
