Abstract

The utility model relates to an arc-line ring shaped corrugated pipe type heat exchanger. The arc-line ring shaped corrugated pipe type heat exchanger is extensively used for the fluid heat exchanging device of the industries of heating power, electric power, petroleum, a chemical industry, a light industry, foodstuffs, living hot water, etc. The arc-line ring shaped corrugated pipe type heat exchanger comprises pipe plates, corrugated pipes, a shell body, baffle plates, and a supporting seat. The pipe plates are arranged on two ends of the shell body. A plurality of corrugated pipes are all arranged inside the shell body, and two ends of the corrugated pipes are arranged on the pipe plates. The baffle plates are arranged inside the shell body in a top and bottom staggered mode. A fluid channel inside the shell body is divided to form an S-shaped trending fluid channel. The supporting seat is arranged on the lower surface of the shell body. The utility model has the advantages of high heat transfer efficiency, low running consumption, non-easy fouling, good interchanging ability, small size, low cost, reliable operation, etc.

Description

Camber line annular ripple tubular type heat exchanger

Technical field: the utility model relates to a kind of heat-exchanger rig, a kind of specifically heat-exchange device---camber line annular ripple tubular type heat exchanger that is widely used in industry fluids such as heating power, electric power, oil, chemical industry, light industry, food and domestic hot-water.

Background technology: at present, heat transmission equipment commonly used is based on common tubular heat exchanger, and its main heat exchange element is common hollow pipe, heat-resisting, withstand voltage, good reliability, but heat transfer efficiency is low, operating cost height, serious waste heating power and power source.

In order to solve the above problems, people adopt bellows to replace common hollow pipe, have reached the purpose that improves heat transfer efficiency, but heat exchanger applied still influences its reliability and heat transfer efficiency owing to structure is reasonable inadequately in the market.

Summary of the invention: the purpose of this utility model is to provide a kind of simple and reasonable, good reliability, the camber line annular ripple tubular type heat exchanger that heat transfer efficiency is high.

The purpose of this utility model is to realize like this, this heat exchanger comprises tube sheet, bellows, housing, deflection plate, bearing, its tube sheet is set at the two ends of housing, the equal portion of a plurality of bellowss is arranged in the housing, two ends are arranged on the tube sheet, in housing, be staggeredly equipped with deflection plate up and down, the fluid passage that forms the serpentine trend separated in the fluid passage of enclosure interior, bearing be arranged on housing below.

The two ends up and down of described housing have the outlet of hot fluid import and hot fluid respectively, and two ends, the left and right sides have respectively and are heated fluid issuing and are heated fluid inlet.

The prolongation and the tube sheet of described bellows directly weld together.

Described hot fluid I is entered in the housing by the hot fluid import above the housing and is " S " trend through deflection plate and exports out from hot fluid; Being heated fluid II enters in bellows to come out from being heated fluid issuing by being heated fluid inlet; Flowing mutually of two kinds of fluids reached the purpose of heat exchange.

Described bellows is the heat exchange element of heat exchanger, and it is pressed into convex camber line shape hoop ripple outward, and external diameter is the standard pipe external diameter, ripple spacing t, and the size of convex height b is determined by the physical parameter of fluid.

The utlity model has following advantage:

1, heat transfer efficiency height: the variation of hollow tube heat exchanger element internal diameter and external diameter, the direction of fluid is constantly changed, the turbulent flow ability improves, and makes the more common tubulation of its heat exchange efficiency improve 2-5 doubly.

2, operation consumes low: can realize fluid high heat transfer flow regime under the low flow velocity, make the operation power consumption reduce more than one times.

3, less scaling: fluid constantly changes flow direction, washes away tube wall, prevents the formation of dirty body, and ripple increases pipe elasticity, has self-cleaning ability.

4, interchangeability is good: maximum outside diameter is identical with standard pipe, has good interchangeability.

5, volume is little, cost is low: high-performance conduct heat make shell carry volume only for common tubular heat exchanger half or littler, manufacturing cost decline 30%-50%.

6, reliable: pipe end and tube sheet welding section are the prolongation of heat exchanger tube main body, replace the welded pipe header structure, and making heat exchange element is first-class wall thickness integral body, avoid vibration frequency different and the joint weld is destroyed.

Fig. 2 is the utility model bellows part-structure schematic diagram.

The specific embodiment:

This heat exchanger comprises tube sheet 2, bellows 4, housing 5, deflection plate 6, bearing 9, its tube sheet 2 is set at the two ends of housing 5, a plurality of bellows 4 equal portions are arranged on that two ends are connected with tube sheet 2 in the housing 5, in housing 5, be staggeredly equipped with deflection plate 6 up and down, the fluid passage that forms the serpentine trend is separated in the fluid passage of enclosure interior, bearing 9 be arranged on housing 5 below.

The two ends up and down of described housing 5 have hot fluid import 3 and hot fluid outlet 8 respectively, and two ends, the left and right sides have respectively and are heated fluid issuing 1 and are heated fluid inlet 7.

The prolongation 10 and the tube sheet 2 of described bellows 4 directly weld together.

Described bellows 4 is the heat exchange element of heat exchanger, and it is pressed into convex camber line shape hoop ripple outward, and external diameter is the standard pipe external diameter, ripple spacing t, and the size of convex height b is determined by the physical parameter of fluid.

Described hot fluid I enters process deflection plate 6 in the housing 5 by the hot fluid import 3 above the housing 5, and the flow direction of hot fluid I is " S " trend, comes out from hot fluid outlet 8; Being heated fluid II enters in bellows 4 to come out from being heated fluid issuing 1 by being heated fluid inlet 7; Flowing mutually of two kinds of fluids reached the purpose of heat exchange.
