Abstract

The utility model relates to a total isolation plate and plate fin type heat exchanger which belongs to the technical field of plate fin type heat exchangers used in chemical equipment. The utility model has the main technical characteristic that a snake total isolation plate is placed vertically and is folded into two independent inner and outer fluid circulating zones in a rolling mode. The joints of the total isolation plate are connected by two welded seams. Fins are clamped in the snake circle zone of the total isolation plate. The vertical direction of the fins is positioned by shunting orifice plates on the upper end and the lower end and in the middle. The end to end joint of the two parallel partition boards of each circle zone of the total isolation plate is provided with zone dividing plates in a plugging mode. A narrow zone formed by the zone dividing plates is provided with fins in a plugging mode. The utility model has the advantages of decreasing the heat resistance caused by the gaps which are not brazed, making the traditional brazing technology simplified into the assembly technology, being convenient for overhauling and cleaning, simplifying the processing technique, decreasing the production cost of the product and enhancing the production efficiency.

Description

Whole dividing plate plate-fin heat exchanger

One, technical field

The utility model belongs to the plate fin heat-exchanging device that uses in the chemical industry equipment.

Two, background technology

Plate-fin heat exchanger is a kind of heat transfer efficiency height, compact conformation, heat-exchanger rig applied widely.Existing plate-fin heat exchanger structure is formed by stacking by the multilayer insulation plate, and two runners separately circulate cold and hot two kinds of fluid at differing temperatures to carry out exchange heat.Soldering has folded fin as the secondary heating surface between the interlayer of plate-fin heat exchanger, to increase heat exchange area.But the soldering processes in the production process of existing plate-fin heat exchanger are very numerous and diverse, and the process equipment costliness causes manufacturing cost to rise, simultaneously narrow inconvenience cleaning of the heat exchanger channels of heat exchanger and maintenance.

Three, summary of the invention

The purpose of this utility model provides a kind of whole dividing plate plate-fin heat exchanger, and processing technology is simple, has reduced processing cost, convenient maintenance.

The utility model is achieved in that a snakelike whole dividing plate 1 vertically places, and rolls to be converted into inside and outside two independent fluid Circulation Areas, and the interface that will be put in order dividing plate 1 by two weld seams 2 connects; Clamped fin 3 in the snakelike time district of whole dividing plate 1, the vertical direction of fin 3 is by two ends and middle shunting orifice plate 4 location up and down; The end to end place of two parallel baffles, whole dividing plate 1 each time district is fitted with subregion plate 5, is fitted with fin 3 in the narrow district of described subregion plate 5 row; Be close to fin 3 and dosed insulation filler 6; Be fixedly clamped by clamping plate 7 at last, sealed by four jiaos bolt.

On the lower surface of whole dividing plate 1, shrouding 8 is installed successively, cold fluid exit plate 9, hot fluid import plate 10; On the upper surface of whole dividing plate 1, shrouding 8 is installed successively, cold fluid import plate 11, hot fluid exit plate 12.

The fixing shunting orifice plate 4 of fin 3 upper and lower sides is a H shape, and the shunting orifice plate 4 of fin 3 center fixed is plate shaped.

Tap hole diameter on the flow distribution plate 4 is provided with arrangement according to described tap hole and import and export from big to small apart from distance.

Compare with existing plate-fin heat exchanger, the beneficial effects of the utility model are:

1, impressed pressure compresses the fin and the dividing plate of heat exchanger, has avoided numerous and diverse technology of soldering, has reduced the thermal resistance that the gap of non brazing causes;

2, adopt the moulding of snakelike whole dividing plate time processing, make traditional soldering processes be reduced to packaging technology;

3, outer working pressure plate of the present utility model assembles by bolt, conveniently overhauls and cleans;

4, in process of production owing to simplified processing technology, reduced requirement, reduced production cost of products significantly, improved production efficiency process equipment.

Five, the specific embodiment

Snakelike whole dividing plate 1 rolls and is converted into inside and outside two independent fluid Circulation Areas, and cold fluid and hot fluid is divided into two parts circulation duct.As shown in Figure 3, interior road is a hot fluid pipeline 13, and outer course is a cold fluid pipeline 14, and fin 3 is as the secondary heating surface, to strengthen thermolysis.The utility model upper/lower terminal is respectively equipped with two groups of cold fluid and hot fluid pipe turnover oralias, the multilayer flow distribution plate is arranged, to regulate each small flow channels flow rate of fluid and flow in the passage.Outer pressure clamping plate 7 pressurizations are to guarantee that fin 3 combines closely with whole dividing plate 1.

H type flow distribution plate 4 is a profile among Fig. 4.

In the present embodiment, on the lower surface of whole dividing plate 1: 8 one groups of shroudings are installed successively, 9 two of cold fluid exit plate, 10 1 of hot fluid import plates; The upper end of corresponding whole dividing plate 1 makes progress: 8 one groups of shroudings are installed successively, 11 two of cold fluid import plates, 12 1 of hot fluid exit plate.
