Description

Fat pipe cellular board welded type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, a kind of plate type heat exchanger.

Background technology

Plate type heat exchanger is from coming into operation in industry first, in the history in existing more than 50 year of China.Particularly since nineteen sixty-five Lan Shi factory succeeds in developing first homemade plate type heat exchanger-BP05 template formula heat exchanger, the application at home of the technology of plate type heat exchanger more and more widely, enter after the eighties, the technology of plate type heat exchanger has obtained significant progress at home.The plate type heat exchanger particular structure makes it have very high heat transfer coefficient, is generally 4500-6500W/m ²K; have simultaneously compact conformation again, take up an area of characteristics such as the space is little, dismounting is easy to maintenance; the material of its a high proportion of part universality, optional majority kind, characteristics such as accomplish scale production easily; the manufacturing cost of plate type heat exchanger is reduced significantly; have vast market; a lot of fields such as purposes has spreaded all over food, brewages, machinery, metallurgy, chemical industry, oil, electric power, boats and ships, nuclear industry, weaving, and become leading heat transmission equipment in the concentrated supply of heating in the city engineering.

For traditional detachable plate type heat exchanger, owing to there be the rubber gasket defective of inefficacy and the restriction of structure easily at high temperature, be difficult to be competent in industry production technologies such as sugaring, papermaking, metallurgy, alcohol, chemical industry, handle and contain a large amount of solid particles and fibre suspension, and the heating of thick fluid or cooling.At present domesticly generally select spiral-plate heat exchanger or shell-and-tube heat exchanger for use in these occasions, but the heat exchange efficiency of these two kinds of heat exchangers is low, it only is 150m that the maximum of spiral-plate heat exchanger is made area ², the very difficult needs that adapt to industrial large-sizedization productions such as metallurgy, alcohol; Though shell-and-tube heat exchanger is made area can be very big, area is crossed conference and is brought weight of equipment very big, and the occupation of land space is big, increases difficulty, maintenance difficult etc. for lifting, transportation.

The content of utility model

The purpose of this utility model be for provide a kind of compact conformation, heat exchange efficiency height, high temperature resistant, clean fat pipe welded type plate type heat exchanger easily.

The purpose of this utility model can realize by following measure:

A kind of fat pipe cellular board welded type heat exchanger comprises heat exchange core body, pressing plate, boardside shell, pipeside shell, flange, blind plate and pressing plate; Described heat exchange core body is a nest shape plate that two length direction both sides are provided with opening by the crest of its nest shape to crest, and in the spot welding of crest place, and at the both sides of described two plate length directions assembly welding, it is right to form between pipe weld seam and composing plate; Form weld seam between pipe in welding on the width of described two plates, make and form runner between pipe between two right plates of plate, and form runner import and export between pipe at the opening part of described plate length direction; The right adjacent plate group of plate pair and plate to and form weld seam between plate at assembly welding on the length direction of plate, make plate pair and plate between formed runner between plate, the right width of plate is as runner import and export between plate.

The runner import and export is provided with pipeside shell and is being provided with runner import and export between corresponding pipe on the pipeside shell between described heat exchange core body respective tube; The runner import and export is provided with boardside shell and is being provided with runner import and export between corresponding plate on the boardside shell between described heat exchange core body respective panels; Described boardside shell is provided with flange, and by blind plate sealing; Heat exchange core body becomes complete pressure-bearing body by the pressing plate involution.

Nest shape on the described nest shape plate is circle nest and evenly distribution.

Described pipeside shell is a semi circular shells; Described boardside shell is square shell.

The utility model has following advantage compared to existing technology:

1, heat exchange plate of the present utility model be with two nest shape heat exchange plate crests that are provided with opening to crest, it is right to form plates in the spot welding of crest place, four periphery welding, is forming a kind of runner between the little pipe in contact, gap that has between two plates; Runner between the plate in contactless to being combined into by plate again, big gap, and by shell with runner between runner between plate and pipe separately, form two independently flow passage systems, and bear the pressure of system, compact conformation, heat exchange area are big, the heat exchange efficiency height.

2, heat exchange core body of the present utility model adopts welding manner to connect, and does not need the rubber gasket sealing between the runner, thereby applicable to physical characteristics such as higher temperature, pressure.

3, unique plate of the present utility model makes fluid be full of the whole runner that plate forms, and all plate surfaces have nearly all participated in changing exchange, medium can realize not having flowing of " dead band " in runner, so it is smooth and easy that fluid flows, resistance is little, has reduced kinetic energy consumption.

4, after the welding all around of nest shape corrugated cardboard sheet of the present utility model, because the influence of thermal stress causes freely stretching of plate inboard, the plate surface is not easy to form for dirty layer in running; Simultaneously because the unique texture of plate, between pipe in the runner Hydrodynamic turbulence degree big, the dirty thing in plate surface is come off automatically, be difficult for the collection dirt.

5, by opening blind plate, can mechanical easily clean plate between runner.

6, heat exchange plate adopts the segmentation compacting, and length can be chosen arbitrarily as required, and the veneer heat exchange area changes thereupon.
