Description
Technical field
What the present invention relates to is a kind of heat exchanger of enhanced heat exchange technical field.
Background technology
Plate type heat exchanger is widely used in multiple fields such as the energy, power, heat supply, refrigeration owing to the characteristics with heat exchange efficiency height, compact conformation.Maturation along with the plate type heat exchanger technology has replaced traditional shell-and-tube heat exchanger in some fields.But the lower problem of existing rectangular plate type heat exchanger ubiquity bearing capacity.In the higher field of common pressures such as petrochemical industry, the application of plate type heat exchanger has received great restriction.Developing a kind of plate type heat exchanger that can bear high pressure and compact conformation has a wide range of applications in the energy source and power field.Though have some all-welded lamella heat exchangers at present, its operating pressure generally is no more than 4.5MPa, and volume is relatively large, compactness is not high.These all-welded lamella heat exchangers as heat transfer element, and place rectangle or circular housing to promote load performance the plate bundle with rectangular plate.This plate type heat exchanger bearing capacity is limited and volume is bigger.
The channel design of two media is identical in the common plate type heat exchanger, differs some bigger operating modes for both sides heat transferring medium rerum natura, and what can occur designing match, and then causes the waste on volume and the material.For example when utilizing water-cooled but during thick oil; Because oil body is far above the viscosity of water; The flow resistance of lubricating oil can be far above the cooling-water flow resistance under the same traffic; Usually the flow resistance of lubricating oil reaches going up in limited time of designing requirement, and the flow resistance of cooling water side also reaches limit value far away, and this has just caused the waste in the design.
Summary of the invention
The object of the present invention is to provide and be applicable to heat exchange between the variety classes fluid, be particularly suitable for a kind of high voltage bearing circular wave plate lamella heat exchanger that hot rerum natura differs heat exchange between bigger two media.
The objective of the invention is to realize like this:
A kind of high voltage bearing circular wave plate lamella heat exchanger of the present invention; It is characterized in that: comprise housing, cover plate, corrugated plating plate bundle, baffle, gripper shoe, corrugated plating plate bundle comprises corrugated plating, and corrugated plating plate bundle is fixed in the housing through gripper shoe; Cover plate for sealing is passed through at the housing two ends; Shell side outlet, shell side import are set on the housing, the import of plate journey, the outlet of plate journey are set on the cover plate, the annular region of shell and corrugated plating plate interfascicular is separated into shell side inlet plenum and shell side outlet chamber by baffle; The shell side import is communicated with the shell side inlet plenum; The shell side outlet is communicated with shell side outlet chamber, has the hole, angle on the corrugated plating plate bundle, and import of plate journey and the outlet of plate journey are connected through the hole, angle of corrugated plating plate bundle.
The present invention can also comprise:
1, two corrugated platings force together, and to form plate right, and plate forms passage between the plate between shell side outlet, the shell side import to inside, and plate is to being joined together to form corrugated plating plate bundle, plate between form passage between the plate between the import of plate journey, the outlet of plate journey.
2, the import of described plate journey is positioned at the upper end of heat exchanger body, and the outlet of plate journey is positioned at the lower end of heat exchanger body, and the shell side outlet is positioned at shell upper plate journey import one side, and the shell side import is positioned at shell upper plate journey and exports a side.
3, corrugated plating adopts the disk and thin plate of straight ripple or herringbone ripple, and corrugated plating two sides ripple height is different.
Advantage of the present invention is:
1, bearing capacity is strong.Plate adopts all-welded mode to be connected, and without gasket seal, bearing capacity is stronger with the braze welding type plate type heat exchanger than removable.Can occur stress during common rectangular plate pressure-bearing concentrates.Stress distribution is even during the disk and thin plate pressure-bearing that adopts, is difficult for causing damaged the leakage because of stress raisers occurring, and is better than common rectangular plate bearing capacity.In addition, adopt the shell-and-plate design, the plate bundle is enclosed in the housing, further promoted sealing property and bearing capacity.
2, heat exchange efficiency is high.Passage is herringbone or double font wavy channel between the plate in the plate bundle, and the contact point that intersects is many.Fluid between plate in the passage solderless wrapped connection contact become eddy current to flow, flow-disturbing is strong, the effect of augmentation of heat transfer is played in the boundary layer in the time of effectively destroying resisting medium and flow.
3, the heat transfer area in the compact conformation, unit volume is big.Corrugated plating among the present invention is arranged closely, and heat exchanger overall structure compact, and under equal volume, the present invention has bigger heat transfer area than shell-and-tube heat exchanger.Compare with the lamella heat exchanger that adopts rectangular plate, structure is more compact.
4, selection range is wide.Corrugated plating among the present invention can adopt multiple different materials, and the for example stainless steel of various models, copper alloy, titanium alloy etc. are to be applicable to different types of heat transferring medium.
5, applied widely.Circular wave plate both sides ripple height is different, when media of both sides flow, physical parameter differ big, has stronger applicability.And heat exchanger can be designed to multiple path combination with media of both sides according to actual needs.
6, process simply, be easy to install.Asymmetric channel circular wave plate of the present invention is easy to process quick, and with short production cycle, cost is low, is particularly suitable for industrialized mass production.
In sum; The present invention is that a kind of shell-and-tube heat exchanger voltage endurance capability that has both is high and the plate type heat exchanger compactness is strong, the new type of plate shell heat exchanger of the big characteristics of heat transfer coefficient; And have the advantages that the scope of application is wide, reliability is high, be easy to make, have good development and application prospect.
