Description
Technical field
The utility model is related to heat exchanger fields, particularly a kind of plate type heat exchanger.
Background technology
Heat-exchange device is the device that a kind of heat of fluid is transmitted to one other fluid.All heating equipments can full factory
It is public, it can also be with the mating setting of steam turbine.At present, geothermal energy field is mostly using plate heat exchanger, due to underground heat aqueous corrosion
Influence, the service life that the stainless steel material used uses is also only there are three moon or so, and general shell-and-tube heat exchanger plate exists
The problems such as media flow resistance is big, energy consumption is big, heat transfer efficiency is low.
Utility model content
The utility model aim is to provide a kind of plate type heat exchanger, and to solve existing heat exchanger, there is media flows
The technical problems such as resistance is big, energy consumption is big, heat transfer efficiency is low.
To solve the technical issues of above-mentioned, the utility model provides a kind of plate type heat exchanger, including heat-exchanger rig, institute
Stating heat-exchanger rig includes fixed pressure plate, plate, gasket, intermediate bulkhead, movable pressure plate, and the top of the fixed pressure plate is set
There are interface and flange, intermediate bulkhead, the fixed pressure plate and centre are equipped between the fixed pressure plate and movable pressure plate
Multiple plates are equipped between partition plate, multiple plates are equipped between the intermediate bulkhead and movable pressure plate, the plate is equipped with
Gasket, the bottom of the movable pressure plate are equipped with interface and flange；The fixed pressure plate bottom is additionally provided with screw hole.
Preferably, the center section of the top and bottom of the intermediate bulkhead, plate, movable pressure plate is equipped with rectangle
Groove.
Preferably, being set on the plate, there are four corner apertures, the top joints and activity of the corner apertures and fixed pressure plate
The interface of pressure strip bottom is adapted.
Preferably, the through hole being adapted with corner apertures also is provided on the top and bottom of the intermediate bulkhead.
Preferably, the fixed pressure plate bottom is additionally provided with observation window.
The utility model proposes a kind of plate type heat exchanger heat can be spread out of, wherein plate valve passage is a kind of changeable
Tortuous passageway, fluid therebetween by be it is continuous change flow direction, flow velocity, generate strong turbulent flow, then liquid film thermal resistance very little,
So as to obtain very high heat transfer coefficient, 3-5 times of shell-and-tube heat exchanger may generally be.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The specific embodiment of the present invention is further described with reference to embodiment, is not therefore limited the present invention
System is among the embodiment described scope.
As shown in Figure 1, a kind of plate type heat exchanger, including heat-exchanger rig, heat-exchanger rig includes movable pressure plate 8, plate
6th, gasket 62, intermediate bulkhead 7, fixed pressure plate 5.The top of fixed pressure plate 5 is equipped with interface 53 and flange 52, fixed pressure plate
Intermediate bulkhead 7, movable pressure plate 8 are equipped between 5 and pillar 1, multiple plates are equipped between fixed pressure plate 5 and intermediate bulkhead 7
6, multiple plates are equipped between intermediate bulkhead 7 and movable pressure plate 8, plate 6 is circumferentially with gasket 62, and four are sealed by gasket 62
Week.It is set on plate there are four corner apertures, corner apertures is adapted with the top joint of fixed pressure plate and the interface of movable pressure plate bottom；
The through hole being adapted with corner apertures also is provided on the top and bottom of intermediate bulkhead, intermediate bulkhead is suitable for a variety of media for heat exchange.Four
A corner apertures forms the distribution pipe and manifold trunk of fluid, while again reasonably separates cold fluid and hot fluid, makes it respectively in every block of plate
It is flowed in two side runners of piece, heat exchange is carried out by plate.
5 bottom of fixed pressure plate is equipped with screw hole, and the side of fixed pressure plate 5 and movable pressure plate 8 is equipped with corresponding more
A screw hole is installed with fastening screw in the screw hole, and fastening screw rear and front end is fixed by nut.Facilitating entirely to fill
Put fit sealing, prevent leakage.
5 bottom of fixed pressure plate is additionally provided with observation window 54, for observing the state of media for heat exchange.
Finally it is pointed out that Yi Shang specific embodiment is only the more representational example of the utility model.Obviously, originally
Utility model is not limited to above-mentioned specific embodiment, and acceptable there are many deformations.Every foundation the technical essence of the utility model
To any simple modification, equivalent change and modification that more than specific embodiment is made, it is considered as belonging to the utility model
Protection domain.
