Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
It is an object of the invention to provide a kind of plate for plate type heat exchanger and the plate type heat exchanger with the plate, with
The problem of prior art is present is solved, plate type heat exchanger is not easily blocked on the premise of possessing high heat exchange efficiency.
The present invention provides a kind of plate for plate type heat exchanger, and plate surrounding is provided with the middle part of four corner apertures, plate and set
It is equipped with several pits and several is raised, the pit is interspersed with the projection, and the pit is in the projection
Star.
The pit and bulge-structure that the present invention is set thereon for the plate of plate type heat exchanger can form cold and hot medium
Flow channel, on the one hand, the cross-sectional area by pit and the flow channel of the raised cold and hot medium separately constituted is big, carries significantly
The high anti-blockage capability of plate type heat exchanger；On the other hand, star pit and raised presence are to increase plate both sides cold and hot
The effect of inducing fluid turbulent flow is served while the contact area of medium, so as to ensure that the high heat exchange effect of plate type heat exchanger
Rate, pit and projection can be arranged as required into not equal altitude, therefore be also highly suitable for use in cold and hot rate-of flow than big spy
Different occasion.
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
The present invention provides a kind of plate for plate type heat exchanger, as shown in figure 1, the corner of plate 1 is provided with four angles
Hole 101, several pits 103 and several projections 102 are provided with the middle part of plate 1, and pit 103 staggeredly divides with projection 102
Cloth, the size all same of whole pit 103, the size all same of whole projection 102；The size of pit 103 and projection 102
And particular number according to the size of plate 1 can make reasonable design by those skilled in the art, in the present invention not to pit 103
And the quantity of projection 102 makes limitation；Pit 103 is raised in starriness with projection 102, and bottom, the projection of pit 103
102 top is plane, and the bottom surface of pit 103, the top surface of projection 102 are rounded.The depth of pit 103 and projection 102
Height it is different.
The present invention also provides a kind of plate type heat exchanger, including several above-mentioned plates 1 for plate type heat exchanger, adjacent
Two plates 1 are oppositely arranged, and the corner apertures 101 opened up on two adjacent plates 1 is corresponding, the pit of adjacent two plates 1
103 bottom surface or the top surface of projection 102 are in contact, and the flowing that the pit 103 or projection 102 being oppositely arranged constitute cold and hot medium is led to
A gasket seal 2 for being used to form two media passage is provided between road, and two neighboring plate 1.
As shown in figure 3, pad 2 includes two plate corner apertures sealing rings 201 and a plate peripheral sealing circle 202, it is adjacent
Corner apertures 101 corresponding to two corner apertures sealing rings 201 of two pads 2 is different, and the side of same plate 1 can be made by being arranged such
Only flow a kind of medium, and ensure that the both sides flowing of same plate 1 is different two medias.Pit in the present embodiment
The height of 103 depth and projection 102 is set to difference, and being arranged such can make the width of two kinds of flow channels different, specifically
Ground can make the medium of wider flow channel flowing big flow, and narrower flow channel flows the medium of low discharge.
Pad 2 is designed using integrated formed structure, to ensure the overall sealing property of pad 2 and its making, in this implementation
Two corner apertures sealing rings 201 are located at the same side of pad 2 in example, naturally it is also possible to make two angle sealing rings in pad 2 in pair
Angle is set.
The correspondence pad 2 of plate 1 sets fluted 104, and groove 104 is used to install pad when constituting heat exchanger, it is ensured that heat exchange
Device good seal.
All plates 1 and pad 2 in plate type heat exchanger are linked together by clamping plate, lower and upper cross-member, bolt etc.,
In the presence of the clamping force of bolt, together with adjacent plate 1 is brought into close contact with pad 2.
It should be noted that the pit set in the present invention on plate is not limited with raised shape with the present embodiment,
On the basis of realizing that the present invention sets the different bulge-structure in two kinds of directions on plate, pit is set with raised shape
For other shapes also can, such as taper, cylinder；Equally, the concrete structure design of pad is not limited with the present embodiment, as long as
Can realize makes the both sides of same plate flow two kinds of different media and ensure the sealing between adjacent plate；Four angles
The specific set location in hole is not also limited with the present embodiment, and four corner apertures guarantees are arranged on the inner side of four sides of plate also
Can；In addition, the bottom surface of the pit of plate adjacent in the present invention or the bottom of projection need not also be contacted, although be so oppositely arranged
Pit or projection can not constitute the flow channel of relative closure, but have no effect on and constitute one between two plates being oppositely arranged
Individual overall flow channel, therefore limitation should not be designed specifically to the present embodiment.
Specific case is applied in the present invention to be set forth the principle and embodiment of the present invention, above example
Illustrate the method and its core concept for being only intended to help to understand the present invention；Simultaneously for those of ordinary skill in the art, according to
According to the thought of the present invention, it will change in specific embodiments and applications.In summary, this specification content
It should not be construed as limiting the invention.
