Specific embodiment
Referring to Fig. 1 to Fig. 4, the utility model relates to a kind of plate of high pressure resistant efficient brazing plate type heat exchanger, the plates
Piece 1 is made of stainless steel material, ensure that manufactured heat exchanger can be permanent durable, the plate opens up on 1 positive four angle
There is through-hole, wherein the through-hole Yu thermal medium in the upper left corner flow into through-hole 2, and the through-hole in the lower left corner is that thermal medium flows out through-hole 3, the lower right corner
Through-hole be that cold medium flows into through-hole 4, the through-hole in the upper right corner is that cold medium flows out through-hole 5, and cold medium flows into through-hole 4 and cold medium
The aperture for flowing out through-hole 5 is greater than the aperture that thermal medium flows into through-hole 2 and thermal medium outflow through-hole 3, so that after soldering plate combination
Cold medium delivery rate be greater than thermal medium delivery rate, can be effectively reduced the temperature of thermal medium, improve heat transfer effect.
Such as Fig. 4, these through-holes are connected with medium pipeline is respectively formed the runner of hot and cold medium, and wherein thermal medium is before most
The thermal medium of one piece of face plate 1 flows into through-hole 2 and enters, after flowing through in the runner between each adjacent plate 1, from foremost
The thermal medium outflow through-hole 3 of one piece of plate 1 flows out, and cold medium flows into through-hole 4 from the cold medium of end plate and enters, each adjacent
Plate 1 between runner in flow through after, from the cold medium of end plate outflow through-hole 5 flow out.
The front of the plate 1 is intermediate to offer a plurality of ripple 6 from top to bottom, and the ripple 6 is in herringbone, lambdoid
It is arranged and increases the contact area of cold and hot medium, so that cold and hot medium has bigger heat exchanger time on plate 1, further mentions
High exchange rate, every lambdoid ripple 6 is made of symmetrical left side raised line 7 and right side raised line 8, and plate 1 four
A circle convex block 9 is provided on the outside of through-hole on a angle, plate 1 is the convex of plate 1 at left side raised line 7, right side raised line 8, convex block 9
Top 10, remaining position are the concave bottom 11 of plate 1.
In all ripples 6 of the plate 1, as soon as at interval of ripple 6, the surface of ripple 6 is provided with boss 12, described convex
Platform 12 is evenly arranged in the left side raised line 10 of the left and right sides, on right side raised line 11, these dotted small boss 12 are arranged in dotted
In the heat exchange zone of adjacent two boards piece 1, when gap of the fluid between two boards piece 1 passes through, these ripples 6 and boss 12
So that fluid is constantly changed flow direction, generate the movement such as rotation and torsion, form many fine vortex, to make each in fluid
Partial particle constantly shifts rapidly, carries out heat exchange rapidly, and the great turbulence level of fluid also reduces suspended particulates and exchanging heat
Deposition and fouling on face, external waviness also make practical heat exchange area increase tens percent, and all of these factors taken together all significantly adds
Strong diabatic process, makes its general shell-and-tube exchanger of ratio of heat transfer coefficient improve several times, while just setting every a ripple 6
There is boss 12, heat transfer space can be affected too much to avoid boss 12 in this way.After the combination of plate 1 compresses, adjacent two pieces
The boss 12 on herringbone ripple 6 between plate 1 contacts with each other, and forms the crowd that many supporting points, especially exchange area are formed
More solder joints greatly strengthen the rigidity of plate 1, therefore, although the very thin thickness of each plate 1, can also bear quite high
Pressure.
