Specific embodiment
Referring to Fig. 1 to Fig. 3, the utility model relates to a kind of high pressure resistant efficient brazing plate type heat exchanger, in the heat exchanger
Between by being brazed after 1 laid out in parallel of muti-piece metal sheet, plate 1 is made of stainless steel material, ensure that device can be permanent resistance to
With the front end of plate 1 is fixed by front end-plate 2, and the rear end of plate 1 is fixed by end plate 3, the front end-plate 2 and end plate 3
Surface opened up respectively there are two pipe interface 4, wherein inferior horn offers 5 He of thermal medium inlet on the positive left side of front end-plate 2
Thermal medium outlet 6, inferior horn offers cold medium import 7 and cold medium outlet 8 on the positive left side of end plate 3, and plate 1 is arranged side by side
After cloth, through-hole is offered on four angles of every piece of plate 1, through-hole is connected with pipe interface 4, is respectively formed the stream of hot and cold medium
Road.Wherein thermal medium enters from the upper left corner thermal medium inlet 5 of front end-plate 2, flows in the runner between each adjacent plate 1
Later, it being flowed out from the lower left corner thermal medium outlet 6 of front end-plate 2, cold medium enters from the lower left corner cold medium import 7 of end plate 2,
After being flowed through in runner between each adjacent plate 1, from 8 outflow of the upper left corner cold medium of end plate 2 outlet.
The front of the plate 1 is intermediate to offer a plurality of ripple 9 from top to bottom, and the ripple 9 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 9 is made of symmetrical left side raised line 10 and right side raised line 11, and plate 1
A circle convex block 12 is provided on the outside of through-hole on four angles, plate 1 is plate at left side raised line 10, right side raised line 11, convex block 12
The convex top 13 of piece 1, remaining position are the concave bottom 14 of plate 1, and the aperture that cold medium import 7 and cold medium export 8 is greater than thermal medium
The aperture of import 5 and thermal medium outlet 6, so that the cold medium delivery rate after soldering plate combination is greater than thermal medium conveying speed
The temperature of thermal medium can be effectively reduced in rate, improves heat transfer effect.
In all ripples 9 of the plate 1, as soon as at interval of ripple 9, the surface of ripple 9 is provided with boss 15, described convex
Platform 15 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 15 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 9 and boss 15
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 9
There is boss 15, heat transfer space can be affected too much to avoid boss 15 in this way.After the combination of plate 1 compresses, adjacent two pieces
The boss 15 on herringbone ripple 9 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.
Furthermore stiffening plate is increased at the runner interface position of plate 1, the stress levels of heat exchanger can be improved, keep it suitable
For the biggish applying working condition of operating pressure.
