Description
Technical field
The present invention relates to a kind of heat exchanger plate chip technology, especially a kind of novel fishbone adds the plate-type heat-exchange of fusiformis protrusion
Device plate.
Background technology
Plate heat exchanger have compared with shell-and-tube heat exchanger heat transfer coefficient is high, logarithmic mean temperature difference (LMTD) is big, terminal temperature difference is small,
The advantages that floor space is small, light-weight, price is low, easy to make, easy to clean, heat loss is small, less scaling.Plate heat exchanger
Plate is the most important component of plate heat exchanger, and the design of plate directly influences the heat transfer effect of entire plate heat exchanger.
Plate heat exchanger is composed of in a certain order several identical plates, and generally use is as shown in Figure 1
Herringbone plate, the plate include location hole 1, corner apertures 2, guiding region 3, shunting zone 4, heat transfer zone 5, and preceding ripplet 6 is rear small
Ripple 7 and big ripple 8.When fluid flows into plate by corner apertures 2, by guiding region 3 and shunting zone 4, inflow heat transfer zone 5 is being set
It sets on ripply plate and to carry out heat exchange on i.e. heat transfer zone 5.Fluid after heat exchange flows at the corner apertures of the other side, converges
Flow into next group of plate.One other fluid is flowed and is exchanged heat in a reverse direction in the other side of plate simultaneously, by changing
Fluid after heat flows to next group of plate.Plate-type heat exchanger slab is the critical piece for influencing plate heat exchanger performance.Currently, plate
The corrugated shape of the plate of formula heat exchanger is numerous：Herringbone ripple, straight ripple, ladder type is straight ripple, indentation ripple etc..This
A little plate heat transfer zones corrugated shapes are different, but all do not consider how so that even fluid distribution on plate is asked
Topic, this exchange thermal effect have large effect.
Invention content
The purpose of the present invention is to provide the plate-type heat exchanger slab that a kind of novel fishbone adds fusiformis protrusion, fluid distrbutions
More uniformly, heat transfer effect is more preferably.
Realize that the technical solution of the object of the invention is：A kind of novel fishbone adds the plate-type heat exchanger slab of fusiformis protrusion,
Including plate main body, corner apertures, guiding region, shunting zone, heat transfer zone are set in plate main body；Direction is flowed along heat transfer zone heat transferring medium
Axis both sides ripple is set, an angle is set between homonymy ripple and heat transfer zone axis, is arranged between homonymy adjacent corrugations flat
Surface wave paddy, heteropleural ripple are staggered along heat transfer zone axis or so, and the protrusion of several semi-cylindricals is arranged on trough.
Using above-mentioned heat exchanger plate, ripple is equal with the width of trough, and homonymy corrugation end bottom surface both ends and heteropleural
It is overlapped at corresponding trough two edges.
Using above-mentioned heat exchanger plate, waviness width is less than trough width, and homonymy corrugation end bottom surface both ends are positioned at different
Between the corresponding trough two edges in side.
There is enhancing fluid to flow for the novel fishbone plate-type heat exchanger slab structure of the present invention, staggered ripple
Disturbance in road；The fluid staggeredly flowed can reduce heat exchange flow dead zone so that fluid heat transfer zone flow distribution more
Ground is uniform.It is provided with the protrusion of semi-cylindrical at trough, there is disturbance of the enhancing fluid near protrusion, produces secondary strong
Change heat transfer；The protrusion being in tilted layout simultaneously can also play the role of shunting so that distribution of the fluid in heat transfer zone is more uniform.
The presence of protrusion also increases heat exchange area, optimizes the comprehensive performance of plate heat exchanger.
The invention will be further described with reference to the accompanying drawings of the specification.
Description of the drawings
Fig. 1 is the structural schematic diagram of the herringbone plate of existing plate heat exchanger.
Fig. 2 is the novel fishbone plate-type heat exchanger slab structural schematic diagram of the present invention.
Fig. 3 is heat transfer zone structural schematic diagram of the present invention.
Specific implementation mode
In conjunction with Fig. 2, Fig. 3, a kind of novel fishbone adds the plate-type heat exchanger slab of fusiformis protrusion, including plate main body, plate
Location hole 1, corner apertures 2, guiding region 3, shunting zone 4, heat transfer zone 5 are set in piece main body.It rises at the both ends that location hole 1 is located at plate main body
To the effect of positioning.There are four being located on four angles of plate main body, heat transferring medium flows through corner apertures 2 from corner apertures 2.Water conservancy diversion
Area 3 guides heat transferring medium to shunting zone 4.Heat transferring medium is branched to the different region in heat transfer zone 5 by shunting zone 4.On heat transfer zone 5
Setting ripple 11 is flowed to along heat transferring medium.
When heat transferring medium flows into plate by corner apertures 2, by guiding region 3 and shunting zone 4, inflow heat transfer zone 5 is being provided with
It is to carry out heat exchange on heat transfer zone 5 on the plate of ripple.Fluid after heat exchange flows at the corner apertures of the other side, converges inflow
Next group of plate.One other fluid is flowed and is exchanged heat in a reverse direction in the other side of plate simultaneously, after heat exchange
Fluid flow to next group of plate.
The axis both sides that direction is flowed along 5 heat transferring medium of heat transfer zone are arranged ripple 7, homonymy ripple 7 and 5 axis of heat transfer zone it
Between an angle is set, setting plane trough 6 between homonymy adjacent corrugations 7, heteropleural ripple 7 is along 5 axis of heat transfer zone or so staggered row
It arranges, the protrusion 8 of several semi-cylindricals is set on trough 6.
Ripple 7 is equal with the width of trough 6, and at 7 end bottom surface both ends of homonymy ripple, 6 two edges of trough corresponding to heteropleural
It overlaps；Or 7 width of ripple is less than 6 width of trough, and 7 end bottom surface both ends of homonymy ripple are located at corresponding 6 two edges of trough of heteropleural
Between.
Ripple axis and the angle of 5 axis of heat transfer zone are 45 °~60 °.Angle should not be too large or too small, angle it is excessive so that
Most of fluid directly impacts the preceding oblique wave face of ripple, and along the then less of corrugated flowing；Angle is too small, opposite to that, this
Two kinds of situations cannot dispersing fluid well.
The ripple of the fishbone of the present invention is staggered, and has disturbance of the enhancing fluid in runner, in the flowing direction
Secondary Flow is generated, generates secondary whirlpool, the generation of secondary whirlpool enhances heat transfer；The ripple that is staggered allows fluid to interlock
Flowing, while have the function of reduce flow resistance so that fluid heat transfer zone flow distribution more uniformly, optimize
The comprehensive performance of plate heat exchanger.
The major semiaxis of fusiformis protrusion is 4~10mm, and semi-minor axis is 2~5mm, a height of 2~4mm, fusiformis 8 long axis of protrusion and plate
The angle of piece ripple center line is less than the angle of ripple axis and center line, and raised spacing is 3~6mm.Angle should not be too large
Or it is too small, angle is excessive so that most of fluid directly impacts the preceding oblique wave face of ripple, and is flowed along corrugated then less；Folder
Angle is too small, opposite to that.Both of which cannot the fine relationship that must handle flow and resistance, heat transfer effect is slightly more inferior.
Certain spacing is set between each protrusion, and it is discrete.Secondary Flow is generated when fluid flows through protrusion so that flow separation,
Generate local dip, can converge again again in the downstream of flowing, to obtain higher reinforcing effect, thus add again one it is convex
It rises.And continuous protrusion is not only so that disturbance decrease, can also increase resistance.
The shape of the novel plate heat exchanger sheet structure of the heat transfer zone fishbone, ripple is ripple, herringbone anyhow
Ripple, straight ripple, ladder type is straight ripple or the one such shape of indentation ripple.It is identical when heat exchanger assembles
Plate rotates 180 ° of pressings completely.
