Description
Technical field
The present invention relates to a kind of heat exchanger plate chip technology, especially a kind of plus shuttle shape protrusion plate-type heat exchanger slab
Background technique
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 occupied area is small, light-weight, price is low, easy to make, easy to clean, heat loss is small, less scaling, is frequently used in city
City's heating and refrigeration, petrochemical industry, waste heat recycling, the fields such as food processing.Plate-type heat exchanger slab is that plate heat exchanger is most heavy
The component wanted, the design of plate directly influence the heat transfer effect of entire plate heat exchanger.
Plate heat exchanger is composed of in a certain order several identical plates, is generallyd use as shown in Figure 1
Herringbone plate, the plate include including 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 main component 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.
Summary of the invention
The purpose of the present invention is to provide a kind of plus semicolumn protrusion plate-type heat exchanger slab, which can carry out two
Secondary augmentation of heat transfer.
Realize the object of the invention technical solution be：A kind of plus shuttle shape protrusion plate-type heat exchanger slab, including plate master
Body, is arranged corner apertures, guiding region, shunting zone, heat transfer zone in plate main body, flows to setting ripple, wave along heat transferring medium on heat transfer zone
The protrusion of shuttle shape is provided at the trough of line.
Using above-mentioned heat exchanger plate, the major semiaxis of shuttle shape protrusion is 4-10mm, and semi-minor axis is 2~5mm, a height of 2~
4mm。
Using above-mentioned heat exchanger plate, the angle of long axis and plate ripple center line is 45 °~60 °, raised spacing is 3~
6mm。
The plate-type heat exchanger slab of protrusion of the invention plus shuttle shape, passes through the edge on the mainstream heat transfer zone of plate heat exchanger
The convex block that shuttle shape is had additional at the trough of ripple flow direction has disturbance of the enhancing fluid in runner, generates in the flowing direction
Secondary Flow, generates secondary whirlpool, and the generation of secondary whirlpool enhances heat transfer；The protrusion being in tilted layout simultaneously can also play shunting
Effect so that distribution of the fluid in heat transfer zone is more uniform, and is reduced the pressure loss of the fluid in runner；
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.
Detailed description of the invention
Fig. 1 is the cross section of fluid channel schematic diagram that conventional corrugation plate piece is constituted.
Fig. 2 is the cross section of fluid channel schematic diagram that conventional corrugation plate piece is constituted.
Fig. 3 is the heat transfer zone structural model figure of the plate-type heat exchanger slab of the protrusion of the present invention plus shuttle shape.
Fig. 4 is the partial enlargement three-dimensional model diagram of the structure of the plate-type heat exchanger slab of the protrusion of the present invention plus shuttle shape.
Specific embodiment
In conjunction with Fig. 3, Fig. 4, the plate-type heat exchanger slab of a kind of plus semicolumn protrusion, including plate main body, in plate main body
Location hole 1, corner apertures 2, guiding region 3, shunting zone 4, heat transfer zone 5 are set.Play positioning in the both ends that location hole 1 is located at plate main body
Effect.There are four being located on four angles of plate main body, heat transferring medium flows through corner apertures 2 from corner apertures 2.Guiding region 3 will be changed
Thermal medium is guided to shunting zone 4.Heat transferring medium is branched to the different region in heat transfer zone 5 by shunting zone 4.Along heat exchange on heat transfer zone 5
Medium flow direction setting ripple 11, ripple are symmetrical arranged, i.e., identical plate rotates 180 ° of pressings completely.11 shape of ripple is
Anyhow ripple, herringbone ripple, straight ripple, ladder type is straight ripple or the one such shape of indentation ripple.Adjacent corrugations
Between be in plane trough.Ripple not only can augmentation of heat transfer, but also can increase thin plate and rigidity, to improve plate-type heat-exchange
The bearing capacity of device, and due to promoting liquid in turbulence state, therefore can reduce the formation of sediment or dirt, it plays certain
" self-cleaning " effect.
The protrusion 12 of several shuttle shapes is arranged in the present invention at each trough 13, when the fluid of flowing flows through protrusion 12, meeting
Vortex is generated, secondary flow can not only play the role of shunting, so that distribution of the fluid in heat transfer zone is more uniform, and
Fluid flowing can be reduced to the strong souring of plate；The presence of protrusion also increases heat exchange area, optimizes board-like change
The comprehensive performance of hot device.
The major semiaxis of shuttle shape protrusion 12 is 4-10mm, and semi-minor axis is 2~5mm, a height of 2~4mm.In long axis and plate ripple
The angle of heart line is 45 °~60 °, and raised spacing is 3~6mm.
The protrusion of inclination arrangement can not only play the role of shunting, so that distribution of the fluid in heat transfer zone is more uniform,
And fluid flowing can be reduced to the strong souring of plate；The presence of protrusion also increases heat exchange area, optimizes plate
The comprehensive performance of formula heat exchanger.
Angle should not be too large or too small, the excessive preceding oblique wave face for making most of fluid directly impact ripple of angle, and edge
Corrugated flowing it is then less；Angle is too small, opposite to that.Both of which cannot the fine pass that must handle flow and resistance
System, heat transfer effect are slightly more inferior.
Certain spacing is set between each raised 12, and it is discrete.Secondary Flow is generated when fluid flows through protrusion, so that
Flow separation generates local dip, can converge again again in the downstream of flowing, to obtain higher strengthening effect, thus add again
Add a protrusion.And continuous protrusion weakens disturbance, also will increase resistance.
