Corrugated shape is numerous：Herringbone ripple, straight ripple, ladder type is straight ripple, indentation ripple etc..These plate heat transfer zone ripples
Shape is different, but is all only that exchange thermal region carries out primary reinforcement heat transfer.Therefore present invention research is original
Secondary hardening heat transfer has been carried out on the basis of plate.
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.
Heat transfer zone 5 is also referred to as corrugated regions, and lambdoid ripple is provided in the area.The ripple struction of traditional herringbone's plate is such as
Shown in Fig. 2, the normal section shape of ripple is trapezoidal, and identical period, the crest height of each ripple are used between adjacent corrugations
Unanimously.Although using the plate heat exchanger good effect of heat exchange of herringbone plate, the ripple of traditional herringbone's plate causes relatively
Larger flow resistance so that assignment of traffic is uneven, and affect plate heat exchanger comprehensive performance further increases and apply model
The further expansion enclosed.
Invention content
The purpose of the present invention is to provide a kind of plate heat exchanger herringbone plate, which can reduce in flow process
Resistance, increase heat exchange area, enhanced heat exchange effect makes the comprehensive performance of plate heat exchanger be further enhanced.
Realize that the technical solution of the object of the invention is：A kind of plate heat exchanger herringbone plate, including plate main body, plate
Corner apertures, guiding region, shunting zone, heat transfer zone, heat transfer zone upper edge heat transferring medium flow direction setting herringbone ripple, herringbone are set in main body
Convex is arranged in the preceding ripplet of the one side setting groove-like of shape corrugated surface heat exchanging medium flow direction, herringbone ripple another side
Ripplet afterwards, preceding ripplet are identical with rear ripplet shape.
For the present invention in the wave crest both sides of big ripple setting protrusion and groove, the big ripple side setting towards direction of flow is recessed
Protrusion is arranged backwards to the big ripple side of direction of flow in slot.The design of groove makes fluid increase disturbance, fluid in flow process
Turbulent flow is generated when flowing through groove, or even has a small amount of reflux, so that fluid heat transfer is more thorough.It is this constant in mainstream
In the case of small-scale turbulence strengthen the exchange capability of heat of fluid, the exchange capability of heat of plate entirety obtains secondary reinforcement.Groove
It cannot be overturned with the position of protrusion.If the big ripple side setting protrusion towards direction of flow, centainly streams although can play
Effect, but the increase of resistance is obviously more；Groove is set backwards to the big ripple side of direction of flow, secondary hardening effect can weaken
Very much.The setting of groove and protrusion enhances heat-transfer effect, and the comprehensive performance of plate heat exchanger is made to be further enhanced.
The invention will be further described with reference to the accompanying drawings of the specification.
