The use of being detained the piece slot has improved the clearance ability of the interior dirt of plate heat exchanger, has improved the fluidic velocity of flow. Improve the flow guiding areas structure simultaneously, improved local reynolds number, reduced the flow resistance of medium, improved heat exchange efficiency.
Description
Technical field
This utility model relates to stagnant area disturbance plate, and it belongs to the technical field of heat exchanger processing and manufacturing.
Background technology
Current heat-exchangers of the plate type is requisite equipment in industry diabatic process, it is widely used in the industrial circles such as chemical industry, oil, iron and steel, automobile, food, light industry, simultaneously it be also air-conditioning, the important component part Gong hankering, it is the key equipment in UTILIZATION OF VESIDUAL HEAT IN, Solar use, sewage intercepting well, seawater utilization, geothermal utilization.
Owing to current most heat-exchangers of the plate type all adopts dismountable plate type heat exchanger, the plate heat exchanger plate material of present most enterprise mainly adopts 304,316 or 316L etc., plate type heat exchanger is conducted heat by many corrugated plates, the dismountable heat transmission equipment formed in certain intervals.Plate assemble time two groups alternately arranged, heat exchange plate is pressed into various corrugated, to increase area and the rigidity of heat exchange plate, and fluid can be made to form turbulent flow at low flow rates, to reach the effect of augmentation of heat transfer.Four corner apertures of plate, define the distribution pipe of fluid and let out collector, and two kinds of heat transferring mediums separately flow into respective runner, form adverse current and flow the exchange being carried out heat by each plate.
Heat transferring plate is the core parts of plate type heat exchanger, and whether the structure of guiding region is reasonable, the performance of the heat exchanger having a strong impact on.Rational guiding region structure, it is possible to be that fluid changes region at plate and is uniformly distributed by design idea, declining thus avoiding the heat exchange efficiency that assignment of traffic is uneven and flow blind angle brings, it also avoid the drawback of fouling etc..
The design of plate guiding region in current domestic plate type heat exchanger, dead angle fouling for the stream process of fluid seems can not well control and clear up, likely increase the resistance within heat exchanger and pressure in this case, such cost will improve a lot, and difficulty of processing increases, processing cost is all by increase at double simultaneously.User also to undertake the efficiency of very big cost, the utilization being unfavorable for heat-exchangers of the plate type and the heat exchange reducing plate type heat exchanger.For the problem existing for above-mentioned prior art, research design stagnant area disturbance plate, thus overcome prior art there is a problem that very necessary.
Summary of the invention
For solving problems of the prior art, this utility model provides stagnant area disturbance plate, to reach applying working condition requirement, and reduces the manufacturing cost of heat-exchangers of the plate type, to solve in plate type heat exchanger the problem that plate heat transfer effect is unbalanced, heat exchange efficiency is low.
The technical solution adopted in the utility model is: stagnant area disturbance plate, seal groove including plate frame and plate periphery, described plate also includes hole, location, corner apertures, flow deflector and corrugated plate, the region that flow deflector is formed is guiding region, the region that corrugated plate is formed is corrugated regions, communicates between guiding region with corrugated regions；Be provided with in the middle of described corrugated regions and redistribute passage, described in redistribute the width of passage be 8mm, the degree of depth redistributing passage is 5mm；Described guiding region adjacent is provided with by being detained the stagnant area that sheet is constituted, and described delay sheet is provided with the delay sheet groove being perpendicular to water (flow) direction, and the width being detained sheet groove is 3mm, and the degree of depth being detained sheet groove is 2mm, and the length being detained sheet groove is 5mm.
The beneficial effects of the utility model are: this plate includes plate frame, seal groove, hole, location, corner apertures, flow deflector and corrugated plate, it is divided into guiding region, corrugated regions and stagnant area, it is provided with in the middle of guiding region and redistributes passage, stagnant area is provided with on Transverse to the flow direction delay sheet groove.The use being detained sheet groove improves the cleaning ability of dirt in plate type heat exchanger, improves the flow velocity of fluid.Improve guiding region structure simultaneously, improve local Reynolds number, reduce the flow resistance of medium, improve heat exchange efficiency.

Detailed description of the invention
Fig. 1, Fig. 2 and Fig. 3 illustrate stagnant area disturbance plate, and it includes plate frame 6, the seal groove 5 of plate periphery, hole 1, location, corner apertures 2, flow deflector 3 and corrugated plate 4.The region that flow deflector 3 is formed is guiding region, and the region that corrugated plate 4 is formed is corrugated regions, communicates between guiding region with corrugated regions；Being provided with in the middle of corrugated regions and redistribute passage 8, the width redistributing passage 8 is 8mm, and the degree of depth redistributing passage 8 is 5mm；Guiding region adjacent is provided with by being detained the stagnant area that sheet 7 is constituted, and is detained sheet 7 and is provided with the delay sheet groove 7a being perpendicular to water (flow) direction, and the width being detained sheet groove 7a is 3mm, and the degree of depth being detained sheet groove 7a is 2mm, and the length being detained sheet groove is 5mm.
When adopting technique scheme work, current are entered guiding region by the corner apertures 2 of top, the top of corrugated regions is entered by the guiding region water conservancy diversion of top, have again redistribute passage 8 current are redistributed enter corrugated regions bottom, it is pooled to the guiding region of lower section again, enters back in the corner apertures 2 of lower section and circulate.Water in the corner apertures 2 of top also can flow into the stagnant area of plate, and current can be produced perturbation action by the delay sheet groove 7a set up in the side vertical with current, improves the dirt cleaning ability of plate.
