Description
Technical field
The present invention relates to a kind of New Evaporator plates, belong to enhanced heat exchange and industrial energy saving technical field.
Background technique
Evaporator is a kind of general thermal power mechanical equipment, is to freeze in four big parts critically important one, because it is being made
Not replaceable effect, is rapidly developed in every field in cold industry.It has been widely used in chemical industry, food work
The fields such as industry, pharmacy, aviation, space division, petrochemical industry, refrigeration, air-conditioning, profound hypothermia.
Evaporator plate sheet type plays decisive role to the efficiency of evaporator, therefore, reinforces the theory of evaporator plate
Research and research and development of products, it is essential for so that it is played a role in wider field.But nowadays China, evaporator plate
R & D Level is lower, and autonomous property right limited, the plate being able to produce is very single, and plate is the core component of evaporator,
The design of plate will directly influence the heat transfer effect of entire evaporator.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of New Evaporator plate, which can be mentioned
Boundary layer is thinned in high runner inner fluid speed, increases temperature gradient, when fluid flows through or enters 1/4 spherical backpack body, generates strong
Strong Secondary Flow, to greatly improve its comprehensive performance.
The technical scheme adopted by the invention is that: New Evaporator plate is made of tabula rasa and 1/4 spherical backpack body, feature
Be: the plate cracks on tabula rasa first, then stamps out intersection protrusion recess, the spherical packet in the 1/4 of square arrangement
Body.
The New Evaporator plate overall dimension is identical as common plate, has good versatility, not only may be used
Replace original plate with perfection, and can be used in mixed way individually or with common plate.
Described 1/4 spherical backpack body intersects protrusion recess, square arrangement, when fluid flows through or enter 1/4 on plate
When spherical backpack body, the strong Secondary Flow of generation constantly impacts backpack body, fluid boundary layer is thinned, to make New Evaporator plate
Comprehensive performance is largely better than common plate.
The main structure parameters of the New Evaporator plate have: tabula rasa thicknessδ f , adjacent backpack body spacing c f , backpack body radiusR, backpack body to plate back gaugeb f , the plate of various criterion corresponds to corresponding structural parameters, makes best performance.
The New Evaporator plate, runner forms media flow heat exchange area between New Evaporator plate, adjacent novel
By supporting with tube wall and welding box body between evaporator plate, fluid is flowed into along vertical backpack body opening direction.
Compared with the common plate of existing evaporator, the beneficial effects of the present invention are: the runner that 1, novel sheet bar is formed, fluid
In the 1/4 spherical backpack body flowed through or into runner, fluid is vertically flowed into 1/4 spherical backpack body high spot, at backpack body, plate
The mutual impact of fluid, forms local differential pressure action above and below face, so that longitudinal whirlpool and Secondary Flow are generated, guidance mainstream impact
Backpack body inner surface improves the velocity gradient at backpack body；2, the New Evaporator plate, the speed and pressure of fluid in runner
The flow velocity of the uneven formation regional area of power distribution is accelerated, so that boundary layer be thinned；3, versatility is preferable, replaces in perfection former
While having plate, can also individually or be used in mixed way with common plate.4, the plate of various criterion corresponds to corresponding structure ginseng
Number, to optimize performance to greatest extent.

Specific embodiment
By taking tabula rasa is with a thickness of the plate of 2mm as an example, further explanation is made to the present invention in conjunction with attached drawing.
Fig. 1 is New Evaporator plate overall schematic, and Fig. 2 is New Evaporator plate top view, and Fig. 3 is novel evaporation
Device plate left view, in which: plate width isW, plate length isL, sheetδ f =2mm, backpack body radiusR=10mm is adjacent
Backpack body spacing c f =30mm, backpack body to plate back gaugeb f =20mm, Fig. 4 are New Evaporator plate adjacent channels distribution map, stream
Road enters opening's edge perpendicular to 1/4 spherical backpack body opening direction.
The runner that evaporator plate of the present invention is formed, fluid is in the 1/4 spherical backpack body flowed through or into runner, fluid
It is vertically flowed into 1/4 spherical backpack body high spot, at backpack body, the mutual impact of fluid above and below plate face forms local pressure difference and makees
With to generate longitudinal whirlpool and Secondary Flow, guidance mainstream impacts backpack body inner surface, changes the velocity gradient at backpack body
It is kind；Since the flow velocity of the uneven formation High Velocity Area of speed and the pressure distribution of fluid in runner is accelerated, so that boundary be thinned
Layer；In conclusion the special construction accelerates local velocity in runner, boundary layer is thinned, increase temperature gradient and generates strong
Secondary flow, integration capability is remarkably reinforced.
The processing method of the utility model evaporator plate is further illustrated with reference to the accompanying drawing.
Preparation stage: according to the plate of measure corresponding size.
Opening stage: according to corresponding size in tabula rasa upper opening.
The punching press stage: the plate after opening is put into mold, and the square arrangement of alternately protrusion recess is stamped out on mold
1/4 spherical backpack body.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
