Description

A kind of New Evaporator plate

Technical field

The utility model 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 utility model provides a kind of New Evaporator plate, the New Evaporator plate Runner inner fluid speed can be improved, boundary layer is thinned, increase temperature gradient, when fluid flows through or entersθAngle is double to open triangle squama When piece, strong perturbation action is generated, to greatly improve its comprehensive performance.

Technical solution used by the utility model is：New Evaporator plate by tabula rasa andθAngle is double to open triangle scale Composition, it is characterised in that：The plate, cracks on tabula rasa first, then stamps out the square row of sequence protrusion recess ClothθAngle is double to open triangle scale.

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.

It is describedθAngle is double to open triangle scale sequence protrusion recess on plate, square arrangement, when fluid flow through or into EnterθWhen triangle scale is opened at angle pair, fluid boundary layer is thinned, to make newly in the strong disturbance effect of generation constantly impact scale The comprehensive performance of type evaporator plate is largely better than common plate.

The main structure parameters of the New Evaporator plate have：Tabula rasa thicknessδ _f , adjacent scale spacing c _f , scale to plate Piece back gaugeb _f , triangle scale opening angleθ, 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 scale opening direction.

Compared with the common plate of existing evaporator, the utility model has the beneficial effects that：1, the runner that novel sheet bar is formed, Fluid is flowing through or into runnerθWhen triangle scale is opened at angle pair, fluid existsθAngle is double to open triangle scale protrusion and recess Opening vertically flows into, and at scale, fluid mutually impacts plate face up and down, local differential pressure action is formed, to generate longitudinal direction Whirlpool and perturbation action, guidance mainstream impact scale, improve the velocity gradient at scale；2, the New Evaporator plate Piece, the flow velocity of the uneven formation regional area of speed and the pressure distribution of fluid is accelerated in runner, so that boundary layer be thinned；3, Versatility is preferable, while perfection replaces original plate, can also be independent or be used in mixed way with common plate.4, various criterion Plate correspond to corresponding structural parameters, 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 utility model 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, wherein：Plate width isW, plate length isL, sheetδ _f =2mm, adjacent scale spacing c _f =30mm, Scale is to plate back gaugeb _f =20mm, triangle scale opening angleθ=30 °, Fig. 4 is New Evaporator plate adjacent channels point Butut, flow channel entry point along perpendicular toθAngle is double to open triangle scale opening direction.

The runner that the utility model evaporator plate is formed, fluid open triangle at the angle θ flowed through or into runner pair When scale, fluid is opened triangle scale opening at the angle θ pair and is vertically flowed into, at scale, the mutual impact of fluid above and below plate face, The differential pressure action of part is formed, to generate longitudinal whirlpool and perturbation action, guidance mainstream impacts scale, makes the speed at scale Gradient is improved；Since the flow velocity of the uneven formation High Velocity Area of speed and the pressure distribution of fluid in runner is accelerated, from And boundary layer is thinned；In conclusion the special construction accelerate runner in local velocity, be thinned boundary layer, increase temperature gradient with And generate strong perturbation action and move, 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：Plate after opening is put into mold, and the square arrangement of sequence protrusion recess is stamped out on mold The angle θ double open triangle scale.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
