Abstract
The invention relates to the technical field of fabricating plate type heat transmission elements for heat exchange, in particular to a heat transmission plate for a welding plate type heat exchanger. The heat transmission plate comprises trapezoidal guide areas respectively at the upper and the lower ends of the plate, as well as a rectangular heat transmission area at the middle part, and has the profile of an octagon or an approximate octagon as a whole, wherein access ways for different media are arranged at the two ends of the plate, and the media on two sides run contrarily; and one of the two access ways begins with the outer side top edge of the upper trapezoidal guide area to the arris edges of the two sides of the lower trapezoidal guide area, and the other way begins with the outer side top edge of the lower trapezoidal guide area to the arris edges of the two sides of the upper trapezoidal guide area. The heat transmission plate adopting the structure has the advantages of uniform fluid body distribution, no dead zone as a whole and lesser resisting force at the introduction end.
Description
Technical field
The present invention relates to make heat exchange heat transfer element technical field, relate in particular to a kind of welded plate type heat exchanger heat transferring plate.
Background technology
Heat exchanger is by heat transferring plate cold fluid to be heated to uniform temperature, hot fluid is cooled to uniform temperature, is used for improving heat exchange performance, reduces energy consumption.
Existing welded plate type heat exchanger heat transfer element, mostly be rectangle or square, the liquid form of media of both sides is the cross-current form, for the technique occasion that exists temperature to intersect, single device can't meet the demands, need to adopt many series connection or medium repeatedly to roll over journey in plate and realize, many series connection cause occupation area of equipment to increase, and medium is rolled over the increase of the increasing of Cheng Zaocheng drag losses and contour size of the unit(s) in plate.
The adverse current template that rectangle is also arranged, but a side imports and exports by the termination, and opposite side is imported and exported by the side.Pressure drop is large, and topology layout is limited.
A kind of hexagonal adverse current template is arranged,, skewness large for wider plate pressure drop.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of minimizing to import the end resistance loss, without the welded plate type heat exchanger heat transferring plate of dead band and good evenness.
The present invention is achieved by the following technical programs:
A kind of welded plate type heat exchanger heat transferring plate, comprise guiding region and heat transfer zone, described plate up and down two ends is the trapezoidal shape guiding region, mid portion is rectangular-shaped heat transfer zone, described plate monnolithic case is octagon or approximate octagon, described plate two ends are respectively the access way of different medium, and the media of both sides flow direction is opposite.
In the described plate circulation passage of medium be one by the outside top margin of the upper trapezoid both sides hypotenuse to lower trapezoid, another is by the outside top margin of the lower trapezoid both sides hypotenuse to upper trapezoid.
In the described plate circulation passage of medium be one by the outside top margin of the upper trapezoid outside top margin to lower trapezoid, another is by the both sides hypotenuse of the lower trapezoid both sides hypotenuse to upper trapezoid.
The invention has the beneficial effects as follows:
Be octagon or approximate octagonal welded plate type heat exchanger heat transferring plate owing to be provided with, its plate up and down two ends is the trapezoidal shape guiding region, mid portion is rectangular-shaped heat transfer zone, its two ends are respectively the access way of different medium, the media of both sides flow direction is opposite, this kind mode is so that even fluid distribution is whole less without dead band and importing end resistance.
Description of drawings
Fig. 1 is outline drawing of the present invention.
Fig. 2 is Y-Y type flow pattern schematic diagram of the present invention.
Fig. 3 is the type of falling I-X flow pattern schematic diagram of the present invention.
Among the figure: 1. heat transfer zone, 2. guiding region, A, B are the different medium fluid.
The specific embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, the present invention is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in the figure, the present invention includes guiding region and heat transfer zone, described plate up and down two ends is the trapezoidal shape guiding region, mid portion is rectangular-shaped heat transfer zone, described plate monnolithic case is octagon or approximate octagon, described plate two ends are respectively the access way of different medium, and the media of both sides flow direction is opposite.
In the wherein said plate circulation passage of medium be one by the outside top margin of the upper trapezoid both sides hypotenuse to lower trapezoid, another is by the outside top margin of the lower trapezoid both sides hypotenuse to upper trapezoid.Be the type of falling Y-Y flow pattern.Be that a kind of medium can enter from the outside top margin of upper trapezoid, flow out simultaneously (being inverted Y-shaped flows) from the both sides hypotenuse of lower trapezoid, another kind of medium enters from the limit, outer top side of lower trapezoid, flows out simultaneously (being the Y type flows) from the both sides hypotenuse of upper trapezoid, and both flow directions also can be inverted certainly;
In the another kind of described plate circulation passage of medium be one by the outside top margin of the upper trapezoid outside top margin to lower trapezoid, another is by the both sides hypotenuse of the lower trapezoid both sides hypotenuse to upper trapezoid.Be I-X type flow pattern.Be that a kind of medium can enter from the outside top margin of upper trapezoid, flow out (being the I type flows) from the outside top margin of lower trapezoid, another kind of medium enters simultaneously from the both sides hypotenuse of lower trapezoid, flows out simultaneously (being X-type flows) from the both sides hypotenuse of upper trapezoid, and both flow directions also can be inverted certainly;
The present invention adds man-hour, and plate is different corrugated form through cold moudling, and two ends are the trapezoidal shape guiding region up and down, and the centre is rectangular-shaped heat transfer zone, and plate welds in twos and forms plate pair.Plate groups is to rear, and the plate two ends are respectively the access way of different medium, and the media of both sides flow direction is opposite.Base, outside length, waist height and both sides hypotenuse length and the ratio of plate upper and lower side trapezoidal shape distribution guiding region can be adjusted as required.
The present invention adds man-hour, and plate also can be realized by the mode of weldering muscle, post.
Be octagon or approximate octagonal welded plate type heat exchanger heat transferring plate owing to be provided with, its plate up and down two ends is the trapezoidal shape guiding region, mid portion is rectangular-shaped heat transfer zone, its two ends are respectively the access way of different medium, the media of both sides flow direction is opposite, this kind mode is so that even fluid distribution is whole less without dead band and importing end resistance.
Sheet material can adopt carbon steel, stainless steel, titanium and alloy thereof, nickel and nickel-base alloy thereof or other steel grade or non-ferrous metal.And be applicable to, gas-gas, gas-liquid, the media of both sides such as liquid-liquid are single-phase heat exchange, also are applicable to two-phase-two-phase, the heat exchange of single-phase-two-phase; Its temperature resistant range is at-196-1200 ℃.
