Abstract
The utility model discloses an asymmetric plate-type heat exchanger, belonging to a heat exchange apparatus, and is formed by the overlapping of special plate sheets with sine corrugations on the surfaces, and two adjacent channels are the asymmetric channels whose sectional areas of cold and heat side channels are unequal, and the asymmetric channels are formed by the overlapping of the corrugations of the plate sheets in a reverse direction or a consequent direction. The asymmetric plate-type heat exchanger has the advantages of good heat exchange performance and small resistance, and is used for the heat exchange of fluid with the performance of scale formation, or silt particulate matter, and flow can be unobstructed, and the scale formation and corrosion can be delayed, and the utility model can be widely used in the occasions of the liquid-liquid heat exchange of geothermal water and chemical fluid.
Description
The utility model belongs to heat-exchange apparatus.
Plate type heat exchanger at present commonly used (being called for short P.H.E) is all the symmetric form passage, promptly forms periphery and seals by elastomeric material with the hole, angle by the identical corrugated cardboard sheet of shape is folded mutually, and alternate these passages that flow through of cold and hot fluid carry out heat exchange.So-called " symmetry " is meant that the channel cross-sectional area that cold and hot fluid passes through is identical, and the heat exchanger of this pattern is applicable to that the field boundary of hot and cold flow equity closes.For example, the BJ-02 sawtooth pattern plate type heat exchanger that BR-02A is chevron shaped and cooler factory in Yingkou produces of Tianjin plate type heat exchanger factory production is the plate type heat exchanger of symmetric form passage all just.But, if hot and cold both sides flow differs greatly, just will make a side be forced to be arranged to multipaths, opposite side is few flow process or single process, so not only the both sides pressure drop is differed greatly, and effective heat transfer temperature difference is reduced, and has weakened heat-transfer effect.
The purpose of this utility model provides a kind of asymmetric plate type heat exchanger that is used for liquid-liquid heat exchange and new template thereof of good heat-transfer.
Asymmetric plate type heat exchanger is identical with symmetric form plate type heat exchanger basic structure, and promptly folded mutually by plate, periphery and hole, angle constitute alternate cold and hot fluid passage by rubber ring seal.Main points of the present utility model are that the channel cross-sectional area of heat exchanger both sides does not wait, promptly asymmetric, the surface that constitutes the used plate of passage has special geometry bellows-shaped, and the geometry of adjacent plate and relative position thereof are not all the asymmetric plate type heat exchanger that feature is formed.Novel plate provided by the utility model, its surface adopt sine bellows to constitute basic waveform of runner, get large and small sine wave simultaneously again and alternately occur, the oppositely stacked mutually and structure that forward stacks of its adjacent plate waveform, the asymmetry of realization passage.
Fig. 1 is the corrugated cardboard sheet of symmetric form plate type heat exchanger and the cross section of fluid channel schematic diagram of formation thereof.
Fig. 2 is the cross section of fluid channel schematic diagram that the corrugated cardboard sheet of asymmetric plate type heat exchanger constitutes.
Fig. 3 is the corrugated cardboard sheet floor map.
Hole, 1-angle among the figure, 2-settles the groove of seal washer, 3-ripple, A-major path, B-passage aisle, beta waves line inclination angle.
Embodiment: the external waviness pattern is sine bellows and gets big or small sine bellows alternately, and the ripple angle of inclination beta is 30 degree, and the ripple pitch is 20mm, the ripple degree of depth, (little) is 4(1.5 greatly) mm, asymmetric area ratio, promptly major path sectional area and passage aisle sectional area ratio are 1.56:1.By above-mentioned form is the asymmetric plate type heat exchanger that plate that the stainless steel of 0.8mm is made builds up mutually with thickness, as shown in Figure 2, is oppositely stacked by the plate waveform and to constitute major path A, and waveform phase synperiplanar is put and constituted passage aisle B.Flow velocity is 1M/S in both sides, and the hot side of fluid mean temperature is 50 ℃ (major path A), and cold side (passage aisle B) temperature is 20 ℃, when flow process length is 1.050M, and coefficient of heat transfer K=4558W/m
2℃.△ P falls in hot side pressure this moment
H=0.27at, △ P falls in cold side pressure
C=0.55at.But calculate as if hot lateral pressure being fallen bring up to by equipressure, then the flow velocity of major path side can improve about 2.8 times, and this moment, the convection transfer rate of hot side also can improve 1 times, and the heat transfer coefficient of heat exchanger can be brought up to 5600W/m accordingly
2About ℃.And for symmetric form as the BR-20A heat exchanger, under the essentially identical property of coefficient of heat transfer condition, its pressure falls and can reach 0.75～0.8at, (0.55at) exceeds 50% than asymmetric passage.
This shows, under identical situation, asymmetric heat exchanger, its coefficient of heat transfer is big, and resistance drop is little.And by test as can be known, asymmetric heat exchanger is with the increase of flow, and the comprehensive heat exchange index J/f of its passage coefficient of friction and convection transfer rate also improves significantly.Because the design feature of new template when high flow capacity, can fully show the superiority of its performance especially more.In addition, for fouling and antiseptic property aspect, because the distance between plates of plate type heat exchanger is little, runner is narrow, so to having very easily foulings such as sand grain material, chemical industry fluid and GEOTHERMAL WATER, very cause runner and stop up.Common liquid-liquid plate heat exchanger all is a symmetric channel, can't solve such as the narrow problem of GEOTHERMAL WATER side runner, and adopt asymmetric passage, just can make cooling water side under the good mobile and heat transfer situation of maintenance, GEOTHERMAL WATER or chemical industry fluid side then have the passage of broad, and making flows unimpeded and delay corrodes.
Asymmetric plate-type heat exchanger, than existing general symmetric form plate type heat exchanger, when being used for the strong liquid of fouling tendency-liquid heat exchange situation and both sides fluid flow when differing big, have and conduct heat and the advantage of the good combination property of resistance drop, be a kind of new template plate type heat exchanger of using future that has.
