Technical field
The present invention relates to a kind of heat exchanger plate, it is made by metallic plate and is used in combination with the heat exchanger plate of other same structures, makes them make up abreast and becomes as a whole mutually, forms a heat exchanger.Particularly, the present invention relates to a kind of heat exchanger that makes and form the heat exchanger plate of assembled state integrally, in this heat exchanger, between the heat-exchange fluid under the identical heat transfer condition, can carry out corresponding heat exchange, heat-exchange fluid is flowed reposefully along the facing surfaces of this heat exchanger plate respectively, thereby improve heat exchanger effectiveness.
Background technology
Use between high temperature fluid and cryogen the heat exchanger of conduct heat (being heat exchange) to increase heat transfer coefficient if desired,, then use heat-exchangers of the plate type traditionally widely to improve heat exchanger effectiveness.The structure of this heat-exchangers of the plate type is with the interval parallel to each other placement of polylith heat transfer plate with regulation, forms passage, and passage separates with corresponding heat transfer plate again.High temperature fluid and cryogen alternately flow in above-mentioned passage, carry out heat exchange by this corresponding heat transfer plate.An example of Japanese patent gazette H3-91695 number this common heat-exchangers of the plate type of explanation.
In this common heat-exchangers of the plate type, the gasket seal spare of being made by elastomeric material is placed between two blocks of adjacent plates, makes their the constant and formation fluid passage of fixed distance.Yet the high pressure of the heat-exchange fluid that flows between this plate can make the distortion of sealing spacer elements, thereby can not guarantee fluid is separated or causes the variation of the distance between the plate.In this case, the heat exchange that can not imitate throws into question.Consider this situation, there is a problem in this common heat exchanger, promptly can only use heat-exchange fluid in the pressure limit that the sealing spacer elements can be born.
Recently proposed a kind of heat exchanger, its structure is, will be with predetermined interval placed metal thin plate, on the relative side of respective plate,, this plate is assembled into parts by its end is welded together, need not any gasket seal spare, form the passage of heat-exchange fluid.An example as this invention that bright person did, Japanese patent gazette 2003-194490 number a kind of heat-exchanging part has been described, the heat transfer plate aligning of making by sheet metal parallel to each other wherein, and it is spaced-apart, these plates are except a side, and its periphery is welded into a unified body with an opening.This opening then covers with an end plate.
Usually and widely the irregular pattern with the L font is added on the heat transfer plate of heat-exchangers of the plate type.Yet this irregular pattern can not reach reducing of the pressure loss and guarantee balance to the resistance of pressure.Therefore, various irregular pattern has been proposed.An example of this different irregular pattern has been described for Japanese patent gazette 2000-257488 number.
The structure of the plate of above-mentioned common heat exchanger is, this plate comprises a plurality of heat transfer parts, the top of each heat transfer part has a knoll shape, and it has a flat (being the cross section of plate) at the thickness direction of this plate, and is rectangle in the plane of plate.These plates make up mutually, and a plate is placed on and forms a heat exchanger on another piece plate.
This common heat exchanger (being heat-exchanging part) have at Japanese patent gazette H3-91695 the structure of recording and narrating among 2003-194490 and the 2000-257488.The common plate that irregular pattern is arranged described in Japanese patent gazette 2000-257499 number also can be used on the plate described in Japanese patent gazette H13-91685 and 2003-194490 number, these plates stack mutually to form heat exchanger, make plate alternately put upside down and the upper part, heat transfer part of this plate towards the flow channel intersection of adjacent plate.These plates make up mutually, make the heat transfer part outstanding in identical direction, the result was though should rotate 180 ° by plate alternately, between two blocks of adjacent plates, form flow channel and have identical pattern, this can cause with the vertical direction of the combinations of directions of plate on opposite position relation.
When will this common heat exchanger plate being placed on another piece, lead into the identical structure of flow channel with one of identical orientation.Yet the plate that has the irregular pattern opposite with upper surface is located on the lower surface, and this causes the symmetrical configuration on the facing surfaces of this plate.Therefore, identical heat transfer condition can not given and fluid on the facing surfaces of heat exchanger plate, keep identical thereby can not correspondingly handle, to guarantee the problem of the enough heat transfer coefficients between the heat-exchange fluid in the facing surfaces of this plate and the heat transfer state between the corresponding fluid.
Even when the apparent surface's of this plate shape differs from one another, the characteristic of this shape and the corresponding heat-exchange fluid that contacts with the respective surfaces of this plate or with the coupling of its flow regime, can improve the heat transfer coefficient between this plate and the corresponding fluids independently, even so that under the situation mutually inequality of the heat transfer state on the apparent surface of this plate, total can improve between the fluid heat transfer efficiency.Yet the shape of corresponding plate is that certain flow regime of each fluid is stipulated.When expection causes by the gap between this plate as the relation of the position between the plate of the use of heat exchanger or this heat exchanger, the change of flow of heat exchange fluid condition, in the time of maybe will changing fluid itself, heat transfer property may depart from optimum point, thereby causes performance severe exacerbation and total versatility variation.

According to the matrix structure on the upper surface of this plate, the ledge 11 of irregular pattern on mutually perpendicular two directions with predetermined spaced-apart alignment.The shape of each ledge 11 is identical, all has the outer periphery surface of the bending of revolution symmetry.Each ledge 11 extends to other four adjacent ledges of the ledge 11 before surrounding.This ledge 11 has the top 11a of flat area of a circle shape and is different from remaining outer periphery surface of top 11a.This outer periphery surface has the truncated cone of expanding from this top 11a downwards.
The inner periphery surface of the outer periphery surface of this ledge 11 and this recess 12 is sine wave shape on the cross section of this metallic plate.On the diagonal of this metallic plate, with the rectangular configuration continuity, wherein, this ledge 11 and this recess 12 replace these two periphery surfaces at regular intervals respectively.Each ledge 11 has the curved surface that forms by with 12 ledge 11 smooth connections adjacent with another of adjacent recess.The inner periphery surface of each recess 12 has the identical shaped part of the outer periphery surface that extends to adjacent ledge 11.In addition, the inner periphery surface of recess 12 extends to 4 adjacent recesses 12 smoothly.This recess 12 has the surface of this continuity, to form the shape of revolution symmetry.
A core between core between immediate adjacent two ledges 11 and immediate adjacent two recesses 12 is the transition sweep 13 that is used for connecting smoothly adjacent curved surface.Intermediate altitude between the top of the transition sweep 13 of this transition curved surface and the bottom of recess 12 and ledge 11 is on equal height.The outer periphery surface of this ledge 11 directly extends to the inner periphery surface of this recess 12 smoothly.This ledge 11 and recess 12 extend to other immediate adjacent ledge 11 and recesses 12 by this transition sweep 13 respectively.The structure of this bending can make the power that is added on this plate disperse, thereby gains in strength, to adapt to the fluid with high pressure and to improve crystallized ability.
In heat exchanger plate 10 of the present invention, on another (being the bottom) surface of this metallic plate, this recess 12 has the structure identical with ledge 11, and on the surface of this metallic plate, this ledge 11 has the structure identical with this recess 12, so has identical irregular pattern on the facing surfaces of this metallic plate.
According to the matrix structure on heat exchanger plate 10, the straight line that ledge 11 and recess 12 are aimed at along it, with respect to the corresponding side inclination 45 of the plate of rectangle, the result, this ledge 11 is just in time parallel or vertical with the corresponding side of this plate along the diagonal that it replaces with recess 12.
Above-mentioned heat exchanger plate 10 is placed on another piece heat exchanger plate with same structure, make they on phase the same side mutually towards, and the top 11a of the ledge 11 of previous plate is contacted with the respective tops of back one ledge, form a combiner, the combiner that will form like this makes up with other combiners in the same way then, forms a heat exchanger with gap (being passage).Heat-exchange fluid flows in these passages, make with these fluids that the upper surface of this plate contacts in a kind of, with these fluids that the lower surface of this plate contacts in another kind carry out heat exchange.This plate utilizes this method to be combined into an integral body mutually, this ledge is contacted with each other, to gain in strength.As a result, even the pressure of increasing between this plate, this heat exchanger is not easy distortion.Like this, the variable in distance between this plate can be prevented, thereby the big situation of pressure difference between the heat-exchange fluid can be tackled.
In the gap 14 that forms between two blocks of adjacent plates of the plate that makes up like this, the top 11a of the ledge 11 of this plate contacts with the top 11a of the ledge 11 of another piece plate.At this moment, except the top 11a of contact, the corresponding outer periphery surface of the ledge 11 of these plates 10 mutually and to, keeping predetermined distance between them; The corresponding transition sweep 13 of these plates 10 mutually towards, between them, keep predetermined distance.Hold predetermined distance with the bending of this filtration of aspect ratio.The gap that forms between the corresponding outer periphery surface of ledge 12 is communicated with the gap that forms between corresponding recess 12, to form a straight passage.In this passage, the flow channel area between the corresponding recess 12 is bigger than the flow channel area between the corresponding ledge 12, makes this passages extend, and the while is repeatedly expanded and reduces.This passage and other passages intersect, and are communicated with it, form a kind of long-pending channel design (see figure 9) of compiling like this.
On the other hand, in the gap 15 that on an opposite side, forms with respect to this plate, identical irregular pattern forms identical structure, the result, this passages ground extends, and repeatedly expand simultaneously and reduce, and this passage is crossing with other passages, be communicated with it, form the channel design (see figure 10) of braiding same as described above like this.When the heat exchanger that is made of the plate with the said method combination comes into operation, make a side level or vertical placement the in two sides of each piece plate, main thoroughfare then, promptly each all remains on heeling condition by the gap that the sweep 13 of corresponding recess 12 that replaces and transition forms.According to identical irregular pattern, have the irregular pattern opposite on the lower surface of this plate with upper surface, make at the ledge on the upper surface of this plate corresponding to the recess on this plate lower surface.These plates on phase the same side one be placed on another, the position skew that causes ledge and recess between them apart from half of length.Except this point,, keep identical condition for each gap between this plate.
The following describes the work of the heat exchanger that constitutes by heat exchanger plate 10 according to an embodiment of the invention now.On the one hand, by with a kind of the introducing in the gap 14 that forms between two blocks of adjacent plates that are parallel to each other and combine of these parts in these fluids, and discharge this fluid from this gap; On the other hand, in the gap 15 that forms between two adjacent plates that the another kind in these fluids are introduced in these parts, and discharge this fluid, and between two kinds of heat-exchange fluids, carry out heat exchange from this gap.
By the gap 14,15 that the structure of this ledge 11 forms between this plate, on the straight line that this ledge 11 is aimed at along its, extend continuously and linearly, form channel part, this channel part and another channel part are intersected, be communicated with, thereby form a channel design of braiding with it.When respectively in the gap 14, the flowing relation of the heat-exchange fluid that flows in 15 is based on the PARALLEL FLOW system, during any one of reverse flow system and cross flow system, this heat-exchange fluid is flowed in substantially the same mode, form substantially the same heat transfer property.In addition, when heat-exchange fluid flows according to any combination of flow direction, can reduce the pressure loss in this passage, guarantee the smooth flow in gap 14,15, thereby can carry out effective heat exchange.
Under the sample situation of heat-exchange fluid according to the reverse flow system flow, between two blocks of compoboard adjacent plates, form in the gap 14, form the passage that flows of a braiding, this braiding passage mainly is included between the respective recess 12 with minimum ledge height and has between the corresponding transition sweep 13 of middle ledge height, along the channel part that the straight line inclination of this ledge 11 and recess 12 alignings is extended, make this heat-exchange fluid flow at this braiding flow channel.On the other hand, in another gap 15 that between two adjacent panels of this compoboard, forms, the flow channel of braiding mainly be included between the respective recess 12 that forms on the back side of this ledge 11 and corresponding transition sweep 13 between, along the channel part that straight line tilts to extend, make another kind of heat-exchange fluid in this braiding flow channel, flow.As a result, introduce heat-exchange fluid in this compoboard, on the facing surfaces of this heat exchanger plate 10, flow on the incline direction respectively, repeat diversity and the property converged simultaneously, scatter in each zone of this plate reposefully.
Because, heat-exchange fluid is scattered on the entire area of this plate for the ease of between heat-exchange fluid, conducting heat and improving rate of heat exchange.In addition, heat-exchange fluid flows in having the braiding flow channel of the special shape that can make this flow of heat exchange fluid respectively, repeats its diversity and the property converged simultaneously, and the heat transfer property of the characteristic that meets the heat-exchange fluid on the apparent surface of this plate is arranged.As a result, consider above-mentioned characteristic,, can carry out effectively, thereby can improve heat exchanger effectiveness between the fluid significantly by the identical gap 14,15 and the heat transfer of crossing between the heat-exchange fluid of heat transfer plate 10 according to irregular pattern.
In heat exchanger plate according to an embodiment of the invention, according to identical irregular pattern, this heat exchanger plate 10 is set on the irregular pattern lower surface opposite with upper surface, makes at the ledge on the upper surface of this plate corresponding to the recess on the lower surface at this plate.On another piece plate on this plate placement same side, the top 11a of the ledge 11 of last block of plate is contacted with the top 11a of the ledge 11 of a back plate, with repeat this combination, when forming a combiner, provide corresponding to the structure of the plate of the recess on the lower surface at this plate 12 at the ledge on the upper surface of this plate 11 to have a passage of respective shapes between this plate.Therefore, can will give and pass through the heat-transfer fluid in the gap 14,15 between this plate at the identical heat transfer environment on the apparent surface of this plate.Therefore, between by the fluid of this plate, can suitably conduct heat, can not be subjected to the influence of flow regime He its characteristic of fluid, thereby can between heat-exchange fluid, carry out effective heat exchange.In addition, extend on the straight line of its aligning linearly at this ledge and recess in the gap between this plate, and the while repeatedly expands and reduces, form channel part, make this channel part and another channel part intersect, be communicated with, thereby form the channel design that weaves with it.Even when the flowing relation of heat-exchange fluid is based on the PARALLEL FLOW system, during in the reverse flow system cross flow system any one, heat-exchange fluid is flowed basically in an identical manner, to form identical heat transfer property basically.In addition, when this heat-exchange fluid flows according to any combination of flow direction, heat exchange is carried out reposefully, the pressure loss is little and can improve the free degree that designs heat exchanger, thereby makes versatility fine.
