Association request it is cross-referenced
The application advocates the priority of Japan's patent application 2013-74892, Japan patent application 2013- The content of No. 74892 is written into the record of present specification by quoting.
Technical field
Heat-exchangers of the plate type the present invention relates to be used as evaporator and condenser.
Background technology
All the time, heat-exchangers of the plate type is used for evaporator and condenser, the evaporator, companion more as heat exchanger First fluid is evaporated with the heat exchange of first fluid and second fluid, the condenser, with first fluid and second The heat exchange of body and make first fluid condense (for example, referring to patent document 1).
In general, as shown in fig. 6, heat-exchangers of the plate type has main part 3, the main part 3 includes multiple heat transfer plates 2. Main part 3 has：First flow path 30；Second flow path 31；A pair first access 32,33；A pair second access 34,35.The One stream 30 makes first fluid A circulate.Second flow path 31 makes second fluid B circulate.A pair first access 32,33 with it is first-class Road 30 connects, and first fluid A flowed into the first flow path 30, flowed out.A pair second access 34,35 and second flow path 31 Connection, makes second fluid B be flowed into the second flow path 31, flowed out.
It is further elaborated with.Multiple heat transfer plates 2 have at least four openings (not numbering) respectively.And, in main part 3 Lamination has multiple heat transfer plates 2.Thus, make the first flow path 30 that first fluid A circulates for boundary is alternatively formed and make with heat transfer plate 2 The second flow path 31 of second fluid B circulations.Further, since multiple heat transfer plates 2 are by lamination, so, it is formed in opening on heat transfer plate 2 Mouth is connected on the lamination direction of multiple heat transfer plates 2.Thus, first fluid A is made to flow into the first company of the side of first flow path 30 Path 32, the first access 33 for making the opposite side that first fluid A flows out from first flow path 30, second fluid B is set to flow into second Second access 34 of the side of stream 31, the second access 35 for making the opposite side that second fluid B flows out from second flow path 31 Through heat transfer plate 2, and upwardly extended (for example, referring to patent document 1) in the lamination side of multiple heat transfer plates 2.
In this heat-exchangers of the plate type 1, the first fluid A supplied to first access 32 of side passes through first flow path 30 flow out to the first access 33 of opposite side.In addition, passing through second to the second fluid B that second access 34 of side is supplied Stream 31 flows out to the second access 35 of opposite side.And, in heat-exchangers of the plate type 1, as described above, first fluid A exists Circulated in first flow path 30, and second fluid B circulates in second flow path 31.Thus, heat-exchangers of the plate type 1 is via separation first The larger heat-transfer area of the heat transfer plate 2 of stream 30 and second flow path 31 and first fluid A and second fluid B is carried out heat exchange.
Therefore, in this heat-exchangers of the plate type 1, the quantity of the heat transfer plate 2 of lamination is more, and heat exchange is made contributions Heat transfer area is bigger, can more improve heat exchange performance.
But, if the quantity of heat transfer plate 2 increases, with the quantity of the heat transfer plate 2 of lamination correspondingly, in the product of heat transfer plate 2 The first access 32,33 and the length of the second access 34,35 that layer side upwardly extends are also elongated.
That is, a pair first access 32,33 and a pair second access are respectively formed with because the opening of heat transfer plate 2 is connected 34th, 35, therefore, if the increasing number of the heat transfer plate 2 of lamination, a pair first access 32,33 and a pair second access 34, 35 respective flow path length also can correspondingly increase with the quantity.
As a result, in making the first access (the first access of side) 32 that first fluid A flows into first flow path 30 The circulating resistance of first fluid A becomes big, and first fluid A becomes to be difficult to circulate.Therefore, in this heat-exchangers of the plate type 1, one Influxs of the first fluid A of the entrance side of the first access 32 of side to first flow path 30 and the first access 32 in side The first fluid A of end side become uneven to the influx of first flow path 30.That is, in this heat-exchangers of the plate type 1, first Fluid A can produce inequality to the distribution of the multiple first flow path 30 on the lamination direction of heat transfer plate 2 side by side.Its result is, In this heat-exchangers of the plate type 1, even if increasing the quantity (even if increasing the quantity of first flow path 30) of heat transfer plate 2, heat is being improved Switching performance (volatility) aspect there is also boundary.

Thus, in each first community section B1a, B2a and second community section B1b, B2b, the stream of first fluid A is by most inner side first Stream 30, the first link road 37a, middle first flow path 30, the second link road 37b and outermost first flow path 30 and with complications Mode formed.
In main part 3, the first inflow access 32 of present embodiment is extended to be located at from one end of first direction and is somebody's turn to do The benchmark stream Ra of the middle section of first direction, and only connected with benchmark stream Ra.
It is only small with first and the first outflow access 33 extends to the other end in main part 3 from one end of first direction Each outermost first flow path 30 of section B1a, B2a and second community section B1b, B2b is connected.I.e., in the present embodiment, first The terminal of the stream of the first fluid A in macroportion B1 and the second macroportion B2 (is communicated with each other and with base by first flow path 30 Quasi- stream Ra be starting point formed first fluid A stream terminal) for first community section B1a, B2a and second community section B1b, Each outermost first flow path 30 of B2b.
So, the outflow access 33 of each outermost first flow path 30 and first of the first macroportion B1 and the second macroportion B2 Connection.Therefore, in each first macroportion B1 and the second macroportion B2 in the heat-exchangers of the plate type 1 of present embodiment, first The stream of fluid A is formed between the first inflow outflow access 33 of access 32 and first in the way of complications.And, formed The zigzag path of the first fluid A in the first macroportion B1 is (with a branch of the side in a side of first direction Road 36a is the stream of the first fluid A of starting point) and the first fluid A that is formed in the second macroportion B2 zigzag path (with Branch path 36b of the opposite side in the another side of first direction is the stream of the first fluid A of starting point) with benchmark stream It is asymmetrically formed on the basis of Ra.
And the one end of the second inflow outflow access 35 of access 34 and second respectively from the main part 3 in first direction is prolonged Reach the other end.Multiple second flow paths 31 are connected with the second inflow outflow access 35 of access 34 and second respectively.Phase therewith With ground, the stream of second fluid B is formed as the crow flies between the second inflow outflow access 35 of access 34 and second.Additionally, In the present embodiment, the stream of the second fluid B being formed in the first macroportion B1 and it is formed in the second macroportion B2 The stream of second fluid B is symmetrical on the basis of the middle section of first direction.
Therefore, in the heat-exchangers of the plate type 1 of present embodiment, the stream of first fluid A flows into access with first 32 and first tortuous mode between outflow access 33 constitute.And the stream of second fluid B flows into the He of access 34 second Constituted as the crow flies between second outflow access 35.
As described above, the heat-exchangers of the plate type 1 of present embodiment has main part 3, the main part 3 includes many of lamination Individual heat transfer plate 2.Main part 3 has：The first flow path 30 for making first fluid A circulate；The second flow path for making second fluid B circulate 31；The the first inflow access 32 for connect and make first fluid A to be flowed into relative to first flow path 30 with first flow path 30, flowing out And first outflow access 33；Connect and make the second fluid B flowed into relative to second flow path 31 with second flow path 31, flow out Second flows into the outflow access 35 of access 34 and second.And, first flow path 30 and second flow path 31 are boundary's friendship with heat transfer plate 2 Alternately formed.In addition, first flows into the outflow inflow outflow of access 34 and second of access 33, second of access 32, first company Path 35 extends through heat transfer plate 2 and extends in a first direction.
And, in the heat-exchangers of the plate type 1 of present embodiment, positioned at least one first of the middle section of first direction Stream 30 is the benchmark stream Ra of the branch location of the stream in first fluid A.Main part 3 has at least one pair of branch Road 36a, 36a, branch path 36a, 36a make benchmark stream Ra and are located at the first macroportion B1 and the second macroportion B2 respectively The first flow path 30 of (the ratio benchmark stream Ra on first direction leans on a side and the another side of first direction) is connected.It is first-class Enter access 32 only to be connected with benchmark stream Ra.In addition, the first outflow access 33 is only connected with following first flow path 30, this One stream 30 is located at the first macroportion B1 and the second macroportion B2, and (the ratio benchmark stream Ra on first direction is by the one of first direction Side and another side), and communicated with each other by first flow path 30 and turn into benchmark stream Ra as starting point formed it is first-class The terminal of the stream of body A.And, the first macroportion B1 (the ratio benchmark stream Ra on first direction leans on a side of first direction) In the first fluid A with a branch path 36a of side as starting point stream and the second macroportion B2 (ratios on first direction Another sides of the benchmark stream Ra by first direction) in first fluid A with a branch path 36a of opposite side as starting point Stream is asymmetrically formed using benchmark stream Ra as benchmark.
Therefore, the heat-exchangers of the plate type 1 according to present embodiment, first flow into access 32 only with positioned at first direction Benchmark stream Ra (first flow path 30) connection of middle section (being the center of middle section in present embodiment).So, due to First inflow access 32 only forms the middle section (being the center of middle section in present embodiment) to first direction, institute So that the increase of the pressure loss of first fluid A in the first inflow access 32 can be suppressed.
And, a pair one time branch path 36a, 36a makes benchmark stream Ra and is located at the first macroportion B1 and second largest respectively The first flow path 30 of section B2 (the ratio benchmark stream Ra on first direction leans on a side and the another side of first direction) is connected. Therefore, in main part 3, as the stream of first fluid A, it is formed with once dividing including the side that is connected with benchmark stream Ra The system of branch road 36a and the system of branch path 36a the two systems including the opposite side that is connected with benchmark stream Ra.
Therefore, first fluid A is (every individual from the length of the first stream for flowing into the outflow access 33 of access 32 to the first The stream of system is long) shorten.Thus, in the heat-exchangers of the plate type 1 of said structure, first fluid A can be suppressed in whole stream In the pressure loss increase, heat exchange performance higher can be obtained.
Especially, in the heat-exchangers of the plate type 1 of present embodiment, the first macroportion B1 (ratio reference flows on first direction A sides of the road Ra by first direction) in the stream of first fluid A with a branch path 36a of side as starting point and second largest With a branch path 36a of opposite side in section B2 (the ratio benchmark stream Ra on first direction leans on the another side of first direction) For the stream of the first fluid A of starting point is asymmetrically formed on the basis of benchmark stream Ra.Therefore, the first macroportion B1 (first party Upward ratio benchmark stream Ra by first direction a side) in from first flow into access 32 to the first outflow access 33 First fluid A circulation status and circulation distance and the second macroportion B2 (the ratio benchmark stream Ra on first direction leans on first The another side in direction) in from first flow into access 32 to the first outflow access 33 first fluid A circulation status And circulation is apart from identical.Thus, first fluid A equably circulates in all multiples first flow path 30 in main part 3. Therefore, in the heat-exchangers of the plate type 1 of said structure, first fluid A and second fluid B can be made effectively in main part 3 Carry out heat exchange.
In addition, in present embodiment, respectively in the first macroportion B1 and the second macroportion B2 (ratio benchmark on first direction A sides and another side of the stream Ra by first direction) more than three first flow path 30 of middle setting.And, in each first great Qu In section B1 and the second macroportion B2, the first flow path of the middle section positioned at first direction in the first flow path 30 of more than three The middle benchmark stream Rb of 30 branch locations for turning into the stream in first fluid A.In addition, main part 3 has at least one pair of Secondary branch path 36b, 36b, a pair two times branch paths 36b, 36b make middle benchmark stream Rb and are located at first community section respectively (benchmark stream Rb is by first direction in the middle of the ratio in main part 3 on first direction for B1a, B2a and second community section B1b, B2b The position of one side and the position of another side) first flow path 30 connect.Each branch path 36a, 36a be located at the respectively (the ratio benchmark stream Ra on first direction leans on a side and the other end of first direction for one macroportion B1 and the second macroportion B2 Side) middle benchmark stream Rb connection.And, (benchmark stream Rb is leaned in the middle of the ratio on first direction for first community section B1a, B2a One side of first direction) in the first fluid A with the secondary branch path 36b of side as starting point stream and second community section Secondary point with opposite side in B1b, B2b (another sides of the benchmark stream Rb by first direction in the middle of the ratio on first direction) Branch road 36b is asymmetrically formed for the stream of the first fluid A of starting point on the basis of middle benchmark stream Rb.
Therefore, branch path 36a, 36a is in each first macroportion B1 and the second macroportion B2 (ratio bases on first direction A sides and another side of the quasi- stream Ra by first direction) in, only with the middle section (present embodiment positioned at first direction In for middle section center) middle benchmark stream Rb (first flow path 30) connect.Thus, in each first macroportion B1 and In two macroportion B2 (the ratio benchmark stream Ra on first direction leans on a side and the another side of first direction), a branch path 36a, 36a only form the middle section (being the center of middle section in present embodiment) in first direction.Therefore, it is possible to press down The increase of the pressure loss of first fluid A in branch path 36a, 36a of system.And, in each first macroportion B1 of main part 3 And in the second macroportion B2 (side and another side of ratio benchmark stream Ra on first direction by first direction), as the The stream of one fluid A, be formed with the secondary branch path 36b including the side connected with middle benchmark stream Rb system and including The system of secondary branch path 36b of the opposite side connected with middle benchmark stream Rb the two systems.Therefore, in main part 3 In each first macroportion B1 and the second macroportion B2, from the first fluid A's of branch path 36a to first outflow access 33 The length (stream of each system is long) of stream shortens.Thus, in the heat-exchangers of the plate type 1 of said structure, can be suppressed The increase of the pressure losses of the one fluid A in whole stream, can obtain heat exchange performance higher.
(the one end of benchmark stream Rb by first direction in the middle of ratio on first direction in addition, first community section B1a, B2a Side) in the first fluid A with the secondary branch path 36b of side as starting point stream and second community section B1b, B2b (first party Another sides of the benchmark stream Rb by first direction in the middle of upward ratio) in the secondary branch path 36b with opposite side as starting point The stream of first fluid A be asymmetrically formed on the basis of middle benchmark stream Rb.Therefore, from first community section B1a, B2a (the A sides of the benchmark stream Rb by first direction in the middle of ratio on one direction) in side secondary branch path 36b to first-class Go out the first fluid A of access 33 circulation status and circulation distance and from second community section B1b, B2b (ratio on first direction Middle benchmark stream Rb by first direction another side) in opposite side secondary branch path 36b to first outflow access The circulation status of 33 first fluid A and circulation are apart from identical.Thus, even if the quantity increasing of the heat transfer plate 2 that main part 3 is included Many, in all multiples first flow path 30 in main part 3, first fluid A also can uniformly circulate.Therefore, upper State in the heat-exchangers of the plate type 1 of structure, in main part 3 first fluid A and second fluid B can be made effectively to carry out hot friendship Change.
Especially, first flow path 30 is respectively provided with equal number in the first macroportion B1 and the second macroportion B2.In addition, (benchmark stream Rb leans on first direction in the middle of the ratio on first direction for each first community section B1a, B2a and second community section B1b, B2b A side and another side) in the first flow path 30 of two or more and equal number is set.In addition, main part 3 is each first Have respectively in macroportion B1 and the second macroportion B2 and be pointed to first community section B1a, B2a (ratio intermediate base on first direction A sides of the quasi- stream Rb by first direction) more than two first flow path 30 link road 37a, 37b for being attached.Separately Outward, with second community section B1b, B2b is pointed to, (benchmark stream Rb leans on first direction to main part 3 in the middle of the ratio on first direction Another side) more than two first flow path 30 link road 37a, 37b for being attached.Gain the first rank the stream of body A Terminal first flow path 30 to be located at first community section B1a, B2a and second community section B1b, B2b (on first direction respectively Than middle benchmark stream Rb by first direction a side and another side) first flow path 30, the first flow path 30 and first Outflow access 33 is connected.Stream thereby, it is possible to not make first fluid A expands heat transfer area with increasing.
In addition, in present embodiment, the stream Ra on the basis of a first flow path 30 of the middle section of first direction. And, the first inflow access 32 is only connected with a benchmark stream Ra.Thus, the most upstream of the stream of first fluid A point Branch position (benchmark stream Ra) is one, first fluid A sides respectively to the main part 3 in first direction and another side It is uniformly distributed.Therefore, the position circulation at the position and another side of a side of the main part 3 in distinguishing in a first direction First fluid A become uniform, first fluid A and second fluid B effectively carry out heat exchange in whole main part 3.
In addition, in the first macroportion B1 and the second macroportion B2, (the ratio benchmark stream Ra on first direction leans on first direction A side and another side) in be respectively provided with two or more first flow path 30.Main part 3 has to be made to be located at the first macroportion B1 More than two first flow path 30,30 in (the ratio benchmark stream Ra on first direction leans on a side of first direction) connect each other Logical link road 37a, 37b (the first link road 37a and the second link road 37b).In addition, main part 3 have make to be located at it is second largest More than two first flow path 30 in section B2 (another side of ratio benchmark stream Ra on first direction by first direction), 30 link road 37a, 37b for communicating with each other (the first link road 37a and the second link road 37b).Thus, from a branch path 36a The first fluid A of inflow is sequentially flowing and to be flowed in each first flow path 30 in first flow path 30 on first direction side by side It is logical.Therefore, the first fluid A respectively sides and another side of ratio benchmark stream Ra in a first direction by first direction Equably circulated in more than two each first flow path 30.
Especially, in the present embodiment, in the first macroportion B1 and the second macroportion B2 (ratio reference flows on first direction A sides and another side of the road Ra by first direction) it is respectively provided with more than three first flow path 30.In addition, main part 3 is (the ratio benchmark stream Ra on first direction leans on a side and the other end of first direction for one macroportion B1 and the second macroportion B2 Side) have respectively and adjacent first flow path 30,30 is communicated with each other and set two of diverse location in a first direction connections Road 37a, 37b.The first flow path 30 that the two link roads 37a, 37b are respectively relative to be connected with the link road 37a, 37b connects Logical other link road 37a, 37b configure different positions in second direction (direction orthogonal from first direction).
Thus, the heat-exchangers of the plate type 1 of present embodiment, makes the first flow path 30 that the circulating direction of first fluid A is different Alternately configured in each first macroportion B1 and the second macroportion B2 that (the ratio benchmark stream Ra on first direction leans on first direction A side and another side) in.That is, because the configuration of link road 37a, 37b of diverse location on first direction is different, In each first macroportion B1 and the second macroportion B2, (ratio benchmark stream Ra on first direction is by a side of first direction and another One side) in, first fluid A flowing (complications) and the outflow access 33 of arrival first while circulating direction is changed.
Therefore, the first fluid A and the heat of the second fluid B circulated in second flow path 31 for being circulated in first flow path 30 The mode (timing of heat transfer) of exchange is different according to the configuration of first flow path 30, therefore, first fluid A connects from the first inflow The outflow access 33 of path 32 to the first is reliably used for heat exchange.Thereby, it is possible to pass through whole main part 3, (each first is big (the ratio benchmark stream Ra on first direction leans on position and the other end of a side of first direction for section B1 and the second macroportion B2 The position of side)) obtain heat exchange performance higher.
Additionally, heat-exchangers of the plate type of the invention is not limited to above-mentioned implementation method, the model of purport of the invention is not being departed from Enclose interior can suitably be changed certainly.
In above-mentioned implementation method, the first macroportion B1 and the second macroportion B2 quilts on the basis of middle benchmark stream Rb respectively It is distinguished into two away minor segments (first community section and second community section) B1a, B2a, B1b, B2b, but not limited to this.For example, may be used also Think, respectively in the first macroportion B1 and the second macroportion B2 of the both sides of reference flow road Ra, whole first flow path 30 All directly connected with the first outflow access 33.
In above-mentioned implementation method, the first macroportion B1 and the second macroportion B2 quilts on the basis of middle benchmark stream Rb respectively It is distinguished into two away minor segments (first community section and second community section) B1a, B2a, B1b, B2b, but not limited to this.For example, such as Fig. 4 It is shown, msy be also constructed to, in addition to benchmark stream Ra, main part 3 is in each first macroportion B1 and the second macroportion B2 ( Ratio benchmark stream Ra on one direction leans on a side and the other end of first direction) there are more than two first flow path respectively 30, also, with the link road 37c for making adjacent first flow path 30,30 in more than two first flow path 30 communicate with each other, 37d、37e、37f、37g.So, from a first fluid A for branch path 36a inflows in multiple first in the first direction side by side Sequentially moved in stream 30 and circulated in each first flow path 30.Therefore, the first macroportion B1 and second largest area are being located at respectively In section B2 (side and another side of ratio benchmark stream Ra on first direction by first direction) more than two each the In one stream 30, first fluid A can be made equably to circulate.
In this case, as shown in figure 4, main part 3 has three respectively in each first macroportion B1 and the second macroportion B2 First flow path 30 more than individual.In addition, main part 3 has and making adjacent first flow path 30,30 communicate with each other and being located at first party To diverse location on more than two link road 37c, 37d, 37e, 37f, 37g.And, the link road 37c of more than two, 37d, 37e, 37f, 37g can also respectively be configured in following position：Relative to the link road 37c, 37d, 37e, 37f, 37g Other link road 37c, 37d, 37e, 37f, 37g for the connection of first flow path 30 for being connected, in second direction (with first direction Orthogonal direction) on different position.Additionally, have multiple link road 37c, 37e, 37g in a side of second direction, in addition, In the case where the another side of second direction has multiple link road 37d, 37f, it is preferable that positioned at a side of second direction Multiple link road 37c, 37e, 37g are configured to same column (concentric), multiple link road 37d positioned at the another side of second direction, 37f is configured to same column (concentric).
If so, in each first macroportion B1 and the second macroportion B2, making different many of circulating direction of first fluid A Individual first flow path 30 is alternately arranged.That is, the configuration due to link road 37c, 37d, 37e, 37f, 37g in a first direction is different, So, in each first macroportion B1 and the second macroportion B2, first fluid A change circulating direction while flowing (complications) and Reach first and flow out access 33.
So, the first fluid A and the heat of the second fluid B circulated in second flow path 31 for being circulated in first flow path 30 The mode (timing of heat transfer) of exchange is different according to the configuration of first flow path 30.Therefore, first fluid A from side first Access 32 is reliably used for heat exchange to the first access 33 of opposite side.Thus, in whole main part 3, (each first is big Section B1 and the second macroportion B2) in can obtain heat exchange performance higher.
In above-mentioned implementation method, the stream on the basis of a central first flow path 30 of the middle section of first direction Ra, but not limited to this.For example, as shown in figure 5, the multiple first flow path 30 positioned at the middle section of first direction can respectively all On the basis of stream Ra.In this case, main part 3 has the connection straight line path 38 for making multiple benchmark stream Ra connections.And, side Branch path 36a and the side in outermost two benchmark streams Ra, Ra of multiple benchmark stream Ra benchmark Stream Ra is connected.In addition, a branch path 36a of opposite side and multiple benchmark stream Ra are positioned at outermost two reference flows The benchmark stream Ra connections of the opposite side in road Ra, Ra.And, the first inflow access 32 is connected with multiple benchmark stream Ra.
If so, first fluid A uniformly flows into the middle section positioned at first direction from the first access 32 of side Multiple first flow path 30 (benchmark stream Ra).Therefore, even if the middle section of main part 3 in a first direction, first-class Body A and second fluid B also can effectively carry out heat exchange.In addition, first fluid A is in each first macroportion B1 and second largest area It is distributed evenly in section B2 (side of the main part 3 on first direction and another side), so, respectively in the first great Qu The first fluid A circulated in section B1 and the second macroportion B2 becomes uniform.Thus, first fluid A and second fluid B is entirely leading Heat exchange is efficiently carried out in body portion 3.Though additionally, in this case, there is multiple benchmark stream Ra, in the first macroportion B1 with Branch path 36a of side is once the dividing with opposite side in the stream and the second macroportion B2 of the first fluid A of starting point Branch road 36a (is actually the area comprising multiple benchmark stream Ra for the stream of the first fluid A of starting point with multiple benchmark stream Ra Section Bc in first direction middle section) on the basis of be asymmetrically formed.
In addition, in above-mentioned implementation method, final branch location (the above-mentioned implementation in the circulation path of first fluid A Be middle benchmark stream Rb in mode) downstream, make multiple first flow path 30 via link road 37a, 37b connect, thus, shape Into a stream for system, but not limited to this.For example, as shown in figure 5, respectively in the first macroportion B1 and the second macroportion B2 In, multiple first flow path 30 are distinguished (segmented) by specified quantity in a first direction.And, main part 3 can also be every Individual section B1a, B1b, B2a, B2b have the link road (hereinafter referred to as link road in section) for connecting multiple first flow path 30 37h, 37i, and with make adjacent section B1a, B1b, B2a, B2b each other (first flow path 30,30 is each other) connection it is other Link road (hereinafter referred to as section link road) 37j.
In this case, whole the of a branch path 36a and adjacent section B1b, B2a for being connected with benchmark stream Ra One stream 30 is connected.And, make in the section that the first flow path 30 in section B1b, B2b connects link road 37h relative to once Branch path 36a is configured at spaced intervals in a second direction.
In addition, making the section link road 37j that adjacent section B1a, B1b, B2a, B2b communicates with each other with adjacent Liang Ge areas Link road 37h is continuous in the section of section B1b, B2a of the upstream side in section B1a, B1b, B2a, B2b.And, adjacent two In the section of section B1a, the B2b in the downstream in section B1a, B1b, B2a, B2b link road 37i with make the section B1a, B2b And the section link road 37j of section B1b, B2a connection of upstream side is continuous.
That is, make the section link road 37j that two adjacent sections B1a, B1b, B2a, B2b are connected and adjacent section B1a, Link road 37h, 37i are linearly configuring in each section of B1b, B2a, B2b.Link road 37h, 37i and section are connected in section The configuration of road 37j, even if section increasing number, it is also possible to maintain the relation with adjacent section B1a, B1b, B2a, B2b.
And, respectively in the first macroportion B1 and the second macroportion B2, the terminal of the circulation path of the body A that gains the first rank The first flow path 30 of section B1a, the B2b of (most downstream) is connected with the first outflow access 33.
If so, making the group of the different first flow path 30 of the circulating direction of first fluid A alternately configure each first Macroportion B1 and the second macroportion B2 (the ratio benchmark stream Ra on first direction leans on a side and the another side of first direction). Therefore, the side of the heat exchange of the first fluid A and the second fluid B circulated in second flow path 31 that are circulated in first flow path 30 Formula (timing of heat transfer) is different according to the configuration of first flow path 30.Therefore, first fluid A from first flow into access 32 to First outflow access 33 can reliably be used for heat exchange.Thus, in (each first macroportion B1 and of whole main part 3 Two macroportion B2) in can obtain heat exchange performance higher.
In the above-described embodiment, first community section B1a, B2a and second community section B1b, B2b include three first respectively Stream 30, but not limited to this.For example, it is also possible to make first community section B1a, B2a and second community section B1b, B2b respectively comprising extremely A few first flow path 30, and the stream itself is connected with the first outflow access 33.Or, each first community section B1a, B2a and second community section B1b, B2b can also respectively by first community section B1a, B2a and second community section B1b, B2b bag The first flow path 30 that contains and form a stream for system, and become the first flow path 30 and first of its terminal and flow out access 33 connections.
In above-mentioned implementation method, the first macroportion B1 and the second macroportion B2 be divided into first community section B1a, B2a and Second community section B1b, B2b, but not limited to this.For example, first community section B1a, B2a and second community section B1b, B2b can be with Further it is divided into smaller section B1a1、B1a2、B1b1、B1b2、B2a1、B2a2、B2b1、B2b2.In this case, each The stream of the first fluid A in one macroportion B1 and the second macroportion B2 is symmetrical form on the basis of benchmark stream Ra.This In, section B1a1、B1a2It is the section after being made a distinction to first community section B1a.In addition, section B2a1、B2a2It is small to first Section B2a make a distinction after section.In addition, section B1b1、B1b2It is the section after being made a distinction to second community section B1b.Separately Outward, section B2b1、B2b2It is the section after being made a distinction to second community section B2b.
In above-mentioned implementation method, first community section B1a, B2a and second community section B1b, B2b are first-class comprising three respectively Road 30, these first flow path 30 are continuously connected, and thus, make the stream of first fluid A tortuous, but not limited to this.For example, first Away minor segment B1a, B2a and second community section B1b, B2b are respectively comprising multiple first flow path 30.And, multiple first flow path 30 may be used also All to be connected with secondary branch path 36b, 36b, and connected with the first outflow access 33.If so, first fluid A is from two After secondary branch path 36b, 36b flows into multiple first flow path 30, circulated in these multiple first flow path 30 and connected to the first outflow Path 33 flows out.So, first fluid A circulates in multiple first flow path 30, thus, the stream without extending first fluid A Length ensures that larger heat transfer area.As a result, the heat exchange performance of heat-exchangers of the plate type 1 can be improved.
