Description of the Invention: [Technical Field of the Invention] The present invention relates to a plate heat exchanger laminate of a portion of the inner valley according to the first aspect of the patent application, and a plate heat exchanger including the same. [Prior Art] A plate heat exchanger having a laminate assembly of a plate heat exchanger laminate is used for heat exchange between two or more heat exchange fluids. The laminate constitutes the interior space of the laminate to allow heat exchange fluid to flow therethrough. The laminate has a through opening for forming a groove extending through the laminate assembly. In an application example in which heat exchange between the two heat exchange fluids occurs, each of the grooves is in communication with the interior space of each of the second laminates. The first heat exchange fluid flows from the first trench through each of the alternating interior spaces of the laminate above the heat exchange surface of the laminate to a second trench at opposite ends of the laminate assembly. a second heat exchange fluid flows from the third groove through each of the other alternately existing laminate spaces above the heat exchange surface on the opposite sides of the laminate to the opposite end of the laminate assembly The fourth groove 4 exchange fluid may be, for example, a gas, a liquid, a liquid containing: a solid substance, or the like. ...the heat exchange surface of the parent layer is textured. These lines may have different patterns 'but usually contain raised portions and depressions: bits. The texture can define the width of the inner space of the laminate, inside the laminate, and is used as a layer for the adjacent laminate in the laminate assembly. The laminate is usually made of sheet metal, sheet metal. Is in - times or more

The bruises and grooves make the V-shaped pattern resembling a fishbone pattern able to be formed in some parts of the laminate. When the v-shaped line pattern containing the ridge portion and the groove v is full/price is directed from the edge of the laminate toward the center of the laminate ± 'Because the sheet metal material is displaced during the pressing operation, the edge portion of the laminate will Deformation. Similarly, when the V-shaped pattern is placed near the edge of the laminate and the fingers are pointing in different directions, the associated edge portions will be affected. In addition to τ, the fullness of the J is not good, and the deformed edge will result in a weaker layer of the edge of the slab. The plate heat exchanger with a gasket placed in the middle of the laminate must have a strong and stable edge to prevent the plate heat exchanger from producing n A. Avoid weaker edges. The sheet metal blank of the exchanger laminate must be cut to be larger than the heat exchanger laminate with other grain patterns. In ‘Yes, the use of sheet metal materials is not the best. Patent WO 94/19657 discloses such a heat exchange II laminate in which the above-mentioned V-shaped pattern is directed to the center of the laminate and to the edge of the laminate. SUMMARY OF THE INVENTION One item of the present invention is to provide a plate type heat exchanger having a uniform moving edge, and as a result, allows the material to be obtained as a result of efficient use of the sheet metal material for heat transfer purposes.

According to an application embodiment, the plate heat exchanger can be applied to substantially maintain at least two heat exchange fluids. Parallel flow conditions occurring above the primary heat transfer site of the laminate within the laminate assembly. Further features and advantages of the present invention will become apparent when studying the scope of the appended claims and the following description. It will be appreciated by those skilled in the art that the various features of the present invention can be combined and produced in addition to the scope defined by the accompanying claims. Other embodiments of the described embodiments. The present invention will be described in detail herein with reference to the accompanying drawings, and exemplary embodiments are illustrated in the accompanying drawings. The present invention is not limited by the embodiments shown in the drawings, and the features disclosed in the embodiments can be incorporated into the present invention. Similar elements. For the purpose of streamlining and/or clear expression, conventional functions or configurations have not been described. Figure 1 schematically illustrates a plate heat exchanger laminate 2 in accordance with an exemplary embodiment. It is disposed in the laminate assembly of the plate heat exchanger. When the two fluids flow through the alternately existing interlayer space formed between the layers 2, the plate heat exchanger is configured to perform two heats. Heat exchange between the parent fluids. The laminate 2 is substantially rectangular and has two first side edges 4a, 4b for forming the shorter sides of the laminate 2 and having two second The face edges 6a, 6b are used to form the longer sides of the laminate 2 11 201209367. The laminate 2 has four opening holes 8a, 8b and 10a, 1 〇 b. The above-mentioned opening holes 8a, 8b, 10a, L〇b constitutes four trenches extending through the laminate assembly. Two of the above four trenches are in communication with the internal space of each of the second laminates and the other two of the above four trenches The groove is in communication with the inner space of the remaining laminate. In use, the first heat exchange fluid will flow through the first opening 8a above the side of one of the laminates 2, and flow to the second opening. 8b, and the second heat exchange fluid will flow over the other side of the laminate 2 between the second port opening 10a and the fourth port hole 1b. Therefore, from the two heat exchange fluids One of the heat of the heat exchange fluid will be transferred through the laminate 2 to another heat exchange fluid. Referring to the observable side of the ply 2 of Figure 1, there is a first dispensing portion 12a that is coupled to the first port opening 8a. The second dispensing portion 12b is then provided for connection to the second port opening 8b. The main heat transfer portion 14 is disposed between the first distribution portion 12a and the second distribution portion 12b. In use, the first dispensing portion 12a is used to distribute the associated fluid above the width of the primary heat transfer site 14. Therefore, the second distribution portion 12b is used to pass the fluid from the main heat transfer portion 14 to the second port hole 8b. The dispensing locations 12a, 12b are textured to provide efficient heat exchange fluid distribution and flow results. Located at the opposite side edges of the laminate 2 is a distribution portion that communicates with the third through hole i 〇 a and the fourth through hole l 〇 b. In use, these dispensing locations have the same function as the first dispensing portion i 2a and the second dispensing portion j, even though the heat exchange fluids applied are different. The ply 2 has a shim groove for receiving one or more shim.

S 12 201209367 When one or more gaskets are placed in the gasket groove between two adjacent laminates 2, the gasket limits the orifice, the distribution portion and the main heat transfer portion from the atmospheric environment. In the middle, and in use, the inner space of the laminate and the groove formed by the opening of the opening are sealed to prevent leakage of the heat exchange fluid. Thus, in the view illustrated in Fig. 1, the spacer 丨: 5 is placed in the spacer groove, and the spacer groove surrounds the first through hole 8a, the second through hole 8b, and the first An area of the distribution portion 12a, the second distribution portion i2b, and the main heat transfer portion 14. Similarly, the shim 丨 5 is disposed around each of the second through hole 1 and the fourth through hole b. On the other hand, a separate spacer can be used around each of the third through hole i〇a and the fourth through hole 10b. The main heat transfer portion 14 includes three main areas, that is, a first area, a first area, a first area, a 16 area, and a plurality of lines having a texture, and the texture is disposed between the first outer surface 18 and the second outer surface 2 It is a ridge portion and groove that includes 2 guides in different directions. In this application example: come: two such fields are in the first-area 16, in the figure is a continuous skirt... the first outer area 18 extends between the first-distribution site 12a and the first distribution site 12b , along the second side edge of the first solid side edge 'and contains three fields to, ^. The first outer portion is a second side edge extending from the first distribution portion (2) and the second distribution portion: (2) two = two side edges, and 匕 3 - field fields 24a, 24b, 24c. Bulge = more closely observe the direction of the ridges g and grooves of the above-mentioned fields in the 16th. For the purpose of illustration, the first straight line 26 is 13 201209367 : 2:: the second side edge 6a, and the intersection is again. The first field 3〇 is disposed on the side of the first straight line 26. The direction of the needle is measured in the direction of the '3' and the groove is guided at an angle of about 60 degrees from the first line 26^. The second field 4 32 is disposed on the opposite side of the first line %. The ridges and the ridges in the second field 32 are oriented at an angle of about _ degrees with the first line 26, as measured in the same direction as the ridges and recesses in the first field 3 〇. As with the second field 30', the second field 34 is disposed on the same side of the first line %. The third field 34 has a (four) portion and a groove, measured as before, (4) and concave. The groove is guided to maintain an angle of about 12 degrees from the first line %. Like the second field 32, the fourth field ^ is disposed on the same side of the first straight line 20, and the fourth field 36 has the raised portion again measured in the same direction as the previous one, and the ridge The portion and the groove are guided to maintain an angle of about 24 degrees with the first straight line 26. The first outer area 18 and the second outer area have protrusions: and recesses. In this embodiment, the protruding portion and the recess are formed as ridges and grooves similar to those in the first-area 16. In the outer areas 18, 20, the ridge portion and the groove have the same common direction in all three fields η(9)mi. In the first outer face (4), the ridges and grooves in the intermediate field & 22b have slightly different angles than in the two surrounding fields 22a, 22e. Similarly, in the second outer area 20, the raised portions and the grooves do not have the same direction in all three fields, two, and 24C. However, all three fields of the first outer area 18 and the second outer area 20 are mountainous to the mountain, W to... s 14 201209367 The grooves have the same common direction, that is, the ridges in the field without the field. One of the sides of the groove and the side edge of the groove are kept parallel to the _=: first side of the side 9 degree range. Brother - the straightness of the straight line 27 to the middle, when the gold is manufactured, the ~H way will cause the sheet metal to move, that is, during the pressing process, the 1 field will produce / slightly shift. The above lines are formed in the first field 3〇 and the first-domain 32' from the second side edge 6a, the edge of which points to the center of the layer 2, and the v-handle of the handle ... L Shape style. In the area of the v-shaped pattern, the sheet metal material can be moved toward the laminate 2 area 18 being disposed at the first-area and second side edges...==between 'in the pressing operation' the second side edge" wherein the side edges will It is evenly affected. During the operation of the gold material = 'the sheet metal at the rest of the layer 2: the section is displaced in different directions' However, the first outer area η is 2G to ensure the second side edge During the pressing operation, it is possible to be displaced along the main heat transfer portion 14 of the laminate 2. Thus, after the pressing operation, the second side edges 6a, 6b of the laminate 2 will also remain substantially flat. Circle 2 schematically illustrates a plate type heat exchange (four) 2 in accordance with an exemplary embodiment. In a general layout and function, the 'layer 2' corresponds to the layer 2 illustrated in the figure. Between the above two layers The main difference between them is the first facet 16 of the main heat transfer portion 14 of the laminate 2. The ridge portion of the first region 16 and the groove pattern in the first region 16 are constructed to be in the drawing. 15 201209367 The pattern of the texture is different β The area i6 comprises a number of fields, wherein the ridges and grooves of the grain are guided in different directions. The first line 26 is to be joined to the second side of the layer 2: the edges 6a, 6b. 3〇 is disposed on the side of the first straight line %. Measured in a clockwise direction, the raised portion and the groove in the first field 3〇 are guided to maintain about 4 degrees with the first straight line 26. The field 3 2 is disposed on the opposite side of the first line 26. The measurement is performed in the second field 32 in the same direction as the raised portion and the groove in the first field 3G. The raised portion and the groove are guided at an angle of about 320 degrees to the first m. The above pattern is in the first field port-field 32, which constitutes the first side from the second side edge The edge points to the V-shaped pattern of the second side edge 6 b of the second side edge. The first outer region 18 is again extended between the first distribution portion (2) and the first distribution portion 2b, along the first side edge of the second side edge 6a, and the second outer surface 20 extends Between the first dispensing portion 12a and the second dispensing portion (3), along the second side edge of the second side edge. In this embodiment, each of the outer areas 18, 2 曰 0 includes _ a pattern of the ridge portion and the convex portion of the groove and the field of the concave β. The raised portions and recesses in the first outer area 18 are only guided; the #upper' and the raised portions and recesses in the second outer area 2'' are only guided in the second direction. Each of the first-outer area 丨8 and the second outer area 2〇 and the protruding portion and the recess are guided in a direction associated with the first straight line 27 that is parallel to the first side edge 4a, for During the manufacturing process, when the layer 201209367 2 is provided with a grain pattern, it is kept straight. It is ensured that the first side edge 6a, 6b can have a larger area P 8 and a second outer area 20, respectively, than the first field 30 or the second field 32 which is maintained on the flat line with the first straight line 27 To be narrower. Therefore, the first outer region 18 and the second outer region 20 are further smaller than the portion t-area 16 of the main heat transfer portion 14. Figure 3 is a schematic view of a side view of a portion of a laminate assembly through a plate heat exchanger. The components described above correspond to the portions of the heat transfer laminate 2 having the P area 18 and the second outer area 2〇. The laminate 2 is provided with ridges of different widths in the outer 4 area 18 and the second outer area 2 与 and the recess I is in the outer area 18, 2 (), for example, all the ridge IP injuries may have the same The width, as well as all the grooves, may have the same width 'where the width of the groove is narrower than the width of the raised portion. Since the raised portions and the grooves have different widths, the interlayer internal space 42 between the two adjacent plies 2 will have different shapes at different sides of the same ply internal space 42. Therefore, the heat exchange fluid flowing through the inner space 42 of the laminate will be subjected to different flow resistance at different sides of the inner space 42 of the same laminate. The following will refer to the upper side, the left side and the right side of the layer 2 in the laminate assembly 4〇. The above results are purely for convenience of reference to Figure 3 and are not intended to limit the scope of the present invention. The ridges and grooves of each of the laminates 2 are formed in different ways on the left and right sides. That is, for example, the second laminate 2 from the top end of the laminate assembly 4 has a first outer area 18' on its left side and a second outer area 2'' on the right side. 17 201209367 In the view illustrated in Figure 3, the first - outer ^ ^. The 卩 area 丨 8 has a wider ridge portion and a relatively sloping groove, and the second outer 4 area 20 has a narrow ridge portion and a wider groove. The interior space 42 of the laminate between the two adjacent laminates 2 is on the left side of the laminate assembly 40, knowing that there are differences between the sides and the right side. As illustrated in Fig. 3, for example, a county _ such as an upper side panel 2 is configured such that on the left side, the top layer 2 is 筮 _ from the first outer area 20 and the second layer from the top The first outer area 18 of the panel 2 is adjacent. Since the wider ridge portion abuts to the wider groove, the flow resistance will be higher. Therefore, on the right hand side, since the narrow ridge portion abuts to the narrower groove, the flow resistance between the two uppermost layers 2 is lower. The plies 2 in the ply assembly 4G may be of the same kind. The arrangement of the first outer region 18 and the second outer region 20 of the different laminates 2 mentioned above is achieved by rotating each of the same types of laminates 2 along the vertical axis 44. And get it. By arranging the slabs in a suitable manner, the grooves formed by the through holes σ will pass through the laminate inner space 42 and be sealed. Frustration is as explained in connection with Fig. 1. The heat exchange fluid flows above the laminate 2 in a so-called parallel flow manner, that is, one of the hot parent fluids flows through the first through hole 8a and Between the second port & 8b, and another heat exchange fluid flows between the third port hole 1a and the fourth port hole 10b. In a parallel flow, the heat exchange fluid must flow through the hot parent of the laminate 2 over the width of the laminate 2 and the distance will be changed. The shortest distance will be along the closest first orifice 8a and The second side edge 6a of the second port hole 8b, and the longest distance will be from the first

S 18 201209367 The through hole 8a traverses the layer 2 to the opposite second side edge 讣, along the second side edge 6b and back across the layer 2 to the second opening 8b. Similarly, on the opposite sides of the laminate, the heat exchange fluid will flow directly through the shortest distance between the third port opening 10a and the fourth port opening 1b, and for the longest distance, heat The exchange fluid must, in its own right, traverse the laminate between the third port opening 10a and the fourth port opening (10). In use, since the flow resistance in each of the laminate inner space 42 and the same laminate internal space 42 is different, the distribution of the heat exchange fluid to each of the laminate internal spaces 42 will be affected. If the higher flow resistance is provided to the shortest path and the lower flow resistance is provided to the longest path, compared to if the flow resistance is in the shortest path and consistent, the former heat exchange fluid is on the entire relevant surface of the laminate 2: 3 The distribution. The situation will be more uniform. ▲ Figure 4 shows that the sun and the moon are in accordance with the exemplary embodiment of the plate type heat exchange $ 5〇. The plate heat exchanger 50 comprises a laminate 2, a laminate, and a member 40 according to any of the above exemplary embodiments. The cymbals (not shown in the figure) are placed between the slabs L. The deck assembly 40 is disposed within a frame 52 that includes a seesaw 54, an upper post 56, and a lower post 58. The laminate assembly is clamped between the shelf 54 and the pressure plate by the action of the bolts α and the nut 64. The shelf 54 has four openings σ 66, and each opening 66 is guided to In the laminate assembly 40, four through-holes of the laminate 2, (10) are formed by grooves. It should be understood by those skilled in the art that the exemplary embodiments can be exemplified. The outer area containing several fields may have a direction of the projections and recesses in all fields with 19 201209367. It will also be appreciated by those skilled in the art that the present invention can be applied to laminates of other types of plate heat exchangers other than plated hot parent exchangers having gaskets, such as welded or brazed plate heat exchangers. Although the present invention has been described with reference to the exemplary embodiments, it is apparent that many modifications, adaptations, and similar changes can be made to the present invention for those skilled in the art. Different fields within the main heat transfer portion of the laminate (ie, the field within the outer area and/or the first area) can be distinguished from each other by different grain patterns or directions of the grain pattern. come out. Such fields can also be separated by a dedicated composition in the laminate. Each field can be separated or the fields can be separated into two or more groups. Similarly, the laminate can be applied to the diagonal flow of the heat exchange fluid rather than to the parallel flow. That is, the heat exchange fluid can flow over the surface of the laminate intermediate the through-holes disposed along the diagonal direction at opposite ends of the laminate. In this application example, the first outer area and the second outer area of the main heat transfer portion of the laminate may be shaped such that the inner space of the laminate adjacent to the first outer area and the second outer area is substantially Also along the two side edges of the laminate.
