    HEAT TRANSFER PLATE FOR PLATE-AND-SHELL HEAT EXCHANGER AND PLATE-AND-SHELL HEAT EXCHANGER WITH THE SAME
    TECHNICAL FIELD
    [0001] Embodiments of the present disclosure relate to a heat transfer plate for a plate-and-shell heat exchanger and a plate-and-shell heat exchanger.
    BACKGROUND
    A typical plate-and-shell heat exchanger comprises a shell and a plurality of heat transfer plates stacked on a top of each other in the cavity of the shell. The heat transfer plates are formed with patterns such that first and second flow paths respectively formed between the neighboring heat transfer plates are alternately arranged in a direction perpendicular to the heat transfer plates. The shell comprises: a peripheral wall; a first inlet port and a first outlet port formed in the peripheral wall; an end wall; and a second inlet port and a second outlet port formed in the end wall. When first fluid enters the shell from the first inlet port, it tends to bypass central regions of the heat transfer plates where the patterns are formed, and to flow from the first inlet port to the first outlet port along peripheries of the heat transfer plates since a flow resistance along the peripheries of the heat transfer plates is lower than that of the central regions of the heat transfer plates where the patterns are formed, thereby resulting in a non-uniform distribution of the first fluid.

    DETAILED DESCRIPTION
    Referring to FIGS. 1-3, a plate-and-shell heat exchanger 100 according to an embodiment of the present disclosure comprises: a shell 50 defining a cavity 51; and a plurality of heat transfer plates 10 which are stacked on a top of each other in the cavity 51 of the shell 50. The shell 50 may have a cylindrical shape or any other appropriate shape.
    Referring to FIGS. 1-3, the shell 50 comprises a peripheral wall 52 extending in a peripheral direction around the plurality of heat transfer plates 10, and a first inlet port 61 and a first outlet port 62 which are formed in the peripheral wall 52. The shell 50 further comprises an end wall 53 such as a cover, and a second inlet port 71 and a second outlet port 72 which are formed in the end wall 53. The heat transfer plates 10 are formed with patterns such that first flow paths 81 and second flow paths 82 respectively formed between the neighboring heat transfer plates 10 are alternately arranged in a direction perpendicular to the heat transfer plates 10 or an axial direction of the shell 50. Sealing pieces 91 are formed around the openings 21 and 22 of the heat transfer plates 10 , and sealing pieces 92 are formed around peripheries 115 of the heat transfer plates 10 so that first fluid 102 enters the first flow paths 81 through the first inlet port 61 and flows out of the plate-and-shell heat exchangers er 100 through the first outlet port 62, while second fluid 103 enters the second flow paths 82 through the second inlet port 71 and flows out of the plate-and-shell heat exchanger 100 through the second outlet port 72.
    Referring to FIGS. 4 and 5, in an embodiment, the heat transfer plate 10 comprises: a plate body 11 having first and second sides 111, 112 opposite to each other in a direction perpendicular to the plate body 11; and a projection 12 protruding from the plate body 11 in a direction from the first side 111 towards the second side 112, extending along a segment 115S of a periphery 115 of the plate body 11, and having a first end 121 and a second end 122 The projection 12 may be spaced away from the periphery 115 of the plate body 11.
    Referring to FIGS. 4 and 5, the projection 12 comprises two projections 12 each extending along a segment 115S of the periphery 115 of the plate body 11, and the heat transfer plate 10 further comprises: a first gap 131 formed between the first ends 121 of the two projections 12 to form a first inlet 131P for the first fluid 102; and a second gap 132 formed between the second ends 122 of the two projections 12 to form a first outlet 132P for the first fluid 102. Each of the two projections 12 may extend continuously. With the projections 12 according to the embodiments, the projections 12 partly encircle the central region 101 and form a barrier along these peripheral sections of the heat transfer plates 10 when they are connected together. Thereby most of the first fluid 102 is prevented from entering the regions between the projections 12 and the periphery 115 of the plate body 11 of the heat transfer plates 10, and is forced to flow through the central region 101 from the first inlet 131P to the first outlet 132P. In one embodiment, there is a bypass flow 102B along the periphery 115 of the plate body 11 of the heat transfer plates 10 or between one or both of the projections 12 and the periphery 115 of the plate body 11 of the heat transfer plates 10, but the bypass flow 102B will improve the heat exchanging efficiency of the plate-and-shell heat exchanger 100.
    Referring to FIGS. 4 and 5, in an embodiment, the plate body 11 has an essentially circular shape, and the projection 12 extends along a curved line or an arc. However, the plate body 11 may have an essentially elliptical shape, an essentially rectangular shape, or the like, while the projection 12 may extend along a segment of an ellipse, a straight line, or the like.
    Referring to FIG. 4, in some embodiments, the heat transfer plate 10 may further comprises: a blocking protrusion 15 protruding from the plate body 11 in the direction from the first side 111 towards the second side 112, and extending from the projection 12 to the periphery 115 of the plate body 11. Referring to FIGS. 1 and 4, in other embodiments, the plate-and-shell heat exchanger 100 may further comprises a blocking piece 16 located between an inner wall surface 56 of the peripheral wall 52 of the shell 50 and the plate bodies 11 of the plurality of heat transfer plates 10, and between the first inlet port 61 and the first outlet port 62 in the peripheral direction. The blocking piece 16 may be abut against the projection 12 of each of the plurality of heat transfer plates 10. The blocking piece 16 may be made of stainless steel. For example, at least a part of the blocking piece 16 has a comb shape. The blocking piece 16 is a separate element from the heat transfer plate 10. The blocking protrusion 15 and the blocking piece 16 are shorter than the projection 12 in the peripheral direction. For example, the lengths of the blocking protrusion 15 and the blocking piece 16 in the peripheral direction are less than 1/10, 1/15 or the like of a length of the projection 12 in the peripheral direction.
    In an embodiment, the heat transfer plate 10 comprises one projection 12. Referring to FIGS. 1 and 3, the plate-and-shell heat exchanger 100 further comprises a sealing member 17 on a side of the heat transfer plates 10 where no projections 12 are provided.
    Although FIG. 5 show one blocking protrusion 15 on one side, and one blocking piece 16 on the other side, two blocking protrusions 15, two blocking pieces 16, or two sealing members 17 may be disposed on the two sides, respectively; one sealing member 17 and one blocking protrusion 15 may be disposed on the two sides, respectively; or one sealing member 17 and one blocking piece 16 may be disposed on the two sides, respectively.
    In an embodiment, the heat transfer plate 10 comprises: one projection 12. Referring to FIGS. 1 and 3, the plate-and-shell heat exchanger 100 further comprises a sealing member 17 on a side of the heat transfer plates 10 where no projections 12 are provided.
    Referring to FIGS. 4 and 5, each of a first distance between the first ends 121 of the two projections 12 and a second distance between the second ends 122 of the two projections 12 may be less than a length of each of the two projections 12, or 1 / 2 of the length of each of the two projections 12. For example, the plate body 11 has an essentially circular shape, and a central angle corresponding to the projection 12 is greater than 90 or 120 degrees or the like, so that the projection 12 has an sufficient length to prevent the first fluid 102 from bypassing a central region 101 of the heat transfer plate 10. The first distance between the first ends 121 of the two projections 12 may be greater than the second distance between the second ends 122 of the two projections 12. The sealing member 17 may have substantially the same length as the projection 12. For example, a central angle corresponding to the sealing member 17 is greater than 90 or 120 degrees or the like, so that the sealing member 17 has an enoug h length in the peripheral direction to prevent the first fluid from bypassing the central region 101 of the heat transfer plate 10.
    [0035] According to the embodiments of the present disclosure, the blocking protrusion 15, the blocking piece 16 and / or the sealing member 17 can at least partly alleviate the bypass flow 102B along the periphery 115 of the plate body 11 of the heat transfer plates 10 or between one or both projections 12 and the periphery 115 of the plate body 11 of the heat transfer plates 10.
    Referring to FIGS. 4 and 5, in some embodiments, the heat transfer plate 10 further comprises: a first opening 21 formed in the plate body 11 to form a second inlet 21P for the second fluid 103; and a second opening 22 formed in the plate body 11 to form a second outlet 22P for the second fluid 103. One of the first inlet 131P and the first outlet 132P, and one of the second inlet 21P and the second outlet 22P are located on one of two sides 113, 114 opposite in a direction parallel to the plate body 11, while the other of the first inlet 131P and the first outlet 132P, and the other of the second inlet 21P and the second outlet 22P are located on the other of the two sides 113, 114. For example, the first inlet 131P and the second inlet 21P are located on one (for example an upper side) of the two sides 113, 114, while the first outlet 132P and the second outlet 22P are located on the other (for example a lower side) of the two sides 113, 114.
    [0037] With the heat transfer plate 10 and the plate-and-shell heat exchanger 100 according to the embodiments of the present disclosure, the non-uniform distribution of the first fluid 102 can be at least partially alleviated.
