摘要： [Summary]
A plate-type heat exchanger and a manufacturing method thereof are disclosed.
A plate type heat exchanger according to one aspect of the present invention includes a heat transfer assembly, wherein the heat transfer assembly includes a plurality of heat transfer shells stacked in multiple layers, wherein each of the heat transfer shells include a pair of heat conduction plates; wherein each of the heat conduction plates has a pair of flange portions bent at both side edges, and a first heat transfer portion and a second heat transfer portion facing each other at a certain distance by a bending portion bent and formed in the middle of the length; wherein the heat transfer shell includes a first passage, through which a first fluid passes, formed by welding the end of the first heat transfer portion of one of the pair of heat conduction plates and the end of the second heat transfer portion of the other heat conduction plate in contact with each other and by welding the end of the second heat transfer portion of the one heat conduction plate and the end of the first heat transfer portion of the other heat conduction plate in contact with each other; wherein the plurality of heat transfer shells are stacked in multiple layers by welding both side flange portions of the heat conduction plate provided in the heat transfer shell and both side flange portions of the other heat conduction plate provided in the other heat transfer shell, whereby a second passage through which a second fluid passes is formed between the adjacent heat transfer shells to intersect the first passage; and wherein heat exchange may occur between the first fluid passing through the first passage and the second fluid passing through the second passage without physical contact.

摘要： The present invention addresses the problem of providing a double-tube heat exchanger (1), which has a simple structure and with which it is easy to assemble an inner tube and an outer tube, and a manufacturing method therefor. The double-tube heat exchanger (1) has an outer tube (2) and an inner tube (3) inserted into the outer tube (2), forms an inside channel (4) within the inner tube (3) and an outside channel (5) between the inner tube (3) and the outer tube (2), and exchanges heat between the fluid flowing in the inside channel (4) and the fluid flowing in the outside channel (5). The inner tube (3) has an uneven portion (32) having unevenness on the outer peripheral surface. A large-diameter sealing portion (S 1) is interposed between one end (20) of the outer tube (2) in the axial direction and the inner tube (3). A small-diameter sealing portion (S2), which has a smaller diameter than the large-diameter sealing portion (S1), is interposed between the other end (21) of the outer tube (2) in the axial direction and the inner tube (3). The outside channel (5) and the uneven portion (32) are arranged using the difference in axial position and diameter between the large-diameter sealing portion (S 1) and the small-diameter sealing portion (S2).

摘要： A method for designing a pipe for use in chemical processing is disclosed. The pipe has a generally annular cross-section comprising an annular outer wall, and further comprising a number of fins provided on the inner surface of the outer wall. The geometry of the pipe is defined by one or more geometric parameters. The method comprises selecting values for the one or more parameters that minimise or maximise an optimisation function. The one or more parameters comprise one or more of: the number of fins, N fins ; the fin height H fin ; the inner diameter from fin peak to fin peak, D peak ; the inner diameter from fin trough to fin trough, D trough ; the inner diameter from fin mid-point to fin mid-point, D mean ; the fin trough radius of curvature, R trough ; the fin peak radius of curvature, R peak ; the outer diameter, D overall ; and the outer wall thickness, MSW. The optimisation function comprises one or more of: PAW = / Weight Perimeter Area Optimal = PAW ⋅ R trough H fin Removal = Area − π D peak 2 2 where "Perimeter" denotes the internal cross-sectional perimeter, "Area" denotes the internal cross-sectional area, and "Weight" denotes the weight per unit length. The method may further comprise making a pipe according to the design.

摘要： An in-line heat exchanger (10) comprising first (20) and second lengths (30) of seamless, walled tubing, the first length of tubing characterized by a larger diameter than the diameter of the second length of tubing, and the second length of walled tubing disposed within the first length of walled tubing. A plurality of longitudinally-extending channels (21) are defined in the wall of at least one of the first and second lengths of tubing, the channels (21) defining therebetween a plurality of longitudinally-extending passageways (40) in the area between the walls of the first and second lengths of tubing. Terminal portions (22a,22b) provided at opposite ends of the first length of tubing are each sealed with respect to the second length of tubing, each terminal portion defining one of an inlet or an outlet, and each terminal portion defining at least one interior passageway between the terminal portion and the wall of the second length of tubing, the at least one interior passageway (24a;24b) communicating the plurality of longitudinally-extending passageways (40) with one of the inlet or outlet.
