Title: Pin fin heat exchangers
IPC: F28F3/02
Filed: 1947-10-06
Abstract: 668,270. Plate heat exchangers. AIR PREHEATER CORPORATION. Oct. 6, 1947 [June 3, 1947], No. 26831/47. Class 64(iii) Parallel fins mounted on a wall separating two fluids exchanging heat each consists of a separate metal wire bent to form U-shaped loops with leg portions extending from the wall to form pin-like fins disposed in a plane or planes parallel to the direction of flow of the fluid stream and with the intervening yoke portions of the loops in contact with the wall over substantially all their length, good heat transfer bonds being provided between the yokes and the wall. Each wire is unconnected to other wires except by the wall or walls to which they are attached. In a plate heat-exchanger, Fig.5, for heating air by hot waste gases flowing at right angles to the air, the yoke portions 33 joining the leg portions 34 of the sinuously bent wires in the gas passages are flattened and welded to one or both of the plates 20, 21. The leg portions 34 may be perpendicular, as shown, or at angles greater or less than 90 degrees to the yokes 33. Fins in air passages may be sinuously bent lengths of wire, or as shown, channel strips 27 which may be either continuous and extend in the direction of gas flow or in short lengths arranged sinuously. The walls of the passages may be corrugated, the bends of the wire being shaped to fit in the troughs of the corrugations. In a modification, Fig. 9, the plates 43, 44 are corrugated, with the corrugations at 90 degrees or other angle to one another on successive plates. The wire elements are shaped so that the yoke parts 46, 47 between the fins 49 lie along the troughs. An air heater, Fig. 1, for use with a gas turbine comprises four sets of finned flat plate heat-exchangers 14, 16 arranged in a casing 11 with a hot gas inlet 10 and outlet 18 and a central baffle 12. Air passages extend between the plates from inlets 9 to outlets 19. Relative dimensions of pins and distances between plates are given. Specification 631,115 is referred to. The Specification as open to inspection under Sect. 91 describes also an air heater similar to that of Fig. 1 with an annular heat-exhange mass. the two walls of each hot gas passage being parallel to one another and the two walls of each air passage being inclined to one another. The pitch of the sinuosities in the wire fins decreases from one end to the other, and the channel strips decrease in width, as they increase in depth. In another heatexchanger, Fig. 13 (Cancelled), the fins 51, 52 form parts of wire coils which may be of rectangular or, as shown, trapezoidal form. In another form, simple pin fins are attached at their ends to the heatexchange plates. This subject-matter does not appear in the Specification as accepted.

Abstract: 845,417. Stretching. LOEWY ENGINEERING CO. Ltd. Sept. 5, 1957 [Sept. 10, 1956], No. 27664/56. Class 83 (4). A stretching-machine comprises a pair of spaced relatively-displaceable gripper-heads 1, 2, each comprising a pair of jaws, a pair of longitudinal frame members 9, 10 extending parallel to the direction of the applied stretching force and positioning each of said gripper-heads in relation one to the other, power means 6 for displacing one of said gripper-heads in a direction away from the other, and pressureloaded connecting-means 14 for coupling said frame-members to an anchor-point 13, said connecting-means permitting limited longitudinal displacement of the frame members after the pressure load has been overcome. The connecting means 14 for each frame member 9 or 10 comprises a fixed cylinder 15 with plungers 17 therein engaging cross-bars 19 guided by rods 18 secured to a frame-member 9 or 10 and rods 20 secured to a bar 21 bolted to the machine frame 13. If an eccentric or diagonal force on the frame members 9, 10 arise during stretching one frame member 9 or 10 is allowed to move longitudinally relatively of the other when the force exceeds a certain amount, one or other cross-bar 19 pushing its associated plunger 17 to overcome the resistance of a pressure-relief valve 15A on the cylinder 15. The gripper-head 1 is allowed to pivot slightly relatively to the frame members 9, 10 by virtue of resilient mountings 22, 23. Excess displacement of either cross-bar 19 operates a switch 28 to actuate means to discontinue the supply of pressure-fluid to the stretching power units 6. In case of sudden release of stretching force the connections 14 act as shock-absorbers. The end of the frame member 9 or 10 may directly contact one plunger 17, one of the bars 19 thus being dispensed with. A modified form of connecting-means 14, Fig. 4, includes two fixed cylinders 31 with pressure-relief valves 33 and plungers 29, 30 bearing against opposite faces of a cross-beam 38 carried by a frame member 9 or 10 on extension-rods 37.
