Title: Heat exchangers
IPC: F28F3/08
Filed: 1974-11-21
Abstract: 1484124 Plate heat exchangers ASSOCIATED ENG Ltd 21 Nov 1974 [31 Aug 1973] 41216/73 Heading F4S [Also in Division B3] A heat exchanger matrix comprises a series of contiguous, apertured, metal, plate elements, with together define one or more fluid flow passages, diffusion bonded together. A matrix 1 for a water cooled oil cooler, in one embodiment, comprises copper plates 5 arranged alternately with copper plates 6, the plates 5 having slots 5a and rows of apertures 5b and the plates 6 having slots 6a similar to the slots 5a and wider slots 6b. The assembly is solid state diffusion bonded together and end manifolds 2, 3 having channels 7, 8 and connecting ports 9, 10 are connected to the matrix, by diffusion bonding if made of copper or by adhesive bonding, soldering or brazing or mechanical fixing if of a different metal. In use the ports 9 are for oil to be cooled and the ports 10 for cooling water. In the heat exchanger the oil flows through the passages formed by apertures 5b and slots 6b, and the cooling water flows through the passages defined by apertures 5a and slots 6a. In another embodiment copper plates each with a large rectangular aperture are arranged alternately with copper plates each having three apertures and assembly is solid phase diffusion bonded. The end manifolds are secured by diffusion bonding or otherwise and oil only is passed through the cooler which is is arranged in a water hose. The large aperture may alternatively be divided into two and the inlet and outlet connections are then provided in one manifold, the other merely connecting the passages. The copper plates are provided with a commercially available finish of 20-50 micro inches CLA, are cleaned and degreased, possibly preheated by induction, and are heated at 700‹ C. for 30 minutes under a load of 1À3 ton per square inch in an atomosphere of cracked ammonia. The load may be applied by a jig having end plates 31, Fig. 3a connected by pillars 33 one plate 31 being loaded by springs 32. The jig is of material having a coefficient of expansion similar to that of the matrix. The pressure may be applied by nuts acting directly on the upper end plate when the pillars have a lower thermal expansion than the matrix. The end plates may alternatively have a higher expansion coefficient than the matrix. Stainless steel, nickel or nickel alloys may be the metals of the parts to be joined.

Tobacco is fed to a continuously operating revolving cutting device 37 by two vertical conveying devices, each comprising two parallel vertical conveyers 3, 4 and two conveying vertical conveyers 24, 25 offset through 90 degrees from a semicircular horizontal channel 2 in which a vane 16 filling the cross-sectional area of the channel is reciprocated under the control of a fluid operated device in dependance on the tobacco collecting in the channel. As shown, a bar 11, attached eccentrically to a rotating disc, is connected to a bevel gear segment 12 engaging a bevel gear 13 splined on a shaft 14 so as to reciprocate the shaft. A block 15 carrying the vane 16 is mounted on shaft 14 and has a toothed extension 38 which engages a toothed part 39 of a double piston 40 of an hydraulic device 17. The device 17 is so arranged that, if pressure of tobacco prevents vane 16 from completing its swing shaft 14 can continue its movement independently. Cams 18 and 19 on block 15 and cam 20 on shaft 14 control the speed of the motor driving conveyer belt 1 which deposits the leaf tobacco in channel 2 so as to reduce the quantity of tobacco supplied when too much tobacco collects in channel 2. Conveyer belts 24 are pivoted about their upper ends and are pressed against the tobacco being fed to the cutters by pistons 33 acting through bell-crank levers 32.

A relief valve (144), Fig. 2 (not shown), is provided in parallel with the valve 140 to relieve any excess pressure which may develop in the cylinder 64 arising from a surge of reverse flow in the check valve. The upper and lower piston-rods 80, 50 are made pressure balanced by interconnecting the chamber in which the rod ends move, by tubing (112), Fig. 2 (not shown), to which a next valve (160) is connected. A stop valve (116) allows, with vent valve (160) open, for the upper chamber 92 to be de-pressurized so allowing for a cap 96 to be removed after which a tool may be attached to the upper end of the piston-rod 80 for manual operation of the check valve. Facilities are also provided for pressurizing and recharging the hydraulic fluid in the cylinder 64. A disc 102 at the upper end of the piston-rod 80 actuates an indicator (170) to show if the check valve is open or closed. The piston 78 may have a small wheel passage through it.
