Abstract

970,098. Tubular heat exchangers. TAYLOR, REID & CO. Ltd. July 26, 1963 [Aug. 22, 1962], No. 32156/62. Heading F4S. [Also in Division B3] A heat exchanger for heat transfer between two fluids comprises a plurality of cylindrical members, one within the other, in a cylindrical vessel, each member being formed from two cylindrical parts each having a helical groove such that when the two parts are assembled together, at least one helical passage for one of the fluids is formed from one end to the other of the member, an inlet and outlet for the other fluid being provided at opposite ends of the vessel. In the Figure, a plurality of the cylindrical members A<SP>1</SP>, A<SP>2</SP>, A<SP>3</SP> &c. are arranged coaxially in a cylindrical vessel B. Helical passages a<SP>1</SP>, a<SP>2</SP>, a<SP>3</SP> &c. arranged in the respective members, are independently connected to a fluid inlet pipe D<SP>1</SP> at the lower end and to a fluid outlet pipe D<SP>2</SP> at the upper end, said pipes being coaxial with the vessel. The other fluid passes over the surface of the members from its inlet E<SP>3</SP> at the top of the vessel to its outlet E<SP>4</SP> at the bottom. Each of the members A<SP>1</SP>, A<SP>2</SP>, A<SP>3</SP> &c. are constructed from two corrugated cylinders G<SP>1</SP>, G<SP>2</SP> as shown in Fig. 4, such that when the cylinders are joined between the corrugations, a helical passage a is formed. So that these helical passages are all of substantially the same length, the pitch of those in the outer members is greater than for those in the inner members, permitting several parallel passages in these outer members. The joining of the corrugated cylinders may be by spot or seam welding, or apertures may be cut in one of the parts for plug or fillet fusion welding using arc, argon arc, or even oxyacetylene gas welding. In a modification, each passage a<SP>1</SP>, a<SP>2</SP>, a<SP>3</SP> &c. may be joined to the next at its ends so that a fluid may pass into the innermost member and continue in series through each member to its outlet from the vessel. Baffles may be inserted in the upper and lower spaces of the vessel to cause the second fluid to flow along a tortuous path.
