HEAT EXCHANGER Russian patent published in 1998 - IPC

FIELD: air coolers for gas turbines operated at considerable fluctuations of loads and/or temperature. SUBSTANCE: heat exchanger is effected through counter flow. Tubes 7 which are used as flow passages for heat-absorbing medium are located in twisting pattern between inlet pipe 5 and outlet pipe 6; heat-liberating medium flows around twisting tube 7. Hear exchanger 1 reliably compensates for frequency and quick changes in load and associated pressure and temperature fluctuations. Manifold pipes 5 and 6 pass on either side through casing 2 of heat exchanger 1. Pipes 5 and 6 are tightly connected with casing 2 on inlet and outlet sides and are directed to chamber 11 on opposite side tightly connected with casing 2. EFFECT: reliable compensation for frequent and quick fluctuations in load and associated pressure and temperature fluctuations. 5 cl, 3 dwg
