Abstract

PURPOSE: To lower the pressure loss of coolant to improve the performance and operation of a corrugated fin type heat exchanger, by varying the sectional area of flat heat transfer tubes through which coolant is circulated.
CONSTITUTION: A heat exchanger of this invention consists of tubes 8aW8C obtained by dividing a flat tube 8 into equal parts, intermediate headers 11A, 11B attached to both ends of the tube 8, a coolant inlet header 13 and a coolant outlet header 14 attached respectively to the middle portion of the tube 8C and tubes 8B, 8A, an inlet pipe 15, and an outlet pipe 16. Coolant supplied from the inlet pipe 15 is of a two-phase flow of vapor and liquid. After passing through the header 13, the coolant flow is divided into right and left portions of the tube 8C and the coolant is vaporized while passing through the tube 8C. About the time when the gas content of coolant is increased, it is introduced into headers 11A, 11B and gasified completely while passing through the tubes 18A, 18B, whereafter it is discharged to the outside from the header 14 and outlet pipe 16. Since, according to the above arrangement, the sectional area of the coolant passage is varied together with dryness of the coolant, it is enabled to prevent increasing of the velocity of gas flow and to thereby lower the pressure loss. Further, since, according to the above coolant circulating method, the amount of liquid coolant is sufficient on the upstream side of air flow, the temperature distribution of air passed through the heat exchanger can be rendered substantially uniform.
