Title: Radiation-type heat exchanger
Inventor: SUMITOMO HIROYUKI
IPC: F28D9/00
Filed: 1979-06-13
Abstract: PURPOSE: To improve the operational performance, reduce the cost and make a radiation-type heat exchanger smaller in size as a whole by a method wherein a header pipe for supplying the heat-transfer side liquid to each heat exchanger is provided in the central position of heat exchangers arranged in the form of radiation.  
     CONSTITUTION: Each heat exchanger C is arranged radially and in the central position thereof is provided a round-shaped header pipe 11' for supplying the vapor to the vapor supply port 5 of each heat exchanger C. Moreover, on the circumference of the header pipe 11' pipings 13' in the same number with the heat exchanger C are arranged radially. Since the pipings 13' are arranged in this way, the distance from a nozzle 12' to each heat exchanger is equal, which enables even supply of vapor. The capacity of disposal of the vapor of each heat exchanger C is all the same, which results in the extremely high efficiency of the heat exchanger as a whole. In addition, the entier device occupies a smaller space than that so far used.
