FIELD: process engineering.
SUBSTANCE: invention relates to chemical, petrochemical, power, pharmaceutical and food industries. Heat exchanger comprises case (1) with fluid and gas feed and discharge pipes, revolving drum (3) with radial blades (6) arranged in said case, said blades being arranged on inner surface over the drum entire length. Drum (3) has solid sidewall and end covers with radial forces arranged around the shaft for gas and fluid passage. Radial blades are made of sheet material and composed of sheet different-width bent parts while holes in the drum end covers do not overlap the blades end parts.
EFFECT: reduced fluid droplet entrainment, hence, higher efficiency of heat exchange processes in gas-fluid system.
