ROTATING HEAT EXCHANGER Russian patent published in 2006 - IPC F28D19/04 

FIELD: air conditioning or ventilation.

SUBSTANCE: rotating heat exchanger comprises frame separated into two spaces with a baffle that has bearings of the drum core. The core is defined by belts made of corrugated aluminum foil wound on the core with interference. The pulley of the drive of the wedge-belt transmission is secured to the core of the drum. The baffle of the frame with the drum defines the passages for inflowing and outflowing air. The cross-section of the corrugations of the aluminum belt represents a curve of the second or third order. The drum is defined by one belt wound on the core with a spaced relation over Archimedes spiral. The both edges of the belt are secured to the aluminum plates to provide round grids or perforated round disks rigidly connected with the core. A dispersion heat capacitive material with unclosed pores is interposed between the sides of the belts.

EFFECT: enhanced efficiency.
