HEAT EXCHANGE DEVICE (VERSIONS) Russian patent published in 2010 - IPC F28D20/02 

FIELD: heating.

SUBSTANCE: in heat exchange devices there used is material with easy-changing phase states (hereinafter referred to as MECPS devices). It includes regenerative heat exchange modules (1a, 1b) operating as to counterflow principle, MECPS accumulators (2, 3) installed in heat exchange modules, and vortex tube (6, 7, 8). When directions of air, gas or liquid flows change cyclically in the device to the opposite ones, energy is accumulated in heat exchange module and in MECPS accumulator, and in the next cycle the energy is released from heat exchange module and MECPS accumulator. While one heat exchange module and MECPS accumulator are accumulating energy (being charged), the other heat exchange module and MECPS accumulator release energy (are discharged). Flows of cooled and heated fluid medium, which leave vortex tube, are used for creating or maintaining the required temperature difference.

EFFECT: device can be used in many cases, even when there is no external fluid medium, and namely in conditions when temperature difference of incoming and leaving fluid media is insufficient for using the effect of phase changes of MECPS, relatively low price, low noise level, weight reduction, easy serviceability, environmental safety.
